Mainz pouch with appendix-umbilical stoma using catheterizable conduit elongated with continuous cecal segment: a case report

Abstract

53歳男.8cmの虫垂の遠位側3cmに強い炎症性狭窄が術中に判明した症例で, 盲腸部をGIA自動縫合器を用いて管状化することにより, 虫垂道尿管路の延長(4cmの延長で径9cm)を図った.得られた遊離虫垂をMitrofanoff法でパウチ吻合を行い, 盲腸即断端を臍窩と吻合した.術後経過は順調で, 軽度ストーマ狭窄はあるもののブジーのみで軽快し, 良好な結果が得られた

The Mainz pouch with appendix-umbilical stoma is a very stable method for continent, self-catheterizable urinary reservoir in the presence of a healthy appendix. If the appendix is too short or an unexpected stenosis is seen at its distal portion, the elongation of the conduit using a part of the cecum and the implantation of the conduit to the pouch by the Mitrofanoff method can be a good alternative procedure. We herein report our experience in a 53-year-old male with high grade, invasive bladder tumor, who underwent cystourethrectomy and appendix Mainz pouch operation using the above technique.
