METHOD FOR TAKING MAJOR DUODENAL PAPILLA MUCOSA BIOPSY SAMPLE WHEN PERFORMING DUODENOSCOPIC EXAMINATION Russian patent published in 2004 - IPC

FIELD: medicine.

SUBSTANCE: method involves carrying out preparative medicamentous treatment with M-anticholinergic and sedative agents being parenterally administered. Individual topographic and anatomic disposition is checked and common hepatic and main pancreatic duct condition is estimated in advance. Major duodenal papilla tissue sample is taken using biopsy forceps having branches opening at right angle on one side in the following manner. Open forceps branch retaining its initial straight position is introduced into major duodenal papilla orifice or into the common hepatic duct orifice in the cases of common hepatic duct and main pancreatic duct having separate flow-in condition. The open branch is set by rotating the forceps into the position allowing major duodenal papilla tissue capture from a position maximum far away from main pancreatic duct orifice. Visual estimation of major duodenal papilla structure is completed with cannulation in particular cases when necessary, instrumental palpation of major duodenal papilla orifice with soft Teflon catheter, X-ray-contrasting and/or endoscopic ultrasonic examination of outlet duct parts. Nitroglycerin is administered in sublingual mode and H-2 blocker and/or baralgin solution are parenterally administered in particular cases to patients immediately after taking major duodenal papilla tissue sample and finishing duodenoscopic examination. Taking meals is permitted not earlier as 6 h later after the procedure. Quamatel is applied as H-2 blocker.

EFFECT: reduced risk of traumatic complications; maximum information containing in diagnostic purpose materials.
