Re-operations for Hirschsprung's disease: long-term complications

Area of Science:

• Pediatric Surgery
• Gastroenterology
• Genetics

Background:

• Hirschsprung's disease (HD) can necessitate reoperation when initial surgery fails, leading to persistent symptoms like inflammation and obstruction.
• Limited data exists on the long-term outcomes for patients undergoing repeat surgeries for complicated HD.
• Understanding outcomes of reoperations is crucial for improving management strategies in challenging HD cases.

Purpose of the Study:

• To evaluate the long-term clinical outcomes of patients with complicated Hirschsprung's disease requiring reoperation.
• To identify indications for reoperation and associated postoperative complications.
• To assess the effectiveness of repeat surgical interventions in improving symptoms and quality of life.

Main Methods:

• A retrospective follow-up of 8 patients with complicated HD requiring reoperation between 2004 and 2006.
• Recorded data included prior procedures, histology, reoperation indications, and postoperative follow-up.
• Long-term outcomes assessed included stool patterns, nutrition, and micturition.

Main Results:

• Follow-up ranged from 3.0 to 5.5 years (mean 4.4 years).
• Indications for reoperation included blind rectal pouch, persistent aganglionosis, and stenosis.
• Complete stool continence achieved in 4 patients; partial incontinence or soiling persisted in 3.
• Postoperative complications occurred in 4 patients, including ulceration and impaired colonic transit.
• Micturition was normal in 7 patients; one with trisomy 21 had partial continence.

Conclusions:

• Repeat surgical intervention improved symptoms in all patients, though resolution was delayed.
• Partial stool incontinence or soiling persisted in 3 patients.
• Many complications leading to reoperation, particularly residual aganglionosis, are preventable with meticulous primary surgery.
