Incisional hernia, a rare complication of the anterolateral transpsoas approach.

Introduction: Anterolateral transpsoas approach is considered as safe access to the retroperitoneum with low risk of complications. The most frequent described complications due to this approach were nerve, bowel, urethral and kidney injury. An incisional hernia is a rare complication in anterolateral approach, as a result of a nonhealing surgical wound or late disruption of the fascia; it occurs in 1% of the incisions after primary closure.
Case Description: We report a 75-year-old woman who underwent spinal surgery with a double approach, consisting of an anterolateral transpsoas approach and posterior lumbar approach. Two months post-surgery, the patient developed a lateral abdominal tumor at the surgical site.
Conclusion: To prevent incisional hernia, a meticulous dissection must be performed to avoid muscle denervation and weakening of the abdominal wall, as well as proper repair of the fascia its critical to ensure an adequate closure of the wound.
