Risk factors for emergency surgery for diverticulitis: A retrospective multicentric French study at 41 hospitals.

BACKGROUND: The observed increase in the incidence of complicated diverticulitis may lead to the performance of more emergency surgeries. This study aimed to assess the rate and risk factors of emergency surgery for sigmoid diverticulitis. METHOD: The primary outcomes were the rate of emergency surgery for sigmoid diverticulitis and its associated risk factors. The urgent or elective nature of the surgical intervention was provided by the surgeon and in accordance with the indication for surgical treatment. A mixed logistic regression with a random intercept after multiple imputations by the chained equation was performed to consider the influence of missing data on the results. RESULTS: Between 2010 and 2021, 6,867 patients underwent surgery for sigmoid diverticulitis in the participating centers, of which one-third (n = 2317) were emergency cases. In multivariate regression analysis with multiple imputation by chained equation, increasing age, body mass index <18.5 kg/m2, neurologic and pulmonary comorbidities, use of anticoagulant drugs, immunocompromised status, and first attack of sigmoid diverticulitis were independent risk factors for emergency surgery. The likelihood of emergency surgery was significantly more frequent after national guidelines, which were implemented in 2017, only in patients with a history of sigmoid diverticulitis attacks. CONCLUSION: The present study highlights a high rate (33%) of emergency surgery for sigmoid diverticulitis in France, which was significantly associated with patient features and the first attack of diverticulitis.

Management of adult intestinal stomas: The 2023 French guidelines.

AIM: Digestive stoma are frequently performed. The last French guidelines have been published twenty years ago. Our aim was to update French clinical practice guidelines for the perioperative management of digestive stoma and stoma-related complications. METHODS: A systematic literature review of French and English articles published between January 2000 and May 2022 was performed. Only digestive stoma for fecal evacuation in adults were considered. Stoma in children, urinary stoma, digestive stoma for enteral nutrition, and rare stoma (Koch, perineal) were not included. RESULTS: Guidelines include the surgical landmarks to create digestive stoma (ideal location, mucocutaneous anastomosis, utility of support rods, use of prophylactic mesh), the perioperative clinical practice guidelines (patient education, preoperative ostomy site marking, postoperative equipment, prescriptions, and follow-up), the management of early stoma-related complications (difficulties for nursing, high output, stoma necrosis, retraction, abscess and peristomal skin complications), and the management of late stoma-related complications (stoma prolapse, parastomal hernia, stoma stenosis, late stoma retraction). A level of evidence was assigned to each statement. CONCLUSION: These guidelines will be very useful in clinical practice, and allow to delete some outdated dogma.

Is early CT in cases of elevated postoperative CRP the best option for the diagnosis of colorectal anastomotic leakage?

PURPOSE: After colorectal surgery (CRS), the early detection and treatment of anastomotic leakage (AL) is critical. We aimed to evaluate the efficacy of early contrast-enhanced computed tomography (CT) (postoperative day [POD] 2-3) after elective colorectal surgery for the diagnosis of AL for patients with elevated CRP levels at POD 2-3. METHOD: From 2017 to 2022, all patients who underwent elective CRS with an anastomosis and CRP > 150 mg/ml on POD 2-3 underwent enhanced CT during the 24 h following the CRP evaluation and were included in this retrospective, single-center study. The primary endpoint was the diagnostic value of the early CT scan for the detection of AL. The secondary endpoints were the diagnostic value of the early CT scan for the detection of grade C AL according to the type of resection and anastomosis and the quality of the opacification. RESULTS: A total of 661 patients underwent elective CRS with anastomosis with an overall AL rate of 7.4%. Among the 661 patients, 141 were finally included in the study. The accuracy of early CT for the diagnosis of AL was 83.7%. For grade C AL, the accuracy was 81.6%. Among patients who had an ileocolic anastomosis, the accuracy was 88.2%, among those who had colorectal or ileorectal anastomosis, the accuracy was 83.0%, and among those who had a coloanal, the accuracy was 66.7%. In cases of good opacification by CT, the accuracy was 84.0%. CONCLUSION: Early CT does not show perfect accuracy for an early diagnosis of AL.

Risk factors for ischemia/necrosis of the colonic stump after proctectomy and delayed coloanal anastomosis.

INTRODUCTION: Delayed coloanal anastomosis (DCAA) is a two-stage procedure. DCAA has been increasingly reused in recent years in the management of rectal cancer. Such increased use of DCAA has highlighted the complications associated with this procedure. We aimed to evaluate the risk and risk factors of ischemia/necrosis of the colonic stump between the two stages of DCAA. PATIENTS AND METHODS: All patients who underwent a proctectomy with a DCAA were included in this retrospective single-centre study from November 2012 to June 2022. Two groups of patients were defined: patients with a well vascularized colonic stump (well vascularized group) and those who experienced ischemia or necrosis of the colonic stump (ischemic group). The primary endpoint was the rate of ischemia or necrosis of the colonic stump and an evaluation of the associated risk factors. RESULTS: During the study period, 43 patients underwent DCAA. Amongst them, 32 (75%) had a well-vascularized colonic stump (well-vascularized group) and 11 (25%) ischemia of the colonic stump (ischemic group). Relative to patients in the well-vascularized group, those in the ischemic group were more often men (81.8% vs 40.6%, p = 0.034), had a higher BMI (29.2 kg/m2 vs 25.7 kg/m2, p = 0.03), were more frequently diabetic (63.6% vs 21.9%, p = 0.01) and more frequently had had preoperative radiotherapy (100% vs 53.1%, p = 0.008). On the preoperative CT scan, the interspinous diameter was shorter in the ischemic group (9.4 ± 1.01 cm vs 10.6 ± 1.01 cm, p = 0.001), the intertuberosity diameter was shorter (9.2 ± 1.18 cm vs 11.9 ± 1.18 cm, p < 0.0001), and the length of the anal canal was longer (31.9 ± 3 mm vs 27.4 ± 3.2 mm, p < 0.0001). CONCLUSION: This study highlights clear risk factors for ischemia/necrosis of the colonic stump after proctectomy with DCAA.

Purse string closure of perineal defects after abdominoperineal excision.

PURPOSE: The aim of this study was to describe a new technique of perineal closure following abdominoperineal excision (APE) using purse-string perineal skin closure (PSPC). MATERIAL AND METHODS: Between January 2016 and May 2021, 15 consecutives patients who had an APE procedure were included in this retrospective single-center study. All indications of APE were considered, as well as all types of APE. We analyzed the patient characteristics and peri-operative features, including overall (Clavien 1 to 5) and severe (Clavien 3 and 4) postoperative morbidity, length of stay (LOS), and long-term results (median time to perineal wound closure and rate of perineal incisional hernia). RESULTS: The patients included 11 men and four women, with a mean age of 64 ± 13 [33-80] years. The indication of APE was an epidermoid carcinoma of the anal canal (n = 5) or an adenocarcinoma of the rectum (n = 10). The mean operating time was 220 ± 88.64 [70-360] min. The overall morbidity rate was 60%, the severe morbidity rate 26%, and reoperation rate 26%. The median length of stay was 9 ± 6.5 days. After a mean follow-up of 23.5 ± 20.3 months, the median time to perineal wound closure was 96 ± 60 days, the persistent perineal sinus rate was 6% (n = 2), and one patient developed a perineal incisional hernia. CONCLUSION: Purse-string closure of perineal wounds is a safe and effective technique for perineal wound closure after APE. The short LOS allowed an early return home.

Quality of life after sigmoid diverticulitis: A review.

INTRODUCTION: Diverticular disease, including diverticulitis, begins when the patient becomes symptomatic. Sigmoid diverticulitis corresponds to inflammation/infection of a diverticulum of the sigmoid colon. Among diverticulosis patients, 4.3% develop diverticulitis, a frequent pathology that can entail major functional disorders. Following sigmoid diverticulitis, few studies have assessed functional disorders and quality of life, a multidimensional concept comprising physical, psychological and mental dimensions, as well as social relations. OBJECTIVE: The purpose of this work is to report current published data on the quality of life of patients having had sigmoid diverticulitis. RESULTS: Following uncomplicated sigmoid diverticulitis, long-term quality of life does not substantially differ between patients having undergone antibiotic therapy and those having only received symptomatic treatment. As for patients having experienced recurrent events, their quality of life seems improved by elective surgery. Following Hinchey I/II sigmoid diverticulitis, elective surgery seems to improve quality of life, notwithstanding a 10% risk of postoperative complications. Following sigmoid diverticulitis, while emergency surgery seems not to have greater impact on quality of life than elective surgery, the surgical technique employed in an emergency setting seems to have an impact, particularly with regard to the physical and mental components of quality of life. CONCLUSION: Assessment of quality of life is of fundamental importance in diverticular disease and should orient operative indications, particularly in an elective context.

Is a Defunctioning Stoma Necessary After Left Colectomy in High-risk Patients for Anastomotic Leak?

INTRODUCTION: Left colectomy is associated with a 7% risk of anastomotic leak. In 2011, a prediction score for AL [the colon leakage score (CLS)] was developed. The aim was to evaluate the impact of a defunctioning stoma on AL and its consequences after left colectomy in high-risk patients. PATIENTS: From January 2012 to June 2019, high-risk patients who underwent a left colectomy with anastomosis were included in this retrospective, single-center study. Two groups of patients were defined: patients undergoing a left colectomy with an anastomosis without a defunctioning stoma (no-stoma group) and those with a defunctioning stoma (stoma group). The primary endpoint was the rate of anastomotic leakage. RESULTS: Ninety-two patients were included in this study. The anastomotic leakage rate was 16.4% in the no-stoma group and 21.6% in the stoma group ( P =0.5). A conservative approach was applied to 11.2% in the no-stoma group and 50% in the stoma group ( P =0.1). The severe morbidity rate was 14.5% in the no-stoma group and 21.6% in the stoma group ( P =0.4). The rate of unplanned admissions was 7% in the no-stoma group and 27% in the stoma group ( P =0.01). CONCLUSION: A defunctioning stoma does not appear to reduce the rate of AL in high-risk patients, but its impact on the management of AL remains unclear.
