The present study was performed to describe a single-center experience with upper gastrointestinal stents.

Methods: All patients at a single center who had an SEMS placed for the treatment of obstruction over a 3-year period were retrospectively evaluated.

The Effect of Preoperative Oral Carbohydrate Solution Intake on Patient Comfort: A Randomized Controlled Study.

Purpose: The study was conducted to investigate the effect of preoperative oral carbohydrate loading on the preoperative discomforts and postoperative complications of patients undergoing elective thyroidectomy.

Design: A randomized controlled clinical trial.

Methods: Ninety patients scheduled for thyroidectomy were divided into three groups: (1) those receiving a carbohydrate-rich drink (CHD), (2) those receiving an overnight 5% glucose intravenous infusion, and (3) those fasting from midnight.

Colonoscopic perforations: Single center experience and review of the literature.

Objective: Iatrogenic colonic perforation is a well-known complication that can increase mortality and morbidity in patients undergoing colonoscopy. Closer follow-up and a well-planned treatment strategy are required when perforation arises as a complication. The aims of this study are to (1) report our experience with a large colonoscopy series; (2) evaluate the underlying mechanisms of iatrogenic colonic perforation; (3) discuss the ideal period between onset and treatment; and (4) review the current literature regarding the management of iatrogenic colonic perforations.

First Video Case Report of Chronic Retrograde Jejunojejunal Intussusception after Subtotal Gastrectomy with Braun's Anastomosis.

Intussusception, which is seen rarely in adults, is defined as the pulling or invagination of a part of the intestine into another segment of the intestine. In this case report we present chronic retrograde jejunojejunal intussusception following gastric surgery with Braun's anastomosis in adult with video presentation. A 66-year-old woman, who had undergone gastric surgery 39 years ago and cholecystectomy 20 years ago, was admitted to our clinic with the complaints about weight loss, abdominal pain, nausea, and vomiting.
