Robotic Incisional Hernia Repair After Robotic-assisted Radical Prostatectomy (RARP): A 3-port Approach

Background/Aim: Incisional hernia is a complication that occurs occasionally, and surgical intervention is required to prevent more severe sequela. While there are several options for management, robotic-assisted incisional repair has not been well discussed yet. We herein report a case series of 10 patients who underwent robotic-assisted incisional hernia repair (RIHR) after robotic-assisted radical prostatectomy (RARP). The aim of the study was to examine the feasibility of incisional hernia repair with da Vinci (R) robotics. Patients and Methods: We recruited patients from a group of 2,000 consecutive patients who underwent RARP from December, 2005 to June, 2020 by a single surgeon. Patient characteristics included age, body mass index (BMI), PSA level, pathology Gleason score, and pathology TNM staging. The variants regarding the patients' incisional hernia included incisional hernia occurrence time after RARP, defect size, operation time, console time, blood loss, and follow-up time after the herniation occurrence. Furthermore, we established a defect size of 3x2 cm(2) as the cutoff value for using mesh reinforcement or not. Results: The mean defect area was 27.7 cm(2), and the average operative time was 114.8 min, with a mean console time of 87 min. Blood loss was 32.5 ml, and the hospital stay for all patients was 3 days without complications. The mean follow-up period was 29.5 months, with no recurrence. Conclusion: RIHR is a feasible surgical method that is not inferior to the traditional open or laparoscopic repair. Furthermore, RIHR can possibly lessen the burden of both the surgeon and patient.
