A Case of Stomal Varices Treated Using Sclerotherapy by Direct Puncture

Abstract

An 82-year-old woman with advanced sigmoid colon cancer and rectal cancer underwent laparoscopic Hartmann's surgery. She developed stomal varices due to portal hypertension caused by type C liver cirrhosis four months after the colostomy. She was found to be severely anemic and underwent sclerotherapy by direct puncture twice. We performed sclerotherapy by puncturing the varices directly under ultrasound guidance and obtained a suitable hemostatic effect using an original cylindrical instrument and a balloon to block blood flow. Upon autopsy, pathological findings of stomal varices after sclerotherapy were noted.
