- Abstract
Objective Total mesorectal excision (TME) plus lateral pelvic lymph node (LPN) dissection (LPND) is a technically complex and challenging procedure with higher morbidity than TME alone. We aimed to investigate the risk factors for postoperative complications after TME + LPND, and the impact of complications on patient prognosis. Methods A total of 387 rectal cancer patients with clinical LPN metastasis (LPNM) who underwent TME + LPND at three institutions affiliated with the Chinese Lateral Node Collaborative Group were included. Logistic regression models were used to identify the risk factors for post-surgical complications, and the log-rank test was used to compare the prognosis. Severe complications were described as grade III-V. Results The incidence rates of overall complications and severe complications after TME + LPND were 15.2% (59/387) and 7.8% (30/387), respectively. Multivariate analysis showed that a duration of operation ≥260 min was an independent risk factor for both overall (odds ratio [OR] = 3.03, 95% confidence interval [CI] = 1.57–5.85, P = 0.001) and severe postoperative complications (OR = 2.67, 95% CI = 1.06–6.73, P = 0.037). The development of overall postoperative complications (P = 0.114) and severe postoperative complications (P = 0.298) had no significant impact on the overall survival. However, patients with overall complications (P = 0.015) or severe complications (P = 0.031) with a postoperative hospital stay >30 days had significantly an overall worse survival. Conclusion A surgical duration of ≥260 min is a significant risk factor for both overall and severe postoperative complications after TME + LPND for middle-low rectal cancer. Furthermore, the development of overall complications or severe complications that require a postoperative hospital stay >30 days significantly worsens the prognosis.
