gastrointestinal endoscopy

Fluoroscopy-guided gastrointestinal procedures, including gastrointestinal stenting, balloon-assisted endoscopy (BAE), endoscopic retrograde cholangiopancreatography (ERCP), and endoscopic ultrasound (EUS), are essential for diagnosis and treatment in gastroenterology. Such procedures involve radiation exposure that necessitates strict safety measures to protect patients, doctors, and medical staff. The April 2020 update to Japan's Ionizing Radiation Injury Prevention Regulations for occupational exposure reduced the lens exposure dose limit to approximately one-seventh of its previous level...

BACKGROUND: When pregnant patients present with nonobstetric pathology, the physicians caring for them may be uncertain about the optimal management strategy. The aim of this guideline is to develop evidence-based recommendations for pregnant patients presenting with common surgical pathologies including appendicitis, biliary disease, and inflammatory bowel disease (IBD). METHODS: The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) Guidelines Committee convened a working group to address these issues...

A woman in her 60s with anemia was diagnosed with a small intestinal intussusception on computed tomography. She underwent a double-balloon endoscopy, which revealed submucosal tumor in the ileum. Suspected to be the cause of anemia and intussusception, surgical intervention was carried out, revealing it to be a schwannoma. Schwannomas of the small intestine are very rare, and because exophytic growths are common, intussusception due to luminal side development is even rarer.

BACKGROUND AND AIMS: Many studies of gastric gastrointestinal stromal tumors (g-GISTs) following endoscopic resection (ER) have typically focused on tumor size, with most tumors at low risk of aggressiveness after risk stratification. There have been few systematic studies on the oncologic outcomes of intermediate- or high-risk g-GISTs after ER. METHODS: From January 2014 to January 2020, we retrospectively collected patients considered at intermediate- or high-risk of g-GISTs according to the modified NIH consensus classification system...

A girl in middle childhood was referred to the paediatric surgical team with acute colicky abdominal pain and bile-stained vomiting. This was preceded by a viral illness. Investigations revealed raised inflammatory markers, and imaging of the abdomen demonstrated ileal and jejunal thickening. Concerns were raised regarding whether she had inflammatory bowel disease. Endoscopy revealed gastritis and duodenitis, and colonoscopy was unremarkable. Video capsule endoscopy demonstrated ulcers in the jejunum and ileum...

A man in his late 50s presented with severe dysphagia caused by a complex refractory benign stenosis that was completely obstructing the middle oesophagus. The patient was unsatisfied with the gastrostomy tube placed via laparotomy as a long-term solution. Therefore, we performed robot-assisted minimally invasive oesophagectomy (video). Mobilisation of the stomach and gastric conduit preparation were more difficult due to the previously inserted gastrostomy tube; thus, the conduit blood supply was assessed using indocyanine green fluorescence...

BACKGROUND: The association between reflux esophagitis and pulmonary function remains controversial. Thus, evaluating the relationship between endoscopic reflux esophagitis and changes in pulmonary function over time in a nonsmoking population is an important clinical issue. METHODS: In this single-center retrospective cohort study, a medical examination database at Kameda Medical Center Makuhari was employed to identify nonsmokers who underwent upper gastrointestinal endoscopy and spirometry in 2010 and were followed up in 2015...

BACKGROUND: The treatment of patients with end-stage achalasia with a sigmoid-shaped esophagus is particularly challenging. A modified technique (pull-down technique) has been developed to straighten the esophageal axis, but only a limited number of studies on this topic are available in the literature. This study aimed to compare the outcome of patients who underwent the pull-down technique with that of patients who had a classical laparoscopic Heller-Dor (CLHD) myotomy. METHODS: All patients with a radiologic diagnosis of end-stage achalasia who underwent an LHD myotomy between 1995 and 2022 were considered eligible for the study...

Endoscopic ultrasound (EUS) is increasingly used as a therapeutic approach for gastrointestinal diseases, especially with the advent of lumen-apposing metal stents (LAMS). This has led to a rise in of EUS-guided gastrointestinal anastomosis procedures. Due to the reliability of intestinal conduits with LAMS, indications for EUS-guided gastrointestinal anastomosis are becoming more common and trend to potentially be standard care for gastric outlet obstruction, afferent loop syndrome, and EUS-directed transgastric interventions such as EUS-directed endoscopic retrograde cholangiopancreatography...

INTRODUCTION AND IMPORTANCE: Angiodysplasia, a prevalent vascular anomaly in the gastrointestinal tract, often presents with upper gastrointestinal bleeding, sharing symptoms with gastric varices. The diagnostic challenge arises due to overlapping clinical features. This case report highlights the importance of considering angiodysplasia in the differential diagnosis, especially when variceal bleeding is less likely, and emphasizes the role of various diagnostic modalities in accurate identification...

INTRODUCTION AND IMPORTANCE: Gastric leiomyosarcoma is a rare malignant tumor among the primary gastric carcinomas. Among the different common presentations, dysphagia is an uncommon presentation of gastric leiomyosarcoma. CASE PRESENTATION: A 29-year-old female presented with complaints of progressive dysphagia for 1 year associated with vomiting, significant weight loss, and anorexia for 6 months. On blood investigations, she had anemia, hypokalemia, prerenal acute kidney injury, and unconjugated hyperbilirubinemia...

BACKGROUND AND AIMS: The rapid urease test (RUT) is widely used to detect Helicobacter pylori (H. pylori) infection; however, it is not preferred as a monitoring strategy following eradication owing to its low sensitivity. In this study, we evaluated the diagnostic performance of RUT using the sweeping method, which overcomes the limitations of conventional tissue sampling methods following eradication. METHODS: Patients who received H. pylori eradication treatment were enrolled...

BACKGROUND AND AIMS: Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) promote weight loss by suppressing appetite, enhancing satiety, regulating glucose metabolism and delaying gastric motility. We sought to determine whether GLP-1 RA use could impact sedated medical procedures like esophagogastroduodenoscopy (EGD). METHODS: We conducted a retrospective study on 35,183 patients who underwent EGD between 2019 and 2023, 922 of which were using a GLP-1-RA. Data were collected regarding demographics, diabetes status, retained gastric contents during EGD (RGC), incidence of aborted EGD, and necessity for repeat EGD...

BACKGROUND AND AIMS: Studies have shown that hydrothermal duodenal mucosal ablation results in improved glycemic control. Re-Cellularization via Electroporation Therapy (ReCET) is a novel endoscopic procedure that uses electroporation to induce cellular apoptosis and subsequent reepithelization. In this study, we aimed to eliminate exogenous insulin treatment in T2D patients through a single ReCET procedure combined with a GLP-1 receptor agonist (GLP-1RA). Feasibility, safety, and (dose) efficacy of ReCET were assessed...

BACKGROUND AND AIMS: Lymph node metastasis significantly affects the prognosis of early gastric cancer patients. Endoscopic ultrasonography (EUS) plays a crucial role in the preoperative assessment of early gastric cancer. This study evaluated the efficacy of EUS in identifying lymph node metastasis in early gastric cancer patients and developed a risk score model to aid in choosing the best treatment options. METHODS: We retrospectively analyzed the effectiveness of EUS for detecting lymph node metastasis in early gastric cancer patients...

BACKGROUND AND AIMS: While endoscopic ultrasound(EUS) is highly accurate for the evaluation of common bile duct (CBD) dilation, the yield of EUS in patients with incidental CBD dilation is unclear. METHODS: Serial patients undergoing EUS for incidental, dilated CBD (per radiologist, minimum >6mm objectively) from two academic medical centers, without active pancreaticobiliary disease or significantly elevated LFTs were evaluated. Multivariable logistic regression identified predictors of EUS with significant findings and a novel prediction model was derived from one center, internally validated with bootstrapping, and externally validated at the second center...
