Severe hypophosphataemia and hypocalcaemia following intravenous ferric derisomaltose and denosumab administration.

Serum calcium and phosphorus levels are tightly regulated by the calciotropic hormone parathyroid hormone, fibroblast growth factor 23 and 1,25(OH) vitamin D. Commonly prescribed therapies for iron-deficiency anaemia (IDA) such as ferric carboxymaltose and ferric derisomaltose (FDM) have been shown to disrupt phosphorus homeostasis, resulting in hypophosphataemia. Similarly, denosumab use can result in hypocalcaemia due to the inhibition of osteoclastic maturation, activity and survival.

EUS-guided gastroenterostomy vs. surgical gastrojejunostomy and enteral stenting for malignant gastric outlet obstruction: a meta-analysis.

Malignant gastric outlet obstruction (MGOO) is traditionally treated with surgical gastrojejunostomy (SGJ), which is effective but associated with high rates of morbidity, or endoscopic stenting (ES), which is less invasive but associated with significant risk of stent dysfunction and need for reintervention. Endoscopic ultrasound-guided gastroenterostomy (EUS-GE) provides a robust bypass without the invasiveness of surgery. We performed a systematic review and meta-analysis comparing EUS-GE to SGJ and ES for MGOO.

A Simple Admission Order-set Improves Adherence to Canadian Guidelines for Hospitalized Patients With Severe Ulcerative Colitis.

Background: Individuals hospitalized with severe ulcerative colitis represent a complex group of patients. Variation exists in the quality of care of admitted patients with inflammatory bowel disease. We hypothesized that implementation of a standardized admission order set could result in improved adherence to current best practice guidelines (Toronto Consensus Statements) for the management of this patient population.

EUS-guided celiac plexus neurolysis for pancreas cancer - Finally established or still under review?

Patients with pancreas cancer must deal frequently with intractable and refractory pain. Endoscopic ultrasound guided-celiac plexus neurolysis (EUS-CPN) has been the most studied and used therapeutic technique aimed to destroy the pain fibres that allow the pancreas to communicate with the central nervous system. A neurolytic agent, most commonly ethanol, is optimally spread around the celiac axis in order to reduce pain and mitigate narcotic requirements.

Pan-Esophageal Submucosal Dissection following Transesophageal Echocardiography.

A 73-year-old female underwent open mitral valve replacement with transesophageal echocardiography (TEE) guidance. She developed upper gastrointestinal bleeding postoperatively and was found on upper endoscopy to have a bleeding site at the gastric cardia with the appearance of focal trauma and a possible puncture site. A submucosal bluish protrusion was seen throughout the esophagus with a mucosal flap at the proximal esophagus.

Fucosyltransferase 2 Mutations Are Associated With a Favorable Clinical Course in Crohn's Disease.

Background: Fucosyltransferase 2 (FUT2) participates in intestinal antigen secretion and bacterial adherence. FUT2 homozygous nonsense mutations (FUT2M) and subsequent nonsecretor status is associated with Crohn's disease (CD). The common null allele is rs601338.

Endoscopic ultrasound (EUS)-guided fine needle biopsy alone vs. EUS-guided fine needle aspiration with rapid onsite evaluation in pancreatic lesions: a multicenter randomized trial.

Background: Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is the standard in the diagnosis of solid pancreatic lesions, in particular when combined with rapid onsite evaluation of cytopathology (ROSE). More recently, a fork-tip needle for core biopsy (FNB) has been shown to be associated with excellent diagnostic yield. EUS-FNB alone has however not been compared with EUS-FNA + ROSE in a large clinical trial.

A randomized noninferiority trial comparing the diagnostic yield of the 25G ProCore needle to the standard 25G needle in suspicious pancreatic lesions.

Background And Objectives: The aim of the study was to perform the first randomized trial comparing the diagnostic yield, bloodiness, and cellularity of the 25G standard needle (25S) and the 25G ProCore™ needle (25P).

Materials And Methods: All patients referred to the tertiary care referral center for EUS guided fine-needle aspiration (EUS-FNA) of suspicious solid pancreatic lesions were eligible. EUS-FNA was performed in each lesion with both 25S and 25P needles (the choice of the first needle was randomized), using a multipass sampling pattern, without stylet or suction.

A proposal for the ideal algorithm for the diagnosis, staging, and treatment of pancreas masses suspicious for pancreatic adenocarcinoma: Results of a working group of the Canadian Society for Endoscopic Ultrasound.

Numerous clinical pathways exist for patients presenting with a suspicious pancreatic mass. These range from direct surgical intervention following staging, with preoperative cross-sectional imaging, EUS with or without fine-needle aspiration or fine-needle core biopsy; neoadjuvant chemotherapy and/or radiation therapy; or palliation. Although international guidelines exist for pancreas cancer management, the ideal workup and treatment for a suspicious pancreas mass is unclear.

Endoscopist-Directed Propofol as an Adjunct to Standard Sedation: A Canadian Experience.

Background: Sedation practices vary widely by region. In Canada, endoscopist-directed administration of a combination of fentanyl and midazolam is standard practice. A minority of cases are performed with propofol.

TC-325 hemostatic powder versus current standard of care in managing malignant GI bleeding: a pilot randomized clinical trial.

Background And Aims: TC-325 (Hemospray; Cook Medical, Winston-Salem, NC, USA), an endoscopic hemostatic powder, exhibits possible benefits in patients with malignant GI bleeding. Our aim is to assess feasibility and determine estimates of efficacy of TC-325 compared with standard of care (SOC) in terms of initial hemostasis and recurrent bleeding rates in comparable groups of patients with malignant GI bleeding.

Methods: Adult patients presenting with acute malignant upper or lower GI bleeding were randomized to TC-325 or SOC.

High-Dose Infliximab Rescue Therapy for Hospitalized Acute Severe Ulcerative Colitis Does Not Improve Colectomy-Free Survival.

Background And Objective: Optimization strategies with infliximab (IFX) are increasingly used as rescue therapy for steroid refractory acute severe ulcerative colitis (ASUC). We aim to determine if intensified IFX induction improves colectomy rate and identifies outcome predictors.

Methods: Hospitalized adult patients who received IFX for ASUC between 2010 and 2016 were identified.

Endoscopic Ultrasound-Guided Management of Pain in Chronic Pancreatitis and Pancreatic Cancer: an Update.

Opinion Statement: PURPOSE OF REVIEW: Unrelenting pain from chronic pancreatitis (CP) and pancreatic cancer (PC) remain clinical challenges for the physician and a significant cause of decreased quality of life for the patient. Endoscopic ultrasound (EUS)-guided therapy for each condition is distinct and builds on the endosonographer's straightforward access to the celiac axis.

Recent Findings: Over the past 20 years, generally small studies of modest methodology have surfaced for both EUS-guided celiac plexus block (CPB) and celiac plexus neurolysis (CPN).

Practice guidelines for endoscopic ultrasound-guided celiac plexus neurolysis.

Objectives: The objective of guideline was to provide clear and relevant consensus statements to form a practical guideline for clinicians on the indications, optimal technique, safety and efficacy of endoscopic ultrasound guided celiac plexus neurolysis (EUS-CPN).

Methods: Six important clinical questions were determined regarding EUS-CPN. Following a detailed literature review, 6 statements were proposed attempting to answer those questions.

Onsite evaluation of endoscopic ultrasound fine needle aspiration: the endosonographer, the cytotechnologist and the cytopathologist.

Endoscopic ultrasound guided fine needle aspiration (EUS-FNA) has become an essential tool in the management of multiple diseases. Its accuracy is related to different aspects of the technique, one of the most important being the experience and interaction of the endosonographer and pathologist. Certain studies over the past years have highlighted the importance of having rapid on-site evaluation (ROSE) of samples obtained at the time of EUS-FNA.

Prevalence and predictors of sleep disturbance among liver diseases in long-term transplant survivors.

Background: Patients with cirrhosis are known to experience sleep disturbance, which negatively impacts health-related quality of life.

Objective: To assess the prevalence and predictors of sleep disturbance before and after liver transplantation (LT).

Methods: Both pre- and post-LT patients were administered the Basic Nordic Sleep Questionnaire.

Can the presence of endoscopic high-risk stigmata be predicted before endoscopy? A multivariable analysis using the RUGBE database.

Background: Many aspects in the management of acute upper gastrointestinal bleeding rely on pre-esophagogastroduodenoscopy (EGD) stratification of patients likely to exhibit high-risk stigmata (HRS); however, data predicting the presence of HRS are lacking.

Objective: To determine clinical and laboratory predictors of HRS at the index EGD in patients presenting with acute upper gastrointestinal bleeding using retrospective data from a validated national database - the Canadian Registry in Upper Gastrointestinal Bleeding and Endoscopy registry. methods: Relevant clinical and laboratory parameters were evaluated.

Accuracy of biopsies for Helicobacter pylori in the presence of intestinal metaplasia of the stomach.

Background/aims: Gastric cancer is the second leading cause of cancer-related death worldwide. The majority of gastric cancers is "intestinal-type" adenocarcinoma, caused in part by H. pylori infection.

Sengstaken-Blakemore tube for non-variceal distal esophageal bleeding refractory to endoscopic treatment: a case report & review of the literature.

Non-variceal upper-gastrointestinal bleeding (NVUGIB) refractory to therapeutic endoscopy is a challenging situation. The following details a novel use for the Sengstaken-Blakemore tube in a case of severe ulcerative esophagitis after failure of conventional medical and endoscopic treatment. A 77-year-old man with a history of peptic ulcer disease developed massive hematemesis during a hospital admission.

Celiac plexus neurolysis in the management of unresectable pancreatic cancer: when and how?

Pancreatic cancer is the second most common abdominal cancer in North America with an estimated 20% resectability at diagnosis, and overall 5-year survival of 5%. Pain is common in pancreatic cancer patients with 70%-80% suffering substantial pain. Celiac plexus neurolysis (CPN) is a technique that can potentially improve pain control in pancreatic cancer while preventing further escalation of opioid consumption.
