Introduction: the capsule endoscopy (CE), from his approval, has become a first line diagnostic procedure for the study of the small bowel disease. The aim of this study is to report our experience since the implantation of this technique in our hospital. Material and methods: retrospective review of the CE undertaken in Department of Endoscopy. There was gathered in every case the age, sex, motive of consultation, previous diagnostic procedures, capsule endoscopy findings and complication of the technique. One took to end a descriptive and analytical analysis. Results: there was achieved a total of 416 explorations in 388 patients. The obscure gastrointestinal bleeding was the most frequent indication (83.30%) followed by suspected Crohn's disease (7.5%). Angiodisplasia was the endoscopic lesion more frequently detected (42.2%), especially, in patients with digestive bleeding of obscure origin (OR 3.13 p < 0.001), followed by the flebectasia (10.6%) and the ulcer suspicious of Crohn’s disease (9.9%). The global diagnostic yield as for the detection of injuries was 77.34% with a case of "not defecation of the capsule' and therefore need of laparotomy. Conclusions: the capsule endoscopy is a technique consolidated and as his potential is known, his indications are extended. The obscure gastrointestinal bleeding is the most frequent indication and the angiodisplasia the most identified injury. Once known his diagnostic yield, larger studies are needed that assess the influence of capsule endoscopy on clinical outcoumes.

Although intussusception is the most frequent cause of intestinal obstruction in children, it only represents 5-10% of all adults. The preoperative diagnosis is difficult and it is rarely done by endoscopy. We present a case of adult ileocolic intussusception caused by an ileon terminal hamartoma. The diagnosis was done by colonoscopy.

Retrospective study on 617 foreign bodies (FB) located in the upper digestive tract in the years 1981, 1988 and 1989. Of them pertain 541 to adults (greater than 14 years) and 76 to children (less than or equal to 14 years). The youngest was a girl aged 11 months and the oldest, a male aged 98. In adults, the most frequently encountered FB was impacted food. In children, coins. Clinical findings in adults were mainly dysphagia or FB sensation. In children it is more frequent that another person sees the child swallowing or notices the absence of any object. In adults, its most frequent location was Killian's recess. In children it was the stomach. The removal was achieved in 96% of adults and 100% of children. There weren't any serious complications and mild ones were 0.55%.

In the Central Endoscopy Service of the "San Carlos" University Hospital 218 therapeutic endoscopy procedures have been performed during 1988-1989 in patients with non-variceal upper digestive hemorrhage. Ages of patients were between 6 and 95. Bleeding was more frequent in men over 50. The majority of procedures were done in the first 12 hours (48%), Type IIa Forrest lesions were identified in 57% of cases and gastric and duodenal locations were about the same. Melena was seen in 40%, hematemesis in 28% and both in 32% of patients. In 53% adrenalin and absolute alcohol were injected and in 24% BICAP techniques, in the remaining patients combined procedures were used. Procedures were successful in 93% of cases. No complications were recorded.
