BACKGROUND: Patients with rectal cancer are usually at advanced stage with or beyond serosa invasion in China. Severe complications after laparoscopic rectal surgery leads to prolonged hospitalization and high medical cost. This study aimed to explore risk factors for severe complications after laparoscopic surgery of T3 or T4 rectal cancer.
MATERIAL AND METHODS: A total of 287 patients diagnosed with T3 or T4 rectal cancer were enrolled from the Department of Gastrointestinal Surgery of Anhui Provincial Hospital from February 2012 to February 2017. Univariate analysis and multivariable logistic regression model were used to analyze the risk factors for severe complications (Clavien-Dindo grade ≥III) after laparoscopic surgery.
RESULTS: Eighteen patients (6.25%) had severe complications; 15 patients were categorized as Clavien-Dindo grade III, and 3 patients were categorized as Clavien-Dindo grade IV. Univariate analysis showed that male gender, high preoperative white blood cells (WBC), diabetes mellitus, pulmonary dysfunction, and tumor distance from anus were associated with increased risk of severe complications after laparoscopic surgery for rectal cancer. Multivariate analysis showed that preoperative WBC ≥6.9×10⁹/L (OR=5.54 (1.58-19.45), P=0.008), diabetes mellitus (OR=13.07 (3.31-51.67), P=0.000) and pulmonary dysfunction (OR=7.75 (1.69-35.63), P=0.008) were independent risk factors for postoperative severe complications.
CONCLUSIONS: Preoperative high white blood cells, diabetes mellitus and pulmonary dysfunction were independent risk factors for severe complications after laparoscopic surgery for T3 or T4 rectal cancer.
