[Transanal compression anastomosis in the lower rectum with a biofragmentable anastomosis ring (Valtrac). Surgical technique and initial clinical experiences].

In a pilot clinical study the practicability and postoperative course were investigated after compression anastomoses in the lower rectum using a new Valtrac application device. In all 15 patients the transanal compression anastomosis using a biofragmentable anastomosis ring was possible. Most difficult was the creation of the distal purse-string suture to fix the Valtrac ring in the rectum. Using this device the possible distal margin of the anastomosis is about two centimeters to the anal canal. There were no complications with clinical relevance for the postoperative course. Radiological leakages on day 8-10 postoperatively occurred in three patients. The new transanal application device for anastomoses in the lower rectum is a possible alternative to standard anastomoses procedure. Clinical studies hat to demonstrate a possible advantage in patients outcome after using this new operative technique in the lower rectum.
