Extensive intestinal aganglionosis.

Area of Science:

• Pediatric Surgery
• Gastroenterology
• Medical Genetics

Background:

• Hirschsprung's disease (HSCR) is a congenital disorder characterized by the absence of ganglion cells in the distal bowel.
• Extensive aganglionosis, including forms near the ligament of Treitz and total intestinal aganglionosis, represents rare and severe variants of HSCR.
• These extensive forms present significant challenges in maintaining nutrition, fluid, and electrolyte balance in affected infants.

Purpose of the Study:

• To report on four cases of extensive intestinal aganglionosis, including one case of total intestinal aganglionosis with gastric involvement.
• To highlight the clinical challenges and management difficulties associated with these rare HSCR variants.
• To underscore the limitations of current surgical interventions for extensive aganglionosis.

Main Methods:

• Case series reporting on four patients diagnosed with extensive or total intestinal aganglionosis.
• Review of clinical presentation, nutritional management, and surgical considerations.
• Discussion of the Ziegler myectomy-myotomy technique and its applicability.

Main Results:

• Four cases of extensive intestinal aganglionosis were identified, with one patient exhibiting total intestinal aganglionosis extending to the stomach.
• Patients faced severe difficulties in nutritional support and fluid/electrolyte management.
• The Ziegler myectomy-myotomy technique, while promising, has not yet been established as an effective treatment for these rare, extensive forms.

Conclusions:

• Extensive and total intestinal aganglionosis are rare but severe forms of Hirschsprung's disease with significant management challenges.
• There is a pressing need for the development and validation of effective surgical strategies for these conditions.
• Further research is warranted to improve outcomes for patients with extensive aganglionosis.
