Robotic Inguinal Hernia Repair (TAPP) First Experience with the New Senhance Robotic System

This retrospective study was performed to evaluate the safety and feasibility of the new Senhance Robotic System (TransEnterix Inc., Morrisville, North Carolina) for inguinal hernia repairs using the transabdominal preperitoneal approach.

From March to September 2017, 76 inguinal hernia repairs in 64 patients were performed using the Senhance Robotic System. Patients were between 18 and 90 years of age, eligible for a laparoscopic procedure with general anesthesia, had no life-threatening disease with a life expectancy of less than 12 months, and a body mass index (BMI) < 35. A retrospective chart review was performed for a variety of pre-, peri-, and postoperative data including, but not limited to, patient demographics, hernia characteristics, and intraoperative and postoperative complications.

Fifty-four male and 10 female patients were included in the study. Median age was 56.5 years (range 22-86 years), and median BMI was 25.9 kg/m2 (range 19.5-31.8 kg/m2). Median docking time was seven minutes (range 2-21 minutes), and median operative time was 48 minutes (range 18-142 minutes). Two cases were converted to standard laparoscopic surgery due to robot malfunction and abdominal wall bleeding, respectively. Median length of stay was one day.

We report the first series of laparoscopic inguinal hernia repairs using the new Senhance Robotic System. Compared to conventional laparoscopic transabdominal preperitoneal (TAPP) hernia repairs, there was no significant difference in operative time or perioperative complications. Additionally, there was no significant learning curve detected due to its intuitive applicability. Therefore, the Senhance Robotic System promises broad applicability across a range of laparoscopic general surgical operations.
