Table 1 Risk factors of obstructive complication of diverting ileostomy

Risk factors
Patient characteristics
Young age (less than 16 yr old)[11]
Low body mass index (less than 21 kg/m2)[11]
Thick subcutaneous fat at the stoma marking site (20 mm or more) [16]

Long distance between the superior mesenteric artery root and the bottom of the external anal sphincter (height-adjusted, 191 mm/m)[19]
Disease
Ulcerative colitis (compared with colorectal cancer)[15]
Surgical factors
Laparoscopic surgery (compared with open surgery)[18,22]
Rotation of stoma limb (180-degree rotation, the oral limb situated on the caudal side)[21]
Ileal-pouch anal anastomosis (compared with low anterior resection or intersphincteric resection)[12]
Two-stage surgery for ulcerative colitis[20]
Short distance from the ileal pouch to the stoma site (< 30 cm)[12,18]
Stoma functions
