Primary perineal wound closure following excision of the rectum.

Management of the perineal wound following rectal excision was assessed in 57 patients at the Toronto General Hospital; 40 had ulcerative colitis, 4 had Crohn's disease, 10 had carcinoma of the rectum, 2 had carcinoma of the anus and 1 had anal incontinence. The preferred technique was careful anatomical dissection with meticulous hemostasis, and primary skin closure with a laterally placed closed Hemovac suction system. Alternatively, wounds were packed and allowed to heal secondarily. Overall, the perineal wound healed primarily in 41 patients (72%). Primary closure was possible in 50 patients (88%); in 41 (82%) the wound healed without complication but in 9 (18%) the wound had to be opened because of hematoma and abscess (8 patients) or bleeding (1 patient). In 41 (91%) of the 44 patients with inflammatory bowel disease the perineal wound was closed primarily; 34 wounds (83%) healed without complication. In seven patients the perineal wound was packed at surgery because of bleeding (four), fecal spillage (two) or sepsis (one). Healing time averaged 6 months. These results indicate that primary closure is the optimal management of perineal wounds. Primary healing is achieved in a high proportion of patients and postoperative morbidity is decreased. Results are excellent in patients with inflammatory bowel disease as well as in those with carcinoma.
