Comparison of robotic versus laparoscopic transabdominal preperitoneal (TAPP) inguinal hernia repair

Despite growing popularity and potential advantages of robotics in general surgery, there is very little published data regarding robotic inguinal hernia repair. This study examines a single surgeon's early experience with robotic TAPP inguinal hernia repair compared with laparoscopic TAPP repair in terms of feasibility and cost. We performed a retrospective review of 63 consecutive patients (24 laparoscopic and 39 robotic) who underwent inguinal hernia repair between December 2012-December 2014 at a single institution by a single surgeon. Data examined included gender, age, BMI, operative times, recovery room times, pain scale ratings, and cost. Patient groups were the same in terms of age and BMI. The mean operative time (77.5 vs 60.7 min, p = 0.001) and room time (109.3 vs 93.0 min, p = 0.001) were significantly longer for the robotic vs the laparoscopic patients. Recovery room time (109.1 vs 133.5 min, p = 0.026) and average pain scores in recovery (2.5 vs 3.8, p = 0.02) were significantly less for the robotic group. The average direct cost of the laparoscopic group was $3216 compared with $3479 for the robotic group. The average contribution margin for the laparoscopic group was $2396 compared with $2489 for the robotic group. Robotic TAPP inguinal hernia repair had longer operative times, but patients spent less time in recovery and noted less pain than patients who underwent laparoscopic TAPP inguinal hernia repair. The direct cost and contribution margin are nearly equivalent. These results should allow the continued investigation of this technique without concern over excess cost.
