Direct cost measures included preoperative, intraoperative, and postoperative surgical expenses. Preoperative measures included diagnostic and consultation fees. Intraoperative metrics consisted of medical and nonmedical labor, anesthesia fees, and consumables (including amortized cost of equipment and sterilization). Postoperative surgical costs included the first postoperative follow-up visit and a postoperative visit at week 1 (POW1). Indirect costs were measured by the cost of travel and additional postoperative visits (any visits other than required for the first postoperative visit and POW1). Additional economic factors included total time spent travelling and total duration of travel.</p><p><strong>Results: </strong>The average costs were reduced by $375.22 CAD when performing ISBCS (p < 0.001), totaling to $1260.33 versus DSCBS's total cost of $1635.55.
