Restoration of intestinal continuity following emergency sigmoid colectomy for sigmoid volvulus: An American College of Surgeons National Surgical Quality Improvement Program analysis using coarsened exact matching.

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.

Colorectal procedures with the novel Hugo™ RAS system: training process and case series report from a non-robotic surgical team.

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.

Like a Rolling (Gall)Stone: Optimal Treatment of Gallstone Obstruction of the Sigmoid Colon.

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.

Transgastric drainage for subdiaphragmatic abscess secondary to perforation of the sigmoid colon after cytoreductive surgery for advanced ovarian cancer.

Drainage of subdiaphragmatic abscesses is difficult due to its anatomical location and it can result in adverse events, including organ damage and the spread of infection. In recent years, endoscopic ultrasonography (EUS) guided drainage for upper abdominal abscesses has become available. We report a case of successful infection control using this procedure for a subdiaphragmatic cyst secondary to perforation of the sigmoid colon after cytoreductive surgery for advanced ovarian cancer. A Japanese woman in her 60s underwent laparotomy for ovarian cancer, and then developed sigmoid colon perforation 6 days after surgery. The emergency reoperation was performed, and a cyst suspected to be an antibiotic-resistant fungal abscess appeared under the left diaphragm in the postoperative period. We adopted an EUS-guided route for diagnostic and therapeutic drainage method, which enabled shrinkage of the cyst and did not concur further adverse events. This procedure was effective as a minimally invasive drainage route for subdiaphragmatic cysts.

Risk factors for severe morbidity and definitive stoma after elective surgery for sigmoid diverticulitis: a multicenter national cohort study.

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).

Compound volvulus: ileosigmoid knot.

Compound volvulus, also known as ileosigmoid knot, is a rare cause of intestinal obstruction due to twisting of the small bowel around the large bowel or vice-versa. It poses a diagnostic dilemma due to the presence of features of closed-loop obstruction of both the small and large bowel. Being a surgical emergency due to the rapid progression to gangrene of involved segments leading to septicaemia, early suspicion of the disease entity, adequate resuscitation and prompt treatment are the need of the hour. Three cases encountered and managed in our setting are described here with a review of the literature.

Sigmoid colonic metastasis from a squamous cell carcinoma of the cervix: A rare case report with literature review.

RATIONALE: As the third most common cancer in women, cervical cancer usually spreads to adjacent organs. Distant metastasis from the cervix to the gastrointestinal tract is an extremely rare occurrence. PATIENT CONCERNS: Herein, we present a rare case of a 57-year-old woman who was treated by hysterectomy and bilateral salpingo-oophorectomy with pelvic lymphadenectomy for squamous cell carcinoma (SCC) of the uterine cervix. A metastatic location in the sigmoid colon was revealed after 8 years causing an acute intestinal obstruction in this patient. DIAGNOSES: Final surgical pathology showed an invasive lesion with squamous differentiation in full thickness of the colon wall from mucosa to serosa. Meanwhile, the results of immunohistochemistry (IHC) showed the cancer cells were positive for CK5/6, P63, P40, and P16 confirming the diagnosis of metastatic sigmoid colonic carcinoma originating from SCC of the uterine cervix. INTERVENTIONS: Sigmoid colon resection with lymph node dissection followed by adjuvant chemotherapy (paclitaxel, carboplatin, and paprillizumab) was performed on the patient. OUTCOMES: The patient was disease-free 16 months after surgery. LESSONS SUBSECTIONS: SCC is one of the rare malignant tumors of the gastrointestinal tract occurring as either a primary or secondary lesion. However, the secondary SCC of the colon has a poorer prognosis compared with the primary SCC. Therefore, colonic metastasis must be considered in the differential diagnosis of acute intestinal obstruction, especially in patients with the medical history of SCC in other organs.

Nationwide Outcomes After Neoadjuvant Chemotherapy for Locally Advanced Sigmoid Colon Cancer-A Propensity Score-Matched Analysis.

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.

Fertility sparing double discoid excision of rectosigmoid deep endometriosis under robotic-integrated ultrasound guidance.

OBJECTIVE: To present the use of robotic-integrated ultrasound for performing a double discoid excision of multifocal rectosigmoid endometriosis. DESIGN: Video article. STATEMENT OF CONSENT: The patient included in this video gave consent for publication of the video and posting of the video online, including social media, journal website, scientific literature websites (such as PubMed, ScienceDirect, Scopus), and other applicable sites. PATIENT: A 26-year-old G0 woman with chronic pelvic pain, dyschezia, and dysmenorrhea refractory to medical management desired future fertility. Imaging was suggestive of deep infiltrating endometriosis involving the rectosigmoid colon. INTERVENTION: Not applicable. MAIN OUTCOME MEASURES: Double discoid excision of multifocal rectosigmoid endometriosis using robotic-integrated ultrasound. RESULTS: Not applicable. CONCLUSIONS: Performing a complete preoperative evaluation in patients with suspected endometriosis is important for determining the extent of disease and necessity of a multidisciplinary approach. Robotic-integrated ultrasound can provide additional information, including the size and depth of bowel endometriosis lesions, which can play a role in surgical decision making. Performing a double discoid excision of multifocal rectosigmoid endometriosis using robotic-integrated ultrasound is a technique that can avoid the need for a segmental bowel resection.

Long-Term Bowel Vaginoplasty With a Single Yang-Monti Tube.

INTRODUCTION: The bowel remains the favored tissue for neo-vaginoplasty (NeoVP) in pediatric patients with vaginal agenesis. In 2001, the first description of NeoVP using the Yang-Monti technique with a sigmoid double tubular flap was published. We present our experience of NeoVP with a single Yang-Monti tube (SYMT) flap and report on the use of different segments of colon. METHODS: We conducted a retrospective review of patients who underwent NeoVP using a bowel SYMT between 2009 and 2021. The procedure was performed under open abdominal surgery by isolating 8 to 12 cm from the rectosigmoid, cecum, or ascending colon. Subsequently, this segment was detubularized near the mesenteric border, folded, and retubularized transversally, leaving the mesentery in a cephalic position. A channel was dissected in the pelvis to accommodate the NeoVP. RESULTS: Seventeen patients were identified. The median age was 16 years old. The principal diagnosis was Mayer-Rokitansky's syndrome (47.1%). The median follow-up was 50 months. The mean harvested bowel length was 9 cm, and the sigmoid was the preferred site (65%). The cecum-ascending colon was used in 3 (17.6%) patients. Complications were recorded in 6 patients (35%). Of these 6 patients, 4 had introital stenosis. There was 1 case of urethrovaginal fistula and another of left hematometrocolpos. Satisfactory sexual function has been reported in sexually active individuals. CONCLUSIONS: We described our experience in NeoVP using a large bowel SYMT as a safe and effective technique. It allows decreased tension on the vascular pedicle and the use of shorter colon segments.
