Experimental evaluation of the safety and biocompatibility of a new antireflux prosthesis

Previous studies have shown that encircling of the esophagogastric junction by a semiabsorbable scarf effectively prevents gastroesophageal reflux, Th e present study was performed to assess the long-term safety and biocompati bility of this type of scarf. The semiabsorbable scarf was implanted into 2 0 dogs either laparoscopically or via laparotomy, Pre- and post-operatively , contrast radiography, esophageal manometry, and upper gastrointestinal en doscopy were performed. No cases of perforation, stricture formation or oth er adverse effects were found after 1 and 2 years. It is concluded that the new type of scarf is without any adverse side-effects. Functional evaluati on in reflux patients appears to be warranted.
