Objective: To explore the and radical postoperative anorectal pressure change and bowel function by anal Modified Soave I period megacolon. Methods: January 2007 - January our hospital diagnosis clearly and surgical treatment of 51 cases of Hirschsprung follow-up of 49 cases, including anal Modified Soave I period radical megacolon 34 cases, the ordinary 27 cases, short segments in 6 cases, the long segment type 1 cases, surgery age from 1 month to 6 years in April, an average of 1.5 years; treatment of abdominal perineal Soave operation megacolon 15 cases, of which the ordinary nine cases, five cases of long segment type, full the colonic Hirschsprung cases, age at surgery was 3 years old -10 years old in May, an average of 4.9 years; and select the 20 cases of children the undergraduate hospitalized gastrointestinal diseases defecation normal control group. Anorectal manometry were performed in all cases followed up, asking the daily number of bowel movements, stool, with or without constipation, incontinence and fecal pollution affecting the daily group life, whether to use laxatives, whether on postoperative June December anal function compare two groups anorectal pressure changes as well as the impact on bowel function. RESULTS: The anal Modified Soave I period megacolon radical 34 cases June after anal function evaluation: excellent in 20 cases, good in 11 cases, the poor two cases, poor in 1 case, good rate of 91.17%, abdominal perineal Soave I period 15 cases of megacolon radical mastectomy, excellent in 7 cases, good in 3 cases, the poor three cases, poor in 2 cases, excellent rate of 66.67%, and two sets of excellent cases comparing P gt; 0.05; December after two sets of anal function evaluation anus improvement group, were excellent in 28 cases, good in 5 cases, poor one cases, excellent rate of 97.06%, three cases of abdominal perineal group, excellent in 8 cases, good in 3 cases, poor, poor in 1 case, good rate of 73.33% the two groups, P lt; 0.05; anal Modified Soave I period megacolon radical postoperative rectal resting pressure, anal resting pressure, significantly reduce and shorten the length of the high-pressure zone in the anal canal compared with preoperative P lt; 0.05; anal Modified Soave I period megacolon after radical occur in children with fecal pollution anal resting pressure was significantly lower than the control group, P lt; 0.05; 12 months after the anal improved postoperative fecal pollution in children with anal resting pressure with increasing tendency, including four cases of anal resting pressure close to normal, two cases of anorectal inhibitory reflex, anal function evaluation was excellent; improved postoperative anorectal inhibitory reflex recovery was significantly higher than that of an abdominal perineal surgery through the anus, P lt ; 0.05; anal Modified Soave I period megacolon after radical cases of constipation, anal stenosis. Conclusion: anal Modified Soave I period megacolon after radical children may be better bowel function and postoperative anorectal pressure return to normal, and part of the anorectal inhibitory reflex has been restored.
