Background Inguinal lymph node dissection (ILND) is an essential step in both treatment and staging of several malignancies including penile and vulvar cancers. Various open, video endoscopic, and robotic-assisted techniques have been utilized so far. In this review, we aim to describe available minimally invasive surgical approaches for ILND, and review their outcomes and complications. Methods The PubMed, Wiley Online Library, and Science Direct databases were reviewed in February 2020 to find relevant studies published in English within 2000–2020. Findings There are different minimally invasive platforms available to accomplish dissection of inguinal nodes without jeopardizing oncological results while minimizing postoperative complications. Video Endoscopic Inguinal Lymphadenectomy and Robotic Video Endoscopic Inguinal Lymphadenectomy are safe and achieve the same nodal yield, a surrogate metric for oncological adequacy. When compared to open technique, Video Endoscopic Inguinal Lymphadenectomy and Robotic Video Endoscopic Inguinal Lymphadenectomy may offer faster postoperative recovery and fewer postoperative complications including wound dehiscence, necrosis, and infection. The relatively high rate and severity of postoperative complications hinders utilization of recommended ILND for oncologic indications. Minimally invasive approaches, using laparoscopic or robotic-assisted platforms, show some promise in reducing the morbidity of this procedure while achieving adequate short and intermediate term oncological outcomes.

SUMMARY This is a report of one of the many imposters of an irreducible inguinal hernia, a dermoid cyst. It is a rare entity that should be considered in the differential diagnosis of a groin lump when an atypical clinical presentation or groin examination occurs. Complete excision with histological evaluation remains the mainstay of surgical treatment. Keywords: dermoid cyst, inguinal hernia, inguinal canal, incarcerated, hernia surgery

Abdominoscrotal hydrocele (ASH) is a variant of hydrocele that rarely occurs in adults. ASH has two sacs, one in the scrotum and one in the abdomen connected through the inguinal canal. Abdominoscrotal haematocele is a rare complication of ASH. We report a 57-year-old male patient who presented to a tertiary care hospital in Puducherry, India, in 2019 with complaints of swelling in the scrotum for 15 years and abdominal pain for two months. Both the swellings were soft and cross fluctuation was present. Imaging confirmed the diagnosis of ASH. During a diagnostic laparoscopy, the abdominal sac was decompressed and found to have thick brownish fluid suggestive of haematocele. It was demonstrated that both sacs were connected. Due to difficulty in the dissection of the sac, the procedure was converted to an open procedure. Both the sacs were excised and Lytle’s repair was done for the dilated internal ring. The patient recovered and no recurrence of any swelling in the abdomen or scrotum was found at the end of a one-year follow-up.

BACKGROUND The prevalence and incidence of peripheral arterial disease have been increasing in the general population. Although limited data are available on the epidemiology of chronic limb-threatening ischemia, it likely represents

Aims We report the first UK case series of minimally invasive inguinal lymphadenectomy (MILND) for patients with metastatic cutaneous pathology. Methods This is a retrospective, single-centre, single-surgeon cohort study. Twenty one patients who underwent MILND from May 2015 to February 2019 were included. Demographic data, disease burden and surgical quality assurance parameters were analysed. Results Median age was 69 (IQR: 58-76) with 14 females (66%) and 7 males (33%). Eighteen (85%) patients had melanoma with the rest having other skin malignancies. The median number of nodes resected was eight (IQR:6-11) and the median N-ratio was 0.18 [0.05-1.00]. The median surgical time for the procedure was 180 minutes (IQR: 147-225) Seven (33%) patients had complications - three trivial and four (19%) grade IIIB. Only one case (the first) was converted to an open procedure. Conclusions We report the first UK series of MILND in a cutaneous oncology service. Our results show that MILND is a safe technique which can be introduced into a busy NHS practice with a structured training program, with surgical quality assurance outcomes identical to open inguinal lymphadenectomy. Our learning curve was similar to previously published data.

The following article devoted to the case of surgical treatment of giant inguinoscrotal hernia of a patient which signed the informed consent to the processing of personal data with dimensions of hernial sac 400x330x306 mm, size of hernial gates 9x8x7cm, loops of the small intestine, mesentery, a large number of heterogeneous liquid up to 14.7 L were determined in the hernial sac. Left herniotomy was performed. Back wall plastic of the inguinal canal was performed according to Liechtenstein. Mesh implant was used for the plastic.

A newborn male infant was admitted to the neonatal intensive care unit due to suspected sepsis. He was clinically stable with normal electrolyte levels on admission. However, he was noted to have micropenis and bilateral nonpalpable testes. Ultrasound imaging confirmed the presence of both gonads in the inguinal canal, with no Müllerian structures visualized. Laboratory examination revealed an undetectable random plasma cortisol level; subsequent ACTH stimulation testing confirmed adrenal insufficiency. Further testing revealed additional pituitary hormone deficiencies, and the infant was started on multiple hormone replacement therapies. Magnetic resonance imaging identified absent septum pellucidum, pointing of the frontal horns, and optic nerve hypoplasia. A diagnosis of septo-optic dysplasia was made based on this combination of findings. This case highlights the importance of thorough physical examination in newborn infants, which may reveal the only sign of underlying pathology in the absence of other concerning findings.

Transverse testicular ectopia is a rare anomaly characterized by testicular descent into the scrotum through the same inguinal canal. Here, we report the case of a 15-year-old boy diagnosed with transverse testicular ectopia wherein both testes descended through separate inguinal canals. He underwent a diagnostic laparoscopy which helped to identify both spermatic cords entering both inguinal canals separately. During scrotal exploration, both testes were found in the same side. Transseptal orchidopexy was performed. The short-term follow-up is uneventful.

Background: The inguinal hernia is a protrusion of abdominal contents into the inguinal canal through an abdominal wall defect, and the risk of inguinal hernia increases with age. Currently, inguinal hernia repair with a mesh is the mostly common method through surgical procedure. Objective: To compare the outcome of laparoscopic versus open repair for inguinal hernias. Patients and Methods: This prospective comparative study conducted at General Surgery Department, Faculty of Medicine, Zagazig University at the period between January 2021 till July 2021, between open technique (preperitoneal approach, conventional Lichtenstein repair) versus laparoscopic transabdominal preperitoneal (TAPP) and totally extraperitoneal (TEP) mesh repair of inguinal hernia. 24 patients were randomized into 2 groups by the closed envelop method, 12 patients underwent open repair operation and 12 patients underwent laparoscopic repair operation. The clinical diagnosis of inguinal hernia was based on symptoms and signs elicited during clinical assessment. Results: we found that mean duration of operation in laparoscopic group was longer than open group with significant difference, as regard length of hospital stay there was significant differences between two groups. Return to daily activity (Days) was early among laparoscopic inguinal hernia repair group with mean 1.67±0.49 and range from 1 to 2 days versus 4.58±1.5 with range from 3 to 7 days in open repair for inguinal hernia group, the difference was highly statistically significant. Conclusions: Laparoscopic surgical techniques for inguinal hernia repair (TAPP and TEP) can be carried out with a very low rate of predominantly harmless complications and with an acceptable duration of operation.

Purpose of the study. To evaluate morphological changes in the testes in experimental animals after tension-free inguinal hernia repair modeling.Materials and methods. The study included male rabbits, aged 120 days, weighing 3.8 ± 0.9 kg. All rabbits were divided into two groups depending on the type of operation: in the first group (n = 10) of animals, we made a model of tension-free inguinal hernia repair and used a polypropylene mesh; in the second group (n = 10) of animals, we left the structures of the inguinal canal intact. Morphological assessment of spermatogenesis was performed after 40 days. All morphometric measurements were carried out on strictly cross-sections of the convoluted seminal tubules.Results. In rabbits of group 1, the volume of the testicle was significantly three times less than in animals of group 2 (p < 0.05). In the animals of the first group, a significant deterioration in spermatogenesis was observed (p < 0.05). Histological examination of sections of the testes of these animals showed that hypoplasia of the spermatogenic epithelium was present in the convoluted seminal tubules, in 1/8 of the tubules there was subtotal aplasia of the spermatogenic epithelium, Sertoli-Cell-Only Syndrome was detected only in 2 %. Atrophy of the convoluted seminal tubules was not recorded at this period of observation. In the animals of the control group, almost 90 % of cases of spermatogenesis disorders were not detected.Conclusions. This experimental study on rabbits showed that after using a polypropylene mesh for inguinal canal plastic, inhibition of germ cell maturation occurs after 1.5 months. Therefore, in men of reproductive age, it is necessary to use polypropylene mesh implants with caution in terms of performing inguinal hernia repair.

Introduction. Inguinal hernia (IH) — one of the most common childhood diseases that requires surgical treatment. The main indication for surgical treatment of IH is a risk of its strangulation. Among the methods of laparoscopic herniorrhaphy, PIRS (percutaneous internal ring suturing) is especially promising one. Objective of the study — to analyze our own clinical material of surgical treatment for IH in children using PIRS.Materials and methods. The study included 62 children with IH aged 2 months to 7 years, who were operated in 2012–2015 using PIRS method with suturing the internal inguinal ring. Among patients, there were 48 (77.4 %) boys and 14 (22.6 %) girls. Right-sided hernia was diagnosed in 45 (72.6 %) patients, and left-sided one — in 10 (16.1 %). Bilateral IH before surgery was diagnosed in 7 (11.3 %) children. For surgical interventions, we have used straight or 30° 5-mm laparoscope.Results and discussion. Among the advantages of laparoscopic techniques, and particularly PIRS method, there is the ability to detect failure of closure of the processus vaginalis with contralateral side. Thus, in 6 (9.7 %) patients, the expansion of the internal inguinal ring on the opposite side was visualized intraoperatively. Also, the advantage of this method is using a single optical port with the diameter of 3–5 mm and no need for laying on intracorporeal suturing. None of operated patients, when applying thread Ethibond* Excel 2–0, complained about postoperative discomfort in the area of postoperative node, which was placed subcutaneously in the inguinal area. In the study, IH recurrence was detected in 2 (3.2 %) boys. These patients also underwent reintervention using the PIRS technique.Conclusions. PIRS — a simple and efficient minimally invasive method for surgical correction of IH, which has a good cosmetic result. The application of laparoscopic method in the treatment of IH in children allows us to carefully examine the internal inguinal rings and, if necessary, to correct defects on both sides. The use of thread Ethibond* Excel 2–0 for suturing the inner ring of the inguinal canal is effective and provides optimal functional results. The risk of IH recurrence after surgery by PIRS method is a comparative in terms of risk of relapse after classical method surgery.

Background Undescended testis is one of the most common paediatric surgical diagnoses. A lot of research has been done to date, to standardise the surgical management of intra-abdominal and extra-abdominal undescended testis. High inguinal undescended testis is a unique clinical encounter which demands additional surgical measures over conventional orchidopexy for better surgical results. Main body of abstract Open inguinal orchidopexy is a routine and quite straightforward operation for the majority of extra-abdominal undescended testis. However, there are instances in which the testis, even though situated in the inguinal region, poses a challenge for surgeons, to bring it in the scrotum by routine open inguinal orchiopexy. High inguinal testis can be defined as “any intra-canalicular testis present higher up in the inguinal canal and cannot be brought down easily to the scrotum by routine surgery as in standard orchiopexy (open or laparoscopy) and require additional lengthening manoeuvres”. It needs additional surgical lengthening manoeuvres like Prentiss, along with the steps of routine orchiopexy to bring it down in the scrotum. This review article describes the various nomenclatures of undescended testis, appropriate investigations and also various additional surgical measures in the management of difficult high inguinal testis. Conclusion High inguinal undescended testis poses a unique technical challenge even to well-experienced surgeons. It is very important that surgeons dealing with this condition are well aware of the anatomy in this region and also various different manoeuvres described to date to bring the testis down in the scrotum.

Ureteral herniation into the scrotum is rare and often associated with congenital abnormalities or postoperative anatomic changes. A high index of suspicion is needed to avoid intraoperative ureteric injuries. A 50-year-old man with ureteric herniation into an inguinoscrotal hernia reported acute left flank pain and had a history of recurrent urinary tract infections. Contrast-enhanced computed tomographic evaluation revealed a left ureter extending from the pelvis into the scrotum through the inguinal canal. Screening ultrasound of the scrotum revealed the intrascrotal extension of the ureter along with the other hernial contents and diagnosed as a Paraperitoneal inguinal herniation of the ureter. Various cross-sectional imaging modalities, including Ultrasound, provide good anatomic details that can diagnose the presence of a herniated ureter.

AIM: Based on the accumulated clinical material, this study aims to show the possibilities of diagnosing and treating direct inguinal hernias in children. MATERIALS AND METHODS: During the period from 2000 to 2020, 3221 children with inguinal hernias were treated in the surgical department of the Republican Childrens Clinical Hospital in Syktyvkar. Of the above group of children with inguinal hernias, seven patients (0.22%) had direct inguinal hernias. The above was confirmed by ultrasound examination. In laparoscopic imaging, a rectal hernia was defined as a recess of the peritoneum of a stellate or rounded shape in the projection of the medial umbilical fossa. Two patients underwent the Bassini herniation procedure. Two children underwent laparoscopic hernia repair with intracorporeal suture insertion. In three patients, hernia repair was performed using the PRMS method. RESULTS: Long-term results were followed up from six months to 15 years. Immediate and postoperative complications were noted. No recurrence of hernia was reported. CONCLUSIONS: When establishing direct inguinal hernia diagnosis in children is clinically determined in the form of a rounded, soft-elastic formation localized medially and above the Pupart ligament next to the projection of the external (superficial) inguinal ring of the inguinal canal. It is easily set into the abdominal cavity with rumbling and confirmed by ultrasound examination results. The most preferred treatment method for direct inguinal hernia in children, in our opinion, is hernia repair using the percutaneous internal ring suturing (PIRS) method.

To (1) examine the contemporary incidence of occult inguinal LN metastases and (2) identify predictors of occult inguinal LN metastases to improve selection of cN0 patients for inguinal lymphadenectomy (ILND).We identified 590 men with cTany cN0 cM0 penile cancer who underwent partial/radical penectomy and ILND from 2006-2016 in the NCDB. Rates of pN+ disease were examined, and a multivariable regression model was constructed to identify features associated with pN+ disease.Tumors were ≤pT1 in 21%, pT2 in 43%, and pT3/pT4 in 24% of patients. A median of 15 (IQR 8-22) LNs were removed at ILND. The overall pN+ rate was 24% and did not vary over the study period. The pN+ rate, stratified by pT stage, varied from 18-33%. On multivariable analysis, only higher tumor grade (OR 2.16; P = 0.02 for grade 2; OR 2.81; P = 0.005 for grade 3-4, versus grade 1) and lymphovascular invasion (OR 3.12; P0.001) were independently associated with pN+ disease, whereas pT stage was not.The contemporary rate of occult LN metastases in men with cN0 penile cancer remains high at approximately 24%. Our results suggest that high tumor grade and/or lymphovascular invasion are better determinants of lymph node involvement than primary tumor stage.

Objective:to evaluate the existing approaches to the treatment of inguinal hernias in the elderly and to propose a strategy for choosing the method of surgical treatment taking into account the metric assessment of the state of the topographical and anatomical parameters of the inguinal canal.Materials and methods.The analysis of surgical interventions for inguinal hernias in elderly patients in surgical in-patient clinics of the Grodno region over 2018–2019 was carried out. The morphometric parameters of the inguinal canal being determinants for choosing the method of hernioplasty were studied in 39 elderly patients.Results.The coefficient for choosing the method of inguinal herniation (K) has been proposed. It is calculated by the formula: К = h : m, where h is the height of the inguinal space (mm), m is the total thickness of the upper wall of the inguinal canal (mm). At K>4.83 they choose atension methods of hernioplasty.Conclusion.The use of the coefficient for choosing the method of inguinal hernioplasty has made it possible to reduce the number of recurrent hernias in the long-term postoperative period from 5.7 % to 2.0 % of cases.

Purpose. To give a comparative description of the topographic and anatomical parameters of the inguinal canal in hernias and to evaluate its importance in choosing a method of hernioplasty. Material and methods. In 120 patients with types II, IIIa, IIIb inguinal hernias, the height of the inguinal space (h-IS), the total thickness of the internal oblique and transverse abdominal muscles forming the upper wall of the inguinal canal (TMT) and the diameter of the deep inguinal ring (DDIR) were measured intraoperatively. Results. Pairwise comparisons of the IS height revealed statistically significant differences in this parameter between hernias types II and IIIa, as well as between types II and IIIb (p = 0.0432) in all age groups. In the studied age groups, there were statistically significant differences in the diameter of the deep inguinal ring between patients with hernias types II and IIIa, as well as types II and IIIb (p

The Canal of Nuck (CN) is an anatomical structure which is often forgotten. It is the female equivalent of the male processus vaginalis and corresponds to a protrusion of parietal peritoneum that extends from the inguinal canal to labia majora. Radiologists rarely encounter patients with pathology of CN, especially in adult population. It is well known that CN diseases can occur in paediatric patient (especially younger than 5 years of age) and they are associated to high morbidity (for example ovarian hernia with high risk of incarceration and torsion). The aim of our work is to review embryology, anatomy and pathologies of the CN thanks to a multi modal approach-ultrasound (US), Computed Tomography (CT) and Magnetic Resonance imaging (MRI)-to make radiologists more aware of such conditions and guarantee a prompt and correct diagnosis not only in paediatric patients but also in the adult population.

The purpose of this study was to assess the psychometric properties of the Simplified Inguinal Pain Questionnaire (sIPQ) and compare it to the regular Inguinal Pain Questionnaire (IPQ) for external validation. To do so, the IPQ and sIPQ were telephonically administered at 7 and 28 days postoperatively for a cohort of 25 patients who underwent Lichtenstein hernioplasty. A psychometric analysis of the scores was done using Cronbach’s alpha and test–retest assessments. The agreement rate of the mean-standardized values between scores was afterwards calculated. We found closely similar psychometric values for the IPQ and sIPQ. The agreement rate between scores was 97% (p

Inguinal hernia repair involves a variety of approaches. Among the multitude of procedures available, the Gold Standard Procedure of Inguinal Hernia repair in recent times is the Lichtenstein’s Tension free mesh hernia repair. When placed intra-operatively, the direct contact of the mesh and associated peri-mesh fibrosis to the vessels in the inguinal canal, there exists a possibility of impaired testicular blood flow and subsequent postoperative morbidity of testicular atrophy. Testicular perfusion, its relation to testicular atrophy is well documented.

Objective To evaluate predictors of failure of microsurgical spermatic cord denervation (MSCD) for men with chronic orchialgia. Methods Retrospective chart review of men who underwent MSCD. Outcomes were recorded with potential preoperative predictors of failure. Results One hundred and five men underwent MSCD, and of those, 38 were bilateral for a total of 143 testicular units. Overall, 97 of 143 (67.8%) had complete resolution of pain, 27 of 143 (18.9%) had improvement of pain, and 19 of 143 (13.3%) were considered failures with either no improvement or less than 50% improvement in pain after MSCD with a 1-year follow-up period. Overall, 59 of 143 (41%) presented with intermittent orchialgia while 84 of 143 (59%) presented with constant pain. The mean preoperative visual analog scale was 6.8 ± 2 and the mean duration of pain prior to MSCD was 62.5 ± 100 months. Potential etiologies of pain per testicular unit included previous scrotal/inguinal surgery 17 of 143 (11.9%), postvasectomy pain syndrome (PVPS) 30 of 143 (21%), infectious epididymitis 9 of 143 (6.3%), trauma 15/143 (10.5%), and idiopathic 72/143 (50.3%). The only pre-operative predictor having an association with predicting failure was the etiology of orchialgia. Relative to men who had idiopathic orchialgia or prior scrotal/inguinal surgery inciting orchialgia, men with PVPS had increased odds of failure with MSCD. Conclusion PVPS is an etiology associated with a higher risk of failure to respond to MSCD than idiopathic chronic orchialgia or chronic orchialgia subsequent to scrotal/inguinal surgery.

The present communication relates to inguinal hernia repair, and more particularly to a preshaped inguinal hernia prosthetic material, polypropylene, 6×2.5 centimeters in size, (Figure 1) that has a lateral semicircular non-encircling cord locating structure in order to protect the spermatic cord and that it is interposed between the conjoined tendon and the inguinal ligament in such a way as to repair the hernia and at the same time to reconstitute the physiology of the inguinal canal.

The aim of our study was to recommend a novel method for measuring the distance from the umbilicus to intra-abdominal organs, as well as recommend an instrument length that would accommodate transumbilical laparoendoscopic single-site (U-LESS) surgeries to these areas. From CT scans of 50 men and 50 women, we calculated the distance from the umbilicus to 11 intra-abdominal points of interest using two triangles oriented perpendicular to each other. Using known lengths of the triangles, we used the Pythagorean theorem to calculate distances with and without insufflation. Distances were measured from the umbilicus to the xyphoid process, superior most aspect of the spleen, neck of the gallbladder, bifurcation of the descending aorta, adrenal glands, superior pole(s) of the kidneys, inferior most aspect of the inguinal canal, suprapubic margin, and the apex of the prostate (or female bladder neck). We found that an instrument working length of 43 cm would be sufficient to facilitate U-LESS surgery for all of our patients to each of the measured points of interest. The technique described in this paper serves as a useful method by which to measure the distance from the umbilicus to any intra-abdominal point of interest. These measurements would allow surgeons to correctly select instruments with adequate length when planning to perform U-LESS surgery.

Aim While the scientific evidence in favour of negative pressure wound therapy (NPWT) dressings on sutured incisions in the prevention of surgical site infections (SSIs) has increased, the cost-effectiveness after vascular surgery has not been evaluated. The aim of this study was to evaluate the cost-effectiveness of NPWT compared to standard dressings for the prevention of SSIs after open inguinal vascular surgery. Materials and methods Patient data were retrieved from the randomised INVIPS-trial's open arm, which included patients randomised to either NPWT or standard dressings. The patients were surveyed for SSIs for 90 days postoperatively. The patients' individual cost data were included and analysed from a healthcare perspective. The patients' quality of life was measured using the Vascuqol-6 questionnaire pre- and 30 days postoperatively. Cost-effectiveness of NPWT was determined by decreased or equal total costs and a significant reduction in SSI incidence. Results : The mean vascular procedure-related costs at 90 days were €16,621 for patients treated with NPWT (n = 59) and €16,285 for patients treated with standard dressings (n = 60), p = 0.85. The SSI incidence in patients treated with NPWT was 11.9% (n = 7/59) compared to 30.0% (n = 18/60) with standard dressings, p = 0.015. This corresponds to an increased mean cost of €1,853 per SSI avoided. The cost-effectiveness plane of incremental vascular procedure-related costs and difference in Vascuqol-6 score showed that 42% of estimates were in the quadrant where NPWT was dominant. Conclusion: NPWT is considered cost-effective over standard dressings in patients undergoing open inguinal vascular surgery due to reduced SSI incidence at no higher costs.

This article deals with the rare clinical observation of the patient with recurrent desmoid-type fibromatosis, who have achieved long-term stability after surgical treatment. A 24-year-old patient was diagnosed with retroperitoneal tumor which size was 8.85.613 cm in 2013, infiltrating the left psoas muscle, left kidney, left common and left external iliac arteries, descending colon and sigmoid colon. The patient underwent surgery in the volume of the tumor removal, resection of the left common iliac artery and prosthetics using GORE-TEX prosthesis, left hemicolectomy, left nephrectomy at Blokhin National Medical Research Center of Oncology. The first recurrence of the tumor was detected nine months after the surgery. Due to the subsequent growth of tumor mass, located along the left external iliac artery and in the inguinal canal, the repeated surgery was performed. Then the patient had a second relapse, and underwent surgery again. The third recurrence was detected seven months after the last surgery. During the multidisciplinary discussion, according to the absence of complaints and the small size of the recurrent tumor, as well as the absence of the risk of life-threatening complications, it was decided to stop on the observation. The patient was examined once every six months there were no data concerning recurrent tumor growth. Today, the patient is alive, does not have any complaints and is able-bodied. Our clinical observation demonstrates that active surgical tactics in case of the retroperitoneal fibromatosis recurrence not always can lead to long-term progression-free survival time and several patients can stay under the observation, using Look and Stay tactic.

The aim of this study is to present our treatment protocol for impalpable testis.In a retrospective study we analyzed clinical data including diagnostic procedures, intraoperative findings, final diagnosis, treatment modality, and outcome of patients with impalpable testis who underwent surgery from January 2010 until December 2015.Ninety-one patients were admitted under the diagnosis of impalpable testis. In 39 patients ultrasound detected testis in the inguinal canal and orchidopexy was done. In 25 patients (48.08%) laparoscopy showed the entrance of the spermatic cord into the inguinal canal. Open exploration of the inguinal canal was done, testicular remnant removed, and appropriate testicular prosthesis implanted. Twenty patients (20/52) underwent orchidopexy of the abdominal testis (46.51%), 4 of which underwent Fowler-Stevens procedure in two stages, and in 16 patients deliberation of the testis and spermatic cord was sufficient to place the testis into the scrotum.Excision of the testicular nubbin is highly recommendable, as well as implantation of the testicular prosthesis at the time of orchiectomy.

Liposarcoma of the spermatic cord is a malignant tumor so rare that there are less than 200 cases reported in the literature worldwide. Liposarcoma is a malignancy which originates from fat tissue. Although only 3%-7% of all paratesticular sarcomas primarily arise from structures of the spermatic cord, clinical significance of these tumors must not be neglected because they are often preoperatively misdiagnosed. A 66-year-old male presented with a painless swelling on the left side of the scrotum. Local examination revealed a solid, smooth, limited mass of approximately 4x3 cm in the left side of the scrotum. Tumor markers were within the reference range. Ultrasound examination showed a solid, clearly limited non-homogeneous mass of 40x20 mm localized in the left spermatic cord. Magnetic resonance imaging showed an expansive mass measuring 60x85x60 mm in the left inguinoscrotal region without propagation into the abdominal cavity. Both testicles and epididymides appeared normal on magnetic resonance examination and no locoregional enlarged lymph nodes were seen. The patient was treated operatively with radical inguinal orchiectomy. In conclusion, liposarcomas of the spermatic cord are extremely rare neoplasms that clinically present as slow-growing, painless, palpable inguinal or scrotal masses. Radical orchiectomy with high ligation of the spermatic cord and wide excision of the surrounding soft tissues within the inguinal canal remains the gold standard treatment option. Recurrence of the disease is frequent even several years after primary therapy, therefore long-term follow-up is mandatory., Liposarkom sjemenske vrpce je toliko rijedak maligni tumor da je do sada opisano manje od 200 slučajeva u literaturi. Liposarkom je malignitet koji vodi podrijetlo od masnog tkiva. Iako samo 3%-7% svih paratestikularnih sarkoma primarno potječe od struktura sjemene vrpce, kliničko značenje ovih tumora ne smije se zanemariti, jer ih se često prijeoperacijski pogrešno dijagnosticira. U radu je prikazan bolesnik u dobi od 66 godina s kliničkom slikom bezbolne tumefakcije hemiskrotuma s lijeve strane. Lokalni nalaz je ukazivao na solidnu, glatku, jasno ograničenu masu veličine oko 4x3 cm u lijevom hemiskrotumu. Vrijednosti tumorskih biljega bile su unutar referentnih vrijednosti. Na ultrazvučnom pregledu opisana je solidna, jasno ograničena nehomogena masa dimenzija 40x20 mm u lijevoj sjemenoj vrpci. Magnetska rezononacija abdomena i zdjelice pokazala je ekspanzivnu masu u lijevoj ingvinoskrotalnoj regiji veličine oko 60x85x60 mm bez znakova propagacije u abdominalnu šupljinu. Na magnetskoj rezonanciji testisi i epididimisi su imali normalan izgled i nisu uočeni uvećani lokoregionalni limfni čvorovi. Bolesnik je tretiran operativno, napravljena je radikalna orhiektomija ingvinalnim pristupom. U zaključku, liposarkomi sjemene vrpce su ekstremno rijetke neoplazme koje se klinički manifestiraju kao sporo rastuće, bezbolne, palpabilne ingvinalne ili skrotalne mase. Radikalna orhiektomija s visokim podvezivanjem sjemene vrpce i širokom ekscizijom okolnih mekih tkiva unutar ingvinalnog kanala predstavlja zlatni standard liječenja. Recidiv bolesti je čest, čak i nekoliko godina nakon primarnog liječenja te je dugačko razdoblje praćenja obvezatno.

Background Inguinal hernia repair is one of the most common general surgical operations worldwide. We present a case of indirect inguinal hernia containing an expanded portosystemic shunt vessel. Case summary We report a 72-year-old man who had a 4 cm × 4 cm swelling in the right inguinal region, which disappeared with light manual pressure. Abdominal-pelvic computed tomography (CT) revealed a right inguinal hernia containing an expanded portosystemic shunt vessel, which had been noted for 7 years due to liver cirrhosis. We performed Lichtenstein's herniorrhaphy and identified the hernia sac as being indirect and the shunt vessel existing in the extraperitoneal cavity through the internal inguinal ring. Then, we found two short branches between the expanded shunt vessel and testicular vein in the middle part of the inguinal canal and cut these branches to allow the shunt vessel to return to the extraperitoneal cavity of the abdomen. The hernia sac was returned as well. We encountered no intraoperative complications. After discharge, groin seroma requiring puncture at the outpatient clinic was observed. Conclusion If an inguinal hernia patient has portal hypertension, ultrasound should be used to determine the contents of the hernia. When atypical vessels are visualized, they may be shunt vessels and additional CT is recommended to ensure the selection of an adequate approach for safe hernia repair.

Background Transverse testicular ectopia (TTE) is a rare anomaly in which both testes descend through a single inguinal canal into the same hemiscrotum. Although almost 20–50% of patients with TTE exhibit persistent Müllerian duct syndrome (PMDS) and many genetic analyses have been performed, no reports have described the genes contributing to TTE without PMDS. Here, we report two cases of TTE without PMDS using immunohistochemical staining and genetic analysis. Case presentation Two Asian patients with TTE without PMDS were subjected to orchiopexy. We performed testicular biopsies during operation and obtained blood samples before the operation. Testicular tissues were stained for c-kit, placental alkaline phosphatase (PLAP), and undifferentiated embryonic cell transcription factor 1 (UTF1) to evaluate the presence of intratubular malignant germ cells. Additionally, we performed polymerase chain reaction-based direct sequencing to identify single nucleotide polymorphisms in genes associated with regression of the Müllerian duct and testicular descent (that is, anti-Müllerian hormone [AMH], AMH receptor 2 [AMHR2], insulin-like 3 [INSL3], and relaxin family peptide receptor 2 [RXFP2]). The three-dimensional structures of proteins were predicted using SWISS-MODEL. In immunohistochemical analysis, c-kit and UTF1 were positive, whereas PLAP was negative in three testicular tissue samples from the two patients. These features were also detected on the unaffected side. In variant analysis, common missense variants in the AMH gene (g.365G>T; c.165G>T; p.Ser49Ile [rs10407022]) were observed. All variants in INSL3 and RXFP2 genes were intronic or silent. Conclusions Because UTF1, a specific marker of spermatogonial stem cell activity, was expressed in both the affected and unaffected sides in the testicular tissues of two patients, the risk of malignancy may be high in these patients. Although the etiology of TTE without PMDS remains unclear, our variant analysis results were consistent with previous reports, and variants in the AMH gene (rs10407022) may contribute to the specific phenotype of TTE without PMDS.

Background The hernia is defined as the protrusion of any organ or a part of it through the wall or fascia or any connective tissue which normally encloses that organ. Among the hernias, an inguinal hernia is the most common type. In the inguinal hernia, Amyand hernia is one of the rare types, in which the appendix will herniate through the inguinal canal. The incidence of Amyand hernia is less than 1% (Namdev et al., Int Surg J 7:2072, 2020). Case presentation We are reporting a case of Amyand hernia, which was diagnosed incidentally in the patient who had been referred to computerized tomography (CT) for a malignant melanoma metastasis screening. Our case is unique in that pre-operative diagnosis of the Amyand hernia is rarely reported in the literature. We can diagnose the type 1 Amyand hernia with utmost confidence. Conclusion Pre-operative diagnosis of type 1 Amyand hernia can be made with utmost certainty by CT.

Background Anal SCC is a rare disease mainly treated with chemoradiation. Abdominoperineal resection (APR), once the mainstay of treatment for anal cancer, now serves a role as salvage therapy for persistent or recurrent disease after chemoradiation. In addition, clinically positive nodes are currently treated by extending the radiation field to the groin. The role of inguinal lymph node dissection in recurrent or persistent anal SCC is unclear. The aim of the study is to determine the role of inguinal lymph node dissection in the management of inguinal lymph node metastasis for anal squamous cell carcinoma (SCC). Methods Retrospective analysis of patients with anal SCC in the National Cancer Database with positive inguinal nodes undergoing salvage APR between 2004 and 2014 was performed. A comparison of overall survival between patients who underwent APR with lymph node dissection versus APR only was analyzed using Kaplan-Meier plot. Results A total of 3424 patients underwent salvage APR, with 274 (8%) having clinically positive nodes. Within the subgroup that had clinically positive nodes, 195 (71%) underwent APR, whereas 79 (29%) underwent both APR and node dissection. Kaplan-Meier analysis demonstrates no difference in overall survival in the two groups (P = 0.99). Five-year survival for both groups was similar (36% versus 42%; P = 0.987). No significant difference was found when adjusted for age, gender, and Tumor Node Metastasis staging. Conclusions Inguinal lymph node dissection does not appear to improve overall survival in patients with advanced-stage anal cancer requiring salvage APR. Proper patient selection for node dissection is essential to spare patients from additional morbid procedures.

Objectives: This review aims to study the role of the abdominal wall in testicular migration process during the human fetal period. Materials and Methods: We performed a descriptive review of the literature about the role of the abdominal wall in testicular migration during the human fetal period. Results: The rise in intra-abdominal pressure is a supporting factor for testicular migration. This process has two phases: the abdominal and the inguinal-scrotal stages. The passage of the testis through the inguinal canal occurs very quickly between 21 and 25 WPC. Bilateral cryptorchidism in Prune Belly syndrome is explained by the impaired contraction of the muscles of the abdominal wall; mechanical obstruction due to bladder distention and structural alteration of the inguinal canal, which hampers the passage of the testis during the inguinoscrotal stage of testicular migration. Abdominal wall defects as gastroschisis and omphaloceles are associated with undescended testes in around 30 to 40% of the cases. Conclusions: Abdominal pressure wound is an auxiliary force in testicular migration. Patients with abdominal wall defects are associated with undescendend testis in more than 30% of the cases probably due to mechanical factors; the Prune Belly Syndrome has anatomical changes in the anterior abdominal wall that hinder the increase of intra-abdominal pressure which could be the cause of cryptorchidism in this syndrome.

Highlights • Herniation of the ureter into the inguinal canal is a rare occurrence. • There have been reports of inadvertent injury to the ureter during routine inguinal hernia repair. • After an extensive search of the literature, we believe this is the 1stcase to be managed by Laparoscopic TAPP Repair. • Presence of ureter buried in a large amount of fat can be mistaken for lipoma of the cord and injured with blind clamping. • Presence of unilateral hydroureteronephrosis in a patient with inguinal hernia should prompt a surgeon to proceed with CT., Introduction Herniation of the ureter into the inguinal canal is a rare occurrence. There have been reports of inadvertent injury to the ureter during routine inguinal hernia repair. After an extensive search of the literature, we believe that this is the first case to be managed via laparoscopic Trans Abdominal Pre-Peritoneal Repair and would like to highlight the technical details of the laparoscopic procedure and is presented in line with SCARE 2018 Guidelines [1]. Presentation of case A 60-year-old male presented with left inguinal hernia. He also complained of an increase in frequency of micturition, with an occasional radiating pain from loin to the groin. Imaging revealed the left ureter coursing into the left inguinal canal, descending into the scrotum, and looping back to enter the bladder with mild hydroureteronephrosis. Patient underwent a laparoscopic repair of the inguinal hernia with reduction of ureter under ureteroscope guidance and stent placement. Discussion The presence of ureter buried in a large amount of fat can be mistaken for a lipoma of the cord or extraperitoneal fat and injured with blind clamping and division. Presence of fat without an obvious sac should alert the surgeon to the possibility of ureter being a content. Conclusion Laparoscopy is safe, technically feasible, offers good visualization of all hernial orifices, demonstrates complete reduction of ureter from inguinal canal under vision, allows manipulation of ureter under the vision for ureteroscopy and stenting, making sure there are no loops or kinking and allows placement of mesh in the preperitoneal space.

Background and objectives The aim of our study was to analyze the results of selective inguinal node irradiation in patients with anal cancer, based on the biopsy of the inguinal sentinel lymph node (SLN), in terms of local control and prognosis. Methods Records of patients with anal squamous cell carcinoma from January 2001 to December 2016 were retrospectively reviewed. Tc99 lymphoscintigraphy was performed in all the clinically inguinal negative patients, followed by radio-guided surgical removal of the inguinal SLN. All patients were treated with combined radiochemotherapy. In patients with negative sentinel nodes, the inguinal area was excluded in the radiotherapy field. Results A total of 123 patients, 76 females (61.8%), mean age 60.1 ± 12.19 years old, underwent intraoperative lymph node retrieval. The histological analysis showed metastasis in the SLN in 28 patients (22.8%). The mean follow-up was 43.44 ± 31.86 months. No inguinal recurrence was observed in patients with negative inguinal sentinel node(s). A statistically significant difference was observed for overall and disease-free survivals in a patient with positive and negative inguinal sentinel nodes. Conclusions In patients with anal canal cancer, the exclusion of the inguinal regions from the radiotherapy field, in patients with negative SLN, does not compromise locoregional control nor prognosis.

A 7-year-old girl was referred to our hospital with a suspected right-sided indirect inguinal hernia. An egg-sized elastic, non-painful mass was palpated in the right inguinal region. Preoperative CT demonstrated a 30-mm simple cystic mass in the right internal inguinal canal, which we diagnosed as an abdominal cyst of the canal of Nuck. Laparoscopy revealed that the abdominal cystic component was ruptured, so we performed Pott's procedure. However, the patient's right groin swelled on postoperative day 3, necessitating re-operation. The patient's symptoms recurred again after 3 months, despite having had two surgical repairs. In the third operation, a right-sided femoral hernia was confirmed and repaired via external and laparoscopic approaches. To the best of our knowledge, there have been no reports on the combination of femoral hernia and cyst of the canal of Nuck in children. A laparoscopic approach was useful for obtaining a definitive diagnosis and conducting a safe and secure surgical repair.

The inguinal canal anatomy is of paramount clinical significance due to the common occurrence of direct and indirect inguinal hernias. However, the inguinal canal is often an area of great difficulty for medical students to understand. The aim of this study was to evaluate the use of a low-cost, low-fidelity inguinal canal model as a teaching and learning aid. A low-fidelity inguinal canal model was introduced as a learning aid in an anatomy tutorial on the inguinal region. Students were randomised into intervention (n = 66) and control (n = 40) groups. Following the tutorial, all students completed a multiple-choice question quiz on the inguinal canal. The intervention group also completed a questionnaire evaluating the positive and negative aspects of the model. Students taught with the inguinal canal model achieved higher scores (mean: 88.31% vs 81.7%, p = 0.087). Positive aspects of the model as described by the students included its simplicity and ability to improve their three-dimensional understanding of the inguinal canal. Students requested more hands-on time with the model during the tutorial. The present study supports current literature in that low-fidelity anatomy models are a useful adjunct to aid students’ learning of complex anatomical concepts. Students may benefit from creating their own inguinal canal model to retain as a personal study tool.

Purpose Lymphatic complications occur frequently after radical inguinal lymph node dissection (RILND). The incidence of lymphatic leakage varies considerably among different studies due to the lack of a consistent definition. The aim of the present study is to propose a standardized definition and grading of different types of lymphatic leakage after groin dissection. Methods A bicentric retrospective analysis of 82 patients who had undergone RILND was conducted. A classification of postoperative lymphatic leakage was developed on the basis of the daily drainage output, any necessary postoperative interventions and reoperations, and any delay in adjuvant treatment. Results In the majority of cases, RILND was performed in patients with inguinal metastases of malignant melanoma (n = 71). Reinterventions were necessary in 15% of the patients and reoperations in 32%. A new classification of postoperative lymphatic leakage was developed. According to this definition, grade A lymphatic leakage (continued secretion of lymphatic fluid from the surgical drains without further complications) occurred in 13% of the patients, grade B lymphatic leakage (persistent drainage for more than 10 postoperative days or the occurrence of a seroma after the initial removal of the drain that requires an intervention) in 28%, and grade C lymphatic leakage (causing a reoperation or a subsequent conflict with medical measures) in 33%. The drainage volume on the second postoperative day was a suitable predictor for a complicated lymphatic leakage (grades B and C) with a cutoff of 110 ml. Conclusion The proposed definition is clinically relevant, is easy to employ, and may serve as the definition of a standardized endpoint for the assessment of lymphatic morbidity after RILND in future studies.

Objective Congenital Mullerian duct malformations are a challenging group of conditions for surgeons and need surgical experience and skill. Accordingly, the aim of this study is to present the diagnosis, surgical management, and clinical implications of congenital uterovaginal abnormalities. Methods Between 1980 and 2015, 8 patients with congenital uterovaginal abnormalities were diagnosed. In one patient a unique case of an unusual horseshoe shaped double uterus communicating via a transverse canal along with agenesis of the cervix and vagina was noted, and utero-vaginal agenesis was diagnosed in 6 patients. Complete androgen insensitivity syndrome with its female phenotype associated with bilateral testicular tissue in the inguinal canal with an accompanying absence of the ovaries, uterus, uterine tubes, vagina, and an imperforate hymen, was diagnosed in one patient. Clinical examination of all the patients revealed well-developed secondary sexual characteristics. A modified McIndoe vaginoplasty procedure was the surgical treatment common to all patients to treat vaginal agenesis. The surgery was performed by a consultant (Dr. K.G. Paul) using the standardized surgical technique. Results An unusual Mullerian duct anomaly, uterus bicornisacollis, was successfully corrected by uteroplasty and a new cervix was constructed. Complete vaginal agenesis was corrected by a modified McIndoe vaginoplasty technique. None of the patients had any significant post-operative complications. Conclusion Knowledge of congenital uterovaginal abnormalities diagnosed in this study is essential for surgeons, clinical anatomists, radiologists, and morphologists who may increase the success of their diagnostic evaluations and surgical approaches to the region.

One of the most intriguing eras in the evolution of hernia surgery is the second half of the 18th century, when surgeons interested, also, in anatomy, started to publish studies on the abdominal wall and the inguinal canal. Petrus Camper (1722–1789), a well-known “praelector anatomiae” of the Amsterdam Guild of Surgeons and Professor of Anatomy and Surgery at the Universities of Franeker, Amsterdam, and Groningen, performed dissections on corpses of children and adults to study the anatomy and aetiology of inguinal hernias. He rejected the prevailing concept of that time that a hernia was caused by “a rupture of the peritoneum” and provided a clear description of the aetiology of hernias in both children and adults. His geometrical measurement of the pelvis and his acquired craftsmanship provided the basis for the development of an effective and reliable truss to treat inguinal hernia conservatively. His artistic and drawing talent rendered him great facility in presenting his anatomical observations of the inguinal canal in a marvelous way. Campers “Icones herniarum” include exceptional anatomical illustrations of inguinal hernias. His anatomic studies allowed the development of hernia surgery based on anatomy rather than barbaric castration by ancient “herniotomists”. Petrus Camper should be considered as a pioneer in anatomy and aetiology of inguinal hernias.

Introduction: The miniinvasive approach is a trend in pediatric surgery nowadays. The new surgical technique called percutaneous internal ring suturing (PIRS) is a promising method bringing all the benefits of miniinvasive surgery. Methods: Prospective study of patients operated on using the PIRS technique from 01 January 2018 to 01 January 2020 at the Department of Pediatric Surgery, 2nd Faculty of Medicine, Charles University, University Hospital Motol. Results: 73 patients (25 boys and 48 girls) were operated on using PIRS. The median age was 68 months. 90 % of operations were performed by the same team of surgeons. During the procedure there were found 53 right-sided and 38 left-sided inguinal hernias. In 18 cases the hernia was bilateral, but only in 13 cases was this diagnosis made before the operation. A non-absorbable stitch was used in 57 cases to close the internal ring of the inguinal canal, and a non-absorbable monofilament in 16. The median operating time was 34 minutes. There were 3 recurrences (3.3 %) in our study. Conclusion: In our initial study, the PIRS technique proved to be a safe alternative method to the open inguinal hernia surgery. This method provides the benefit of allowing to revise the contralateral inguinal canal as a prevention of a metachronous inguinal hernia. The cosmetic results were excellent.

Altered composition of collagen and elastin in abdominal fascia has been linked with the pathogenesis of hernias. This has not been studied amongst Africans who have hernia presentations which vary significantly from Caucasian cohorts. The aim of this study was to determine, and compare, the collagen and elastin contents of the transversalis fascia and rectus sheath of inguinal hernia patients with non-hernia controls. Twenty-five patients with solitary, primary, uncomplicated inguinal hernia and twenty-five non-hernia controls were evaluated. Biopsies of the transversalis fascia and anterior rectus sheath were stained with Masson Trichrome and Verhoeff van-Gieson to isolate collagen and elastin respectively, which were quantified using the ImageJ/Fiji® image analysis software. Inguinal hernia patients were aged 19–85 years with a mean age of 45.2 years, mean body mass index (BMI) of 23.3 kg/m2 and mean duration of hernia of 42.5 months. Lateral hernias with no hernia defect or posterior wall defect [PL0] were the predominant clinical type. There were significantly lower collagen and higher elastin content in the transversalis fascia and rectus sheath of inguinal hernia patients [P

Highlights • We present a rare case of retroperitoneal liposarcoma with an inguinal swelling, which was diagnosed after laparoscopic surgery for inguinal hernia. • It is necessary to consider a possibility of enlargement of retroperitoneal liposarcoma and perform CT or MRI of the abdomen and pelvis in cases of irreducible inguinal swelling of retroperitoneal fatty tissue., Introduction Liposarcomas comprise around 10%–16% of soft tissue sarcomas. The two major sites of liposarcoma are the extremities and retroperitoneum. However, retroperitoneal liposarcomas mimicking inguinal hernia are rare. We present a case of retroperitoneal liposarcoma mimicking inguinal hernia, which was diagnosed after laparoscopic surgery and underwent curative resection. Presentation of case A 46-year-old man was admitted to our hospital with a right inguinal pain and swelling that had been recognized for 3 years. We diagnosed the inguinal swelling as a right inguinal hernia and planned laparoscopic surgery for inguinal hernia repair. A hernia sac, however, was not found and swollen retroperitoneal fatty tissue near the right internal inguinal ring was observed by laparoscopy. We aborted the surgical procedure and performed computed tomography and magnetic resonance imaging, which revealed an extraperitoneal and lipomatous tumor extending through the inguinal canal to the scrotum. Wide local excision of the tumor, along with right orchidectomy, was performed under laparotomy. Histopathological diagnosis showed well-differentiated liposarcoma of the retroperitoneum and confirmed tumor-free margins. No evidence of recurrence or metastasis was seen in the 9 months after curative resection. Discussion and conclusion Laparoscopic surgery for inguinal hernia enables to observation of the inguinal region and management of rare cases, such as retroperitoneal liposarcoma.

Background: Cryptorchidism or undescended testis is an evolutionary defect where one or both testes fail to descend into the scrotum. HCG causes the testes to fail, possibly due to weight gain, an increase in testicular vasculature, and stimulating the testosterone and di-hydro-testosterone. The present study has been conducted to evaluate the therapeutic effects of HCG on patients with unilateral cryptorchidism. Methods: In a prospective descriptive study, 211 patients of 8 months to 7 years old with unilateral cryptorchidism whose parents refused surgery received HCG therapy. The patients were followed up 1 month, 3months, and 12 months after the first injection. They were examined in terms of the location of testes, possible relapses, sides of undescended testes, treatment complications, and HCG therapeutic results. Results: Four weeks after the first injection, 160 patients (75.12%) out of 211 cases had the descent of testes into the inguinal canal and the scrotum. 69.5% of non-palpable abdominal testes descended into the inguinal canal, 69.7% of patients with inguinal testes, 78% of patients with supra inguinal testes and 100% of patients with retractile testis experienced the descent of testes into the scrotum. Conclusion: The therapeutic response to HCG was successful in more than 50% of the cases in all the groups. Therefore, the need for performing surgical procedures on children with unilateral cryptorchidism would be decreased and they can be treated by a cost-effective and less invasive method. Moreover, at least one-year follow-up of the patients is required to ensure outcomes of the treatment.

Laparoscopic triple neurectomy is an available treatment option for chronic groin pain, but a poor working knowledge of the retroperitoneal neuroanatomy makes it an unsafe technique. Describe the retroperitoneal course of iliohypogastric, ilioinguinal, lateral femoral cutaneous and genitofemoral nerves, to guide the surgeon who operates in this region. Fifty adult cadavers were dissected resulting in 100 anatomic specimens. Additionally, 30 patients were operated for refractory chronic inguinal pain, using laparoscopic triple neurectomy. All operations and dissections were photographed. Measurements were made between the nerves of the lumbar plexus and various landmarks: interneural distances in a vertical midline plane, posterior or anterior iliac spine and branch presentation model. The ilioinguinal and iliohypogastric nerves were independent in 78% (Type II) and separated by an average of 2.5 ± 0.8 cm. In surgery study, only 38% were recognized as Type II and at a significantly greater distance (3.5 ± 1.2 cm, p

Introduction: Cyst of Nuck in women is a rare development disorder corresponding to hydrocoele of the spermatic cord in males; it can be associated with inguinal hernia in 30-40% of cases. Only 400 cases have been described in literature and in there are no older than 50. Case Presentation: A 62-year-old presented a right aching inguinal swelling. On physical examination the mass was not reducible, without signs of incarceration or strangulation. On ultrasound the lesion was mostly hypoechoic. CT saw an over liquid lesion, confirmed on MRI as a lesion hypointense in T1 and hyperintense in T2. The patient underwent open surgery: the cyst was separated from the round ligament and excised in mass and the defect was repaired with a prolene mesh. The histopathological exam confirmed the hydrocoele (calretinin positive, mesothelial cells on the inner surface). Discussion: The canal of Nuck is a small evagination of the parietal peritoneum that accompanies the round ligament into the inguinal canal during the first year of female development and is normally obliterated in the first year of life. Failure of obliteration of Nuck canal results in a hydrocoele that could develop intraabdominal or extra – abdominal or both. Ultrasound shows a thin walled, well defined, echo free cystic structure but the perfect diagnosis is given by MRI. Therapy is surgical and it can be open or, more recently, laparoscopic, depending on the expertise of the surgeon. Conclusion: A cyst of Nuck is a rare condition but it should always be considered in differential diagnosis of cystic inguinal lumps in women. Most of the reported cases concern children and young men. To our knowledge this is the only case regarding a more than 50-year-old.

Purpose Inguinal lymphadenectomy in penile cancer is associated with a high rate of wound complications. The aim of this trial was to prospectively analyze the effect of an epidermal vacuum wound dressing on lymphorrhea, complications and reintervention in patients with inguinal lymphadenectomy for penile cancer. Patients and methods Prospective, multicenter, randomized, investigator-initiated study in two German university hospitals (2013–2017). Thirty-one patients with penile cancer and indication for bilateral inguinal lymph node dissection were included and randomized to conventional wound care on one side (CONV) versus epidermal vacuum wound dressing (VAC) on the other side. Results A smaller cumulative drainage fluid volume until day 14 (CDF) compared to contralateral side was observed in 15 patients (CONV) vs. 16 patients (VAC), with a median CDF 230 ml (CONV) vs. 415 ml (VAC) and a median maximum daily fluid volume (MDFV) of 80 ml (CONV) vs. 110 ml (VAC). Median time of indwelling drainage: 7 days (CONV) vs. 8 days (VAC). All grade surgery-related complications were seen in 74% patients (CONV) vs. 74% patients (VAC); grade 3 complications in 3 patients (CONV) vs. 6 patients (VAC). Prolonged hospital stay occurred in 32% patients (CONV) vs. 48% patients (VAC); median hospital stay was 11.5 days. Reintervention due to complications occurred in 45% patients (CONV) vs. 42% patients (VAC). Conclusions In this prospective, randomized trial we could not observe a significant difference between epidermal vacuum treatment and conventional wound care.

Objectives The groin is a complex anatomic region that has traditionally been ignored by radiologists because most lesions can be diagnosed from clinical data and physical examination. Nevertheless, ultrasound examinations of the groin are increasingly being requested to confirm injury or to resolve diagnostic uncertainty. On the other hand, some conditions involving the groin are found only in paediatric patients. This article describes the key imaging findings in paediatric groin injuries, placing special emphasis on the ultrasound appearance. Conclusions Knowledge about conditions that can affect the groin in paediatric patients and the key imaging findings associated with them helps improve the diagnostic performance of ultrasound.
