Management of Giant Liver Cysts

BackgroundLiver cysts are often asymptomatic. Symptomatic liver cysts are uncommon and can be managed by percutaneous aspiration, laparoscopic/open marsupialization, or resection. Our aim is to review our experience with management of giant liver cysts (GLC).Materials and MethodsAn IRB approved chart review of patients with liver cysts between 1995–2009 was performed. There were 34 GLC in 24 patients, 20 (83%) were females (mean age of 59.2 y). Pain was the main symptom in 20 patients. The average cyst size was 15.66cm (6–32cm) with 14 cysts over 15cm in size. Two patients with GLC (11 and 15cm) decided not to have surgery; 16 patients underwent laparoscopic surgery with one recurrence. One patient with laparoscopic marsupialization at another center was managed by open marsupialization and repair of the bile leak. Four of the patients underwent open marsupialization and one underwent open resection. Four patients with prior percutaneous aspiration had recurrences (100%), three underwent laparoscopic and one open marsupialization. An 8-wk pregnant patient underwent percutaneous aspiration of a 32cm cyst to alleviate symptoms until delivery.ResultsThe mean hospital stay for laparoscopic marsupialization was 5.57 d compared with 9.2 d for open procedure. Three (18.7%) postoperative complications (bile leak, recurrence, bleeding) occurred in the laparoscopic group, and one (20%) bile leak in the open group, with a mean follow-up of 41 mo.ConclusionLaparoscopic marsupialization of GLC is as effective and safe as open procedures in preventing cyst recurrence regardless of cyst size and location, and affords a relatively shorter hospital stay.
