A 55-year-old man with a history of pancreatic cancer surgery and was undergoing chemotherapy presented with high fever. A computed tomography scan revealed a liver abscess at the location of a previously identified hemangioma. PTAD was performed, and contrast imaging revealed a connection with the bile duct. Edwardsiella tarda was detected in the abscess culture. Hemangioma-related abscess formation is extremely rare, with no reported cases of E. tarda detection in such abscesses.
Herein, we report a case of a man with a large symptomatic hepatic cyst that gradually enlarged over a follow-up period of 15 years, which eventually caused epigastric fullness and obstructive jaundice. The patient underwent percutaneous cystic drainage followed by sclerotherapy using minocycline hydrochloride combined with intracystic lavage. The treatment resulted in a significant reduction in the hepatic cyst size, symptom improvement, and absence of recurrence for 670 days.
A 40-year-old woman was admitted to our hospital by ambulance due to accidental ingestion of 100ml of 35% hydrogen peroxide. Although the patient suffered from frequent vomiting, abdominal distension, and abdominal pain, signs of peritonitis were not observed. An abdominal computed tomography examination demonstrated obvious gas images in the gastric wall and intrahepatic portal veins. Upper gastrointestinal endoscopy revealed mucosal redness, swelling, and erosion from the lower part of the esophagus to the duodenum. Portal venous gas and upper gastrointestinal mucosal injury due to accidental hydrogen peroxide ingestion were suspected. As the vital signs were stable and there were no signs peritoneal irritation or neurological symptoms, she was treated medically with vonoprazan, rebamipide, and sodium alginate. The next day, abdominal symptoms immediately improved and 3 days later, hepatic portal venous gas had disappeared on ultrasonography. She was discharged on the 5th day after admission. Two months later, upper gastrointestinal endoscopy showed improvement in inflammatory findings. We report a remarkable case of hepatic portal venous gas and upper gastrointestinal mucosal injury and elucidate the endoscopic findings associated with hydrogen peroxide ingestion.
