Balloon dilation of congenital perforated duodenal web in newborns: Evaluation of short and long-term results.

BACKGROUND

Incomplete congenital duodenal obstruction (ICDO) is caused by a congenitally perforated duodenal web (CPDW). Currently, only six cases of balloon dilatation of the PDW in newborns have been described.

AIM: To present our experience of balloon dilatation of a perforated duodenal membrane in newborns with ICDO.

METHODS

Five newborns who underwent balloon dilatation of the CPDW along a preinstalled guidewire between 2021 and 2023 were included. Nineteen newborns diagnosed with ICDO who underwent laparotomy were included in the control group.

RESULTS

In all cases, good anatomical and clinical results were obtained. In three cases, a follow-up study was conducted after 1 year. The average time to start enteral feeding per os was significantly earlier in the study group (4.4 d) than in the laparotomic group (21.2 days; P < 0.0001). The time spent by patients in the intensive care unit and hospital after balloon dilatation was also significantly shorter. We determined the selection criteria for possible and effective CPDW balloon dilatation in newborns as follows: (1) Presence of dynamic radiographic signs of the passage of a radiopaque substance beyond the zone of narrowing or radiographic signs of pneumatisation of the duodenum and small bowel distal to the web; (2) presence of endoscopic signs of CPDW; (3) successful cannulation with a guidewire performed parallel to the endoscope, with holes in the congenital duodenal web; and (4) successful positioning of the balloon performed along a freestanding guidewire on the web.

CONCLUSION

Strictly following selection criteria for newborns with ICDO caused by CPDW ensures that endoscopic balloon dilatation using a pre-installed guidewire is safe and effective and shows good 1-year follow-up results.
