Laparoscopic port site Richter's hernia after robot‐assisted radical prostatectomy

INTRODUCTION: Postoperative small bowel obstruction is a rare complication. One of its less frequent causes is port site hernia. We report a case of Richter's port site hernia in a patient who underwent robot‐assisted radical prostatectomy. CASE PRESENTATION: A 73‐year‐old man who underwent robot‐assisted radical prostatectomy noted acute abdominal pain and nausea on the 11th postoperative day. Computed tomography scans revealed dilated small bowel loops. Adhesive ileus was initially suspected, which was relieved with conservative management, including ileus tube insertion. However, his symptoms worsened. Thus, a laparotomy was performed. The camera port wound was reopened, and the repaired fascia and small intestine were found incarcerated into the peritoneal defects. These findings were consistent with Richter's hernia. CONCLUSION: Port site hernia was not detected on computed tomography scans. Patients presenting with small bowel obstruction following laparoscopic surgery should be evaluated for port site hernia, and surgical management should be considered.
