Surgery for Ulcerative Colitis - A Comparative Retrospective Study -

The records of patients with ulcerative colitis (UC) who underwent operation at our hospitals between 1973 and 1995 were reviewed. The clinical course of the disease was the chronic relapsing-remitting type in seven, chronic continuous type in four, acute attack of the relapsing-remitting type in six, and fulminant colitis (toxic megacolon) in two patients. The most common indication for surgery was a condition refractory to conservative therapy. Four patients with massive bleeding, perforation and toxic megacolon underwent emergency operation. The surgical procedures performed were ileoanal anastomosis (IAA) in four, ileoanal canal anastomosis (IACA) in one, ileorectal anastomosis (IRA) in five, proctocolectomy and permanent ileostomy (PCI) in four, and colectomy in five patients. The mortality rate was 5.2%. During follow-up, drug therapy with sulfasalazine (salazosulfapyridine) in colectomy or IRA patients was necessary to control inflammation in the remaining rectal mucosa. One patient with segmental colectomy for severe colitis required removal of the remaining colon 1 year later. Three out of four patients undergoing total proctocolectomy and IAA had a good postoperative course with an average of six bowel movements in 24 hours, but one patient with a long rectal cuff was returned to a PCI because of a cuff abscess. The PCEEA instrument was sufficient to perform IAA and IACA. Carcinoma in the remnant rectum occurred in one patient 20 years after Hartmann\u27s procedure. In conclusion, total proctocolectomy, which has the advantage of removing all diseased mucosa with its potential for inflammation, dysplasia, and carcinoma, may be preferable for extensive long-standing UC
