title: [Ascariasis of the gallbladder. Report of 2 cases and review of the literature].
abstract: Two patients who complained of a clinical picture compatible with cholelithiasis; and in whom the diagnosis of ascariasis of the gallbladder was made sonographically, are reported. In the first patient, cholecystectomy was curative and corroborated the presence of the roundworm. In the second patient, piperazine citrate was given. A second sonogram performed after therapy showed no roundworm within the gallbladder; and the patient remains asymptomatic until now. The usefulness of ultrasonography in the diagnosis of gallbladder ascariasis, and during surveillance in those patients who are managed with medical therapy only, is emphasized.
