Laparoscopically assisted anorectal pull-through for high imperforate anus in infants: intermediate results

Area of Science:

• Pediatric Surgery
• Colorectal Surgery
• Minimally Invasive Surgery

Background:

• Congenital high imperforate anus presents significant surgical challenges.
• Evaluating novel surgical techniques is crucial for improving patient outcomes.
• Laparoscopically assisted anorectal pull-through (LAARP) is a less invasive approach.

Purpose of the Study:

• To assess the clinical outcomes and postoperative anal function in infants with high imperforate anus treated with LAARP.
• To compare LAARP with the established posterior sagittal anorectoplasty (PSARP) technique.

Main Methods:

• Retrospective comparison of 33 infants undergoing LAARP with 28 infants treated with PSARP.
• Evaluation of anorectal function using Kelly score, manometry, and MRI.
• Data collected between January 2004 and July 2007, with functional assessments between 3.1 and 4.4 years of age.

Main Results:

• LAARP resulted in a significantly shorter hospital stay compared to PSARP (P < .01).
• LAARP demonstrated improved manometric parameters, including higher resting anal canal pressure and larger vector volume (P < .05).
• While MRI showed lower rectal malposition rates with LAARP, this was not statistically significant; Kelly scores were comparable.

Conclusions:

• LAARP is a viable surgical option for high imperforate anus, achieving satisfactory fecal continence.
• LAARP offers advantages over PSARP, including reduced hospital stay and potentially better rectal alignment.
• Long-term follow-up is essential to fully elucidate the comparative benefits of LAARP versus PSARP.
