Introduction: This prospective, observational study evaluated transanal dearterialization (THD) efficacy and safety in grade 2-4 hemorrhoids (HD).
Methods: THD was performed under sedation-locoregional anesthesia in 402 outpatients. Patients had follow-up evaluation 3 days, 2 weeks, 1, 6 and 12 months postoperatively. Postoperative complications and recurrence of symptoms at 12 months were analyzed. The relationship between the learning curve and the number of postoperative complications was studied.
Results: Mean patient age was 46.4 (range 20-85) years. A total of 268 patients (66.6%) were male. Sixteen patients (4.0%) had grade 2 HD, 210 (52.2%) had grade 3 and 176 (43.8%) had grade 4 HD. Surgery lasted 23 (17-34) min. A total of 67 patients had complications: bleeding in 10 patients (2.5%), hemorrhoidal thromboses in 10 (2.5%), perianal fistulas in 5 (1.2%), fissures in 14 (3.5%), urinary retention in 3 (0.8%), residual prolapse in 19 (4.7%), severe anal pain in 3 (0.8%), and perianal abscess in 3 patients (0.8%). Recurrent HD occurred in 6.3% (1/16) of grade 2 HD patients, 5.8% (12/210) of grade 3 patients and 9.7% (17/176) of grade 4 patients. Twelve months after THD, bleeding was controlled in 363 patients (90.5%), prolapse was controlled in 391 (97.3%) and pain markedly improved in 390 patients (97%).
Conclusion: THD appears safe and effective for grade 2-4 HD, and the number of complications decreased with increasing surgeon experience. THD advantages include mild pain, fast recovery, early return to daily activities and low incidence of complications.
