The single stage transanal pull-through (SSPT) for Hirschsprung’s disease is becoming the most popular procedure. This single center study compared the result of single stage operation with two-stage operation for Hirschsprung’s disease in neonates.
Methods
We retrospectively reviewed medical records of all patients who were diagnosed as Hirschsprung’s disease and underwent SSPT or two-stage operation operation in Asan Medical Center between January 2003 and July 2014.
Results
There were 17 SSPT and 28 two-stage operation. The mean age of SSPT group was 14.2±7.1 days, and the mean age of two-stage operation group was 15.4±8.6 days for stomy formation, and 188.6±36.3 days for Duhamel operation. The operation time of SSPT was shorter than Duhamel operation (145.0±37.0 minutes vs. 193.0±36.0 minutes, p<0.001). The mean follow-up period of SSPT and two-stage operation was 35.5±34.9 months (range, 2-132 months) and 56.6±35.5 months (range, 1-121 months), respectively. Defecation problem rate such as fecal soiling or fecal impaction showed no significant difference between the two groups (p=0.719). Two SSPT patients required botulinum toxin injection due to rectal stenosis. Three patients of SSPT group underwent re-do endorectal pull-through due to remnant aganglionic or hypoganglionic bowel.
Conclusion
The SSPT showed shorter hospital days. However, few patients experienced rectal stenosis, but were manageable with botulinum toxin injection. The SSPT requires experienced-pathologist, as well as surgeon, because intra-operation pathology reading is critical for appropriate SSPT. SSPT is a feasible and reasonable option to treat Hirschsprung’s disease.
