ABSTRACT
PURPOSE:
To determine the effect of transanal total mesorectal excision (taTME) procedure on the postoperative bowel evacuation function of patients with low rectal cancer.METHODS:
Bowel evacuation function was investigated in 316 patients with rectal cancer after taTME in 18 hospitals in China. Low anterior resection syndrome (LARS) score, Wexner score, and EORTC QLQ-C30 were used for functional evaluation. The association between perioperative risk factors and LARS score was determined by univariate and multivariate analyses.RESULTS:
The prevalence rate of no LARS, minor LARS, and major LARS in patients after taTME was 39.9%, 28.2%, and 31.9%, respectively. The two most frequently reported symptoms of LARS after taTME were bowel clustering (72.8%) and fecal urgency (63.3%). Patients with major LARS had significantly higher Wexner score and worse global health status and financial difficulties according to the EORTC QLQ-C30 questionnaire than those without major LARS. Preoperative chemoradiotherapy was an independent risk factor of major LARS occurrence after taTME (OR 3.503, P = 0.044); existing preoperative constipation (OR 0.082, P = 0.040) and manual anastomosis (OR 4.536, P = 0.021) were favorable factors affecting bowel evacuatory function within 12 months after taTME, but for patients whose follow-up time was longer than 12 months, postoperative chemoradiotherapy (OR 8.790, P = 0.001) and defunctioning stoma (OR 3.962, P = 0.010) were independent risk factors.CONCLUSIONS:
The bowel evacuation function after taTME is acceptable. Perioperative chemoradiotherapy, anastomotic method, and preoperative constipation are factors associated with bowel dysfunction after taTME.Palavras-chave
