Cost calculation
During this trial, we considered direct costs, including both medical and non-medical for all patients who underwent OH in the two groups. The materials used during and after open hemorrhoidectomy in both groups such as surgical blades, gloves, drugs among others, and the anesthetic fees were considered as medical direct costs. The non-medical direct costs were those not directly accountable to patients such as: administration, hospital stay, nursing care, files, among others. A total of 58 envelopes were obtained, half of the envelopes contained a chit with letter A for LA and a chit with letter B for saddle block. All financial data are expressed in US dollars (1 US$ = 3729.50 Ugandan shillings) (updated on 22nd June 2022).
