Minimally Invasive Neonatal Surgery: Hirschsprung Disease

Area of Science:

• Pediatric Surgery
• Colorectal Surgery
• Surgical Anatomy

Background:

• Hirschsprung disease is a congenital condition requiring surgical correction.
• Transanal pull-through (TAPT) is a primary surgical approach for Hirschsprung disease.
• Optimal surgical landmarks are critical for successful TAPT outcomes.

Purpose of the Study:

• To advocate for the use of the anorectal line (ARL) over the dentate line (DL) in TAPT procedures.
• To highlight the importance of preserving the anal transition zone during TAPT.
• To emphasize objective assessment of postoperative bowel function (POBF).

Main Methods:

• Laparoscopic-assisted transanal pull-through (TAPT) technique.
• Dissection initiated at the anorectal line (ARL) instead of the dentate line (DL).
• Focus on maintaining the integrity of the anal transition zone and posterior rectal cuff.

Main Results:

• The ARL provides a more objective landmark compared to the subjective DL.
• Using the ARL minimizes the risk of injury to sensory nerves crucial for defecation.
• Preservation of the anal transition zone and posterior rectal cuff is vital for normal bowel function.

Conclusions:

• Laparoscopic-assisted TAPT using the ARL is recommended for optimal POBF in Hirschsprung disease.
• The ARL is a superior landmark for TAPT dissection, safeguarding delicate innervation.
• Objective POBF assessment is crucial for long-term patient management and complication detection.
