Abstract

BACKGROUND: With decreasing indication for abdominoperineal resection and an increase in sphincter preserving surgery, there is a growing population of patients who suffer from low anterior resection syndrome (LARS). The aim of this study is to use the LARS score to determine the prevalence of LARS at a regional centre in Australia and determine the effect of short- and long-course neoadjuvant therapy, anastomotic technique and interval from surgery will also be assessed.

METHODS: Patients who had undergone an anterior resection (high, low or ultralow) at a regional centre over an 11-year period were identified. Eligible patients were contacted to complete a LARS score questionnaire. Results were analysed to determine the rate of major LARS and possible causative roles of certain patient and treatment-related variables.

RESULTS: A total of 64 of 76 patients (84%) returned completed questionnaires. The prevalence of major LARS was 37.5%. Short-course neoadjuvant therapy appeared to be more likely to be associated with major LARS compared to long course (odds ratio (OR) = 2.4, 95% confidence interval (CI) 0.37-15.3, P = 0.35); however, this did not reach statistical significance. Rates of major LARS appear to decrease slowly over time and J-pouch colonic anastomosis appears to be slightly protective against major LARS (OR = 0.7, 95% CI 0.12-3.9, P = 0.70); however, neither results were statistically significant.

CONCLUSION: The rate of major LARS at this regional centre is 37.5%. Larger prospective multicentre studies are required to determine impact of variables such as type of neoadjuvant therapy, anastomotic techniques and progression of LARS over time.
