Postoperative integrity of anastomoses in abdominal surgery is fundamental to secure a good result in reconstruction operations which involve the resection of several parts of the alimentary tract where afflicted by various pathologies. The Authors study this problem with an experimental work. These experiments illustrate the resistance of STPU stapler sutures and their capability to overcome pressures which are above physiological level; the application of histoacryl glue strengthens even more the sutured area increasing the level of pressure resistance. This procedure allows the patient to drink sooner and avoids the perforation of stomata which means a reduction of the patient's discomfort and a reduction of his confinement to bed.
