ABSTRACT
PURPOSE: To evaluate the efficacy of a modified small bowel follow-through (SBFT) and to optimize this technique. MATERIALS AND METHODS: Ninety-nine subjects without small bowel pathology underwent modified SBFT using oral administration of methylcellulose after taking 100ml of 120% or 100, 150, or 200ml of 70% barium. Thirty-three and 39 normal subjects undergoing enteroclysis or conventional SBFT, respectively, were also evaluated for comparison of image qualities and transit time. RESULTS: Enteroclysis was the most successful ofthree types of small bowel examination for obtaining the best quality of bowel transradiency and distension. Modified SBFT was, however much superior to the conventional series for obtaining good bowel transradiency and rapid transity time (mean, 37-49 minutes). The use of 150ml of 70% barium was better than the other three modified techniques in achieving good bowel transradiency, rapid transit time, and less flocculation. CONCLUSION: Our modified SBFT is a simple and safe method for easily improving bowel transradiency and transit time.
