BACKGROUND Capsule endoscopy has involved a significant advance in techniques for imaging of the small bowel. Its most frequent indication is for studying patients with obscure gastrointestinal bleeding (OGIB). Small bowel tumors are infrequent, representing only 1% to 3% of all malignant gastrointestinal tumors. This study aimed to assess retrospectively(More)
Cancer is caused by a variety of factors whose study requires a large amount of data. Compiling these data is an expensive and time-consuming task which can be carried out in a better way with the support of Information and Communication Technologies (ICT). However, most epidemiologic studies take place without this support of informatics or with basic(More)
Although manometry is used with increasing frequency to evaluate the effectiveness of different treatments for achalasia, the criteria for a successful manometric response have not been well defined. Manometric responses were collected before and after 43 treatments in 35 patients with achalasia in order to determine manometric changes after different(More)
OBJECTIVES The endoscopic capsule is a useful tool for visualizing the small bowel in patients with obscure gastrointestinal bleeding. In this study the authors evaluated the diagnostic aid provided by the endoscopic capsule, the factors predicting a significant finding and their impact on the patients' clinical evolution. METHODS A total of 100 patients(More)
Diverticular disease is the most frequent cause of lower gastrointestinal bleeding. Most of the times, bleeding stops without any intervention but in 10-20% of the cases it is necessary to treat the hemorrhage. Several modalities of endoscopic treatment have been described after purging the colon. We present five cases of severe diverticular bleeding(More)
BACKGROUND Stent placement is effective in relieving malignant colonic obstruction. Nevertheless, the technique may offer difficulties in sharply angulated lesions. METHODS Guidewire insertion assisted with a sphincterotome was performed in 4 patients with intestinal obstruction caused by malignant colonic strictures. The manipulation of the(More)
BACKGROUND Endoscopic sphincterotomy without cholecystectomy is a therapeutic option in selected patients after acute biliary pancreatitis. We conducted a prospective evaluation of the long-term effects of sphincterotomy in terms of the need for of subsequent cholecystectomy and the recurrence of gallstone pancreatitis. METHODS We studied 88 patients with(More)
BACKGROUND AND STUDY AIMS Several studies have shown that the use of the Witzel dilator is an effective and safe treatment for achalasia. However, the optimal values for pressure, number of dilations, and duration of application have not yet been established. The aim of this study was to determine these three parameters. PATIENTS AND METHODS 43 patients(More)
