Procedure: ERCP
with sphincterotomy and removal of common duct stone
Indications for Procedure:
The patient is a 62-year-old woman with documented
obstructing common duct stone. She is status post
T-tube insertion for creation of a biliary drainage
tract. She now presents for sphincterotomy and stone
removal.
Description of Procedure:
The patient was brought to the endoscopy suite and
sedated with IV Versed and Fentanyl. After the pharynx
was anesthetized with Xylocaine spray, a guidewire
and snare were advanced through the external biliary
drain site into the duodenum.
Next the side-viewing
duodenoscope was inserted per os and advanced into
the esophagus, stomach, and duodenum. Esophageal,
gastric, and duodenal mucosa were all noted to be
unremarkable. The scope was positioned in place and
a guidewire was grasped by the external snare and
pulled up into the bile duct and out through the skin.
The sphincterotome was
then advanced over the guidewire up into the bile
duct and positioned across the papilla of Vater. The
papilla was noted to be lying in the base of a large
duodenal diverticulum. The sphincterotomy was then
performed to a total of 1.0 cm. There was a moderate
amount of bleeding that resolved spontaneously. Estimated
blood loss was less than 25 cc. Next a 1.1 mm. balloon
was advanced over a guidewire up into the bile duct
and pulled out clearing the duct of all gravel and
small stone material.
Before concluding the
procedure, a follow-up cholangiogram was performed
and revealed no further evidence of stones within
the duct. There was free flow of contrast out to the
T-tube site, revealing a well-established drainage
tract. A mild stricture of the right hepatic duct
was observed, but no residual stones were seen. During
the procedure the pancreatic duct was also visualized
and appeared to be patent and of normal caliber. It
is anticipated that excellent drainage has been established.
The procedure was thus terminated and all instruments
were withdrawn. The patient tolerated the procedure
well. She will be discharged after recovery from sedation.
