Partial colonic obstruction following ovariohysterectomy: A report of three cases

Partial extramural obstruction of the descending colon was diagnosed in two dogs and a cat as a complication of elective ovariohysterectomy, In each case, the obstruction was caused by fibrous tissue that encircled or crossed the descending colon, severely restricting the organ's normal mobility and luminal diameter. Clinical signs secondary to obstipation were observed in two cases, five weeks and 27 months after elective ovariohysterectomy, In one dog without clinical signs, the adhesion was an incidental finding during a laparotomy performed nine years after the ovariohysterectomy, The fibrous adhesions were removed surgically in all three cases without additional complications.
