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 …

Physical recovery after local resection of nonpedunculated rectal adenomas and T1 carcinomas: endoscopic submucosal dissection versus transanal minimally invasive surgery
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 …
Endoscopic resection of gastric subepithelial lesions: techniques and tips
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 …

Endoscopic Mucosal Incisional, Closure, ResectiON (E-MICRON): a novel technique for safe and efficient en bloc foregut resection
Post written by Talia F. Malik, MD, from Chicago Medical School at Rosalind Franklin University of Medicine and Science, North Chicago, Illinois, USA. In this study, we introduce a novel technique, “Endoscopic Mucosal Incisional, Closure, ResectiON (E-MICRON),” for safe and efficient en bloc resection of large gastric intramucosal lesions. Endoscopic submucosal dissection is recommended for en …
Endoscopic submucosal dissection to treat squamous cell carcinoma in situ of the anal canal
Post written by Michael Lajin, MD, from SHARP HealthCare, San Diego, California, USA. The standard treatment for squamous cell anal cancer is chemoradiation treatment. A few case reports from Japan address resecting early squamous cell anal cancer by endoscopic submucosal dissection (ESD). We presented a case series of squamous carcinoma in situ of the anal canal …
Impact of en bloc resection on long-term outcomes after EMR
Post written by Mayenaaz Sidhu, MBBS, from the Department of Gastroenterology and Hepatology, Westmead Hospital, and Westmead Clinical School, The University of Sydney, Sydney, New South Wales, Australia. The focus of this study was to assess long-term outcomes of sized-matched laterally spreading colorectal lesions (LSL) resected en bloc (e-EMR) as compared to piece-meal resection (p-EMR). …

Conscious transnasal hybrid ESD enables safe and painless en bloc resection
Post written by Yohei Minato, MD, from the NTT Medical Center, Tokyo, Japan. With the transnasal endoscopy, we successfully performed hybrid endoscopic submucosal dissection (ESD) of an early gastric cancer without sedation. Endoscopic Submucosal Dissection (ESD) is a technically demanding and time-consuming procedure, which is usually performed under sedation. Recently, hybrid ESD was developed as …

Technical difficulty in colorectal ESD
Kenichiro Imai, MD from the Division of Endoscopy, Shizuoka Cancer Center in Shizuoka, Japan discusses "Preoperative indicators of failure of en bloc resection or perforation in colorectal endoscopic submucosal dissection: implications for lesion stratification by technical difficulties during stepwise training." This study assessed predictors for failure of en bloc resection and perforation in colorectal endoscopic …
