Per-oral endoscopic myotomy is safe and effective for pediatric patients with achalasia: A long-term follow-up study.

Background: Per-oral endoscopic myotomy (POEM) is emerging as a prefer treatment option for pediatric achalasia. However, data are limited on the long-term efficacy of POEM in children and adolescents with achalasia.

Aim: To evaluate the safety and long-term efficacy of POEM for pediatric patients with achalasia and compare those outcomes with adult patients.

Linked color imaging Lugol chromoendoscopy for esophageal squamous cell cancer and precancerous lesion screening: A noninferiority study.

Background: Lugol chromoendoscopy (LCE) has served as a standard screening technique in high-risk patients with esophageal cancer. Nevertheless, LCE is not suitable for general population screening given its side effects. Linked color imaging (LCI) is a novel image-enhanced endoscopic technique that can distinguish subtle diff-erences in mucosal color.

Prospective single-center feasible study of innovative autorelease bile duct supporter to delay adverse events after endoscopic papillectomy.

Background: Conventional endoscopic papillectomy (EP) is safe and effective for the treatment of small papilla adenoma to even large laterally spreading tumors of duodenum lesions. As reported by some existing studies, temporarily placing a prophylactic stent in the pancreatic and bile duct can lower the risk of this perioperative complication.

Aim: To evaluate the usefulness, convenience, safety, and short-term results of a novel autorelease bile duct supporter after EP procedure, especially the effectiveness in preventing EP.

Comparison between endoscopic submucosal tunnel dissection and endoscopic submucosal dissection for superficial neoplasia at esophagogastric junction: a case-matched controlled study of a single center from China.

Background: So far, little evidence is available for the comprehensive comparison of endoscopic submucosal tunnel dissection (ESTD) with endoscopic submucosal dissection (ESD) for the treatment of superficial neoplasia at esophagogastric junction (EGJ).

Methods: EGJ superficial neoplasia patients with ESTD treatment between January, 2021 and August, 2020 were retrospectively reviewed and individually matched at 1:1 ratio with those with ESD treatment according to lesion size, specimen area and lesion location, forming ESTD and ESD group, respectively. A sample size of 17 patients was collected for each group.

Clinical efficacy and prognostic risk factors of endoscopic radiofrequency ablation for gastric low-grade intraepithelial neoplasia.

Background: The use of radiofrequency ablation (RFA) has been reported in the treatment of gastric low-grade intraepithelial neoplasia (LGIN). However, its efficacy and prognostic risk factors have not been well analyzed.

Aim: To explore the efficacy and prognostic risk factors of RFA for gastric LGIN in a large, long-term follow-up clinical study.
