Flow diagram of the selection of patients in each cohort. Cohort 1 comprised all patients who underwent EUS for PCD and was assembled to describe our experience using EUS to guide the management of pediatric patients with PCD. Cohort 2 comprised all patients who underwent seton placement and was assembled to determine if using EUS to monitor healing around a seton improves outcome. 1EUS-directed Care – subjects underwent at least one EUS following seton placement to monitor healing; 2Standard care – subjects followed by physical exam only following seton placement.
