Risk Factor Analysis of Postoperative Intestinal Obstruction in Elderly Patients with Colorectal Cancer

Abstract

Objective To investigate the risk factor of postoperative intestinal obstruction in elderly patients with colorectal cancer. Methods A retrospective analysis was conducted on 300 elderly patients who underwent radical resection for colorectal cancer admitted to Jiangsu Cancer Hospital from January 2021 to February 2024. Patients were divided into an occurrence group (40 cases) and a non occurrence group (260 cases) based on whether intestinal obstruction occurred within 30 days after surgery. Clinical data were collected and compared between the two groups. Multivariate logistic regression analysis model was performed to identify risk factors for postoperative intestinal obstruction. Results The differences in age, gender, smoking history, tumor location, TNM staging, and abdominal surgery history between the two groups were statistically significant(P<0.05). Multivariate logistic regression analysis revealed that age ≥70 years, male gender, rectal tumor, and TNM stage Ⅲ were independent risk factors for the development of intestinal obstruction within 30 days postoperatively in elderly colorectal cancer patients(P<0.05). Conclusion Elderly patients with colorectal cancer aged ≥ 70 years, male, rectal tumors, TNM stages Ⅲ have a higher risk of developing intestinal obstruction within 30 days after surgery, and clinical attention should be paid.
