Retrograde Colonic Stent Implantation Assisted by Percutaneous Colostomy: A Case Report

tion of the colon include surgical and interventional therapy options. With an acceptable risk level, palliative tumor resection is the treatment of choice depending on tumor location, tumor extension, and others. If surgical therapy is not a reasonable option, an alternative option would be the implantation of a stent. Unfortunately, the implantation of a stent through the anus can often be difficult or impossible because of factors such as the inability to pass a guide wire through the lesion due to complete obstruction or obstruction over a long segment, as well as anatomic difficulties such as a severely angulated and “fixed” sigmoid, which prevents advancement to the site of the lesion (1). Although some of these factors can be surmounted, it is not always the case. In this case, inability to pass a guide wire through the lesion was due to a long segmental obstruction, which made stent implantation impossible. However, it was made possible through the anus with the assistance of percutaneous colostomy. This strategy was allowed with the permission of the patient and his family prior to the procedure. The use of percutaneous colostomy for the implantation of a stent has been described in a prior study (2). But, in our case, the use of percutaneous colostomy assisted the implantation of a stent through the anus, with several advantages.
