Background:
So far there have been limited studies about the risk factors for benign small bowel obstruction (SBO) after colorectal cancer surgery. This study aimed to determine the factors affecting the development of benign SBO following curative resection in patients with rectal cancer.
Methods:
Patients (3472) receiving curative resection of rectal cancer at the Department of Colorectal Cancer, Tianjin Medical University Cancer Institute and Hospital, between January 2003 and December 2012 were retrospectively studied. The incidence of benign SBO and its risk factors were then determined.
Results:
The incidence of benign SBO was 7.3% (253/3472) in follow-up studies with an average time of 68 months. Further, 27% (68/253) of the patients received operative treatment because of the signs of strangulation or the lack of clinical improvement with conservative management. Open surgery and radiotherapy were defined as the risk factors for benign SBO after curative resection in patients with rectal cancer (P < 0.001).
Conclusion:
Open surgery plus radiotherapy led to an increased risk of benign SBO in rectal cancer patients receiving curative resection.
