Background: Acute right colic diverticulitis (ARD) is less frequent in Western countries than acute sigmoid diverticulitis (ASD). We aimed to compare the management of ARD and ASD operated on in emergency., Methods: All consecutive patients who had emergency surgery for ASD and ARD (2010-2021) were included in a retrospective, multicenter, cohort study. Patients were identified from databases in French centers that were members of the French Surgical Association. Emergency surgery was performed during the same hospitalization for peritonitis or after failure of conservative treatment. Early and late postoperative outcomes were studied., Results: A total of 2297 patients were included with 2256 (98.2%) ASD and 41 (1.8%) ARD patients. Baseline characteristics were similar. Overall, patients were rated Hinchey 3-4 (63.9%, n = 1468, p = 0.287). ARD was more often treated with resection and anastomosis, protected or not (53.7%, n = 22), whereas ASD was mainly treated with resection and terminal ostomy (62.5% (n = 1409), p < 0.001). Median operative time was shorter for ARD (120 vs 146 min, p = 0.04). The group of ARD patients showed a higher prevalence of Clavien III/IV complications compared to the group of ASD patients, although no statistically significant difference was observed (41.5%, n = 17 vs. 27.6%, n = 620, p = 0.054). However 90-day mortality only happened in ASD patients (9.8%, n = 223 vs 0, p = 0.03). ARD patients had more diverticulitis recurrence (46.3%, n = 19 vs 13.4%, n = 303, p < 0.001). Multivariate analysis identified female sex as a protective factor for recurrence [odds ratio (OR) 0.55, p < 0.001] and ARD as a risk factor (OR 8.85, p < 0.001)., Conclusion: Operated on in emergency, ARDs have more resection anastomosis, with a similar rate of complications, less mortality, and more recurrence of diverticulitis than ASD., (© 2024.

Introduction: Historically, colon resection was recommended after one episode of complicated diverticulitis. However, current trends favor a more individualized approach. This review examines elective sigmoidectomy for complicated diverticulitis as well as robotic approaches for diverticular disease. Methods: The literature was reviewed for timely (post 2000) and relevant articles regarding robotics and diverticulitis. The articles included large prospective series, retrospective analysis, meta-analyses and randomized controlled trials. Results: Primary anastomosis with or without protective ileostomy has emerged as an alternative to the Hartman's procedure in emergent or urgent surgery in patients without significant comorbidities. Elective sigmoidectomy after an episode of complicated diverticulitis should be decided on a case-by-case basis considering patient characteristics, continued subacute symptoms, complications from the disease, and chance of recurrence episodes. Conclusions: There are several variations techniques for robotic sigmoidectomy outlined in this article, and familiarity with all can help depending on the logistics of the case. Minimally invasive colectomy provides superior patient satisfaction and outcomes.

Background: There is an increasing demand for automated surgical skill assessment to solve issues such as subjectivity and bias that accompany manual assessments. This study aimed to verify the feasibility of assessing surgical skills using a surgical phase recognition model., Methods: A deep learning-based model that recognizes five surgical phases of laparoscopic sigmoidectomy was constructed, and its ability to distinguish between three skill-level groups-the expert group, with a high Endoscopic Surgical Skill Qualification System (ESSQS) score (26 videos); the intermediate group, with a low ESSQS score (32 videos); and the novice group, with an experience of < 5 colorectal surgeries (27 videos)-was assessed. Furthermore, 1 272 videos were divided into three groups according to the ESSQS score: ESSQS-high, ESSQS-middle, and ESSQS-low groups, and whether they could be distinguished by the score calculated by multiple regression analysis of the parameters from the model was also evaluated., Results: The time for mobilization of the colon, time for dissection of the mesorectum plus transection of the rectum plus anastomosis, and phase transition counts were significantly shorter or less in the expert group than in the intermediate (p = 0.0094, 0.0028, and < 0.001, respectively) and novice groups (all p < 0.001). Mesorectal excision time was significantly shorter in the expert group than in the novice group (p = 0.0037). The group with higher ESSQS scores also had higher AI scores., Conclusion: This model has the potential to be applied to automated skill assessments., (© 2024.

Here we report a 60-year-old male with a polypoid lesion due to sigmoid diverticulitis treated by endoscopic double-band ligation without resection. The method offers a safe, simple and effective way for polypoid lesions caused by diverticulitis and avoids the risk of perforation.

Background: Perineal proctosigmoidectomy (Altemeier) is a surgical procedure that is commonly used for the treatment of rectal prolapse. However, there is a diverse range of recurrence rates after Altemeier procedure repair that has been reported in the literature., Objective: To identify primary and subsequent recurrence rates after perineal proctosigmoidectomy and to define potential risk factors for recurrence., Design: Cohort study., Settings: Conducted at 6 hospitals affiliated with the Cleveland Clinic., Patients: The study included patients who were older than 18 years and were treated with the Altemeier procedure for rectal prolapse between 2007 and 2022., Main Outcome Measures: Primary outcomes were rates of primary and subsequent recurrences. Secondary outcomes included potential risk factors for recurrence previously mentioned in the literature., Results: We identified 182 patients, of whom 95.1% were women, with a mean age of 79 years (SD 11.4). Overall, procedures were elective in 92.1% of patients, and 14.3% had previously undergone prolapse repairs (Delorme, Thiersch, abdominal suture rectopexy, and abdominal mesh rectopexy). At a mean follow-up period of 27.5 months (SD 45.7), 37.9% of patients experienced recurrence, with 16.5% of patients having multiple recurrences. A subsequent Altemeier procedure was performed in 72.5% of instances. Other treatments included Delorme, abdominal suture rectopexy, abdominal mesh rectopexy, or conservative management. This study identified connective tissue disorders and time since surgery as significant risk factors for recurrence., Limitations: Retrospective design and varying follow-up periods., Conclusions: Perineal proctosigmoidectomy is associated with a significant risk of recurrence. The risk of recurrence increased with the presence of a connective tissue disorder and in proportion to the elapsed time since surgery. These discoveries assist health care professionals in counseling and managing patients who undergo perineal proctosigmoidectomy for rectal prolapse.

Introduction and Importance: Large bowel obstruction caused by volvulus poses a life-threatening risk without immediate intervention. Sigmoid colon volvulus is predominant (43-75%), followed by cecal volvulus 10-52%). Synchronous double colonic volvulus is extremely rare, with limited documented cases in academic literature., Case Presentation: We report a case of synchronous volvulus involving the sigmoid colon and cecum in a 45-year-old male of the Toro tribe from Fort Portal city in western Uganda who presented with acute abdominal pain, distension, and complete constipation for 2 days, accompanied by five episodes of non-bloody feculent vomiting and anorexia., Clinical Discussion: Upon admission, the patient presented with stable vital signs and a mildly tender, tympanic, distended abdomen with absent bowel sounds. Plain radiographs revealed the characteristic "coffee bean" sign, indicative of sigmoid volvulus. Following optimization, laparotomy confirmed synchronous volvulus involving both the sigmoid and cecum. Subsequently, a total colectomy with end ileostomy was performed, after which the patient experienced an uneventful recovery., Conclusion: Synchronous double colonic volvulus, a rare condition, is frequently overlooked clinically. Timely recognition and intervention are crucial to address diagnostic challenges and prevent potentially fatal outcomes., (© 2024. The Author(s).)

Introduction: Although recurrent diverticulitis appears to be a chronic relapsing disease from a clinical standpoint, there are no sufficient data about inflammatory markers that allow monitoring recurrent diverticulitis in the quiescent phase. Our hypothesis is that serum inflammatory markers may be increased during clinical quiescent phases of diverticulitis and will drop after elective laparoscopic sigmoidectomy for uncomplicated recurrent diverticulitis. We also believe that a drop in IL-6 levels across surgery could be related to an improved quality of life. Material and Methods: This epidemiological study aims to evaluate IL-6 serum levels and quality of life preoperatively and 6 months after surgery in 30 patients undergoing elective laparoscopic sigmoidectomy for uncomplicated recurrent diverticulitis. Results: The mean preoperative IL-6 level was 9.5 Ã+- 9.2 pg/ml (range 0-5), while at six months after surgery the mean IL-6 was 4.5 +- 3.5. (p=0.0085). Preoperative QoL measured with the GIQLI questionnaire was 98 +- 11.3 and raised significantly after surgery to 112 +- 9.8 (p=0.043). Conclusions: We found a serum IL-6 reduction after elective laparoscopic sigmoidectomy that can be attributed to the surgical removal of the source of inflammation in patients suffering from uncomplicated recurrent diverticulitis. Similarly, the GIQLI questionnaire showed a significantly improved QoL after surgery., (Celsius.)

The sigmoid colon simulator was designed to accurately reproduce the anatomical layer structure and the arrangement of characteristic organs in each layer, and to have conductivity so that energy devices can be used. Dry polyester fibers were used to reproduce the layered structures, which included characteristic blood vessels, nerve sheaths, and intestinal tracts. The adhesive strength of the layers was controlled to allow realistic peeling techniques. The features of the Sigmaster are illustrated through a comparison of simulated sigmoidectomy using Sigmaster and actual surgery. We developed a laparoscopic sigmoidectomy simulator called Sigmaster. Sigmaster is a training device that closely reproduces the membrane structures of the human body and allows surgeons to experience the entire laparoscopic sigmoidectomy process., (© 2024.

Low-grade appendiceal mucinous neoplasm (LAMN) is principally characterized by low-grade cytology without evidence of invasion to other organs. We report a LAMN surgical case whose appendiceal tumor penetrated the sigmoid colon wall. An 87-year-old man was referred for endoscopic resection (ER) of a colon polyp. Despite four ERs over 5 years, the polyp recurred at the same site. Laparoscopic surgery revealed a dilated appendix firmly attached to the sigmoid colon. We performed en bloc resection of both the sigmoid colon and appendix without tumor exposure. The histopathological evaluation showed that the LAMN had penetrated the sigmoid colon wall, forming two polyps on the colonic mucosa. In cases where the appendiceal-colonic fistula is suspected, en bloc resection of the appendix and colon wall should be considered., (© 2024 Asia Endosurgery Task Force and Japan Society of Endoscopic Surgery and John Wiley & Sons Australia, Ltd.)

An 87-year-old man experiencing lower abdominal discomfort resulting from the ingestion of a fish bone underwent conservative management involving endoscopic extraction of the fish bone lodged in the sigmoid colon. Most patients with lower gastrointestinal tract perforations typically develop peritonitis or abscesses, necessitating surgical intervention. Notably, endoscopic management of lower gastrointestinal tract perforations is infrequently employed. Patients presenting with localized abdominal symptoms along with a stable overall health condition may benefit from conservative therapeutic approaches that utilize endoscopic methods. Notably, the transition from endoscopic procedures for foreign body removal to surgical intervention requires close collaboration with a surgeon and must be executed judiciously.

Background: One of the approaches to distal sigmoid colon cancer surgical treatment is segmental colonic resection with vascular preservation of left colic artery (LCA). D3 lymph node dissection may technically vary according to different vascular anatomy. This study aims to show the approaches to D3 lymph node dissection with LCA preservation for distal sigmoid colon cancer according to different patterns of inferior mesenteric artery (IMA) branching., Methods: CT angiography with 3D reconstruction was routinely performed to identify the IMA branching pattern. Laparoscopic distal sigmoid colon resection with D3 lymph node dissection and left colic artery preservation in standardized fashion was performed in all cases. Data, including clinical, intraoperative, and short-term surgical outcomes, is presented as median numbers (Me) and interquartile range (IQR)., Results: Twenty-six patients with distal sigmoid colon cancer were treated with laparoscopic distal sigmoid colon resection. The approach to D3 lymph node dissection varied according to different anatomical variations. There was one conversion (3.8%) and one anastomotic leakage (3.8%) in patients with high BMI. At the same time, there was a high apical lymph node count (Me 3 (IQR 2-5), min-max 0-10) due to the skeletonization of the IMA., Conclusions: The technical aspects of D3 lymph node dissection with left colic artery preservation may vary in different types of LCA and sigmoid artery branching patterns regardless of the standardized anatomical landmarks. The anatomical features should be considered when performing vascular-sparing lymph node dissection., (© 2024. Springer Nature Switzerland AG.)

Purpose: Divided sigmoidostomy (DS) is the classic stoma for patients with anorectal malformations (ARM). Loop sigmoidostomies (LS) in ARM are associated with a higher risk of stoma prolapse and urinary tract infections (UTI). This is not clearly supported by literature. We compared our experience with both techniques., Methods: Retrospective study of ARM patients who underwent DS or LS between 2013 and 2023. We analysed demographics, associated malformations, intraoperative variables, oral intake and stoma functioning times, hospital stay, complications, prolapses, and UTI., Results: Of 40 patients, 29 underwent open DS and 11 laparoscopic LS. Demographics, malformation type, associated anomalies, surgical time, intraoperative and anaesthetic complications were comparable. Postoperative complications were higher in DS than LS [14(48.3%) vs 1(9.1%), (p = 0.02)], mostly due to wound complications [12(41.3%) vs 0(0%), (p = 0.01)]; with 3 dehiscenses and 3 strictures reintervened. The hours to oral intake and stoma functioning were higher for DS [48(39-90) and 48(24-48) vs 24(24-48) and 24(24-24), (p < 0.05)], with more days of hospital stay [36(19-60) vs 8(5-10), (p = 0.001)]. Prolapses [1(3.4%) vs 1(9.1%)] and UTIs [3(10.3%) vs 1(9.1%) (p > 0.05)] were comparable., Conclusion: LS in ARM patients have no higher risk of prolapse or UTI than DS. DS had more complications, mostly wound infections, strictures and dehiscenses., (© 2024. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.)

Background: Robotic three-dimensional magnified visual effects and field of view stabilization have enabled precise surgical operations. Intracorporeal anastomosis in right-sided colorectal cancer surgery is expected to shorten operation times, avoid paralytic ileus, and shorten wound lengths; however, there are few reports of intracorporeal anvil fixation for intestinal anastomosis in left-sided colorectal cancer surgery. Herein, we introduce a simple, novel procedure for using robotic purse-string suture (RPSS) in intracorporeal anastomosis with the double-stapling technique in rectal and sigmoid cancer surgery and report short-term outcomes., Methods: From September 2022 to April 2024, 105 consecutive patients underwent robotic surgery with double-stapling technique anastomosis for rectal or sigmoid colon cancer at our institution. Their data were retrospectively analyzed. Intracorporeal anastomosis with the double-stapling technique using RPSS was performed in 26 patients (the RPSS group), while the double-stapling technique anastomosis with extracorporeal anvil fixation was performed in 79 patients (the EC group). A 1:1 propensity score-matched analysis was performed (matching criteria: sex, age, body mass index (BMI), tumor location and tumor size) using a caliper 0.3. In the RPSS group, after tumor-specific or total mesorectal excision, specimens were extracted from the umbilical wound with simultaneous anvil placement in the body cavity. The oral colonic stump was robotically excised and robotically circumferentially stitched with 3-0 Prolene in all layers. After anvil insertion into the stump, the bowel wall of the colon was completely sewn onto the central rod of the anvil. Reconstructions were anastomosed using the double-stapling technique., Results: The matched cohort contained 23 patients in each group. The RPSS group had significantly less bleeding than the EC group (p = 0.038). Super-low anterior resection (SLAR) in the RPSS group had shorter total operative times than those in the EC group (p = 0.045). The RPSS group experienced no perioperative complications greater than Clavien-Dindo grade III or any anastomosis-related complications., Conclusions: The RPSS technique can be performed safely without any anastomosis-related complications and reduces the total operative times in SLAR and blood loss through total robotic surgery. This may be a useful modality for robotic colorectal surgery., (© 2024. The Author(s).)

Introduction and Hypothesis: Congenital cervicovaginal agenesis in the presence of a functional endometrium is a rare Müllerian anomaly. The management ranges from hysterectomy historically to various reconstructive procedures more recently. We report our experience with utero-colo-vaginoplasty in the management of this anomaly and its long-term follow-up., Methods: The case records of all the patients with vaginal or cervicovaginal agenesis in our hospital from January 2002 to December 2019 were reviewed retrospectively. The patients were then called for an outpatient visit and examined in detail. The anatomical variations, surgical procedures and outcomes were recorded and analysed., Results: Sixteen patients aged 14 to 26 years were included during the study period. They presented with cyclical painful cryptomenorrhea. Magnetic resonance imaging (MRI) confirmed cervicovaginal or distal vaginal agenesis. All the patients underwent utero-colo-vaginoplasty. Intraoperative rectal injury led to post-operative faecal leak from the perineal wound in one patient in the post-operative period. Restoration of painless menstrual flow was possible in all 16 cases. Long-term complications were seen in 4 patients. These were stenosis of the perineal neovaginal orifice in 2 patients, obstruction at colo-uterine anastomosis in 1 patient and mucosal prolapse at the neovagina in 1 patient. Three of these patients needed secondary surgical procedures. Five were sexually active and reported consummation of penetrative intercourse. None of them had conceived., Conclusion: In our experience, utero-colo-vaginoplasty allows for regular painless menstruation and coitus with minimal long-term complications. The sole disadvantage is the failure to conceive., (© 2024. The Author(s).)

Background: About 70% of women affected by ovarian cancer experience relapse within 2 years of diagnosis. Traditionally, the standard treatment for recurrent ovarian cancer (ROC) has been represented by systemic chemotherapy. 1 Recently, several retrospective studies have suggested that secondary cytoreductive surgery could provide better clinical outcomes than chemotherapy alone, in the case of complete tumor cytoreduction. 2,3 About 50% of patients with ROC have a pelvic component of the disease and 22% of patients present isolated pelvic recurrence, often involving the rectum. 4,5 Minimally invasive secondary cytoreductive surgery is a feasible option and is associated with favorable perioperative outcomes. 6-8 It is crucial to fully explore the peritoneal cavity before starting cytoreductive procedures in order to confirm the absence of carcinomatosis. 9 The robotic system facilitates the identification of anatomical structures and makes it easier to perform complex surgical steps in narrow spaces. It also allows the integrated use of surgical tools such as intraoperative ultrasound and indocyanine green application., Methods: In this video, we present the case of a 64-year-old woman who experienced a rectal recurrence of ovarian cancer after a platinum-free interval of 12 months. We describe, in a step-by-step manner, the surgical procedure of a robotic rectosigmoid resection with totally intracorporeal colorectal anastomosis (TICA). 10-12 RESULTS: Robotic secondary cytoreduction with complete gross resection was achieved. The patient did not report any intraoperative or postoperative complications. Final histology confirmed ROC., Conclusion: Totally robotic rectosigmoid resection is a feasible option in isolated bowel recurrences. Thanks to continuous technical evolution, robot-assisted surgery has the potential to have a central role in the fight against solid tumors. Integration of multiple pre- and intraoperative technologies allows personalized surgery to be performed for each different patient. 13,14 ., (© 2024. The Author(s).)

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., (© 2024.

Background and Aims: Recently, the location-based resect-and-discard (LBRD) strategy, which does not depend on optical diagnosis, was developed and demonstrated different surveillance interval agreement with the pathology-based reference in several researches. We aimed to evaluate the performance of LBRD in our first-time colonoscopy cohort, and improve the LBRD., Methods: The first-time colonoscopy with complete pathologic information were enrolled. The accuracy of LBRD strategy applied in diminutive polyps in different colonic segments was used as indicator to develop modified LBRD (mLBRD) strategy. Surveillance interval agreement with pathology-based reference was compared between LBRD and mLBRD. The ≥ 90% agreement with pathology was used as benchmark., Results: The polyps in sigmoid colon were significantly associated with higher proportion of neoplastic compared with polyps in rectum. The accuracy of LBRD applied in polyps in sigmoid colon were only 53.5%, which was significantly lower than that applied in polyps in other colonic segments. Thus, we hypothesized that mLBRD requiring pathology examination of diminutive polyps in sigmoid colon was more efficient in clinical use. The mLBRD significantly outperformed LBRD in surveillance interval agreement with pathology-based reference (90.2% vs. 83.4%, P <0.001), had lower proportion of patients assigned a longer surveillance interval (3.6% vs. 10.5%, P <0.001) and reached the benchmark, although the proportion of patients with an immediate surveillance interval recommendations and pathology examination avoided decreased., Conclusions: The mLBRD, but not LBRD, achieved sufficient surveillance interval agreement with pathology-based surveillance interval assignment and reduced over 30% of pathology examinations., (Copyright © 2023 Wolters Kluwer Health, Inc.

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.

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.

Although the safety and short-term outcomes of robotic surgery for sigmoid colon and rectal cancer patients are well-documented, there is limited research on the long-term survival outcomes of robotic colorectal surgery. This is a retrospective study that includes 502 patients who underwent either laparoscopic or robotic anterior resection and abdominoperineal resection for rectal or sigmoid colon cancer between August 2016 and September 2021. All patients were diagnosed with rectal or sigmoid colon adenocarcinoma. Propensity score matching (PSM) was implemented to minimize selection bias. Perioperative outcomes, complication rates, and pathological data were evaluated and compared. The 5-year overall survival rate and disease-free survival rate were calculated and compared. Before matching, patients in the robotic group had earlier pathological T and N stages and were more likely to have received neoadjuvant chemoradiotherapy compared to the laparoscopic group. After matching, most clinicopathological outcomes were similar between the two groups, but the robotic group had longer operative times and a lower conversion rate to open surgery compared with laparoscopic group. After matching for clinical factors, the 5-year DFS rates were 88.19% for the robotic group and 82.46% for the laparoscopic group (P = 0.122), and the OS rates were 90.5% and 79.5% (P = 0.342), showing no significant differences. In the stratified analysis, patients in the robotic surgery group had significantly higher 5-year DFS rates in the following subgroups: age < 65 years, TNM stage I-II, received neoadjuvant therapy, and primary tumor located in the rectum. The safety and efficacy of robotic surgery for sigmoid colon and rectal cancer were validated compared to laparoscopic surgery, with both groups of patients exhibiting comparable long-term prognoses., (© 2024.

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., (© 2024.

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., (© 2024.

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., (© 2024. The Author(s).)

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., Competing Interests: Competing interests: Dr Leitao reports personal fees from Medtronic, Intuitive Surgical, J&J/Ethicon, and Immunogen. Dr Abu-Rustum reports research funding paid to the institution from GRAIL. Memorial Sloan Kettering Cancer Center also has equity in GRAIL.

Objective: To evaluate the long-term effectiveness and consequences of augmentation cystoplasty in adult patients with small capacity bladder due to genitourinary tuberculosis (GUTB)., Methods: After approval of the institutional ethical committee, we retrospectively analyzed the database of adult patients with small capacity bladder due to GUTB treated by augmentation cystoplasty from January 2010 to December 2022 at our center. The patients were followed up at 6 weeks postoperatively, then every 3 months for first year and 6 months in second year, and then annually. Patients were assessed for symptoms, renal function, blood biochemistry levels, and ultrasound KUB at each follow-up visit., Results: A total of 40 patients underwent augmentation cystoplasty were included. All patients underwent augmentation cystoplasty either with ileum (n = 35) or sigmoid colon (n = 5). On long-term follow-up, there was statistically significant improvement in bladder capacity, decrease in voiding frequency (P = .00), decrease in eGFR (P = .02) and increase in serum creatinine (P = .02). Significant complications were wound infection 4 (10%), intestinal obstruction 1(2.5%), urinary tract infection 6 (15%), bladder stone 2 (5%), mucus retention 3 (7.5%), hypocalcemia with metabolic acidosis 2 (5%) and need of intermittent catheterization in 11 (27.5%) patients., Conclusion: Multidrug therapy with judicious reconstructive surgery is the optimal treatment modality for GUTB with cicatrization sequelae. In GUTB, augmentation cystoplasty is a safe procedure and strict long-term follow-up is needed to prevent complications., Competing Interests: Declaration of Competing Interest The authors declare that they have no conflict of interest., (Copyright © 2024 Elsevier Inc.

Introduction: Colon volvulus is the twisting of a segment of colon on its mesenteric axis, which can lead to the obstruction of the lumen and the blood supply. Colon volvulus is common in "volvulus belt" countries and can involve the sigmoid (60-70%) and cecum (25-40%)., Case Presentation: We report a case of a 47-year-old male, Alawites, who presented with bowel obstruction and dilated abdomen without any specific abdominal pain. Abdominal laparotomy showed both sigmoid and cecum volvulus with no signs of perforation or ischemia., Discussion and Conclusion: One of the possible risk factors of sigmoid colon volvulus is the length of the rectum and sigmoid, while mobile cecum is considered as a possible reason for cecum volvulus. The management remains controversial and is specific for every case, depending mainly on the vitality of the colonic walls and the general condition of the patient., (© 2024. The Author(s).)

To analyze the risk factors for intraperitoneal sigmoid stoma complications after abdominoperineal resection (APR) surgery to guide clinical practice. Patients who were diagnosed with rectal cancer and underwent APR surgery from June 2013 to June 2021 were retrospectively enrolled. The characteristics of the stoma complication group and the no stoma complication group were compared, and univariate and multivariate logistic analyses were employed to identify risk factors for sigmoid stoma-related complications. A total of 379 patients who were diagnosed with rectal cancer and underwent APR surgery were enrolled in this study. The average age of the patients was 61.7 ± 12.1 years, and 226 (59.6%) patients were males. Patients in the short-term stoma complication group were younger (55.7 vs 62.0, P < .05) and had a more advanced tumor stage (P < .05). However, there was no significant difference between the long-term stoma complication group and the no stoma complication group. Multivariate logistic regression analysis revealed that operation time was an independent risk factor (P < .05, OR = 1.005, 95% CI = 1.000-1.010) for short-term stoma complications. Both the short-term and long-term stoma complication rates in our institution were low. A longer operation time was an independent risk factor for short-term stoma complications after APR surgery., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2024 the Author(s).

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., (© 2024.

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.

BACKGROUND Laparoscopic-perineal neovagina construction by sigmoid colpoplasty is a popular therapeutic approach for patients with Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome. The conventional approach requires an auxiliary abdominal incision to exteriorize the descending colon to fix the anvil for end-to-end colorectal anastomosis. We modified the natural orifice specimen extraction surgery (NOSES) approach by exteriorizing the descending colon through the artificial neovaginal tunnel to replace the anvil extracorporeally, without requiring an auxiliary abdominal incision. It was a more minimally invasive technique. CASE REPORT We performed this modified laparoscopic-perineal sigmoid colpoplasty in a 26-year-old woman with MRKH syndrome. We cut off a segment of the sigmoid colon with a vascular pedicle to make a new vagina out of it, the same as in the traditional laparoscopic-perineal sigmoid colpoplasty. What is new about this technique is that it has no need for abdominal incision and is more minimally invasive. The operating time was 315 min. No postoperative complications occurred. The postoperative hospital stay was 4 days. The modified laparoscopic-perineal approach, free from an auxiliary abdominal incision, demonstrated advantages, including a shorter hospital stay, expedited recovery, and comparable anatomical outcomes, when compared with the traditional approach. This innovation improves the surgical experience for patients with MRKH syndrome, addressing the physical and psychological aspects of their condition. CONCLUSIONS This refined laparoscopic-perineal neovagina construction by sigmoid colpoplasty represents a feasible and minimally invasive technique. It is an attractive option for MRKH syndrome patients in need of vaginal reconstruction, offering a streamlined procedure with reduced postoperative recovery time and enhanced patient outcomes.

Vaginoplasty using sigmoid colon is a common technique used for the creation of a neovagina. However, the risk of adverse neovaginal bowel events is a common mentioned disadvantage. We report the case of a woman submitted to intestinal vaginoplasty for Mayer-Rokitansky-Küster-Hauser (MRKH) Syndrome at the age of 24 years who, with the onset of menopause, developed blood-stained vaginal discharge. Almost simultaneously, the patients complained chronic abdominal pain in lower left quadrant and prolonged diarrhea. General exams, Pap smear test, microbiological tests and viral test for HPV were negative. Neovaginal biopsies were suggestive for inflammatory bowel disease (IBD) of moderate activity and colonic biopsies were suggestive for ulcerative colitis (UC). The development of UC in the sigmoid neovagina and, almost simultaneously, in the remaining colon with onset of menopause raises important questions about etiology and pathogenesis of these diseases. Our case suggests that menopause may consider a trigger for the development of UC, due to the changes in the colon surface permeability related to menopause.

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., (© 2024 The Authors.

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., (© 2024.

Background: The role of neoadjuvant chemotherapy (NAC) in advanced sigmoid colon carcinoma remains to be further characterized. Rationale for NAC includes downstaging on final pathology and optimization of microscopically negative margins (R0 resection). We investigated rates of neoadjuvant chemotherapy use in advanced sigmoid colon cancer at academic cancer centers and assessed factors associated with likelihood of NAC administration., Methods: The National Cancer Database was queried from 2004 to 2017 for patients with clinical T3 or T4, N0-2, M0 sigmoid colon cancer who underwent surgical resection. Those with neoadjuvant radiation or metastatic disease were excluded. The outcomes of patients who did and did not receive neoadjuvant chemotherapy were evaluated for this retrospective cohort study., Results: There were 23,597 patients of whom 364 (1.5%) received NAC. More patients received NAC at academic (41%, P < .001) and high-volume centers (27%, P < .001). Patients with Medicare/Medicaid (39%) and private insurance (52%) were more likely to receive NAC ( P < .001). There was a significantly higher rate of N2 to N1 downstaging in the NAC group. Propensity-score matching demonstrated comprehensive community cancer programs (CCCP) were less likely to provide NAC (OR 0.4; 95% CI 0.23, 0.70, P < .001). There was no difference in survival ( P = .20), R0 resection ( P = .090), or 30-day readmission rates ( P = .30) in the NAC cohort compared to the non-NAC cohort., Conclusions: Access to centers offering multi-disciplinary care with NAC prior to surgical resection is important. This care was associated with academic and high-volume centers and private or government-sponsored insurance. There was no difference in survival between NAC and non-NAC cohort., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

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., (© 2024.
