Because several sites of obstruction may be responsible, a systematic approach for selecting surgery has been developed. [199, 200] This is the Riley-Powell-Stanford surgical protocol designed in 1988. The protocol has 2 phases.

Patients who are not adequately treated with phase I surgery are offered phase II surgery.
