ARTICLE HIGHLIGHTS
Case characteristics

The patient with a bare metal stent (BMS) in the common bile duct (CBD) and self-expanding metal stent (SEMS) in the duodenum presented with worsening jaundice symptoms.

Clinical diagnosis

On esophagogastroduodenoscopy (EGD) patient was found to have gastric outlet obstruction (GOO) type II and worsening jaundice due mass obstructing the CBD.

Differential diagnosis

Pancreatic, duodenal or ampullary mass.

Laboratory diagnosis

Main laboratory testing for a biliary and duodenal obstructing mass would be a tissue biopsy obtained via endoscopic guided technique.

Imaging diagnosis

CT scan of the abdomen was used initially to find GOO followed by esophagogastroduodenoscopy (EGD).

Pathological diagnosis

Adenocarcinoma of the pancreas was found on biopsy.

Treatment

Covered metal stent (CMS) was placed into the previous BMS within the CBD through the already existing duodenal SEMS with relief of jaundice symptoms.

Related reports

To our knowledge other case reports don’t have concomitant BMS in the CBD and SEMS in the duodenum while getting CMS in the CBD stent.

Experiences and lessons

Even though accessing the papilla through an already existing duodenal SEMS and CBD BMS may be difficult, endoscopists can try cannulating the CBD to relieve patient’s obstructive biliary symptoms, and if need deploy another stent.
