Small bowel biopsy by coaxial catheter. A simple, rapid technique.

A new small intestinal biopsy technique was developed and evaluated: it involves the rapid replacement of a simple duodenal tube using a controllable spring guide and fluoroscopy. A suction biopsy catheter was then passed coaxially through the tube as often as needed for sampling, after which other diagnostic studies were done with the same intubation. In clinical trials totaling 31 biopsies in 15 adult patients, the method proved safe and effective. Currently, the time required to intubate the ligament of Treitz and obtain two biopsies is usually less than 15 minutes.

Reflux cholangiography in sphincteroplasty or enterobiliary anastomosis.

Reflux cholangiography is an extension of hypotonic duodenography. In patients with abnormal enterobiliary communications, it is a rapid, effective method for demonstrating not only biliary and occasionally pancreatic ducts, but also fistulas, the duodenum, and the papilla of Vater. It is especially useful for preoperative evaluation of strictures for it enhances both the value and success of endoscopic cholangiopancreatography.

Transjugular approach to the liver, biliary system, and portal circulation.

More than 5 years of clinical and animal experience with the use of a transjugular approach to the liver, biliary system, and portal circulation is reviewed. It has been of clinical value in connection with hepatic manometry and venography, liver biopsy, and cholangiography. Satisfactory hepatic manometry and venography were achieved by the transjugular approach in all 47 cases where attempted; diagnostic liver specimens were obtained in 71 of 83 patients (86%); and cholangiography was successful in 48 of 52 patients with enlarged intrahepatic ducts (92%). No complications occurred with these studies. In animals, transjugular catheterization was used as a means for portal, mesenteric, and pancreatic venography. These procedures are ready for diagnostic clinical use. Therapeutic techniques explored in animals include intravascular tamponade of gastric coronary vein and the nonsurgical creation of intrahepatic portacaval shunts, both of promise in the future management of massive gastrointestinal bleeding from varices.
