BACKGROUND AND AIM Estimation of small bowel length is of interest following the recent development of device-assisted enteroscopy. This new technology allows access to the deep small bowel, but rates of examination of the entire small bowel (total enteroscopy) differ between study populations. Variation in small bowel length could factor into this observed irregularity in total enteroscopy rat...

Conventional endoscopic exams do not allow the entire visualization of the gastrointestinal (GI) tract. Push enteroscopy (PE) is an effective diagnostic and therapeutic procedure, although it only allows exploration of the proximal small bowel (Pennazio et al., 1995). Simultaneously, convetional colonoscopy is limited at the terminal ileum. Therefore, prior to the wireless capsule endoscopy era...

Wireless Capsule Endoscopy (WCE) is one of the latest technologies that has evolved in the area of medical endoscopy. The far old endoscopy techniques such as colonoscopy push enteroscopy and intraoperative enteroscopy helped doctors to visualize up to stomach, from the upper part and terminal ileum and colon from the bottom. There exists no method to view most of the small intestine without su...

BACKGROUND AND STUDY AIMS The small intestine is a potential origin of bleeding in patients with unexplained gastrointestinal tract hemorrhage or iron-deficiency anemia. Most reports on the investigation of these patients describe the use of upper tract enteroscopy. The diagnostic yield of combined upper and lower enteroscopy has not been widely assessed and remains to be clarified. The aim of ...

Obscure gastrointestinal tract bleeding (OGIB) is a common and challenging issue [1]. Here we present an extremely rare case of overt OGIB secondary to impacted bone fragment within a small-bowel diverticulum. An 88-year-oldman presentedwith hypotension and a 2-day history of marooncolored stools. Initial hemoglobin concentration was 7.7g/dL. Urgent upper endoscopy showed a large duodenal diver...

Small bowel diverticulum is a rare cause of gastrointestinal bleeding. The diagnosis and treatment of small bowel diverticular hemorrhage is clinically challenging before the development of deep enteroscopy. In this multicenter study from the Taiwan Association for the Study of Small Intestinal Diseases (TASSID), 608 patients underwent deep enteroscopy for obscure gastrointestinal bleeding duri...

the gastrointestinal tract to evaluate because of its long length, complex looped configuration, and also because of its distant location. Only the proximal portion of the jejunum and the terminal ileum can be examined with the use of upper gastrointestinal endoscopy and colonoscopy. Thus, other examination tools such as small bowel follow-through, enteroclysis, capsule endoscopy and double-bal...

the cytology study is effective and reliable technique in intraoperative consultation. this study was performed to evaluate the accuracy of the cytology study in intraoperative consultation of the breast lesions. 125 specimens of the breast lesions were examined and studied in imam khomeini hospital during the years 1998-99. the sensitivity, specificity and accuracy for cytological method were ...
