十二指肠开关

What is Duodenal Switch Surgery?

Duodenal weight loss surgery helps shorten the path food follows through the small intestine. In turn, this reduces the time your body has to absorb calories from the food you eat to help you lose weight.

这种类型的手术是微创的，但是您的医生必须检查胃袖的状况，因为只有在胃袖和开放到十二指肠健康的情况下才能进行手术。

手术包括三个步骤:

1. 外科医生在两个地方切断了小肠：横跨幽门的十二指肠，大约进入肠道的一半。这留下了两个小肠道，每部分长约8-10英尺。
2. Surgeon sews and staples the top of the first section of intestine closed and attaches the bottom to the second section, about 3 feet from where the small intestine meets the large intestine.
3. When the surgeon attaches the second part of the small intestine to the pylorus where the duodenum used to be, the duodenal switch is complete.

手术完成后，胃中的食物现在将穿过约10英尺的小肠而不是20英尺，从而减少了人体吸收卡路里和营养所需的时间，从而促使体重减轻。

Pros and Cons of Duodenal Switch Surgery

Duodenal switch surgery has several advantages to help you lose weight and stay healthy. The pros include:

• 对具有很高体重指数（BMI）和严重或多重健康风险的患者最有帮助
• The ability to eat larger meals than with other, purely restrictive procedures, which means a greater feeling of satisfaction
• Can lose up to 70 percent excess weight

While duodenal switch surgery can be right for you, it also comes with some things to consider:

• 您的饮食将需要在您的余生中发生重大变化。
• You may experience nausea, vomiting and discomfort from food that you could once eat without a problem.
• Sugars and sweets can trigger dumping syndrome, which includes symptoms of nausea, weakness, sweating, anxiety and heart palpitations after eating. While these are not usually health risks, they can be uncomfortable or painful.
• Bypassing a large part of your intestine limits your body’s absorption of important nutrients, vitamins and minerals, such as protein, fat-soluble vitamins (A, E, D and K), iron, calcium, vitamin B-12 and folic acid. Daily supplements will need to be taken.
• Overeating can stretch the stomach pouch.

在十二指肠开关手术方面，患者应与医生紧密合作，以监测蛋白质营养不良，贫血和骨骼疾病。

重要的是要注意，吸烟者不是十二指肠开关手术的候选者，因为吸烟使患者患有感染，血凝块，缓慢愈合和其他威胁生命的并发症的风险增加。
