Gi endoscopy and gi procedures

Background and study aims Endoscopic retrograde cholangiopancreatography (ERCP) poses the risk of radiation exposure (RE) to patients and staff and increases the risk of adverse biological effects such as cataracts, sterility, and cancer. Newer fluoroscopy equipment (C-Arm) provides options to limit radiation in the form of lower radiation dose and frame rate or time-limited "pulsed" settings. However, the impact of lower settings on image quality has not been assessed, and no standard protocol exists for fluoroscopy settings used during ERCP...

In 2000, the small bowel capsule revolutionized the management of patients with small bowel disorders. Currently, the technological development achieved by the new models of double-headed endoscopic capsules, as miniaturized devices to evaluate the small bowel and colon [pan-intestinal capsule endoscopy (PCE)], makes this non-invasive procedure a disruptive concept for the management of patients with digestive disorders. This technology is expected to identify which patients will require conventional invasive endoscopic procedures (colonoscopy or balloon-assisted enteroscopy), based on the lesions detected by the capsule, i...

Endoscopic hand suturing (EHS) was first developed to firmly close a mucosal defect following endoscopic submucosal dissection and has the potential for expanded applications. This study aimed to investigate the feasibility and safety of EHS in various clinical settings. In this single-center pilot study, 15 patients who had diseases with potential indications for EHS were prospectively recruited. Technical success, clinical success after the procedure, and severe EHS-related adverse events (AEs) were evaluated...

The number and variety of applications of artificial intelligence (AI) in gastrointestinal (GI) endoscopy is growing rapidly. New technologies based on machine learning (ML) and convolutional neural networks (CNNs) are at various stages of development and deployment to assist patients and endoscopists in preparing for endoscopic procedures, in detection, diagnosis and classification of pathology during endoscopy and in confirmation of key performance indicators. Platforms based on ML and CNNs require regulatory approval as medical devices...

Pseudoaneurysms are rare but potentially life-threatening complications that may occur after surgical procedures. This report presents the case of a 28-year-old woman who developed a pseudoaneurysm in the Left Inferior Phrenic Artery (LIPA) following a Laparoscopic Sleeve Gastrectomy (LSG). The complication manifested as severe gastrointestinal bleeding. Upper GI Endoscopy and multislice CT scan, repeated twice, failed to localize the bleeding source to treat it. Successful endovascular embolization using a Glue/Lipidol mixture was achieved despite difficulties in localizing the pseudoaneurysm, resulting in immediate symptomatic relief and avoiding surgical intervention...

BACKGROUND: Open-access oesophagogastroduodenoscopy (OAO) is defined as the performance of oesophagogastroduodenoscopy (OGD) requested by referring physicians without a prior specialist consultation. With the increasing demand for specialist appointments, the use of OAO has helped to reduce healthcare utilization by decreasing prior clinic visits. This also allows endoscopies to be scheduled and performed earlier. This study aims to evaluate our experience in providing OAO services to patients with non-alarming dyspepsia symptoms under the age of 60...

INTRODUCTION: Dieulafoy's lesion (DL) is a vascular malformation that can lead to massive gastrointestinal bleeding. It's usually found in the stomach. However, DL's occurrence in atypical sites such as the small bowel and colon is exceptionally rare, posing significant management challenges. CASE PRESENTATION: In this report, we present two cases of DL occurring in uncommon sites, each managed with distinct approaches. Case 1 is a 50-year-old man admitted to the emergency department due to massive GI bleeding and hemodynamic instability...

Several cases have been reported that suggest the efficacy of gel immersion endoscopic mucosal resection (GI-EMR) for gastric neoplasms. However, no study has evaluated treatment outcomes of GI-EMR for gastric neoplasms. This study aimed to investigate the efficacy and safety of GI-EMR for early gastric neoplasms. Nine patients (17 lesions) undergoing gastric GI-EMR were included, with a median lesion size of 10 mm (interquartile range [IQR] 5-13 mm). All lesions were protruding or flat elevated. The median procedure time was 3 minutes (IQR 2-5) and en bloc resection was achieved in all cases...

Background and study aims Reprocessing reusable endoscopes is challenging due to their non-sterilizable nature. Disinfection has been shown to have a significant risk of failure with serious consequences. Single-use endoscopes can eliminate contamination risk and reduce workflow delays caused by reprocessing. This study evaluated the clinical performance of single-use gastroscopes in patients undergoing esophagogastroduodenoscopy (EGD). Patients and methods In this case series, 60 patients underwent EGD using single-use gastroscopes, with 34 procedures in the endoscopy department and 26 in the intensive care unit...

Unsedated transnasal endoscopy (TNE) is an alternative method of examining the esophageal mucosa in pediatric patients with eosinophilic esophagitis (EoE), reducing cost, time, and risk associated with frequent surveillance esophagogastroduodenoscopies (EGD). Adequacy of transnasal esophageal biopsies for the evaluation of eosinophilic esophagitis histologic scoring system (EoEHSS) has not yet been evaluated. We compared procedure times, endoscopic findings, and EoEHSS scoring for EoE patients undergoing TNE versus standard EGD...

Integrating artificial intelligence (AI) into gastrointestinal (GI) endoscopy heralds a significant leap forward in managing GI disorders. AI-enabled applications, such as computer-aided detection and computer-aided diagnosis, have significantly advanced GI endoscopy, improving early detection, diagnosis and personalized treatment planning. AI algorithms have shown promise in the analysis of endoscopic data, critical in conditions with traditionally low diagnostic sensitivity, such as indeterminate biliary strictures and pancreatic cancer...

Endoscopy, a widely used medical procedure for examining the gastrointestinal (GI) tract to detect potential disorders, poses challenges in manual diagnosis due to non-specific symptoms and difficulties in accessing affected areas. While supervised machine learning models have proven effective in assisting clinical diagnosis of GI disorders, the scarcity of image-label pairs created by medical experts limits their availability. To address these limitations, we propose a curriculum self-supervised learning framework inspired by human curriculum learning...

Gastrointestinal (GI) tract disorders are a significant public health issue. They are becoming more common and can cause serious health problems and high healthcare costs. Small bowel tumours (SBTs) and colorectal cancer (CRC) are both becoming more prevalent, especially among younger adults. Early detection and removal of polyps (precursors of malignancy) is essential for prevention. Wireless Capsule Endoscopy (WCE) is a procedure that utilises swallowable camera devices that capture images of the GI tract...

Obesity is an important public health concern worldwide. In Saudi Arabia, the overall prevalence of obesity has increased in both men and women in recent decades. The laparoscopic approach to bariatric surgery was first reported in the 1990s, with laparoscopic adjustable gastric banding (LAGB) developed soon after. The performance of bariatric procedures has increased rapidly in recent years, with safety and efficacy data available for the surgical treatment of obesity and related metabolic disorders. Herein, we report a challenging condition of a female patient who underwent LAGB insertion in 2013...

Dieulafoy lesions (DL) are an uncommon cause of gastrointestinal bleeding which is often difficult to diagnose due to the rarity of the condition and varying clinical presentations. This case describes an unusual presentation of upper gastrointestinal bleeding in an 85-year-old female with findings on two separate gastroscopies of both a gastric ulcer and duodenal DL. The pathophysiology of DL remains poorly understood and despite shared risk factors, these two pathologies are rarely reported concurrently. The presence of a concomitant gastric ulcer further complicated the diagnosis and treatment of the duodenal DL in this case...

BACKGROUND: Gastrointestinal bleeding (GIB) is common in left ventricular assist devices (LVADs) patients, but the optimal screening approach before LVAD implantation is still unclear. The aim of the study was to describe our experience with pre- and post-LVAD implantation endoscopic screening and subsequent GI bleeding in this cohort. METHODS: A retrospective review was conducted among all patients who underwent LVAD implantation at Saint Luke's Hospital, between 2010 and 2020...

INTRODUCTION: Krukenberg tumors account for 9 % of metastatic ovarian tumors, they usually originate from the stomach and colon and are microscopically characterized by the presence of mucus-filled signet-ring cells. Krukenberg tumor originating from the gastroesophageal junction is extremely rare, which limits establishing proper diagnosis and management. PRESENTATION OF CASE: A 34-year-old women presented with a complaint of amenorrhea, ultrasonography showed bilateral ovarian masses, pathological studies revealed Krukenberg tumor, immunohistochemistry of the tumor was positive for (CK1, and CK20)...

BACKGROUND/AIMS: Few multicenter studies have investigated the efficacy of hemostatic powders in gastrointestinal (GI) bleeding. We aimed to investigate the clinical outcomes of hemostatic powder therapy and the independent factors affecting rebleeding rates. METHODS: We retrospectively recruited patients who underwent a new hemostatic adhesive powder (UI-EWD; Next-Biomedical) treatment for upper and lower GI bleeding between January 1, 2020 and March 1, 2023. We collected patients' medical records and bleeding lesions...

Background and study aims Endoscopic hemostasis is a life-saving procedure for gastrointestinal bleeding; however, training for it is often performed on real patients and during urgent situations that put patients at risk. Reports of simulation-based training models for endoscopic hemostasis are scarce. Herein, we developed a novel simulator called "Medical Rising STAR-Ulcer type" to practice endoscopic hemostasis with hemoclips and coagulation graspers. This study aimed to evaluate the reproducibility of the clinical difficulty of this model and the effectiveness of simulation-based training for clipping hemostasis...
