The purpose of this clinical study was to evaluate the usefulness of laparoscopic fenestration of symptomatic liver cysts. Between September 1996 and September 2001, 6 patients underwent laparoscopic fenestration for symptomatic hepatic cysts. All 6 patients were women. The mean age was 59.5 (range 40-74). Two patients had single and 4 had multiple cysts. The mean diameter of the lesions, measured by preoperative computed tomography (CT), was 16.8 cm (range 10-20). The indications for surgical treatment included abdominal fullness associated with pain or dyspepsia. The surgical procedure involved puncture and aspiration of the cyst and subsequent circular electroresection of the cystic wall. Laparoscopic fenestration was successfully done in all 6 patients. The operating time was 148 minutes (range 110-215). Mean blood loss was 93 mL (range 5-300). Histologic examination of the cyst wall showed 5 simple cysts and 1 papillary serous cystadenoma. There were no intraoperative or postoperative complications. The mean hospital stay after surgery was 4.3 days (range 3-5). Complete relief of symptoms was achieved in 5 patients during the postoperative follow-up (range 2-6 years, mean 4). Follow-up CT (1 month to 4 years) has shown regression of the cysts in all patients (mean 3.8 cm, range 2-8). Laparoscopic fenestration of symptomatic liver cysts is a simple and effective method to relieve symptoms with minimal surgical trauma.
