Primary Endoscopic Closure of Duodenal Perforation Secondary to Biliary Stent Migration: A Case Report and Review of the Literature.

Duodenal perforation due to biliary stent migration is rare, and it often requires surgical repair; however, endoscopic closure has recently become a viable option in the appropriate patients. We present the case of a 79-year-old female who underwent biliary stent placement for a common bile duct stricture, who subsequently was found to have a duodenal wall perforation secondary to stent migration. The stent was extracted endoscopically with successful defect closure using a ConMed repositional DuraClip™.

Rare Case of Duodenal Metastasis From Pulmonary Squamous Cell Carcinoma.

Pulmonary squamous cell carcinoma is the second most common non-small cell malignancy of the lung. It commonly metastasizes to the adrenal glands, bone, liver, brain, and kidneys. Most occurrences of metastatic squamous cell carcinoma involving the gastrointestinal tract originate from primary lung tumors.
