title: Retroperitoneal duodenal perforation during endoscopic sphincterotomy: sonographic findings.
abstract: We present the sonographic findings in 5 cases of retroperitoneal duodenal perforation during endoscopic sphincterotomy. In each case, sonography showed hyperechoic areas associated with shadowing and ring-down artifacts between the liver and the right kidney correlating with the retroperitoneal air seen on plain x-ray films. This brightly echogenic area with shadowing surrounded and obscured the kidney. In 4 patients, resolution was documented on follow-up sonographic examinations in agreement with other radiologic findings; the other patient died.
