[Healing of the anastomosis in various suture techniques in the gastrointestinal tract. Physiology, experimental and clinical results].

New and further development of anastomoses induce new orientation for selection and indication of the several suture procedures in the gastrointestinal tract. Based on the wound healing principles, the different techniques are evaluated experimentally and in clinical tests. The results allow to discriminate indications for the different suture techniques. For the gastrointestinal tract the technique of choice is the serosubmucous single row suture with an absorbable 4.0 monofilament. For the esophagus and rectum, the stapled anastomosis offers more safety and better practicability than manual sutures. Studies have shown comparable results in colonic surgery for compression ring anastomoses. Additional procedures are of minor importance for the safety of anastomoses.
