Abstract
INTRODUCTION: Complications unique to laparoscopic surgery have been reported, including port site hernia. We experienced a case of port site hernia in the robotic right-hand port site measuring 8 mm in diameter after robotic-assisted laparoscopic radical prostatectomy. CASE PRESENTATION: A 56-year-old man was indicated a high prostate-specific antigen level of 37.8 ng/ml. Subsequent prostate biopsy revealed adenocarcinoma with a Gleason score of 4 + 4. The patient underwent robotic-assisted laparoscopic radical prostatectomy in Juntendo Hospital. Although his postoperative recovery was generally good, the patient complained of sudden nausea and acute abdominal pain. A contrast computed tomography scan showed an ileus due to a hernia occurring at the robotic right-hand port, the da Vinci Arm I port. We released incarceration under laparoscopic procedure. CONCLUSION: Since the port diameter is relatively small in robot-assisted surgery, port site hernias are expected to be rare. However, careful attention should be paid to the positional deviation of the remote center.
