Duodenal abscess is a form of phlegmonous enterocolitis and is a rarely reported
disease throughout the entire world. Duodenal abscess mostly develops from
complications of duodenal ulcer perforation, and may result in a clinically fatal
course because it is difficult to differentiate from some diseases such as gastric
ulcer, gastric cancer, hepatobiliary disorders etc.. The therapeutic gold standard is
surgical intervention including abscess removal and drainage. We experienced a
case
of duodenal abscess that expressed non-specific symptoms, weight loss and
epigastric pain, and diagnosed by gastrointestinal endoscopy, abdominal computed
tomography. We successfully treated it through surgical intervention with intravenous
antibiotics.
