ObjectiveTo assess the effectiveness and prognosis of different radical surgery for Hirschsprung disease (HD).MethodsThe bowel function of HD patients undergoing the anus modified Soave operation (84 cases,modified Soave group),modified Swenson operation (60 cases,modified Swenson group),modified Duhamel operation (76 cases,modified Duhamel group) was followed up by 3,6 months and 2 years after surgery.Long-term bowel function,clinical type,removal length,anorectal manometry,barium enema were analyzed and compared among three groups.ResultsThe occurrence rates of bowel dysfunction 3,6 months and 2 years after surgery in modified Soave group[17.9％(15/84),7.1％(6/84),4.8％ (4/84)] were significantly lower than those in modified Swenson group[41.7％ (25/60),21.7％(13/60),18.3％(11/60) ] and modified Duhamel group [ 36.8％ (28/76),18.4％ (14/76),13.2％(10/76) ].There was significant difference between modified Soave group and modified Swenson group,modified Duhamel group(P＜ 0.05 ).There was no significant difference between modified Swenson group and modified Duhamel group (P ＞ 0.05).When the removal length ≤35 cm,the occurrence rate of bowel dysfunction after surgery in modified Soave group [ 18.7％ (14/75)] was lower than that in improved Swenson group [ 39.5％ ( 17/43 ) ] and modified Duhamel group [ 34.4％ (21/61 ) ].There was significant difference between modified Soave group and modified Swenson group,modified Duhamel group (P ＜ 0.05).There was no significant difference between modified Swenson group and modified Duhamel group (P ＞ 0.05).When the removal length ＞ 35 cm,there was no significant difference in the occurrence rate of bowel dysfunction after surgery among three groups (P ＞ 0.05 ).The occurrence rates of bowel dysfunction in short-segment type and common type in modified Soave group was lower than those in modified Swenson group and modified Duhamel group.There was significant difference between modified Soave group and modified Swenson group,modified Duhamel group(P ＜ 0.05).There was no significant difference between modified Swenson group and modified Duhamel group (P＞ 0.05).The anorectal angle 2 years after surgery in modified Soave group [(93.67 ± 10.50)° ] was less than that in modified Swenson group [(110.20 ± 11.88)° ] and modified Duhamel group [(106.33 ± 12.21)° ].There was significant difference (P ＜0.05).ConclusionThe complication and trauma are significantly lower in the anus modified Soave operation than the modified Swenson operation and modified Duhamel operation,but the choice of surgery should be strictly controlled according to the anal HD treatment indications.
