70％～90％的胰头癌或壶腹周围癌病人发生梗阻性黄疸,使病情更加恶化,而只有10％～20％病人有手术根治机会。一般认为,对不能根治的病人解除黄疸可采用胆肠吻合术,但并发症率(20％～60％)和死亡率(15～30％)较高。而经PTC或ERCP内置管术再次发生梗阻、黄疸可能性较大(20％～50％)。因此,在选择哪一种方法来有效缓解黄疸尚未达成统一意见。 70% to 90% of pancreatic cancer or periampullary cancer patients have obstructive jaundice, making the condition worse, and only 10% to 20% of patients have the opportunity to surgery. It is generally believed that biliary-enteric anastomosis can be used to relieve jaundice in patients who cannot be cured, but the complication rate (20% to 60%) and mortality (15 to 30%) are higher. The PTC or ERCP built-in tube reoccurrence of obstruction, jaundice is more likely (20% to 50%). Therefore, there is no consensus on which method to use to effectively alleviate the problem.
