Accidental peritoneum-cutaneous fistula after insufflation of preoperative progressive pneumoperitoneum in a large incisional hernia with loss of domain.

Preoperative progressive pneumoperitoneum has represented an important advancement in achieving the reintroduction of large herniated volumes into the abdominal cavity. However, this technique is not free of complications. We present a case of a man in his 70s with an accidental peritoneal-cutaneous fistula, secondary to the excessive pressure of the pneumoperitoneum, during the preparation of a large incisional hernia with loss of domain intervention.
