    Efferent loop stenosis (ELS) can occur after pancreaticoduodenectomy, leading to delayed gastric emptying and requiring careful management.

  • 2

    A 51-year-old woman with ELS post-pancreaticoduodenectomy was treated with endoscopic submucosal dissection and stenting.

  • 3

    Endoscopic submucosal dissection was used to release a mucosal ridge, improving alignment of the efferent loop.

  • 4

    A fully covered self-expanding metal stent was placed to maintain patency, resulting in improved patient symptoms.

  • 5

    This case suggests that modifying loop geometry endoscopically may be a viable alternative to surgical revision for ELS.
