A 61-year-old man undergoes a laparotomy for bowel obstruction. On postoperative day 2, while walking in the hallway he experiences a sudden sharp pain and tearing sensation in his lower abdomen. Physical examination of the abdomen reveals separated wound margins with a tiny gaping area and splitting of the sutures in the lower half of the incision. His vital measurements indicate a blood pressure of 130/80 mmHg, and a heart rate of 96 beats per minute.
