The most common complication of endoscopic polypectomy is hemorrhage.
In this study, researchers from Poland analyzed the risk factors of colonoscopic postpolypectomy bleeding in patients without bleeding disorders. They also examined the blood supply of resected polyps.
The study included 245 patients with 283 colorectal polyps measuring ≥1 cm in diameter.
All polypectomies were performed using the conventional endoscopic method.
The team recorded data on the patients' age and sex, as well as polyp location, size, shape, and pathology findings.
|Postpolypectomy hemorrhages occurred in 10%.|
Patients were observed for bleeding complications.
In addition, microscopic examination of the vascular supply of the removed polyps was performed.
The researchers found that postpolypectomy hemorrhages occurred in 10% of patients.
They determined that the bleeding rate correlated with the size, shape, and pathology results of resected polyps.
Microscopic analysis showed that sessile and thick-stalked pedunculated polyps are better supplied with blood vessels than other polyps.
Dr Sebastian Dobrowolski's team concluded, "Patients with polyps larger than 17 mm, pedunculated polyps with a stalk diameter >5 mm, sessile polyps, and malignant lesions of the colorectal region are at high risk of hemorrhage after endoscopic excision".
"Moreover, on the basis of microscopic study, broad-based polyps are supplied with a considerable number of blood vessels".
