An 8-mm trocar-site hernia at a drainage insertion site after a three-port robotic myomectomy: case report and review of literature.

Trocar site hernia is a rare, serious operation-related complication after robotic gynecologic surgery. Here, we present two 8-mm port-site hernia cases after three-port robotic myomectomy with a review of reported previous cases. In the first case, small bowel obstruction was found postoperatively due to herniation at the left mid-axillary line 8-mm trocar site. Small bowel herniation through the same site as the first case was found in the second case. Emergency exploration was performed in both cases by extending the left trocar site. There was no sign of bowel ischemia, and successful bowel reduction and hernia repair were done. Unlike previously reported cases, these cases occurred in a normal body mass index (BMI) patient (first case 20.28 kg/m, second case BMI 24.80 kg/m) and were pelvic drain insertion sites. These sites were the weak points of the abdominal muscle coverage. Therefore, the closure of 8-mm trocar sites should be considered.
