There were 158 cases of ulcerative colitis, which were computerized in Seou1 National University Hospital Medical Record Room, from January 1980 to February 1993. We reviewed 122 r,ases, which medical records were available, and treated at our hospital. The mast prevalent age groups of these patients were fourth and fifth decades and a male t.o femalc ratio was 1:2.1. Among l22 patients, 16 patients (13.19:) had undergone operations, and their most common indica tions of operations were medical intractability (12 cases). The initial procedures for 16 patients were 8 total proctocolectomies (including 6 Kock's pouche. and 2 Bronke ileostomies), a total colectomy with ileorectal anastomosis, a total colectomy with ileostomy, a total colectomy and rectal mucosectomy virith ileal pouch-anal anastomosis, a right hemicolectomy, a left hemicolectomy with transverse collostomy, a segmental resection of colon, a colostomy, a terminal ileostomy. After the initial procedures, l0 operations were performed additionally in 7 patient.;, 2 cases of total proctocolectomies (1 Korks pouch, 1 Brooke ileostomy), 1. case of rectal mucosectomy with ileal pouch-anal anastomosis, 4 cases of conversion to Brooke ileostomy, 3 cases of revision of nipplc valve, pouch, ileostomy. Total proctocolectomy with Kocks pouch was performed most commonly (in 7 patients), but 6 of them sufferred from complications, most of which were related to pouches and nipple valves. Nowadays, total colectomy, rectal mucosectomy and ileal pouch-anal anastomosis is regarded a. the standard operation for patients of ulcerative colitis, but we have performed this procedure in only two patients, ecently. Although their results are unknown due to short duraticn of follow up adoption of this procedure in the surgical management af alcerative colitis will be required.
