Diagnostic yield of esophagogastroduodenoscopy in France.

Background And Study Aims: Large scale data on esophagogastroduodenoscopy (EGD) in Western countries are scarce. We conducted a prospective study on the diagnostic yield of upper gastrointestinal endoscopy in France.

Patients And Methods: An online questionnaire was sent to all French gastroenterologists practicing endoscopy.

Long-term follow-up after endoscopic resection for superficial esophageal squamous cell carcinoma: a multicenter Western study.

Background: Endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) are the first-line treatments for superficial esophageal squamous cell carcinoma (SCC). This study aimed to compare long-term clinical outcome and oncological clearance between EMR and ESD for the treatment of superficial esophageal SCC.

Methods: We conducted a retrospective multicenter study in five French tertiary care hospitals.

Efficacy of double-balloon enteroscopy for small-bowel polypectomy: clinical and economic evaluation.

Background: We evaluated first the feasibility of endoscopic small-bowel polypectomy and second, the economic aspects, by comparing the cost of endoscopic and surgical polyp resection.

Methods: A prospective, observational, multicenter study included 494 patients with positive capsule endoscopy (CE) before double-balloon enteroscopy (DBE). We selected only CE with at least one polyp.

Endoscopic papillectomy for early ampullary tumors: long-term results from a large multicenter prospective study.

Background And Study Aims: Endoscopic papillectomy of early tumors of the ampulla of Vater is an alternative to surgery. This large prospective multicenter study was aimed at evaluating the long-term results of endoscopic papillectomy.

Patients And Methods: Between September 2003 and January 2006, 10 centers included all patients referred for endoscopic papillectomy and meeting the inclusion criteria: biopsies showing at least adenoma, a uT1N0 lesion without intraductal involvement at endoscopic ultrasound (EUS), and no previous treatment.

Factors associated with adenoma detection rate and diagnosis of polyps and colorectal cancer during colonoscopy in France: results of a prospective, nationwide survey.

Introduction: Colonoscopy can prevent deaths due to colorectal cancer (CRC) through early diagnosis or resection of colonic adenomas. We conducted a prospective, nationwide study on colonoscopy practice in France.

Methods: An online questionnaire was administered to 2,600 French gastroenterologists.

Small bowel polypectomy by double balloon enteroscopy: Correlation with prior capsule endoscopy.

Aim: To investigate the feasibility of small bowel polypectomy using double balloon enteroscopy and to evaluate the correlation with capsule endoscopy (CE).

Methods: This is a retrospective review of a single tertiary hospital. Twenty-five patients treated by enteroscopy for small bowel polyps diagnosed by CE or other imaging techniques were included.

Multicenter comparison of double-balloon enteroscopy and spiral enteroscopy.

Background And Aim: Spiral enteroscopy is a novel technique for small bowel exploration. The aim of this study is to compare double-balloon and spiral enteroscopy in patients with suspected small bowel lesions.

Methods: Patients with suspected small bowel lesion diagnosed by capsule endoscopy were prospectively included between September 2009 and December 2010 in five tertiary-care academic medical centers.

Fully covered self-expanding metal stents for benign colonic strictures.

Background And Study Aims: Uncovered self-expanding metal stents offer effective relief for colonic obstruction. The aim of this study was to determine the effectiveness of fully covered self-expanding metal stents (FCSEMSs) in the treatment of benign colonic strictures.

Patients And Methods: All patients presenting with a symptomatic benign colonic stricture (occlusion or subocclusion) during a 6-year study period were treated with FCSEMSs.

The effect of inactivated Lactobacillus LB fermented culture medium on symptom severity: observational investigation in 297 patients with diarrhea-predominant irritable bowel syndrome.

Introduction: Little is known about the intensity of symptoms of diarrhea-predominant IBS (IBS-D) or the consequences of the disease on patients' health-related quality of life (HRQOL). This observational investigation assessed the symptoms (abdominal pain, bloating, number of stools per day, and stool consistency), impact on HRQOL, and consequence on anal continence in 297 patients with IBS-D before and after 1 month of probiotic treatment with Lacteol (inactivated Lactobacillus LB plus fermented culture medium).

Methods: Functional assessment using a standardized visual analogue scale in order to quantify abdominal pain, bloating, and quality of life before and after 1 month of treatment with 2 capsules/day of Lacteol.

Long-term outcome of patients treated with double balloon enteroscopy for small bowel vascular lesions.

Objectives: Early rebleeding rate after endoscopic therapy with double balloon enteroscopy (DBE) of hemorrhagic small bowel vascular lesions (SBVL) varies between 10 and 50%. In recent reports, long-term follow-up of patients have been described but rebleeding risk factors are still not well established. The aim of the current study was to identify long-term treatment success rate and rebleeding risk factors after DBE therapy in a large cohort.

A national survey of endoscopic mucosal resection for superficial gastrointestinal neoplasia.

Background And Study Aim: Studies on endoscopic mucosal resection (EMR) are mostly based on data from centers with high expertise. We report the average EMR results in a national survey of consecutive patients in France.

Methods: A 1-year survey was carried out to record immediate outcome data of all EMRs performed, regardless of lesion size or gastrointestinal location.

Endoscopic management of a large choledochocele associated with choledocholithiasis.

Choledochocele or type III choledochal cyst is a very rare lesion, defined as a cystic dilatation of the distal common bile duct protruding into the duodenal lumen. Abdominal pain, biliary disorders, and acute pancreatitis are frequently observed but malignant degeneration is rare. A 70-year-old man had a history of epigastralgia associated with abnormal liver function tests suggesting gallstones.

Similar performance but higher cholecystitis rate with covered biliary stents: results from a prospective multicenter evaluation.

Background And Study Aims: Endoscopic biliary stenting is now a well-established treatment method in patients with unresectable malignant biliary obstruction. Despite advances with metal stents, the problem of stent occlusion has not yet been resolved. Covered metal stents could reduce the occlusion rate by preventing tumor ingrowth, but have not been well evaluated.

Assessment of patient satisfaction with endoscopy using an interactive voice response system.

Aim: The aim of this study was to determine the feasibility of patient's satisfaction assessment after endoscopy using an interactive voice response (IVR) system.

Methods: A specific IVR system was developed for this study and proposed to patients by 161 private gastroenterologists after an endoscopic procedure. No reminder was used for the patients not calling spontaneously the IVR.

High resolution colonoscopy with chromoscopy versus standard colonoscopy for the detection of colonic neoplasia: a randomized study.

Background & Aims: High-resolution colonoscopy with chromoscopy (HRC) is a technique designed to improve the detection of colonic neoplasias. We prospectively compared standard colonoscopy (SC) and HRC in a randomized multicenter trial.

Methods: Patients (n = 203; age, 58 +/- 10 years; sex ratio, 1) were recruited according to the following criteria: (1) a history of either familial or personal colonic neoplasia or (2) alarm symptoms after the age of 60 years.

A prospective national study on colonoscopy and sigmoidoscopy in 2000 in France.

Aim: The aim of this study was to evaluate the practice of colonoscopy and sigmoidoscopy in France in 2000.

Methods: A prospective study was conducted in November 2000 using questionnaires sent to all gastroenterologists practicing in France (N=2858) who were asked to reply to items concerning colonoscopies and sigmoidoscopies performed on two workdays chosen in advance. The response rate was 32.
