Incidence and risk factors for incisional hernia after open surgery for colorectal cancer.

To confirm the incidence and risk factors of incisional hernia after colorectal cancer surgery, we analyzed the clinical data including the surveillance computed tomography (CT) examination.One hundred sixty seven patients with open abdominal surgery for colorectal cancer were analyzed retrospectively.Incisional hernia was recognized in 27 cases (16.2%), and occurred at median 7 (1-21) months after surgery. Multivariate analysis showed the risk factors for incisional hernia were female (p=0.0014), distal colon and rectal cancer (p=0.0038), high body mass index (p=0.0055) and lower serum albumin (p=0.0081).Obesity, lower median incision and malnutrition might seem to relate to the incisional hernia after colorectal cancer surgery.
