Abstract [en]

BACKGROUND: Fecal incontinence is a rare but well-known adverse effect of hemorrhoidectomy. OBJECTIVE: The objective of this study was to identify possible reasons for incontinence after hemorrhoidectomy. DESIGN: We conducted a retrospective comparative study. SETTINGS: The study was performed in 1 university hospital and 1 general district hospital serving 2 counties in central Sweden. PATIENTS: In a cohort of 418 patients with consecutive Milligan hemorrhoidectomies, 40 reported fecal incontinence that was attributed to surgery. Of these, 19 patients agreed to participate. Fifteen age- and sex-matched patients from the same cohort who were operated on, but without symptoms of incontinence, were also studied, as was a third reference group of 19 age- and sex-matched persons serving as a population-based control group. INTERVENTION: All of the participants answered a bowel function questionnaire and underwent clinical evaluation, including rectoscopy, anal manometry, saline infusion test, and endoanal ultrasound. MAIN OUTCOME MEASURES: We evaluated anal resting and squeeze pressures, sphincter defects, and continence function. RESULTS: The symptomatic patients had higher incontinence scores than the control groups (p = 0.00002). The mean resting pressure at the high-pressure zone was also reduced in this group (p = 0.047). External sphincter injuries were detected in 4 (20%) of 19 subjects compared with none in the control group (p = 0.11). Saline infusion test in the patients reporting incontinence showed reduced ability to hold liquids compared with healthy controls (p = 0.004). LIMITATIONS: This study was limited by selection bias and limited numbers in the groups. CONCLUSIONS: In the group of patients reporting incontinence after hemorrhoidectomy, there was a proportion with sphincter defects and impaired sphincter function. These results indicate a need for cautious patient selection and improved or alternative surgical techniques.
