Résumé
Abstract Background Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract and typically located in the stomach. Gastrointestinal bleeding is a frequent complication of GISTs with surgery being the treatment of choice. Managing GIST bleeding endoscopically can be challenging by an underlying friable neovascularization. The use of cyanoacrylate basis glue has well-established utility in the endoscopic management of variceal bleeding. However, the role of cyanoacrylate basis glue in the management of GIST bleeding is exceptionally rare. Aims We present a case of a bleeding GIST that was successfully managed through the utilization of cyanoacrylate basis glue allowing for elective surgical resection. Methods A chart review was undertaken. Also, a literature review of the topic was also conducted using the terms “GIST, Cyanoacrylate Glue, Bleeding” Results A 75-year-old male presented with a four week history of exertional chest pain. He had noticed persistent black stools for the previous two weeks. His past medical history was relevant for coronary artery disease; two years earlier he had drug eluting stents placed. His medications included ASA 81mg PO OD and Pantoprazole 40mg OD. Physical examination revealed stable vital signs, a soft abdomen and melena on rectal examination. Laboratory investigations showed a hemoglobin of 75 g/L, and 2 weeks prior his hemoglobin had been 120 g/L. Platelets were 149. His liver enzymes and liver function tests were unremarkable. His BUN was 9.9 mmol/L and creatinine of 96.0 umol/L. An esophagogastroduodenoscopy (EGD) revealed a 5cm smooth mass with a central deep depression, in the antrum, that was actively bleeding. Attempts to clip were unsuccessful due to the width of the central depression which was the source of bleeding. (See image 1). The endoscopist chose to inject 1cc of cyanoacrylate basis glue directly into the bleeding site. A subsequent CT scan revealed a 5.2cm polypoid mass in the gastric antrum, favored to be a GIST with no evidence of metastatic disease. Surgery and Cardiology were involved in the care of this patient, and emergency surgery was delayed due to the patient having an intercurrent acute coronary syndrome. Post EGD, the patient underwent an angiogram and the culprit coronary artery was stented and patient was started on dual antiplatelet therapy. Patient then successfully underwent a laparoscopic gastric wedge resection for his GIST, this was completed 1 week after EGD. The pathology of the resected area was in keeping with a GIST. Of note, the patient’s hemoglobin had been stable from the time of EGD until surgical intervention. Conclusions Managing GIST bleeding endoscopically can be challenging, and surgical resection is the recommended treatment modality. In situations where surgical intervention is contraindicated, endoscopic therapy with cyanoacrylate basis glue can be considered to achieve hemostasis in GIST bleeding. Funding Agencies None

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.
