Midterm postoperative clinicoradiologic analysis of surgery for high/intermediate-type imperforate anus: prospective comparative study between laparoscopy-assisted and posterior sagittal anorectoplasty

Comparison of clinical outcomes and anorectal manometry in patients with congenital anorectal malformations treated with posterior sagittal anorectoplasty and laparoscopically assisted anorectal pull through

“…More than 80% of the patients received a good or fair ranking, which correlates with related retrospective followup studies [6]. These are different results from the prospective study by Ichijo et al [9]. The difference may be caused by the age at the time of procedure and evaluation, as well as the clinical scoring system.…”

“…As we know, a prospective study has several advantages: more equilibrated randomized grouping, less confounding bias, and better comparability. A midterm prospective study was done by Ichijo et al [9] recently; it demonstrated that the LAARP had better postoperative clinical outcomes than PSARP for the treatment of high ARM, whereas patients had similar muscle mass size by radiologic analysis and similar white blood cell count that reflected surgical stress. However, in his work, the age at anorectoplasty was far older (8-9 months) than that in our study, and manometric methods were not used.…”

Laparoscopic-assisted anorectal pull-through for anorectal malformations: a systematic review and the need for standardization of outcome reporting

“…Analysis of study designs revealed 2 prospective studies (11.7%) [2,3], 4 comparative studies (23.5%) [2,[4][5][6], and no randomized studies.…”

Neuronal immaturity in normoganglionic colon from cases of Hirschsprung disease, anorectal malformation, and idiopathic constipation

“…Recently, we evaluated fecal continence after PT surgery in AM and demonstrated that continence evaluation questionnaire scores after Georgeson's laparoscopy-assisted anorectoplasty only improved 3 to 4 years after surgery [14]. Because the mean age at surgery was 9.6 months in that study, improvement in fecal continence was seen at approximately 4 to 5 years old.…”
