Direct percutaneous drainage of an obstructed afferent loop.

Afferent loop obstruction is an uncommon complication of Billroth II gastroenterostomy. The treatment of afferent loop obstruction has traditionally been surgical. Recently, percutaneous drainage of obstructed afferent loops using a transhepatic approach was described [1]. In the case presented in this report, a direct percutaneous approach to afferent loop drainage was used successfully. To the best of our knowledge, this technique has not been reported before.
