Endoscopic mucosal resection and endoscopic submucosal dissection (ESD) are operative endoscopies that have been performed since a long time. Recently, an evolution of laparoscopy called transanal minimally invasive surgery began to be popularized, and it can be adopted in the face of difficult cases for endoscopic mucosal resection/ESD. In this video, a 36-year-old woman was submitted to transanal minimally invasive surgery resection, after unsuccessful ESD, for a 2-cm polyp located anteriorly in the anal canal, just beyond the pectineal line...

BACKGROUND AND AIMS: The colorectal endoscopic submucosal dissection (ESD) remains technically challenging, especially for older patients who frequently encounter complex chronic diseases and have a loose colon. However, only limited number of studies are available for the safety of ESD in older patients with especially large laterally spreading tumors. Therefore, in this retrospective study, we compared the outcomes of ESD for laterally spreading tumors (LST) ≥3cm(cm) in older patients to that in younger patients...

BACKGROUND: Although there have been several reports of treating large post-endoscopic submucosal dissection (ESD) ulcers by covering them with a polyglycolic acid sheet (PGAs), this approach presents problems regarding PGAs delivery. This study assessed the usefulness of a device delivery station system (DDSS) to evaluate the appropriate and rapid PGAs coating method with DDSS. METHODS: Thirty-nine of 41 patients who were diagnosed with early gastric cancer over 20 mm in diameter and pathologically diagnosed with well-differentiated adenocarcinoma were randomly allocated to the following two groups according to delivery method: the conventional PGAs delivery group (C group) (n = 19) and the new DDSS group (DDSS group) (n = 20)...

BACKGROUND AND STUDY AIM: Stricture is a major complication of esophageal endoscopic submucosal dissection (ESD) for superficial esophageal carcinoma. To date, various methods have been developed to prevent stricture. However, the mechanism by which different electrosurgical unit (ESU) modes affect the formation of post-ESD stricture has not been evaluated. This study aimed to compare the degree of stricture caused by two major ESU modes (ENDO CUT mode and FORCED COAG mode) in a porcine model...

A 47-year-old woman presented to our hospital with complaints of dysphagia. Esophagogastroduodenoscopy identified a submucosal tumor in the left wall of the esophagus that was diagnosed as a benign schwannoma on biopsy. Computed tomography revealed a tumor of length 60 mm in the thoracic esophagus, with its cranial edge at the level of the aortic arch. On endoscopy, a submucosal tunnel was created 40 mm proximal to the cranial edge of the tumor, and its oral end was dissected from the mucosal and muscular layers...

BACKGROUND AND OBJECTIVES: Endoscopic submucosal dissection (ESD) has become widely accepted method for treating early gastric cancer (EGC), but little is known about its role in patients with liver cirrhosis (LC). The aims of this study were to evaluate the outcomes of ESD in treating EGC in patients with LC. METHODS: The multicenter retrospective study identified 43 patients with chronic hepatitis B (CHB)-related cirrhosis undergoing ESD for treating EGC. The patients (LC group) were subdivided into two groups based on their Child-Pugh classification (CP-class): 32 with CP-class A (LC-A) and 11 with CP-class B (LC-B)...

BACKGROUND: To successfully resect early gastric cancer (EGC), prediction of lymph node metastasis is essential. Beyond endoscopic submucosal dissection (ESD) indication or lymphovascular invasion (LVI) are known risk factors associated with lymph node metastasis. However, accurate prediction of tumor invasion depth or LVI is impossible before endoscopic resection even when endoscopic ultrasound is used. The aim of this study was to identify the predictive factors associated with beyond ESD indication or LVI after ESD for EGC...

Several reports discussed colonoscopic surveillance after polypectomy and endoscopic mucosal resection (EMR) for colorectal polyps, but only a few reports focused on prognostic analyses, and none involved metachronous neoplasia after colorectal endoscopic submucosal dissection (ESD). We conducted the present study to assess the risk of adenoma recurrence requiring endoscopic treatment, and to establish appropriate post-ESD colonoscopic surveillance. We enrolled 116 patients who had undergone colorectal ESD at Okayama University Hospital between February 2008 and July 2014 and had been followed-up >12 months...

Michael B Wallace
In the United States, colorectal cancer (CRC) is the second-leading cause of cancer-related deaths. The most effective strategy for prevention of CRC is to screen for and remove precancerous polyps. There are various ways to screen for CRC. In the United States, the most common method is colonoscopy. Polyps are classified primarily through pathology. Size is the primary risk factor for malignancy. In general, the bigger the polyp, the greater the risk for malignancy. There are 3 basic options for removal: standard polypectomy; advanced resection techniques, known as endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD); and surgical removal...
