RESUMO
Se compara la rareza relativa de la obstruccion intestinal ocasionada por calculos biliares en pacientes mexicanos con la informada en series de otros autores, y se analizan etiopatogenia, hallazgos clinicos y radiologicos y revision de dos formas de tratamiento quirurgico: enterolitotomia aislada y enterolitotomia mas reparacion de la fistula colecistoenterica. Se informan tres casos del padecimiento y se concluye que factores que afectan la mortalidad por el mismo incluyen diagnostico incorrecto, observacion prolongada, edad avanzada del enfermo, padecimientos acompanhantes y tecnica operatoria inadecuada.mas reparacion de la fistula colecistoenterica.

365 appendicectomy cases performed from 1972 to 1976 were studied prospectively. In 135 control cases the wound was not lavaged. In 102 cases the wound was lavaged with normal saline solution. En 108 cases the wound was lavaged with PVP-I. Wound abscess formation rate in the first group was 28.8%, in the second group was 21.35% and in the third group was 18.5%. Patients operated after 1974 and treated with PVP-I showed a 4.2% abscess formation. Morbility and mortality in appendicitis are best reduced if early diagnosis and surgical treatment are backed by a faultless technic.

During a cholera epidemic, Vibrio cholerae was isolated from two springs which supplied mineral water to a spa and to a commercial water bottling plant. Epidemiologic investigation found that cholera attack rates were 10-fold greater among visitors to the spa than among non-visitors. A subsequent matched-pair case-control study which excluded persons who had visted the spa showed that a history of consumption of the bottled non-carbonated water was significantly more common among bacteriologically confirmed cholera cases than among paired controls.
