A lumbar abdominal wall hernia is a protrusion of intraperitoneal or extraperitoneal contents through a weakness in the posterior abdominal wall, usually through the superior or inferior lumbar triangle. Due to its rare occurrence, adequate knowledge of anatomy and methods for optimal diagnosis and treatment might be lacking with many surgeons. We believe a clear understanding of anatomy, a narrative review of the literature and a pragmatic proposal for a step-by-step approach for treatment will be helpful for physicians and surgeons confronted with this condition. We describe the anatomy of this condition and discuss the scarce literature on this topic concerning optimal diagnosis and treatment. Thereafter, we propose a step-by-step approach for a surgical technique supported by intraoperative images to treat this condition safely and prevent potential pitfalls. We believe this approach offers a technically easy way to perform effective reinforcement of the lumbar abdominal wall, offering a low recurrence rate and preventing important complications. After meticulously reading this manuscript and carefully following the suggested approach, any surgeon that is reasonably proficient in minimally invasive abdominal wall surgery (though likely not in lumbar hernia surgery), should be able to treat this condition safely and effectively. This manuscript cannot replace adequate training by an expert surgeon. However, we believe this condition occurs so infrequently that there is likely to be a lack of real experts. This manuscript could help guide the surgeon in understanding anatomy and performing better and safer surgery.
