OBJECTIVE

To improve the outcomes after orthotopic liver transplantation (OLT) followed by early biliary complications via endoscopic bilioduodenal stenting.

MATERIAL AND METHODS

The study enrolled 41 patients with early biliary complications within 90 days after OLT. All patients underwent endoscopic treatment between 2001 and 2021. There were 34 (82.9%) men and 7 (17.1%) women aged 48.5±12.5 years. Strictures and failure of biliary anastomosis occurred in 33 (80.5%) and 8 (19.5%) patients, respectively.

RESULTS

After endoscopic treatment, serum bilirubin normalized in 3.3±0.86 days in patients with strictures (23.7 (16.4; 34.5) mmol/l, p<0.001). Diameter of lobar ducts as a criterion of biliary hypertension was normalized after 4 (2.5; 5.5) days (p<0.001). Bile leakage after stenting with a covered self-expanding stent regressed in all 7 patients after 3 (2; 5) days. In 1 patient, bile output through the drainage stopped in 8 days after bilioduodenal stenting with a plastic stent.

CONCLUSION

Endoscopic bilioduodenal stenting is always effective and minimally invasive treatment after liver transplantation followed by early biliary complications (failure or stricture of anastomosis). This approach minimizes postoperative complications (9.8%) that do not require surgical intervention (Clavien-Dindo grade I).
