We reviewed 50 patients with benign tumors of small intestine treated over a period of 15 years. Mean age was 58 years, and 54% of the patients were female. The most frequent location of the tumors was the jejunum (54%). The commonest histological variety was leiomyoma (56%), followed by fibroma (14%). Average size of tumor was 4.8 cm. With regard to clinical data, 20% of the patients were asymptomatic; in the remaining 80% of the patients, abdominal pain, gastrointestinal hemorrhage and abdominal distension were the most frequent symptoms. The mean symptom-diagnosis interval was 2 months. Barium studies, duodenal endoscopy and selective angiography were the most useful diagnostic tools. However, only in 30% of cases the correct diagnosis was reached preoperatively. All patients underwent surgical treatment. The more frequent surgical technique was segmental resection of small bowel (84%). Operative mortality was 4% and morbidity was 10%. Actuarial 5-year survival for all patients was 96%.

An evaluation was made of 34 patients having Barrett's oesophagus. Medical therapy consisted of antacids, H2 blockers, orthopramides, and postural measures (20 cases, mean follow-up 2.9 years). A Nissen fundoplication was done in 14 cases (mean follow-up 2.5 years). Clinical, endoscopic and histologic evaluation was done in all patients and pH measurements also done in all operated cases. Clinical results have been excellent in 70% of medically treated patients and in 100% of surgically treated ones, pH measurements were between normal limits in all operated patients. However, recovery of the normal epithelium did not occur in any case, except for some partial improvement in one patient treated surgically.

The diagnosis of Mallory-Weiss syndrome was made in 142 patients with upper gastrointestinal haemorrhage by early endoscopy. These patients represent 5.16% of all patients with haemorrhage treated in our unit over a period of ten years. Emergency surgery was needed in 13 due to persistent haemorrhage. In the remaining 129, conservative management sufficed to stop the bleeding. All patients receiving medical therapy survived while one of the surgically treated patients died of pulmonary thromboembolism in the early postoperative period.

A series is presented of 152 patients diagnosed over a 9-year period by endoscopy and biopsy as Barrett's esophagus. We analyzed epidemiological data and the risk of malignancy, and calculated the prevalence and incidence in our series.
