title: The results of surgery in amebic liver abscess: experiences in eighty-three patients.
abstract: Experiences with surgery in 83 patients with amebic liver abscess are presented. The patients' ages ranged from 8 months to 72 years; 85% were men. Symptoms had been present for an average of 4.6 weeks. In 36 (43%) the abscess already was ruptured at the time of admission to the hospital and in an additional eight it ruptured later. Rupture occurred more commonly upward through the diaphragm than downward, and into a serous cavity in 36 patients. Because of the poor general condition and associated illnesses of the patients, surgical procedures were limited to the minimum. Indications for operation were rupture or impending rupture of the abscess, failure of response to medical therapy, and inadequacy of aspiration of left lobe abscess. An additional 27 patients underwent operation because of diagnostic problems or symptoms of an acute abdomen. Two thirds of the patients had one or more complication. The overall mortality rate was 34%. Factors adversely affecting mortality rate were lack of preoperative drug therapy, rupture into a serous cavity, and presence of an associated amebic perforation of the colon.
