Multidisciplinary surgical management of severe posterior compartment endometriosis.

BACKGROUND: Endometriosis is a chronic, inflammatory, and hormone-dependent disease that affects approximately 10% of women in reproductive age. Endometriosis is categorized into different types, as superficial, deep, and ovarian endometriosis. When deep endometriosis occurs, the sigmoid and rectum are often affected (Becker et al. in Hum Reprod Open, 2022, https://doi.org/10.1093/hropen/hoac009 ). In the following article, we aim to demonstrate stepwise surgery for stage IV endometriosis involving the anterior rectosigmoid. METHODS: We present the case of a 26-year-old obese (BMI 35.87) woman with severe posterior pelvic compartment endometriosis, persistent abdominal pain, and constipation. On preoperative MRI of the pelvis, a 13 cm conglomerate incorporating both ovaries (kissing ovaries), uterine serosa, and the anterior rectosigmoid was observed (Fig. 1). Accordingly, interdisciplinary laparoscopic surgery with a gynecologist and colorectal surgeon was planned. RESULTS: The total laparoscopic approach is demonstrated step by step in the video. CONCLUSIONS: Deep endometriosis is a rare condition. When involvement of other organs (e.g., the bowel) is suspected, preoperative endometriosis-specific imaging should be performed for optimal surgical planning. Experienced endometriosis multidisciplinary surgical teams can provide specialized and high-quality care for patients suffering from this debilitating disease (Luna Russo et al. in Minerva Ginecol, 2020, https://doi.org/10.23736/S0026-4784.20.04544-X ).

Sigmoid and cecum colon volvulus: a case report.

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.

Transvaginal ultrasound with bowel preparation versus transvaginal ultrasound with bowel preparation and water contrast for diagnosing Recto-Sigmoid endometriosis. A systematic review and Meta-Analysis.

Transvaginal ultrasound is effective in diagnosing endometriosis involving the rectosigmoid bowel. Some authors suggest enhanced detection of rectosigmoid involvement with bowel preparation. Conversely, conflicting views argue that bowel preparation may not improve diagnostic precision, yielding similar results to rectal water contrast. No existing meta-analysis compares these approaches. Our study aims to conduct a meta-analysis to evaluate the diagnostic performance of transvaginal ultrasound with bowel preparation, with and without rectal water contrast. Studies published between 2000 and 2023 were searched in PubMed, Scopus, Cochrane and Web of Science. From 561 citations, we selected nine studies to include in this meta-analysis. The study quality was assessed using QUADAS-2 (Quality Assessment of Diagnostic Accuracy Studies-2). The mean prevalence of endometriosis rectosigmoid was 43.6% (range 17,56-76,66%) in the group with bowel preparation and 64,80% (50,0-83,60%) for the group with bowel preparation and rectal water contrast. Pooled sensitivity and specificity were 93% and 94% for bowel preparation and 92% and 95% and for bowel preparation with water contrast. We conclude that, there was no significant difference between performing transvaginal ultrasound with intestinal preparation with and without water contrast. In clinical practice, the absence of a significant difference between these methods should be taken into account when making recommendations.

Feasibility of Intraoperative Proctosigmoidoscopy After Discoid Bowel Resection for Deep Infiltrating Endometriosis: A Pilot Multicenter Study.

STUDY OBJECTIVE: Although surgery is the gold standard treatment for pain refractory to medical management or partial occlusion owing to rectosigmoid endometriosis, surgical resection can be associated with major perioperative complications. From general surgery experience, intraoperative proctosigmoidoscopy has shown encouraging results as a feasible, safe, and effective technique in reducing the risk of complications related to intestinal anastomosis after segmental resection. Unfortunately, there are no studies evaluating its role after discoid resection for rectosigmoid endometriosis. DESIGN: A pilot, multicentric, observational, prospective, cohort study. SETTING: Two academic hospitals, from March 1 to December 31, 2022. PATIENTS: We enrolled all consecutive fertile-age patients affected by symptomatic endometriosis scheduled for laparoscopic discoid bowel resection. Inclusion criteria were (1) age between 18 and 50 years, (2) diagnosis of rectosigmoid endometriosis performed by transvaginal ultrasound and/or magnetic resonance imaging, and (3) women scheduled for laparoscopic discoid bowel resection of endometriosis at low risk of segmental resection. INTERVENTIONS: During data analysis, enrolled patients were divided into 2 study groups for comparisons based on whether or not the intraoperative proctosigmoidoscopy was performed upon surgeons' discretion after discoid resection for treating endometriosis, in addition to standard integrity tests. Primary outcome was the rate of intraoperative proctosigmoidoscopy success. Secondary study outcomes were the differences between the intraoperative proctosigmoidoscopy group and the nonintraoperative proctosigmoidoscopy group in (1) mean of total operative time and (2) rate of perioperative complications. MEASUREMENTS AND MAIN RESULTS: A total of 28 patients were enrolled and equally distributed in the 2 groups. The rate of intraoperative proctosigmoidoscopy success was 86%. No significant difference was reported between the 2 groups in terms of total operative time (p = .1) and intraoperative and postoperative complications (p = .5 and p = 1, respectively), with no surgical complication related to intraoperative proctosigmoidoscopy. CONCLUSION: Intraoperative proctosigmoidoscopy seems as a feasible and non-time-consuming intraoperative procedure in women undergone discoid resection for rectosigmoid endometriosis. Larger studies with longer follow-up period are necessary to confirm our findings and assess clinical benefits over standard procedure.

Management of Recurrent Sigmoid Volvulus in the Pediatric Population.

Sigmoid volvulus is a rare etiology of bowel obstruction in the pediatric population that can be easily misdiagnosed, leading to delayed treatment and potential complications. Given that sigmoid volvulus is a common cause of bowel obstruction in the adult population and the significant lack of literature on its management in children, treatment strategies for pediatric patients often follow standardized protocols for adults. We report the case of a 15-year-old boy who presented with recurrent episodes of sigmoid volvulus over a 1-month period. Computed tomography demonstrated a sigmoid volvulus without evidence of ischemia or bowel infarction. Colonoscopy demonstrated a descending megacolon, and bowel transit studies demonstrated normal transit time. Acute episodes were managed conservatively with colonoscopic decompression. After a complete study, laparoscopic sigmoidectomy was performed. This work demonstrates the importance of early recognition and treatment of sigmoid volvulus in the pediatric population to limit recurrent episodes.

Sigmoid volvulus management, only endoscopic devolvulation?

Intestinal obstruction due to sigmoid volvulus (SV) represents a relevant percentage of abdominal diseases presenting at the emergency department. Treatment is based on early endoscopic devolvulation (ED), followed by elective surgery as definitive treatment. A 78-year-old man institutionalized with Lewy body dementia presents with abdominal pain, distention, and absence of stool in 72 hours. Coffee bean sign was seen in abdominal x-ray. Previously, he had been admitted three times last year with recurrent SV, managed with ED succesfully. Despite the recurrence, no surgical treatment was indicated after resolution of the acute situation and recovery of intestinal transit. This time, urgent colonoscopy was performed and a 20 cm length of purplish-black (isquemic) sigmoid mucosa was observed. With these findings of stablished intestinal ischemia urgent surgical intervention was performed (sigmoidectomy and terminal "Hartmann" colostomy). Histologically, necrosis, severe ulceration and mixed inflammation was noticed in the surgical piece. The patient develops favorably during a postoperative period without incidents. Therefore, he is discharged to his center. At the moment he is asymptomatic one year after the intervention with no new episodes. Recurrency of SV after ED is up to 86% of cases. In every episode, the incidence of complications such as intestinal ischemia or perforation increases significantly, as well as urgent surgery and mortality. Definitive treatment must be surgical, sigmoidectomy and terminal anastomosis is the choice technique.

Intestinal pneumatosis as a manifestation of systemic sclerosis.

A 60-year-old female patient was admitted to the emergency room for a 7-day history of abdominal bloating, nausea, vomiting, constipation, and lack of flatus. She had been diagnosed with systemic sclerosis (SSc) 10 years ago and had been using methotrexate, sildenafil, and prednisone. She did not present any signs of instability, but physical examination showed malnourishment status and abdominal tenderness and distention. Plain abdominal radiography was suggestive of sigmoid volvulus, confirmed and successfully resolved after endoscopic decompression therapy. Eight months later, the patient developed a new episode of abdominal obstruction. Computed Tomography (CT) scan identified a distended sigmoid colon due to its torsion with gas areas within the bowel wall. This time, endoscopic decompression had failed to treat, so exploratory laparotomy was performed. Colonic distention and sigmoid volvulus were identified during the procedure, after which sigmoidectomy followed by primary anastomosis was performed. Neither perforation nor masses were found. Furthermore, the anatomopathological study was inconsistent with vascular, inflammatory, or neoplastic diseases.

Non-invasive treatment of sigmoid volvulus in a child. The role of the endoscopist.

Sigmoid volvulus (SV) is a rare cause of intestinal obstruction in children. Its varied presentation and rapid progression engender a high risk of morbidity and mortality. We report two cases of SV in teenage boys. Patient 1 is 16 years old and patient 2 is 17. Both presented to our institution with recent-onset abdominal pain, constipation, and nausea and vomiting, and both had previous episodes of SV. Patient 1 had been surgically treated with manual derotation, and patient 2, who had redundant colon, had two past episodes of endoscopically-treated SV. Both patients were in poor condition and had distended but treatable abdomens, with no peritoneal signs. After computed tomography (CT) confirmation of the clinical impression of no ischemia or perforation, we decided to attempt detorsion of the SV and decompression of proximal dilated colon by flexible endoscopy, and planned for elective surgery shortly after the endoscopic procedure. Because sigmoid volvulus is so rare in children, operative and technical details of endoscopic management are gleaned from the larger adult experience. In patients without signs of complication, initial endoscopic reduction is the gold standard, and elective sigmoid resection with primary anastomosis is often required to prevent recurrence.

Management of sigmoid volvulus during labor : a challenging situation.

Acute intestinal obstruction is rare during pregnancy. Its diagnosis is difficult because the symptoms can be minimal and mimic signs of a regular pregnancy. Sigmoid volvulus is a common cause of these obstructions. The management is challenging because it depends on many factors, and affects maternal-fetal outcomes. We report a case of a 32-year-old woman with sigmoid volvulus associated with fetal demise that came during labor and we discuss the management options.

Stratification of sigmoid volvulus early recurrence risk using a combination of CT features.

PURPOSE: The purpose of this study was to identify computed tomography (CT) features associated with early recurrence of sigmoid volvulus (SV) after a first uncomplicated episode and to develop a score for early SV recurrence risk stratification. MATERIALS AND METHODS: A total of 95 patients (59 men, 36 women; mean age, 72 ± 15 [SD] years; age range: 57-87 years) who underwent abdominal CT examination for a first uncomplicated SV episode from January 1st 2006 to July 31st 2020 in two French University Hospitals were retrospectively included. A SV recurrence occurring within six months was defined as early SV recurrence. CT findings associated with SV were searched for using univariable analysis. CT features associated with early recurrence were computed into a multivariable logistic regression model that was further used to build a score to stratify SV recurrence risk. Kaplan-Meier curves were built to evaluate recurrence-free survival. RESULTS: Early SV recurrence occurred in 53 patients (56%). At multivariable analysis, left lateral section volume < 150 cm3 and maximal colon distension > 10 cm were associated with early SV recurrence (Odds ratio [OR] = 4.62; 95% CI: 1.77-13.33; P = 0.002 and OR = 4.43 95% CI: 1.63-13.63; P = 0.005) respectively), and an early SV recurrence score with 1 point attributed to each of these two variables was built. Early SV recurrence was observed in 26%, 54% and 89% of patients with score of 0, 1 and 2, respectively (P < 0.001). CONCLUSION: A simple CT score allows stratification of early SV recurrence after a first episode and helps to select patient who would not benefit from prophylactic colonic surgery because of a low SV recurrence risk.
