Laparoscopically assisted anorectoplasty-Surgical procedures and outcomes: A literature review.

Anorectal malformation includes various types of anomalies. The goal of definitive surgery is achievement of fecal continence. Twenty years have passed since laparoscopically assisted anorectoplasty (LAARP) was reported by Georgeson. Since LAARP is gaining popularity, its long-term outcomes should be evaluated. Presently, there is no evidence regarding the optimal method of ligating and dividing the fistula correctly and creating the pull-through canal accurately. Rectal prolapse and remnant of the original fistula (ROOF) tend to develop more often in LAARP patients than in posterior sagittal anorectoplasty (PSARP) patients; however, robust evidence is not available. Prolapse may be prevented by suture fixation of the rectum to the presacral fascia; however, if prolapse occurs, the indication, timing, and the best method for surgical correction remain unclear. Most patients with ROOF are asymptomatic, and there is controversy regarding the indications for ROOF resection. This article aimed to detail the various modifications of the LAARP procedures reported previously and to describe the surgical outcomes, particularly focusing on rectal prolapse, ROOF, and fecal continence, by reviewing the literature. Functional outcomes after LAARP were almost similar to those noted after PSARP, and we have demonstrated that LAARP is not inferior to PSARP with respect to fecal continence. Although there is controversy regarding the application of LAARP for recto-bulbar cases, we believe that LAARP is still evolving, and we can achieve better outcomes by improving the procedure.
