Мinimally invasive stent technologies in hepatopancreatobiliary surgery

Abstract

Aim. To compare the aspects of the use of various stents in hepatopancreatobiliary zone diseases.Materials and methods. We analyzed the experience of using biliary plastic and metal self-expanding stents placed by the antegrade percutaneous (n = 45) or retrograde endoscopic method (n = 160). Pancreatic stenting with 5 Fr plastic stents was performed in 35 patients.Results. Our experience shows the high efficiency of stenting performed by antegrade and endoscopic retrograde access for bile and pancreatic ducts obstruction. Pancreatic stenting is justified in the prevention of acute pancreatitis (in the presence of a risk factor) and in treatment of post-ERCP pancreatitis, as well as in the treatment of acute biliary pancreatitis with impacted stone in papilla Vater.Conclusion. Minimally invasive technologies has a leading role in the treatment of patients with ductal failure of the hepatopancreatobiliary zone. Stenting should be used to prepare for radical surgery or as a final palliative treatment method. A differentiated approach is important in selecting a stent, depending on the specific clinical task. For biliary drainage in patients with obstructive jaundice of various etiologies, it is permissible to use both the retrograde and antegrade stenting. The choice of the decompression method depends on the level of the biliary obstruction, the cause of obstructive jaundice, the technical equipment of the department and the training of specialists in retrograde and (or) antegrade endobiliary technologies. Antegrade access is preferred for proximal obstruction of the bile ducts, retrograde endoscopic access is preferred for distal obstruction.
