摘要
Purpose: The objective of this study is to evaluate the anorectal function fr om the viewpoint of fecoflowmetry in postoperative patients with Hirschsprung’ s disease (HD). Methods: This study evaluated 23 long- term follow- up patient s 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. Aft er discussing the maximum defecation flow (Flow- max), fecoflow pattern (FFP), tolerance rate (TR), anal canal pressure (AP), and Kelly’s clinical scores (Ke lly- Scores), the significant parameters were i dentified to elucidate the anorectal activity. Results: (1) A close relations hip was observed between the FFP and Kelly- Scores (P = .0027). (2) Flow- max, TR, and AP in patients with good Kelly- Scores were signifi- cantly higher th an those in patients with fair Kelly- Scores (P < .05). (3) The Flow- max accu rately reflected the TR, Kelly- Scores, and AP. Flow- max > 45 mL per second, TR >70% , or AP > 30 mmHg was statistically regarded as a borderline level of f ecal continence (P < .002). Conclusions: The Flow- max and FFP are considered t o be useful parameters for postoperative patients with HD.
