In simple words: The doctor uses a thin, flexible tube with a camera to look inside your small intestine. They go past the first two sections but don't go all the way to the end. If they find any growths like polyps or tumors, they use a special tool like a tiny lasso to remove them.

This procedure involves the insertion of a flexible, fiberoptic endoscope through the mouth and into the small intestine, extending past the second part of the duodenum but not reaching the ileum.The purpose is to visualize and examine the lining of the small intestine. During the procedure, any identified tumors, polyps, or other lesions are removed using a snare technique. This involves passing a wire loop through the endoscope, encircling the growth, and then tightening the loop to remove it.

Example 1: A patient presents with obscure gastrointestinal bleeding.An enteroscopy is performed, and an angiodysplasia in the jejunum is identified and removed via snare technique., During a routine screening enteroscopy, a small polyp is discovered in the duodenum and removed with a snare., A patient with Peutz-Jeghers syndrome undergoes surveillance enteroscopy. Several small intestinal polyps are identified and removed by snare technique to prevent future complications.

Documentation should include the extent of the examination (how far the endoscope advanced), identification of any lesions (size, location, and number), method of removal (snare), and any complications. Photographs or video recordings of the procedure are also recommended.
