Jejunal interposition hepaticoduodenostomy for bile duct dilatation may cause bile reflux gastritis, leading to abdominal pain. Roux-en-Y hepaticojejunostomy is a safer alternative for biliary reconstruction.

Area of Science:

Gastroenterology
Surgical Innovation
Pediatric Surgery

Background:

Congenital dilatation of the bile duct (choledochal cyst) necessitates surgical intervention.
Biliary reconstruction is crucial after excision of the dilated bile duct to ensure proper bile flow.
Roux-en-Y hepaticojejunostomy and jejunal interposition hepaticoduodenostomy are common reconstruction methods.

Purpose of the Study:

To compare the early and late complication rates of Roux-en-Y hepaticojejunostomy versus jejunal interposition hepaticoduodenostomy.
To investigate the incidence of bile reflux and associated gastritis after these procedures.

Main Methods:

Retrospective comparison of patients undergoing two different biliary reconstruction techniques.
Assessment of early and late complications, including abdominal pain.

Utilized 99mTc-pyridoxyl methyl tryptophan scintigraphy and gastroscopy to evaluate bile reflux and gastritis.

Main Results:

No significant difference in overall early or late complications between the two groups.
Recurrent abdominal pain was exclusively observed in the jejunal interposition hepaticoduodenostomy group.
High incidence of bile reflux and associated chronic gastritis detected in patients who underwent jejunal interposition hepaticoduodenostomy.

Conclusions:

Jejunal interposition hepaticoduodenostomy may lead to bile reflux gastritis, a complication not observed with Roux-en-Y hepaticojejunostomy.
This study is the first to report bile reflux gastritis following jejunal interposition hepaticoduodenostomy.
Further research is needed to elucidate the mechanisms and long-term implications of bile reflux gastritis in this context.
