胰腺外分泌受下列因素的调节:交感、副交感神经、多种胃肠道激素、局部释放起作用的神经递质和胰-肠反射。胰腺外分泌有两种类型:1.导管型(对胰泌素起反应),分泌富含重碳酸盐的水样液体;2.腺泡型(对CCK-PZ起反应),分泌富含蛋白质的消化酶,包括淀粉酶、蛋白酶和脂肪酶。理论上,下列情况能引起胰原性消化不良状态:1,胰腺分泌完全缺乏或从肠道丧失;2,重碳酸盐分泌不足或不足以中和高胃酸;3,胰消化酶分泌不足。因此,胰原性消化紊乱可由高胃酸分泌状态、胰腺切除、肠旁路手术和胰腺的
Pancreatic exocrine regulation by the following factors: sympathetic, parasympathetic, a variety of gastrointestinal hormones, local release of neurotransmitters and pancreatic-intestinal reflex. There are two types of pancreatic exocrine: 1. a catheter type (which responds to secretin) that secretes a bicarbonate-rich water-like fluid; 2. an alveolus (which reacts with CCK-PZ), secretes protein-rich Digestive enzymes, including amylases, proteases and lipases. In theory, the following conditions can cause pancreatogenic dyspepsia: 1, the complete lack of pancreatic secretion or loss from the intestine; 2, inadequate or insufficient bicarbonate neutralization of high gastric acid; 3, inadequate secretion of pancreatic digestive enzymes. Thus, pancreatogenic digestive disorders can be caused by a high gastric acid secretion status, pancreatectomy, intestinal bypass surgery, and pancreatic
