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).

French multicentre prospective evaluation of radiofrequency ablation in the management of haemorrhoidal disease.

PURPOSE: The aim of this study was to evaluate the efficacy and safety of radiofrequency ablation (RFA) in the management of haemorrhoidal disease with 1 year's follow-up. METHOD: This prospective multicentre study assessed RFA (Rafaelo©) in outpatients with grade II-III haemorrhoids. RFA was performed in the operating room under locoregional or general anaesthesia. Primary endpoint was the evolution of a quality-of-life score adapted to the haemorrhoid pathology (HEMO-FISS-QoL) 3 months after surgery. Secondary endpoints were evolution of symptoms (prolapsus, bleeding, pain, itching, anal discomfort), complications, postoperative pain and medical leave. RESULTS: A total of 129 patients (69% men, median age 49 years) were operated on in 16 French centres. Median HEMO-FISS-QoL score dropped significantly from 17.4/100 to 0/100 (p < 0.0001) at 3 months. At 3 months, the rate of patients reporting bleeding (21% vs. 84%, p < 0.001), prolapse (34% vs. 91.3%, p < 0.001) and anal discomfort (0/10 vs. 5/10, p < 0.0001) decreased significantly. Median medical leave was 4 days [1-14]. Postoperative pain was 4/10, 1/10, 0/10 and 0/10 at weeks 1, 2, 3 and 4. Seven patients (5.4%) were reoperated on by haemorrhoidectomy for relapse, and three for complications. Reported complications were haemorrhage (3), dysuria (3), abscess (2), anal fissure (1), external haemorrhoidal thrombosis (10), pain requiring morphine (11). Degree of satisfaction was high (+ 5 at 3 months on a - 5/+ 5 scale). CONCLUSION: RFA is associated with an improvement in quality of life and symptoms with a good safety profile. As expected for minimally invasive surgery, postoperative pain is minor with short medical leave. CLINICAL TRIAL REGISTRATION AND DATE: Clinical trial NCT04229784 (18/01/2020).

Does stoma modify compliance with enhanced recovery after surgery programs? Results of a cohort study.

PURPOSE: Few studies have focused on enhanced recovery programs (ERPs) in patients who have received a stoma after colorectal surgery. The objective of the study was to compare ERP compliant patients who have not received a stoma, those who received a colostomy, and those who received an ileostomy. METHODS: This study used data that had been prospectively collected as part of the ERP audit performed through the Groupe francophone de Réhabilitation Améliorée après Chirurgie [Francophone Group for Enhanced Recovery after Surgery] over a 4-year period. All patients who had undergone colorectal surgery were included and separated into three groups (no stoma, ileostomy, and colostomy). The primary outcome was ERP compliance, calculated through the use of 16 tracer items. RESULTS: Of the 422 recruited patients, 317 had not received a stoma (75.12%), 59 had an ileostomy (13.98%), and 46 had a colostomy (10.90%). ERP compliance was 73% in the non-stoma group, 66.6% in the ileostomy group, and 66% in the colostomy group (p < 0.001). Multivariate analysis showed that patients from the ileostomy group had a higher risk of bowel preparation [OR = 9.1; 95% CI = 1.16-71.65] and of maintaining their urinary catheter [OR = 0.3; 95% CI = 0.14-0.81] than the group which did not receive a stoma. Patients from the colostomy group required significantly more drainage than those in the non-stoma group (OR = 4.3; 95% CI = 1.33-14.02). CONCLUSION: ERP is feasible in colorectal surgery in the context of stomas, but in case of ileostomy protecting a rectal surgery, the audit system must be adapted to the protocols in use in the departments.

Surgical management of adhesive small bowel obstruction: Is it still mandatory to wait? - An update.

Small bowel obstruction syndromes (SBO) represent one of the main causes of emergency admission for surgical abdominal pain. The 2018 Bologna Guidelines (Ten Broek et al. 2018) recommend non-operative management at the outset if there are no signs of severity; surgery is proposed after 72h for the 20-30% of patients who fail medical management. However, these recommendations were based on old studies published at a time when laparoscopic surgery was not commonplace and when diagnostic capabilities (particularly for establishing etiology) were less developed than they are today. Additionally, the advent and development of laparoscopy and enhanced rehabilitation after surgery have led to a decrease in surgical morbidity. These guidelines are therefore now debated and several recent publications have encouraged urgent or semi-urgent surgical management for patients presenting for SBO in order to reduce morbidity, mortality, duration of hospitalization and costs, and to improve the feasibility of therapeutic laparoscopy. Prompt surgical management could also reduce the risk of recurrent small bowel obstructions. This model for early surgical management probably cannot be applied to all patients. It therefore seems important to select those patients at risk for failure of medical treatment and to identify those in whom the probability of successful laparoscopy is high. New radiological tools should allow better selection in the future. At the present time, the indications for early surgery "within 24h" should be emphasized.

Management of obstetrical injuries to the anal sphincter: A survey of French current practice and perceptions according to the specialties.

AIM OF THE STUDY: To conduct a survey of current practice in the management of obstetrical anal sphincter injuries (OASI) and to compare short, medium and long-term practices according to the specialty of the surgeon. PATIENTS AND METHODS: A 50-item questionnaire was addressed by mail to various specialists via the national learned societies. The questionnaire was addressed only to practitioners who currently managed OASI in their practice. RESULTS: Of the 135 healthcare professionals who responded, 57 were sub-specialists in ano-rectal surgery (42.2%) and 78 were obstetrical or gynecological specialists (OB-GYN) (57.8%). Management in the acute period after OASI was similar among the specialties and 50% of the practitioners did not perform suture repair of the internal sphincter. Furthermore, few gynecological specialists recommended systematic consultation with an ano-rectal specialist during acute management. In the medium term, ano-rectal specialists were more likely to explore gastro-intestinal symptoms, either clinically or through para-clinical studies. However, these studies did not systematically lead to interventional management in the absence of consensus, particularly for medium-term sphincter repair. In addition, 25% of practitioners recommended that patients undergo systematic delivery by caesarean section for further pregnancies after OASI. In the long term (>12 months), there were substantial differences in management of OASI not only between specialties but also within the same specialty. CONCLUSION: The various specialists should coordinate to propose multidisciplinary recommendations on the management of OASI.

Management and consequences of obstetrical anal sphincter injuries: Review.

Obstetrical anal sphincter injuries (OASI), formerly referred to as "complete" or "incomplete" perineal tears, are a frequent complication of childbirth. They can lead to intestinal consequences (anal incontinence, ano-genital fistula) or sexual consequences (dyspareunia, genital pain). The complexity of management of OASI lies in the multi-factorial nature of these consequences but also in the frequently lengthy interval before their appearance, often long after childbirth. Indeed, while 2.4% of women in childbirth develop OASI, up to 61% of them will present with anal incontinence15 to 25 years after childbirth. Immediate or delayed repair of the sphincter and perineum within a few hours of injury is therefore the rule, but there is no consensus on longer-term management. The patient must be educated on preventive actions (avoidance of pushing or straining, regularization of stool transit, muscle strengthening, etc.). Early detection of anal incontinence leads to prompt management, which is more effective. This review aims to synthesize the information necessary to provide clear and up-to-date patient information on OASI (risk factors and prevalence), the management of OASI, and the management of eventual complications in the setting of dedicated specialty consultations. Dedicated "post-OASI" consultations by a specialist in ano-perineal pathologies could therefore become a first step in the development of care for women, particularly by removing the "shameful" nature of the symptoms.

Gastrointestinal motility has more of an impact on postoperative recovery than you might expect.

PURPOSE: While patient's reported autonomy (PRA) may help the physician to adapt the day of discharge, the link between postoperative ileus and length of stay and PRA is not known. The aim of this study was to evaluate the evolution of the PRA score during the postoperative period and to determine the factors possibly influencing such an evolution. METHODS: This retrospective study on a prospective database took place in a single centre over 14 months. PRA was defined by the by using part I of the Groningen Activity Restriction Scale known as activity of daily life [from 9 (best) to 45 (worst)]. RESULTS: Among the 101 patients operated on for elective or emergent colorectal surgery, 80% of the patients had recovered their preoperative PRA (±5 points) before discharge and maintained their PRA during the 2 days preceding discharge. While PRA was significantly decreased by surgery (P<0.0001), each postoperative day allowed for its progressive recovery. Interestingly, the day of recovery of GI transit was associated with a significant increase of PRA (-6.96 points, P<0.0001). Despite high variability of baseline autonomy level, patients presented very similar recovery processes, which were represented by very low slope variability in the linear mixed model. Laparoscopy reduced the decrease of postoperative PRA (P=0.03) while ASA score>2 increased PRA (P=0.03). Age, emergency surgery and the occurrence of postoperative morbidity did not affect postoperative autonomy. Finally, enhanced recovery programs (ERP) tended to improve postoperative autonomy recovery (P=0.09). CONCLUSION: PRA may be used as a means of optimising a patient's day of discharge following colorectal surgery.

Urine drainage management in colorectal surgery.

INTRODUCTION: Enhanced recovery programs (ERP) is aimed at reducing a patient's surgical stress response, specifically by reducing the duration of catheterization. In cases of colorectal surgery, there is pronounced heterogeneity in urinary catheterization, which is largely explained by fear of acute urinary retention (AUR). OBJECTIVE: The objective of the work is to report on the current literature on postoperative urinary catheterization following colorectal surgery, particularly with regard to the risk of AUR, and thereby contribute to the standardization of perioperative practices. RESULTS: In colon surgery without preoperative urinary disorders, catheterization must not exceed 24h. In rectal surgery, catheter removal starting on postoperative D2 seems reasonable in the absence of AUR risk factor (RF). Male sex, past history of lower urinary tract obstruction, abdomino-perineal amputation (APA) and low rectal anastomosis are AUR risk factors that must be taken into account when deciding to withdraw the urinary catheter. While the role of a suprapubic catheter is not clearly defined, it may be of use following APA. The epidural catheter is another AUR risk factor, but it seems possible to withdraw the urinary catheter on postoperative D1, before the epidural catheter, provided that the other risk factors have been taken into full account. Lastly, up until now no satisfactorily conducted study has assessed the prophylactic value of systematic perioperative alpha-blocker treatment in colorectal surgery.

Incidence and Risk Factors for Severity of Postoperative Ileus After Colorectal Surgery: A Prospective Registry Data Analysis.

BACKGROUND: Defining severe postoperative ileus in terms of consequences could help physicians standardize the management of this condition. The recently described classification based on consequences requires further investigation. The aim of this study was to obtain a snapshot of postoperative ileus in patients undergoing colorectal surgery within enhanced recovery programs and to identify factors associated with non-severe and severe postoperative ileus. METHODS: This prospective registry data analysis was conducted in 40 centers in five different countries. A total of 786 patients scheduled for colorectal surgery within enhanced recovery programs were included. The primary endpoint was the incidence rate of postoperative ileus as defined by Vather et al. RESULTS: A total of 121 patients experienced postoperative ileus (15.4%). Non-severe POI occurred in 48 patients (6.1%), and severe postoperative ileus occurred in 73 patients (9.3%). In multivariate analysis, the male gender and intra-abdominal complications were associated with severe postoperative ileus: odd ratio (OR) = 2.03 [95% confidence interval (CI) 1.14-3.59], p = 0.01 and OR = 3.60 [95% CI 1.75-7.40], p < 0.0001, respectively. Conversely, open laparotomy and urinary retention were associated with non-severe POI: OR = 3.03 [95% CI 1.37-6.72], p = 0.006 and OR = 2.70 [95% CI 0.89-8.23], p = 0.08, respectively. CONCLUSIONS: Postoperative ileus occurred in 15% of patients after colorectal surgery within enhanced recovery programs. For 60% of patients, this was considered severe. The physiopathology of these two entities could be different, severe POI being linked to intraabdominal complication, while non-severe POI being linked with risk factors for "primary" POI. The physician should pay attention to male patients having POI after colorectal surgery and look for features evocating intraabdominal complications.

Surgical management of obstructive left colon cancer at a national level: Results of a multicentre study of the French Surgical Association in 1500 patients.

PURPOSE: Surgical management of obstructive left colon cancer (OLCC) is controversial. The objective is to report on postoperative and oncological outcomes of the different surgical options in patients operated on for OLCC. METHODS: From 2000-2015, 1500 patients were treated for OLCC in centers members of the French Surgical Association. Colonic stent (n=271), supportive care (n=5), palliative derivation (n=4) were excluded. Among 1220 remaining patients, 456 had primary diverting colostomy (PDC), 329 a segmental colectomy (SC), 246 a Hartmann's procedure (HP) and 189 a subtotal colectomy (STC) as first-stage surgery. Perioperative data and oncological outcomes were compared retrospectively. RESULTS: There was no difference between the 4 groups regarding gender, age, BMI and comorbidities. Postoperative mortality and morbidity were 4-27% (PDC), 6-47% (SC), 9-55% (HP), 13-60% (STC), respectively (P=0.005). Among the 431 living patients after PDC, 321 (70%) patients had their primary tumour removed. Cumulative mortality and morbidity favoured PDC (7-39%) and SC (6-40%) compared to HP (1-47%) and STC (13-50%) (P=0.04). At the end of follow-up definitive stoma rates were 39% (HP), 24% (PDC), 10% (SC), and 8% (STC) (P<0.0001). Five-year overall and disease-free survival was: SC (67-55%), PDC (54-48%), HP (54-37%) and STC (48-49%). After multivariate analysis, SC and PDC were associated with better prognosis compared to HP and STC. CONCLUSION: In OLCC, SC and PDC are the two preferred options in patients with good medical conditions. For patients with severe comorbidities PDC should be recommended, reserving HP and STC for patients with colonic ischaemia or perforation complicating malignant obstruction.

Thirty-day mortality after emergency surgery for obstructing colon cancer: survey and dedicated score from the French Surgical Association.

AIM: The aim was to define risk factors for postoperative mortality in patients undergoing emergency surgery for obstructing colon cancer (OCC) and to propose a dedicated score. METHOD: From 2000 to 2015, 2325 patients were treated for OCC in French surgical centres by members of the French National Surgical Association. A multivariate analysis was performed for variables with P value ≤ 0.20 in the univariate analysis for 30-day mortality. Predictive performance was assessed by the area under the receiver operating characteristic curve. RESULTS: A total of 1983 patients were included. Thirty-day postoperative mortality was 7%. Multivariate analysis found five significant independent risk factors: age ≥ 75 (P = 0.013), American Society of Anesthesiologists (ASA) score ≥ III (P = 0.027), pulmonary comorbidity (P = 0.0002), right-sided cancer (P = 0.047) and haemodynamic failure (P < 0.0001). The odds ratio for risk of postoperative death was 3.42 with one factor, 5.80 with two factors, 15.73 with three factors, 29.23 with four factors and 77.25 with five factors. The discriminating capacity in predicting 30-day postoperative mortality was 0.80. CONCLUSION: Thirty-day postoperative mortality after emergency surgery for OCC is correlated with age, ASA score, pulmonary comorbidity, site of tumour and haemodynamic failure, with a specific score ranging from 0 to 5.

Long-term outcome and management of right colonic diverticulitis in western countries: Multicentric Retrospective Study.

AIM OF THE STUDY: Right colonic Diverticulitis (RD) is rare in Europe; few studies have focused on it and its management is not standardised. The aim of this study was to analyse the clinical presentation (complicated, uncomplicated), acute phase management and long-term outcome of RD in western countries. PATIENTS AND METHODS: From 2003 to 2017, 93 consecutive patients who presented with RD were retrospectively included at 11 French Hospital Centres. RESULTS: The study population consisted of two groups: Uncomplicated Right Diverticulitis (URD) group (63.5%, (n=59)) and Complicated Right Diverticulitis (CRD) group (36.5%, [n=34]). 84.7% (n=50/59) of URD were treated conservatively. 41.2% (n=14/34) of patients with CRD had emergency surgery (mostly laparotomy) for Hinchey III peritonitis, clinical intolerance or hemodynamic instability. Altogether 5.2% (n=2/34) patients with CRD had surgery after a cooling off period (initially abscess). The overall rate of severe postoperative complications was low (8%). Recurrence rate was low and comparable in both groups: 6.8% (n=4/59) for URD and 8.8% (n=3/34) for CRD, all recurrences occurred in the same locations with an uncomplicated form, 42.9% (n=3/7) of them had elective laparoscopic surgery and the rest were conservatively treated. Median follow up was 33.2 months. CONCLUSION: Conservative treatment can be proposed safely and efficiently for URD and for selected patients with CRD. Surgery should be reserved for unstable patients or patients with severe forms of complicated diverticulitis in emergency.

The Predictive Value of Pulse Wave Velocity for Anastomotic Leakage After Colorectal Surgery.

BACKGROUND: Arterial perfusion defects are a risk factor for anastomotic leakage (AL) following colorectal surgery. Measuring arterial stiffness using pulse wave velocity (PWV) is known to reflect the performance of the arterial network. The objective of this study was to assess the predictive value of PWV for AL after colorectal surgery. METHODS: A prospective monocentric study was conducted on all consecutive patients who underwent colorectal surgery scheduled between March 1, 2016 and May 1, 2017. Patients were divided into two groups according to the PWV which was measured preoperatively using the pOpmètre® device: PWV+ (PWV > 10 m/s) and PWV- (PWV ≤ 10 m/s). We then compared the PWV+ and PWV- groups. The primary endpoint was the AL rate. RESULTS: A total of 96 patients were studied, including 60 in the PWV- group and 36 in the PWV+ group. Patients in the PWV+ group were more at risk of presenting with AL than those in the PWV- group (6.25 vs 0%) (p = 0.002). There was no difference in immediate postoperative complications between the two groups apart from the length of hospital stay. PWV predicted the appearance of AL with a sensitivity of and a negative predictive value of 100%. CONCLUSION: Measuring PWV could be a used as a predictive examination in the early detection of AL after colorectal surgery.

Short-Term Outcomes of Colorectal Resection for Cancer in Elderly in the Era of Enhanced Recovery.

BACKGROUND AND AIMS: Early rehabilitation protocols should be assessed in elderly. We aimed to study the outcomes of colorectal surgery and the observance of the modalities of an early rehabilitation protocol in patients over 80 years. MATERIAL AND METHODS: All consecutive patients who underwent surgery for colorectal cancer in our center over a 19-month period were included. All of these patients were managed using the same early rehabilitation protocol. Patients older than 80 were compared to younger patients. RESULTS: A total of 173 patients were included and 36 were ≥80 years (20.8%). Patients aged ≥80 years had a significantly higher ASA score and were operated on in emergency. In the peroperative period, patients aged ≥80 years were more likely to undergo laparotomy than patients <80 years in univariate analysis (p = 0.048), but in multivariate analysis, the choice for a laparoscopy was influenced by ASA score ≤2 (odds ratio = 3.55, 95% confidence interval = 1.67-7.58) and emergency surgery (odds ratio = 0.18, 95% confidence interval = 0.06-0.50). In the postoperative period, peristalsis stimulation and vascular catheter ablation were significantly better followed in Group 1 (p = 0.012 and 0.031). However, in multivariate analysis, age was not significantly associated with these parameters. Peristalsis stimulation was influenced by ASA score ≥2 (odds ratio = 4.27, 95% confidence interval = 1.18-15.37) and vascular catheter ablation was also influenced by ASA score ≤2 (odds ratio = 2.63, 95% confidence interval = 1.33-5.21). Emergency surgery had a strong trend to influence these parameters (p = 0.08). CONCLUSION: Although age or comorbidities may affect observance for certain modalities such as chewing gum use and vascular catheter ablation, an early rehabilitation protocol can be used after colorectal cancer surgery in patients ≥80 years old, where it would improve functional results and postoperative outcomes.

Risk factors for symptomatic esophageal stricture after caustic ingestion-a retrospective cohort study.

Esophageal stricture is a major secondary complication of ingesting caustic agents. We examined our experiences with caustic injuries with a view to finding clinical and biological risk factors of esophageal strictures secondary to caustic ingestion. Records were retrieved for 58 adults admitted consecutively to our intensive care unit for caustic ingestion. Fifty cases were managed conservatively and therefore retained for analyses. Patients were grouped according to whether they developed strictures or not during the follow-up period. Mucosal damage was assessed by emergency endoscopy. Eleven patients (22%) developed a stricture. At referral, dysphagia, epigastric pain, and hematemesis were associated with secondary stricture (respectively P = 0.047, P = 0.008, P = 0.02). A high Zargar endoscopic grade (above IIa; P = 0.02), the ingestion of strong acids or alkalis (P = 0.006), hyperleukocytosis (P = 0.02), and a low prothrombin ratio (P = 0.002) were associated with a higher risk of developing a stricture. The median delay of stricture diagnosis was 12 (8;16) days after ingestion, with extreme values from 4 to 26 days. Initial symptoms such as dysphagia or hematemesis, early endoscopy showing >IIa grade esophagitis, and certain laboratory results should draw the physician's attention to a high risk of esophageal stricture.

In-hospital clinical outcomes after upper gastrointestinal surgery: Data from an international observational study.

AIMS: Previous research suggests that patients undergoing upper gastrointestinal surgery are at high risk of poor postoperative outcomes. The aim of our study was to describe patient outcomes after elective upper gastrointestinal surgery at a global level. METHODS: Prospective analysis of data collected during an international seven-day cohort study of 474 hospitals in 27 countries. Patients undergoing elective upper gastrointestinal surgery were recruited. Outcome measures were in-hospital complications and mortality at 30-days. Results are presented as n(%) and odds ratios with 95% confidence intervals. RESULTS: 2139 patients were included, of whom 498 (23.2%) developed one or more postoperative complications, with 30 deaths (1.4%). Patients with complications had longer median hospital stay 11 (6-18) days vs. 5 (2-10) days. Infectious complications were most frequent, affecting 368 (17.2%) patients. 328 (15.3%) patients were admitted to critical care postoperatively, of whom 161 (49.1%) developed a complication with 14 deaths (4.3%). In a multivariable logistic regression model we identified age (OR 1.02 [1.01-1.03]), American Society of Anesthesiologists physical status III (OR 2.12 [1.44-3.16]) and IV (OR 3.23 [1.72-6.09]), surgery for cancer (OR 1.63 [1.27-2.11]), open procedure (OR 1.40 [1.10-1.78]), intermediate surgery (OR 1.75 [1.12-2.81]) and major surgery (OR 2.65 [1.72-4.23]) as independent risk factors for postoperative complications. Patients undergoing major surgery for upper gastrointestinal cancer experienced twice the rate of complications compared to those undergoing other procedures (224/578 patients [38.8%] versus 274/1561 patients [17.6%]). CONCLUSIONS: Complications and death are common after upper gastrointestinal surgery. Patients undergoing major surgery for cancer are at greatest risk.

Primary Surgery for Malignant Large Bowel Obstruction: Postoperative Nasogastric Tube Reinsertion is Not Mandatory.

BACKGROUND: Malignant large bowel obstructions frequently require emergency surgery. Compliance with enhanced recovery after surgery programmes is significantly reduced due to non-removal of the nasogastric tube in the postoperative period. The first aim of the present study was to research factors associated with the failure of immediate nasogastric tube removal in patients who had undergone emergency surgery for malignant large bowel obstruction. The second aim was to assess the morbidity linked to nasogastric tube reinsertion. METHODS: This retrospective and monocentric study included all consecutive patients admitted for acute malignant large bowel obstruction who underwent emergency surgery. Patients who were not primarily operated on were excluded (n = 178; 69.3%). The group of patients requiring nasogastric tube (NGT) reinsertion was compared with the group that did not require NGT reinsertion. RESULTS: Seventy-nine patients underwent emergency surgery, of which 18 (22.8%) required nasogastric tube reinsertion. There was no difference between the two groups with regard to (a) immediate nasogastric tube removal (p = 0.87) and (b) inclusion in an enhanced recovery programme (p = 0.75). However, preoperative small bowel dilatation was associated with a reduction in the need for NGT reinsertion (p = 0.04). A left-sided tumour was also associated with the need for NGT reinsertion in uni- (p = 0.034) and multivariate analysis (OR = 8; p < 0.05). Surgical access and procedure were not significantly associated with NGT reinsertion. The postoperative course influenced NGT reinsertion, which was significantly associated with postoperative ileus (OR = 4; p < 0.05) and postoperative morbidity (OR = 4; p < 0.05). Morbidity was not linked to nasogastric tube removal. CONCLUSION: Nasogastric tube reinsertion was not affected by immediate removal of the tube. Left-sided tumours and patients at risk of postoperative ileus should be managed with caution. Immediate nasogastric tube removal is not contraindicated in the case of large bowel obstruction because it is not associated with a higher risk of NGT reinsertion.

CT findings of complications after abdominal wall repair with prosthetic mesh.

Postoperative complications following prosthetic mesh repair are relatively rare and depend on the type and location of prosthetic mesh. They include abscess, hematoma, seroma, fistula, bowel obstruction, mesh retraction, granuloma and recurrent hernia. Computed tomography (CT) is the imaging examination of choice for the diagnosis of such complications. This pictorial review illustrates the CT presentation of the most and less common postoperative complications following prosthetic mesh repair of the abdominal wall.

Failure of Conservative Treatment of Acute Diverticulitis with Extradigestive Air.

BACKGROUND: Medical management for perforated diverticulitis without abscess or peritonitis (PDwAP) has a success rate of 40-70%. Identifying patients with a risk of medical treatment failure would improve outcomes. The aim of this study was to identify the risk factors for failure of medical treatment in patients admitted with PDwAP. METHODS: This multicenter retrospective observational study included all consecutive patients admitted for PDwAP and not surgically treated over a 7-year period. Peritonitis classified on the Hinchey scale was excluded. Potential clinical, biological and radiological risk factors for medical treatment failure were collected and compared between the group of patient with a failure of medical treatment (F) and the group in which treatment did not fail. Data were collected at referral. RESULTS: Ninety-one patients were included, and 29 had a failure of treatment (31.9%). The median heart rate was different between the two groups (p < 0.001), at approximately 100/min in the F group. A blood level of C-reactive protein (CRP) ≥150 mg/mL was associated with a higher rate of failure (p = 0.021), but it was not confirmed in multivariate analysis. Pneumoperitoneum ≥5 mm and intraperitoneal liquid located in the pouch of Douglas were more likely to be present in the F group (respectively, p = 0.001 and p < 0.001). A multivariate analysis showed independent risk factors as being the highest pneumoperitoneum diameter >5 mm (OR 5.193; p = 0.015) and peritoneal fluid location in the pouch of Douglas (OR 4.103; p = 0.036). CONCLUSION: The severity of sepsis (tachycardia and CRP ≥150 mg/mL) and of imaging signs (pneumoperitoneum ≥5 mm and peritoneal fluid in the pouch of Douglas) were risk factors for medical treatment failure of PDwAP requiring special supervision so as not to lose time in undertaking surgical management.
