Closed-loop small bowel obstruction from lateral trocar site hernia following robotic sigmoid resection

Description

A 67-year-old man with medical history significant for hypertension and hyperlipidaemia was found on screening colonoscopy to have a large, polypoid adenomatous polyp of the distal descending colon not amenable to colonoscopic resection. He underwent a robotic sigmoid colon resection with primary anastomosis. Postoperatively the patient developed persistent abdominal distention, nausea and had no passage of flatus or bowel movements after 7 days which was initially attributed to ileus. Cross-sectional CT revealed a closed-loop small bowel obstruction secondary to an incarcerated hernia at the right lateral 8 mm robotic trocar site with surrounding subcutaneous emphysema (figure 1). On physical examination, there was no palpable bulge or overlying erythema along the previous incision. The patient was brought back to the operating room and underwent a diagnostic laparoscopy utilising the prior robotic incisions. On exploration, the incarcerated small bowel loop was easily reduced with gentle traction and appeared...
