Background: To compare tension-free hernia repair to a modified Bassini technique (Andrew’s technique) used to treat complicated inguinal hernia. Methods: In the period 1990–2004, 75 patients were submitted to emergency operation because of strangulated inguinal hernia. 33 patients underwent tension-free repair utilizing a polypropylene mesh (group A),(More)
BACKGROUND Pancreatic cancer is generally not amenable to curative resection, and self-expanding metallic stents have been used to relieve obstruction of bile duct and duodenum in patients with unresectable pancreatic cancer. However, both relative experience with sequential or simultaneous endoscopic stents placement in biliary and duodenal stricture and(More)
BACKGROUND EMR traditionally performed by using normal saline solution (NS) plus epinephrine (E) as a submucosal fluid cushion does not maintain the submucosal elevation for a prolonged time. It was hypothesized that 50% dextrose (D(50)) plus E as a hypertonic, inexpensive, and easily available solution might be an ideal alternative for producing and(More)
BACKGROUND Ingested foreign bodies and food bolus impaction are frequently seen in endoscopic practice. Successful foreign body and food bolus removal may depend on the method used, the choice of device, and the experience level of the endoscopist, although few papers report experience and outcome of tertiary centers. AIM To investigate the effectiveness(More)
Endoscopic polypectomy is at the forefront of colorectal cancer (CRC) prevention. However, endoscopic polypectomy is not completely free of complications, with bleeding being one of the most common complications encountered. In view of the ongoing campaign to introduce colorectal cancer screening to the population, addressing the issue of colonoscopic(More)
BACKGROUND The advantages of laparoscopic surgery have been well documented. However, the impact of pneumoperitoneum on sepsis sequelae is still equivocal. This study aimed to evaluate the effect of CO(2) pneumoperitoneum, applied under different pressures and exposure times, on sepsis cascade and mortality. MATERIAL AND METHODS In 42 New Zealand rabbits,(More)
AIM To compare diverse endoscopic interventions in the management of occluded uncovered self-expanding metal stents (SEMSs) that had been placed for palliative treatment of unresectable malignant biliary obstruction. METHODS A retrospective review was undertaken in 4 tertiary endoscopic centers to determine optimal management of different types of(More)
A 76-year-old diabetic man underwent cholecystectomy for gangrenous calculous cholecystitis. His postoperative course was complicated by the development of Candida albicans esophagitis necessitating antifungal therapy, and total parenteral nutrition (TPN) for 15 d. Seven weeks after cholecystectomy, he presented with cholangitis. Endoscopic retrograde(More)
BACKGROUND Proximal or distal migration of a plastic biliary stent is uncommon, but its management can be a technical challenge to the pancreatobiliary endoscopist. PATIENTS AND METHODS All cases (n=51) of proximally and distally migrated plastic biliary stents over an 8-year period at 3 referral pancreaticobiliary centers were included in this(More)
BACKGROUND Normal saline (NS) plus epinephrine (E) is the traditionally used solution as submucosal fluid cushion for a safe and effective endoscopic mucosal resection (EMR) of sessile colorectal polyps. It was hypothesized that hydroxyethyl starch (HES), an inexpensive and easily available solution might be an ideal solution for prolonged elevation of(More)
