A 13-year-old thin Arabian gelding presented to Cornell University Large Animal Hospital with a history of colic unresponsive to medical management. At surgery, the patient had a large colon volvulus with cecal involvement and secondary small intestinal distension. Six days after surgery, serosanguinous drainage was noted dripping from the mid-cranial aspect of the incision. Ultrasound showed a defect in the body wall that appeared to be continuous with the peritoneal space at the site of drainage. A belly band was placed at that time. Eight days after surgery, the incisional drainage and peri-incisional defects had worsened and an additional belly band was applied. The patient stabilized and was slowly introduced to feed before being discharged to the care of his owner 18 days postoperatively.
