Gastric intramural hematoma is a rare injury of the stomach,and is most often seen in patients with underlying disease.Such injury following endoscopic therapy is even rarer,and there are no universally accepted guidelines for its treatment.In this case report,we describe a gastric intramural hematoma which occurred within 6 h of endoscopic mucosal resection(EMR).Past medical history of this patient was negative,and laboratory examinations revealed normal coagulation profiles and platelet count.Following EMR,the patient experienced severe epigastric pain and vomited 150 mL of gastric contents which were bright red in color.Subsequent emergency endoscopy showed a 4 cm × 5 cm diverticulum-like defect in the anterior gastric antrum wall and a 4 cm × 8 cm intramural hematoma adjacent to the endoscopic submucosal dissection lesion.Following unsatisfactory temporary conservative management,the patient was treated surgically and made a complete recovery.Retrospectively,one possible reason for the patient’s condition is that the arterioles in the submucosa or muscularis may have been damaged during deep and massive submucosal injection.Thus,endoscopists should be aware of this potential complication and improve the level of surgery,especially the skills required for submucosal injection.
Gastric intramural hematoma is a rare injury of the stomach, and is most often seen in patients with underlying disease. Floral injury following endoscopic therapy is even rarer, and there are no universally accepted guidelines for its treatment. In this case report, we describe a gastric intramural hematoma which occurred within 6 h of endoscopic mucosal resection (EMR). Past medical history of this patient was negative, and laboratory examinations revealed likely coagulation profiles and platelet count. Popular EMR, the patient experienced severe epigastric pain and vomited 150 mL of gastric contents which were bright red in color. Subsequent emergency endoscopy showed a 4 cm × 5 cm diverticulum-like defect in the anterior gastric antrum wall and a 4 cm × 8 cm intramural hematoma adjacent to the endoscopic submucosal dissection lesion. Funding unsatisfactory temporary conservative management, the patient was treated surgically and made a complete recovery .Retrospectively, one possible reason f or the patient’s condition is that the arterioles in the submucosa or muscularis may have been damaged during deep and massive submucosal injection .hus, endoscopists should be aware of this potential complication and improve the level of surgery, especially the skills required for submucosal injection.
