每天在拉法爾水療中心工作， 接觸到的問題，都和洗腸分不開。 不知道多少次了， creamer我要對無數(shù)多的人回答一個同樣的問題：

　　“我照腸鏡的時候，明明看到自己的大腸內(nèi)壁很干凈，負責(zé)操作腸鏡的醫(yī)生也告訴我，我的大腸很干凈， 我也親眼看到腸壁粉紅色的肌肉了，光光滑滑，為什么還要洗腸creamer？”

　　特別是當(dāng)我跟他們說洗腸每天都要洗，是一定要做的事情的時候， 你可以想見，聽眾的腦海里會有多么大的疑問！

　　我這里有很多醫(yī)學(xué)資料，這些都是公開的醫(yī)學(xué)資料， 是腸鏡過程中的實況影像， 為了照顧到各位的感官感受，我就不在這里把它們放出來了。我要放在這篇文章后面的，是哈佛大學(xué)公共醫(yī)學(xué)院更新發(fā)表的最新《腸鏡準備指南》，這份指南是目前全世界醫(yī)學(xué)界最權(quán)威的怎么樣為成功做腸鏡檢查而做準備的標準，是腸道內(nèi)科醫(yī)生，腸鏡操作技術(shù)人員和所有準備照腸鏡人士的必備手冊。

　　特別應(yīng)該提醒各位的是，這份手冊是為了“成功”做腸鏡檢查的指南，也就是說，如果哪一位要去做腸鏡的朋友沒有嚴格按照這份指南的要求去做準備的話，你的腸鏡檢查就有可能“不成功”。

　　神馬意思？就是說，看不清楚。

　　神馬看不清楚？為神馬看不清楚？我想，再笨的人，我不說，你也知道。

　　我們來看看這份指南是怎么說的：首先， 為腸鏡做準備，就是一個“major inconvenience”, （巨大的不方便），平均要花16個小時，再加上做腸鏡檢查本身的平均3個多小時，最起碼，你生命中的20個小時就沒有了。這20個小時里干什么呢？不舒服，而且是特別不舒服！

　　第一，腸鏡檢查的幾天前，你就要嚴格限制進食，而且不能吃纖維含量高的食物，也就是說，最好只吃白面糊糊，水果蔬菜就別吃了， 肉，就更不用想了。

　　第二，腸鏡檢查的前一天開始，只能流體進食，而且一定要是透明的流體， 還不能喝紅色，藍色或是紫色的液體，在我看來，最好就是只喝白開水了。

　　第三，腸鏡檢查前的至少兩個小時之內(nèi)，連白開水也別喝了，神馬都不能往嘴巴里送！這已經(jīng)夠難受了吧，還沒完，腸鏡檢查的至少前一天開始，就要喝瀉藥，不斷喝瀉藥， 而且有專門的瀉藥，藥效很強，需要醫(yī)生開處方的。然后呢？坐在馬桶上別下來，不停地拉稀，想停都停不??！這份指南里建議，你最好在最后一天開始喝瀉藥的時候，帶著書報雜志，抱著電腦，進到廁所里別出來，因為你沒辦法出來！

　　忍受這么大的痛苦，腸鏡檢查還是有可能“不成功”！為神馬？因為即使是這樣，還是有可能你的大腸被神馬神馬堵著，看不清楚！即使是你和你的大腸在經(jīng)受了這樣一番折騰之后，終于可以讓你對自己的大腸“一見真容”，你想想看，一年365天里面，你有幾天這樣去“折騰”？有沒有哪一個人每天都花上20個小時去這樣“折騰”？

　　那么，洗腸，不是很應(yīng)該做的事情嗎？洗腸，不是每天都應(yīng)該做的事情嗎？這，難道很難理解嗎？

　　下面是哈佛大學(xué)公共醫(yī)學(xué)院最新的《腸鏡準備指南》全文原文：

　　Preparing for a colonoscopy

　　If you shudder at the thought of having a colonoscopy to check for hidden colon cancer, chances are it's the "prep" that's stoking your apprehension. It's certainly a major inconvenience: getting ready for the procedure takes much longer — an average of 16 hours, according to one study — than the three hours or so you'll spend at a medical center the day of your colonoscopy. But what's most off-putting is the purgative part: taking a powerful bowel-clearing substance and coping with the resulting diarrhea.

　　It's worth the hassle. Colonoscopy can spot small colon cancers while they are treatable and before they have spread to other parts of the body. It can also detect and remove polyps, small growths that can develop into colon cancer. Colon and rectal cancers (known together as colorectal cancers) are the third most common type of cancer in men and in women and the second leading cause of cancer-related deaths in the United States.

　　What's involved?

　　Emptying the contents of the colon is a key requirement for a successful colonoscopy. If the bowel prep isn't up to par, polyps and lesions can be missed; the colonoscopy may take longer (increasing the risk of complications); or the whole process may need to be repeated or rescheduled, meaning another round of bowel prep.

　　Different medical centers recommend different ways to prepare the bowel for a colonoscopy. There are two parts: diet and drinking bowel-cleaning liquids. Here are some of the main strategies.

　　Diet

　　A few days before the colonoscopy — Start a eating a low-fiber: no whole grains, nuts, seeds, dried fruit, or raw fruits or vegetables.

　　The day before the colonoscopy — Don't eat solid foods. Instead, consume only clear liquids like clear broth or bouillon, black coffee or tea, clear juice (apple, white grape), clear soft drinks or sports drinks, Jell-O, popsicles, etc.

　　The day of the colonoscopy — As on the previous day, clear liquid foods only. Don't eat or drink anything two hours before the procedure.

　　Bowel prep

　　The afternoon or evening before the colonoscopy, drink a liquid that will trigger bowel-clearing diarrhea. The exact instructions depend on the bowel prep your doctor prefers, the time of your colonoscopy, and any prior experience you've had with colon preps (if one didn't work before, you'll likely be prescribed a different one).

　　The preferred method is known as split dosing. You take half the prep the night before the procedure and the other half about six hours before it. It may clean the colon more thoroughly compared to taking all the prep the day before the procedure.

　　You can read about somecommon bowel preparations approved by the American Gastroenterological Association, American College of Gastroenterology, and American Society for Gastrointestinal Endoscopy. Contact your clinician to discuss the one that is best for you.

　　Tips for a successful colonoscopy prep

　　Preparing for a colonoscopy may be uncomfortable and time-consuming, but it needn't be an ordeal. Here are some things you can do to help it go as smoothly and comfortably as possible:

Make sure you receive your colonoscopy prep instructions well before your procedure date, and read them completely as soon as you get them. This is the time to call your clinician with any questions and to buy the bowel prep she or he has prescribed. Pick up some medicated wipes (for example, Tucks or adult wet wipes with aloe and vitamin E) and a skin-soothing product such as Vaseline or Desitin — you're going to be experiencing high-volume, high-velocity diarrhea.

Arrange for the time and privacy you need to complete the prep with as little stress as possible. Clear your schedule, and be at home on time to start your prep. If you have children or aging parents who need attention, have someone else be available to them while you're indisposed.

Water can get boring, so keep a variety of clear liquids on hand. On the day before your colonoscopy — when you're restricted to clear liquids — you can have popsicles, Jell-O, clear broth, coffee or tea (without milk or creamer), soft drinks, Italian ice, or Gatorade. But take nothing with red, blue, or purple dye. Drink extra liquids before, during, and after your bowel prep (usually until a few hours before your procedure), as well as after your colonoscopy.

To make a bad-tasting liquid prep like magnesium citrate easier to swallow, try one or more of the following if it doesn't come flavored: add some Crystal Light or Kool-Aid powder (again, not red, blue, or purple); add some ginger or lime; drink it chilled; drink it through a straw placed far back on your tongue; hold your nose and drink it as quickly as possible; quickly suck on a lemon slice after you finish each glass; hold a lemon or lime under your nose while you drink; suck on a hard candy after each glass.

Wear loose clothing, and stay near the bathroom. Better yet, once the preparation starts to work, stay in the bathroom — because when the urge hits, it's hard to hold back. Consider setting up shop near the toilet with music, your laptop, magazines, or books.
