Laparoscopic deroofing of nonparasitic XXXX with or without greater omentum flap.

@entity1 @entity96
BACKGROUND: Laparoscopic deroofing is the standard therapy for simple nonparasitic @entity96 . The operation is performed with or without a greater omentum flap sutured into the former cyst cavity. The aim of this study was to determine whether a greater omentum flap has influence on the recurrence rate of nonparasitic @entity96 during the long-term follow-up. METHODS: From September 1999 to November 2009, 23 @entity1 underwent laparoscopic deroofing for single or multiple nonparasitic symptomatic @entity96 . A greater omentum flap to fill the former cyst cavity was used in 8 @entity1 , whereas in 15 @entity1 operation was carried out without such an omentum flap. The @entity1 were identified retrospectively and subject to a follow-up examination. The 2 groups of @entity1 were compared according to the recurrence of the @entity96 . RESULTS: The median follow-up time was 59  40 months. There was an overall recurrence rate of 4.3% (1 of 23), with 1 cyst recurrence in the greater omentum flap group (1 of 8). The Fisher exact test showed no difference in the recurrence rate between the 2 groups (P=0.35). CONCLUSION: The overall recurrence rate is low. A greater omentum flap to prevent a local cyst recurrence after laparoscopic deroofing is dispensable and is a potential source of additional complications.
