Purpose: Coloanal anastomosis with loop diverting ileostomy (CAA) is an option for low anterior resection of the rectum, and Turnbull-Cutait coloanal anastomosis (TCA) regained popularity in the effort to offer patients a reconstructive option. In this context, we aimed to compare both techniques., Methods: PubMed, Cochrane, and Scopus were searched for studies published until January 2024. Odds ratios (RRs) with 95% confidence intervals (CIs) were pooled with a random-effects model. Statistical significance was defined as p < 0.05. Heterogeneity was assessed using the Cochran Q test and I 2 statistics, with p-values inferior to 0.10 and I 2 >25% considered significant. Statistical analysis was conducted in RStudio version 4.1.2 (R Foundation for Statistical Computing). Registered number CRD42024509963., Results: One randomized controlled trial and nine observational studies were included, comprising 1,743 patients, of whom 899 (51.5%) were submitted to TCA and 844 (48.5%) to CAA. Most patients had rectal cancer (52.2%), followed by megacolon secondary to Chagas disease (32.5%). TCA was associated with increased colon ischemia (OR 3.54; 95% CI 1.13 to 11.14; p < 0.031; I 2 = 0%). There were no differences in postoperative complications classified as Clavien-Dindo ≥ IIIb, anastomotic leak, pelvic abscess, intestinal obstruction, bleeding, permanent stoma, or anastomotic stricture. In subgroup analysis of patients with cancer, TCA was associated with a reduction in anastomotic leak (OR 0.55; 95% CI 0.31 to 0.97 p = 0.04; I 2 = 34%)., Conclusion: TCA was associated with a decrease in anastomotic leak rate in subgroups analysis of patients with cancer., (© 2024.

Intra-abdominal desmoid tumors are a rare and complex clinical problem. These tumors are locally invasive, and surgical ablation represents the mainstay of treatment. When localized at the root of the mesentery, their resection may require extensive excision of the intestine resulting in intestinal failure and life-long total parenteral nutrition. Intestinal transplantation, either autotransplantation or allotransplantation, has been used as a viable option to treat this group of patients. Herein, we describe a series of 4 patients with unresectable intra-abdominal desmoid tumor who underwent cadaveric isolated intestinal and ascending colon transplantation., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2024 Pierpaolo Di Cocco et al.)

The primary objective of this study was to compare short-term outcomes between Intracorporeal ileocolic anastomosis (IIA) and extracorporeal ileocolic anastomosis (EIA) after laparoscopic right hemicolectomy in patients with visceral obesity. The secondary objective was to identify risk factors associated with prolonged postoperative ileus (PPOI) after laparoscopic right hemicolectomy. This single-center retrospective study analyzed visceral obesity patients who underwent laparoscopic right hemicolectomy for primary bowel cancer between January 2020 and June 2023. Patients were categorized into IIA and EIA groups based on the type of anastomosis, and a 1:1 propensity score-matched analysis was performed. A total of 129 patients were initially included in this study, with 45 patients in each group following propensity score matching. The IIA group had significantly longer anastomosis times (p < 0.001), shorter incision length (p < 0.001), and shorter length of stay (p = 0.003) than the EIA group. Meanwhile, the IIA group showed a shorter time to first flatus (p = 0.044) and quicker tolerance of a solid diet (p = 0.030). On multivariate analysis, postoperative use of opioid analgesics is an independent risk factor for PPOI (OR: 3.590 95% CI 1.033-12.477, p = 0.044), while IIA is an independent protective factor (OR: 0.195 95% CI 0.045-0.843, p = 0.029). IIA remains a safe and feasible option for visceral obesity patients. It is also associated with a quicker recovery of bowel function and shorter length of stay when compared to EIA. Additionally, IIA is an independent protective factor for PPOI., (© 2024. The Author(s).)

Background: Although minimally invasive surgery for Crohn's disease has been validated in previous studies, most of those reports have referred to laparoscopic-assisted procedures with an extra-corporeal anastomosis., Objectives: To evaluate the short- and long-term outcomes of total laparoscopic ileocolic resection with an intracorporeal anastomosis for Crohn's disease patients., Methods: We conducted a single-center retrospective review of all patients who underwent primary ileocolic resection for Crohn's disease between 2010 and 2021. Group A included 34 patients who underwent total laparoscopic ileocolic resection with intracorporeal anastomosis. Group B comprised 144 patients who underwent an open or laparoscopic-assisted procedure., Results: No differences were noted in operative time (mean 167 minutes vs. 152 minutes, P = 0.122), length of stay (median 6.4 days vs. 7.5 days, P = 0.135), readmission rates (11.8% vs. 13.2%, P = 1), and microscopic involvement of surgical margins (7.7% vs. 18.5%, P = 0.249). Group A had significantly fewer postoperative surgical site infections (2.9% vs. 22.2% respectively, P = 0.013), with no differences in other complications prevalence. After a median follow-up of 46 months, there were similar rates of endoscopic recurrence (47.1% vs. 51.4%, P = 0.72), clinical recurrence (35.3% vs. 47.9%, P = 0.253), and surgical recurrence (2.9% vs. 4.9%, P = 0.722)., Conclusions: Total laparoscopic ileocolic resection with intracorporeal anastomosis for Crohn's disease is safe and resulted in favorable outcomes in terms of postoperative wound healing. The long-term disease recurrence rates were like those of laparoscopic-assisted and open ileocolic resection.

Colorectal anastomotic leakage (CAL) remains a feared complication after colorectal surgery and requires prompt detection and proper treatment. With the upswing of fast-track recovery programs in recent years this challenge has increased, as clinical features may only arise after discharge. Therefore, identification of the best diagnostic tools is of utmost importance, also since early treatment is associated with high success rates. Diagnostic tools range from general screening tools to invasive procedures to assess the severity of the leak. Laboratory tests, in particular the inflammation biomarkers C-reactive protein and procalcitonin, have a significant role in the detection of CAL after colorectal surgery. As these biomarkers are unspecific for CAL, additional imaging should be performed when blood levels are elevated. The golden standard for the detection of AL after colonic resections is a computed tomography (CT-scan). If tolerated, a contrast medium should be administered rectally to enhance diagnostic accuracy. When suspicion of CAL remains high despite negative previous tests, further endoscopy examination should be conducted. However, endoscopic examinations become more suitable for the early diagnostic work-up after rectal resections. This review aims to provide an overview of current diagnostics for the screening and assessment of the severity of CAL after colorectal surgery., Competing Interests: Declaration of competing interest The authors declare that they have no conflict of interest., (Copyright © 2024.

Background: Our aim was to describe the clinical outcomes of surgical interventions performed for the management of colonoscopy-related perforations and to compare these outcomes with those of matched colorectal surgeries performed in elective and emergency settings., Methods: We included patients with endoscopic colonic perforation who underwent surgical intervention from the 2014-2017 National Surgery Quality Improvement Program participant use data colorectal targeted procedure file. The primary outcome in this study was short term surgical morbidity and mortality. Patients (group 1) were matched with 1:2 ratio to control patients undergoing same surgical interventions for other indications on an elective (group 2) or emergency basis (group 3). Bivariate analysis was conducted to compare categorical variables between the three groups, and multivariate logistic regression was used to evaluate the association between the surgical indication and 30-day postoperative outcomes., Results: A total of 590 patients were included. The average age of the patients was 66.5±13.6 with female gender predominance (381, 64.6%) The majority of patients underwent open colectomy (365, 61.9%) while the rest had suturing (140, 23.7%) and laparoscopic colectomy (85, 14.4%). Overall mortality occurred in 4.1% and no statistically significant difference in mortality was found between the three techniques (P=0.468). Composite morbidity occurred in 163 patients (27.6%). It was significantly lower in laparoscopic colectomy (14.1%) compared to 30.2% and 29.4% in open colectomy and suturing approaches (P=0.014). Patients undergoing colectomy for iatrogenic colonic perforation had less mortality, infection rates and sepsis, as well as bleeding episodes compared to those who had colectomy on an emergent basis. Outcomes were comparable between the former group and patients undergoing elective colectomy for other indications., Conclusions: Surgical management of colonoscopy related perforations is safe and effective with outcomes that are similar to that of patients undergoing elective colectomy.

Background: Delayed gastric emptying (DGE) is a common complication after pancreaticoduodenectomy. There remains an active debate over the effect of gastrointestinal (GI) reconstruction techniques, such as antecolic (AC) or transmesocolic (TMC) reconstruction, on DGE rates. This study compared the rates of DGE between AC reconstruction and TMC reconstruction after pylorus-preserving pancreaticoduodenectomy (PPPD) and classic pancreaticoduodenectomy (PD)., Methods: This was a retrospective analysis of a prospectively maintained pancreatic surgery database in a single, high-volume center. Demographic, perioperative, and surgical outcome data were recorded from patients who underwent a PD or PPPD between 2013 and 2021. DGE grades were classified using the International Study Group of Pancreatic Surgeons (ISGPS) criteria. Postoperatively, all patients were managed using an accelerated Whipple recovery protocol., Results: A total of 824 patients were assessed, with 303 patients undergoing AC reconstruction and 521 patients undergoing TMC reconstruction. The risk of DGE was significantly greater in patients who received an AC reconstruction than in patients who received a TMC reconstruction (odds ratio [OR], 1.51; 95% CI, 1.07-2.15; P < .05). In addition, AC reconstruction was shown to have a greater incidence of severe DGE (ISGPS grades B or C) than TMC reconstruction, with approximately a 2-fold increase in severe DGE (OR, 1.94; 95% CI, 1.10-3.45; P < .05). Logistic regression and propensity score matching have found increased DGE incidence with AC reconstruction (OR: 1.69 and 1.73, respectively; P < .05)., Conclusions: Although the correlation between GI reconstruction methods and DGE remains a subject of ongoing debate, our study indicated that TMC reconstruction may be superior to AC reconstruction in minimizing the development and severity of DGE for patients after PD., Competing Interests: Declaration of Competing Interest The authors declare no competing interests., (Copyright © 2024 Society for Surgery of the Alimentary Tract.

Colorectal cancer, the third most common cancer worldwide, affects 40-45% of patients on the right side. Surgery, especially minimally invasive methods such as laparoscopic and robotic procedures, is the preferred treatment. However, these techniques present technical complications. The anatomical complexity and variations in vessel branching patterns pose challenges, particularly for less experienced surgeons. The CoDIG 2 is a nationwide observational study involving 76 specialized Italian general surgery departments focused on colorectal surgery. The centres were directed to maintain their standard surgical and clinical practices. The aim of this study was to analyse the intraoperative vascular anatomy of Italian patients who underwent laparoscopic right colectomy and explore the ligature techniques used by Italian surgeons. Surgeons reported information about vascularization of the right colon for 616 patients and about surgical anatomy of RCA for 368 patients. Fifty-three patients (10.8%) showed no RCA intraoperatively. The right colic artery (RCA) was categorized according to the Yada classification (types 1-4) during evaluation, and intraoperative assessments revealed that Yada type 1 was the most common type (55.2%), while radiologic evaluations revealed a higher prevalence of type 2. Furthermore, compared with the superior mesenteric vein (SMV), the RCA is more often located anteriorly according to intraoperative and contrast-enhanced CT examination; 59.9% were found in the anterior position during intraoperative examination, while 40.1% were found in the same position on preoperative contrast-enhanced CT. Vascularization of the right colon, including missing branches, additional branches, shared trunks, and retro-superior courses of the mesenteric vein, exhibited notable variations. To understand vascular variations, a preoperative radiological study is necessary; although there was no concordance between the intraoperative and radiological evaluations, this is a limitation of preinterventional radiological evaluation (PII) because it is always needed for oncological staging. This approach is especially critical for inexperienced surgeons to avoid potential complications, such as problematic bleeding., (© 2024. The Author(s).)

Purpose: The surgical approach to bowel endometriosis is still unclear. The aim of the study is to compare TICA to conventional specimen extractions and extra-abdominal insertion of the anvil in terms of both complications and functional outcomes., Methods: This is a single-center, observational, retrospective study conducted enrolling symptomatic women underwent laparoscopic excision of deep endometriosis with segmental bowel resection between September 2019 and June 2022. Women who underwent TICA were compared to classical technique (CT) in terms of intra- and postoperative complications, moreover, functional outcomes relating to the pelvic organs were assessed using validated questionnaires [Knowles-Eccersley-Scott-Symptom (KESS) questionnaire and Gastro-Intestinal Quality of Life Index (GIQLI)] for bowel function. Pain symptoms were assessed using Visual Analogue Scale (VAS) scores., Results: The sample included 64 women. TICA was performed on 31.2% (n = 20) of the women, whereas CT was used on 68.8% (n = 44). None of the patients experienced rectovaginal, vesicovaginal, ureteral or vesical fistula, or ureteral stenosis and uroperitoneum, and in no cases was it necessary to reoperate. Regarding the two surgical approaches, no significant difference was observed in terms of complications. As concerns pain symptoms at 6-month follow-up evaluations on stratified data, except for dysuria, all VAS scales reported showed significant reductions between median values, for both surgery interventions. As well, significant improvements were further observed in KESS scores and overall GIQLI. Only the GIQLI evaluation was significantly smaller in the TICA group compared to CT after the 6-month follow-up., Conclusions: We did not find any significant differences in terms of intra- or post-operative complications compared TICA and CT, but only a slight improvement in the Gastro-Intestinal Quality of Life Index in patients who underwent the CT compared to the TICA technique., (© 2024.

Postoperative ileus (POI) after colorectal surgery is a major problem that affects both patient recovery and hospital costs highlighting the importance of preventive strategies. Therefore, we aimed to perform a systematic analysis of the effects of postoperative caffeine consumption on bowel recovery and surgical morbidity after colorectal surgery. A comprehensive literature search was conducted through September 2023 for randomized and non-randomized trials comparing the effect of caffeinated versus non-caffeinated drinks on POI by evaluating bowel movement resumption, time to first flatus and solid food intake, and length of hospital stay (LOS). Secondary outcome analysis included postoperative morbidity in both groups. After data extraction and inclusion in a meta-analysis, odds ratios (ORs) for dichotomous variables and standardized mean differences (SMDs) for continuous outcomes with 95% confidence intervals (CIs) were calculated. Subgroup analyses were performed in cases of substantial heterogeneity. Six randomized and two non-randomized trials with a total of 610 patients were included in the meta-analysis. Caffeine intake significantly reduced time to first bowel movement [SMD -0.39, (95% CI -0.66 to -0.12), p = 0.005] and time to first solid food intake [SMD -0.41, (95% CI -0.79 to -0.04), p = 0.03] in elective laparoscopic colorectal surgery, while time to first flatus, LOS, and the secondary outcomes did not differ significantly. Postoperative caffeine consumption may be a reasonable strategy to prevent POI after elective colorectal surgery. However, larger randomized controlled trials (RCTs) with homogeneous study protocols, especially regarding the dosage form of caffeine and coffee, are needed., (© 2024. The Author(s).)

Objectives: Abnormal motility of the residual colon has been reported in post-pull-through Hirschsprung disease (PT-HSCR) patients with persistent defecation problems. We reviewed the role of colonic manometry (CM) in the management of defecation disorders in these patients., Methods: We retrospectively reviewed the medical record of PT-HSCR children who underwent CM for persistent symptoms of abnormal defecation. We reviewed their clinical course and its relation to CM findings., Results: Thirty PT-HSCR patients underwent CM, of which five were diagnosed with transition zone pull-through and were excluded. Of the remaining 25 patients, 16 had colonic dysmotility, 8 had normal CM, and one had colonic hypermotility. In patients with dysmotility, five responded to ongoing medical management, three required surgical intervention (ileostomy), three remained symptomatic with medical management but not yet received surgical intervention, and five were lost to follow-up. In patients with normal CM, four responded to ongoing medical therapy, two required additional surgery (antegrade enema procedure), and two were lost to follow-up. The patient with hypermotility improved with adding loperamide., Conclusions: Colonic dysmotility can occur in PT-HSCR patients with persistent defecation problems. CM was helpful in delineating the degree of colonic neuromuscular dysfunction. CM results were used in conjunction with other clinical data to determine optimal management. Our findings support that medical management should first be optimized before consideration of colonic manometry and surgical interventions., (© 2024 European Society for Pediatric Gastroenterology, Hepatology, and Nutrition and North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition.)

Background: Left-sided colorectal surgery demonstrates high anastomotic leak rates, with tissue ischemia thought to influence outcomes. Indocyanine green is commonly used for perfusion assessment, but evidence remains mixed for whether it reduces colorectal anastomotic leaks. Laser speckle contrast imaging provides dye-free perfusion assessment in real-time through perfusion heat maps and quantification., Objective: This study investigates the efficacy of advanced visualization (indocyanine green versus laser speckle contrast imaging), perfusion assessment, and utility of laser speckle perfusion quantification in determining ischemic margins., Design: Prospective intervention group using advanced visualization with case-matched, retrospective control group., Settings: Single academic medical center., Patients: Forty adult patients undergoing elective, minimally invasive, left-sided colorectal surgery., Interventions: Intraoperative perfusion assessment using white light imaging and advanced visualization at 3 time points: T1-proximal colon after devascularization, before transection, T2-proximal/distal colon before anastomosis, and T3-completed anastomosis., Main Outcome Measures: Intraoperative indication of ischemic line of demarcation before resection under each visualization method, surgical decision change using advanced visualization, post hoc laser speckle perfusion quantification of colorectal tissue, and 30-day postoperative outcomes., Results: Advanced visualization changed surgical decision-making in 17.5% of cases. For cases in which surgeons changed a decision, the average discordance between the line of demarcation in white light imaging and advanced visualization was 3.7 cm, compared to 0.41 cm ( p  = 0.01) for cases without decision changes. There was no statistical difference between the line of ischemic demarcation using laser speckle versus indocyanine green ( p  = 0.16). Laser speckle quantified lower perfusion values for tissues beyond the line of ischemic demarcation while suggesting an additional 1 cm of perfused tissue beyond this line. One (2.5%) anastomotic leak occurred in the intervention group., Limitations: This study was not powered to detect differences in anastomotic leak rates., Conclusions: Advanced visualization using laser speckle and indocyanine green provides valuable perfusion information that impacts surgical decision-making in minimally invasive left-sided colorectal surgeries.

El verde de indocianina se utiliza habitualmente para evaluar la perfusión, pero la evidencia sobre si reduce las fugas anastomóticas colorrectales sigue siendo contradictoria. Las imágenes de contraste moteado con láser proporcionan una evaluación de la perfusión sin colorantes en tiempo real a través de mapas de calor de perfusión y cuantificación.OBJETIVO:Este estudio investiga la eficacia de la evaluación de la perfusión mediante visualización avanzada (verde de indocianina versus imágenes de contraste moteado con láser) y la utilidad de la cuantificación de la perfusión con moteado láser para determinar los márgenes isquémicos.DISEÑO:Grupo de intervención prospectivo que utiliza visualización avanzada con un grupo de control retrospectivo de casos emparejados.LUGARES:Centro médico académico único.PACIENTES:Cuarenta pacientes adultos sometidos a cirugía colorrectal electiva, mínimamente invasiva, del lado izquierdo.INTERVENCIONES:Evaluación de la perfusión intraoperatoria mediante imágenes con luz blanca y visualización avanzada en tres puntos temporales: T1-colon proximal después de la devascularización, antes de la transección; T2-colon proximal/distal antes de la anastomosis; y T3-anastomosis completa.PRINCIPALES MEDIDAS DE VALORACIÓN:Indicación intraoperatoria de la línea de demarcación isquémica antes de la resección bajo cada método de visualización, cambio de decisión quirúrgica mediante visualización avanzada, cuantificación post-hoc de la perfusión con láser moteado del tejido colorrectal y resultados posoperatorios a los 30 días.RESULTADOS:La visualización avanzada cambió la toma de decisiones quirúrgicas en el 17,5% de los casos. Para los casos en los que los cirujanos cambiaron una decisión, la discordancia promedio entre la línea de demarcación en las imágenes con luz blanca y la visualización avanzada fue de 3,7 cm, en comparación con 0,41 cm (p = 0,01) para los casos sin cambios de decisión. No hubo diferencias estadísticas entre la línea de demarcación isquémica utilizando láser moteado versus verde de indocianina (p = 0,16). El moteado con láser cuantificó valores de perfusión más bajos para los tejidos más allá de la línea de demarcación isquémica y al mismo tiempo sugirió 1 cm adicional de tejido perfundido más allá de esta línea. Se produjo una fuga anastomótica (2,5%) en el grupo de intervención.LIMITACIONES:Este estudio no tuvo el poder estadístico suficiente para detectar diferencias en las tasas de fuga anastomótica.CONCLUSIONES:La visualización avanzada utilizando moteado láser y verde de indocianina proporciona información valiosa sobre la perfusión que impacta la toma de decisiones quirúrgicas en cirugías colorrectales mínimamente invasivas del lado izquierdo.

Introduction: Intraoperative indocyanine green fluorescence angiography (ICGFA) aims to reduce colorectal anastomotic complications. However, signal interpretation is inconsistent and confounded by patient physiology and system behaviours. Here, we demonstrate a proof of concept of a novel clinical and computational method for patient calibrated quantitative ICGFA (QICGFA) bowel transection recommendation., Methods: Patients undergoing elective colorectal resection had colonic ICGFA both immediately after operative commencement prior to any dissection and again, as usual, just before anastomotic construction. Video recordings of both ICGFA acquisitions were blindly quantified post hoc across selected colonic regions of interest (ROIs) using tracking-quantification software and computationally compared with satisfactory perfusion assumed in second time-point ROIs, demonstrating 85% agreement with baseline ICGFA. ROI quantification outputs detailing projected perfusion sufficiency-insufficiency zones were compared to the actual surgeon-selected transection/anastomotic construction site for left/right-sided resections, respectively. Anastomotic outcomes were recorded, and tissue lactate was also measured in the devascularised colonic segment in a subgroup of patients. The novel perfusion zone projections were developed as full-screen recommendations via overlay heatmaps., Results: No patient suffered intra- or early postoperative anastomotic complications. Following computational development (n = 14) the software recommended zone (ROI) contained the expert surgical site of transection in almost all cases (Jaccard similarity index 0.91) of the nine patient validation series. Previously published ICGFA time-series milestone descriptors correlated moderately well, but lactate measurements did not. High resolution augmented reality heatmaps presenting recommendations from all pixels of the bowel ICGFA were generated for all cases., Conclusions: By benchmarking to the patient's own baseline perfusion, this novel QICGFA method could allow the deployment of algorithmic personalised NIR bowel transection point recommendation in a way fitting existing clinical workflow., (© 2024.

Aim: Although proximal faecal diversion is standard of care to protect patients with high-risk colorectal anastomoses against septic complications of anastomotic leakage, it is associated with significant morbidity. The Colovac device (CD) is an intraluminal bypass device intended to avoid stoma creation in patients undergoing low anterior resection. A preliminary study (SAFE-1) completed in three European centres demonstrated 100% protection of colorectal anastomoses in 15 patients, as evidenced by the absence of faeces below the CD. This phase III trial (SAFE-2) aims to evaluate the safety and effectiveness of the CD in a larger cohort of patients undergoing curative rectal cancer resection., Methods: SAFE-2 is a pivotal, multicentre, prospective, open-label, randomized, controlled trial. Patients will be randomized in a 1:1 ratio to either the CD arm or the diverting loop ileostomy arm, with a recruitment target of 342 patients. The co-primary endpoints are the occurrence of major postoperative complications within 12 months of index surgery and the effectiveness of the CD in reducing stoma creation rates. Data regarding quality of life and patient's acceptance and tolerance of the device will be collected., Discussion: SAFE-2 is a multicentre randomized, control trial assessing the efficacy and the safety of the CD in protecting low colorectal anastomoses created during oncological resection relative to standard diverting loop ileostomy., Trial Registration: NCT05010850., (© 2024 Association of Coloproctology of Great Britain and Ireland.)

Carl Florian Toldt was an Austrian anatomist who made meaningful contributions worldwide and defined what is one of the most important surgical landmarks in abdominal surgery. Through his research studies, the embryologic dissection plane known as the "White Line of Toldt" represents an important anatomical landmark that helps to mobilize either the ascending or descending colon. His career spanned over 45 years, beginning in Verona and continuing to Prague and Vienna. He was an author of several innovative books and scientific articles regarding micro- and macroscopic anatomy. In addition, he received numerous recognitions and prizes for his work, making him an essential figure in the medical scientific community. Even a street in Vienna, Karl-Toldt-Weg, is named in his honor. The purpose of this historical article is to celebrate and honor Toldt 100 years following his death, remembering his scientific contributions to the medical and surgical fields and giving thanks for his numerous accomplishments. This article brings light to the man behind the eponym. [ABSTRACT FROM AUTHOR]

Background: Both wound infiltration (WI) with local anaesthetic and Erector Spinae Plane block (ESPB) have been described for post-operative analgesia after abdominal surgery. This study compared the efficacy of WI versus ESPB for post-operative analgesia after laparoscopic assisted colonic surgery. Methods: Seventy-two patients between 18 and 85 years of age undergoing elective surgery were randomised to receive either WI or ESPB. In the WI group a 40 ml bolus of 0.5% Ropivacaine, infiltrated at the ports and minimally invasive wound at subcutaneous and fascia layers. In the ESPB group at T8 level, under ultrasound guidance, a 22-gauge nerve block needle was passed through the Erector Spinae muscle to reach its fascia. A dose up to 40 ml of 0.5% Ropivacaine, divided into two equal volumes, was injected at each side. Both groups had a multimodal analgesic regime, including regular Paracetamol, dexamethasone and patient-controlled analgesia (PCA) with Fentanyl. The primary end point was a post-operative pain score utilising a verbal Numerical Rating Score (NRS, 0–10) on rest and coughing in the post anaesthetic care unit (PACU) and in the first 24 h. Secondary outcomes measured were: opioid usage, length of stay and any clinical adverse events. Results: There was no significant treatment difference in PACU NRS at rest and coughing (p-values 0. 382 and 0.595respectively). Similarly, there were no significant differences in first 24 h NRS at rest and coughing (p-values 0.285 and 0.431 respectively). There was no significant difference in Fentanyl use in PACU or in the first 24 h (p- values 0.900 and 0.783 respectively). Neither was there a significant difference found in mean total Fentanyl use between ESPB and WI groups (p-value 0.787). Conclusion: Our observations found both interventions had an overall similar efficacy. Trial registration: The study was registered with the Australian New Zealand Clinical Trial Registry (ACTRN: 12619000113156). [ABSTRACT FROM AUTHOR]

Background: Incomplete resection of neoplastic polyps is considered an important reason for the development of colorectal cancer. However, there are no data on the natural history of polyps that were incompletely removed.Objective: To examine the risk for metachronous neoplasia during surveillance colonoscopy after documented incomplete polyp resection.Design: Observational cohort study of patients who participated in the CARE (Complete Adenoma REsection) study (2009 to 2012).Setting: 2 academic medical centers.Patients: Patients who had resection of a 5- to 20-mm neoplastic polyp, had a documented complete or incomplete resection, and had a surveillance examination.Measurements: Segment metachronous neoplasia, defined as the proportion of colon segments with at least 1 neoplastic polyp at first surveillance examination, was measured. Segment metachronous neoplasia was compared between segments with a prior incomplete polyp resection (incomplete segments) and those with a prior complete resection (complete segments), accounting for clustering of segments within patients.Results: Of 233 participants in the original study, 166 (71%) had at least 1 surveillance examination. Median time to surveillance was shorter after incomplete versus complete resection (median, 17 vs. 45 months). The risk for any metachronous neoplasia was greater in segments with incomplete versus complete resection (52% vs. 23%; risk difference [RD], 28% [95% CI, 9% to 47%]; P = 0.004). Incomplete segments also had a greater number of neoplastic polyps (mean, 0.8 vs. 0.3; RD, 0.50 [CI, 0.1 to 0.9]; P = 0.008) and greater risk for advanced neoplasia (18% vs. 3%; RD, 15% [CI, 1% to 29%]; P = 0.034). Incomplete resection was the strongest independent factor associated with metachronous neoplasia (odds ratio, 3.0 [CI, 1.12 to 8.17]).Limitation: Potential patient selection bias due to incomplete follow-up.Conclusion: This natural history study found a statistically significantly greater risk for future neoplasia and advanced neoplasia in colon segments after incomplete resection compared with segments with complete resection.Primary Funding Source: None.

Intestinal diffuse ganglioneuromatosis is a rare, benign, neoplastic condition characterized by disseminated proliferation of neural elements. It has an established association with several systemic disorders including: multiple endocrine neoplasia IIB (MEN IIB) and von Recklinghausen's disease. However, isolated GNs are very rare and sporadic. We report a case of a 6-year-old patient was referred to the emergency department due to a colon perforation during endoscopy. He then underwent sigmoidectomy and the pathologic studies revealed prominent signs of diffuse ganglioneuromatosis. Unfortunately, the patient died the day after because of the late diagnosis and treatment. Such presentation emphasizes the importance of considering diffuse ganglioneuromatosis, among other causes, in patients with intractable GI symptoms despite medical treatment. [ABSTRACT FROM AUTHOR]

Purpose: Intraoperative estimated blood loss (EBL) is often reported in nearly all surgical papers; however, there is no consensus regarding its measurement. The aim of this study was to determine whether EBL (ml) is as reliable and reproducible in predicting complications as a simple binary grading of EBL. Methods: All consecutive patients undergoing colectomies between January 2015 and December 2018 were included. EBL was assessed prospectively by the surgeon and anaesthesiologist in ml and with a binary scale: bleeding "as usual" versus "more than usual" by the surgeon. Differences between pre- and post-operative haemoglobin levels (ΔHb g/dl) were correlated to EBL. Blood loss impact on 30-day postoperative morbidity was analysed. Results: A total of 270 patients were included, with a mean age of 65 years (SD 17). Mean EBL documented by surgeons correlated to EBL by anaesthesiologists (79.5 ml, SD 99 vs. 84.5 ml, SD 118, ϱ = 0.926, p < 0.001). Surgeons and anaesthesiologists' EBL correlated also with ΔHb (ϱ = − 0.273, p = 0.01 and ϱ = − 0.344, p = 0.01, respectively). Patient with surgeon EBL ≥ 250 ml or graded as "more than usual" bleeding had significantly more severe complications (8% vs. 20%, p = 0.02 and 8% vs. 27%, p = 0.001, respectively). Conclusion: Anaesthesiologist and surgeon's EBL correlated with ΔHb. Simple grading of blood loss as "usual" and "more than usual" predicted severe complications and higher mortality rates. This simple binary grading of blood loss in colon surgery could be an alternative to the estimation of blood loss in ml as it is easy to apply but needs to be validated externally.

Background: Management of bowel traumatic injuries is a challenge. Although anastomotic or suture leak remains a feared complication, preserving bowel continuity is increasingly the preferred strategy. The aim of this study was to evaluate the outcomes of such a strategy.Methods: All included patients underwent surgery for bowel traumatic injuries at a high volume trauma center between 2007 and 2017. Postoperative course was analyzed for abdominal complications, morbidity and mortality.Results: Among 133 patients, 78% had small bowel injuries and 47% had colon injuries. 87% of small bowel injuries and 81% of colon injuries were treated with primary repair or anastomosis, with no difference in treatment according to injury site (p = 0.381). Mortality was 8%. Severe overall morbidity was 32%, and abdominal complications occurred in 32% of patients. Risk factors for severe overall morbidity were stoma creation (p = 0.036), heavy vascular expansion (p = 0.005) and a long delay before surgery (p = 0.023). Fistula rate was 2.2%; all leaks occurred after repairing small bowel wounds.Conclusion: Primary repair of bowel injuries should be the preferred option in trauma patient, regardless of the site-small bowel or colon-of the injury. Stoma creation is an important factor for postoperative morbidity, which should be weighed against the risk of an intestinal suture or anastomosis. [ABSTRACT FROM AUTHOR]

Ileal/colon conduit, cutaneous continent diversion, and orthotopic neobladder surgeries are becoming increasingly common following cystectomy for bladder cancer and other situations that result in bladder removal. These surgeries are considered the most complex surgical procedures in the field of urology, with high complication rates. Postoperative care criteria for each surgery are unique and require the provider/nurse to be knowledgeable about the actual procedures, what part of the bowel was utilized, and assessment/care interventions that optimize outcomes for this vulnerable and often overlooked patient population. Additionally, understanding patient selection and contraindications for these procedures, as well as expectations, allows for the provider/nurse to better counsel and educate patients on potential options for care relative to their individual needs for a urinary diversion, as well as what they can anticipate postoperatively and as they resume their previous lifestyle with their urinary diversion.

Background: Standardized protocols for laparoscopic surgery of splenic flexure cancer (SFC) have not been established yet. We described a standardized laparoscopic procedure for SFCs and examined its safety and feasibility. Methods: Laparoscopic colectomy for SFC was performed as follows. The sigmoid colon was mobilized to the descending mesocolon through the medial approach. After confirming the base of the inferior mesenteric artery, the left colic artery was dissected and resected at the base. Further dissection was carried out between the mesentery of the colon and the renal fascia until it exceeded the upper pole of the left kidney and the splenic flexure. The next dissection reached the white line at the lateral side and the sigmoid-descending colon junction. After making an incision at the greater omentum and gastrocolic ligament from the center of the transverse colon to the splenic flexure, the transverse mesocolon base was dissected from the inside splenic flexure for complete mobilization. This was performed by approaching from four directions toward the splenic flexure. Intestinal resection and anastomosis are performed. Results: This procedure was performed in 70 patients with splenic flexure colon cancer (mean age 70 years). The mean operative time was 190 minutes, and the mean blood loss was 2.0 mL. No notable perioperative or postoperative complications were noted. Conclusions: Safe mobilization of the splenic flexure can be achieved by approaching from four directions, and standardization of left colectomy can facilitate complete mesenteric excision.

INTRODUCTION: An intrauterine contraceptive device (IUCD) is a common contraception method used for family planning. IUCD erosion into adjacent organs is a rare but serious complication of IUCD use. CASE PRESENTATION: A 41-year-old female presented to us with a leaking left ectopic pregnancy. Emergency laparotomy and left salpingectomy were performed. A copper ICUD was found intraperitoneally and part of it had completely eroded into the sigmoid colon. Sigmoid colotomy was performed and the IUCD was removed successfully. Further history revealed that the patient had her IUCD inserted 12 years previously but was forgotten. The patient was discharged well after 4 days of admission. DISCUSSION: Erosion of an IUCD into the colon is uncommon and may be asymptomatic or present with bowel perforation and obstruction. There should be a high index of suspicion for pregnancy occurring among women post-IUCD insertion. A misplaced IUCD can cause chronic inflammation of the fallopian tube, which may alter tubal functionality and increase the risk of ectopic pregnancy. Family planning is commonly done in primary health care. Primary care education and counselling are essential to improve awareness of fertile women to prevent similar complications. Periodic examination of IUCD string either by users or primary health-care practitioners is crucial. Ultrasound can be advocated if there are difficulties with the insertion. An abdominal radiograph is useful and should be performed in the case of missing IUCDs. [ABSTRACT FROM AUTHOR]

BackgroundThis study sought to compare outcomes of patients who underwent hand-assisted laparoscopic (HAL) colectomy with open and laparoscopic colectomy (LP).Study designThe NSQIP databases were used to examine the clinical data of patients who underwent elective colectomy during 2012-2013. Multivariate regression analysis was performed to compare the three surgical approaches.ResultsWe sampled a total of 21,090 patients who underwent colectomy. Of these, 7480 (35.5 %) had open colectomy (OC), 8751 (41.5 %) had a laparoscopic colectomy, 2860 (13.6 %) had a HAL colectomy, and 1999 (9.5 %) had an open procedure converted from LC or HAL. Multivariate regression analysis revealed HAL colectomy had a similar mortality (AOR 0.53, P = 0.07) and a lower morbidity (AOR 0.37, P

The article focuses on the ethical dimension of background care which is often overlooked but always present. Topics discussed include Ethical consideration in health care is often thought to be the application of specialized knowledge in exceptional situations; and Clinical ethics is traditionally taught by examining dilemma cases and identifying and assessing mutually exclusive actions, each of which has a valid ethical justification.

Background and aims: Deep venous thrombosis (DVT) is known to occur preferentially on the left lower extremity. The renowned surgeon Denis Burkitt advanced the theory that a heavy sigmoid colon would compress the left pelvic veins and predispose to DVT. Our study aimed to evaluate this hypothesis by comparing the laterality distributions with and without a prior colectomy. Methods: We conducted a retrospective analysis of the 2016 National Inpatient Sample database by stratifying the patients at any age with acute DVT of lower extremity by history of prior colectomy, thereby eliminating local gut mechanical factors in the development of DVT. We compared the laterality distribution (i.e., left, right, bilateral, and unspecified) between the patients with and without a prior colectomy. We also conducted a subgroup analysis by the sex category to examine the difference in laterality distribution for male and female patients. Chi-square test for independence was used. P value ≤0.05 was considered statistically significant. Results: We found an estimated total of 342,525 cases. Among patients without a prior colectomy, 136,605 (41.6%) were left-sided DVT versus 119,555 (36.4%) right-sided, with 55,555 bilateral and 16,865 unspecified. Among patients with a prior colectomy, 5,750 (41.2%) were left-sided, 5,000 (35.9%) were right-sided, 2,345 were bilateral and 850 were unspecified. The laterality distribution between the two groups was not significantly different (p =.167). The left-side predominance disappeared only in males with a prior colectomy (37.1% for left vs. 38.9% for right, p =.027). Conclusions: Our findings did not confirm the Burkitt's hypothesis. The left-side predominance of lower extremity DVT was attenuated only in male patients with a prior colectomy. [ABSTRACT FROM AUTHOR]

BACKGROUND : Clinically significant post-endoscopic bleeding (CSPEB) is a common complication following colonic endoscopic mucosal resection (EMR). Current prediction tools are clinical and do not use the appearance of the post-EMR mucosal defect. We aimed to predict CSPEB by analyzing blood vessel morphology within the post-EMR mucosal defect. METHODS : 43 patients with CSPEB were matched to 43 non-bleeders for clinical variables associated with CSPEB. Computerized image analysis quantified the morphologic characteristics of the blood vessels in the defect. Variables were measured in relation to the mucosal defect area. Multivariate analysis and a neural network (NNET) were used as prediction models. RESULTS : The CSPEB group vessels had larger maximum diameter (113.07 vs. 69.03; P < 0.001), larger minimum radius (5.09 vs. 3.28; P = 0.002), larger perimeter value (337.82 vs. 193.86; P < 0.001), larger vessel length-of-outline (351.83 vs. 220.68; P = 0.002), and larger fractal dimension (1.11 vs. 1.10; P = 0.005) compared with non-bleeders. Discriminant analysis yielded 86 % sensitivity and 76.7 % specificity and an NNET classifier yielded 100 % sensitivity and 76.9 % specificity for identifying patients at risk. CONCLUSIONS : Blood vessel morphology in the post-EMR defect can be used to predict bleeding following colonic EMR. [ABSTRACT FROM AUTHOR]

After surgical resection for Crohn's disease (CD) endoscopic recurrence is noted within few weeks and almost 80% of patients will have evidence of endoscopic recurrence at the anastomosis after ileocolic resection at 1 year. With time and if left untreated surgical recurrence will be detected at the preanastomotic segment or at the anastomosis in the vast majority of cases. It has become progressively apparent also based on these historical data that anastomotic configuration plays a major role in the subsequent recurrence of CD in surgically induced remission. In this article, we will review the evidence in the literature to support the different anastomotic configurations and we will discuss the principles of surgical prophylaxis of CD recurrence.

Introduction: Mini-invasive surgery in its various modifications is widely used for the surgical treatment of Hirschsprung's disease (HD) in children. The authors from different clinics joined the discussion on mini-invasive techniques with emphasis on the positive and problematic issues of this area of surgical treatment of HD. Aim: to evaluate the positive and problematic technical features of mini-invasive surgery in the treatment of Hirschsprung's disease in children. Material and Methods. Between October 2011 and January 2021, we treated 221 children with HD using a mini-invasive technique. Among them - 156 (70.59%) patients underwent TEPT without laparoscopic assistance and 65 (29.41%) children underwent laparoscopic-assisted TEPT. The results of general clinical and specific research methods were used for diagnosis. Results and Discussion: All children were operated on in one step, without conversion, no intraoperative complications took place. Coloanal anastomosis failure in the early postoperative period was noted in 2 (0.95%) patients. This complication was eliminated conservatively in one patient, and in case of another child this complication was corrected by stepwise open treatment. The postoperative intestinal problems in the remote period occurred in 55 (24.89%) children and were represented by: moderate stenosis of the coloanal anastomosis without delayed fecal discharge - 4 cases (1.81%), constipation - 9 (4.07%), partial fecal incontinence -- 20 cases (9.05%) and enterocolitis - 22 (9.96%). Conclusions: Mini-invasive surgery is a modern effective method of surgical treatment of HD in children of all ages. Mini-invasive methods of surgical treatment of HD in children lead to 0.95% of early and 24.89% of late postoperative complications. The type of complications in the early and remote periods after HD correction depends on a wide range of factors. [ABSTRACT FROM AUTHOR]

Foreign body ingestion is a frequent condition, with the majority of foreign bodies (FBs) tending to spontaneously proceed along the gastrointestinal tract without any major complications. A wide range of procedures are available to remove FBs; however, a real challenge exists in managing sharp, rigid, and long foreign objects, which are related to higher rates of complications. A 34-year-old man who intentionally swallowed a metallic wire of 20 cm length, presented to our ED with abdominal pain 2 weeks after the ingestion. The FB had migrated to the stomach and duodenum. Complications included perforation of the duodenum and ascending colon and a retroperitoneal abscess. FB removal was done via laparotomy, followed by the repair of perforations and damaged tissues. This case highlights the complications of a FB presence in the gastrointestinal tract for 14 days and emphasizes the importance of urgent and appropriate management of such conditions.

Background: Previous studies showed that type 2 short bowel syndrome (SBS) rats were accompanied by severe intestinal bacterial dysbiosis. Limited data are available for intestinal fungal dysbiosis. Moreover, no effective therapeutic drugs are available for these microbiota dysbiosis. The aims of our study were to investigate the therapeutic potential of glucagon-like peptide 2 (GLP-2) for these microbiota dysbiosis in type 2 SBS rats.Methods: 8-week-old male SD rats which underwent 80% small bowel resection, ileocecum resection, partial colon resection and jejunocolostomy, were treated with saline (SBS group, n = 5) or GLP-2 (GLP2.SBS group, n = 5). The Sham group rats which underwent transection and re-anastomosis were given a saline placebo (Sham group, n = 5). 16S rRNA and ITS sequencing were applied to evaluate the colonic bacterial and fungal composition at 22 days after surgery, respectively.Results: The relative abundance of Actinobacteria, Firmicutes and proinflammatory Proteobacteria increased significantly in SBS group rats, while the relative abundance of Bacteroidetes, Verrucomicrobia and Tenericutes decreased remarkably. GLP-2 treatment significantly decreased Proteus and increased Clostridium relative to the saline treated SBS rats. The diversity of intestinal fungi was significantly increased in SBS rats, accompanied with some fungi abnormally increased and some resident fungi (e.g., Penicillium) significantly decreased. GLP-2 treatment significantly decreased Debaryomyces and Meyerozyma, and increased Penicillium. Moreover, GLP-2 partially restored the bacteria-fungi interkingdom interaction network of SBS rats.Conclusion: Our study confirms the bacterial and fungal dysbiosis in type 2 SBS rats, and GLP-2 partially ameliorated these microbiota dysbiosis.

Background: The impact of negative pressure wound therapy (NPWT) as an adjunct to colorectal surgery is largely unknown. The purpose of this study was to determine whether NPWT impacts wound complications during elective open colectomy. Methods: The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) and colectomy targeted procedure databases were queried from 2012-2018 for patients undergoing non-emergent planned open colectomies. Groups were propensity score matched for anastomosis type (ileo-colic, colo-colic, colo-rectal), age, body mass index (BMI), diabetes, smoking, steroid use, wound classification, American Society of Anesthesiologists (ASA) class, operative time, and wound layers closed. Wound complications were defined as superficial surgical site infection (SSI), deep incisional SSI, and dehiscence. Results: A total of 15,770 patients were identified; 92 underwent simultaneous NPWT (0.58%). Non-NPWT patients were matched at a 5:1 ratio, producing 460 comparisons. There was no difference in wound complications (8.26% non-NPWT vs. 6.52% NPWT; p = 0.574). In addition, there were no differences in wound complications when only including patients who had NPWT placed over closed skin (9.11% non-NPWT vs. 7.25% NPWT; p = 0.789). On multivariable analysis, NPWT was not associated with wound complications (odds ratio [OR] 0.79; 95% confidence interval [CI], 0.37-1.69). Conclusions: Negative pressure wound therapy does not reduce wound complications in open elective colectomies. Large randomized studies and more granular data are needed to ascertain if there is any benefit in select patient populations. [ABSTRACT FROM AUTHOR]

Surgical site infection (SSI) is a common preventable iatrogenic infection following surgery with an approximated overall occurrence of 2-4%. Despite numerous studies, controversies still exist regarding the efficacy, safety, and cost effectiveness of strategies to decrease SSI. The World Health Organization issued recommendations for the prevention of SSIs including oxygenation with 80% fraction of inspired oxygen (FiO2). The primary outcome of our systematic review and metaanalysis was the effect of high inspired FiO2 related to SSI in the colorectal surgery population. Secondary outcomes included incidence of anastomotic leaks and length of hospital stay. Eleven trials consisting of 8245 were included in the analysis. We found moderate quality of evidence that 80% FIO2 was not effective in reducing SSI (RR, 0.91; 95% CI, 0.74 to 1.13; P = .41) anastomotic leaks (RR, 0.75; 95% CI, 0.53 to 1.06; P = 0.10). Conversely, we found low quality evidence of no effect on length of stay measured in days (MD, 0.39; 95% CI -0.59 to 1.36; P = 0.44). Although additional studies are required to decrease heterogeneity of the studies, the current review showed high FiO2 does not decrease the incidence of SSI in the colorectal surgery population.

Background: Large prolapse-related lesions (LPRL) of the sigmoid colon have been documented histologically but may not be readily recognized endoscopically.Methods: Colonic lesions referred for endoscopic mucosal resection (EMR) were enrolled prospectively. Endoscopic features were carefully documented prior to resection. Final diagnosis was made based on established histologic criteria, including vascular congestion, hemosiderin deposition, fibromuscular hyperplasia, and crypt distortion.Results: Of 134 large ( ≥ 20 mm) sigmoid lesions, 12 (9.0 %) had histologic features consistent with mucosal prolapse. Distinct endoscopic features were: broad-based morphology; vascular pattern obscured by dusky hyperemia; blurred crypts of varying size and shape; and irregular spacing of sparse crypts. Focal histologic dysplasia was identified in 6 of 12 lesions (50.0 %).Conclusions: LPRL of the sigmoid colon exhibit a distinct endoscopic profile. Although generally non-neoplastic, dysplasia may be present, warranting consideration of EMR. [ABSTRACT FROM AUTHOR]

Background Loop ileostomy construction is a method used to attenuate septic complications. The aims of this study are to examine the epidemiology of loop ileostomy construction and its consequential local and systemic insults in those with left-sided colonic resections. Secondarily, we intend to analyse the difference between early and late ileostomy reversals. We also aim to identify risk factors for acute renal failure (ARF) that may influence a patient's survival and quality of life. Methods A retrospective case-control review was conducted on patients who underwent surgery from 2011 to 2016. The study group included those with a temporary ileostomy formed during a major left-sided colorectal cancer surgery. ARF was defined using the Kidney Disease: Improving Global Outcomes (KDIGO) criteria. Results A total of 467 underwent anterior resection surgery with 200 ileostomies constructed. All patients with ileostomies had enteral continuity restored at a median time of 6 months. Pre-existing renal failure rates was approximately 4.5% in both groups. There were no septic or terminal complications recorded. The risk of developing ARF is 2.6-times that of the control group. Conclusion After major colorectal cancer resection surgery, ileostomy formation carries a 13% risk of developing ARF. Though morbid, the mortality risk with stoma formation is null. In this study, pre-existing diabetes and anti-hypertensives increased the risk of ARF. [ABSTRACT FROM AUTHOR]

Early non compliance to postoperative ERAS pathway has been reported in 20–30% of patients who underwent elective colon surgery. The aim of the present study is to investigate the possible relationship between early non compliance and postoperative complications. We reviewed a prospective database including 1391 consecutively collected patients undergoing elective colon surgery in 22 Italian hospitals between January 2017 and June 2020. Early compliance to ERAS protocol was assessed on postoperative day (POD) 2. Failure of oral feeding, urinary catheter removal, intravenous fluids stop, and adequate mobilization were indicators of non compliance. Postoperative follow-up was carried out for 30 days after hospital discharge. The association among early postoperative ERAS compliance and the occurrence of complications was assessed with uni- and multivariate analysis. A total of 1089 (78.3%) patients had malignancy and minimally invasive surgery was successfully performed in 1174 (84.3%) patients. Postoperative morbidity occurred in 403 (29.0%) patients. At multivariate analysis, male gender, open surgery, and each of the four non compliance indicators on POD 2 were significantly associated to postoperative complications. Morbidity progressively increased from 16.8% in patients with full compliance to ERAS protocol to 47.2% in patients with two non compliance indicators and 69.2% in patients with all four indicators (p < 0.001). Early non compliance to ERAS protocol was significantly associated with postoperative morbidity. [ABSTRACT FROM AUTHOR]

In 2020, the American Association for the Surgery of Trauma (AAST) published a revision of the organ injury scale (OIS) for bowel injuries. The update included for the first time a separate OIS for penetrating colon injuries as well as imaging criteria. To validate the new OIS and its correlation with outcomes, we performed a retrospective review of patients with penetrating colon injuries (AIS<3 in other body regions) between 2016 and 2020 at a single institution. Sixty-six patients met inclusion criteria. Most were young (29 years median) and male (90%). All underwent operative intervention and 23 (34%) had pre-operative imaging. Imaging grade was higher than operative grade in 11 patients (48%). Higher AAST operative grade was associated with a higher likelihood of resection and anastomosis or colostomy, need for damage control laparotomy, and development of intra-abdominal abscess and acute kidney injury. A multicenter study is underway to confirm these findings. [ABSTRACT FROM AUTHOR]

Abstract Background Enhanced recovery after surgery programs (ERAS) using thoracic epidural anesthesia and perioperative patient conditioning with omega-3 fatty acids (n3FA), glucose control (GC) and on-demand fluid therapy, respectively, showed beneficial effects. In the MOFA- study these components were used together in patients undergoing colon or liver surgery. We hypothesized that the use of a perioperative MOFA program improves intestine function represented as time to the first postoperative bowel movement in adult patients compared to standard ERAS. Methods After BfArM and IRB approval 100 patients were enrolled in this prospective randomized controlled trial. All patients received ERAS therapy (control). In addition, the MOFA group received 0.2 g/kg fish oil (Omegaven®), preoperatively, followed by a 48 h continuous infusion of 0.2 g/kg/d n3FA; and GC was kept below

Purpose: Studies on unresectable colorectal cancer liver metastasis(CRLM) rarely analyze the prognosis of the patients from the point of colonic subsites. We aimed to evaluate the effect of primary tumor resection (PTR) and different scope of colectomy on the prognosis of patients with unresectable transverse colon cancer liver metastasis (UTCLM), hepatic flexure cancer liver metastasis (UHFLM), and splenic flexure cancer liver metastasis (USFLM).Patients and Methods: The patients were identified from the Surveillance, Epidemiology, and End Results (SEER) database from 2010 to 2015. Cox proportional hazards regression models were used to identify prognostic factors of overall survival (OS) and cause-specific survival (CSS). Kaplan-Meier analyses and log-rank tests were conducted to assess the effectiveness of PTR on survival.Results: In total, this study included a cohort of 1960 patients: 556 cases of UHFLM, 1008 cases of UTCLM, and 396 cases of USFLM. The median survival time of whole patients was 11.0 months, ranging from 7.0 months for UHFLM patients to 15.0 months for USFLM patients. USFLM patients had the best OS and CSS, followed by UTCLM patients. UHFLM patients had the worst OS and CSS (All P < 0.001). PTR could improve the OS and CSS of UTCLM, UHFLM, and USFLM (All P < 0.001). Subgroups analysis revealed that USFLM patients with tumor size≤5 cm and negative CEA had not demonstrated an improved OS and CSS after PTR. Multivariate analysis showed that PTR and perioperative chemotherapy were common independent prognostic factors for UHFLM, UTCLM, and USFLM patients. There was no difference between segmental colon resection and larger colon resection on CSS of UHFLM, UTCLM, and USFLM patients.Conclusions: We confirmed the different survival of patients with UTCLM, UHFLM, and USFLM, and for the first time, we proved that PTR could provide survival benefits for patients with unresectable CRLM from the perspective of colonic subsites of transverse colon, hepatic flexure, and splenic flexure. Besides, PTR may not improve the prognosis of USFLM patients with CEA- negative or tumor size≤5 cm. For oncologic outcomes, we concluded that segmental colon resection seemed an effective surgical procedure for UTCLM, UHFLM, and USFLM. [ABSTRACT FROM AUTHOR]

Objective: This study was to identify the perioperative related risk factors of postoperative pulmonary complications (PPCs) in elderly patients undergoing elective colorectal surgery, which will provide new insight for better prevention and intervention of PPCs in elderly patients.Methods: A retrospective study involving 445 patients (age ≥65), who registered in Shengjing Hospital affiliated to China Medical University for elective colorectal surgery from October 2014 to March 2017, was conducted. Clinical data, including demographic information, medical history, preoperative examination, and surgery-related factors, were analyzed and compared between the patient group with PPCs and the group without PPCs. t-test or χ2 test was performed for statistical analysis between the 2 groups. Binary logistic regression analysis was further employed to identify the potential independent risk factors of PPCs.Results: Among the 445 patients enrolled in the study, 49 (11%) had PPCs, while 396 (89%) did not. The main risk factors of PPC occurrence in the elderly patients undergoing elective colorectal surgery included older age (age ≥75 years), ASA >II, hypertension, myocardial ischemia, basic pulmonary diseases, laparotomy, blood transfusion, preoperative hemoglobin <100 g/L, and albumin <35 g/L. Laparotomy (compared with laparoscope) and ASA >II were independent risk factors for the increased incidence of PPCs.Conclusion: More attention should be paid to patients with older age and ASA >II in elective colorectal surgery. Choice of laparoscopic operation, proper treatment of hypertension, myocardial ischemia, basic pulmonary diseases, and correction of anemia and nutritional status can effectively reduce the incidence of PPCs. An adequate and comprehensive evaluation of the potential risk factors related to PPCs is required before surgery. [ABSTRACT FROM AUTHOR]
