Abstract

Background/aims: The purpose of this study was to research the efficacy and reliability of endoscopic rectal ultrasonography in local staging (T and N stages) of rectal tumors. Materials and Methods: This retrospective study was carried out by the Department of Gastroenterology, İzmir Atatürk Training and Research Hospital, which is tertiary level. Thirty-one patients with adenocarcinoma were included in the study. The patients found operable according to computed tomography underwent preoperative local staging by endoscopic ultrasonography. Radial endoscopic ultrasonography and T and N stages were evaluated. Results: It was observed that endoscopic rectal ultrasonography had 80.6% accuracy, 93.4% sensitivity, and 96.5% specificity in T stage; 70% accuracy, 70% sensitivity, and 86% specificity in the detection of presence of lymph node; and 76% accuracy, 100% sensitivity, and 22% specificity in the detection of the nature of lymph node. Conclusions: In this study, it was observed that endoscopic rectal ultrasonography is an efficient and reliable method in the detection of local lymph node and the depth of invasion of rectal tumors (T staging), although it is not reliable enough to determine the characteristics of lymph nodes.

Özet

Amaç: Çalışmanın amacı, endoskopik rektal ultrasonografinin, rektal tümörlerin lokal evrelemesinde (T ve N evrelemesi) etkinli- ğini ve güvenilirliğini araştırmaktır. Gereç ve Yöntem: Bu retrospektif çalışma, tersiyer düzeydeki İzmir Atatürk Eğitim ve Araştı rma Hastanesi, Gastroenteroloji bölümünde yürütüldü. Adenokarsinom tanılı 31 hasta çalışmaya dahil edildi. Bilgisayarlı tomografiye göre ameliyat edilebilir durumdaki hastalara, endoskopik ultrasonografi ile ameliyat öncesi lokal evreleme yapıldı. Radial endoskopik ultrasonografi ve T ve N evreleri değerlendirildi. Bulgular: endoskopik rektal ultrasonografinin T evrede %80,6 doğruluk, %93,4 sensitivite, %96,5 spesifite, ve lenf nodu varlığı tanımlamasında %70 doğruluk, %70 sensitivite, %86 spesifite, ve lenf nodlarının niteliğini tanımlamada %76 doğruluk, %100 sensitivite, %22 spesifite olduğu izlendi. Sonuç: Bu çalışmada, endoskopik rektal ultrasonografinin lenf nodu özelliklerini tanımlamada yeterli olmamasına rağmen, lokal lenf nodunu, rektal tümörün (T evreleme) invazyon derinliğini tanımlamada etkili ve güvenilir bir metod olduğu gözlendi.
