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).

Long-term outcomes of Hartmann's procedure versus primary anastomosis for generalized peritonitis due to perforated diverticulitis: follow-up of a prospective multicenter randomized trial (DIVERTI).

BACKGROUND: Surgical management of Hinchey III and IV diverticulitis involves Hartmann's procedure (HP) or primary resection anastomosis (PRA) with or without fecal diversion. These procedures were evaluated in four randomized controlled trials. Early results from these trials demonstrated similar rates of complications but higher rates of colonic restoration after PRA than HP. Long-term follow-up has not been reported to date. The aim of this study was to analyze long-term outcomes and quality of life (QoL) in patients previously enrolled in a prospective randomized trial comparing HP and PRA for generalized peritonitis due to perforated diverticulitis (DIVERTI trial). STUDY DESIGN: Follow-up data were available for 78 of 102 patients. Demographic data, incisional hernia rate, need for additional surgery related to the primary procedure, and QoL were recorded. RESULTS: The overall survival rate was 76% and did not differ between the two groups. Incisional hernia was reported in 21 (52%) patients in the HP arm and in 11 (29%) patients in the PRA arm (p = 0.035). The HP arm demonstrated significantly lower SF-36 physical and mental component scores. The mean general QoL (EQ-VAS) and mean EQ-5D index scores were better after PRA than after HP, but this difference was not statistically significant. The results of GIQLI, which measures intestine-specific QOL, did not differ between the two groups. CONCLUSIONS: This follow-up study with a median follow-up time of > 9 years among living patients indicates that PRA for perforated diverticulitis is associated with fewer long-term complications and better QoL than HP. PRA significantly reduced the incisional hernia rate and the need for reoperation. Long-term survival was not jeopardized by the PRA approach. Future studies are needed to address the utility of protective stoma.

Innovative appliance for colostomy patients: an interventional prospective pilot study.

BACKGROUND: The control of body waste emptying is a constant research topic in stoma care. The aim of this pilot study was to assess the efficacy and safety of an innovative colostomy appliance. METHODS: An interventional prospective non-comparative pilot study was conducted in seven French centers. The study device is a new type of two-piece appliance including a base plate and a "capsule cap" (CC) composed of a capsule cover and a folded collecting bag. The device gently seals the stoma to provide stoma output control. When the bowel movement pressure increases the patient may control the deployment of the folded bag and collect stools. Patients with left-sided colostomy all using a flat appliance, were enrolled in a 2-week trial. Outcome measures were type of CC removal and peristomal fecal leaks while wearing the device. RESULTS: Of 30 patients (females 66.7%), with left-sided colostomy (permanent 76.7%), 23 (76.7%) completed the 2-week trial. A total of 472 CC changes were analyzed. EFFICACY: of 404 (85.5%) CC changes reported in diaries, 302 (74.8%) were linked with stool and/or gas. In 244 (60.3%) changes, the patient controlled stoma bag deployment and it occurred with bowel emptying 301 (74.5%) times. No leaks around the appliance were observed in 400 (85.3%) changes. SAFETY: no serious adverse event occurred. Peristomal skin was not modified during the trial. CONCLUSIONS: In the short term this new device has provided an increased control over bowel emptying at no risk in half of the trial population suggesting that an alternative approach to bag wearing is achievable.

Early removal of intraperitoneal drainage after pancreatoduodenectomy in patients without postoperative fistula at POD3: Results of a randomized clinical trial.

BACKGROUND: To determine whether the timing of removal of abdominal drainage (AD) after pancreatoduodenectomy (PD) influences the 30-day surgical site infection (30-day SSI) rate. METHODS: A multicenter randomized, intention-to-treat trial with two parallel arms (superiority of early vs. standard AD removal on SSI) was performed between 2011 and 2015 in patients with no pancreatic fistula (PF) on POD3 after PD (NCT01368094). The primary endpoint was the 30-day SSI rate. The secondary endpoints were specific post-PD complications (grade BC PF), postoperative morbidity and risk factor of SSI, reoperation rate, 30-day mortality, length of drainage, length of stay and postoperative infectious complications. RESULTS: One hundred and forty-one patients were randomized: 71 in the early arm, 70 in the standard arm (70.2% of pancreatic adenocarcinomas; 91.5% of pancreatojejunostomies; 66.0% of bilateral drainages; feasibility: 39.9%). Early removal of drains was not associated with a significant decrease of 30-day SSI (14.1% vs. 24.3%, P=0.12). A lower rate of deep SSI was observed in the early arm (2.8% vs. 17.1%, P=0.03), leading to a shorter length of stay (17.8±6.8 vs. 21.0±6.1, P=0.01). Grade BC PF rate (5.6%), severe morbidity (17.7%), reoperation rate (7.8%), 30-day mortality (1.4%) and wound-SSI rate (7.8%) were similar between arms. After multivariate analysis, the timing of AD removal was not associated with an increase of 30-day SSI (OR=0.74 [95% CI 0.35-1.13, P=0.38]). CONCLUSION: In selected patients with no PF on POD3, early removal of abdominal drainage does not seem to increase or decrease surgical site infection's occurrence.

What are the predictive factors of caecal perforation in patients with obstructing distal colon cancer?

AIM: In the presence of large bowel obstruction, the choice of treatment is determined by the patient's general status, the tumour characteristics and the perceived risk of caecal perforation. This study was designed to evaluate the predictive factors of impending caecal perforation, and also investigated the use of caecal volumetry. METHOD: From January 2011 to June 2016, patients with obstructive distal colon cancer undergoing emergency laparotomy, for whom a pretreatment CT scan was available, were included in this retrospective, case-control, two-centre study. Two patient groups were defined: patients with and without impending caecal perforation. The primary end-point of the study was a determination of predictive factors for caecal perforation. RESULTS: A total of 72 patients (45 men, 62.5%) were included. Univariate analysis revealed that the presence of pericaecal fluid (P < 0.0001), caecal pneumatosis (P < 0.0001), mean maximum caecal diameter (P = 0.001), mean caecal diameter at the ileocaecal junction (P = 0.0001) and mean caecal volume (P = 0.001) were associated with caecal perforation. Receiver operating characteristic curve analysis revealed that a caecal volume greater than 400 cm3 (P < 0.0001), a maximum caecal diameter > 9 cm (P = 0.002) and a caecal diameter at the ileocaecal junction > 7.5 cm (P = 0.001) were associated with impending caecal perforation. In multivariate analysis, only caecal volume > 400 cm3 (P = 0.001) was correlated with the risk of impending caecal perforation. CONCLUSION: Caecal volumetry is an easy and useful tool to predict impending caecal perforation in patients with large bowel obstruction.

[Dermatological features of auto-inflammatory recurrent fevers]. / Peau et fièvres récurrentes auto-inflammatoires.

Auto-inflammatory diseases are characterized by unexplained and recurrent attacks of systemic inflammation often involving the skin, joints, or serosal membranes. They are due to a dysfunction or dysregulation of the innate immunity, which is the first line of defense against pathogens. Early recognition of these diseases by the clinician, especially by pediatricians encountering such pathologies in pediatric patients, is primordial to avoid complications. Skin manifestations, common in most auto-inflammatory diseases, are helpful for prompt diagnosis. After a brief physiopathological review, we will describe auto-inflammatory recurrent fevers by their main dermatological presentations: urticarial lesions, neutrophilic dermatoses, panniculitis, other maculopapular eruptions, dyskeratosis, skin vasculitis, and oral aphthous. We finally suggest a decision tree to help clinicians better target genetic exams in patients with recurrent fevers and dermatological manifestations.

Serum procalcitonin correlates with colonoscopy findings and can guide therapeutic decisions in postoperative ischemic colitis.

BACKGROUND: Postoperative ischaemic colitis (POIC) is a life-threatening vascular gastrointestinal condition. Serum procalcitonin (PCT) levels be of value in the detection of necrosis. AIMS: To evaluate the correlation between serum PCT levels and the colonoscopic assessment of the severity of POIC. METHODS: Between January 2007 and November 2014, 150 patients with POIC and PCT data were included in the study. The main outcome measure was the correlation between serum PCT and the colonoscopy-based assessment of the severity of POIC (according to Favier's classification: stage 1/2 without multi-organ failure vs. stage 2/3 with multi-organ failure). RESULTS: Eighty-five percent of the stage 1 cases (n=22) had a serum PCT level ≤2µg/L; 63% (n=19) of the stage 2 cases with multi-organ failure had a PCT level between 4 and 8µg/L, and 70% (n=52) of the stage 3 cases had a PCT level ≥8µg/L. The PCT level was strongly correlated with the Favier stage (Spearman's rho: 0.701; p<0.0001). PCT levels were similar in stage 2 cases with multi-organ failure and in stage 3 cases (16.06µg/L vs. 7.79µg/L, respectively; p=0.35). CONCLUSION AND RELEVANCE: Serum PCT is correlated with stage 2/3 POIC requiring surgery. If PCT ≥5µg/L, surgery should be considered.

Pyopneumothorax and peritonitis due to perforated duodenal ulcer and associated pleuroperitoneal communication.

Pleuroperitoneal communication is an anatomic entity that is typically asymptomatic but sometimes responsible for hydrothorax. This pleural manifestation can be explained by progressive transdiaphragmatic passage of intra-abdominal fluid because of abdominal hyperpressure. The object of this report is to present a hitherto unreported association of concomitant pleural effusion and acute infectious abdominal disease, due to perforated duodenal ulcer. This underscores that pleural effusion associated with acute abdominal pain may reveal the existence of a communication of this type, and requires surgical management.

Colectomy in patients with previous colectomy or occlusive vascular diseases: Pitfalls and precautions.

Two principal branches from the aorta provide the colonic blood supply: the superior and inferior mesenteric arteries. There are numerous anatomical variations, which the surgeon must fully understand before embarking on any colonic surgery. A good knowledge of these variations is particularly important when the patient has already undergone colectomy or presents with occlusive vascular disease. The aim of this review is to summarize the standard anatomy and the main variations of the colonic blood supply as they apply to colorectal surgery in this setting.

Serum value of procalcitonin as a marker of intestinal damages: type, extension, and prognosis.

BACKGROUND: Ischemic and necrotic damages are complications of digestive diseases and require emergency management. Nevertheless, the decision to surgically manage could be delayed because of no sufficiently preoperative accurate marker of ischemia diagnosis, extension, and prognosis. METHODS: The aim of this study was to assess the predictive value of serum procalcitonin (PCT) levels for diagnosing intestinal necrotic damages, their extension, and their prognosis in patients with ischemic disease including ischemic colitis and mesenteric infarction by a gray zone approach. Between January 2007 to June 2014, 128 patients with ischemic colitis and mesenteric infarction (codes K55.0 and K51.9) were operated, for whom data on PCT were available. We perform a retrospective, multicenter review of their medical records. Patients were divided into subgroups: ischemia (ID group) versus necrosis (ND group); the extension [focal (FD) vs. extended (ED)] and the vital status [deceased (D) vs. alive (A)]. RESULTS: PCT levels were higher in the ND (n = 94; p = 0.009); ED (n = 100; p = 0.02); and D (n = 70; p = 0.0003) groups. With a gray zone approach, the predictive thresholds were (i) for necrosis 2.473 ng/mL, (ii) for extension 3.884 ng/mL, and (iii) for mortality 7.87 ng/mL. CONCLUSION: In our population, PCT could be used as a marker of necrosis; especially in case of extended damages and reflects the patient's prognosis.

Omental torsion, a rare cause of acute surgical abdomen.

Torsion of the greater omentum is a rare cause of acute abdominal pain. The symptoms of this pathology are non-specific and abdominal CT is usually necessary to make the diagnosis. Treatment is surgical and can often be performed laparoscopically.

Management of the perineal wound after abdominoperineal resection.

Although many options are available for the management of perineal wounds after abdominoperineal resection, ranging from direct closure to flap reconstruction, treatment remains challenging. A better understanding of the aims, drawbacks and progress in perineal wound management after abdominoperineal rectal resection can help the surgeon make better choices for each patient, but it is very difficult to propose a single, optimal, evidence-based procedure for the management of pelvic exenteration. Recent progress provided by the extralevator abdominoperineal resection technique and perforator flap concepts have changed our conception of reconstruction leading to the different technical options highlighted in this review.

The current abdominoperineal resection: oncological problems and surgical modifications for low rectal cancer.

Abdominoperineal resection is the one of the oldest surgical procedures for rectal cancer. Outcome after abdominoperineal resection for rectal carcinoma is not as good as anterior resection as the risk of local recurrence is higher and survival is poorer. During abdominoperineal resection, the rate of rectal perforation is high and the circumferential margin is often involved. Recently the concept of cylindrical abdominoperineal resection has been reintroduced. It allows a large excision and the initial results are encouraging. The purpose of this article was to analyse the oncological results of abdominoperineal resection and to develop the potential technical modifications of the procedure.

Perforator flaps: a new option in perineal reconstruction.

Over the past few decades, methodological progress and better anatomical knowledge have reduced the morbidity of reconstructive surgery. Muscle-sparing flaps and perforator flaps provide the surgeon with additional options for reconstruction. Based on a review of the local flaps used for perineal reconstruction, this article describes these new solutions and presents a decision tree (based on whether abdominal incision is required or not). If laparotomy is required, abdominal flaps should be preferred. If surgical excision is performed with the patient in the prone position, then gluteal and pudendal donor sites are recommended.
