    Technique of sigmoidoscopy

    How is rectoscopy rectum? First, the proctologist examines the state of the guts finger method and anoscope. The doctor then explains to the particular situation, which should take the patient, proper breathing, warns of possible unpleasant moments and sensations.

    The correct approach procedure videomicroscopy not leads to pain.

    Rectoscopy (sigmoidoscopy) is as follows:

    • the patient strips to the waist and laid on its side or take the knee-elbow position;
    • the device is treated with a special tool that facilitates the promotion, and injected a few inches into the rectum;
    • a little serves the air to the folds of the mucous membrane disposed;
    • insert the eyepiece and examine the condition of the walls, gradually pushing the proctoscope down the intestine;
    • during inspection it is possible to cleanse the colon the pumps, removal of small polyps (coagulation loop), and the collection of material for histology;
    • carefully remove the instrument from the intestines.

    Duration rectoscopy is 5-10 minutes, depending on what actions will produce the doctor in the inspection process.

    Do I need anesthesia with sigmoidoscopy?

    In many cases, rectoscopy is performed without anesthesia and is well tolerated by patients. Sometimes, on individual request, can be used local anesthesia or intravenously (if patient insists on it). Mandatory anesthesia carried out in the presence of damage to the wall of the colon or back passage, at available cracked, need for surgical intervention.

    The use of rectoscopy in children

    Unlike rectoscopy colonoscopy from

    What is the difference between rectoscopy and colonoscopy? The main difference is in the area of surface surveyed and intestine. The depth of insertion of the proctoscope is up to 60 cm, and can only examined the distal part of the colon, the colonoscope is designed to study the entire colon and enter 1.5 m.

    In addition, colonoscopy is more painful, it is required to use anesthesia. Sigmoidoscopy can undergo without anesthesia.

    Another difference between these diagnostic methods is the duration. Holding sigmoidoscopy takes 5-15 minutes, while colonoscopy lasts about an hour.

    The preparatory phase to the conduct of colonoscopy requires more time. Diet should begin 5 days prior to the survey. If assigned rectoscopy, it is enough 2-3 days.

    Also colonoscopy rectoscopy different from those that have a higher risk of complications.

    If we consider that it is better – colonoscopy or videoendoscopy – from the patient, the choice will be in favor of the second method. But to oppose research does not make sense, as each of them is designed for a particular situation. The doctor may need to see a full picture of the state of the colon. And this will need to do a colonoscopy.
