We would like to report two cases of patients with acute fever who were seen and treated. Case 1: A male, 40 years old, developed nausea and vomiting after consuming a large amount of roasted lamb and drinking alcohol, accompanied by persistent high fever with temperature fluctuating from 39-40℃, accompanied by chills, chills and bilateral shoulder pain. He was admitted to the hospital with acute gastritis. Later, abdominal ultrasound indicated a huge liver abscess in the left lobe of the liver. After transferring to surgery for hepatic puncture and drainage, the symptoms were relieved. Case 2: A 38-year-old male with sudden onset of high fever, chills and diarrhea after consuming unfresh food. He was diagnosed with acute bacterial dysentery at the intestinal clinic and admitted to the Department of Infectious Diseases. Abdominal ultrasound and abdominal CT suggested hepatic abscess in the right lobe of the liver and edema in the gallbladder wall and bile duct wall. Since the abscess cavity had not yet formed, he was treated conservatively in the Infectious Diseases Department. After anti-infective treatment with high-dose triple cephalosporin combined with ornidazole, the body temperature gradually decreased to 38℃ only after 4 days, and the symptoms were relieved. The common feature of both patients was the discovery of liver abscess after the manifestation of gastrointestinal infection following the consumption of unclean diet. We are reminded to consider the possibility of liver abscess occurrence in patients with gastroenteritis who present with high fever that does not subside. There are two possible reasons for considering the occurrence of liver abscess; the first possibility: bacteremia resulting from GI infection, where bacteria are retained in the liver via blood circulation, leading to liver abscess; the second possibility: retrograde entry of bacteria into the liver via the biliary tract after GI infection, leading to liver abscess. Combined with the second patient who presented with edema of the gallbladder and bile duct wall, I prefer the second scenario. Since many people have a common opening of the pancreatic and bile ducts in the intestine, does this mean that pancreatitis or pancreatic abscesses may also occur in patients with intestinal infections? This question is worth thinking about!
