Second time lucky-Managing metastatic peri-ampullary tumor with cholangitis


This 65 year old lady had been admitted with obstructive jaundice and cholangitis secondary to a metastatic peri-ampullary tumor. We encountered a swollen ampulla on duodenal intubation (A). Cannulation and contrast injection outlined a significantly dilated pancreatic duct (B: Black arrows) and what appeared to be the accessory duct (B: White arrow). We did a pancreatic papillotomy (C: White arrow). Further attempts here were unsuccessful and slight scope with-drawl showed an opening at the upper surface of the ampulla seen in image A (D: Black arrow), which was cannulated (E: Black arrow). This was the proper route as evidenced by wire cannulation (F: Black arrows). Contrast injection in this area outlined a dilated proximal bile duct and intrahepatic channels (G: White arrows) with no distal or mid duct delineation. A 10 mm diameter and 8 cm long partially uncovered metallic stent was prepped (I. We used a Micro-Tech stent. These come with an internal stiffening wire with a ring for removal prior to insertion: Red arrow). The stent assembly was placed across the strictured segment unto the dilated duct (J: Black arrows). The stent was then deployed (K1: The stent being deployed. Red arrow marks the gold reference mark which is kept visible just at the edge of field of view. K2: The deployed stent. A gush of contrast and white pus was seen. L1 & L2: White arrows show the fully deployed stent with black arrows indicating the proximal and distal radiographic markers).

This 60 year old gentleman had earlier undergone ERCP and stenting for an anastomotic biliary leakage a few months earlier http://ercp365.bl...
