FIELD: medicine.
SUBSTANCE: invention relates to medicine and namely to oncology and oncoradiology. A metal conductor is directed through the tumor stenosis along the true lumen of the choledochus. Material is collected for histological examination from different places of tumors of the pancreatic head and the distal section of the choledochus. At the same time, percutaneous puncture external-internal drainage of the bile ducts and endoscopic papillosphincterotomy of the large duodenal papilla are performed.
EFFECT: method makes it possible to limit oneself to anesthesia, to reduce the X-ray load on the patient and medical personnel, to reduce the likelihood of postoperative complications, and to reduce the period of inpatient treatment of the patient.
