Purpose: The objective of this study is to evaluate the anorectal function from the viewpoint of fecoflowmetry in postoperative patients with Hirschsprung's disease (HD). Methods: This study evaluated 23 long-term follow-up patients who had undergone a radical operation for HD. Their mean age was 11 years. The types of HD included rectosigmoid colon type, 18 cases, and entire colon type, 5 cases. An anorectal manometric study was performed before fecoflowmetry. After normal saline solution was administrated as an imitation stool into the rectal cavity under pressure monitoring, the patients defecated on a fecoflowmeter. After discussing the maximum defecation flow (Flow-max), fecoflow pattern (FFP), tolerance rate (TR), anal canal pressure (AP), and Kelly's clinical scores (Kelly-Scores), the significant parameters were identified to elucidate the anorectal activity. Results: (1) A close relationship was observed between the FFP and Kelly-Scores (P = .0027). (2) Flow-max, TR, and AP in patients with good Kelly-Scores were significantly higher than those in patients with fair Kelly-Scores (P < .05). (3) The Flow-max accurately reflected the TR, Kelly-Scores, and AP. Flow-max >45 mL per second, TR >70%, or AP >30 mm Hg was statistically regarded as a borderline level of fecal continence (P < .002). Conclusions: The Flow-max and FFP are considered to be useful parameters for postoperative patients with HD.
