 note = {Objectives：The surgical method and the timing of surgical intervention for refractory ulcerative colitis（UC）remain controversial. Several studies have reported that the nutritional indicators are useful for predicting of postoperative complications. This study aimed to clarify the relationship between nutritional status and outcome of surgery for UC.
Methods：This was a single-institution, retrospective study of patients with UC who underwent surgery between 2006 and 2019, excluding those who underwent emergency surgery. The Controlling Nutritional（CONUT）score and Onodera’s prognostic nutrition index（OPNI）were used as indicators of nutritional status. The moderate cut-off point was determined using the receiver operating characteristic curve.
Results：A total of 51 UC patients underwent surgery between 2006 and 2019. Thirty-five UC patients were included in this study after excluding those who underwent surgery for emergency indications such as perforation, toxic megacolon. 57％（n＝20）of the patients received three-stage surgery. Postoperative complications（Clavien-Dindo classification＞II）occurred in 40％（n＝14）of patients. The prevalence of surgical site infection was 12％. The areas under the curve for the frequency of surgical site infection were 0.72 and 0.75 for CONUT and OPNI, respectively. The cut-off value for CONUT was 8.00（sensitivity：84％, specificity：50％）and OPNI was 46.5（sensitivity：44.8％, specificity：100％）. The malnutrition cohort as identified using CONUT and OPNI had a higher rate of postoperative complications than non-malnutritionl cohort（p＝0.04, p＝0.01）.
Conclusion：Nutritional status indicators are useful for determining the operative method for the treatment of UC.},
