“…EUS has been considered useful for tumor staging of colorectal cancers; however, its real clinical impact for deciding on the indication for surgical operation is still not clear [13][14][15]. In the present EUS study, when the change for the third layer (submucosal layer) was 1 millimeter or more the histological SM invasion depth was 4.3 mm.…”

Purpose: To retrospectively analyze the results of our therapeutic recommendations for EMR and surgical operation using thin-probe EUS for patients with early colorectal neoplasms. Methods:We retrospectively analyzed the therapeutic recommendation for using EUS and the results in 63 lesions of 63 patients. When the depth of the change for the third layer (submucosal layer) was 1 millimeter or more, we recommended surgical operation(EUS operation-recommended group). Results: Surgical operation was suitable for all of lesions in the EUS-operation-recommended group (23 lesions of 23 patients). Conclusion:We think that a change of 1 millimeter or more in the third layer (corresponding to the submucosal layer) in EUS for colorectal neoplasms may be a useful finding for surgical decision making.

“…Matsumoto et al also demonstrated the diagnostic superiority of EUS (probe-EUS) in their study (negative predictive value for deep invasion of 91% vs. 54%, respectively) [19]. In contrast, Fu et al reported that there was no significant difference between magnifying chromoendoscopy and EUS for the preoperative staging of early colorectal cancer [20].…”

The introduction of colorectal endoscopic submucosal dissection (ESD) has expanded the applications for endoscopic treatment; as a result, lesions with low metastatic potential can be treated endoscopically regardless of the lesion size. The most attractive feature of ESD is the achievement of en bloc resection with a lower local recurrence rate in comparison to that of endoscopic piecemeal mucosal resection. However, in case of gastric cancers, ESD is not as widely applied to the treatment of colorectal neoplasms because of its technical difficulty, longer procedural time, and increased perforation risk. In the movement toward diversified endoscopic treatment strategies for superficial colorectal neoplasms, endoscopists who begin to perform ESD need to recognize the indications of ESD, as well as the technical issues and associated complications of this procedure.

“…A previous study showed that endoscopic ultrasonography had higher diagnostic accuracy than pit patterns based on magnifying endoscopy in T staging [18], whereas another study found that the diagnostic accuracy of those methods was similar [19]. Recently, Mukae et al [20] found that the sensitivity and specificity of endoscopic ultrasonography in estimating the deep invasion depth of early CRC was 90 and 87%, respectively.…”

Background: Colorectal cancer (CRC) is the third most commonly diagnosed cancer in males and the second in females, with an estimated 1.4 million cases and 693,900 deaths in 2012. Colonoscopy is the cornerstone for the detection and prevention of CRC. In addition, endoscopic treatment for CRC at an early stage can effectively improve patients' quality of life and cure rate. Summary: This review focuses on endoscopic approaches, including white light endoscopy, chromoendoscopy, magnifying endoscopy and therapeutic endoscopy, for the evaluation and treatment of superficial colorectal neoplasms. Key Message: Understanding the preoperative evaluation, indications and techniques of endoscopic mucosal resection/endoscopic submucosal dissection as well as postoperative surveillance for superficial colorectal neoplasms is critical for providing appropriate management to the patients. Practical Implications: Endoscopic therapy, a method preserving organ function and improving quality of life, is a widely applied microinvasive treatment for superficial colorectal neoplasms. This review describes the basics and developments of endoscopic approaches and may facilitate daily practice for superficial colorectal neoplasms.

Staging of Early Colorectal Cancers: Magnifying Colonoscopy versus Endoscopic Ultrasonography for Estimation of Depth of Invasion

Abstract: Although, there is a substantial difference in the overall diagnostic accuracies, it is not statistically significant. Therefore, we conclude that magnifying colonoscopy is at least as accurate as EUS for preoperative staging of early CRCs.
