The case group consisted of a consecutive series of patients who underwent laparoscopic repair for rectal prolapse between February 1993 and June 2000. The control group underwent open prolapse(More)
OBJECTIVE To evaluate the influence of antireflux surgery on gastric emptying. DESIGN Nonrandomized controlled trial 3 months before and after surgical intervention. SETTING Secondary and tertiary referral center. PATIENTS AND CONTROL SUBJECTS Twenty consecutive patients (7 women, 13 men), mean age 49.2 years, with symptomatic, objectively confirmed(More)
OBJECTIVE The purpose of the study was to evaluate the long-term symptomatic and endoscopic outcome in gastroesophageal reflux disease with erosive esophagitis, comparing conservative with operative management.

BACKGROUND The main cause of recurrent reflux symptoms after Nissen fundoplication is disruption of the fundic wrap. Reoperation has shown a lack of scar tissue between the serosal surfaces of the fundic folds in these cases. METHODS Attempts were made to induce serosal scarring during fundoplication performed in rabbits. In group 1 the serosal folds were(More)
OBJECTIVE To elucidate the long-term course of conservatively managed gastroesophageal reflux disease without H2-antagonists or omeprazole. METHODS DESIGN Clinical trial, uncontrolled. SETTING Gastroenterological outpatient department of a teaching hospital. PATIENTS Sixty of 87 patients consecutively referred for severe gastroesophageal reflux(More)
BACKGROUND Open or laparoscopic surgery for gastroesophageal reflux disease gives longterm freedom from symptoms in 83-100% of cases but has a certain percentage of complications.

BACKGROUND Gastro-oesophageal reflux disease (GERD) can be effectively treated pharmacologically or surgically. As GERD is often a chronic condition, we compared the long-term costs of medical and surgical management. METHODS The medical regimens were ranitidine (150 or 300 mg/day), omeprazole (20 or 40 mg/day), and lansoprazole (30 mg/day), with costs(More)
