BACKGROUND Obstruction of the afferent or efferent limbs of a gastrojejunal anastomosis is a potential complication after pancreaticoduodenectomy (PD) resulting in either gastric outlet obstruction or afferent limb syndrome. The use of self-expanding metal stents for the management of anastomotic strictures after resection of pancreatic cancer has not been well studied. We present four such cas...

BACKGROUND The safety of drug-eluting stents has been called into question by recent reports of increased stent thrombosis, myocardial infarction, and death. Such studies have been inconclusive because of their insufficient size, the use of historical controls, a limited duration of follow-up, and a lack of access to original source data. METHODS We performed a pooled analysis of data from fo...

Aortoesophageal fistulas are a rare but commonly fatal complication of esophageal cancer. Reports of successfully managed cases are few, with high mortality and morbidity usually resulting from failure to control the initial massive haemodynamic insult. We report the case of a 47-year-old Caucasian man with recently diagnosed advanced esophageal cancer who suffered an episode of massive haemate...

BACKGROUND AND PURPOSE In carotid artery stent placement, marked oversizing of the stent relative to the internal carotid artery lumen is common. This study was performed to determine the influence of using oversized self-expanding nitinol stents on neointimal hyperplasia. METHODS In six greyhound dogs, 24 self-expanding nitinol stents (eight SMART stents, eight Easy Wallstents, eight Sinus-F...

BACKGROUND Ovarian cancer is usually diagnosed at an advanced stage, most often co-occurring with malignant bowel obstruction. Affected patients are generally in poor physical condition, and it is important to manage the bowel obstruction to improve quality of life. CASE REPORT We present the case of a 75-year-old woman who underwent a left hemicolectomy for an ovarian carcinoma with bowel ob...

A 49-year-old man with a history of type 2 diabetes mellitus, chronic renal failure, and sigmoid adenocarcinoma underwent a laparoscopic left hemicolectomy. A second surgery was necessary after unsuccessful endoscopic dilation of an anastomotic stricture located 12cm from the anus. After five further surgical procedures for different complications, a repeat anastomosis was necessary at 5cm from...

Patients with pancreatic cancer frequently suffer from both biliary and duodenal obstruction. For such patients, both biliary and duodenal self-expandable metal stent placement is necessary to palliate their symptoms, but it was difficult to cross two metal stents. Recently, endoscopic ultrasonography-guided choledochoduodenostomy (EUS-CDS) was reported to be effective for patients with an inac...

Endoscopic stents have evolved dramatically over the past 20 years. With the introduction of uncovered self-expanding metal stents in the early 1990s, they are primarily used to palliate symptoms of malignant obstruction in patients with inoperable gastrointestinal (GI) cancer. At present, stents have emerged as an effective, safe, and less invasive alternative for the treatment of malignant GI...

temesis and melena. He had received an uncovered nitinol self−expanding metal stent (SEMS) 2 months previously for in− operable obstructive hilar cholangiocar− cinoma. Upper endoscopy revealed a normal esophagus, stomach, and duodenal bulb. At the duodenal wall opposite the papilla, a large ulceration with hematin spot (l" Fig. 1) had formed as a result of SEMS impaction. We decided to shorten ...
