Objective To investigate the risk factors of intestinal obstruction after radical surgery of cervical cancer.

Methods We retrospectively analyze the clinical data of 2585 cervical cancer patients underwent radical surgery in Tumor Hospital of Yunnan Province from June 2012 to June 2017. Among them, 149 patients had intestinal obstruction. We comparatively analyzed the risk factors for intestinal obstruction.

Results The incidence of intestinal obstruction was related to age, duration of operation, postoperative serum potassium level, postoperative fasting time, the history of preoperative pelvic operation, BMI, operation method, postoperative infection and postoperative peritoneal effusion (P < 0.05). The history of pelvic operation, long postoperative fasting time, low postoperative blood potassium level and long operation time were independent risk factors. However, there was no statistically significant difference between the two groups in blood loss, hemoglobin level or intraoperative blood transfusion(P > 0.05).

Conclusion Shortening the operation time, encouraging patients to eat early and maintaining the postoperative blood potassium level after operation are the effective measures to prevent the intestinal obstruction after radical surgery of cervical cancer.
