Five-Millimeter Balloon Trocar Site Herniation: Report of Two Cases and Review of Literature

Trocar site herniation is a well-known potential complication of minimally invasive surgery. We present the cases of two herniations after use of 5-mm non-bladed balloon trocars. In both patients, surgical management was required, with no subsequent sequelae to date. The hernias were attributed to excessive fascial stretching and compression by the balloon. We recommend full-thickness closure of 5-mm ports if a balloon is used or if there was extensive intraoperative manipulation.
