Laparoscopic repair of sciatic hernia recognizing the ureterohypogastric nerve fascia and vesicohypogastric fascia: a case report

Abstract

Abstract Background Sciatic hernias are rare pelvic floor hernias that occur through the sciatic foramen and often present as abdominal or pelvic pain, particularly in women. Historically, they were repaired using an open approach, with limited reports on their laparoscopic treatment. Case presentation Here we present the case of an 85-year-old woman who had repeated abdominal pain and was referred to our hospital for sciatic hernia surgery after conservative treatment. We laparoscopically observed the deep pelvis and identified the right sciatic hernia. When an extraperitoneal space was dissected, an ureterohypogastric nerve fascia (UNF) and a vesicohypogastric fascia (VF) were identified. Moreover, the maneuver to mobilize the fasciae inside from the pelvic wall made it possible to separate the ureter and urinary bladder, which might have otherwise incarcerated in the hernia. We repaired the defect of the sciatic foramen with a mesh plug and patch. The patient had an uneventful recovery, and the absence of sciatic herniation recurrence was confirmed 1 year after surgery. Conclusion A laparoscopic repair of a sciatic hernia could permit detailed non-invasive observations of the deep pelvis and be performed effectively by recognizing an UNF and a VF located near the sciatic foramen.
