This study confirms high rates of AL following ISA and IRA. In particular, a synchronous procedure with colectomy and ISA/IRA carries a high risk of AL.

Background This population‐based cohort study aimed to evaluate occurrence of low anterior resection syndrome (LARS) and correlate this to health‐related quality of life in patients who had undergone segmental colonic resection for colonic cancer in the Stockholm–Gotland region. The hypothesis was that there is a difference in occurrence of LARS depending on whether a right‐ or a left‐sided resection was performed. Methods Patients who underwent segmental colonic resection for colonic cancer stages I–III in the Stockholm–Gotland region in 2013–2015 received EORTC QLQ‐C30, QLQ‐CR29 and LARS score questionnaires 1 year after surgery. Clinical patient and tumour data were collected from the Swedish ColoRectal Cancer Registry. Patient‐reported outcome measures were analysed in relation to type of colonic resection. Results Questionnaires were sent to 866 patients and complete responses were provided by 517 (59·7 per cent). After right‐sided resection 20·6 per cent reported major LARS. After left‐sided resection the proportion with major LARS was 15·6 per cent. The odds ratio (OR) for major LARS after right‐sided resection was 1·45 (95 per cent c.i. 1·02 to 2·06; P = 0·037) compared with left‐sided resection. After adjustment for age and sex, an increase in the risk of major LARS after right‐ versus left‐sided resection remained (OR 1·48, 1·03 to 2·13; P = 0·035). Major LARS correlated with impaired quality of life. Conclusion Major LARS was more frequent after right‐sided than following left‐sided colonic resection. Major LARS reflected impaired quality of life.
