Superior lumbar hernia after gastrectomy repaired via an open approach in the prone position: A case report

Introduction: Lumbar hernia is a rare hernia in the posterolateral abdominal wall and only about 310 cases are known to have been reported to date. Laparoscopic hernioplasty is a common surgical approach but is unsuitable for patients who have previously undergone laparotomy and are expected to have extensive visceral adhesions.

Presentation of case: An 84-year-old woman who had undergone an open distal gastrectomy was referred to our hospital with an enlarging but easily reducible bulge in the right upper back. On computed tomography, the hernial orifice was located in the lateral side of the right quadratus lumborum under the costal arch. The bulge was diagnosed as a superior lumbar hernia. We performed an open hernioplasty in the prone position to avoid internal visceral adhesions. The hernia sac was detected in the latissimus dorsi in the back, and was found to contain the ileocecum, which was rigidly adherent to the sac. Hernioplasty was performed by inserting polypropylene mesh between Zuckerkandl's fascia and the internal oblique.

Discussion: Mechanical ileus after open distal gastrectomy is common complication and sometimes position was simple procedure without the influence of visceral adhesion and easily reinforced by underlay mesh.

Conclusions: Open hernioplasty in the prone position using a mesh underlay is an optional approach in a patient with a superior lumbar hernia after gastrectomy.
