Is conventional sphincterotomy possible in patients with common bile duct stones impacted at the ampulla of Vater?
Artigo em Inglês | IMSEAR | ID: sea-124456
ABSTRACT

BACKGROUND:

Needle knife precut papillotomy has been used to gain access or remove impacted common bile duct stones at the ampulla of Vater. However, precut papillotomy is a risky procedure with high complication rates and is presumably best dealt with by the expert. We attempted to find out the feasibility of performing conventional endoscopic sphincterotomy in patients with impacted stones at the ampulla.

METHODS:

All patients undergoing endoscopic retrograde cholangiopancreatography for stones impacted at the ampulla between the years 2000 and 2005 were enrolled in the study. All attempts were made to achieve biliary cannulation through the conventional route including use of the long route or guidewire to cannulate the papilla. Needle knife papillotomy was resorted to only if attempts to cannulate the papilla through the conventional route failed. The success and complications of the procedures were recorded.

RESULTS:

Thirty-two patients were enrolled. The impacted bile duct stone could be removed in all the patients. Conventional endoscopic retrograde cholangiopancreatography and endoscopic sphincterotomy were performed in 23 patients with impacted stones. The long route had to be employed in seven patients while guidewire cannulation of the papilla was needed in four patients. Needle knife papillotomy was needed in only nine patients. None of the patients in whom the conventional route was employed developed complications, whereas bleed requiring endoscopic management was observed in three (33%) of the nine patients in whom needle knife papillotomy was performed.

CONCLUSIONS:

Endoscopic retrograde cholangiopancreatography and endoscopic sphincterotomy can be performed by the conventional route in the majority of patients with impacted stones at the ampulla. This approach appears to be safer than needle knife papillotomy. However, needle knife papillotomy may be required in patients in whom biliary access cannot be gained through the conventional approach.
