Adenoma - pedunculated 1 (small, tubular)
This small pedunculated polyp of the sigmoid colon was discovered in the context of a preventive colonoscopy and removed at the same session. The 60-year-old white female patient denied any symptoms. Histological examination revealed a tubular adenoma with a short pedicle, with no evidence of dysplasia. Secure margins were achieved.
The videoclip shows the small, pedunculated polyp. Excision did not require submucosal injection. During excision, a small white cautery mark developed due to contact between the head of the polyp and the bowel wall.
Polyps of this size can be removed without submucosal injection. The small cautery mark on the bowel wall has no clinical relevance; such injuries can be avoided by holding the polyp in the intestinal lumen during the excision procedure.
