The purpose of this paper is to describe our experience with a new technique of colonic manometry catheter placement using fluoroscopic guidance. Between 2000 and 2004, 44 colonic manometry catheters were placed with primary fluoroscopic guidance in 38 patients (25 males; median age, 7 years; range, 0.4–31 years) with severe defecation disorders. Fourteen colonoscopic placements were reviewed to compare the different procedures. Manometry catheters were inserted through the rectum (16 patients), cecostomy (9), ileostomy (2), and colostomy (17). Placements through diverted colons were successful in 24 of 28 (86%). Insertion through the rectum was successful in 10 of 16 (63%) fluoroscopic-guided placements vs. 12 of 14 (86%) colonoscopic placements (P=0.23). Significantly longer fluoroscopic exposure was required for fluoroscopic compared to colonoscopic placement (P=0.004).
In conclusion, placement of colonic manometry catheters with primary fluoroscopic guidance is feasible in children. An important disadvantage of the fluoroscopic methodology is the prolonged fluoroscopic exposure time.
