Summary
This study shows that combined endoscopic stenting of malignant biliary and duodenal strictures using self-expandable metal stents (SEMS) is feasible. The procedure is safe and effective for palliation, with high success rates for biliary stenting through duodenal SEMS.
Area of Science:
- Gastroenterology
- Interventional Endoscopy
- Oncology
Background:
- Malignant biliary and duodenal strictures often require palliative stenting.
- Combined stenting presents technical challenges.
- Self-expandable metal stents (SEMS) are a common treatment modality.
Purpose of the Study:
- To evaluate the technical feasibility of an endoscopic approach for combined biliary and duodenal stenting.
- To assess the safety and efficacy of this combined SEMS insertion technique.
Main Methods:
- Prospective follow-up of consecutive patients undergoing combined gastroduodenal and biliary stenting.
- Recording of patient demographics, stricture characteristics, procedural success, complications, and survival.
- Categorization of patients based on the timing of biliary and duodenal obstruction.
Main Results:
- 64 patients underwent successful duodenal SEMS deployment.
- Combined stenting success rates were 100% (group 1), 86% (group 2), and 100% (group 3).
- Early and late complication rates were 6% and 16%, respectively; median survival was 81 days.
Conclusions:
- Combined endoscopic SEMS insertion for malignant biliary and duodenal obstruction is safe and effective for palliation.
- Biliary stenting through the duodenal SEMS mesh is technically feasible with high success rates.

Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:
