嵌頓整復後の鼠径部膀胱ヘルニアに対するTAPP 法施行の 2 例

We present two cases of inguinal bladder hernia diagnosed by preoperative computed tomography (CT)after reduction of incarcerated hernia and treated by transabdominal preperitoneal repair. First case was 72–year–old man with a right inguinal bulge for one year and second case was 86–year–old man with a right inguinal bulge for three years. Both of them presented to our hospital with a sudden pain from a right inguinal region and were diagnosed with incarcerated inguinal hernia. After manual reduction, CT scan revealed a right inguinal hernia and bladder prolapsed in two cases. They were intraoperatively diagnosed with paraperitoneal type of bladder hernia. This case report showed that a preoperative diagnosis of bladder hernia and a laparoscopic approach to Retzius space correctly separated by operator were important in order to prevent bladder injury.
