Percutaneous Biliary Interventions for Malignant Biliary Obstruction in Low and Middle-Income Countries: Experiences of Northwestern Nigeria

Abstract

Introduction: Malignant causes of biliary obstruction are common in low and middle-income countries (LMICs) and patients usually present late with unresectable masses. The options for endoscopic and surgical management are scarce in many LMICs. In settings with access to ultrasound and fluoroscopy, percutaneous biliary drainage (PBD) is a promising and minimally invasive option for relieving obstruction and improving the quality of life of these patients. Method: We present a case series of six patients in northwestern Nigeria with cholestatic jaundice caused by malignant biliary obstruction successfully treated by PBD. Results: In five cases, imaging revealed a locally invasive pancreatic head mass causing obstruction. One of the patients had obstruction from biopsy-proven cholangiocarcinoma. Three patients had internal biliary drainage past the obstruction and three patients had only external biliary drainage due to the severity of the obstructions. One patient with internal drainage went on to cholangioplasty and deployment of the balloon-expandable stent over the stenotic segment. All procedures were uncomplicated and patients had a gradual clearance of jaundice and resolution of pruritus. Two of the elderly patients died within six months of the procedure (one from hepatic encephalopathy and the other from stroke). The remaining four survived but were lost to follow-up by 10 months. Conclusions: PBD is a feasible and beneficial option for decompressing malignant biliary obstruction in LMICs.
