Abstract

Background

ERCP may be unsuccessful because of the presence of a complex peripapillary diverticulum, prior surgery, obstructing tumor, papillary stenosis, or impacted stones. Percutaneous transhepatic cholangiography is a classic technique for accessing the bile duct and remains the primary alternative when biliary ERCP is unsuccessful. With the evolution of interventional EUS, additional options are available for management of biliary obstruction.

Methods

EUS cholangiography was performed, after which the puncture was enlarged to form an enterocholedochal fistula that was used for interventions that resulted in biliary decompression in 5 patients with obstructive jaundice.

Observations

Cholangiography was readily performed in all 5 patients. In one patient, a guidewire could not be manipulated across the papilla via the enterocholedochal fistula, necessitating percutaneous intervention. Biliary decompression was achieved in the other 4 patients, in the last two, as a single procedure.

Conclusions

Interventional EUS cholangiography is a new technique that allows drainage of a dilated biliary system when the bile duct is inaccessible by conventional ERCP.

Patients and methods

Five consecutive patients with obstructive jaundice in whom conventional ERCP was unsuccessful underwent interventional EUS-guided cholangiography (IEUC) with the intent of ductal decompression (Table 1). Our institutional review board waived formal review and approval of the procedures because they were considered extensions of existing procedures.

A standard echoendoscope (GF-UCT140; Olympus America Corp., Melville, N.Y.) was used for all interventions. The extrahepatic bile duct was measured

Observations

All patients were hospitalized for observation after IEUC; jaundice resolved in all cases (Table 2). Patient 3 developed ascites and fever, and paracentesis revealed serosanguinous bile-stained fluid. A percutaneous 7F pigtail catheter was placed in the pelvic fluid collection under US guidance. ERCP was repeated, and injection of contrast through the gastrocholedochal stent did not demonstrate a leak. The peritonitis resolved within 3 weeks, and the percutaneous catheter was removed. There was

Discussion

EUS has impacted interventional endoscopy in many ways. With this modality, detailed imaging can be obtained because of the close proximity of the high-frequency transducer to the region of interest.14 The ability to place a needle in the EUS field has increased diagnostic and therapeutic capability, including FNA,12., 13. celiac plexus neurolysis,7., 15. drainage of cystic lesions,11., 16. and pancreaticogastrostomy.17 The distal biliary and pancreatic ducts are readily identified when an

    Furthermore, biliary rendez-vous technique with EUS completed the therapeutic arsenal of EUS-BA. A puncture of the bile duct is performed allowing insertion of a guidewire facilitating conventionnel ERCP access through the papilla [39]. A recently published meta-analysis reported technical success rate for EUS-HGS and EUS-CDS of 93.7% and 94.1% respectively [40].

    It may be appropriately used after failed ERCP attributable to periampullary diverticula, tortuous bile ducts, impacted stones, or malignancy with bile-duct infiltration. Transpapillary drainage via EUS-BD can be attempted using classic rendezvous, parallel rendezvous,9 or standard cannulation, without rendezvous, after cholangiography by contrast injection through an EUS needle.10,11 In this procedure, under EUS and Doppler guidance a needle is inserted into either the left hepatic or common bile duct.
