Laparoscopic surgery in hepatic hydatid cysts: a technical improvement

Abstract

Hepatic hydatid cysts are a common surgical problem that is encountered in many tropical countries, including India. Open surgical exploration and excision had been the mainstay of treatment until the advent of laparoscopy. In 1998, we successfully managed six cases of large hepatic hydatid cysts using the videoendoscope, with excellent postoperative follow-up results. Four men and two women participated in this study, with patient ages ranging from 28 to 42 years. The duration of the disease ranged from 1.3 to 2.8 years. All patients had undergone preoperative albendazole therapy for more than 2 months. Complete evacuation of the cyst contents, including all daughter cysts and laminated membrane, along with a subtotal excision of the extrahepatic part of the cyst wall, was accomplished without any spillage into the peritoneal cavity. The saucerized cavity was drained. The drains were removed 6 to 9.4 days after a check ultrasound. Postoperative follow-up ranged from 3 to 9 months and revealed no evidence of a recurrence in the abdomen. It is possible with carefully planned placement of trocars to completely eliminate the risk of spillage, and therefore not compromise the standard principles of hydatid surgery.
