Article Synopsis
- The study evaluated a new disposable esophagogastroduodenoscopy (EGD) system aimed at preventing cross-infection in medical settings, testing its feasibility and safety in 30 patients during emergencies and surgeries.
- All procedures using the disposable EGD were successful, with a 100% technical success rate, and no device malfunctions or adverse events reported.
- The results suggest that the disposable EGD is a safe and effective alternative to traditional EGDs, demonstrating good image quality and efficient procedure times in critical situations.
To overcome difficulties in the removal of duodenal bulb lesions, especially those in anatomically challenging locations, we developed the endoscopic resection via antral submucosal tunneling (ERAST) technique. In this study, we evaluated the feasibility and safety of ERAST for the removal of superficial and subepithelial lesions in the duodenal bulb. This was a single-center retrospective study of 10 patients with lesions in the bulb.

Methods: This was a prospective multicenter, blinded study that compared SMCE with gastroscopy in patients from April 2018 to July 2018. All patients first underwent SMCE and then subsequently had gastroscopy with i.
Objectives: Flat colorectal adenomas have a high risk of malignancy; however, their detection is often difficult due to their flat morphology. In this retrospective, large-scale study, we investigated the prevalence and characteristics of flat adenomas in a population in China.
Methods: We analyzed the data collected for 16951 consecutive patients who underwent colonoscopy at four participating hospitals between September 2013 and September 2015.
Effectiveness and safety of endoscopic resection for gastric GISTs: a systematic review.
Minim Invasive Ther Allied Technol
June 2018
Aims: To evaluate the effectiveness and safety of endoscopic resection for gastric gastrointestinal stromal tumors (GISTs).
Material And Methods: The effectiveness and safety of endoscopic resection were mainly assessed by complete resection rate, postoperative adverse event rate, and recurrence rate. Moreover, a comparison of endoscopic with laparoscopic resection for gastric GISTs was made through weighted mean difference by STATA 12.
Background And Aims: Endoscopic submucosal tunneling dissection (ESTD) has been proved to be safe and effective for removal of esophageal submucosal tumors (SMTs) and can maintain the mucosal integrity compared with other endoscopic methods. The aim of the study was to estimate the safety and efficacy of ESTD as well as compare its efficacy with thoracoscopic enucleation for esophageal SMTs, which is used increasingly as a minimally invasive approach.
Methods: We retrospectively collected the clinical data of patients with esophageal SMTs <40 mm who underwent ESTD or thoracoscopic enucleation at Nanfang Hospital between January 2008 and August 2016.
Objective: Patency capsule (PC) is a tool to screen the patency of the gastrointestinal (GI) tract. Capsule endoscopy can be performed after the patency is confirmed by the patency capsule. We aimed to estimate the diagnostic value of PC based on the existing trials.

Methods: Rheb gene was amplified by PCR to construct the recombinant plasmid LV31-Rheb-WT and LV31-Rheb-D60K. HEK-293 FT cells were contransfected with the recombinant lentiviral vector together with a lentiviral package plasmid to produce the lentiviral particles.
