A 61-year-old man with a 3-decade history of recurrent cholecystitis presented to the community emergency department with severe right upper quadrant pain. A CT scan was performed and revealed gangrenous cholecystitis with likely cholecystoduodenal fistulous communication.After discussion with the patient and the HPB team, the plan was made to attempt endoscopic extraction of the obstructing stone...

To explore high frequency electrocoagulation resection effect in treatment of patients with gastric polyps under painless gastroscopy. Sixty-four patients with gastric polyps were randomly divided into experimental group (32 cases) and control group (32 cases). Experimental group received basic treatment drugs for 8 weeks, and then treated with painless gastroscope high-frequency electrocoagulation resection. Control group was also given basic treatment drugs for 8 weeks, and then received high-frequency electrocoagulation resection under ordinary gastroscope...

BACKGROUND: At present, there is no unified and effective treatment for extreme corrosive esophageal stenosis (CES) with esophagotracheal fistula (ETF). This case had extreme and severe esophageal stenosis (ES) and ETF after ingesting an enzyme-based chemical detergent, resulting in a serious pulmonary infection and severe malnutrition. Upper gastrointestinal imaging showed that he had an ETF, and endoscopy showed that he had extreme and severe esophageal stricture. This case was complex and difficult to treat...

BACKGROUND: The majority of gastric neuroendocrine tumors (G-NENs) are present in various lesions under endoscopy, and they can be polypoid uplifts, submucosal tumors or papules, erosions, and ulcers. The lesions are mostly confined to the mucosal or submucosal layer, usually less than 2 cm, and exclusively localized to the gastric body or fundus. In type 1 G-NENs, about 22% of cases have no visible lesions under an endoscope, and such lesions can only be detected via biopsies (microcarcinoids)...

OBJECTIVES: The gut microbiota can mediate both pro and anti-inflammatory responses. In patients with psoriatic arthritis (PsA), we investigated the impact of faecal microbiota transplantation (FMT), relative to sham transplantation, on 92 inflammation-associated plasma proteins. METHODS: This study relates to the FLORA trial cohort, where 31 patients with moderate-to-high peripheral PsA disease activity, despite at least 3 months of methotrexate treatment, were included in a 26-week, double-blind, randomised, sham-controlled trial...

BACKGROUND: This meta-analysis was designed to compare the safety and efficiency of remimazolam with those of propofol in patients undergoing gastroscope sedation. METHODS: We searched PubMed, Cochrane Library, Embase, Ovid, Wanfang Database, China National Knowledge Infrastructure, SINOMED, and ClinicalTrials.gov for studies that reported on remimazolam versus propofol for gastroscope sedation from establishment to February 25, 2023. The sedative efficiency and the incidence of adverse events were assessed as outcomes...

BACKGROUND: One of the risk factors for esophageal adenocarcinoma is achalasia, an esophageal motility disorder that is typically treated surgically through laparotomy or laparoscopic surgery. The risk factors of gastric cardia cancer are also similar to esophageal adenocarcinoma due to the anatomical location of the gastric cardia close to the esophagus. There is currently no clinical evidence that achalching has a correlation with gastric cardia cancer. CASE SUMMARY: We report the case of an 85-year-old female patient was admitted to our department with dysphagia for 6 months...

OBJECTIVE: The aim of this study is to examine the distribution and features of gastroscopy in northern Xinjiang, a province in China. METHODS: We included a group of 895 patients diagnosed with digestive diseases at Urumqi Friendship Hospital and analyzed their gastroscopic results and baseline data. RESULTS: Among patients aged 12 to 86 years in the specified region, females exhibited a heightened susceptibility to esophageal-gastrointestinal and intestinal disorders compared to males...

BACKGROUND AND AIMS: Definitive peroral endoscopic treatment of pancreaticobiliary pathology in patients with surgically altered anatomy has recently been made more feasible by the use of lumen-apposing metal stents (LAMS) to create bowel-to-bowel anastomoses. We aim to demonstrate 4 cases of non–gastric bypass Roux-en-Y anatomy for which an enteroenterostomy was created under EUS guidance to facilitate complex peroral ERCP. METHODS: Akin to EUS-directed transgastric ERCP, the approach to EUS-directed transenteric ERCP involves identification and expansion of the target bowel before transmural puncture and stent placement...

BACKGROUND: There is need for the appropriate use of gastroscopy. OBJECTIVE: To determine the appropriateness of upper gastrointestinal endoscopy, and its association with significant endoscopy findings in our environment. METHODS: This was a prospective study of subjects who underwent gastroscopy at two centers in south-western Nigeria between August 2020 and August 2021. Indications were classified as either appropriate or inappropriate according to the ASGE guidelines, gastroscopic findings as either significant or not significant, patients as either elderly (≥ 60 years) or not, inpatients or outpatients, and referrals as either gastroenterologist referral, or not...

Most of the development of gastric disease prediction models has utilized pre-trained models from natural data, such as ImageNet, which lack knowledge of medical domains. This study proposes Gastro-BaseNet, a classification model trained using gastroscopic image data for abnormal gastric lesions. To prove performance, we compared transfer-learning based on two pre-trained models (Gastro-BaseNet and ImageNet) and two training methods (freeze and fine-tune modes). The effectiveness was verified in terms of classification at the image-level and patient-level, as well as the localization performance of lesions...

Background and study aims Adequacy of endoscope disinfection in resource-limited settings is unknown. Adenosine triphosphate (ATP) testing is useful for evaluation of endoscope reprocessing, and ATP <200 relative light units (RLUs) after manual endoscope cleaning has been associated with adequacy of endoscope disinfection. Methods Consecutive endoscopes undergoing reprocessing at five World Gastroenterology Organisation (WGO) training centers underwent ATP testing before and after an on-site educational intervention designed to optimize reprocessing practices...

BACKGROUND: To investigate the feasibility of a deformable self-assembled magnetic anastomosis ring (DSAMAR), designed and developed by us, for endoscopic gastrointestinal bypass anastomosis. METHODS: Ten experimental pigs were used as model animals. The DSAMAR comprises 10 trapezoidal magnetic units, arranged in a straight line under the constraint of a guide wire. When the desired anastomosis site is reached under the guidance of an endoscope, the catheter pushes the magnetic unit along the guide wire...

BACKGROUND: Ciprofol is a novel intravenous sedative and anesthetic. Studies have shown that it features a rapid onset of action, a fast recovery time, slight inhibition of respiratory and cardiovascular functions, and a low incidence of adverse reactions. This study aims to explore the median effective dose (ED50 ) and the 95% effective dose (ED95 ) of ciprofol in inhibiting responses to gastroscope insertion when combined with a low dose of alfentanil, and to evaluate its safety, to provide a reference for the rational use of ciprofol in clinical practices...

BACKGROUND: Gastric contents may contribute to patients' aspiration during anesthesia. Ultrasound can accurately assess the risk of gastric contents in patients undergoing sedative gastrointestinal endoscopy (GIE) procedures, but its efficiency is limited. Therefore, developing an accurate and efficient model to predict gastric contents in outpatients undergoing elective sedative GIE procedures is greatly desirable. METHODS: This study retrospectively analyzed 1501 patients undergoing sedative GIE procedures...

Video 1Narration of case and demonstration of the endoscopic management of an embedded stent with stent-in-stent technique to induce pressure necrosis, followed by a combination of needle-knife electroincision, argon plasma coagulation, stent intubation and transection with the gastroscope shaft, and cold and hot snare resection.

BACKGROUND: One challenging scenario in the treatment of biliary stricture is that post-liver transplantation (LT) biliary strictures cannot be accessed using endoscopic retrograde cholangiopancreatography (ERCP). Here, we report such a case that was successfully treated using a novel endoscopic technique. CASE SUMMARY: A 60-year-old man presented with obstructive jaundice caused by a post-LT biliary stricture. He underwent LT for compensated alcoholic liver cirrhosis and hepatocellular carcinoma...
