The aim of this study was to explore the safety and efficacy of a novel mini-open sublay hernioplasty with D10 mesh for primary lumbar hernias.
This retrospective study included 48 patients with primary lumbar hernias who underwent mini-open sublay hernioplasty with D10 mesh from January 2015 to January 2022 in our hospital. Observation indicators were intraoperative measured diameter of hernia ring defect, operation time, length of hospital stay, postoperative follow-up, complications, postoperative visual analog scale (VAS) score, chronic pain.
The operations were completed successfully in all 48 cases. The mean diameter of hernia ring was 2.66 ± 0.57 cm (range 1.5-3.0 cm), the mean operation time was 41.54 ± 13.21 min (range 25-70 min), the intraoperative blood loss was 9.89 ± 6.16 ml (range 5-30 ml), and the mean hospital stay was 3.14 ± 1.53 days (range 1-6 days). The mean preoperative and postoperative VAS scores at 24 h were 0.29 ± 0.53 (range 0-2) and 2.52 ± 0.61 (range 2-6), respectively. All cases were followed-up for 53.4 ± 24.3 months (range 12-96 months) without seroma, hematoma, incision or mesh infection, recurrence, and obvious chronic pain.
A novel mini-open sublay hernioplasty with D10 mesh for primary lumbar hernias is safe and feasible. Its efficacy in the short term is favorable.

Lumbar hernias are quite rare, even more so when primary or of spontaneous nature. These defects in the lumbar region demand a comprehensive knowledge of the anatomy of the lateral abdominal wall and paraspinal muscles. Given the proximity of bone structures, they can pose a surgical challenge when trying to achieve an ideal dissection and appropriate mesh overlap. The authors report the case of a primary Petit\'s hernia that underwent an open anterior surgical approach with the use of a preperitoneal mesh. In addition to the described surgical technique, the article also aims to detail the diagnosis and anatomic classification of this rare pathology.

Retroperitoneal lumbar hernias are a rare entity. Atraumatic posterior perirenal hernias are an exceptionally rare form of retroperitoneal lumbar hernias. Because of their infrequency, there are no standardized methods of surgical care for the treatment of atraumatic (primary spontaneous) posterior perirenal hernias. This report documents the finding and management of an atraumatic posterior perirenal lumbar hernia in a 69-year-old female.

BACKGROUND: Posterior abdominal wall hernias are rare, mainly post traumatic or post-operative. This case is particular first by its mechanism, it is a primary lumbar hernia and secondly it is a concomitant hernia of the Jean Louis Petit triangle and the Grynfeltt triangle.
METHODS: The patient was a 67 years old man, a former farmer. He complaint of a painful tumefaction on his back evolving for the last 2 years. After clinical examination, a diagnosis of lumbar hernia was retained. The CT scan which is the gold standard was not performed due to financial limitations. An hernioplasty with a porcine collagen mesh was done, in per operative we found a Jean Louis Petit hernia and a Grynfeltt-Lesshaft hernia. Any post-operative complications.
CONCLUSIONS: Lumbar hernia is not a common diagnosis, and most of time is misdiagnosed. Acquired primary lumbar hernia can be due to profession involving lumbar constraints leading to the weakness of muscles. This was the case of our patient. Another particularity was the double hernia, the upper and lower lumbar triangles. We already know the impact of his profession and may be 20 years of this leaded to the double hernia? An hernioplasty in open surgery was proposed for multiples reasons: the age of the patient, the weakness of the muscle, a large exploration of the hernia, to reinforce the posterior lumbar wall and to prevent a recidivism.
CONCLUSIONS: Jean Louis Petit and Grynfeltt-Lesshaft hernias are very uncommon. Few cases have been reported.

Primary lumbar hernias are rarest form of hernias as compared to other ventral abdominal wall hernias. Only scattered reports of hernias of both superior and inferior lumbar triangles have appeared in both the English and foreign literature. There are only about 300 cases of primary lumbar hernia being reported. Being a rare entity, it had always posed diagnostic and treatment dilemma to the surgeons. The diagnosis requires imaging studies in such cases. Treatment of lumbar hernia is always surgical and requires prosthetic reinforcement for the best result. We are reporting here a case of primary lumbar hernia of the superior lumbar triangle with a successful repair with a sheet of polypropylene mesh. In our case, acquired primary lumbar hernia was emerging from superior lumbar triangle, associated with congenital right scoliosis, which is a rare occurrence.
