Guest guest Posted November 6, 2005 Report Share Posted November 6, 2005 There is really only one good test for the presence of gallstones, but it only comes at great cost (Exploratory Surgery) or, too late (Post Mortem Exam). In either case, you are getting DIRECT VISUAL EXAMINATION which is pretty dang accurate. Most doctors are quite happy to perform either of these procedures on you, sometimes the former leading to the latter. Of course, that does kill the cash cow which they do try to avoid. They can also perform another invasive procedure, the ERCP, wherein an endoscope is crammed down your gullet and redirected (hopefully) up the bile duct into the GB. This is done under mild sedation (which has risks) or light anesthesia (riskier) and has a fair risk of perforation or rupture of the intestine, bile duct or GB (they told me I had a 5-10% chance of a perforation--I was lucky and I waived the procedure only to be " fired " as a patient by my gastroenterologist over it) . However, it is an amazing bit of technology in that in addition to the camera on board, it has optional " grabbers " that can snatch a stone out of a stuck place, or at least break it up. That is, if they don't punch a hole in your already weakened GI tract. Still beats the hell out of an exploratory laparotomy! Gastroenterologists LOVE this little money-maker and will try every trick in the book to get you to sign the release form. Almost all other forms of " looking into the body " have glaring inadequacies... 1) ULTRASOUND- provides only blurry, shadowy images and there is the serious problem of overlapping tissues including intestines, ingesta and other organs. Cholesterol stones have virtually the exact composition of liquid bile so they don't stand out at all. A good reader of ultrasound can pick out a thickened gall bladder or ductal wall and it may even show distention of the duct if the stone is lodged inside. One good thing, it's virtually non-toxic since it consists mainly of sound waves, plus it's cheap and low tech. 2) CONVENTIONAL X-RAYS- Have most of the problems as mentioned above, not the least of which is shooting through 12-24' of body mass including the vertebral spine. X-rays, and all forms of ionizing radiation are very hazardous to the body (especially breasts, uterus, eggs and developing babies)! Virtually worthless when diagnosing gallstone issues and the technique itself is on the way to the museum of medical history. The only way to make it somewhat diagnostic is to inject radiopaque dye (CONTRAST MEDIA) into the bile duct and shoot pictures as it moves along. This can be done with FLOROSCOPY e.g. a continual beam of X-rays that transfer to a videotape of the dye study. Creates much more radiation plus it's invasive and dangerous to get the dye into the bile duct. ~~~~~~~~~~~~~~~~~~~~~~~ Sad Sidenote- The American Cancer Society and the Breast Cancer Society want every woman to get MAMMOGRAPHY (X-rays) of their breasts and meanwhile everyone else (even them!) will tell you that radiation itself is one of the main causes of breast cancer!!!!!!!!!! Thermography is just as accurate and without the pain, without the radiation. ~~~~~~~~~~~~~~~~~~~~~~~ 3) COAXIAL TOMOGRAPHY- CT SCAN) Extremely detailed imagry because it uses a " slicing' technology so one can view a virtual scanning of the lumen of the GB. Hundreds of " cross-sections " , slices actually, are stacked like a deck of cards and the radiologist can examine them like fanning the deck. Still, this amazing technological miracle misses much, especially stones made of cholesterol and bile salts. Contrast media can also be introduced into the bile duct. A CT scan doses your body to the equivalent of 150+ chest X-rays as well! Therefore, avoid CT whenever possible! It's also colossally expensive. 4) MAGNETIC RESONANCE IMAGERY (MRI) The most sophisticated way to examine internal components without exploratory surgery. This is also a slicing imagery but in much greater detail and using super strong magnets and radio signals instead of radiation. The main hazard is if you have any iron-type metal in your body it turns it into a bullet! Otherwise, it probably won't be long before it's proven safe for pregnant women and infants. Oh, it's super loud, super claustrophobic and super-dooper expensive. So precise you can see the actual turbulence and vortices of the swirling liquid blood within the arteries! But, since bile is somewhat of a bog, MRIs still cannot provide a totally reliable diagnosis for GB conditions. All in all, modern medicine has come a long way, some of the new toys are very valuable and I'm glad they exist. But, I figure about 80% of ALL professionals are HACKS, or mediocre at best, and this includes Radiologists, Gastroenterologists and Surgeons (I came up with this figure because I know MY profession is at this level and we are all humans). The diagnostic tools are also vastly abused, WAY over-performed and still don't tell you, even in the best of hands, FOR SURE what you really need to know most of all! Bottom Line: You are still your own best doctor! Will in Minneapolis Quote Link to comment Share on other sites More sharing options...
