[A comparative study of cisapride versus metoclopramide in the treatment of symptomatic hiatal hernia].

Comparative study of the therapeutical effects of cisapride and metoclopramide in 50 patients with symptomatic hiatal hernia was performed. Behaviour of media before and after treatment, of resting pressure and relaxation lower esophageal sphincter, pressure of the primary wave and the number of reflux episodes with pH < 4. The group of patients treated with cisapride had a considerably higher beneficial effect (p < 0.

[Diagnosis of acute abdomen by means of laparoscopy (experience in 6,400 cases)].

A study of 6,400 cases of Emergency Laparascopy (E.L.) was made in the Instituto de Gastroenterología de Habana, Cuba.

[Emergency fibroendoscopy. Basic exploration in the diagnosis of upper digestive bleeding (experience in 200 cases)].

Prognosis in upper gastrointestinal hemorrage (UGIH) depends mostly upon an early diagnosis. The addition of an around the clock endoscopist on duty in the hospital was decided upon to provide inmediate evaluation of all UGIH.

[Fibroesophagogastroduodenoscopy in the gastroenterology institute (experience in 8,000 cases)].

The results of 8,000 fiber-optic endoscopic procedures performed at the Gastrenterologic Institut during a 5 year period are analyzed in this paper. This extensive was possible not only because the method is simple and innocous due to the flexibility and high technology of these apparatue, but also because the Cuban Public Health System made feasible the exploration without expenses for all the patients needing it. Thirty-two percent of the explorations in an ever greater scale in the search for gastric cancer in its early stages.
