Abstract

Purpose: Laparoscopy is considered the treatment of choice for hepatic cysts, especially those located in anterolateral segments (AL; segments II, III, IVb, V, and VI) because of the ease of laparoscopic access. Here, we evaluated the feasibility and safety of laparoscopic treatment of hepatic cysts in posterosuperior segments (PS; segments I, IVa, VII, and VIII).
Methods: We retrospectively analyzed clinical data for 34 patients who underwent laparoscopic treatment of hepatic cysts between September 2004 and December 2012. Patients were divided into two groups depending on whether the main largest cyst was located in AL (n = 20) or PS (n = 14). Laparoscopic cyst unroofing was performed in 29 patients with symptomatic simple cysts. Laparoscopic resection was performed in 5 patients with suspected cystic neoplasms.
Results: There were no deaths or major complications. The mean operation time was 110 minutes and the mean hospital stay was 4.4 days. The mean cyst size was not significantly different (P = 0.511) but the frequency of multiple cysts was significantly greater in group PS (P = 0.003). The predominant type of resection was unroofing in both groups (P = 0.251). The mean blood loss (P = 0.747), mean hospital stay (P = 0.812), mean operation time (P = 0.669), morbidity rate (P = 0.488), and relapse rate (P = 0.448) were not significantly different. Relapse occurred in one patient who underwent reunroofing 17 months later. The median follow-up is 62 months.
Conclusion: Laparoscopy is a safe procedure for hepatic cysts located in posterosuperior segments.
