Treatment of efferent loop syndrome after pancreatoduodenectomy with a fully covered self‐expandable metal stent: A case report

Efferent loop syndrome is a very rare complication following pancreatoduodenectomy. The treatment of efferent loop syndrome varies depending on the cause of the syndrome. Conservative treatment methods, including nasogastric drainage and enteral nutrition, are adopted that are effective in most of patients; however, surgical treatment is usually required in patients with complete loop obstruction. Herein, we report a case of severe efferent loop obstruction that occurred after pancreatoduodenectomy, which was refractory to conservative treatment and successfully resolved by insertion of a fully covered self‐expandable metal stent.
