title: Laparoscopy-assisted surgery for male imperforate anus with rectourethral fistula.
abstract: Laparoscopically assisted anorectal pull-through (LAARP), first described by Georgeson, is now considered to be the radical surgical treatment of choice for rectourethral fistula (RUF) in boys with high/intermediate-type imperforate anus. Accurate positioning of the pull-through canal, with pelvic floor muscles surrounding it symmetrically, is well recognized as the most important prognostic factor irrespective of the procedure performed. Surgical intervention should be LAARP with intraoperative measurement of the RUF, with follow-up focused on bowel habit. Complications such as diverticulum formation, have been reported with increasing frequency after LAARP and are most likely related to incomplete excision of the RUF, especially in bulbar cases. Thus, complete excision, while technically challenging, is crucial. Based on the results of a multicenter study comparing LAARP with other surgery, the most reliable investigation for detecting the presence of a diverticulum is MRI. At Juntendo University Hospital in Tokyo, Japan, blunt dissection with mosquito forceps to identify the potential pull-through canal, measuring the length of the RUF directly, and closer placement of trocars (in bulbar fistula cases) are homegrown refinements that we feel improve outcome and we present a review of our approach to the surgical management of ARM.
