Introduction: Paraesophageal hernia repair (PHR) has seen a dramatic evolution with the introduction of laparoscopic surgery and its feasibility and clinical outcomes well demonstrated. The adoption rate of robotic-assisted PHR has not been as widely accepted. In analyzing the University Health data of 12,079 patients, robotic fundoplication repair made up 2.8% of all operations with open repair at 18% and laparoscopic at 79.2%. The same data demonstrated higher costs in open surgery due to increased length of stay and complications compared to robotic-assisted surgery. The purpose of our study is to share our experience with one of the largest retrospective series in robotic PHR in a non-university, minimally invasive surgery fellowship program. Furthermore, our training model is able to achieve excellent patient outcomes.
Methods: A retrospective chart review was performed of 135 large minimally invasive PHRs between January 1st 2008 – August 1st, 2016. The data was filtered for Da Vinci robot-assisted PHR. This data was then analyzed to assess the patient characteristics, surgical methodology, fellow participation, as well as outcomes.
Results: Out of a total of 135 cases utilizing a minimally invasive approach, 44 patients in our series underwent a robotic PHR. The hiatal hernia types: four (9.1%) type 2 , 36 (81.8%) type 3, and four (9.1%) type 4. The average age of patients was 67 years old and median American Society of Anesthesiologist (ASA) class of III. All cases were performed with robotic-assistance , however, one case required conversion to laparoscopy. Three patients were revisional cases and two patients had concomitant bariatric procedures. Twenty-seven patients (61.4%) had a Nissen fundoplication, 12 (27.2%) patients had a partial fundoplication, and five (11.4%) had no fundoplication. Six patients had mesh reinforcement. Fellows participated in 82.9% of robotic-assisted cases. The average length of stay was 3.1 days. Two (4.5%) patients suffered perioperative complications including reintubation and transfusion of one unit of blood. No mortalities were noted in our series.
Conclusion: The utilization rate of robotic-assisted surgery in foregut has been well described, but still under utilized compared to open surgery. Our series demonstrates the ability to achieve comparable outcomes to laparoscopic surgery utilizing robotic-assistance in a fellowship training environment. Further investigation into open to laparoscopic and robotic surgery learning curves could highlight described advantages to robotic surgery and advance patient surgical care.
