[Incisional hernia after surgical laparoscopy: a case of hepatic ligament incarceration and review of the literature].

The authors report a case of incisonal hernia occurring 5 years after laparoscopic treatment of extra-uterine pregnancy. This involved incarceration of the hepatic suspensor ligament during insertion of a 10 mm umbilical trocard. Laparoscopy permitted diagnosis and treatment of the hernia. Parietal complications after laparoscopy usually concern epigastric vascular lesions, infections at trocard sites, and residual abdominal wall pain. Incisonal umbilical and extra-umbilical hernias, described for the first time in 1968, are highly unusual complications, with an incidence of 21/100,000 in the Mintz study. The hernia sac usually contains omentum or small intestine. The present observation alems to be the first case of incarceration of the hepatic suspensor ligament in an umbilical trocard. This observation is remarkable not only for the hernia sac contents but also for the delay between laparoscopy and the occurrence of the umbilical hernia.
