Previous studies have shown that encircling of the esophagogastric junction by a semiabsorbable scarf effectively prevents gastroesophageal reflux. The present study was performed to assess the long-term safety and biocompatibility of this type of scarf. The semiabsorbable scarf was implanted into 20 dogs either laparoscopically or via laparotomy. Pre- and post-operatively, contrast radiography, esophageal manometry, and upper gastrointestinal endoscopy were performed. No cases of perforation, stricture formation or other 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 evaluation in reflux patients appears to be warranted.
