Analysis of short-term outcome indicators and risk factors for postoperative complications in patients with sigmoid colon cancer by transumbilical single-port plus one port laparoscopy

This study aimed to compare the efficacy of Single-Port plus One Port Laparoscopy (SILS + 1) with Conventional Multi-Port Laparoscopic Surgery (CLS) and investigate risk factors associated with postoperative complications in patients with sigmoid colon cancer undergoing laparoscopy. Male patients with sigmoid colon cancer treated at our hospital were selected and evenly distributed into the CLS and SILS + 1 groups and further categorized into complication and non-complication groups based on their complications status within 30 days post-surgery. Compared to the CLS group, the SILS+ 1 group had significantly shorter incision length, greater distance to the lower edge of the tumor and shorter time to first postoperative ambulation (p < 0.05). A total of 20 cases (16.67%) developed complications within 30 days post-surgery, and among them, 8 (13.33%) were in the SILS + 1 group and 12 (20.00%) in the CLS group (p = 0.327). Logistic multivariable regression analysis showed that age (p = 0.028; Odds Ratio (OR) = 1.028; 95% confidence interval (CI): 1.003–1.054), body mass index (BMI)(p = 0.002; OR = 1.950; 95% CI: 1.248–2.961) and operation time (p < 0.001; OR = 1.067; 95% CI: 1.030–1.106) were independent risk factors for complication occurrence within 30 days post-surgery, and at 2-year follow-up, there was no significant difference in overall survival between both groups (p > 0.05). In conclusion, age, BMI and duration of surgery were identified as independent risk factors for postoperative complications in male sigmoid colon cancer patients, among whom SILS + 1 was found to reduce postoperative discomfort and accelerate recovery compared to CLS while maintaining surgical efficacy.
