Abstract

Purpose: Bowel dysfunction after rectal cancer surgery may significantly affect the quality of life. Our study aimed to estimate the incidence and characterize the low anterior resection syndrome (LARS).

Methods: Prospective evaluation of patients treated with anterior resection for rectal cancer at two hospitals followed for 12 months after ileostomy reversal. The assessment was performed at baseline, after neoadjuvant treatment, and 1 month, 6 months, and 12 months after bowel transit reconstruction using several scores (Bristol scale, LARS score, Memorial Sloan Kettering bowel function instrument, Fecal Incontinence Quality of Life, EORTC-QLQ30, and a visual analogue scale).

Results: Of 205 patients diagnosed with rectal cancer, 78 were followed for 12 months after the exclusion criteria. "Major LARS" at 1 month, 6 months, and 12 months was 55.6%, 47.3%, and 34.6%, respectively. At 12 months, patients experienced significantly less diarrhea, higher LARS score, more percentage of "major LARS," and worse MSK-BFI score compared to baseline. Regarding the quality of life at 12 months, 77.7% of patients with "major LARS" reported impact according to the anchor question of the LARS score; all FIQL subscales were significantly lower; the overall EORTC-QLQ30 score and the functional subscales significantly correlated with the LARS and the MSK-BFI scores.

Conclusions: Bowel dysfunction with an impact on the quality of life is common after rectal cancer surgery. The knowledge of the potential consequences of the treatments is essential to be able to provide patients with the best possible information.

Keywords: Bowel dysfunction; Low anterior resection syndrome; Quality of life; Rectal cancer.
