Abstract

Laser welding of biliary tissues would be a valuable technique in conventional and endoscopic surgery. Laser welding would allow the avoidance of potentially lithogenic suture material as a sequela to biliary tract surgery. Laser welding would be compatable from the surgical technical standpoint with fiberoptic endoscopic intrumentation. The 2.15 micron thulium-holmium-chromium laser offers tissue penetration on the order of a few hundred microns. We have hypothesized that this laser might be well suited to performing biliary tissue welding. We evaluated this laser in vitro using canine gallbladder tissue and we were able to achieve histologically satisfactory tissue fusion and immediate bursting strengths above physiologically encountered biliary pressures.
