BACKGROUND: Aluminum potassium sulfate and tannic acid sclerotherapy for hemorrhoids produced almost the same effects as excisional hemorrhoidectomy. However, its long-term effectiveness remains unknown.
OBJECTIVE:The purpose of this study was to investigate the long-term results of sclerotherapy using aluminum potassium sulfate and tannic acid for treating prolapsed hemorrhoids.DESIGN: This was a retrospective review of a singleinstitution experience.
SETTINGS:This study was conducted within a coloproctology unit at a community-based hospital.
PATIENTS:In total, 1180 patients with grade II to IV hemorrhoids treated with injection sclerotherapy were enrolled.
MAIN OUTCOME MEASURES:Efficacy measures included cumulative recurrence rates and postoperative complications.
RESULTS:Recurrence rates at 3, 6, and 9 years were 7.4%, 27.2%, and 47.5%. Postoperative complications included fever ≥38°C in 16 (1.4%) patients, rectal ulcer in 10 (0.9%) patients, rectal stricture in 5 (0.4%) patients, and perianal abscess in 4 (0.3%) patients.
LIMITATIONS:This was a retrospective, nonrandomized, single-center study. In addition, office visits after 3 years were optional and the number of follow-ups steadily decreased.CONCLUSIONS: Sclerotherapy using aluminum potassium sulfate and tannic acid offers reasonable longterm results and is associated with low complication rates. Therefore, it seems to be an attractive alternative for patients with prolapsed hemorrhoids. See Video Abstract at http://links.lww.com/DCR/B733.
