Histological benefit of retreatment by pegylated interferon alfa-2b and ribavirin in patients with recurrent hepatitis C virus infection posttransplantation.

We conducted a study to evaluate the efficacy of pegylated interferon/ribavirin in patients who did not respond to previous posttransplant recurrent HCV treatment with IFN/ribavirin combination. Twenty-seven patients were consecutively included in this study and retreated with pegylated interferon alfa-2b (1.5 microg/kg/week) with ribavirin (800-1000 mg daily) for 48 weeks for genotype 1 and 4 and 24 weeks for other genotypes. We compared them with 21 untreated patients enrolled during the same period. Primary endpoint was the SVR and secondary endpoint was histological evaluation 24 weeks after ending therapy. Twenty-seven patients started therapy but 2 (7%) stopped because of side effects. On an intent-to-treat basis, eight patients (30%) had an SVR. Cyclosporine as immunosuppressive therapy during antiviral therapy (p = 0.03) and EVR (p = 0.02) were significantly associated with viral clearance. In 46 patients in whom paired graft biopsies were available, fibrosis score was improved in 76% of treated patients versus 5% in untreated patients. Among treated patients, improvement of fibrosis was not correlated to SVR. Our data show that 30% of patients who have failed prior posttransplantation treatment achieved an SVR when retreated with pegylated interferon alfa-2b/ribavirin. More interesting is that fibrosis score was improved in 65% of treated patients despite failure of HCV eradication.

[Barrett's oesophagus: place of antireflux surgery].

The aim of this study was to review the literature about the effect of antireflux surgery on the metaplasia-dysplasia-adenocarcinoma sequence in patients with Barrett's oesophagus. Antireflux operations (by laparotomy or laparoscopy) can alter the natural history of Barrett's oesophagus, allowing disease stabilization in a substantial proportion of patients without high grade dysplasia at time of surgery. It also may induce complete or partial regression of Barrett's epithelium, especially for short segment of Barrett's oesophagus, but in unpredictable manner. While regression of low-grade dysplasia is commonly observed, histologic progression is rarely observed after effective antireflux surgery. However, ineffective antireflux surgery expose to histologic progression to high-grade dysplasia or adenocarcinoma. These data support the need for a long-term clinical, endoscopic, and histologic follow-up program after antireflux surgery in patients with Barrett's oesophagus.

[Gastrojejunocolic fistula, report of two recent cases with original management].

Gastrojejunocolic fistulae, ultimate complication of anastomotic peptic ulceration, are presently uncommon. We report two recent cases of postoperative gastrojejunocolic fistulas (after duodenal ulcer surgery and total duodenopancreatectomy), which were complicated at time of diagnosis (acute peritonitis and liver cirrhosis) and required a two-stage treatment.

Oesophageal and gastric bile exposure after gastroduodenal surgery with Henley's interposition or a Roux-en-Y loop.

BACKGROUND: The degree which the various reconstruction techniques prevent bile reflux after gastroduodenal surgery has been poorly studied. METHODS: Bile exposure in the intestinal tract just proximal to the jejunal loop was measured with the Bilitec 2000 device for 24 h after gastroduodenal surgery in three groups of patients. Group 1 comprised 24 patients with a 60-cm Henley's loop after total gastrectomy. Group 2 included 31 patients with a 60-cm Roux-en-Y loop after total (22 patients) or subtotal (nine) gastrectomy. Group 3 contained 21 patients with a 60-cm Roux-en-Y loop anastomosed to the proximal duodenum as part of a duodenal switch operation for pathological transpyloric duodenogastric reflux. Bile exposure, measured as the percentage time with bile absorbance greater than 0.25, was classified as nil, within the range of a control population of healthy subjects, or pathological (above the 95th percentile for the control population). Reflux symptoms were scored and all patients had upper gastrointestinal endoscopy. RESULTS: Bile was detected in the intestine proximal to the loop in none of 24 patients in group 1, eight of 31 in group 2 and 12 of 21 in group 3 (P < 0.001). The mean reflux symptom score increased with the degree of bile exposure, and the proportion of patients with oesophagitis or gastritis correlated well with the extent of bile exposure (P < 0.001). CONCLUSION: A long Henley's loop was more effective in preventing bile reflux than a long Roux-en-Y loop. Bilitec data correlated well with the severity of reflux symptoms and the presence of mucosal lesions.

[Laparoscopic pancreatic resections].

The feasibility of laparoscopic pancreatic resection has been demonstrated. However, the real clinical benefit for the patients remains questioned. The best indication for a laparoscopic approach appears to be the resection of benign or neuro-endocrine tumors without a need for pancreato-enteric reconstruction (i.e enucleation or distal pancreatectomy). The use of the laparoscopic approach for malignant tumors still remains controversial. The benefits of minimally invasive surgery are clearly correlated with the successful management of the pancreatic stump. Pancreatic related complication rate (fistula and collection) is 15% when using pancreatic transection with a laparoscopic endostappler.
