Meta analysis of incidence of postoperative complications for the modified posterior sagittal anorectoplasty treatment of intermediate or high anorectal malformations / 中华胃肠外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the incidence of postoperative complications of children with intermediate or high anorectal malformations treated by one-stage modified posterior sagittal anorectoplasty(PSARP) by meta-analysis.</p><p><b>METHODS</b>Cases with intermediate or high anorectal malformations treated by one-stage modified PSARP nearly a decade at home and abroad were collected by searching in Wanfang Data, CNKI, and PubMed database, then all the papers that recorded the number of cases of postoperative complications were screened out according to inclusion and exclusion criteria. Meta package in RevMan 3.2.5 software was used to perform the meta analysis for rate, and logit conversion method was applied to calculate the merger of the rates. Firstly, heterogeneity inspection was carried out. If the result was P>0.05, it was the homogeneity between the instructions included in the literatures, the fixed effect model was chosen. If the results was P<0.05, the random effect model was chosen. Then rank correlation test was used to estimate the number of research to evaluate publication bias. If P was 0.05 or less, the difference was statistically significant.</p><p><b>RESULTS</b>Thirteen related articles were selected and added up to 566 cases with intermediate or high anorectal malformations treated by one-stage modified PSARP. The merged rate of the complications was 28%(95%CI 19% to 40%). The three highest rate of complications were 8%(95%CI4% ~ 14%) of corrupt dung, 7%(95%CI5% ~11%)of fecal incontinence and 5%(95%CI3% ~ 10%) of rectal mucosa prolapse.</p><p><b>CONCLUSION</b>The most common postoperative complications of children with intermediate or high anorectal malformations treated by one-stage modified PSARP are rectal corrupt dung and fecal incontinence.</p>
