[Clinical analysis of robot-assisted laparoscopic transabdominal preperitoneal inguinal hernia repair].

Objective: To explore the clinical value of robot-assisted laparoscopic transabdominal preperitoneal (TAPP) inguinal hernia repair. Methods: We performed a retrospective review of 23 consecutive patients who underwent robotic inguinal hernia repair from January 2018 to December 2019 at Beijing United Family hospital. The patients were all male with mean age 48.8 (17-72) years and BMI 25.8 (21.2-32.6)kg/m(2). Data examined included perioperative bleeding, operative times, length of stay, pain scale ratings and postoperative complication. Results: There were no major complications during the surgeries including no significant intraoperative bleeding, injury to the vas deferens or major vascular structures. There were no conversions to open. No patients received prophylactic antibiotics according to our hospital policy. No surgical site infections were found. All patients were discharged home within the 24-hour postoperative period. The mean operating time of 13 cases of unilateral hernia was 121 (82-165) min, and that of 10 cases of bilateral hernia was 166 (100-315) min. The mean intraoperative blood loss was 13.3 ml (5-25 ml). The average pain score in recovery was 0.96 (0-3). The total length of stay was 28.4 (24.2-37.5) h. During a follow-up period of 3-18 months, none of the patients experienced a recurrent hernia. None experienced chronic pain or discomfort in the operative field. Conclusions: The robotic surgical platform facilitates a new safe, minimally invasive approach to groin hernia. Because of improved ergonomics, visualization and wristed instrumentation, the robotic approach enabled creation of larger peritoneal flaps and had the potential for less injuries. The major advantage to the patient is a shorter hospital stay, and more rapid postoperative recovery and decreased postoperative pain, lower complications and recurrences.
