Clinical Case Summary
Introduction: Locally advanced pancreatic tumors can lead to both biliary and duodenal obstruction by invasion or compression. Quality of life is severely affected if obstruction occurs: jaundice, emesis and pain can become invalidating and patients become too frail for palliative chemotherapy and are sometimes declared unfit even for derivative surgery. Recently, endoscopic techniques under EUS or ERCP guidance are being used to create biliodigestive and enteral anastomoses.
Clinical case: A 75-year-old female was diagnosed with locally advanced pancreatic head adenocarcinoma in January 2024. The tumor was declared unresectable and chemotherapy was initiated. A plastic stent was inserted into the main biliary duct (MBD) to ensure biliary drainage. In May 2024, she presented with cholangitis and emesis. EGD revealed duodenal stenosis and ERCP failed due to tumor infiltration. A combined endoscopic approach was performed: EUS-guided hepatico-gastrostomy (EHG) for biliary drainage and EUS-guided gastro-enterostomy using a lumen-apposing metal stent (LAMS). In July 2024, the plastic stent was removed, and in August 2024, two fully covered 60 x 10 mm SEMS were inserted antegrade through the EHG into the MBD to improve patency. At 11 months post-intervention, the patient returned for routine reassessment, declaring good clinical performance: she remained asymptomatic, with routine blood tests, including bilirubin levels within normal range and with all stents patent and correctly positioned (confirmed radiologically and endoscopically). The patient was able to maintain oral intake and continue chemotherapy. No late adverse events were noted.
Conclusion: This case demonstrates the long-term clinical and technical success of a staged endoscopic triple bypass for the management of complex biliary and duodenal obstruction due to unresectable pancreatic cancer. The approach was minimally invasive, well tolerated and remarkably improved the patient's quality of life.
