Laparoscopic treatment of hepatic hydatid cysts

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.

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.

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.

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.
