Gastro-and colonoscopy (colonoscopy and gastrointestinal)
Gastroscopy-Gastroscopy
Stomach or colonoscopy help diagnose early malignant changes of the digestive organs. In a gastroscopy the esophagus, stomach, and is often also examines the duodenum. The doctor ordered, inter alia, with persistent dysphagia and upper abdominal discomfort or frequent heartburn an.de doctor puts in the investigation of a sheathed in plastic, just under an inch thick bundle of glass fibers and instrument hoses, mouth, pharynx, larynx, esophagus and stomach to prior to the duodenum. The glass fibers guide light in the dark and stomach

Images to the viewer who can see with an eyepiece or on a monitor. With the endoscope itself burns in the esophagus can detect ulcers of the stomach lining and duodenum as well as polyps and cancer foci. A small pair of pliers in the endoscope allows the painless removal of tissue samples for later examination. Small polyps and bleeding, the doctor with little

Instruments through the tube of the endoscope handle.
At least six hours before a gastroscopy you may eat any more. So you can swallow the plastic tube, the doctor sprays an anesthetic into your throat. If desired, you can also give a sedative.

Colonoscopy
In a colonoscopy, the doctor pushes the endoscope tube through the anus, the rectum in front of the colon and the last section of the small intestine. He can be inflammation,

Detect polyps or cancer foci and tissue samples taken. Polyps are, if possible, simultaneously with the endoscope and instruments removed for malicious components are examined.
The day before the reflection of the bowel is emptied by laxatives. This is a cleaning solution for several hours before the examination. Guide for a clear view, the physician must also some air into the intestine, which many patients feel uncomfortable.

Remedy tranquilizers or painkillers. Before a gastroscopy or colonoscopy should tell the doctor if you are taking blood-thinning drugs such as aspirin or warfarin, or heart disease is pregnant or already on the stomach or bowel surgery was.

Novel, gentle examination of the small intestine by a novel method: a mini-camera wanders through the digestive tract and transmits images to the outside twice a second, which are analyzed later by experts

So far, the doctors put the mirror effect of the stomach or intestine, a tube-like endoscope in the study region, with which they view the changes even more accurately and remove tissue samples. What is good for stomach, duodenum and colon, small intestine pushes the problems. Because of the lies approximately in the middle of the digestive tract through the mouth or anus, and is not achievable. Small intestine are therefore reflections previously associated with surgery, the surgeon opens the abdominal wall and intestines with a short section through which the doctors can then thread the endoscope. The capsule endoscopy in such cases is friendly, the principle is smart: In a capsule the size of a suppository insert a miniature digital camera, a small flash unit, a transmitter and a battery. On the stomach, the patient wears eight sensors that act as receivers. They are connected to a data recorder that is attached to the belt of the patient and records the images received.

The capsule is swallowed, it passes through – as usually the chyme – the digestive tract and shoot it twice per second, a photo that it sends to the sensors. The patient should behave as normal, and be allowed only a few hours before the investigation began after the capsule and eat anything because of the chyme would interfere with the recording. After the examination, the doctor inspects the recorded movie.

Difficulties arise when doctors find tumors or lesions on endoscopy, which they must operate. Since they made the traveling speed of the capsule and the time at which it has passed through the diseased small intestine point, can only conclude about where the damage is, the patient is currently in such a case a conventional intraoperative endoscopy is a must.
