Summary
Colonic malignancies may spontaneously regress or slough, making them undetectable after initial diagnosis. This phenomenon highlights the need for precise lesion localization techniques during endoscopy for colon cancer management.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Colorectal Surgery
Background:
- Colonoscopy with biopsy is standard for diagnosing colonic malignancies.
- Endoscopic localization of lesions can be challenging due to imprecise distance measurements from the anal verge.
- Preoperative barium enema or intraoperative colonoscopy are sometimes used to pinpoint difficult-to-locate lesions.
