[Postoperative ventral hernias]. 
An analysis of the observation of 107 patients has shown the etiological factors of the appearance of postoperative ventral hernias to be varied: lowered resistance of the patient's organism to infection, choice of an irrational operative access, insufficient hemostasis, carelessness in handling with tissues during operation, severe concomitant diseases, erroneously chosen method of anesthesia.  Peridural anesthesia is recommended for the operative treatment of ventral hernias.
