There are three types of lumbar hernia: congenital, acquired, and incisional hernias. Acquired hernia can appear in two forms: the inferior (Petit) type and the superior type, first described by Grynfeltt in 1866. We report endoscopic extraperitoneal repair of a Grynfeltt hernia. A 46-year-old woman presented with a painful swelling in the left lumbar region that had caused her increasing discomfort. The diagnosis of Grynfeltt's hernia was made, and she underwent surgery. With the patient in a left-side decubitus position, access to the extraperitoneal space was gained by inserting a 10-mm inflatable balloon trocar just anteriorly to the midaxillary line between the 12th rib and the superior iliac crest through a muscle-splitting incision into the extraperitoneal space. After the balloon trocar had been removed a blunt-tip trocar was inserted. Using two 5-mm trocars, one above and another below the 10-mm port in the midaxillary line, the hernia could be reduced. A polypropylene mesh graft was introduced through the 10-mm trocar and tacked with spiral tackers. The patient could be discharged the next day after requiring only minimal analgesics. At this writing, 2 (1/2) years after the operation, there is no sign of recurrence. This Grynfeltt hernia could safely be treated using the extraperitoneal approach, which obviates opening and closing the peritoneum, thereby reducing operative time and possibly postoperative complications.
