Objective To investigate causes of recurrence of hepatic cysts after laparoscopic fenestration. Methods We retrospectively summarized the experience of 54 cases of hepatic cysts treated with laparoscopic fenestration from June 1998 to August 2003. Results A follow-up in 52 cases for 1~6 years found 5 cases of recurrence, the recurrence rate being 9.6% (5/52). Among the 5 cases, the artificial opening had been made too small in size in 3 cases because of unusual position of the cysts, the septum within the lesion had not been fully opened in 1 case, and the recurrence of polycystic liver was confirmed in 1 case. Conclusions Improper selection of patients, too small fenestration of cyst, omission of multiple cysts and inappropriate management of mucous membrane are main causes leading to the recurrence.
