INTRODUCTION: The inadvertent removal of smooth muscle during the use of stapled hemorrhoidectomy had raised concerns about its effects on postoperative anorectal function. We correlated the amount of smooth muscle removed with anorectal function in the early postoperative period. METHODS: Patients were assessed preoperatively with an Eypasch quality-of-life questionnaire and underwent anorectal manometry and physiology testing. This was followed by a similar examination at three months postoperatively. Patients were operated on by a single surgeon and the excised anorectal mucosa was sent for histologic examination. The amount of smooth muscle excised was expressed semiquantitatively as a percentage of the total tissue removed. RESULTS: Sixty-eight patients (33 males) were recruited prospectively, with median age of 44 years. Six patients were lost to follow-up. Removal of anal transitional zone did not increase the incidence of incontinence. Both median preoperative and postoperative continence scores were good. Only one patient had incontinence to gas as a result of the operation. Median preoperative and postoperative quality-of-life scores were 114 and 131, respectively, out of a total of 144, the higher postoperative scores showing an improvement. Correlation of quality-of-life scores and mean resting anal pressures with percentage of smooth muscle removed did not show any statistical significance. CONCLUSIONS: Some smooth muscle will invariably be excised in stapled hemorrhoidectomy but the amount of smooth muscle removed did not significantly affect the continence score, quality of life, or mean anal resting pressure after stapled hemorrhoidectomy. It remains a safe and preferred procedure for the treatment of hemorrhoids.
