Laparoscopic treatment of hepatic hydatid cysts

Abstract

Background: Because of limited experience worldwide, controversies about the laparoscopic treatment of liver hydatid cysts have not been resolved. The aim of this study was to describe the technical details of a laparoscopic method we developed in 1992 and report the initial results from an endemic area.

Methods: Of the 30 consecutive patients with 33 liver hydatid cysts considered for laparoscopic treatment during a 6-year period at a university hospital in Turkey, conversion to an open procedure was required in 7 patients (23%) while 23 patients with 25 cysts were able to be treated laparoscopically.

Results: By using a special trocar to suspend the cyst against the abdominal wall, laparoscopic simple drainage was performed in 16 patients (70%) and unroofing and drainage in 6 patients (26%). Pericystectomy was performed in 1 patient (4%). Complications were observed in 1 patient (4%) perioperatively and 4 patients (17%) postoperatively. Eleven patients (48%) were followed-up for a mean of 17 months (range, 3-72 months) and 1 recurrence (9%) was detected.

Conclusions: This report is a very large experience with the laparoscopic treatment of liver hydatid cysts in the literature. We have established a technique yielding a comparable morbidity and recurrence rate to open series in early follow-up. We advocate that it is a safe and simple technique with potentially a decreased risk of intra-abdominal spillage compared with the other laparoscopic methods described.
