A study was carried out of 137 patients with a diagnosis of acute appendicitis who were randomized to either laparoscopic or open appendicectomy. Patients found to have perforated or normal appendices at histological examination were excluded. Fifty-two patients undergoing laparoscopic appendicectomy and those receiving 57 open procedures were analysed.(More)
Although laparoscopic appendectomy for uncomplicated appendicitis is feasible and safe, its application to perforated appendicitis is uncertain. A retrospective study of all patients with perforated appendicitis from 1992 to 1999 in a university hospital was performed. A series of 231 patients were diagnosed as having perforated appendicitis. Of these(More)
The safety and efficacy of laparoscopic cholecystectomy for acute cholecystitis were evaluated in a 2-year retrospective review. Results of laparoscopic cholecystectomy in 66 patients with acute inflammation of the gallbladder were compared with those of the standard open procedure for this condition (43 patients) and routine laparoscopic cholecystectomy(More)
BACKGROUND To determine the predictive factors of synchronous common bile duct (CBD) stones, data from 878 consecutive patients who underwent cholecystectomy in a university clinic from June 1991 to June 1996 were retrospectively analyzed. METHODS Based on clinical, biochemical, and ultrasonographic criteria, 194 patients were selected for ERCP, 180(More)
Use of the laparoscopic approach for the management of gastric cancer is still in the developmental phase. The authors present their experience with laparoscopic radical gastrectomy for advanced gastric cancer. Between September 1997 and August 1999, four laparoscopic gastrectomies for gastric carcinoma were performed on two male and two female patients(More)
A double papilla of Vater, with separate openings for the bile duct and the pancreatic duct, is a rare anatomic anomaly observed in endoscopic retrograde cholangiopancreatography (ERCP). We report the case of a 45-year-old Chinese man with obstructive jaundice due to common bile duct stones and gallbladder stones. During ERCP, a double papilla of Vater with(More)
BACKGROUND Several studies have reported the feasibility of using 'needlescopic' instruments with a diameter less than 3 mm in minimally invasive surgery. This study reports a comparison of needlescopic cholecystectomy and laparoscopic cholecystectomy. METHODS Seventy-five patients with symptomatic chronic cholelithiasis were randomized to needlescopic (n(More)
This report describes the technique of totally intra-abdominal Billroth II gastrectomy. Because the procedure is minimally invasive, patient recovery is remarkable compared with the conventional open technique. The development of this procedure completes the minimally invasive revolution in the management of peptic ulcer disease, which began with the(More)
BACKGROUND AND STUDY AIMS Hematochezia is a common clinical problem. When the bleeding is brisk and continuous it requires prompt hospital admission and careful diagnostic evaluation and management. Colonoscopy has become the first-line investigative modality in patients presenting with severe hematochezia in many centers, including ours. A retrospective(More)
Five hundred twenty four consecutive barium enemas done over an 18-month period were reviewed in Singapore to ascertain the prevalence and distribution of diverticular disease in the large bowel. In this study, the prevalence rate was 20 percent, which is comparable to European and American studies but higher than similar studies in Asian countries.(More)
