Official Description

Colonoscopy, flexible; with removal of tumor(s), polyp(s), or other lesion(s) by snare technique

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

A flexible colonoscopy is a diagnostic and therapeutic procedure that involves the insertion of a colonoscope into the rectum and advancement through the entire colon to the cecum or the terminal ileum. This procedure allows for direct visualization of the mucosal surfaces of the colon, enabling the identification and assessment of abnormalities such as tumors, polyps, or other lesions. During the colonoscopy, air insufflation is utilized to expand the colon, which helps in separating the mucosal folds for improved visibility. When a lesion is detected, the procedure can proceed to the removal of the lesion using a snare technique. This technique involves placing a wire snare loop around the lesion, which is then heated to excise and cauterize the tissue simultaneously. The snare technique is particularly effective for removing larger lesions and can be performed either en bloc, where the entire lesion is removed in one piece, or piecemeal, where the lesion is removed in sections. Following the removal, the endoscope is withdrawn, and the mucosal surfaces are re-examined for any signs of complications such as ulcerations or bleeding.

1. Indications

The flexible colonoscopy with removal of tumor(s), polyp(s), or other lesion(s) by snare technique is indicated for various conditions and symptoms, including:

  • Detection of Colorectal Cancer This procedure is often performed as a screening tool to identify early signs of colorectal cancer in patients at risk.
  • Removal of Polyps Polyps are abnormal growths in the colon that may be precursors to cancer; their removal is crucial for cancer prevention.
  • Management of Lesions Lesions that may cause symptoms such as bleeding or obstruction can be effectively managed through this procedure.
  • Evaluation of Gastrointestinal Symptoms Patients presenting with unexplained gastrointestinal symptoms, such as rectal bleeding, changes in bowel habits, or abdominal pain, may require this procedure for diagnosis and treatment.

2. Procedure

The procedure involves several key steps to ensure effective removal of the identified lesions:

  • Step 1: Preparation The patient is prepared for the procedure, which may include dietary restrictions and bowel cleansing to ensure the colon is clear for optimal visualization.
  • Step 2: Insertion of the Colonoscope The flexible colonoscope is inserted into the rectum and carefully advanced through the colon. Air insufflation is utilized to expand the colon, allowing for better visualization of the mucosal surfaces.
  • Step 3: Inspection of the Colon The physician inspects the colon for any abnormalities, including tumors, polyps, or lesions. Any identified lesions are documented for further action.
  • Step 4: Snare Technique Application A wire snare loop is placed around the lesion. The snare is heated to excise the lesion while simultaneously cauterizing the tissue to minimize bleeding.
  • Step 5: Removal of Lesions Lesions may be removed in one piece (en bloc) or in sections (piecemeal), depending on the size and nature of the lesion. Multiple applications of the snare may be required for larger lesions.
  • Step 6: Post-Removal Inspection After the lesion is removed, the endoscope is withdrawn, and the mucosal surfaces are re-inspected for any signs of complications such as ulcerations or bleeding.

3. Post-Procedure

Post-procedure care involves monitoring the patient for any immediate complications, such as bleeding or perforation. Patients may experience mild discomfort or cramping following the procedure, which typically resolves quickly. Instructions regarding diet and activity levels are provided, and follow-up appointments may be scheduled to discuss pathology results from any biopsies taken during the procedure. It is essential for patients to report any unusual symptoms, such as severe abdominal pain or significant bleeding, to their healthcare provider promptly.
