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)
AIM To detect the prevalence of small bowel polyps by wireless capsule endoscopy (WCE) in patients with familial adenomatous polyposis (FAP). METHODS We examined prospectively 14 patients with FAP to assess the location, size and number of small-intestinal polyps. Patients' age, sex, years of observation after surgery, type of surgery, duodenal polyps and(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 Endoscopic retrograde cholangiopancreatography (ERCP) is now the exclusive endoscopic therapeutic modality for biliary as well as pancreatic diseases. The aim of the present study was to investigate patient- and procedure-related risk factors for post-ERCP complications in a large-scale study of procedures performed by a single experienced(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)
This study aimed to investigate the efficacy and safety of placing self-expandable metal stents (SEMSs) without fluoroscopy for palliation of malignant esophageal or esophagogastric strictures. From January 2003 to June 2008, a prospective observational study investigated the placement of covered proximal-release Ultraflex stents without fluoroscopy in(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.
