Insights

Partial internal sphincter myomectomy in transanal pull-through surgery for Hirschsprung disease (HD) reduces complications. This technique improves outcomes without negatively impacting patient continence.

Area of Science:

  • Pediatric Surgery
  • Gastroenterology
  • Surgical Innovation

Background:

  • Hirschsprung disease (HD) is a congenital condition affecting the large intestine.
  • The transanal one-stage pull-through operation is a common surgical approach for HD.
  • Optimizing surgical techniques to minimize complications and preserve function is crucial.

Purpose of the Study:

  • To evaluate the efficacy of partial internal sphincter myomectomy during the transanal one-stage pull-through operation for HD.
  • To compare postoperative complications and continence outcomes between partial myomectomy and simple internal sphincter dissection.

Main Methods:

  • A prospective study included 153 pediatric patients with HD undergoing transanal one-stage pull-through.
  • Patients were divided into two groups: partial internal sphincter myomectomy (77 cases) and simple internal sphincter dissection (76 cases).
  • Postoperative complications and continence (Kelly score) were assessed and compared between groups.

Main Results:

  • The partial myomectomy group showed significantly lower rates of rectal muscularis infection, enterocolitis, anastomosis stenosis, and abdominal distension.
  • Antibiotic administration duration was shorter in the partial myomectomy group.
  • There was no statistically significant difference in postoperative continence between the two groups.

Conclusions:

  • Partial internal sphincter myomectomy is a safe and effective adjunct to the transanal one-stage pull-through operation for Hirschsprung disease.
  • This technique significantly reduces the incidence of key postoperative complications.
  • The procedure does not compromise, and may even help preserve, long-term bowel function and continence.
