Filter by:The purpose of this clinical study is to compare the accuracy of linear endoscopic ultrasonography and magnified narrowband endoscopy in the diagnosis of invasive depth of early rectal cancer, and to provide more powerful evidence for the choice of surgical methods for early rectal cancer. Patients with early rectal cancer who will be examined by endoscopic ultrasonography or magnifying narrowband endoscopy in the department of gastroenterology and general surgery will be examined by linear endoscopic ultrasonography or magnifying narrowband endoscopy to examine the depth of invasion of early rectal cancer, and the results are compared with the postoperative pathological results of the patients as the gold standard. It provides strong evidence that the accuracy of linear endoscopic ultrasonography in judging the invasive depth of early colorectal cancer is not inferior to that of magnifying narrowband endoscopy.
Transanal endoscopic microsurgery is the main treatment option for rectal tumors such as large adenoma, early cancer because of lower complications and mortality rates and shorter hospital stays rather than conventional surgery. Particularly, However, transanal endoscopic microsurgerymust be performed under either general or spinal anesthesia, and expensive surgical instruments are required. Colorectal endoscopic submucosal dissection is a novel endoscopic procedure that enables en bloc resection of benign colorectal lesions and early colorectal cancer. Endoscopic submucosal dissectioncan be performed under conscious sedation without anesthesia, and there are fewer hospital days than those for transanal endoscopic microsurgery. In the present study, we compared the treatment efficacy and safety between endoscopic submucosal dissectionand transanal endoscopic microsurgery for the treatment of early rectal neoplasms and large rectal adenomas.
