肛門管癌に対し腹腔鏡下骨盤内臓器全摘術を施行した1例

A 83-year-old man with chief complaints of anal pain and disability to take a seat was diagnosed as anal cancer (tub1) and visited our hospital. CT and MRI examinations show tumor, from anal canal to lower rectum, with invasion to levator ani muscle, external anal sphincter and prostate. Furthermore three lung metastases in the upper lobes of the lung were suspected. We diagnosed to be resectable lung metastases, and performed laparoscopic total pelvic exenteration with lymph node dissection D2. An ileal conduit was constructed extracorporeally via an umbilical incision. There were no conversion to laparotomy and intraoperative complications. The total operating time was 424 minutes, with an estimated blood loss of 140 ml. Postoperative complication was only ileus treated conservatively. Preoperative chief complaints promptly disappeared after operation. Opportunities to treat pulmonary metastasis of colorectal cancer have been increasing with a rise in primary diseases and advances in chemotherapy. To our knowledge, this is the first report of palliative laparoscopic total pelvic exenteration for advanced anal cancer with distant metastasis.
