Endoscopic Decompression with a Transanal Drainage Tube for the Treatment of Hirschsprung's Disease in Newborns

To evaluate the effectiveness and safety of endoscopic decompression with a transanal drainage tube (ED-TDT) in the treatment of neonatal Hirschsprung's disease (HD). Six newborns (4 boys and 2 girls; age at operation 9-29 days, median 24 days) were admitted to our hospital due to the delayed passage of meconium after birth, abdominal distension, and vomiting. HD was diagnosed by the retrograde enema radiography. All patients underwent ED-TDT for decompression of the dilated colon. During the operation, an endoscope was inserted through the anus to the ascending colon or ileocecal region, which was then used to insert a guidewire to the ascending colon. The endoscope was then removed, and a colorectal drainage tube was introduced over the guidewire. This drainage was placed until a pull-through procedure was performed. The ED-TDT was successfully performed in all newborns. The intraoperative rectal biopsy confirmed the diagnosis of HD. The duration of the operation was 25-70 minutes (median 52.5 minutes). There were no perforations, bleeding, or other complications after surgery. After surgery, the abdominal distention was significantly relieved, and the babies could be fed with milk after 6 hours. These babies were discharged after 2-11 days (median 2.5 days) and underwent a pull-through procedure after 1-3 months (median 3 months). ED-TDT is a safe and effective treatment for neonatal HD before a pull-through procedure. It could be used as an alternative therapy to colostomy.
