Yüksek Derece Displazili Dev Tubüler Adenom

Öz

Malignite riski yüksek olan rektal adenomlar sıklıkla anal kanama ve mukus akıntısıyla görülür. Displazi alanları içeren 2 cm'den büyük poliplerde malignite riski %50'den fazladır ve displazi olasılığı villöz komponent oranının fazlalığı, polipin anal bölgeye yakınlığı ve polip boyutunun artışı ile displazi olasılığı korele seyreder. Büyük, lümeni çevreleyen poliplerin endoskopik veya transanal girişimle tedavisi zordur ve cerrahi müdahale gerektirir. Bu yazıda; rektal mukus akıntısı ile başvuran tetkiklerinde yüksek dereceli displazili ve villöz komponent içermeyen tübüler adenomu olan kadın hastamızı, alt anterior rezeksiyon ve koloanal anastomoz yaparak tedavi ettiğimiz olguyu sunuyoruz.

High-grade dysplasia in giant tubular adenoma

Öz

Rectal adenomas with a high risk of cancer frequently occur in anal bleeding and mucus discharge. The risk of malignancy is greater than 50% in polyps larger than 2 cm and includes areas of dysplasia, and the likelihood of dysplasia is correlated with the excess of the villous component ratio, the proximity of the polyp to the anal region, and the increase in size. Large, lumen-encircling polyps are difficult to treat with endoscopic or transanal intervention and necessitate surgical intervention. In this article, we present a female patient who had rectal mucus discharge and had a lower anterior resection and coloanal anastomosis after developing a tubular adenoma with high-grade dysplasia and no villous component.
