We report a 14-year-old boy with alpha-fetoprotein-producing gastric cancer (AFPGC) who was found with ruptured metastatic tumor in the liver. AFPGC is exceedingly rare in pediatric age. It often shows metastases to the liver and should be included in differential diagnoses of liver tumors with increased serum AFP.

For ELBW neonates with bowel obstruction of unclear etiology, the early and frequent administration of a Gastrografin(®) enema is reasonable. Surgery should be considered if the obstruction lasts beyond approximately 14 days after birth.

Background: Oesophageal submucosal hematoma is a rare perioperative complication. When this complication develops after endovascular surgery, which requires postoperative antiplatelet therapy, whether to stop antiplatelet therapy or not is controversial. If antiplatelet therapy is discontinued, the appropriate time to resume antiplatelet therapy is unclear. Case presentation: A 75-year-old woman (height 134 cm, weight 37 kg) underwent flow diverter embolization for unruptured cerebral aneurysm under general anaesthesia. The patient received dual antiplatelet therapy before surgery and anticoagulation therapy intraoperatively. After surgery, the patient developed hematemesis and was diagnosed with oesophageal submucosal hematoma. Conservative treatment was initiated after discontinuing antiplatelet therapy, which was resumed 3 days after surgery. The patient showed good recovery even after the resumption of antiplatelet therapy. Conclusions: In our case, we successfully treated oesophageal submucosal hematoma developing after endovascular surgery with early resumption of postoperative antiplatelet therapy.
