Sciatic hernia: repair after recurrence.

Sciatic hernia is a rare pelvic floor hernia. A variety of treatment modalities were proposed, but a guideline is lacking although a mesh-based tension-free repair may be preferred. A 67-year-old woman with an uncomplicated sciatic hernia received primarily closing of the hernia orifice that was covered with a preperitoneal mesh in March 2019. Six months later, she developed a clinical and radiographical recurrence requiring remedial surgery. Due to the previous mesh fixation, the preperitoneal plane was obliterated. Therefore, the pouch of Douglas was closed, leaving the hernia sac in place, by folding two opposing peritoneal layers and covering it with a Ventralight ST mesh. After 9 months, the hernia had not recurred and the patient was symptom-free. It is concluded that recurrent sciatic hernia may be treated by obliterating the Douglas pouch and subsequent mesh coverage.
