Endoscopic submucosal dissection of a large cecal tumor extending into the appendiceal orifice in a patient with intact appendix
Endoscopic resection of cecal tumors extending into the appendiceal orifice in patients with intact appendix is known to be technically difficult, associated with higher risk of perforation and appendicitis. Consequently, surgical resection has been the conventional treatment even for adenomas.1,2 Recently, there have been some reports of endoscopic resection for similar tumors as a result of improved devices and accumulated experience with these complex resections. However, reported experience on the safety and effectiveness of endoscopic resection is lacking, and the best management for these lesions is still variable depending on the availability of expertise.Double-tunneling butterfly method for endoscopic submucosal dissection of extensive rectal neoplasms
Endoscopic submucosal dissection (ESD) is the preferred technique for en bloc resection of superficial colorectal neoplasms. Resection of extensive lesions with ESD can be challenging, owing to loss of orientation in the submucosal space. In this case series, we describe the double-tunneling (DoT) butterfly method for ESD of extensive rectal neoplasms.
