We found that despite experienced endoscopists performing colonoscopy it was difficult to predict which polyps are malignant. However large pedunculated polyps seem to carry a significant malignant potential.doi:10.1136/gut.2009.209015rFellows, H
Colonoscopy is the investigation of choice for the patient with chronic intestinal blood loss (Farrands, 1986; Danesh et al, 1987; Berry et al, 1988; Steger and Spencer, 1988). The diagnostic yield during elective investigation of obscure blood loss, even when a barium enema examination is ...
Lynch syndrome: Lynch syndrome is a dominantly inherited cancer predisposition due to a germline mutation in a DNA mismatch repair gene. The adenoma-cancer sequence is accelerated, and adenomas are typically right sided and of low profile. Even yearly colonoscopy may not protect against interval canc...
I had a colonoscopy at Kaiser Permanente in July 2007 and they found a very large 5 cm flat sessile villous adenoma colon polyp in my cecum (at the start of the colon near the junction with the small intestine). They could not remove it during the colonoscopy because it was so large an...
This is a multicenter randomized clinical trial in patients with a non-pedunculated polyp larger than 20 mm in the rectum, sigmoid, or descending colon suspected to be an adenoma by means of endoscopic assessment. Primary endpoint is recurrence rate at follow-up colonoscopy at 6 months. Secondary...
This resulted in a missed polyp rate of 38.6%, a 'missed cancer rate' at one year of 6/150 patients (4%) and an overall 'missed cancer rate' of 0.12% or 1 in 827 colonoscopies. 2 cancers were found in patients who had a repeat colonoscopy after 2 years, both in the ascending ...
Synchronous polyps were detected in 67.2 % of patients undergoing complete colonoscopy during EMR. Presence of HGD/adenocarcinoma in the large polyp, localization of any synchronous polyp in the rectosigmoid colon and occurrence of multiple synchronous polyps were associated with presence of HGD/...
Colonoscopy was performed to the cecum or terminal ileum with white light colonoscopic examination. Polyps suspicious of invasive cancer (the presence of ulceration, induration, friable mucosa, or non-lifting sign[11]) were referred for surgical resection. Polyp size (measured in comparison with ...
Synchronous polyps were detected in 67.2 % of patients undergoing complete colonoscopy during EMR. Presence of HGD/adenocarcinoma in the large polyp, localization of any synchronous polyp in the rectosigmoid colon and occurrence of multiple synchronous polyps were associated with presence of HGD/...
In recent years, due to an increase in the number of patients who suffer from a polyp or tumor in the large intestine, the number of examinations or operations for them has been growing accordingly. The examination of the large intestine is carried out by CT examination, endoscopy or X-ray...
