Gallbladder ablation by means of injection of hot contrast medium was attempted in 13 dogs. Room temperature contrast medium was injected into the gallbladders of two additional dogs (controls). After midline laparotomy was performed to expose the ga

Labile type-specific antigen of Moraxella catarrhalis

Autor: J W Vennes, S J Norkus

Publikováno v: Journal of Clinical Microbiology. 28:2815-2817

By using hot acid extract and double-diffusion studies, an antigen isolated from clinical strains of Moraxella catarrhalis, designated the C antigen, was studied. The antigen is labile, relatively trypsin insensitive, and either polysaccharide or gly

Cystic duct anatomy: an endoscopic perspective

Autor: M J, Shaw, P J, Dorsher, J A, Vennes

Publikováno v: The American journal of gastroenterology. 88(12)

Knowledge of the junction of the cystic and common hepatic duct is essential for endoscopic management of biliary tract disease. The cystic and common hepatic ducts were evaluated retrospectively in cholangiograms obtained for a variety of indication

Results of a multicenter trial using a mechanical lithotripter for the treatment of large bile duct stones

Autor: M J, Shaw, R D, Mackie, J P, Moore, P J, Dorsher, M L, Freeman, P B, Meier, T, Potter, S W, Hutton, J A, Vennes

Publikováno v: The American journal of gastroenterology. 88(5)

A prospective, uncontrolled trial of the use of a prototype mechanical lithotripter was performed in 116 patients at nine centers. Standard endoscopic approaches had failed to remove all stones, primarily because of large size (80% of patients). For

Publikováno v: Gastrointestinal endoscopy. 38(2)

Endoscopic monopolar and bipolar devices were compared during cutting and coagulation. It was observed on appropriate animal models that the initial resistance (impedance) values recorded correspond to the normal tissue impedance at the electrode. Th

In vivo evaluation of monopolar versus bipolar electrosurgical polypectomy snares

Autor: R D, Tucker, C E, Platz, C E, Sievert, J A, Vennes, S E, Silvis

Publikováno v: The American journal of gastroenterology. 85(10)

The energy required and tissue damage in bipolar and monopolar polypectomy snares were compared in a canine model. The bipolar snare required an average of 34 joules of energy, whereas the monopolar snare required 228 joules to cut the same diameter

A new mechanical lithotripter for the treatment of large common bile duct stones

Autor: M J, Shaw, P J, Dorsher, J A, Vennes

Publikováno v: The American journal of gastroenterology. 85(7)

A prospective uncontrolled multi-center trial of a prototype mechanical lithotripter was performed in 30 patients with common bile duct calculi. Standard endoscopic sphincterotomy had failed to remove all stones, primarily because of large size (26 p
