Abstract:
Objective To retrospectively analyze the complications and management of complications during percutaneous implementation of biliary stents in 17 patients. Methods Percutaneous biliary drainage and implementation of biliary stents for malignant biliary obstruction under fluoroscopic guidance was performed in 64 patients. 17 cases developed complications. Bradycardia and hypotension was seen in 5 cases, slipping of the stent into the duodenum in 1, bile duct perforation in 2, the fine guidewire broken in the hepatic parenchyma in 2, malposition of the stent in 3, hepato renal failure leading to hemorrhage in 2, exchanging guidewire broken in the duodenum in 1, and balloon broken leading to stent dislocation in 1, respectively. Results Bradycardia and hypotension in the 5 cases was treated medically and the procedure was interrupted. Slipping of the stent into the duodenum was passed off spontaneously. Broken of the fine guidewire in the liver did not present any complaints until the death of the patients. Perforation of bile duct was treated conservatively with a clinical successful outcome. Malposition of the stent was treated by reimplementation of shorter stents. The broken exchanging guidewire in the duodenum during implementation was removed with the gastroscope. The hepato renal failure leading to hemorrhage had poor prognosis. The broken balloon caused stent dislocation was treated by reimplementation of stent. Conclusion Percutaneous implementation of stent is effective and safe for elderly patients with proximal stenosis of the biliary tract. However, one must be very careful to avoid the complications.
