Aim The aim of this work was to review our institutional series of patients treated with sacral neuromodulation (SNM) for low anterior resection syndrome (LARS) and evaluate possible factors associated with therapeutic success. Method Twenty‐five patients were treated with SNM for LARS between 2008 and 2019. SNM was performed as per our institutional protocol. Patients were evaluated with Wexner and LARS scores before and after SNM treatment. A visual analogue scale (1–10) was used to evaluate overall patient satisfaction with SNM. Results There were significant differences between the mean LARS score values before (37.82) and after (29) SNM therapy ( P < 0.004). The mean Wexner score was higher (16.24) before SNM treatment than afterwards (11.13) ( P < 0.004). There was a direct relationship between the height of anastomosis and LARS score ( P = 0.035): there were big changes in LARS scoring (pre‐/post‐SNM therapy) in patients with higher anastomoses, and vice versa. Patients who received radiotherapy scored lower in mean satisfaction (6.38) than patients without previous radiotherapy (8.22) ( P = 0.008). There was an important positive association between Wexner score and patient satisfaction ( P = 0.001): relevant changes in Wexner scoring after SNM therapy were associated with high patient satisfaction, and vice versa. Conclusion Our study showed a relationship between changes in Wexner and LARS scores before and after SNM and overall patient satisfaction with SNM therapy. These findings also suggest patients with previous radiotherapy may have worse results with SNM (based on lower overall satisfaction), and that higher anastomoses have a greater impact on the post‐SNM LARS score.
