Diverticulosis and Diverticulitis

3mm Polyp Sigmoid Colon

Colonic diverticula are fingerlike outpouchings protruding outward from the intestinal lumen. True and pseudodiverticula. A distinction is made between true diverticula and pseudodiverticula. The seldom-occurring true diverticula are present at birth and usually only appear in the right hemicolon. Pseudodiverticula, which occur much more frequently, are acquired. They can be found anywhere in the colon, though they tend to appear in the left hemicolon. True diverticula are characterized by...

Polyps and Polyposis Syndromes

Colonoscopy Polyps

The term polyp describes a mass of tissue protruding into the lumen of the bowel, without implying pathological relevance. Polyps can be stalked, round, or sessile and can vary in size. They can occur as solitary or multiple polyps. Polypoid lesions are the most common pathological finding of colonoscopy. Polyps can only be classified by histological evaluation. Pathologically and anatomically, polyps of epithelial tissue are distinguished from those of mesodermal tissue and there are also a...

Passing the Anal Sphincter

Perianal Skin Tags Form

After completing inspection and palpation and, if necessary, administering an analgesic, the actual endoscopic examination can begin. A local anaesthetic lubricating jelly, such as a lubricant containing Lidocain, should be applied liberally. The endoscope tip is then inserted in the rectum and guided digitally without visualization. The examiner should explain to the patient the steps being taken and inform the patient that he may experience the urge to evacuate his bowels. The endoscope tip...

Looping and Using External Compression Techniques

Sigmoid Straighten Colonoscopy

Using external compression or splinting techniques can often make the examination much easier for both the patient and examiner and in some cases, it may be the only means of completing ileocolonoscopy. Proper use of compression technique requires close cooperation between the examiner and assistant compression should be performed with targeted, steady pressure without using force. The localization of optimal pressure points is for the most part based on the experience of the examiner and...
