[Lipoma of the small intestine. A clinical case].

The paper reports a case of a 45-year-old female with long-standing anemia, recurrent abdominal pain and subocclusive crises. Following a negative endoscopy of the upper tract of the large intestine, barium enema and angiography, the patient underwent total colonoscopy. Massive bleeding from the ileal valve suggested an ileal pathology: a small intestine enema confirmed a polypoid proliferation 60 cm above the Bahuino valve with related ileal invagination 25 cm long. The patient underwent surgery and pathological findings revealed a 7 cm-wide ileal lipoma near a small angiodysplasia. The latter seemed to be the cause of bleeding. The diagnosis of small intestine tumours is made difficult by the fact that the only important signs are abdominal pain, intestinal bleeding and subocclusive crises, which are common symptoms in many pathologies. The authors stress the importance of a thorough endoscopic examination and selective angiography.

[Laser therapy in the treatment of tumors of the rectum and inoperable sessile polyps. Personal case series].

The Authors report on their experience in endoscopic laser photoablation (Nd-YAG laser) of advanced, non surgical rectosigmoid tumors, large sessile adenomas and their recurrence after polypectomy. 37 patients have been studied: 21 out of them had an advanced rectosigmoid tumor, 10 out a large sessile adenoma, and the remaining 6 had a recurrence of adenoma after polypectomy. All the rectosigmoid tumors improved either clinically or symptomatically after 2-4 laser treatments. In 2 cases stenosis occur after laser therapy but no dilatation was necessary. Large adenomas and recurrence were all cured by the laser treatment, with a recurrence rate of about 30% at six months. In conclusion, endoscopic laser treatment is a safe and effective technique for the treatment of benign sessile rectosigmoid tumors and for palliation of symptoms from malignant ones in selected non surgical patients.

Histological aspects and healing rates of gastric ulcers treated with omeprazole 20 mg once daily or ranitidine 150 mg B.I.D.

The aim of this double blind trial was to compare omeprazole 20 mg once daily with ranitidine 150 mg b.i.d. in treatment of benign gastric ulcer, evaluating both rates and histological aspects of the ulcer healing process. Eighteen patients were randomized, 9 to each treatment; one patient (ranitidine group) was excluded from the analysis because of malignant ulcer. Omeprazole appeared to be more effective than ranitidine in healing gastric ulcer. A more rapid relief of symptoms was observed in the omeprazole group than in the ranitidine group. Both drugs reduced chronic atrophic gastritis (with a trend in favour of omeprazole), while omeprazole showed a prompter activity on the components of acute inflammation.
