RESUMEN
BACKGROUND: Creation of a tension-free colorectal anastomosis after left colon resection or low anterior resection is a key requirement for technical success. The relative contribution of each of a series of known lengthening maneuvers remains incompletely characterized. OBJECTIVE: The aim of this study was to compare technical procedures for lengthening of the left colon before rectal anastomosis. DESIGN: A series of lengthening maneuvers was performed on 15 fresh cadavers. Mean distance gained was measured for each successive maneuver, including 1) high inferior mesenteric artery ligation, 2) splenic flexure takedown, and 3) high inferior mesenteric vein ligation by the ligament of Treitz. SETTING: Cadaveric study. MAIN OUTCOME MEASURES: The premobilization and postmobilization position of the proximal colonic end was measured relative to the inferior edge of the sacral promontory. Measurements of the colonic length relative to the sacral promontory were taken after each mobilization maneuver. The inferior mesenteric artery, sigmoid colon, and rectum specimen lengths were measured. The distance from the inferior border of the sacral promontory to the pelvic floor was measured along the sacral curvature. RESULTS: Mean sigmoid colon resection length was 34.7 ± 11.1 cm. Before any lengthening, baseline reach was -1.3 ± 4.2 cm from the sacral promontory. Inferior mesenteric artery ligation yielded an additional 11.5 ± 4.7 cm. Subsequent splenic flexure takedown added an additional 12.8 ± 9.6 cm. Finally, inferior mesenteric vein ligation added an additional 11.33 ± 6.9 cm, bringing the total colonic length to 35.7 ± 14.7 cm. BMI and weight negatively correlated with length gained. LIMITATIONS: The study was limited by nature of being a cadaver study. CONCLUSIONS: Stepwise lengthening maneuvers allow significant additional reach to allow a tension-free left colon to rectal anastomosis. See Video Abstract . ESTUDIO CADAVRICO DE MANIOBRAS DE ALARGAMIENTO COLNICO TRAS UNA SIGMOIDECTOMA: ANTECEDENTES:La creación de una anastomosis colorrectal libre de tensión tras una resección de colon izquierdo o tras una resección anterior baja es un requisito clave para el éxito relacionado con la técnica quirúrgica. La relativa contribución de las diversas maniobras de alargamiento permanece caracterizada de manera incompleta.OBJETIVO:El propósito de este estudio fue la de comparar procedimientos técnicos de alargamiento del colon izquierdo previo a la anastomosis rectal.DISEÑO:Una serie de maniobras de alargamiento fueron realizados en 15 cadáveres frescos. La distancia promedio ganada fue medida para cada maniobra sucesiva, incluyendo (1) ligadura alta de la arteria mesentérica inferior, (2) descenso del ángulo esplénico, (3) ligadura alta de la vena mesentérica interior mediante el ligamento de Treitz.AJUSTES:Estudio cadavérico.PRINCIPALES MEDIDAS DE RESULTADO:La posición premobilizacion y postmobilizacion del extremo proximal del colon fue medido tomando en cuenta el borde inferior del promontorio sacro. Las mediciones de la longitud colónica en relación al sacro fueron tomadas luego de cada maniobra de movilización. Fueron tomadas así mismo las longitudes de la arteria mesentérica inferior, el colon sigmoides y recto. Las distancias desde el borde inferior del promontorio sacro al suelo pelvico fueron medidas a lo largo de la curvatura sacra.RESULTADOS:Average sigmoid colon resection length was 34.7 ± 11.1 cm. Prior to any lengthening, baseline reach was -1.3 ± 4.2 cm from the sacral promontory. Inferior mesenteric artery ligation yielded an additional 11.5 ± 4.7 cm. Subsequent splenic flexure takedown added an additional 12.8 ± 9.6 cm. Finally, inferior mesenteric vein ligation added an additional 11.33 ± 6.9 cm, bringing the total colonic length to 35.7 ± 14.7 cm. BMI and weight negatively correlated with length gained.LIMITACIONES:Este estudio tuvo como limitación la naturaleza de haber sido un estudio cadavérico.CONCLUSIONES:Maniobras de alargamiento permiten un alcance adicional significativo permitiendo de esta manera una anastomosis de colon izquierdo a recto libre de anastomosis.

BACKGROUND: Sex reassignment surgery (SRS) is a necessary step in transitioning into the desired gender for male-to-female transgender individuals. This study focuses on a rare complication developed following SRS, aiming to highlight potential complications associated with this procedure. CASE PRESENTATION: This report describes a 49-year-old transgender woman with a history of SRS who developed bloody diarrhea and neovaginal bleeding 10 years later. A colonoscopy revealed features compatible with ulcerative colitis, which was confirmed by a biopsy. CONCLUSIONS: The unpredictable clinical course of this phenomenon may prompt surgeons to reconsider the use of a rectosigmoid colon to create a neovagina. This case report underscores the necessity of long-term monitoring for gastrointestinal complications in transgender women post-SRS when a rectosigmoid colon segment is utilized for neovaginal construction.

BACKGROUND: The landscape of robotic surgery is evolving with the emergence of new platforms. However, reports on their applicability in different surgical fields are still limited and come from teams with robotics experience. This study aims to describe the training process for colorectal surgery with the Hugo™ RAS system of a robotics-inexperienced surgical team and present the initial patient series. METHODS: The training process is depicted, and data from the first 10 consecutive patients operated on for colorectal conditions with the Hugo™ RAS system by a surgical team with no prior experience in robotic surgery were prospectively recorded and analysed. RESULTS: The team received intensive training in robotic surgery and specifically in the Hugo™ RAS system previously to the first case. Between May 2023 and December 2023, 10 patients underwent colorectal procedures: 5 right colectomies, 3 sigmoid resections, 1 high rectal resection and 1 ventral mesh rectopexy. The first case was proctored by an expert. Median docking time was 14 min and median total operative time was 185 min. The only technical difficulty during the procedures was occasional clashing of robotic arms. None had to be converted, and no intraoperative or postoperative morbidity was recorded. Hospital stays ranged from 2 to 4 days. A median of 21 lymph nodes were yielded in the operations for malignant conditions. CONCLUSIONS: Common colorectal procedures can be safely performed using the Hugo™ RAS platform. Prior experience in robotic surgery is not a necessary requirement, but following a structured training program is essential.

BACKGROUND: Ovarian cancer with extensive metastatic disease involving pelvic structures often requires rectosigmoid resection for complete gross resection; however, it is associated with increased surgical morbidity. There are limited data, and none in ovarian cancer, on near-infrared assessment of perfusion in rectosigmoid resections with anastomosis. PRIMARY OBJECTIVE: To compare the rate of pelvic complications (pelvic abscesses, anastomotic leaks, and infections) within 30 days of surgery with and without near-infrared assessment of perfusion at time of rectosigmoid resection and re-anastomosis in patients undergoing cytoreductive surgery for ovarian cancer. STUDY HYPOTHESIS: We hypothesize the use of near-infrared technology (intravenous indocyanine green and endoscopic near-infrared fluorescence imaging), compared with standard intra-operative assessment, to evaluate anastomotic perfusion at time of rectosigmoid resection and re-anastomosis will result in lower rates of post-operative pelvic complications. TRIAL DESIGN: This is a planned multicenter randomized controlled trial. Patients who undergo rectosigmoid resection as part of their ovarian cytoreductive surgery will be randomized 1:1 to standard assessment of anastomosis with the surgeon's usual technique (control arm) or assessment with near-infrared angiography using indocyanine green and endoscopic fluorescence imaging (experimental arm). Randomization will occur after rectosigmoid resection has been completed and the surgeon declares their plan to create a diverting ostomy. Randomization will be stratified by plan for diverting ostomy. MAJOR INCLUSION/EXCLUSION CRITERIA: Main inclusion criteria include patients with primary or recurrent ovarian, fallopian tube, or primary peritoneal cancer who are scheduled for cytoreductive surgery with suspected need for low-anterior rectosigmoid resection. PRIMARY ENDPOINT: Rate of 30-day post-operative pelvic complications. SAMPLE SIZE: 310 (155 per arm) ESTIMATED DATES FOR COMPLETING ACCRUAL AND PRESENTING RESULTS: Q2 2027 and Q4 2027, respectively. TRIAL REGISTRATION: NCT04878094.

BACKGROUND: Sigmoid gallstone ileus is a rare complication of cholelithiasis, accounting for 1-4% of all cases of large-bowel obstruction. This is a highly morbid, and often fatal, condition due to its challenging diagnosis and late presentation. CASE PRESENTATION: We report a case of a 90-year-old woman admitted to Emergency Department with abdominal pain and large-bowel obstruction due to a 6 cm gallstone lodged in a diverticulum of the proximal sigmoid colon as a consequence of a cholecysto-colonic fistula. Colonoscopy was deferred due to gallstone size carrying a high possibility of failure. The patient underwent urgent laparotomy with gallstone removal via colotomy. The cholecystocolonic fistula was left untreated. The post-operative course was uneventful; the patient was discharged on 6th post-operative day. CONCLUSION: A multidisciplinary discussion between endoscopists and surgeons is often needed to choose the best therapeutic option, especially in high-risk patients.

BACKGROUND: There is limited data to guide decision-making between performing a primary anastomosis and fashioning an end colostomy following emergency sigmoid colectomy for patients with sigmoid volvulus. The aim of this study was to compare the outcomes of these two approaches. METHODS: The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database from 2006 to 2021 was retrospectively analyzed. Missing data were multiply imputed, and coarsened exact matching was performed to generate matched cohorts. Rates of major complications and other postoperative outcomes were evaluated among patients who had a primary anastomosis as compared with matched controls who had an end colostomy following emergency sigmoid colectomy. RESULTS: Overall, 4041 patients who had a primary anastomosis and 1240 who had an end colostomy met the inclusion criteria. After multiple imputation and coarsened exact matching, 895 patients who had a primary anastomosis had a matched control. The rate of major complications was lower in patients who had an end colostomy (33.2% vs. 36.7%), but this difference was not statistically significant (OR 0.86, 95% CI 0.70-1.05). Results were similar in subgroup analyses of higher-risk patients. There were no significant differences in overall complication rate, mortality, length of hospital stay, or readmission rate. Patients with a colostomy were more likely to be discharged to a care facility (OR 1.35, 95% CI 1.09-1.67). CONCLUSION: Differences in rates of major complications and many other outcomes after primary anastomosis as compared with end colostomy were not statistically significant following emergency sigmoid colectomy for sigmoid volvulus.

INTRODUCTION AND HYPOTHESIS: We investigate the feasibility, safety, and clinical therapeutic effect of laparoscopic sigmoid vaginoplasty in women with Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome. METHODS: We performed a retrospective case review cohort study of 56 patients with MRKHs undergoing laparoscopic sigmoid vaginoplasty in Wuhan Union Hospital between 2000 and 2020, and all patients were followed up. RESULTS: The median operating time was 165 min (120-420 min). The median hospital stay was 10 days (rang 7-15 days). A functional neovagina was created 11-15 cm in length and two fingers in breadth in all patients. No introitus stenosis was observed. No intra- or post-operative complications occurred. Two patients were lost to follow-up after 3 months of outpatient visits. Six patients had no intercourse and were required to wear a vaginal mold occasionally. None of the patients had complained of local irritation or dyspareunia. Patients who had post-surgery sexual intercourse were satisfied with their sexual life and the mean total Female Sexual Function Index (FSFI) score was 25.17 ± 0.63. The cosmetic results were excellent. CONCLUSIONS: The laparoscopic sigmoid vaginoplasty can achieve the goal of making a functional neovagina. The main advantage of this surgical technique is that it is minimally invasive and that there are fewer complications post-operation. It is an acceptable procedure for patients with MRKH syndrome.

PURPOSE: Robotic assisted surgery is an alternative, fast evolving technique for performing colorectal surgery. The primary aim of this single center analysis is to compare elective laparoscopic and robotic sigmoid colectomies for diverticular disease on the extent of operative trauma and the costs. METHODS: Retrospective analysis from our prospective clinical database to identify all consecutive patients aged ≥ 18 years who underwent elective minimally invasive left sided colectomy for diverticular disease from January 2016 until December 2020 at our tertiary referral institution. RESULTS: In total, 83 patients (31 female and 52 male) with sigmoid diverticulitis underwent elective minimally invasive sigmoid colectomy, of which 42 underwent conventional laparoscopic surgery (LS) and 41 robotic assisted surgery (RS). The mean C-reactive protein difference between the preoperative and postoperative value was significantly lower in the robotic assisted group (4,03 mg/dL) than in the laparoscopic group (7.32 mg/dL) (p = 0.030). Similarly, the robotic´s hemoglobin difference was significantly lower (p = 0.039). The first postoperative bowel movement in the LS group occurred after a mean of 2.19 days, later than after a mean of 1.63 days in the RS group (p = 0.011). An overview of overall charge revealed significantly lower total costs per operation and postoperative hospital stay for the robotic approach, 6058 vs. 6142 (p = 0,014) not including the acquisition and maintenance costs for both systems. CONCLUSION: Robotic colon resection for diverticular disease is cost-effective and delivers reduced intraoperative trauma with significantly lower postoperative C-reactive protein and hemoglobin drift compared to conventional laparoscopy.

BACKGROUND: In the decision to perform elective surgery, it is of great interest to have data about the outcomes of surgery to individualize patients who could safely undergo sigmoid resection. The aim of this study was to provide information on the outcomes of elective sigmoid resection for sigmoid diverticular disease (SDD) at a national level. METHODS: All consecutive patients who had elective surgery for SDD (2010-2021) were included in this retrospective, multicenter, cohort study. Patients were identified from institutional review board-approved databases in French member centers of the French Surgical Association. The endpoints of the study were the early and the long-term postoperative outcomes and an evaluation of the risk factors for 90-day severe postoperative morbidity and a definitive stoma after an elective sigmoidectomy for SDD. RESULTS: In total, 4617 patients were included. The median [IQR] age was 61 [18.0;100] years, the mean ± SD body mass index (BMI) was 26.8 ± 4 kg/m2, and 2310 (50%) were men. The indications for surgery were complicated diverticulitis in 50% and smoldering diverticulitis in 47.4%. The procedures were performed laparoscopically for 88% and with an anastomosis for 83.8%. The severe complication rate on postoperative day 90 was 11.7%, with a risk of anastomotic leakage of 4.7%. The independent risk factors in multivariate analysis were an American Society of Anesthesiologists (ASA) score ≥ 3, an open approach, and perioperative blood transfusion. Age, perioperative blood transfusion, and Hartmann's procedure were the three independent risk factors for a permanent stoma. CONCLUSIONS: This series provides a real-life picture of elective sigmoidectomy for SDD at a national level. TRIAL REGISTRATION: Comité National Information et Liberté (CNIL) (n°920361).

PURPOSE: To present the functional results after a transanal proximal rectosigmoidectomy in patients with severe idiopathic constipation in which medical treatment has failed. METHODS: Patients with severe idiopathic constipation who underwent transanal proximal rectosigmoidectomy (TPRS) at Children's Hospital Colorado between June 2019 and March 2024 were included in the study. We compared multiple pre- and post-operative outcome measures and the patient's bowel regimen before and after resection. RESULTS: Fourteen patients underwent TPRS, 10 of whom were male. The average age at the time of surgery was 10.1 years (range 5-19). Seven patients have moderate to severe autism. Constipation-related clinic visits, family calls, procedural intervention, emergency room visits, and hospitalizations notably decreased frequency after TPRS. Laxative dosages and enema volume requirements were also reduced after surgery. Before surgery, all the patients suffered from daily fecal accidents, while post-operatively, all were completely free of stool accidents. CONCLUSION: In our experience, for patients who suffer from severe medically refractory idiopathic constipation, TPRS has provided improvement in their symptoms and decreased the complications inherent to this chronic disease. Parents and patients attest to a profound positive transformation in their quality of life after surgery.

PURPOSE: We investigated whether inflammatory cell infiltration (ICI), fibrosis, and mitochondrial viability of the neurogenic bladder urothelium are involved in the mechanism of persistent vesicoureteral reflux (VUR) after sigmoidocolocystoplasty (SCP). METHODS: Bladder biopsies obtained 1994-2023 from 62 neurogenic bladder patients were examined by hematoxylin and eosin for ICI, Masson's trichrome for fibrosis, and immunofluorescence for urothelial growth differentiation factor 15 (GDF15; a mitochondrial stress-responsive cytokine) (positive/negative) and heat shock protein 60 (HSP60; a mitochondrial matrix marker) (strong ≥ 50%/weak≤ 50%) expression. GDF15 + /weak HSP60 indicated compromised mitochondrial viability. Cystometry measured neobladder compliance/capacity. RESULTS: Mean ages (years) at SCP and bladder biopsies were 9.4 ± 4.6 and 14.2 ± 7.1, respectively. VUR was present in 38/62 patients (51 ureters) at SCP and resolved with SCP alone in 4/38 patients, with SCP and ureteroneocystostomy in 17/38, and persisted in 17/38. Fibrosis was significantly denser in GDF15 + (n = 24)/weak HSP60 (n = 31) compared with GDF15- (n = 38)/strong HSP60 (n = 31) (p < 0.001 and p < 0.01, respectively). Differences in ICI were significant for GDF15 + vs. GDF15- (p < 0.05) but not for HSP60. Patients with VUR after SCP had higher incidence of GDF15 + /weak HSP60 compared with cases without VUR (p < 0.05 and p < 0.001, respectively). CONCLUSION: Viability of mitochondria appears to be compromised with possible etiologic implications for VUR persisting after SCP.

The rupture of an internal iliac artery aneurysm in the colon is a rare but potentially fatal complication. We report a rectal fistula of an asymptomatic internal iliac artery aneurysm that was discovered incidentally during a medical examination. A 77-year-old man presented at a local hospital for a general medical examination. Although the blood reports revealed severe anemia, the patient did not complain of any associated symptoms including dizziness and hematochezia. Moreover, there was no palpable mass in the patient's abdomen, and there was no evidence of hematochezia, as the patient had been using a bidet. Interestingly, computed tomography (CT) revealed a large right internal iliac artery aneurysm. There was a suspicious finding of a fistula within the colon in the CT, but it was undetected in the preoperative sigmoidoscopy. Furthermore, operative findings showed a protruding retroperitoneal mass adhering to the mesentery of the sigmoid colon. During aneurysm resection, the presence of a fistula was unclear. However, a fistula tract, devoid of any infectious bacteria such as tuberculosis, was found in the specimen after colon resection. After a recovery period of approximately one week, the patient was discharged from the hospital without any unusual findings on the post-operative CT. Sigmoid colonic fistulas arising from iliac artery aneurysms are rare. Also, diagnosis may be delayed in special circumstances wherein a patient routinely uses a bidet.

From 2006 to 2021, 27 patients who underwent stoma construction during colorectal cancer resection followed by stoma closure were grouped into 2 groups: Group A(7 patients with cancer)and Group B(20 patients without cancer). The male- to-female ratio were 6:1 for Group A and 13:7 for Group B. The average ages were 63.7 and 65.0 years, respectively. The ratios(Group A:Group B)of the causes for stoma construction were 5:13 for bowel obstruction due to colorectal cancer, 2:2 for abdominal wall invasion/dissemination and 0:5 for covering stoma. The causes of non-curative resection for Group A were peritoneal dissemination(4 patients), liver metastasis(1 patient), bladder infiltration(1 patient), and periaortic lymph node metastasis(1 patient). For Groups A and B, Hartmann surgery was performed in 4 and 10, colectomy and stoma construction in 3 and 5, and low anterior resection and covering stoma in 0 and 5 patients, respectively. The median time to stoma closure was 10 months for Group A and 6 months for Group B(p<0.05). There was no case of anastomotic leakage and 1 case of anastomotic stenosis(case not treated with anticancer drugs). No patient died of cancer within 1 year after stoma closure(median survival time after stoma closure was >26.0 months for Group A). Although stoma closure in patients with cancer was significantly delayed compared with patients without cancer, it was performed safely.

A 72-year-old male was transported to our hospital with complaints of heart palpitations and dyspnea since a month earlier and was immobile. Blood examination showed severe anemia, and colonoscopy revealed circumferential tumors in the rectum and the sigmoid colon. Histopathologic examination revealed the tumors as squamous cell carcinoma of the rectum and adenocarcinoma of the sigmoid colon. Therefore, they were diagnosed as double colorectal cancers. CT and MRI showed that rectal cancer invaded the seminal vesicles and the prostate; therefore, the patient underwent neoadjuvant chemoradiotherapy(oral capecitabine and concomitant radiation therapy: a total dose of 50.4 Gy/28 Fr)followed by total pelvic exenteration. Subsequent specimen pathology revealed a tumor regression grading of Grade 2 for the rectal and sigmoid colon cancers, and both were staged as ypT3N0M0, ypStage â ¡a. Herein, we report a rare case of double cancer of adenocarcinoma of the sigmoid colon and squamous cell carcinoma of the rectum with a literature review.
