A 3-year-old boy has partial-thickness rectal prolapse intermittently for the last 6 months. His parents need to manually reduce it every other week. He passes a hard stool every 2 to 3 days. There is no history of greasy stools or failure to thrive. The most appropriate next step is:
A Sweat chloride test
B Pelvic floor therapy
C Laxative therapy
D Laparoscopic rectopexy
