A 46-year-old male underwent a left laparoscopic radical nephrectomy for a cT1b renal cell carcinoma. Intra-operatively, a rent in the descending mesocolon was made during bowel mobilization but was not closed. The remainder of the procedure was uneventful and the patient was discharged home on post-operative day 1 after passing flatus. Subsequently, the patient presented to the emergency room 4 days later with complaints of sudden onset sharp abdominal pain and nausea. A non-contrast CT scan was obtained (figure 1, below).
