BACKGROUND: Sentinel lymph node biopsy, step sectioning and immunohistochemistry have changed detection of tumour deposits. Isolated tumour cells (ITC) are detected more frequently than earlier because of a changed level of detection. METHODS: A total of 108 sentinel lymph nodes from 30 patients with T1/T2 cN0 oral cancer were re-classified histologically to find possible ITC and to describe technical pitfalls. RESULTS: Primarily we found metastatic spread in 12 of 108 sentinel lymph nodes: five macrometastasis and seven micrometastasis. After re-classification, we found seven lymph nodes with macrometastasis, five with micrometastasis and two with ITC. CONCLUSION: The ITC are probably precursors of micrometastasis waiting to grow and should be treated as such. Benign inclusions and dendritic cells did not cause problems, but can mimic ITC.

Background: The BODY-Q is a widely used patient-reported outcome measure for comprehensive assessment of treatment outcomes specific to patients undergoing body contouring surgery (BCS). However, for the BODY-Q to be meaningfully interpreted and used in clinical practice, minimal important difference (MID) scores are needed. A MID is defined as the smallest change in outcome measure score that patients perceive as important., Objectives: The aim of this study was to determine BODY-Q MID estimates for patients undergoing BCS to enhance the interpretability of the BODY-Q., Methods: Data from an international, prospective cohort from Denmark, Finland, Germany, Italy, the Netherlands, and Poland were included. Two distribution-based methods were used to estimate MID: 0.2 standard deviations of mean baseline scores and the mean standardized response change of BODY-Q scores from baseline to 3 years postoperatively., Results: A total of 12,554 assessments from 3237 participants (mean age 42.5 ± 9.3 years; BMI 28.9 ± 4.9 kg/m2) were included. Baseline MID scores ranged from 1 to 5 on the health-related quality of life (HRQL) scales and 3 to 6 on the appearance scales. The estimated MID scores from baseline to 3-year follow-up ranged from 4 to 5 for HRQL and from 4 to 8 on the appearance scales., Conclusions: The BODY-Q MID estimates from before BCS to 3 years postoperatively ranged from 4 to 8 and are recommended for interpretation of patients' BODY-Q scores, evaluation of treatment effects of different BCS procedures, and calculation of sample size for future studies., (© The Author(s) 2024.

Background  Direct-to-implant breast reconstruction (DIR) is becoming more and more accepted. There is a lack of high-quality studies assessing differences in patient-reported quality of life (QoL) between different implant placement methods. The aim of this randomized controlled (clinical) trial was to compare QoL between women reconstructed by sub- or prepectoral implant placement. Methods  We included women over 18 years eligible for DIR. Patients were randomly assigned to reconstruction by subpectoral or prepectoral implant placement. Assessment of QoL and patient satisfaction was made using the BREAST-Q questionnaire for postmastectomy breast reconstruction and compared between the sub- and prepectoral reconstructed groups preoperatively and after 3 and 12 months of follow-up. Results  A total of 42 women were allocated to sub- or prepectoral reconstruction with 21 patients in each group. There were no differences in patient characteristics between groups. Regarding all the selected BREAST-Q scales: (1) satisfaction with the reconstructed breast, (2) satisfaction with the breast implant, (3) satisfaction with the overall outcome, (4) psychosocial well-being, (5) sexual well-being, and (6) physical well-being-we found no significant differences between the two groups. Assessing each group independently we found, that in both groups sexual well-being improved after surgery postoperatively compared to the preoperative scores. Conclusion  We found high satisfaction and QoL following both sub- and prepectoral breast reconstruction. We found no significant differences between groups suggesting both methods for DIR can be used. Despite our high-quality data, a larger sample size and longer postoperative follow-up are needed to further investigate the differences in QoL between sub- and prepectoral breast reconstruction., Competing Interests: Conflict of Interest None declared., (The Author(s).

Background: The topographic anatomical changes of the upper arms and axilla after massive weight loss (MWL) seem ill-described in the literature. The importance of the axilla in MWL brachioplasty and how the procedure differs from the postmenopausal "batwing" deformity of the upper arms is also unclear. Consideration of the underlying pathology seems imperative for a successful reconstruction. We aim to test a procedure specifically designed to mend the underlying pathology of obesity and MWL, liposuction-assisted axillobrachioplasty (LAAB)., Methods: A prospective pilot study was designed to test the effect of LAAB on the axilla and evaluate the results comparative to patient's preoperative complaints and well-being and allow for adjustments for future trials. We measured the diameter of the arm and axilla at three specific points, A, B and C, and applied the arm module of BODY-Q regarding body perception and psychosocial well-being., Results: Fifteen women, for a total of 30 arms, were included. Age average was 48 years (29-59) and showed a significant improvement in all measurements A-C, most significantly at point A in the axilla, where the reduction was associated with relief of preoperative ailments and great improvement on BODY-Q ratings. The procedure was uncomplicated, with high patient satisfaction., Conclusions: LAAB significantly improves the axilla and upper arm contour after MWL and correlates strongly with improvement of preoperative ailments. The study furthermore supports the clinical relevance of a posterior arm fat pad. The presented procedure seems to be uncomplicated and reproducible with a high patient satisfaction warranting a long-term clinical trial., Competing Interests: The authors have no financial interest to declare in relation to the content of this article., (Copyright © 2024 The Authors.

BODY-Q is a patient-reported outcome measure for comprehensive assessment of outcomes specific to patients undergoing bariatric surgery. The clinical utility of BODY-Q is hampered by the lack of guidance on score interpretation. This study aimed to determine minimal important difference (MID) for assessment of BODY-Q. Prospective BODY-Q data from Denmark and the Netherlands pre- and post-bariatric surgery were collected. Two distribution-based methods were used to estimate MID by 0.2 standard deviations of baseline scores and the mean standardized response change of scores from baseline to 3-years postoperatively. In total, 5476 assessments from 2253 participants were included of which 1628 (72.3%) underwent Roux-en-Y gastric bypass, 586 (26.0%) sleeve gastrectomy, 33 (1.5%) gastric banding, and 6 (0.03%) other surgeries. The mean age was 45.1 ± 10.9 with a mean BMI of 46.6 ± 9.6. Baseline MID ranged from 1 to 4 in health-related quality of life (HRQL) and from 2 to 8 in appearance scales. The mean change of scores ranged from 4 to 5 in HRQL and from 4 to 7 in the appearance scales. The estimated MID for the change in BODY-Q HRQL and appearance scales ranged from 3 to 8 and is recommended for use to interpret BODY-Q scores and assess treatment effects in bariatric surgery., (© 2024 The Author(s).

Background and Objectives : Despite CTAs being critical for preoperative planning in autologous breast reconstruction, experienced plastic surgeons may have differing preferences for which side of the abdomen to use for unilateral breast reconstruction. Large language models (LLMs) have the potential to assist medical imaging interpretation. This study compares the perforator selection preferences of experienced plastic surgeons with four popular LLMs based on CTA images for breast reconstruction. Materials and Methods : Six experienced plastic surgeons from Australia, the US, Italy, Denmark, and Argentina reviewed ten CTA images, indicated their preferred side of the abdomen for unilateral breast reconstruction and recommended the type of autologous reconstruction. The LLMs were prompted to do the same. The average decisions were calculated, recorded in suitable tables, and compared. Results : The six consultants predominantly recommend the DIEP procedure (83%). This suggests experienced surgeons feel more comfortable raising DIEP than TRAM flaps, which they recommended only 3% of the time. They also favoured MS TRAM and SIEA less frequently (11% and 2%, respectively). Three LLMs-ChatGPT-4o, ChatGPT-4, and Bing CoPilot-exclusively recommended DIEP (100%), while Claude suggested DIEP 90% and MS TRAM 10%. Despite minor variations in side recommendations, consultants and AI models clearly preferred DIEP. Conclusions : Consultants and LLMs consistently preferred DIEP procedures, indicating strong confidence among experienced surgeons, though LLMs occasionally deviated in recommendations, highlighting limitations in their image interpretation capabilities. This emphasises the need for ongoing refinement of AI-assisted decision support systems to ensure they align more closely with expert clinical judgment and enhance their reliability in clinical practice.

This case presents a method of reductive cheiloplasty: Conway's method with lateral and bilateral wedge excisions contained to the vermillion. It was performed on a female patient with cheilitis granulomatosa after 4 years of trying different medical therapies without effect. The surgery successfully reduced the increased volume, facilitating improved aesthetics and function while preserving oral function, muscle strength as well as sensitivity with no recurrence at the 15-month follow-up. We encourage early collaboration between dermatologists and plastic surgeons regarding the timing of a potential surgery when treating cheilitis granulomatosa., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2024.

Knowledge of the long-term consequences of child sexual abuse (CSA) is crucial to further develop preventive strategies and treatment programs. The aim of this study is to investigate attachment and mentalizing ability in people who have experienced CSA. Attachment style, measured with the Experiences in Close Relationships-Relationship Structures Questionnaire (ECR-RS), and mentalization, measured with the Reflective Functioning Questionnaire (RFQ), were examined through a quantitative questionnaire survey in a sample of 49 individuals who had experienced CSA, and a control group of 612 with no history of CSA. The CSA group was, to a greater extent, identified with insecure attachment style. In addition, participants with insecure attachment were more likely to use hypomentalizing compared to individuals identified with a secure attachment. No significant association was found between attachment style and the relationship between the victim and the offender or the length of traumatic episodes.

Major depressive disorder is one of the most prevalent mental health disorders, posing a global socioeconomic burden. Conventional antidepressant treatments have a slow onset of action, and 30% of patients show no clinically significant treatment response. The recently approved fast-acting antidepressant S-ketamine, an N-methyl-D-aspartate receptor antagonist, provides a new approach for treatment-resistant patients. However, knowledge of S-ketamine's mechanism of action is still being established. Depressed human subjects have lower striatal dopamine transporter (DAT) availability compared to healthy controls. Rodent studies report increased striatal dopamine concentration in response to acute ketamine administration. In vivo [ 18 F]FE-PE2I ([ 18 F]-(E)-N-(3-iodoprop-2-enyl)-2β-carbofluoroethoxy-3β-(4'-methyl-phenyl) nortropane) positron emission tomography (PET) imaging of the DAT has not previously been applied to assess the effect of acute subanesthetic S-ketamine administration on DAT availability. We applied translational in vivo [ 18 F]FE-PE2I PET imaging of the DAT in healthy female rats to evaluate whether an acute subanesthetic intraperitoneal dose of 15 mg/kg S-ketamine alters DAT availability. We also performed [ 3 H]GBR-12935 autoradiography on postmortem brain sections. We found no effect of acute S-ketamine administration on striatal DAT binding using [ 18 F]FE-PE2I PET or [ 3 H]GBR-12935 autoradiography. This negative result does not support the hypothesis that DAT changes are associated with S-ketamine's rapid antidepressant effects, but additional studies are warranted., (© 2024 The Author(s).

Objective: To examine health-related quality of life (HRQL) and satisfaction with appearance in patients who have undergone bariatric surgery (BS) with or without subsequent body contouring surgery (BCS) in relation to the general population normative for the BODY-Q., Background: The long-term impact of BS with or without BCS has not been established using rigorously developed and validated patient-reported outcome measures. The BODY-Q is a patient-reported outcome measure developed to measure changes in HRQL and satisfaction with appearance in patients with BS and BCS., Methods: Prospective BODY-Q data were collected from 6 European countries (Denmark, the Netherlands, Finland, Germany, Italy, and Poland) from June 2015 to February 2022 in a cohort of patients who underwent BS. Mixed-effects regression models were used to analyze changes in HRQL and appearance over time between patients who did and did not receive BCS and to examine the impact of patient-level covariates on outcomes., Results: This study included 24,604 assessments from 5620 patients. BS initially led to improved HRQL and appearance scores throughout the first postbariatric year, followed by a gradual decrease. Patients who underwent subsequent BCS after BS experienced a sustained improvement in HRQL and appearance or remained relatively stable for up to 10 years postoperatively., Conclusions: Patients who underwent BCS maintained an improvement in HRQL and satisfaction with appearance in contrast to patients who only underwent BS, who reported a decline in scores 1 to 2 years postoperatively. Our results emphasize the pivotal role that BCS plays in the completion of the weight loss trajectory., Competing Interests: The BODY-Q is co-developed by A.L.P. and A.F.K., and as such, they receive a share of any license revenue based on their institution’s inventor-sharing policy.

Background and Objective: Perforator flaps have revolutionized autologous breast reconstruction, introducing both free and pedicled options as well as the potential for combining flaps. These versatile techniques can be utilized in massive weight loss (MWL) patients, effectively addressing both functional and aesthetic challenges by using their excess skin. This review aims to explore literature on combined pedicled and free perforator flaps for total breast reconstruction, and share our own experience in the field., Methods: A PubMed search up to June 2023 employed Medical Subject Headings (MeSH) terms such as (("combined") OR ("stacked") OR ("conjoined") AND ("perforator flaps")) AND ("breast reconstruction"). Publications in English and Scandinavian languages were manually screened for relevance, and supplemental sources were also reviewed., Key Content and Findings: Limited studies exist on using combined pedicled and free flaps for total breast reconstruction, although combined free flaps are more common. Perforators around the breast base, offer multiple flap options for single or combined use. In our series of 10 women, four underwent total breast reconstruction with a combination of flip-over internal mammary artery perforator (IMAP) flap and thoracodorsal artery perforator (TDAP) flap. Another subset of four, who were MWL patients, received combined TDAP and superior epigastric artery perforator (SEAP) flaps, along with body contouring procedures such as upper body lifts and vertical abdominoplasties, addressing excess skin and improving silhouette. One remaining MWL patient had deflated breasts restored using TDAP and SEAP flaps, along with an upper and lower body lift and vertical abdominoplasty. The last MWL patient underwent a risk-reducing mastectomy, also reconstructed with TDAP and SEAP flaps, and received an upper body lift and vertical abdominoplasty., Conclusions: Combined perforator flap techniques for combined body contouring and breast reconstruction seems safe and especially suitable for MWL patients. They offer a surgical alternative merging body contouring and breast reconstruction in cases where free flap procedures seem less favorable due to skin laxity and deflation of donor sites. However, limited literature on the topic calls for further studies., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://gs.amegroups.com/article/view/10.21037/gs-23-397/coif).

Background: Various surgical treatments are increasingly adopted and gaining popularity for lymphedema treatment. However, challenges persist in selecting appropriate treatment modalities targeted for individual patients and achieving consensus on choice of treatment as well as outcomes. The systematic review aimed to create a treatment algorithm incorporating the latest scientific knowledge, to provide healthcare professionals and patients with a tool for informed decision-making, when selecting between treatments or combining them in a relevant manner. This systematic review evaluated and synthesized the evidence on the effectiveness of three surgical treatments for breast cancer-related lymphedema (BCRL): lymphovenous anastomosis (LVA), vascularized lymph node transfer (VLNT), and liposuction., Methods: We conducted a systematic search of electronic databases on 18 June 2023, including Medline, Embase, Cochrane Library, Google Scholar, and ClinicalTrials.org. Eligible studies were randomized controlled trials, non-randomized comparative studies, and observational studies that assessed the outcomes of LVA, VLNT, or liposuction in managing BCRL. The primary results of interest were changes in arm volume, lymphatic flow, and quality of life. Two independent reviewers performed the study selection and data extraction. Following this, we systematically reviewed and conducted a risk of bias assessment. Results were qualitatively presented, and a treatment algorithm was developed based on the available data., Results: We identified 16,593 papers, after removal of duplicates. Following assessment of studies, 73 articles met the inclusion criteria, including 2,373 patients. We were not able to conduct a meta-analysis due to considerable heterogeneity in the methodologies and outcome measures across the studies. Liposuction appears effective for patients presenting with non-pitting lymphedema. LVA indicates variable success rate, with some evidence indicating a reduction in limb volume and symptomatic relief amongst early stages of lymphedema. VLNT showed promising results for limb volume reduction and symptom improvement in patients presenting with mild and moderate lymphedema., Conclusions: Liposuction, LVA, and VLNT seem to be effective treatments for BCRL, when targeted for the appropriate patient. Well-conducted high evidence clinical studies in the field are still lacking to uncover the efficacy of surgical treatment for BCRL., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://gs.amegroups.org/article/view/10.21037/gs-23-503/coif).

We present the first-in-human robot-assisted microsurgery on a lymphocele in the groin involving a man in his late 60s who had been coping with the condition for 12 months. Despite numerous efforts at conservative treatment and surgical intervention, the lymphocele persisted, leading to a referral to our clinic.Diagnostic techniques, including indocyanine green lymphography and ultrasound, identified one lymphatic vessel draining into the lymphocele. The surgical intervention, conducted with the assistance of a robot and facilitated by the Symani Surgical System (Medical Microinstruments, Calci, Italy), involved a lymphovenous anastomosis and excision of the lymphocele. An end-to-end anastomosis was performed between the lymphatic and venous vessels measuring 1 mm in diameter, using an Ethilon 10-0 suture.The surgery was successful, with no postoperative complications and a prompt recovery. The patient was discharged 3 days postoperatively and exhibited complete recovery at the 14-day follow-up. This case marks the first use of robot-assisted microsurgical lymphovenous anastomosis to address a groin lymphocele, highlighting the benefit of advanced robotic technology in complex lymphatic surgeries., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2024.

Background: Postherpetic neuralgia (PHN) is a chronic pain syndrome occurring after a herpes zoster outbreak. While there is no effective treatment available today, autologous fat grafting has shown promise. This randomized controlled trial investigated the effectiveness of fat grafting as treatment for PHN compared with a sham treatment., Methods: A total of 46 participants with PHN were included. After liposuction under general anesthesia, participants were randomly assigned to receive either autologous fat grafting or saline injection to the area of pain. The primary outcomes were the average and maximum degree of pain measured on an 11-point numeric rating scale. Secondary outcomes were quality and degree of neuropathic pain (Neuropathic Pain Symptom Inventory) and quality of life (36-Item Short-Form Health Survey)., Results: Forty-two participants completed follow-up of 6 months. For maximal degree of pain, a reduction of -1.1 ± 0.6 and -1.0 ± 0.5 mean change (±SE) on the numeric rating scale was observed in the intervention and control groups, respectively. For average degree of pain, the reduction was -1.2 ± 0.5 and -1.3 ± 0.4 in the intervention and control groups, respectively. The authors did not observe any significant changes in the neuropathic pain and quality-of-life parameters. For all measured outcomes, the differences between the groups were not statistically significant., Conclusions: The authors did not find autologous fat grafting superior to a placebo when treating PHN of the skin. Given their results, they cannot recommend the routine use of this method to treat these pains., Clinical Relevance Statement: Since autologous fat grafting was not proven to be more effective than a placebo in treating PHN, alternative treatment options should be explored. It is also essential to emphasize the importance of prophylactic vaccination against herpes zoster., Clinical Question/level of Evidence: Therapeutic, I., (Copyright © 2023 by the American Society of Plastic Surgeons.)

Information technologies are increasingly used when informing patients about their disease, treatment and prognosis. These digital platforms have many advantages compared to traditional education interventions. However, there are concerns that some patients may have difficulty with this mode of information delivery. Newly diagnosed breast cancer patients are dependent on understanding their treatment options to make informed treatment decisions. Yet, there is a lack of published material on breast cancer patients and their relationship with technology. We aimed to assess health technology readiness profiles amongst women with a suspected breast cancer diagnosis. Secondly, we wanted to investigate the potential differences between these profiles according to sociodemographic factors and the patients´ current use of technology. This cross-sectional study used the Readiness and Enablement Index for Health Technology (READHY) questionnaire. We included all patients (n = 92) referred to our department with suspected breast cancer. Cluster analysis revealed three distinct profiles: medium (n = 54), high (n = 18), and low (n = 20) health technology readiness. The third profile showed difficulties in health literacy, eHealth literacy, and health insights, along with higher emotional stress. Our study found that most patients had medium to high health technology readiness, but we also identified a group with lower health technology readiness. Based on our results, healthcare personnel dealing with women with suspected breast cancer should be aware of patients struggling with health technology. Age and technology familiarity may indicate vulnerable patients. Future studies should explore optimal methods for information delivery to these distinct profiles and evaluate the long-term impacts., (© 2023. The Author(s).)

Background: In respiratory gated radiotherapy, low latency between target motion into and out of the gating window and actual beam-on and beam-off is crucial for the treatment accuracy. However, there is presently a lack of guidelines and accurate methods for gating latency measurements., Purpose: To develop a simple and reliable method for gating latency measurements that work across different radiotherapy platforms., Methods: Gating latencies were measured at a Varian ProBeam (protons, RPM gating system) and TrueBeam (photons, TrueBeam gating system) accelerator. A motion-stage performed 1 cm vertical sinusoidal motion of a marker block that was optically tracked by the gating system. An amplitude gating window was set to cover the posterior half of the motion (0-0.5 cm). Gated beams were delivered to a 5 mm cubic scintillating ZnSe:O crystal that emitted visible light when irradiated, thereby directly showing when the beam was on. During gated beam delivery, a video camera acquired images at 120 Hz of the moving marker block and light-emitting crystal. After treatment, the block position and crystal light intensity were determined in all video frames. Two methods were used to determine the gate-on (τ on ) and gate-off (τ off ) latencies. By method 1, the video was synchronized with gating log files by temporal alignment of the same block motion recorded in both the video and the log files. τ on was defined as the time from the block entered the gating window (from gating log files) to the actual beam-on as detected by the crystal light. Similarly, τ off was the time from the block exited the gating window to beam-off. By method 2, τ on and τ off were found from the videos alone using motion of different sine periods (1-10 s). In each video, a sinusoidal fit of the block motion provided the times T min of the lowest block position. The mid-time, T mid-light , of each beam-on period was determined as the time halfway between crystal light signal start and end. It can be shown that the directly measurable quantity T mid-light - T min  = (τ off +τ on )/2, which provided the sum (τ off +τ on ) of the two latencies. It can also be shown that the beam-on (i.e., crystal light) duration ΔT light increases linearly with the sine period and depends on τ off - τ on : ΔT light  = constant•period+(τ off - τ on ). Hence, a linear fit of ΔT light as a function of the period provided the difference of the two latencies. From the sum (τ off +τ on ) and difference (τ off - τ on ), the individual latencies were determined., Results: Method 1 resulted in mean (±SD) latencies of τ on  = 255 ± 33 ms, τ off  = 82 ± 15 ms for the ProBeam and τ on  = 84 ± 13 ms, τ off  = 44 ± 11 ms for the TrueBeam. Method 2 resulted in latencies of τ on  = 255 ± 23 ms, τ off  = 95 ± 23 ms for the ProBeam and τ on  = 83 ± 8 ms, τ off  = 46 ± 8 ms for the TrueBeam. Hence, the mean latencies determined by the two methods agreed within 13 ms for the ProBeam and within 2 ms for the TrueBeam., Conclusions: A novel, simple and low-cost method for gating latency measurements that work across different radiotherapy platforms was demonstrated. Only the TrueBeam fully fulfilled the AAPM TG-142 recommendation of maximum 100 ms latencies., (© 2023 The Authors.

Background: Pencil beam scanning (PBS) proton therapy can provide highly conformal target dose distributions and healthy tissue sparing. However, proton therapy of hepatocellular carcinoma (HCC) is prone to dosimetrical uncertainties induced by respiratory motion. This study aims to develop intra-treatment tumor motion monitoring during respiratory gated proton therapy and combine it with motion-including dose reconstruction to estimate the delivered tumor doses for individual HCC treatment fractions., Methods: Three HCC-patients were planned to receive 58 GyRBE (n=2) or 67.5 GyRBE (n=1) of exhale respiratory gated PBS proton therapy in 15 fractions. The treatment planning was based on the exhale phase of a 4-dimensional CT scan. Daily setup was based on cone-beam CT (CBCT) imaging of three implanted fiducial markers. An external marker block (RPM) on the patient's abdomen was used for exhale gating in free breathing. This study was based on 5 fractions (patient 1), 1 fraction (patient 2) and 6 fractions (patient 3) where a post-treatment control CBCT was available. After treatment, segmented 2D marker positions in the post-treatment CBCT projections provided the estimated 3D motion trajectory during the CBCT by a probability-based method. An external-internal correlation model (ECM) that estimated the tumor motion from the RPM motion was built from the synchronized RPM signal and marker motion in the CBCT. The ECM was then used to estimate intra-treatment tumor motion. Finally, the motion-including CTV dose was estimated using a dose reconstruction method that emulates tumor motion in beam's eye view as lateral spot shifts and in-depth motion as changes in the proton beam energy. The CTV homogeneity index (HI) The CTV homogeneity index (HI) was calculated as D 2 %  -  D 98 % D 50 %   × 100 % ., Results: The tumor position during spot delivery had a root-mean-square error of 1.3 mm in left-right, 2.8 mm in cranio-caudal and 1.7 mm in anterior-posterior directions compared to the planned position. On average, the CTV HI was larger than planned by 3.7%-points (range: 1.0-6.6%-points) for individual fractions and by 0.7%-points (range: 0.3-1.1%-points) for the average dose of 5 or 6 fractions., Conclusions: A method to estimate internal tumor motion and reconstruct the motion-including fraction dose for PBS proton therapy of HCC was developed and demonstrated successfully clinically., Competing Interests: PP is co-inventor on a patent on the 3D motion estimation method applied in this study. The remaining authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.​, (Copyright © 2023 Nankali, Worm, Thomsen, Stick, Bertholet, Høyer, Weber, Mortensen and Poulsen.)

Patients with excess skin after massive weight loss often experience skin maceration, infection, wounding and reduced quality of life. Abdominoplasty is a surgical procedure that removes excess skin aiming to relieve physical inconveniences and improve quality of life. The abdominoplasty can be performed with different techniques using a horizontal, vertical and/or a circumferential procedure. The purpose of this review is to describe the indications for the different surgical approaches, the surgical principles and the complications following abdominoplasty in patients after massive weight loss.

Background  The incidence of breast animation deformity (BAD) is reported to be substantial after direct-to-implant breast reconstruction with subpectoral implant placement. It has, however, never been examined if BAD can occur following prepectoral implant placement. Our primary aim was to compare the incidence and degree of BAD after direct-to-implant breast reconstruction using either subpectoral or prepectoral implant placement. Secondary aim of this study was to assess and compare the level of pain between sub- and prepectoral reconstructed women. Methods  In this randomized controlled trial, patients were allocated to reconstruction by either subpectoral or prepectoral implant placement in accordance with the CONSORT guidelines. The degree of BAD was assessed by the "Nipple, Surrounding skin, Entire breast (NSE)" grading scale 12 months after surgery. The level of postoperative pain was assessed on a numerical pain rating scale. Results  We found a significant difference in the degree of BAD favoring patients in the prepectoral group (23.8 vs. 100%, p  < 0.0001; mean NSE grading scale score: 0.4 vs. 3.6, p  < 0.0001). The subpectoral reconstructed group reported higher levels of pain on the three subsequent days after surgery. No significant difference in pain levels could be found at 3 months postoperatively. Conclusion  The incidence and degree of BAD was significantly lower in women reconstructed by prepectoral direct-to-implant breast reconstruction. Unexpectedly, we found mild degrees of BAD in the prepectoral group. When assessing BAD, distortion can be challenging to discern from rippling., Competing Interests: Conflict of Interest D.L.D. received a 1-year salary sponsor fee from Groupe Sebbin SAS.

Background: Inguinal lymph node dissection (ILND) is associated with a high complication rate. Retrospective studies suggest that incisional negative pressure wound therapy (iNPWT) might reduce complications, especially seroma, following ILND., Methods: This was a prospective multicenter, randomized (1:1), open-labeled, parallel-group trial. Patients with macrometastic melanoma to the inguinal lymph nodes and eligible for ILND were randomized to receive either iNPWT for 14 postoperative days or conventional wound dressing. The primary outcome was seroma incidence. Secondary outcomes included surgical-site infection, wound rupture, wound necrosis, hematoma, rehospitalization and readmission rates between groups. All outcomes were registered 3 months after ILND and analyzed according to the intention-to-treat principle., Results: The trial was terminated early due to a low recruitment rate as a consequence of a change in the national treatment protocol, and the estimated sample size was not reached. Twenty patients were included and randomized in the study. The trial showed less seroma formation between the iNPWT 6/11 (55%) and control 7/9 (78%) groups; however, this was not statistically significant ( p  = 0.29). Similarly, there were no differences in the rates of surgical-site infection ( p  = 0.63), wound rupture ( p  = 0.19), wound necrosis ( p  = 0.82), hematoma ( p  = 0.19), reoperation ( p  = 0.82) or readmission ( p  = 0.34) between groups., Conclusion: There was a tendency toward fewer complications in the iNPWT group, however this trial was underpowered and could not confirm the hypothesis that iNPWT reduces complications after ILND. Future randomized controlled trials are required to fully evaluate the treatment potential of iNPWT., Trial Registration: The trial was prospectively registered at https://clinicaltrials.gov/ct2/show/NCT03433937., Competing Interests: None., (© 2022 The Authors.

The anterolateral thigh (ALT) flap is widely used in the reconstruction of a variety of soft tissue defects. Descriptions of patients with severe obesity in the literature are scarce. We report a case where a reverse pedicled fasciocutaneous ALT flap was successfully used for resurfacing of a knee defect measuring 12×6 cm in a patient with a body mass index (BMI) of 47.3. The flap was supercharged to the greater saphenous vein to optimise flap survival. Reconstruction of the soft tissue of the knee was achieved as planned. There were no flap or donor site complications., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2022. No commercial re-use. See rights and permissions.

Background: Variability in breast reconstruction methods provides an opportunity to investigate whether a method is superior to another with regard to cost, quality, or both. We performed a cost-effectiveness analysis (CEA) study based on tertiary endpoint data from a randomized clinical trial to compare the cost-effectiveness of delayed breast reconstruction by either a latissimus dorsi flap (LD) or a thoracodorsal artery perforator flap (TAP)., Material & Methods: A total of 50 women were included for unilateral delayed breast reconstruction and were randomized to reconstruction by either the LD flap (n = 18) or the TAP flap (n = 22). The CEA was based on differences in shoulder function after the reconstruction. Direct and indirect costs relating to the two procedures were assessed by the Danish Diagnosis-Related Groups tariffs., Results: Our analysis showed a significant positive effect of introducing the TAP flap on the total shoulder score with an additional cost of $2779. The incremental cost-effectiveness ratio was $4481 and based on a willingness to pay (WTP) $500, we found an estimated net benefit of $519, which was statistically significant (p = 0.0375). The cost-effectiveness acceptability curve indicated that there is a 96.3% probability for the TAP flap being cost-effective to the LD flap at a WTP threshold of $500., Conclusion: From a societal perspective, our cost-effective analysis demonstrated that the TAP flap is the more cost-effective method of breast reconstruction compared to the LD flap with respect to patient-reported shoulder-related disability., Competing Interests: Declaration of Competing Interest None, (Copyright © 2022 Elsevier Ltd.

Massive weight loss (MWL) results in significant changes of the female breast becoming deflated, ptotic and flat in the upper pole. It may cause physical discomfort such as infections, intertrigo and psychological discomfort including reduced health-related quality of life, where subsequent corrective surgery of the breast is indicated. In this review, we outline our experiences of the most commonly used surgical techniques for correction of the breast in women after MWL. We highlight the principles of the various surgical techniques.

Background: Postmastectomy pain syndrome is a common and disabling side effect of breast cancer treatment. Medical treatment seems to be insufficient for a considerable proportion of patients. Fat grafting has shown promise in relieving pain from postmastectomy pain syndrome, but no randomized clinical trial comparing fat grafting to a sham operation has been performed to date. The authors' objective was to compare the effect of fat grafting compared to a sham operation for treating postmastectomy pain syndrome., Methods: The authors conducted a single-center, double-blind, randomized clinical trial with two arms between October of 2017 and September of 2020. The authors assessed four patients suffering from postmastectomy pain syndrome for inclusion. The intervention group received scar-releasing rigottomy and fat grafting to the area of pain. The control group received scar-releasing rigottomy and a placebo of saline solution. The primary outcome was the degree of pain measured using the Numerical Rating Scale. The secondary outcomes were the degree and quality of neuropathic pain (Neuropathic Pain Symptom Inventory) and quality of life (36-Item Short-Form Health Survey). Follow-up was 6 months., Results: Thirty-five participants completed follow-up: 18 participants in the intervention group and 17 in the control group. The authors detected no statistically significant changes in average and maximum pain or neuropathic pain. Regarding quality of life, the control group reported a statistically significant improvement in emotional problem parameters, whereas the intervention group reported a deterioration. The authors observed no serious adverse effects., Conclusion: The authors did not find evidence to support that fat grafting is superior to a placebo when treating postmastectomy pain syndrome., Clinical Question/level of Evidence: Therapeutic, I., Competing Interests: Disclosure: The authors have no relationships, conditions, or circumstances that present potential conflict of interest in relation to the content of this article.

The number of patients undergoing bariatric surgery is increasing worldwide. Different types of free flaps are often used for breast reconstruction following mastectomy. We present a not previously described case using a vertical myocutaneous gracilis flap for breast reconstruction in a massive weight loss patient. The patient was a 61 year-old woman who previously had a lumpectomy for an in situ ductile carcinoma of her left breast. Subsequently the patient underwent a full mastectomy in 2020 due to a recurrence. The massive weight loss population poses a challenge in reconstructive surgery, due to their higher risk of complications. However, we still believe free flaps should be considered as a valid option for breast reconstruction in these patients. Due to the often increased size of perforator vessels in these patients, other flaps may prove more suitable than the usually preferred ones., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2021.

Background: This paper presents the results of a randomized controlled trial (RCT) that focus on health-related quality-of-life (QoL) and patient-reported satisfaction following breast reconstruction with pedicled flaps from the back., Materials & Methods: We included women for unilateral delayed breast reconstruction. Patients were randomized to reconstruction by either a latissimus dorsi (LD) flap or a thoracodorsal artery perforator (TAP) flap. Assessment of QoL and patient satisfaction was made using two different patient-reported outcome measures (PROMs): The EORTC QLQ-30 and the Breast-Q questionnaire for post-mastectomy breast reconstruction., Results: A total of 50 women were enrolled over a two-year period and allocated to reconstruction. Forty patients completed both surgery and follow-up and were included in the analysis - 18 in the LD group and 22 in the TAP group. The EORTC QLQ-30 was administered at the baseline and at one-year follow-up. There was no significant effect of introducing the TAP flap on either the summary score, the global QoL-score or the financial impact-score when compared to the LD flap. The Breast-Q questionnaire was administered only at one-year follow-up. There was no significant difference between the two groups for the scores for satisfaction with the reconstructed breast, the overall outcome and QoL related to psycho-social, sexual and physical well-being., Conclusion: Women from both groups report high satisfaction and QoL following the reconstruction. The quality of the dataset and the study design are, however, insufficient to rule out any existing difference. A larger cohort, longer follow-up and different design are warranted to assess the true clinical significance these reconstructions might have on satisfaction and QoL., Competing Interests: Declaration of Competing Interest The first author has received a donation of ADM (Strattice(Ⓡ)) from Acelity™ to be used in the randomized clinical trial.

Cellulitis is a common complication in Breast Cancer-Related Lymphedema (BCRL). The excess amount of fat and lean mass in BCRL is a vital factor in patient stratification, prognosis, and treatments. However, it is not known whether cellulitis is associated with the excess fat and lean mass in BCRL. Therefore, this prospective observational study was designed to fundamentally understand the heterogonous biocomposition of BCRL. For this study, we consecutively enrolled 206 patients with unilateral BCRL between January 2019 and February 2020. All patients underwent Dual-Energy X-Ray Absorptiometry scans, bioimpedance spectroscopy, indocyanine green lymphangiography comprehensive history of potential risk factors, and a clinical exam. Multivariate linear and beta regression models were used to determine the strength of association and margins effect. Sixty-nine patients (33%) had at least one previous episode of cellulitis. Notably, a previous episode of cellulitis was associated with 20 percentage points more excess fat and 10 percentage points more excess lean mass compared to patients without cellulitis ( p < 0.05). Moreover, each 1 increase in the patients BMI was associated with a 0.03 unit increase in the fat mass proportion of the lymphedema arm. Cellulitis was associated with more excess fat and lean arm mass in BCRL. In addition, patients BMI affect the proportion of fat mass in the arm.

Indocyanine green lymphangiography (ICG-L) allows real-time investigation of lymphatics. Plastic surgeons performing lymphatic reconstruction use the ICG-L for patient selection and stratification using the MD Anderson (MDA) and the Arm Dermal Backflow (ADB) grading systems. However, the applicability of ICG-L in evaluating breast cancer-related lymphedema (BCRL) is sparse and not well established. This study comprehensively examines the usability of ICG-L in the assessment of BCRL. We prospectively performed ICG-L in 237 BCRL patients between January 2019 and February 2020. The aim of this study was to assess the interrater and intrarater agreement and interscale consensus of ratings made using the MDA and ADB scales. Three independent raters performed a total of 2607 ICG-L assessments. The ICG-L stage for each grading system was correlated to the lymphedema volume to assess the agreement between the ICG-L stage and clinical severity. The interrater agreement was near perfect for the MDA scale (kappa 0.82-0.90) and the ADB scale (kappa 0.80-0.91). Similarly, we found a near-perfect intrarater agreement for the MDA scale (kappa 0.84-0.94) and the ADB scale (kappa 0.88-0.89). The agreement between the MDA and the ADB scales was substantial (kappa 0.65-0.68); however, the ADB scale systematically overestimated lower ICG-L stages compared to the MDA scale. The volume of lymphedema correlated slightly with MDA stage (Spearmans rho = 0.44, p < 0.001) and ADB stage (r s = 0.35, p < 0.001). No serious adverse events occurred. The staging of BCRL with ICG-L is reliable, safe, and provides unique disease information unobtainable with clinical measurements alone. The MDA scale seems to provide better disease stratification compared to the ADB scale.

Background: Postherpetic neuralgia (PHN) is a relatively common side effect after an outbreak of herpes zoster (HZ), characterized by chronic neuropathic dermal pain. No effective treatment exists today. Fat grafting has shown promise in alleviating neuropathic pain, yet the exact mechanism of action, at a biological level, is not yet known. We report on the first human study using autologous fat grafting for treating PHN. Our hypothesis was that fat grafting can alleviate pain and improve the quality of life (QoL) in patients suffering from PHN. If successful, this could be a safe, cost-effective alternative to analgesics. This safety and feasibility study aimed to investigate the possible pain-relieving effect of autologous fat grafting on PHN., Methods: Ten adult patients suffering from PHN underwent autologous fat grafting to a dermal area of neuralgia, with a 12-week follow up. The primary endpoint was patient-reported pain. Secondary endpoints were patient-reported changes in QoL, and the degree and quality of the neuropathic pain., Results: The pain was measured by using a visual analog scale (range: 0-10). We observed improvements in both the average and maximum level of pain with a reduction of (-4.0 ± 3.1) and (-5.1 ± 3.9), respectively, (Δ mean ± SD), P<0.05. All parameters investigating neuropathic pain were significantly reduced. No improvement was seen in the QoL. The average amount of fat grafted was 208 ml. We observed no serious adverse effects., Conclusion: This study suggests that autologous fat grafting can relieve chronic pain resulting from HZ. The next step toward routine clinical translation is to perform a randomized, blinded, placebo-controlled trial with a more extended follow-up period., Competing Interests: Declaration of Competing Interest None., (Copyright © 2020 Elsevier Ltd.

Background: Breast reshaping or mastopexy following massive weight loss can be challenging. The LOPOSAM (lower pole subglandular advancement mastoplasty) technique has shown promising results for correction of ptotic, wide, lateralized and deflated breasts following massive weight loss., Materials and Methods: We compared the LOPOSAM technique to the mastopexy technique after massive weight loss described by Rubin JP, in a randomized trial. The main outcome measure was the total operative time. Secondary outcomes measures were socio-economic factors; length of hospital stay, numbers of sutures used, secondary corrective procedures, post-operative sick leave and surgeon- and patient-reported appearance of the breasts., Results: We included 22 women: 11 operated on by the LOPOSAM technique and 11 by the technique described by Rubin JP. The total operative time was 84.8 (SD 12.2) minutes in the LOPOSAM group and 99.1 (SD 23.5) in the Rubin JP group (p = 0.074). There were no differences related to days with drains, length of hospital stay or sick leave between the two groups. The surgeon- and the patient-reported appearance of the breasts changed significantly between the pre-operative and the 12-month post-operative assessments., Conclusion: The LOPOSAM technique is a safe and quick surgical procedure for correction of ptotic, wide, lateralized and deflated breasts following massive weight loss and seems to provide results comparable to the better-known Rubin JP's technique. There was a trend that the LOPOSAM technique was faster to perform, however, not significant. The breast appearance improved significantly using both techniques when assessed by both surgeons and patients., Level of Evidence Iv: This journal requires that authors assign a level of evidence to each article.

Thoracodorsal artery (TDA) flaps, ranging from the vascular-pedicled thoracodorsal artery perforator (TDAP) flap, the propeller TDAP flap, and the muscle-sparing latissimus dorsi (MSLD) flap to the conventional latissimus dorsi (LD) flap and the extended LD flap, can all be used for breast reconstruction. The aim of this paper and review is to share our experiences and recommendations for procedure selection when applying TDA-based flaps for breast reconstruction. We describe the different surgical techniques and our thoughts and experience regarding indications and selection between these procedures for individual patients who opt for breast reconstruction. We have performed 574 TDA flaps in 491 patients: 60 extended LD flaps, 122 conventional LD flaps, two MSLD flaps, 233 propeller TDAP flaps, 122 TDAP flaps, and 35 free contralateral TDAP flaps for stacked TDAP breast reconstruction. All the TDA flaps are important flaps for reconstruction of the breast. The LD flap is still an option, although we prefer flaps without muscle when possible. The vascular-pedicled TDAP flap is an option for experienced surgeons, and the propeller TDAP flap can be used in most reconstructive cases of the breast, although a secondary procedure is often necessary for correction of the pedicle bulk. The extended LD flap is an option for women with a substantial body mass index, although it is associated with the highest morbidity of all the TDA flaps. The MSLD flap can be used if the perforators are small or if dissection of the perforators is assessed to be hazardous.

Background: Breast cancer is the most common cancer in Danish women. In 2016 about 1450 (31%) Danish breast cancer patients had a mastectomy. The aim was to compare the frequency of postoperative complications in two methods of surgery, electrocautery dissection and tumescent technique, when performing a mastectomy., Methods: Open randomized controlled trial of all consecutive primary breast cancer or DCIS female patients who underwent either a simple mastectomy or a modified radical mastectomy in Vejle Hospital, from January 2012 to October 2017. Primary outcomes were seroma production, bleeding, infection and necrosis. Secondary outcomes were duration of surgery and delay of adjuvant treatment caused by complications. Categorical outcome variables were compared between randomization groups using chi-square of Fisher exact test and continuous outcome variables by using Wilcoxon rank test. All analyses were performed at a 5% two-sided significance level., Results: 357 patients met the inclusion criteria. 14 had bilateral mastectomy, i.e. 371 breasts. The two randomization groups consisted of 105 patients/107 breasts operated by tumescent technique and 98 patients/102 breasts operated by electrocautery technique. Tumescent technique produced more seroma though not significant (p = 0.631) (mean 605 vs. 630 ml). Bleeding in the tumescent group was 10.3% vs. 5.9% in the electrocautery group (p = 0.245). Infection (5.9% vs. 7.5% p = 0.645) and necrosis (4.9% vs. 4.7% p = 0.938) was uncommon with no difference between the intervention groups. Infection was most common cause of delay of adjuvant treatment; 3.9% in the electrocautery technique group. No significant difference in duration of surgery (p = 0.392)., Conclusion: Both techniques are equally safe for simple and modified radical mastectomy., (Copyright © 2020 Elsevier Ltd.

Background: Skin-sparing mastectomy followed by immediate implant-based breast reconstruction is a commonly used treatment for breast cancer. However, when placing the implant in a subpectoral pocket, a high incidence of breast animation deformity (BAD) has been reported. Besides the nuisance that BAD can cause, lifting of the pectoralis major muscle (PMM) can result in a more extended postoperative recovery period. When placing the implant solely prepectorally leaving the PMM undisturbed, the incidence and severity of BAD might be mitigated. However, new challenges may occur because of thinner skin cover., Methods/design: A prospective, multi-centre, randomised controlled trial will be carried out with the primary aim of assessing and comparing the incidence and degree of BAD in women having a direct-to-implant breast reconstruction with either a prepectorally or a subpectorally placed implant. The secondary outcomes are shoulder and arm function, quality of life, aesthetic evaluation, length of stay, complications, need for surgical corrections, and development of capsular contracture. A total of 70 included patients will be followed under admittance and at clinical check-ups 3 months and 1 year after surgery., Discussion: To our knowledge, this trial is the first randomised controlled trial evaluating and comparing subpectoral and prepectoral implant placement when performing direct-to-implant breast reconstruction following skin-sparing mastectomy. The results will hopefully provide us with a broader knowledge of the outcomes of immediate breast reconstruction, making better preoperative planning possible in the future by providing our patients with a more objective information., Trial Registration: ClinicalTrials.gov, ID: NCT03143335. Prospectively registered on 8 May 2017.

Objectives: Patients with locally advanced non-small cell lung cancer (NSCLC) were included in a prospective trial for radiotherapy in deep inspiration breath hold (DIBH). We evaluated DIBH compliance and target position reproducibility., Methods: Voluntary, visually guided DIBHs were performed with optical tracking. Patients underwent three consecutive DIBH CT scans for radiotherapy planning. We evaluated the intrafractional uncertainties in the position of the peripheral tumour, lymph nodes and differential motion between them, enabling PTV margins calculation. Patients who underwent all DIBH imaging and had tumour position reproducibility <8 mm were up-front DIBH compliant. Patients who performed DIBHs throughout the treatment course were overall DIBH compliant. Clinical parameters and DIBH-related uncertainties were validated against our earlier pilot study., Results: 69 of 88 included patients received definitive radiotherapy. 60/69 patients (87%) were up-front DIBH compliant. DIBH plan was not superior in seven patients and three lost DIBH ability during the treatment, leaving 50/69 patients (72%) overall DIBH compliant.The systematic and random errors between consecutive DIBHs were small but differed from the pilot study findings. This led to slightly different PTV margins between the two studies., Conclusions: DIBH compliance and reproducibility was high. Still, this validation study highlighted the necessity of designing PTV margins in larger, representative patient cohorts., Advances in Knowledge: We demonstrated high DIBH compliance in locally advanced NSCLC patients. DIBH does not eliminate but mitigates the target position uncertainty, which needs to be accounted for in treatment margins. Margin design should be based on data from larger representative patient groups.

Background: This randomized controlled trial (RCT) investigates differences in shoulder-related morbidity after delayed breast reconstruction by either a latissimus dorsi (LD) flap or a thoracodorsal artery perforater (TAP) flap., Material and Methods: In accordance with the CONSORT guidelines, we included women for unilateral delayed breast reconstruction. Patients were randomized to reconstruction by either of the two flaps. Shoulder-function was assessed at baseline and at 3, 6 and 12 months after surgery. The primary endpoint was patient-reported shoulder-related pain. A further objective assessment by the Constant Shoulder Score (CSS) was included as secondary endpoints., Results: A total of 50 women were enrolled over a two-year period and allocated to reconstruction, with 25 patients in each group. Patient-reported shoulder-related pain was significantly lower in the TAP group at 12 months after surgery when adjusting for pain at baseline: OR = 0.05 95%CI(0.005-0.51), p-value = 0.011. The estimated effect on the total CSS at 12 months, when applying the TAP flap instead of the LD flap and adjusting for the baseline score, was 6.2 points with 95%CI(0.5-12.0), p-value 0.033. The TAP flap seems to have a statistically significant positive effect on pain and activity in daily life (ADL), while there were no significant effect on range of motion and strength after one year., Conclusion: Patient reconstructed by the TAP flap are less likely to experience shoulder-related pain and have a better shoulder-function one year after the reconstruction. Harvest of the LD flap carries a higher risk of shoulder-function impairment, chronic pain and reduced ADL., (Copyright © 2019 Elsevier Ltd. All rights reserved.)

Background: A high incidence of breast animation deformity (BAD) has been reported following immediate breast reconstruction with subpectorally placed implants. The aim of this study was to assess and compare the incidence of BAD in women who underwent either subpectoral or prepectoral immediate breast reconstruction. Therefore, we developed a grading tool and tested its reproducibility in a clinical setting., Methods: Video recordings of 37 women who had undergone unilateral or bilateral immediate breast reconstruction were evaluated by two consultant plastic surgeons. The degree of BAD was assessed by our grading tool, named the Nipple, Surrounding Skin, Entire Breast (NSE) grading scale, which evaluates the degree of tissue distortion in three areas of the breast. Blinded assessments were performed twice by each observer., Results: Eighteen patients were reconstructed with subpectoral implant placement and 19 with prepectoral implant placement. Using the NSE grading scale, we found a significant difference in the degree of BAD between the groups, in favor of patients who underwent prepectoral immediate breast reconstruction (0.2 vs. 4, P=0.000). Inter- and intraobserver agreement was moderate (74%) to strong (88%)., Conclusions: The incidence and severity of BAD was significantly lower in women reconstructed with a prepectorally placed implant than in those who underwent subpectoral immediate breast reconstruction. All patients reconstructed using the subpectoral technique had some degree of BAD. The inter- and intraobserver agreements were high when using the NSE grading scale, suggesting it is an easy-to-use, reproducible scale for assessing BAD in women who undergo immediate breast reconstruction.

The use of mesh for immediate breast reconstruction was introduced almost two decades ago. Lately, the number of prepectoral direct to implant breast reconstructions has increased as this technique seems to leave an unimpaired muscle function and may lead to less or no breast animation deformity (BAD) and quicker recovery. However, challenges still remain as there is a risk of thin tissue coverage, visible implant edges and secondary ptosis. In this visualized surgery paper, we visualize the technical disparities between the sub- and prepectoral direct to implant breast reconstruction., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare., (2019 Gland Surgery.

In this visualized surgery paper, we present our experience identifying the optimal dissection plane in nipple-sparing mastectomy using hydrodissection through an inframammary incision. The surgical technique comprises of preoperative magnetic resonance imaging (MRI) aiming to assess the thickness and expected quality of the mastectomy flaps, an inframammary incision, and hydrodissection to assist the surgeon in identifying the optimal dissection plane. This surgical method results in an adequate resection of breast parenchyma to obtain the best oncological outcome, while retaining the maximum amount of subcutaneous adipose tissue on the skin flaps to achieve a superior aesthetic result resembling the natural breast. The mastectomy flap thickness and quality can then be assessed prior to an immediate reconstruction., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare., (2019 Gland Surgery.

Thoracodorsal artery perforator (TAP) flaps are versatile flaps that provide a consistent and aesthetically pleasing breast reconstruction. We prefer the TAP flap to the latissimus dorsi (LD) flap due to the morbidity associated with the LD flap. In this paper we aim to show how we perform bilateral TAP flap breast reconstruction and present our preliminary results from 32 bilateral reconstructions in 16 patients. The TAP flap breast reconstruction can be performed as a direct-to-implant or a delayed procedure depending on patient factors. Color Doppler ultrasonography (CDU) is used in the preoperative planning which promotes the safety and reliability of the flap by mapping perforators thus enabling faster dissection. The bilateral TAP flap breast reconstruction is usually performed in three steps: (I) raising the flaps at the recipient site; (II) rotating the TAP flaps and (III) completion of the breast reconstruction., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare., (2019 Gland Surgery.

The number of patients in need of a mastopexy with autologous augmentation after massive weight loss (MWL) increases along with the increasing number of bariatric surgeries. The primary aim of this paper was to visualize how we utilize the lateral excess of the breast for auto augmentation. The secondary aim was to assess the outcome using the LOPOSAM technique in a larger study population. This retrospective study included 72 MWL patients aged 40±9 years undergoing a bilateral LOPOSAM procedure, between March 2015 and April 2018. All patients had undergone a weight loss of more than 15 BMI units, had a BMI of less than 30 kg/m 2 at the time of surgery and functional problems due to excess or lax skin. Patient demographics, comorbidities, cause of MWL, operative time and complications were recorded. The mean weight loss was 58±18 kg or 21±6 BMI units. The mean operative time was 97±39 minutes. The surgical goal was achieved in all patients. Three patients (4%) experienced hematomas requiring surgical intervention. The utilization of the lateral excess of the breast for auto augmentation in MWL patients is visualized. The long term results using the LOPOSAM mastopexy technique shows that the technique is quick, safe and with a low rate of complications., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare., (2019 Gland Surgery.

Background: Inguinal lymphadenectomy (ILND) for melanoma is associated with a number of complications including seroma, surgical site infection (SSI), and lymphedema. Incisional negative pressure wound therapy (iNPWT) has shown promising results in preventing postoperative morbidity across a wide variety of surgical procedures, but these results are yet to be investigated in patients undergoing ILND for melanoma., Methods: In this study, we reviewed the data of 55 melanoma patients treated with ILND between January 2015 and January 2017 at Odense University Hospital. Patients were followed up until April 2018 for the occurrence of seroma, SSI, and lymphedema. We used prophylactic iNPWT after ILND in 14 patients and compared their morbidity outcomes with the 41 patients receiving standard postoperative wound care in the same period., Results: The iNPWT intervention significantly reduced seroma compared to the control group (28.6% vs. 90.3%, p < 0.001) and had a trending impact on wound infection (42.9% vs. 65.9%, p = 0.13). The effect was not significant for the prevention of lymphedema (35.7% vs. 51.2%, p = 0.33). Because the iNPWT group had relatively fewer incidences of seroma, SSI, and lymphedema, the iNPWT intervention was more cost-effective than conventional wound care (US$911.2 vs. US$2542.7, p < 0.05)., Conclusion: The use of prophylactic iNPWT significantly reduced seroma formation following ILND. These promising results, however, need to be confirmed in a future prospective randomized trial., (Copyright © 2019 Elsevier Ltd. All rights reserved.)

Surface Guided Radiotherapy (SGRT) is a relatively new technique for positioning patients and for monitoring patient movement during treatment. SGRT is completely non-invasive since it uses visible light for determining the position of the patient surface. A reduction in daily imaging for patient setup is possible if the accuracy of SGRT is comparable to imaging. It allows for monitoring of intrafraction motion and the radiation beam can be held beyond a certain threshold resulting in a more accurate irradiation. The purpose of this study was to investigate setup uncertainty and the intrafraction motion in non-gated whole breast cancer radiotherapy treatment using an integrated implementation of AlignRT (OSMS) system as SGRT. In initial setup, SGRT was compared to three-point setup using tattoos on the patient and orthogonal kV imaging. For the investigation of intrafraction motion, OSMS monitored the patient with six degrees of freedom during treatment. Using three-point setup resulted in a setup root-mean-square error from the isocenter of 5.4 mm. This was improved to 4.2 mm using OSMS. For the translational directions, OSMS showed improvements in the lateral direction (P = 0.0009, Wilcoxon rank-sum), but for the longitudinal direction and rotation it was not possible to show improvements (P = 0.96 and P = 0.46, respectively). The vertical direction proved more accurate for three-point setup than OSMS (P = 0.000004). Intrafraction motion was very limited with a translational median of 1.1 mm from the isocenter. While OSMS showed marked improvements over laser and tattoo setup, the system did not prove accurate enough to replace the daily orthogonal kV images aligned to bony anatomy., (© 2019 The Authors.
