Summary: This study investigated the utility and short-term outcomes of different endoscopic resection techniques for relatively small superficial non-ampullary duodenal adenomas (SNADAs). The results showed that there was no significant difference in recurrence risk among the different techniques, and underwater endoscopic resection appeared to be a simple and safe option for these lesions.

Summary: A retrospective study found that the use of a water pressure method significantly reduced intraprocedural perforation rate during duodenal endoscopic submucosal dissection, while both the water pressure method and DualKnife J significantly shortened procedure times.

Summary: This study evaluated the efficacy and safety of endoscopic submucosal dissection (ESD) for duodenal subepithelial lesions (SELs). The results showed that ESD is relatively safe and feasible for duodenal SELs, especially for lesions no more than 2 cm in size.

Summary: Endoscopic submucosal dissection (ESD) is feasible and effective for the management of small duodenal neuroendocrine tumors (DNETs), but caution is advised due to a high risk of adverse events such as perforations and major bleeding, as well as the possibility of pathologically incomplete resections.

Summary: This study aimed to elucidate the learning curve for duodenal endoscopic submucosal dissection (ESD). The cumulative sum curve analysis revealed four distinct phases: the learning phase, proficiency phase, mastery phase, and phase after the introduction of general anesthesia. The study found that duodenal ESD requires 25 cases to gain proficiency and 50 cases to achieve mastery even for an endoscopist with extensive non-duodenal ESD experience.

Summary: Early endoscopic diagnosis and optimal treatment selection for SNADETs may improve the poor prognosis of duodenal cancer. Different endoscopic imaging techniques and resection methods can be used for diagnosis and treatment of SNADETs.

Summary: Compared with ESD, ESD-ME achieved a higher histological complete resection rate, had a similar rate of complications, and required a similar procedure time for rectal NETs < 16 mm in diameter without metastasis.

Summary: This study examined the outcomes of salvage hybrid ESD (SH-ESD) and identified its indications for cases with remaining undissected submucosa less than 20mm in diameter. SH-ESD can be an alternative surgical method with shorter procedure time and comparable en bloc resection rate.

Summary: This study aimed to analyze the incidence of post-ESD strictures after wide-field duodenal ESD. The results showed that suturing may prevent post-ESD stricture formation in cases of duodenal tumors with mucosal defects occupying a large circumference.

Summary: The German ESD registry study evaluated the outcomes of ESD in early malignant lesions and found high en bloc resection rates but modest curative resection rates in Germany. High-volume centers had better outcomes compared to middle or low-volume centers, with factors like age, tumor size, and treatment location affecting non-curative ESD outcomes.

Summary: This document is part of a series prepared by the American Society for Gastrointestinal Endoscopy Training Committee. It contains recommendations for an endoscopy training curriculum, particularly for ESD training. The document provides an overview of favored techniques for ESD performance and training, as well as guidance on available resources for trainers, with anticipated future modifications and updates.

Summary: This study assessed the effectiveness of the underwater clip closure method for complete closure of duodenal mucosal defects. The results showed a success rate of 100%, indicating that this method is a feasible option regardless of the size or location of the defects.

Summary: Comparing the safety and efficacy of CSP and HSP for the removal of nonampullary duodenal adenomas, CSP is equally effective and potentially safer with fewer delayed adverse events compared to HSP.

Summary: This study suggests that patients with early gastric cancer who meet the surgical indications can be treated with endoscopic submucosal dissection. The location of the tumor, as well as its size and histological features, are key factors in determining whether curative resection can be achieved with ESD.
