Incisional hernia occurred in a patient after laparoscopic hysterectomy. The greater omentum was incarcerated in the tract of the suprapubic trocar (12 mm diameter). Diagnosis and treatment were performed during a second laparoscopy procedure. The greater number of trocar instruments and their larger diameter increases the risk of parietal morbidity after laparoscopic procedures. Elective closures of trocar incisions is recommended when exceeding 10 mm. Prevention of extra-umbilical incisional hernias and dehiscences appears to be more effective when suture is performed under laparoscopic vision with the trocar inserted. Both the aponevrosis and the peritoneal membrane should be treated.
