[Stenosis of biliobilary anastomoses and its prevention by ring splinting outside the lumen--results of an animal experiment study].
The causes of the stenosing and their prevention were investigated by means of a ring splinting outside of the lumen in 19 dogs. The dogs were relaparotomised 3, 6, and 12 months after division and reanastomosis of the supra-duodenal choledochus. In contrast to the therapy group (n = 6) the control group shows a statistically significant stenosis of the anastomosis and a dilatation of the proximal bile passages. The stenosis of the anastomosis is caused by a circumscribed cicatricial contraction. This can be held up effectively by a ring splinting outside of the lumen.
