Lindquester WS, et al. - A comparative analysis of the long-term clinical effectiveness before and after implementation of a structured protocol for percutaneous drainage of benign anastomotic biliary strictures was conducted. Irrespective of the presence of a structured protocol, percutaneous drainage and management of benign biliary anastomotic strictures proved to be an effective treatment. No notable benefit was yielded in terms of avoidance of surgical revision. Yet, an increase in the time until surgical revision and patency rates with the protocol was demonstrated. The findings exhibited a connection between larger maximum drain size with a better outcome.
