On an unknown date, a patient in (b)(6) underwent a procedure for the placement of percutaneous endoscopic gastrostomy (peg) tube with jejunal (peg-j) tube.On (b)(6) 2020, the patient visited a hospital due to diarrhea and hematemesis.Marked anemia was noted, and hemorrhage of the digestive tract was suspected.On (b)(6) 2020, the patient had an endoscopy, but the j-tube blocked the view, so a diagnosis could not be made.On (b)(6) 2020, the patient visited a hospital again due to anemia, pyrexia, diarrhea and vomiting.On (b)(6) 2020, a hemoglobin level was drawn, with a result of 5g/dl.On (b)(6) 2020, a gastroscopy was performed, which showed an ulcer on the mucosa which was pressed by the j-tube the from stomach to the duodenum.During the gastroscopy, an attempt was made to remove the j-tube, but a knot was observed at the end of the tubing, so it could not be removed from the peg tube.During the procedure, an aneurysm and hemorrhage from the region were noted.The patient underwent coil embolization and remained hospitalized.The patient then became unconscious due to shock from decreased blood pressure.It was suspected that another region was hemorrhaging, so the physician performed another endoscopy.A second aneurysm was discovered, and the patient was treated with another coil embolization, then received a blood transfusion of 6000 cc and placed on a ventilator.On an unknown date, the j-tube was removed, and it was suspected that there might be a bezoar at the end of the tube, but it was not confirmed.Regarding massive hematemesis, the physician considered that the cause was a rupture of aneurysms which were pre-existing disease.The physician suspected that the ulcer was caused by the j-tube pulling distally and that the pulling of the tube also led to rupture of the aneurysms.
