Stent versus surgery.

Following the introduction of percutaneous and endoscopic biliary drainage there has been an ongoing debate about the indications and outcomes of endoscopic versus surgical drainage in a variety of bilio-pancreatic disorders. The evidence-based literature concerning four different areas of pancreatobiliary diseases have been reviewed. Preoperative endoscopic biliary drainage in patients with obstructive jaundice should not be used routinely but only in selected patients. For patients with biliary leakage and bile duct strictures after a laparoscopic cholecystectomy, endoscopic stent therapy might be first choice and surgery should be used for failures of endoscopic treatment. Surgery is the treatment of choice after transection of the bile duct (the major bile duct injuries). The majority of patients with obstructive jaundice due to advanced pancreatic cancer will undergo endoscopic drainage but for relatively fit patients with a prognosis of more than 6 months, surgical drainage or even palliative resection might be considered. For patients with persistent pain due to chronic pancreatitis surgical drainage combined with limited pancreatic head resection might be first choice for pain relief. Most importantly, the management of patients with these pancreatobiliary diseases should be performed by a multidisciplinary HPB approach and teamwork consisting of gastroenterologists, radiologists and surgeons.
