[Alcoholic hepatitis: prospective clinical study of 20 cases].
(National Institutes of Health, 1984) G Bonifaz; J Lora; Tatiana Morell Paz
Twenty cases of alcoholic hepatitis were registered in a Gastroenterology Service during a two year span (from February 1980 to February 1982). The obstructive clinical pattern was predominant in an important number of the cases her reported. This is a remarkable situation for a clinical pathological correlationship to avoid indicating surgery for this type of patients. It is noticeable that the quantities and time of alcohol ingestion are below the levels indicated in medical papers used as reference. It is suggested that altitude hypoxia may be the cause for our patients being more liable to alcohol injury. Symptoms and laboratory findings were similar to the accepted patterns of reference works.
[Digestive changes in cholecystectomized patients].
(National Institutes of Health, 1982) Freddy Leonardo Pavón Patiño; R Ponce; J Lora; C Aguilar; Juan José Guillermo Ríos
An important number of cholecystectomized patients after some years of complete well-being, begin complaining of symptoms such as periodic diarrhea or constipation, abdominal pain, regurgitation, vomiting, etc. The purpose of this study is to try to identify an alteration or lesion in the stomach or colon in cholecystectomized patients of more than five years standing, which may be causing the aforementioned condition. The forty patients under observation, free of biliary tract post-operative lesions, were subjected to: hemogram, amylasemia, either infusion cholangiograph or ERCP, fecal parasitological-tests, upper digestive and colon X Ray series, esophagus, stomach and duodenal endoscopy with biopsies. Additionally, ten underwent a colonoscopy which also included biopsy. The result of the radiological, amylasemia and hemogram studies was normal in all cases. The parasitological tests were negative. In every case, a moderate to severe superficial, chronic gastritis was found as well as minor histopathological alterations in the colon mucosa. The presence of bile in both duodenum and colon in interdigestive periods, alterations in the enterohepatic circulation as well as in the biliary composition itself, are suggested as the possible causes of the patients symptoms.

Elevated gastric lesions, represent an important group among gastric pathology. To establish its incidence in our experience, we studied the endoscopic reports of two important hospitals in La Paz city: Instituto de Gastroenterología Boliviano Japonés and Hospital Obrero No. 1. In order to make a good endoscopic diagnosis among different elevated lesions we use some parameters like: location, shape, size, diameter, surface of the lesion and surrounding mucosa and characteristics of the falls. 10.472 endoscopic reports were reviewed, 497 elevated gastric lesions were found, 475 corresponded to mucosal lesions (352 benign lesions and 123 malignant lesions), 11 to submucosal and 11 extragastric lesions.
Megacolon at high altitude.
(National Institutes of Health, 1983) Freddy Leonardo Pavón Patiño; R Ponce; J Lora; Christopher Aguilar; J Ríos Dalenz
Megacolon occurs frequently in high altitude areas. This report describes observations made in 60 cases seen in La Paz, Bolivia (3,600 meters above sea level). Motility of both the large and small bowel was found to be increased and the feces had a low pH. No histologic abnormalities were noted in the nervous plexus or smooth muscle. It is assumed that megacolon in these circumstances is acquired and not congenital.
