[Treatment of gastroesophageal reflux by pexis to the round ligament. Report of 100 operated patients followed-up for 16 to 23 years].

In a study of 1,491 patients operated with ligament cardiopexy from 1,694 onwards, which we published in 1986, we reviewed 100 consecutive cases operated 15 years earlier or more. The review was based on a radioclinical (100), fiberscopic (53) and manometric (71) study, as well as on a measurement of the pH in doubtful cases (22). The results were distributed into categories A (normal), B (occasional disorders), C (functional disorders without recurrence) and R (recurrence), as follows: A + B 81%, C 12% and R 6%.

[Supraselective or proximal gastric vagotomy. Report of 1,250 surgical cases. 777 special cases with objective follow-up for over 10 years].

From August, 1970 to February, 1989, we performed 1,105 elective and 145 emergency PGVs (proximal gastric vagotomy). The emergent cases included 118 perforations and 27 bleeding lesions. Since September, 1973, we have been able to measure the pH of the mucosa using a GR282C transesophageal electrode.

[Hernial strangulation of Meckel's diverticulum: Littre's hernia. Apropos of 4 cases].

Hernial strangulation of Meckel's diverticulum (Littre's hernia) is a rare anatomoclinical form. It represents 10% of all complications of Meckel's diverticulum (8.8% of our cases), and complications like hemorrhage, perforation and diverticulitis are fairly frequent.

[Antiulcerogenic properties of bran rice oil in rats].

A study was made of the effect of rice chaff oil (ASA) on gastroduodenal ulcer (UGD) induced by different techniques: cysteaminium chloride, indomethacin, artificial gastric juices and stress (acidity, histamine, pepsin and volume of gastric juice were evaluated). For each technique the same protocol was followed: four days before the experiment 20 Wistar rats (180-220 g) were divided into a control group (0.2 ml/day of saline solution per os) and a treated group (0.

A statistical approach to an individualized prognostic index (IPI) for breast cancer survivability.

The authors present 611 and 262 case histories of patients with breast cancer, studied 5 and 10 years after mastectomy, respectively; 27 clinical and 10 histologic parameters were considered for the statistical evaluation, in order to define an Individualized Prognostic Index (IPI) for breast cancer survivability. The probability of survival was estimated by a Bayesian formula using selected prognostic parameters, these parameters were placed in order of discriminant resolution and, for the calculation of the IPI, were selected according to their importance, as it follows: 5 years after surgery: percent affected nodules, dermal infiltration, TNM phase, Scarff-Bloom index and evolutive outbreak (PEV); 10 years after surgery: TNM phase, dermal infiltration, percent affected nodules and Scarff-Bloom index. The current information considers that out of several parameters, the selected prognostic parameters used for the IPI are sufficient to establish probability tests and a reliable estimation of life expectancy following breast cancer surgery.
