Factors associated with Clostridium difficile infection: A nested case-control study in a three year prospective cohort.

Background: Clostridium difficile infection (CDI) is a serious medical condition that is associated with substantial morbidity and mortality. Identification of risk factors associated with CDI and prompt recognition of patients at risk is key to successfully preventing CDI.

Methods: A 3-year prospective, observational, cohort study was conducted in a French university hospital and a nested case-control study was performed to identify risk factors for CDI.

Impact of sleeve gastrectomy volumes on weight loss results: a prospective study.

Background: Causes of weight loss failure after sleeve gastrectomy (SG) are still controversial. The impact of the size of the sleeve continues to be debated.

Objective: The aim of our study was to determine the impact of sleeve volumes assessed at 3 months using gastric computed tomography (CT) on weight loss at 18 months.

Dilatation of Sleeve Gastrectomy: Myth or Reality?

Objectives: The success of longitudinal sleeve gastrectomy (LSG) is perceived as being potentially limited by dilatation of the remaining gastric tube during the follow-up. The aim of this prospective study was to determine the incidence and the characteristics of sleeve dilatation during the first post-operative year.

Materials And Methods: Gastric volumetry using 3D gastric computed tomography with gas expansion was performed in 54 successive subjects who underwent an LSG for morbid obesity at 3 and 12 months following surgery.

Bariatric Surgery Outcomes in Sarcopenic Obesity.

Background: Sarcopenic obesity is the combination of low muscle mass and strength with increased fat mass. This condition is associated with negative health outcomes. We hypothesized that sarcopenia could be a pejorative factor on surgical weight loss.

Medico-legal analysis of legal complaints in bariatric surgery: a 15-year retrospective study.

Background: Bariatric surgery for severe obesity has become an effective and accepted treatment for sustained weight loss.

Objectives: The aim of our study was to analyze the complications and issues raised by the experts on which jury or judges' decisions were made for the different types of bariatric surgery.

Setting: University Hospital, France.

Impact of Pregnancy on Weight Loss and Quality of Life Following Gastric Banding.

Background-objectives: Despite pregnancy being a common event following laparoscopic adjustable gastric banding (LAGB), there is little comprehensive data regarding its effect on postoperative outcome. The aim of this study was to assess the impact of pregnancy on the postoperative changes in quality of life (QOL) and total weight loss 3 years after LAGB.

Setting: Multi-institutional, France.

Should we wait for metabolic complications before operating on obese patients? Gastric bypass outcomes in metabolically healthy obese individuals.

Background: A subgroup of obese patients without metabolic disorders has been identified and defined as metabolically healthy but morbidly obese (MHMO).

Objectives: To compare Roux-en-Y gastric bypass (RYGB) outcomes between MHMO and metabolically unhealthy morbidly obese (MUMO) patients to assess whether the obesity phenotype could affect the results.

Setting: A university-affiliated tertiary care center.

Relevance of Roux-en-Y gastric bypass volumetry using 3-dimensional gastric computed tomography with gas to predict weight loss at 1 year.

Background: Causes of Roux-en-Y gastric bypass (RYGB) failures are still controversial. Literature data suggest that gastric pouch or gastrojejunal anastomosis distentions over time could be a key factor. Making the hypothesis that progressive distention of RYGB volumes is 1 of the main factors of weight loss failure, the aim of our study was to evaluate bypass volumes changes using repeated 3-dimensional gastric computed tomography with gas and the possible negative correlation with weight loss results at 1 year.

Radiofrequency ablation device assisted liver resection for hepatocellular carcinoma.

Unlabelled: The present study aim was to evaluate radiofrequency (RF)-assisted liver resection for hepatocellular carcinoma (HCC).

Patients And Methods: 35 consecutive patients were enrolled in this study. A Habib®4X RF ablation device (RFAD) was used for liver resection.

Gastric bypass for obesity in the elderly: is it as appropriate as for young and middle-aged populations?

Background: Obesity prevalence increases in elderly population. Bariatric surgery has been underused in patients over 60 because of fears of complications and lower weight loss. We postulated worse outcomes in the elderly in comparison to young and middle-aged population 1 year after gastric bypass.

Greater weight loss with the omega loop bypass compared to the Roux-en-Y gastric bypass: a comparative study.

Background: Despite similar initial results on weight loss and metabolic control, with a better feasibility than the Roux-en-Y gastric bypass (RYGBP), the omega loop bypass (OLB) remains controversial. The aim of this study was to compare the short-term outcomes of the laparoscopic OLB versus the RYGBP in terms of weight loss, metabolic control, and safety.

Methods: Two groups of consecutive patients who underwent laparoscopic gastric bypass surgery were selected: 20 OLB patients and 61 RYGBP patients.

Prospective longitudinal assessment of change in health-related quality of life after adjustable gastric banding.

Background: Gastric banding remains a common procedure worldwide. Improving health-related quality of life (HRQOL) has become a major goal in the treatment of patients with chronic diseases, yet there are few comprehensive data regarding the effect of gastric banding on HRQOL. The aim of this study was to evaluate the impact of laparoscopic gastric banding on HRQOL with particular regard to change over time.

Predictive factors of type 2 diabetes remission 1 year after bariatric surgery: impact of surgical techniques.

Type 2 diabetes (T2D) remission after bariatric procedures has been highlighted in many retrospective and some recent prospective studies. However, in the most recent prospective study, more than 50 % of patients did not reach T2D remission at 1 year. Our aim was to identify baseline positive predictors for T2D remission at 1 year after bariatric surgery and to build a preoperative predictive score.

Preoperative fat-free mass: a predictive factor of weight loss after gastric bypass.

Weight loss failure occurs in 8% to 40% of patients after gastric bypass (GBP). The aim of our study was to analyse the predictive factors of weight loss at 1 year so as to select the best candidates for this surgery and reduce the failures. We included 73 patients treated by laparoscopic GBP.

Achalasia-like disorder after laparoscopic adjustable gastric banding: a reversible side effect?

Literature data concerning the effect of laparoscopic adjustable gastric banding (LAGB) on esophageal motility are conflicting. Achalasia-like disorder involving the absence of esophageal peristalsis and impaired esophago-gastric junction (EGJ) is probably under-estimated and can result in failure and band removal. The aim of our study was to focus on cases of achalasia-like disorder and study its evolution after band deflating or removal.

Transthoracic approach for liver tumors.

Abdominal approach is commonly used for resection of liver tumors. However, in rare cases, transthoracic approach may be a valuable option for management of lesions located in the hepatic dome or involving the cavo-hepatic junction for very selected patients. This approach can be an open procedure (thoracotomomy), a video-assisted minimally invasive technique (thoracoscopy), or a strictly percutaneously treatment (CT-guided radiofrequency ablation).

Prospective, multicenter, 3-year trial of laparoscopic adjustable gastric banding with the MIDBAND™.

Background: Although laparoscopic adjustable gastric banding (LAGB) is a popular metabolic/bariatric procedure, few prospective studies have assessed its outcomes. This study aimed to prospectively assess LAGB safety and effectiveness outcomes using the MIDBAND™ (MID, Dardilly, France).

Methods: Between May 2005 and September 2006, 262 morbidly obese patients underwent primary gastric banding with pars flaccida technique in 13 French medical centers.

High resolution esophageal manometry evaluation in symptomatic patients after gastric banding for morbid obesity.

Background: Dysphagia and vomiting are frequent after laparoscopic gastric banding (LAGB). These symptoms could be secondary to esophageal motility disorders. Our aim was to assess esophageal motility and clearance in symptomatic LAGB patients using high resolution manometry (HRM).

3D gastric computed tomography as a new imaging in patients with failure or complication after bariatric surgery.

The number of bariatric operations performed each year is increasing. As a result, a rising number of patients in possible need for revisional surgery are referred to bariatric surgeons. But the standard methods of evaluation are often insufficient, and the best strategy remains difficult to choose.

Safety and long-term outcome of a new concept for surgical adhesion-reduction strategies (Prevadh): a prospective, multicenter study.

Background/aims: No agent has been consistently effective in preventing formation of peritoneal adhesions and postoperative bowel obstruction after abdominal surgery. The aim of this prospective multicenter study was to assess clinical safety and efficiency of a new adhesion-reduction barrier

Methodology: Between September 2000 and April 2001, Prevadh was used in 78 patients. Operative procedures included 25 hepatic resections, 7 cholecystectomies, 32 colonic resections, 7 protectomies, 3 colostomy or recovery of continuity, 1 gynaecologic surgery and 3 others.

[Functional outcome and quality of life after pancreaticoduodenectomy].

Aim Of Study: Pancreaticoduodenectomy is a major surgical procedure whose physiological effects may weigh heavily on quality of life. The goal of this retrospective unicentric pilot study was to assess the the functional outcome after pancreaticoduodenectomy and its effect on the patient's quality of life.

Patients And Method: Thirty patients free from tumor recurrence more than one year after pancreaticoduodenectomy responded to the GIQLI questionnaire (Gastro Intestinal Quality of Life Index) and to a specific questionnaire evaluating long-term functional outcome.

[Pancreaticoduodenectomy for cancer of the head of the pancreas].

Many modifications of the original technique have been proposed to try to improve the results of the pancreaticoduodenectomy described by Whipple. To evaluate these modifications, we have reviewed randomized controlled trials, meta-analyses, and well-conducted retrospective series. Neither total pancreatectomy nor extended lymph node dissections have shown an improve of survival in retrospective studies.
