Impact of office-based surgery for hemorrhoids on clinical outcomes and institutional costs: a prospective controlled study

Aim: Transanal hemorrhoidal artery ligation with mucopexy (THAL-m) is a treatment option for symptomatic hemorrhoidal disease (HD). Open hemorrhoidectomy (OH) has stood the test of time in terms of radical cure for HD. Both techniques can be performed under local anesthesia. The aim of this study was to determine the impact on postoperative outcome and cost-effectiveness of performing these techniques in ambulatory setting in an Italian academic centre. Method: A prospective series of grade II /III HD. 100 consecutive patients undergoing ambulatory surgical treatment of hemorrhoids in 2015–2017 (group A) were compared to 100 patients operated at the same institution in the same period (Group H) by hospitalization. The primary outcome was sick leave used as a proxy of clinical outcome. Secondary outcomes included postoperative complications, cost-effectiveness, and patient satisfaction. Results: Sick leave was significantly reduced in Group A patients (8 days versus 15) with no increase in postoperative complications, and patient satisfaction was high. Total mean direct costs per patient were significantly lower in office-based setting versus the hospital stay group (431 euros versus 1320). Conclusion: Implementing ambulatory surgery for hemorrhoids is feasible, efficient, safe, and cost-effective but correct selection of patients is necessary.
