The role of type II esophageal microbiota in achalasia: Activation of macrophages and degeneration of myenteric neurons.

Objective: The gut microbiota plays a critical role in the appropriate development and maintenance of the enteric nervous system (ENS). Esophageal achalasia (EA) is a rare motility disorder characterized by the selective degeneration of inhibitory neurons in the esophageal myenteric plexus. This study aimed to evaluate the composition of the esophageal microbiota in achalasia and explore the potential microbial mechanisms involved in its pathogenesis.

A single-cell transcriptional landscape of immune cells shows disease-specific changes of T cell and macrophage populations in human achalasia.

Achalasia is a rare motility disorder of the esophagus caused by the gradual degeneration of myenteric neurons. Immune-mediated ganglionitis has been proposed to underlie the loss of myenteric neurons. Here, we measure the immune cell transcriptional profile of paired lower esophageal sphincter (LES) tissue and blood samples in achalasia and controls using single-cell RNA sequencing (scRNA-seq).

Publication trends of peroral endoscopic myotomy during 2010-2022: a bibliometric analysis.

Background: Peroral endoscopic myotomy (POEM) has been rapidly accepted as a safe and effective therapy for achalasia and other esophageal motility disorders, and has inspired novel submucosal tunneling techniques. This study analyzed the trends in POEM research and compared contributions from different countries, regions, institutions, journals, and authors using bibliometric analysis to predict the trends and potential hotspots in POEM research.

Methods: Publications concerning POEM from January 1, 2010 to February 25, 2022, were extracted from the Web of Science database.

Endoscopic submucosal dissection for gastric adenocarcinoma of the fundic gland type (chief cell predominate type): Four years' experience from a tertiary hospital.

Objective: To summarize the endoscopic and clinicopathological features of gastric adenocarcinoma of the fundic gland type (GA-FG), and to evaluate the efficacy and safety of endoscopic submucosal dissection (ESD) for the treatment of GA-FGs.

Methods: From September 2017 to August 2021, patients treated with ESD who were pathologically confirmed to have GA-FGs were included. Those with lymphovascular and distal metastasis were excluded before ESD.

Utility of endoscopic ultrasound-guided fine-needle aspiration in pancreatic cancer patients who failed to obtain a pathological diagnosis in surgical exploration.

Background: Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) allows for the analysis of diagnostic tissue specimens from various regions. For pancreatic tumors, especially un-resectable ones, how to obtain pathological confirmation is important for determining sub-sequent treatment. The purpose of this study is to investigate the clinical utility of EUS-FNA in patients who failed to obtain a pathological diagnosis in surgical exploration.

Overexpression of fibrinogen-like protein 2 induces epithelial-to-mesenchymal transition and promotes tumor progression in colorectal carcinoma.

The main cause of death in colorectal carcinoma (CRC) patients is tumor metastasis; however, the underlying molecular mechanisms are largely unknown. In the present study, a novel metastasis-related gene, fibrinogen-like protein 2 (FGL2), was characterized for its role in CRC metastasis and underlying molecular mechanisms. The clinical significance of FGL2 was investigated using tissue microarray analysis of samples from 82 patients with CRC.

Long-term outcomes of peroral endoscopic myotomy for achalasia in pediatric patients: a prospective, single-center study.

Background: Peroral endoscopic myotomy (POEM) has been developed to provide a less-invasive myotomy for achalasia in adults but seldom has been used in pediatric patients.

Objective: To evaluate the feasibility, safety, and efficacy of POEM for pediatric patients with achalasia.

Design: Single-center, prospective study.

[Analysis of associated factors of lymph node metastasis in intramucosal early gastric cancer].

Objective: To analyze the associated predictive factors of lymph node metastasis in intramucosal early gastric cancer, and to provide reference for individualized treatment protocol.

Methods: Clinical data of 498 patients who were pathologically confirmed to be intramucosal early gastric cancer after radical resection of gastric cancer were retrospectively reviewed. Univariate and multivariate analyses were applied to evaluate the associated factors.

[Feasibility of endoscopic resection for gastric gastrointestinal stromal tumor].

In recent years, with the development of digestive endoscopy, endoscopic submucosal dissection(ESD) and its derived techniques including endoscopic submucosal excavation(ESE), submucosal tunnelling endoscopic resection(STER) and laparoscopic endoscopic combined surgery(LECS), can cure most of the gastric gastrointestinal stromal tumor(GIST). This article reviews the indication, method and evaluation of endoscopic resection for gastric GIST.
