궤양성 대장염 환자에서 시행되는 회장낭 수술에 대한 이견
유창식 대한대장항문학회 2009 Annals of Coloproctolgy Vol.25 No.3
Restorative proctocolectomy (RPC) has become a standard procedure over 30 yr in patients with ulcerative colitis and familial adenomatous polyposis. However, there are several controversies in surgical method and strategy. From oncological point of view, mucosal proctectomy and hand-sewn ileal pouch anal anastomosis has advantage because of relatively complete removal of columnar epithelium. However, long-term follow-up results after stapled anastomosis revealed extremely low incidence of dysplasia in the anal transitional zone (ATZ). Furthermore, recent publication of 26 cancer occurrence after RPC showed more prevalence in mucosectomy group. Risk factors of dysplasia after RPC are supervening cancer or dysplasia on the proximal colon, long duration of symptom, and history of primary sclerosing cholangitis. Preservation of ATZ by stapled anastomosis may have functional superiority, which is supported by some manometric and functional studies. However, two randomized controlled trials showed no difference between the groups. Although there are some surgeons who advocate one stage RPC, majority of centers prefer two stage RPC with ileostomy. According to meta-analysis one stage RPC revealed 2-3 times frequent anastomotic leakage or pelvic sepsis. Five to ten percent of ulcerative colitis has some pathologic characteristics of Crohn’s disease, which is classified as indeterminate colitis (IC). Long-term results of RPC in patients with IC revealed similar results with ulcerative colitis and superior to Crohn’s disease. So RPC may be justified in patients with IC. Conclusively, RPC should be tailored according to clinicopathologic details and operative findings.

Purpose: The aim of this study was to evaluate the efficacy of using a Hyaluronate (HA) bioresorbable membrane (SeprafilmTM, Genzyme Corp., Cambridge, MA) to prevent adhesion after rectal cancer surgery. Methods: We recruited 362 rectal cancer patients who underwent a curative resection between April 2001 and December 2002. We excluded patients with a previous operation history, a stoma procedure, a multivisceral resection, an extended lymphadenectomy, a total colectomy, or a pouch procedure. An adhesive ileus was defined as a symptomatic, radiological intestinal obstruction without evidence of recurrence. Results: We placed the HA membrane under the midline incision in 153 patients. There was no difference between the groups regarding demographic findings and clinicopathological findings, including locations of the tumors, surgery performed, AJCC stage, and adjuvant treatment. While only 1 (0.7%) patient of the HA group experienced an adhesive ileus, 13 (6.2%) cases of adhesion were identified in the control group (P=0.008). Every patient, except 1 in the control group, underwent conservative management. Conclusions: A Hyaluronate membrane may be effective in preventing an adhesive ileus after rectal cancer surgery. However, a prospective, randomized, double-blind study is needed.
