What is An LGI Endoscopy?
Lower GI endoscopy, famously known as a colonoscopy, allows your healthcare provider to view your lower gastrointestinal (GI) tract. Your entire colon and rectum can be examined. Or just the rectum and sigmoid colon can be examined. During a colonoscopy,examination of the large bowel and the distal part of the small bowel with a CCD camera or a fiber optic camera on a flexible tube passed through the anus.
Why One Needs To Get LGI Endoscopy Done?
LGI lets the doctor examine the dysfunctionalities of colon and the rectum.
What Is It Used To Treat?
Conditions that call for colonoscopies include gastrointestinal hemorrhage, unexplained changes in bowel habit, and suspicion of malignancy. Colonoscopies are often used to diagnose colon cancer but are also frequently used to diagnose inflammatory bowel disease.
When Doctor Suggests To Get This Treatment?
When done for other reasons, it is most often done to investigate the cause of blood in the stool, abdominal pain, diarrhea, a change in bowel habit, or an abnormality found on colonic X-rays or computerized axial tomography (CT) scan.
How To Prepare For the Procedure?
The colon must be free of solid matter for the test to be performed properly.For one to three days, the patient is required to follow a low fiber or clear-liquid only diet. Examples of clear fluids are apple juice, lemon-lime soda, lemonade, sports drink, and water. It is very important that the patient remain hydrated. Doctors have begun to utilize a technique used in colon hydrotherapy as an alternative to the standard preparation methods described above. In this case, special equipment is used to gently flush the patient’s colon with warm water, just prior to the colonoscopy procedure, in order to remove any bowel contents. This alleviates the patient from having to ingest large quantities of fluids, or risk nausea, vomiting, or anal irritation. The time required for preparation overall is significantly reduced, which often facilitates easier scheduling of the procedure.
What Will Happen During the Procedure?
During the procedure, the patient is often given sedation intravenously. The sedative is combined with intravenous pain medication to minimize any discomfort. The first step is usually a digital rectal examination, to examine the tone of the sphincter and to determine if preparation has been adequate. The endoscope is then passed through the anus up the rectum, the colon (sigmoid, descending, transverse and ascending colon, the cecum), and ultimately the terminal ileum. The endoscope has a movable tip and multiple channels for instrumentation, air, suction, and light. The colonoscope also contains a tiny video camera at its tip. The camera sends images to an external monitor so that the doctor can study the inside of your colon. The doctor can also insert instruments through the channel to take tissue samples (biopsies) or remove polyps or other areas of abnormal tissue. A colonoscopy typically takes about 30 to 60 minutes.
How One Will Feel After the Procedure?
After the procedure, some recovery time is usually allowed to let the sedative wear off. Outpatient recovery time can take an estimated 30–60 minutes. Most facilities require that patients have a person with them to help them home afterwards.
