A183 UPPER GASTROINTESTINAL CAUSTIC INJURIES: A SINGLE CENTRE CASE SERIES
Notice bibliographique
Résumé
Abstract Background Caustic esophageal and gastric injury is a rare, but potentially lethal event. The 2017 American Association of Poison Control reported only 193,000 cases of caustic ingestion (1). Caustic agents are acidic or alkaline. The pH of the ingested substance dictates the type of injury and the area of the gastrointestinal track most at risk. The most common culprit agents are alkaline including, for example, bleaches, drain openers and dishwashing detergents. Due to the rarity and natural history of this disease there are very few high-quality studies for clinicians to refer to when managing these patients. Aims We present three cases of caustic ingestion and provide a review of current best practice standards. Methods Between August and September 2019, three patients were admitted to Sunnybrook Health Sciences Centre at the University of Toronto for caustic injury. All three patients were referred to the gastroenterology service and underwent an esophagogastroduodenoscopy (EGD) to assess the degree of esophageal and gastric injury. Patients were followed both in hospital and in the outpatient setting for ongoing surveillance and repeated endoscopic evaluation. Patient demographics, treatment, endoscopic findings and outcomes were collected. Results Three patients intentionally ingested caustic agents, were admitted to hospital and managed by the gastroenterology service. Patients were a mix of ages, genders and ethnicities. All ingestions were strong alkali agents including sodium hydroxide and sodium hypochlorite. All patients underwent an EGD within 24 hours of presentation and caustic injury was graded using the Zargar classification (2). All patients were started on intravenous proton pump inhibitor therapy. All patients were initially made nothing per mouth and ability to resume feeds was assessed based on symptoms. Patient 1, Zargar grade 1, was able to resume oral intake within 48 hours and progressed to a regular diet without complications. Patient 2, Zargar grade 2a, required 5 days of TPN and bowel rest after which a liquid diet was initiated and advanced without complications. The third patient, had a severe injury (Zargar grade 3b), requiring a prolonged hospital stay. He was on TPN for three weeks before transitioned to tube feeds. Conclusions Caustic mucosal injuries are an infrequent, but potentially lethal event requiring urgent assessment and management by a team including gastroenterologists, thoracic and abdominal surgeons, dieticians and intensivists. High-quality evidence to guide management of caustic injuries remains limited. In our case series, there was a wide spectrum of degree of mucosal injury. All 3 patients were managed in a consistent fashion based on current recommendations. Two of three cases had a rapid recovery with the ability to resume oral intake and return home. The third patient remains in hospital, requiring a high level of supportive care. Funding Agencies None

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
