The efficacy of laparoscopic lauromacrogol sclerotherapy in the treatment of simple hepatic cysts located in posterior segments: a refined surgical approach

Hepatic cysts in located posterior segments close to the diaphragm (IVa, VII, and VIII) reportedly have a high recurrence rate. Presently, laparoscopic omentoplasty is the accepted technique; developed from laparoscopic deroofing, which places a viable pedicle flap of omentum to prevent cyst closure. However, potential adhesions have made laparoscopic omentoplasty less favorable. In this paper, we report on an improved surgical technique involving lauromacrogol sclerosis directly under laparoscopic fenestration. We also review and evaluate the efficacy and feasibility of this refined surgical approach.
