Surgical complications in bariatric procedures occur despite all efforts to minimize their incidence. This chapter examines the costs and expenses associated with four complications: bleeding, stricture, staple-line leak, and internal hernia. In addition, it defines the relationship between the expense of techniques designed to reduce the incidence of complications and the cost of caring for the patient who sustains a complication. Last, it explores the medicolegal and financial implications of any surgical complication in the changing healthcare landscape of the future. Through a better understanding these issues, surgeons should be able to tailor their practice by determining the cost/benefit and “value” of interventions used to prevent or treat complications.
