Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is an RNA virus responsible for coronavirus disease 2019 (COVID-19).
The virus enters cells via the angiotensin-converting enzyme 2 ...receptor, which is present in enterocytes in the ileum and colon.
Gastrointestinal (GI) manifestations include diarrhea, nausea, vomiting, and abdominal pain, and the prevalence of GI symptoms varies greatly, with a range between 2% and 57%.
In addition, abnormal liver chemistries are reported commonly.
As a medical center at the forefront of the early epidemic in the United States, we seek to contribute to the growing body of literature that outlines the gastrointestinal and hepatic manifestations of COVID-19.
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™. We aim to contribute to the limited body of literature that describes endoscopic repair of duodenal perforation secondary to biliary stent migration using through-the-scope endoclips.
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. Metastasis to the duodenum, however, is exceedingly rare, with very few cases of stomach or duodenal involvement described in the literature. We report the case of a patient with stage IV pulmonary squamous cell carcinoma metastasizing to the duodenum with an uncommon presentation to add to the paucity of literature available regarding this rare finding.
