[RENTGENOENDOSCOPIC INTERVENTIONS FOR BILIARY OBSTRUCTION OF NON-TUMOR GENESIS]

We analyzed the immediate and long-term results of endoscopic diagnostic and therapeutic interventions in patients on the non-tumor obstruction of the bile ducts. Application of the developed diagnostic algorithm using ultrasound, fistulocholangiography, computer and magnetic resonance imaging, endoscopic retrograde cholangiopancreatography, diagnostic endoscopic papillosphincterotomy, instrumental revision of bile ducts, transduodenal holedohoscopy provided sensitive diagnostic reasons of non-tumor biliary obstruction to (94.2 +/- 1.7)%. Optimization of treatment strategy developed with the introduction of the clinic endobiliary endoscopic intervention has achieved positive results in 83.7% of patients, reducing the morbidity of 1.7%, mortality--0.9%.
