Early operative outcomes and learning curve of robotic assisted giant paraesophageal hernia repair.

Background: We have previously described our technique of robotic-assisted giant paraesophageal hernia repair (RA-GPEHR). The purpose of this study was to report our initial experience, early outcomes and learning curve with RA-GPEHR using a four-arm robotic platform.

Methods: 24 consecutive patients presenting with symptomatic giant paraesophageal hernias (GPEH) underwent RA-GPEHR from April 2011 to February 2014. Peri-operative data and short-term patient outcomes were assessed by retrospective review of a prospectively maintained database.

Results: Median age was 62 years (range 44-84). 15 (63%) patients underwent fundoplication and 9 (37%) gastropexy. Median procedure time was 277 min (range: 185-485) and decreased steadily over the experience. There were no intra-operative complications or surgical mortality. No patients experienced dysphagia in the early post-operative period.

Conclusions: RA-GPEHR is safe, with reported short-term operative and functional outcomes similar to conventional laparoscopic approaches. The initial learning curve appears relatively short for experienced minimally invasive esophageal surgeons. Copyright © 2016 John Wiley & Sons, Ltd.
