How can colorectal neoplasms be treated during colonoscopy?

Area of Science:

• Gastroenterology
• Endoscopic Surgery
• Oncology

Background:

• Colonoscopy is a key tool for diagnosing and treating colonic diseases.
• Advancements in endoscopic technology have improved the diagnosis and management of colorectal neoplasms.
• Physicians widely regard colonoscopy as a primary study of interest for colonic diseases.

Purpose of the Study:

• To evaluate the efficacy and outcomes of endoscopic treatment for colorectal neoplastic lesions.
• To assess the safety and effectiveness of colonoscopic interventions for precancerous and cancerous growths in the colon.

Main Methods:

• A retrospective analysis of 11,447 colonoscopies and 5,502 endoscopic treatments for colorectal neoplasms (September 1999 - May 2003).
• Neoplasms were classified by macroscopic characteristics: protruded, sessile, lateral spreading, and depressed.
• Treatment modalities included snare polypectomy, hot forceps removal, and endoscopic mucosal resection.

Main Results:

• Histological analysis revealed 4,596 neoplastic lesions (4,376 adenomas, 220 adenocarcinomas) and 906 non-neoplastic lesions.
• 31 adenocarcinomas with submucosal invasion or positive margins required further surgery; 13 showed no residual tumor post-operation.
• Complications included 3 perforations and 96 bleedings; no procedure-related mortality or recurrent malignancy was observed during follow-up (14-56 months).

Conclusions:

• Endoscopic treatment for colorectal neoplasms is a simple and safe procedure.
• This approach can effectively lower the incidence and mortality associated with colorectal cancer.
• Colonoscopic interventions offer a viable option for managing neoplastic lesions in the colon.
