Abstract
A clamp for esophageal end-to-end anastomosis has been designed and tested experimentally in 33 piglets. Eighteen anastomoses involved the entire esophageal wall, and 15 the mucosal layer alone. The results were evaluated on the basis of clinical, cineradiographic, gross and microscopic examinations. The width of the anastomoses was assessed under standardized conditions.The experience gained from the present series indicates that the sutureless technique provides a fairly tight seal for the prevention of leak. Irrespective of the type of clamp anastomosis, healing invariably occurred with anastomotic stricture.The onset of the stricturing process was early and rapidly progressive.Cineradiographic studies provided conclusive evidence of stricture and demonstrated concurrent motility disturbances in the distal esophagus.Inflation and radiography of the specimen under a standard degree of filling consistently showed reduction of lumen and elasticity at the anastomotic line.Histologic evidence demonstrated e...
