Robotic fenestration of massive liver cysts using EndoWrist technology.

Abstract

We present the short-term outcomes of robotic fenestration of symptomatic liver cysts using the EndoWrist One Vessel Sealer. Data from patients who underwent robotic deroofing were collected and analysed retrospectively. A total of 17 patients were treated. Mean cyst size was 14cm (median 15cm, range 6.3-24). Seven cysts were in posterosuperior or central segments. There were no mortalities or conversions. Blood loss was minimal in all but one case of 200ml. Mean operating time was 174minutes (median 170min, range 97-335). Mean hospital stay was 2.5days (median 2days, range 1-10). One patient developed a bile leak requiring ERCP. There are no recurrences with a median follow-up of 19months. Robotic fenestration can be safely performed and offers distinct advantages over the laparoscopic approach in the treatment of posterosuperior and perihilar cysts at the expense of longer operating times and increased cost.
