Abstract
INTRODUCTION Self-expanding metal stents (SEMS) are commonly used in the palliation of dysphagia in patients with inoperable esophageal carcinoma. However, they predispose to gastroesophageal reflux when deployed across the gastroesophageal junction. The aims of this study were to: 1) assess the influence of the antireflux valve on trans-prosthetic reflux (primary outcome); and 2) compare the results of SEMS with and without antireflux valve in terms of reflux symptoms, quality of life (QOL), improvement of dysphagia and adverse events (secondary outcomes). PATIENTS AND METHODS Thirty-eight patients were enrolled in nine centers. Carcinomas were locally advanced (47 %) or metastatic. After randomization, patients received either a covered SEMS with antireflux valve (n = 20) or a similar type of SEMS with no antireflux device but assigned to standard proton pump inhibitor therapy and postural advice (n = 18). Trans-prosthetic reflux was assessed at day 2 using a radiological score based on barium esophagography performed after Trendelenburg maneuver and graded from 0 (no reflux) to 12 (maximum). Monthly telephone interviews were conducted for Organisation Mondiale de la Santé (OMS) scoring from 0 (excellent) to 5 (poor), QOL assessment (based on the Reflux-Qual Simplifié scoring system) from 0 (poor) to 100 (excellent), dysphagia scoring from 0 (no dysphagia) to 5 (complete dysphagia) and regurgitation scoring from 0 (no regurgitation) to 16 (maximum). RESULTS No difference was noted in terms of age, sex, size of lesion, prosthesis length or need for dilation prior to SEMS placement. No difficulty in placing SEMS nor complications were noted. Radiological scores of reflux were found to be significantly lower in patients with an antireflux stent compared to the conventional stent and associated measures. The regurgitation scores were significantly decreased in patients with antireflux stents during the first 2 months after stent placement and thereafter, they were similar in the two groups. QOL and dysphagia were improved in both groups. Survival rates were comparable in the two groups. CONCLUSIONS No difference was observed between the two types of SEMS regarding the palliation of dysphagia and improvement of QOL. However, SEMS with an antireflux valve were more effective in preventing trans-prosthetic gastroesophageal reflux but at the cost of an increased likehood of minor adverse events (migrations and/or obstruction of the SEMS).

Abstract
BACKGROUND AND STUDY AIMS Endoscopic submucosal dissection (ESD) is a technique for "en bloc" resection of superficial tumors of the gastrointestinal tract. In France, experience with this technique is still limited. We wanted to assess the development of ESD in France, with special attention to short term outcomes. PATIENTS AND METHODS Members of the Société Française d'Endoscopie Digestive (SFED) who declared performing ESD reported their cases prospectively on a voluntary basis. Demographic, clinical, and technical data, and the results of immediate complications were collected. Case reports were completed prospectively by each investigator before pooled analysis. RESULTS A total of 188 consecutive case reports were collected from 16 centers. The median case mix per center was 6 patients (range 1-43). The lesion sites treated by ESD were the stomach (n = 75), esophagus (n = 27), duodenum (n = 1), cecum (n = 2), right colon (n = 3), transverse colon (n = 5), sigmoid (n = 3), and rectum (n = 72). The median size of the lesions was 26 mm (range 2-150 mm). En bloc resection was achieved in 77.1% of cases, with complete R0 resection in 72.9%. Histopathology results showed high grade dysplasia or superficial cancer in 71.2%. The median duration of ESD was 105 minutes (range 20-450 minutes). The short term morbidity was 29.2% including 34 cases of perforation (18.1%), and 21 hemorrhages (11.2%) during the 24 hours following ESD, 89% of which were managed conservatively or endoscopically. CONCLUSION In this early experience, the feasibility of ESD appeared to be good but R0 resection and complication rates did not match those reported by Japanese authors and must be improved by an extended practice.

Abstract
BACKGROUND Colon capsule endoscopy (CCE) is a new, non-invasive technology. AIM To conduct a prospective, multicentre trial to compare CCE and colonoscopy in asymptomatic subjects enrolled in screening or surveillance programmes for the detection of colorectal neoplasia. METHODS Patients underwent CCE on day one and colonoscopy (gold standard) on day two. CCE and colonoscopy were performed by independent endoscopists. RESULTS A total of 545 patients were recruited. CCE was safe and well-tolerated. Colon cleanliness was excellent or good in 52% of cases at CCE. Five patients with cancer were detected by colonoscopy, of whom two were missed by CCE. CCE accuracy for the detection of polyps ≥ 6 mm was 39% (95% CI 30-48) for sensitivity, 88% (95% CI 85-91) for specificity, 47% (95% CI 37-57) for positive predictive value and 85% (95% CI 82-88) for negative predictive value. CCE accuracy was better for the detection of advanced adenoma, in patients with good or excellent cleanliness and after re-interpretation of the CCE videos by an independent expert panel. CONCLUSIONS Although well-tolerated, CCE cannot replace colonoscopy as a first line investigation for screening and surveillance of patients at risk of cancer. Further studies should pay attention to colonic preparation (Clinicaltrial.gov number NCT00436514).

Abstract
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. RESULTS Overall, 1335 EMRs in 1210 patients were reported by 241 of the 736 gastroenterologists who performed such procedures (33 %). Resections were done for upper gastrointestinal lesions in 125 cases (41 esophageal, 43 gastric, and 41 duodenal lesions), in 45 % of cases using specific EMR techniques such as ligation, cap, or traction. The technique for resecting the 1210 lower gastrointestinal lesions mostly consisted of saline-assisted polypectomy or EMR, with specific techniques used in only 2.2 %. En bloc resection was less common with esophageal (46 %) or duodenal (54 %) neoplasms than in the lower gastrointestinal tract (73 %); size also had some influence (53 % > 1 cm vs. 92 % ≤ 1 cm). The overall complication rate was 5.2 %; the rate was lower for lesions 1 cm or smaller (0.6 % vs. 4.6 %). Fifty-four early and 17 delayed complications were recorded, in 12 % of upper gastrointestinal and 4.6 % of colonic lesions. Surgery became necessary in 1.6 % for upper and 2.9 % for lower gastrointestinal neoplasms. No association was seen between physician EMR caseload and either en bloc resection rate or complication rate. CONCLUSIONS EMR in general, especially saline-assisted polypectomy in the colon, appears to be reasonably safe even when performed by nonexperts. EMR for larger or for upper gastrointestinal lesions should probably be limited to high-volume centers.

Abstract
This review considers the evolving role of endoscopic techniques in the treatment of obesity, and developments in minimally invasive procedures in endoscopy, endoluminal surgery and natural orifice transluminal endoscopic surgery (NOTES). Endoscopic approaches that are similar to surgery but less invasive, relying on gastric restriction and/or malabsorption, show some promise. Intragastric injection of botulinum toxin is also considered, as is the role of minimally invasive bariatric endoscopic interventions. Gastrointestinal stimulation with implanted electrodes may have potential in the treatment of obesity and endoscopic applications have a role to play in post-surgical interventions. Evolving research into endosurgical approaches is described. Current work on the feasibility of a NOTES approach to bariatric procedures is described.

Abstract
The worldwide epidemic of obesity is forecast to worsen with a concomitant increase in the burden of co-morbid conditions. Bariatric surgery has some disadvantages, and intragastric balloons (IGBs) represent a generally safe, reversible and less invasive approach to weight reduction, based on occupying gastric space to enhance the sensation of satiety. A literature review found that the majority of the published data on IGBs relates to the Bioenterics intragastric balloon (BIB). The evidence for the efficacy of the BIB as a primary means of weight loss is still unconvincing, but it appears to have value in subgroups of patients, for example to improve quality of life, ameliorate co-morbidities, or provide a bridge to surgery. Regarding other IGBs, even if there are promising weight loss results, more evidence and development is generally needed: it is difficult to evaluate the Heliosphere Bag because of the limited clinical experience; the Adjustable Totally Implantable Intragastric Prosthesis (ATIIP)-Endogast may have problems associated with the percutaneous endoscopic gastrotomy (PEG)-type insertion method; the Semistationary Antral Balloon (SAB) may require technical improvements; and the Silimed Gastric Balloon (SGB) warrants further investigation. Another implantable device, the endoscopic duodenal-jejunal sleeve is based on a different concept, that of mimicking bariatric surgery; it effectively bypasses the duodenum and jejunum, and shows promising results. Other endoscopically implantable devices, such as the "Butterfly" and tubular membranes are at an experimental stage.

Abstract
BACKGROUND AND STUDY AIM Polyp miss rates during colonoscopy have been calculated in a few tandem or back-to-back colonoscopy studies. Our objective was to assess the adenoma miss rate while limiting technique or operator expertise biases, i. e. by performing a large multicenter study, with same-day back-to-back video colonoscopy, done by two different operators in randomized order and blinded to the other examination. PATIENTS AND METHODS 294 patients at 11 centers were included. Among the 286 analyzable tandem colonoscopies, miss rates were calculated in both a lesion- and patient-based analysis. Each of these rates was determined for polyps overall, for adenomas, and then for lesions larger than 5 mm, and for advanced adenomas. Univariate and logistic regression analysis were performed to define independent variables associated with missed polyps or adenomas. RESULTS The miss rates for polyps, adenomas, polyps > or = 5 mm, adenomas > or = 5 mm, and advanced adenomas were, respectively, 28 %, 20 %, 12 %, 9 % and 11 %. None of the masses with a carcinomatous (n = 3) or carcinoid component (n = 1) was missed. The specific lesion miss rates for patients with polyps and adenomas were respectively 36 % and 26 % but the corresponding rates were 23 % and 9.4 % when calculated for all 286 patients. The diameter (1-mm increments) and number of polyps (> or = 3) were independently associated with a lower polyp miss rate, whereas sessile or flat shape and left location were significantly associated with a higher miss rate. Adequacy of cleansing, presence of diverticula, and duration of withdrawal for the first procedure were not associated with adenoma miss rate. CONCLUSIONS We confirm a significant miss rate for polyps or adenoma during colonoscopy. Detection of flat polyps is an issue that must be focused on to improve the quality of colonoscopy.

Abstract
BACKGROUND AND STUDY AIMS Duodenal stenting has become a popular treatment in cases of malignant stenosis. However, a prospective evaluation of the efficacy and morbidity of this procedure has not been performed. A prospective multicenter study of duodenal stenting was conducted by the Société Française d'Endoscopie Digestive (SFED). PATIENTS AND METHODS A total of 51 patients were selected (mean age 72), the majority (69%) having pancreatic adenocarcinoma. Palliative treatment was chosen because of irresectability (61.2%), inoperability (18.4%), or both (20.4 %). Enteral Wallstent prostheses were used, and the patients were followed up on day 3, after 1 month, and then every month, with weight measurement, and symptomatic and laboratory evaluation. RESULTS One prosthesis was sufficient in 46 patients. Stent positioning and deployment were correct in 50/51 patients (98%). Twenty patients also underwent biliary stenting in addition to the duodenal stenting. On day 3, 43 patients (84%) were able to tolerate soft solids or a full diet. Six complications were attributed to stenting: three intestinal hemorrhages, two cases of peritonitis due to bowel perforation, and one case of septicemia, and these led to five deaths (mortality 9.8%). Stent dysfunction was observed in 12 cases (23.5%) after a mean delay of 75 days, comprising 11-malignant obstructions and one migration: a new stent was inserted inside the first one and was effective in eight cases; and no treatment was given in the other four patients because of their clinical state. The median survival was 71.5 days. CONCLUSIONS Palliative endoscopic treatment of malignant duodenal stenosis using metallic prostheses is highly feasible, even with associated biliary stenting. Symptomatic improvement is fast. However, the mortality and the obstruction rate are high, suggesting that a prospective trial comparing this treatment with surgery is still required.

Abstract
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. A prospective multicenter study was therefore conducted to evaluate the efficacy and disadvantages of covered Wallstents. PATIENTS AND METHODS Covered Wallstents were implanted endoscopically in 62 patients with inoperable distal malignant biliary obstruction. Complications, stent patency, and patient survival were analyzed. RESULTS Stent insertion was achieved in 61 of the 62 patients (98.4 %). Procedure-related complications were observed in four patients, consisting of minor pancreatitis (n = 2) and abdominal pain due to stent expansion (n = 2). There was no procedure-related mortality. Seven patients died too early for proper assessment, so that a total of 54 patients were ultimately evaluated. Stent dysfunction occurred in 17 of the 54 patients (31.5 %). The reasons for dysfunction were proximal tumor overgrowth (n = 5), migration (n = 3), lithiasis or food impaction (n = 3), cholangitis without the need for a repeat biliary intervention (n = 5), and unknown (n = 1). The median period of stent patency was 142 days. No tumor ingrowth was observed. Acute cholecystitis was diagnosed in five patients (10 %) and was responsible for one death. Three stents were successfully removed. CONCLUSIONS Covered biliary metal stents are effective for the drainage of distal malignant biliary obstruction, with a dysfunction rate apparently similar to that of uncovered stents. However, the risk of acute cholecystitis appears to be a major concern with this type of stent in patients with gallbladder in situ. Further comparative studies are needed.

Abstract
Ursodeoxycholic acid, employed in treatment of intrahepatic cholestasis as seen in primary biliary cirrhosis, primary sclerosing cholangitis, and chronic hepatitis; does not have marketing approval for prescription during pregnancy because of lack of data. In 3 cases of gravidic cholestasis, we administered oral ursodeoxycholic acid 1 g a day from the 34th week of amenorrhea to delivery. In each case, it took 3 days of treatment for the pruritus to regress incompletely and for plasma levels of biliary acid and transaminases to decrease. The infants, born between the 36th and 38th week of amenorrhea, presented with no problem. Forty-eight cases of gravidic cholestasis treated by ursodeoxocholic acid (0.4 to 1 g a day) have been reported in the literature; 18 cases belonging to 2 randomized studies. In 46 cases pruritus disappeared generally 3 days after treatment onset, and plasma level of biliary acid and transaminase decreased in one week. Only two patients experienced persisting pruritus despite biological improvement. No foetal adverse effect is reported. Ursodeoxycholic acid seems to be an efficient treatment of gravidic cholestasis. Long term observation of fetuses exposed in utero to this treatment is required to assess safety.

Abstract
A case is reported of a duodenal perforation by a Kimray-Greenfield filter hook in a 66-year-old female patient. This device had been inserted four years before, after a pulmonary embolism. The patient presented with epigastric pain, vomiting and extracellular dehydration with renal failure. A plain abdominal film showed the filter to be tilted 15 degrees to the left, with an opening 28 mm wide. Various investigations were carried out, none of which providing a satisfactory diagnosis. Steroid treatment (1 mg.kg-1 x day-1 of prednisone) was started before admission to intensive care. Only at that time gastroduodenoscopy showed on of the filter's hooks jutting through the duodenal wall. This perforation was located in the posterior wall of the third part of the duodenum, and was associated with an ulcer of the mucosa facing this hook. The diagnosis was confirmed by an abdominal CT scan. The hook was cut and the perforation sealed off during a first laparotomy. Twenty-six days later, the patient developed intestinal obstruction due to a haematoma of the jejunal wall. She later had a cerebrovascular accident, with status epilepticus and deep coma. She died four months after her admission. The late complications of vena caval filters are discussed. The position of these devices should be regularly checked by a plain abdominal film. Abdominal CT scanning is a useful investigation for the diagnosis of intra and extravascular complications.

Abstract
The rare instance of a gastrointestinal hemorrhage caused by a lithiasis of the duct of Wirsung is described. The world literature records only 13 other cases. Pancreatic calculi cause hemorrhage by either migrating through the pancreatic parenchyma to perforate the duodenum, ulcerating the vessels of the periductal parenchyma, or rupturing the pancreas. The usual sign of this complication of chronic calcifying pancreatitis, difficult to diagnose, is repeated gastrointestinal hemorrhages and sometimes pain, as in epigastric colitis. The immediate therapy is control of the hemorrhage. With transcatheter occlusive techniques, radical surgery can be postponed until it is more tolerable.

Abstract
An autosomal recessive disorder, abetalipoproteinemia or Bassen-Kornzweig disease, concerning two sisters are described. This disorder, clinically similar to Friedreich ataxia, should be examined by electrophysiological and laboratory procedures because of the possibility of treatment by high doses of vitamin A and E. The routine electrophysiological examination of the two sisters revealed a degenerative spinocerebellar and peripheral nervous process which confirmed the damage of large myelinated fibers, as reported in the literature: neurogenic muscular atrophy of distal muscles, polyphasic motor unit potentials, moderately decrease of lower motor and sensory nerve conduction rates, and reduced amplitude of evoked responses in sensory nerves and muscles. We stress out the diagnostic value of the heterogenous conduction decrease in the distal motor fibers, signs of processes of demyelination or distal regeneration.

Abstract
To determine the relationship between gastroesophageal (GE) reflux and pulmonary disease, we studied 21 asthmatics, 30 chronic bronchitics, 6 patients with GE reflux and no pulmonary symptoms, and 10 control subjects; GE reflux was diagnosed by pH monitoring and GE scintiscanning. Frequency of GE reflux in the asthmatics was 57%; in chronic bronchitis it was 56%. Pulmonary function tests did not show any differences between patients with or without reflux. The GE reflux episodes were more numerous but shorter in asthmatics than in chronic bronchitis. Patients with digestive symptoms alone were no different from chronic bronchitis with respect to reflux. The mechanism whereby reflux triggers pulmonary problems was investigated using the following 2 tests: scintiscan for pulmonary aspiration, and esophageal acid infusion (0.1N HCI). Six pulmonary aspirations were detected. Only asthmatics, with or without reflux, showed any significant variations in maximal expiratory flow at 50% and 25% of VC after HCI infusion. Thus, our results show that asthmatics differ from bronchitis patients by the characteristics of their reflux.

Abstract
The cases of two sisters with abetalipoproteinemia are reported. Both presented the complete clinical and biological features of the disease: ataxia, retinitis pigmentosa, lack of apolipoprotein B, chylomicrons, LDL and VLDL, reduced titers of serum cholesterol and triglycerides, acanthocytosis, very low levels of serum vitamin A and E. Abetalipoproteinemia is a rare autosomal inherited disease. It is usually revealed during early childhood by steatorrhea and failure to thrive; ataxia and retinitis pigmentosa appear later. The originality of these two cases stems from: 1) their late and fortuitous diagnosis: the first sister was investigated at the age of 42 after the discovery of a vitamin K induced coagulation disorder. The other sister was 39 when she was routinely examined as a family member; 2) the presence of constipation without any other suggestive digestive complaint. However, white discoloration of the duodenal mucosa seen at endoscopy and lipid droplets within the intestinal absorptive cells at biopsy were characteristic. Barium studies showed diffuse involvement of the small bowel which was displaced by an enlarged sigmoid. Treatment consists of administration of vitamin A and vitamin E which prevent or delay ocular and neurologic symptoms. Vitamin K is associated whenever necessary.

Abstract
The authors report a case of meningo-encephalitis in a 28 year-old man, who was hospitalized in emergency after a generalized epileptic crisis, which occured after a period of fever and neuro-psychiatric troubles. This was followed rapidly by a comatose stage (third grade). All investigations to find an etiology were unsuccessful except: positive toxoplasmosis serology at 720 IU/ml with IgM fluorescent antibodies, then at 2 600 IU/ml. The level of fluorescent antibodies in the CSF was 1/16. Clinical evolution was favorable with resolution of the comatose stage, and disappearance of the meningitis.
