Due to the rarity of Grynfelt hernia, there is no standardized surgical technique.

From April 2010 to September 2017, 12 cases of primary superior lumbar hernia (Grynfelt hernia) were identified through medical records reviewing and included in our study. Perioperative data, surgical outcomes, and long-term follow-up results were retrospectively analysed.

Male/female ratio of patients was 1:1, with age 69.5 (62, 74.5) [median (25 percentile, 75 percentile)] years old. Right/left side ratio of lumbar hernia was 9/3. The in-hospital duration was 7 (5, 8) days. The surgical duration was 35 (30, 50) minutes. The defect size was 2.1 (1.5, 3) cm in diameter. The discharge of the patient was on 3 (2, 4) post-operative day (POD). The meshes used were: MK5816 (10), MK5810 (1), and UHS (1). There was only 1 case of postoperative complication where the patient was admitted in intensive care unit (ICU) due to hypoxemia. Morbidity, mortality, and recurrence cases were null.

Our study indicates that open surgery with mesh implantation is a reliable way for the management of primary superior lumbar hernia.
