Early outcomes of robotic transabdominal preperitoneal inguinal hernia repair: a retrospective single-institution study in Korea

Abstract

Purpose: Robotic hernia repair has increased in popularity since the introduction of da Vinci robots (Intuitive Surgical). However, we lack quantitative analyses of its potential benefits. Herein, we report our initial experience with robotic transabdominal preperitoneal (R-TAPP) inguinal hernia repair. Methods: We retrospectively reviewed the data from patients who underwent R-TAPP inguinal hernia repair with a prosthetic mesh using the da Vinci platform. Data on patient characteristics and surgical outcomes were also collected. Results: Twenty-one patients (including 20 male patients [95.2%]) with a mean age of 54.1 ±16.4 years and body mass index of 23.8 ± 1.9 kg/m2 underwent R-TAPP inguinal hernia repair. Bilateral hernia repair was performed in two patients (9.5%), and six patients (28.5%) with scrotal hernia underwent R-TAPP hernia repair. A sigmoid colon sliding hernia was present in three patients (14.3%). The mean operation and console times were 91.8 ± 20.4 minutes and 154.5 ± 26.2 minutes, and 61.4 ± 16.9 minutes and 128.0 ± 25.5 minutes for unilateral and bilateral inguinal hernia, respectively. Spermatic vessel injury was identified intraoperatively in one patient. Two minor postoperative complications, postoperative ileus, and wound seroma were reported. The mean duration of hospitalization was 3.8 ± 0.9 days. No recurrence or conversion to open surgery was required. Conclusion: Our findings suggest that R-TAPP inguinal hernia repair is safe and feasible. Its cost-effectiveness, optimal procedural steps, and indications for a robotic approach require further investigation.
