Mid-term outcome of a novel nonexcisional technique using aluminum potassium sulfate and tannic acid sclerotherapy with mucopexy on patients with grade III hemorrhoids.

BACKGROUND

Aluminum potassium sulfate and tannic acid (ALTA) is an effective sclerosing agent for the treatment of internal hemorrhoids. ALTA therapy with rectal mucopexy (AM) is a new approach for treating hemorrhoidal prolapse. This study investigated the midterm outcomes of AM surgery in patients with hemorrhoids.

METHODS

Patients with grade III hemorrhoids who underwent AM surgery were enrolled in this retrospective analysis of prospectively collected data from a single institution. Cumulative success rates, postoperative symptoms, including pain scores, analgesic requirements, and postoperative complications, and patient satisfaction were assessed.

RESULTS

The median number of ALTA injection procedures was 3 (range 1-4), and the median total injection dose was 19 mL (range 7-32 mL). The median number of mucopexy procedures was 2 (range 1-4). The median postoperative pain score (0 = no pain at all, 10 = worst pain imaginable) at rest or during defecation were ≤2. The total dose of analgesics administered during the first two weeks after surgery was 1 (range 0-25). Six patients (5.3%) showed postoperative complications: five showed Clavien-Dindo (C-D) grade I and one showed C-D grade IIIa complications. Cumulative success rates at one, three, and five years were 96.5%, 85.3%, and 85.3%, respectively. Patient satisfaction scores, which were assessed using a 10-point scale, were ≥9 at each postoperative year.

CONCLUSIONS

AM surgery is an effective non-excisional surgery with satisfactory mid-term results for grade III hemorrhoids, and is associated with lower complication rates, postoperative analgesic requirements, and higher patient satisfaction.
