İnverte rektal divertikül: Nadir bir kolonoskopik bulgu

Kolonda inverted divertikül kolonoskopide nadir görülebilen bir bulgudur. Rektumda inverted divertikül görülmesi ise çok daha nadirdir. Kolonda inverted divertiküller, kolon poliplerine benzerler. Tüm polypoid lezyonlarda dışlanmalıdırlar. Poliplerden ayırt edilmesi, polipektomi yapılması durumunda kolon perforasyonu olma riski nedeniyle çok önemlidir. İnverted rektal divertiküller kolonoskopi sırasında çok nadiren görülürler. Burada rektumda inverted divertikül saptanan nadir görülen bir vakayı sunacağız.

Inverted rectal diverticulum: A rare colonoscopic finding

Inverted diverticulum in colon is very rare finding on colonoscopy. The appearance of reverse diverticulum in the rectum is much rarer. Inverted diverticulums in the colon are similar to colon polyps. They should be excluded in all polypoid lesions. Differentiation from polyps is very important because of the risk of colonic perforation in case of polypectomy. Inverted rectal diverticulums are very rarely seen during colonoscopy. Here, we will present a rare case of inverted diverticulum in the rectum.
