Abstract
INTRODUCTION: bowel dysfunction is the most common and disabling complication after anterior rectal resection (ARR) for cancer. We aimed to evaluate these complications in a cohort of Cameroonian patients, using the low anterior rectal syndrome (LARS) score. METHODS: we conducted a descriptive and analytical cross-sectional study, in two university hospitals of Yaoundé (Cameroon). Prospectively, we collected the records of all patients aged at least 18 years who had an ARR indicated for rectal cancer from January 2015 to March 2018. Alive patients among them were subsequently received in consultation at 1 and 3 years after surgery, for short and long-term assessment of their digestive function using the LARS score. RESULTS: during the study period, 28 patients underwent anterior rectal resection for rectal cancers. Short-term bowel function was evaluated in 23 patients. Their mean age was 48.42 ± 12.2 years and 14 were males. LARS was present in 10 of them (43.47%) and classified as "minor" in the majority of cases (n=6). The commonest bowel dysfunction at this term was splitting of stool (56.53%). Long-term digestive function was evaluated in 11 patients; LARS was found in 3 of them (27,27%) and classified as minor in all cases. Perfect continence was significantly improved (p=0.003) in the long term compared to the short-term status. Continence (p=0.049) and urgency (p=0.048) were better in patients who had a low colorectal anastomosis compared to those who had a colo supra-anal anastomosis. CONCLUSION: after ARR for cancer, there is a high prevalence of LARS in the short term with an improvement in the long term.
