Post written by Robert Bechara, MD, from Queen's University, Kingston Health Sciences Center, Kingston, Ontario, Canada. This video demonstrates the use of a thulium laser system for colorectal endoscopic submucosal dissection (ESD) in a 68-year-old man with a 3.5-cm rectal lesion detected following a positive fecal immunochemical test result. The lesion was classified as Paris Is and …

Post written by Satoki Shichijo, MD, PhD, from Osaka International Cancer Institute, Osaka, Japan. Endoscopic submucosal dissection (ESD) was performed for 1763 patients with 1845 lesions (right-sided colon, 1018; left-sided colon, 827) between February 2011 and April 2023. Thirty-two delayed perforations (26 between 2011 and 2020; 6 between 2021 and 2023) occurred. Muscle injury occurred during ESD …
Post written by Naoya Tada, MD, PhD, Akira Dobashi, MD, PhD, and Kazuki Sumiyama, MD, PhD, from the Department of Endoscopy, The Jikei University School of Medicine, Tokyo, Japan. Our video demonstrates a combined technique of scar incision and endoscopic balloon dilation (EBD) for severe benign esophageal strictures following endoscopic submucosal dissection or esophagectomy. After identifying areas of severe fibrosis, we selectively …
Post written by Daan A. Verhoeven, BSc, and Hao Dang, MD, PhD, from Leiden University Medical Center, Leiden, The Netherlands. In this meta‑analysis, we set out to evaluate how often local recurrence occurs following en bloc endoscopic submucosal dissection (ESD) of colorectal neoplasia when the horizontal margin is positive or indeterminate. We compared that risk to cases with a negative horizontal margin …

Post written by Nik Dekkers, MD, from Leiden University Medical Center, Leiden, The Netherlands. The focus of our study was to quantitatively assess physical recovery after endoscopic submucosal dissection (ESD) and transanal minimally invasive surgery (TAMIS) for large rectal lesions. We used wearable accelerometers (smartwatches) to objectively measure physical activity and to investigate key factors influencing recovery. We …
Post written by Kais Zakharia, MD, from the Division of Gastroenterology, University of Massachusetts Chan Medical School–Baystate Medical Center, Springfield, Massachusetts, USA. Barrett’s esophagus (BE) remains the only known precursor to esophageal adenocarcinoma and, although the risk of progression varies with segment length and degree of dysplasia, endoscopic management has increasingly replaced surgery in well-selected patients. In …
Post written by Michael Lajin, MD, from Sharp HealthCare, San Diego, California, and Fateh Bazerbachi, MD, from CentraCare, St. Cloud, Minnesota, USA. This article presents the different endoscopic modalities for resecting gastric subepithelial lesions (SELs) including: Submucosal tunneling endoscopic resection Full-thickness resection using the gastric full-thickness resection device Endoscopic submucosal dissection Exposed endoscopic full-thickness resection Laparoscopic endoscopic cooperative surgery …

Post written by Hiroki Hayashi, MD, from the Division of Gastroenterology, Department of Medicine, Jichi Medical University, Shimotsuke, Japan. EMR and endoscopic submucosal dissection are widely used for treating intramucosal gastric neoplasms. However, securing a clear visual field in a stomach with residue is challenging. In this article, we present 2 cases in which tumors …
