Bile leakage presenting as acute abdomen due to a stone created around a migrated surgical clip.

Background: Surgical clips may migrate into the common bile duct after surgery for cholecystolithiasis leading to usually early or middle-term complications.

Case Report: A 31-year-old woman, 6 years after laparoscopic cholecystectomy, developed acute abdomen and choloperitoneum after rupture of a secondary bile duct and bile leakage. This complication was due to a solitary common bile duct stone.

High prevalence of Helicobacter pylori infection and monoclonal gammopathy of undetermined significance in patients with chronic idiopathic neutropenia.

The prevalence of Helicobacter pylori infection was evaluated in 120 patients with chronic idiopathic neutropenia (CIN), 8 patients with monoclonal gammopathy of undetermined significance (MGUS) associated with CIN, and 74 age- and sex-matched normal volunteers, all derived from the same geographical area. The purpose of the study was to investigate the possible causal relationships of H. pylori infection with the development of MGUS in CIN patients.

Natural course of inoperable esophageal cancer treated with metallic expandable stents: quality of life and cost-effectiveness analysis.

Background And Aim: The aim of this study was to evaluate the efficacy and safety of endoscopic therapy with self-expanding metallic endoprostheses in the management of malignant esophageal obstruction or stenosis and the cost-effectiveness of the method in patients suffering from primary esophageal carcinoma. All patients with inoperable esophageal cancers treated with either laser palliation or endoprosthesis insertion were studied retrospectively.

Method: Between May 1997 and December 2002 obstruction of the esophagus was diagnosed in 78 patients (52 male, 26 female, age range 53-102 years, mean 72.

Binge drinking and nitric oxide metabolites in chronic liver disease.

Aims: The effect of binge drinking in the production of nitric oxide metabolites has not been studied in patients with chronic viral liver disease.

Methods: We therefore studied serum levels of nitrites and nitrates (NOx) in 13 patients with chronic viral hepatitis and nine patients with compensated viral cirrhosis, after administration of 80 g alcohol. 15 patients with compensated alcoholic cirrhosis and seven healthy individuals were used as controls.
