Objectives
Narrative objectives1 In general, obese patients are at increased surgical risk for perioperative complications. In recent years, a tendency towards obesity in patients with inflammatory bowel disease (IBD) has been reported. However, the relationship between obesity and the progress of IBD is not fully understood and there are limited data on the effect of obesity on perioperative outcomes in IBD patients. In obese patients undergoing surgery for ulcerative colitis (UC), there is a risk of increased operative time and hemorrhage. Another potential problem is difficulty in the pouch reaching the anus, owing to a thick intestinal membrane and a narrow pelvis in males. Whether the pouch will reach the anus cannot be predicted before surgery.
It has been reported recently that obesity does not impact perioperative or postoperative outcomes in patients with IBD. However, BMI does not necessarily reflect visceral obesity. Furthermore, IBD patients are at increased risk of central obesity as a result of the use of corticosteroids. Overall, there is a need for alternative measures to BMI for evaluating obesity. There have been reports that visceral obesity is a more accurate predictor of perioperative complications than BMI in patients with colon or gastric cancer. Regarding IBD, it has been reported that visceral obesity is a predictive factor of perioperative complications in Crohn's disease, but this has not been reported for UC. Therefore, our aim is to investigate whether visceral obesity predicts perioperative outcomes in patients with UC.
