[Comparative study on anastomotic surfaces obtained after using mechanical suture in digestive surgery (author's transl)].

The authors studied the theoretical values of the anastomotic surfaces obtained after using mechanical suture clips of American origin in digestive surgery. The EEA clip enables circular anastomoses to be obtained immediately. The anastomotic surface is defined by the capsule used, whatever the diameter of the digestive tube. The TA clip determined, by using the triangulation principle, anastomoses that have a tendency to become circular. The anastomotic surface varies as a function of the digestive tube diameter and may reach much higher values. With the GIA clip, laterolateral anastomoses can be obtained which are complete by closure of the outgoing orifice of the apparatus. Large variations in anastomosis surface are obtained according to the method used to close the orifice. This study supplies a new aspect of mechanical sutures. It gives the surgeons, who agrees with this suturing method, a supplementary element of choice for the anastomotic procedure.
