Summary: Endoscopic submucosal dissection (ESD) is the preferred treatment for early gastric cancer (EGC) with low risk of lymph node metastasis. Predicting the risk of local recurrence after ESD is crucial for management and prevention. Factors associated with a higher risk of local recurrence include lesion size >= 15 mm, incomplete histologic resection, undifferentiated adenocarcinoma, scar, and the absence of erythema of the surface. Regular endoscopic surveillance is important to predict local recurrence, especially in patients with larger lesions, incomplete histologic resection, surface changes of scars, and no surface erythema.

Summary: This study aimed to elucidate the endoscopic causes and characteristics of missed gastric cancers (MGCs) after endoscopic submucosal dissection (ESD) for early gastric cancer (EGC). The results showed that the endoscopic causes of MGCs included perceptual errors, exposure errors, sampling errors, and inadequate preparation. Logistic regression analysis revealed the risk factors for perceptual errors and the sites of exposure errors.

Summary: This study proposed a risk factor-based statistical model for optimal surveillance intervals for gastric adenoma after ESD, identifying factors such as male gender, protruded scar, and age as predictors of recurrence. Customized surveillance intervals were developed based on these risk factors, with high-risk patients recommended more frequent monitoring.

Summary: This study aimed to evaluate the feasibility and safety of endoscopic submucosal dissection (ESD) in early esophageal cancer after chemoradiotherapy (CRT) by analyzing the association between submucosal fibrosis and ESD. The results showed that although ESD can be reliably performed without adverse events in early esophageal cancer, it is more difficult for lesions with strong submucosal fibrosis, leading to longer procedure time.

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.

Summary: This study aimed to clarify the risk factors for lymph node metastasis (LNM) after non-curative endoscopic submucosal dissection (ESD) for early gastric cancer (EGC), and evaluate the reliability of the eCura system in LNM risk stratification. Results showed that upper third location and deep submucosal invasion were independent risk factors for LNM and local cancer residue. Additionally, the eCura system was significantly associated with LNM and cancer recurrence.

Summary: This study retrospectively analyzed the preoperative endoscopic evaluation in endoscopic submucosal dissection (ESD) for early gastric cancer and precancerous lesions. Accurate preoperative assessment of lesion type, extent, and depth of invasion is helpful in improving the complete resection rate and reducing the risk of additional surgery in ESD.

Summary: This study analyzed the characteristics, risk factors, treatment, and follow-up outcomes of patients with metachronous gastric neoplasms (MGN) following curative endoscopic submucosal dissection (ESD). It found that initial multiplicity was the sole independent risk factor of MGN, and patients with MGN had significantly lower disease-specific survival rate compared to those without MGN. Regular and long-term surveillance endoscopy may be beneficial for patients with initial multiple neoplasms.

Summary: After colorectal endoscopic submucosal dissection (ESD), piecemeal resection and histological incomplete resection were identified as risk factors for local recurrence. Short-term surveillance endoscopy is recommended, especially for patients with early cancers.

Summary: This document from the American Society for Gastrointestinal Endoscopy (ASGE) provides a detailed description of the methodology used to evaluate the role of endoscopic submucosal dissection (ESD) in the management of early esophageal and gastric cancers. The guideline suggests that ESD is preferred over EMR and/or surgery in certain patient populations, based on tumor characteristics. Different recommendations are provided for different types of cancer and lesions, taking into consideration tumor size.

Summary: This study aimed to evaluate the impact of P. gingivalis on local recurrence after ESD treatment of early ESCC or HGD. The amount of P. gingivalis was assessed in 205 patients. The study found that overabundance of P. gingivalis was associated with invasion depth, post-ESD stricture, and local recurrence. A nomogram integrating P. gingivalis, lymphovascular involvement, and lesion length performed well for prediction of post-ESD local recurrence.

Summary: A 93-year-old female underwent curative endoscopic submucosal dissection for intramucosal gastric cancer, which resulted in a longitudinal laceration at the esophagogastric junction. A new lesion was found 6 months later, requiring a second resection with similar features to the original lesion, indicating recurrence due to implantation of tumor cells in the mucosal laceration. Endoscopists should be aware of the risk of implantation after gastric ESD.

Summary: This study examined the knowledge, attitude, and practice of early gastric cancer (EGC) survivors following endoscopic submucosal dissection (ESD) regarding gastric cancer recurrence. The results showed inadequate knowledge, positive attitude, and poor practices among EGC survivors in monitoring recurrences after ESD. Adequate knowledge, positive attitude, and a longer time since the last ESD were associated with better practice.

Summary: This study evaluated the severity of intraoperative bleeding and analyzed the risk factors of postoperative bleeding associated with endoscopic submucosal dissection (ESD) for gastric neoplastic lesions. It found that proximal location of lesions was a significant risk factor of major intraoperative bleeding, while chronic kidney disease and intraoperative bleeding were independent risk factors of postoperative bleeding.

Summary: In early gastric cancer (EGC) patients without lymphatic invasion (LI), tumor size larger than 3 cm, submucosal invasion, and undifferentiated histologic type were significant risk factors for lymph node metastasis (LNM). The expanded criteria for endoscopic resection (ER) may be tolerable in cases without LI, even though there is a minimal risk of LNM.

Summary: The simplified magnifying endoscopic classification developed by the Japan Esophageal Society is useful for estimating the invasion depth of superficial esophageal squamous cell carcinoma (SESCC). The diagnostic accuracy for type B2 vessels was low, but may be improved by using B2 >= 7 mm and B2i.

Summary: Sporadic non-ampullary duodenal adenoma (SNADA) is a rare disease with clinical characteristics and treatment strategies that are not yet fully understood. Research suggests that for older adults, patients with poor prognosis, or small lesions, initially opting not to perform resection could be a viable strategy due to low cancer development rates and absence of disease-specific mortality.
