Risk factors for gallstone formation in the general population have been well studied while those after weight reduction surgery are unknown. The aim of this study was to identify the risk factors for the development of symptomatic gallstones after bariatric surgery. Retrospective review was performed for patients who underwent laparoscopic Roux-en-Y(More)
Anastomotic complications such as leakage and bleeding remain among the most serious complications of laparoscopic colorectal surgery. No perfect method exists for accurate and reliable avoidance of these catastrophes. This study aimed to study the usefulness of routine intraoperative endoscopy (RIOE) by comparing the surgical outcomes for RIOE patients(More)
Cholelithiasis is a common complication after bariatric surgery. Pure restrictive procedures such as sleeve gastrectomy and gastric banding theoretically should result in less gallstone formation because the food continues to follow the normal gastrointestinal transit, maintaining the enteric–endocrine reflex intact. To the authors’ knowledge, the(More)
Hereditary nonpolyposis colorectal cancer (HNPCC) is an autosomal dominant syndrome. The National Cancer Institute (NCI) has recommended the Revised Bethesda guidelines for screening HNPCC. There has been a great deal of research on the value of these tests in other countries. However, literature about the Chinese population is scarce. Our objective is to(More)
Primary hepatic carcinoid tumours are very rare and less than 60 cases have been reported in the literature. This study reports a 35-year-old female with 2 synchronous primary hepatic carcinoid tumours in her right hepatic lobe. She was examined with various imaging investigations including ultrasound scan, computed abdominal tomography, magnetic resonance(More)
Surgical resection is indicated for gastrointestinal stromal tumour (GIST). Laparoscopic resection with clear margins is effective in gastric GIST. However, GIST located in the posterior gastric wall with close proximity to the oesophagogastric junction poses special challenges. Laparoscopic intragastric resection offers a new approach to the management of(More)
BACKGROUND To study the effects of pantoprazole on gastric pH and recurrent bleeding after endoscopic treatment for bleeding peptic ulcers. METHODS After endoscopic haemostasis, patients were randomly assigned to infusion group (pantoprazole 80 mg i.v. bolus followed by continuous infusion of 8 mg/h for 3 days), bolus group (pantoprazole 80 mg i.v. bolus(More)
BACKGROUND Elective laparoscopic cholecystectomy is recommended after endoscopic clearance of choledocholithiasis for patients with acute cholangitis, according to Tokyo guidelines. However, the optimal timing remains uncertain. METHODS Perioperative outcomes were retrospectively reviewed and compared between patients with early (< 6 weeks) and late (> 6(More)
PURPOSE This study investigated the risk factors related to artificial bowel sphincter infection, complications, and failure. METHOD Complications may occur at any time after artificial bowel sphincter implantation. Early-stage complication is defined as any complications that occurred before artificial bowel sphincter activation, whereas late-stage(More)
Realistic models of colorectal cancer are necessary to study cancer biology and evaluate therapeutic interventions. Real-time observation and repeated sampling of implanted tumor is difficult to achieve in the current orthotopic animal colorectal cancer model. The aim of this study was to establish a simple colostomy implantation mouse model for evaluating(More)
