Classification Of Ptc Needle By Percutaneous Hepatic Puncture Cholangiography

Percutaneous hepatic puncture catheter drainage (PTCD), after the treatment of PTC in patients with severe obstructive jaundice, can not only prevent the risk of peritonitis caused by PTC leakage, but also temporarily relieve the obstructive gangrenous disease, improve liver function, and prepare for the preoperative operation. In addition, patients with cholangitis can be treated to boils by rinsing through a drainage catheter and administering antibiotics.

Endoscopic retrograde cholangopancreatography (ERCP) : Fiberduodenoscope is used to intubate the papilla into the bile duct or pancreatic duct for direct retrograde angiography, which can understand the conditions of the duodenal papilla, clearly display the biliary and pancreatic duct system, and identify the location and lesion scope of internal and external hepatic bile duct obstruction. But it can cause complications such as acute pancreatitis and cholangitis. The nipple and Oddi sphincter have been incised by duodenoscope or intubated into the bile duct for stone extraction and drainage.
