Abstract
Twelve cases receiving endoscopic sphincterotomy (EST) were examined, including 11 cases of common bile duct stones (CBDS), 1 case of obstructive jaundice due to extrinstic compression of the common bile duct (CBD) which was secondary to distant metastasis of spindle cell tumor. Eight cases of CBDS were successfully removed, with 1 failed cannulation, 1 failed extraction of CBDS, and in] case, the procedure had to be terminated because of bleeding. EST for extrinsic CBD compression was performed successfully for double endoscopic nasobiliary drainage (ENBD). Complications included] pancreatitis, which was eliminated by conservative treatment, and 1 bleeding which had to be operated on. Alternately using an ENBD catheter and a needle knife sphincterotome (NKS) can help to relieve the preexisting cholangitis and facilitate the following sphincterotomy in some difficult cases.
