Summary of ERCP Findings (N = 12).

Authors (reference)	Number	ERCP findings and interventions
Roth et al.4	2	Extraction of stones and sludge.
Rojas et al.11	1	Negative for Choledocholithiasis.
Durazo et al.9	1	A small pigment stone retrieved Diffuse intrahepatic biliary strictures or cholangiopathy
Faraqui et al.13	4	Case 1: 1 Plastic CBD stent placed, Multiple biliary strictures were noted in the intrahepatic ducts, Stones removal, repeat ERCP in 1 month with removal of the stent. Case 2: 2 ERCPs done, stone removal, CBD stent placement and removal, and balloon dilation of strictures in the right and left hepatic ducts without improvement. Case 3: dilation of left main hepatic duct and placement of a plastic stent. Case 4: ERCP done after a bile leak after a laparoscopic cholecystectomy. Other eight patients did not undergo ERCP due to predominance of diffuse intrahepatic biliary tract abnormalities did not seem likely to be conductive to endoscopic intervention
Lee et al.14	1	Irregular intrahepatic radicals consistent with cholangiopathy. Loose stone material was removed from the CBD Biliary stent placed in bile duct Repeat ERCP on day 150 showed ductopenia and subtle ductal beading consistent with secondary sclerosing cholangitis
Tafreshi et al.15	1	Tortuous and attenuated intrahepatic bile ducts with normal caliber extrahepatic ducts
Linnewever et al.12	2	Inflammation, stricture formation and rarefication of the peripheral bile duct system consistent with SSC Choledocholithiasis Repeat ERCP three times with ductal dilation and stent implantation

ERCP, endoscopic retrograde cholangiography.
