Is the 8-mm robotic port safe? A case of trocar site hernia after robotic cholecystectomy using the da Vinci Xi system.

With the increase in the frequency of robotic surgery, complications have also increased, including trocar site hernias, which rarely occur at the 8-mm port site after robotic cholecystectomy using the da Vinci Xi system. A 37-year-old woman was diagnosed with cholecystitis on abdominal sonography. She underwent robotic cholecystectomy using a bikini-line incision. However, after postoperative day 2, she presented to the emergency room with small bowel obstruction secondary to a herniated bowel loop through the left 8-mm port site. After failure to resolve the ileus, the patient underwent emergency surgery, and bowel resection and anastomosis of the ischemic area were performed. After surgery, the patient was discharged without complications. Although hernias develop less commonly at 8-mm robotic port sites, surgeons should carefully close the ports, especially in cases with large fascial defects or a high risk of herniation.
