BACKGROUND: Long-term use of warfarin can provide benefits in the treatment of many diseases, but adverse bleeding events are unpreventable because of a narrow therapeutic range. OBJECTIVE: The aim of this retrospective chart review with data abstraction was to investigate the clinical presentations of intestinal intramural hemorrhage in emergency department (ED) patients. METHODS: We reviewed the cases of 17 patients with acute abdominal pain in our ED. Medical records including demographic data and results of abdominal computed tomography were retrospectively reviewed and analyzed. RESULTS: The mean ± SD age of the reviewed patients was 77.7 ± 8.5 years (range, 60-93 years). The mean ± SD duration from onset of symptoms to ED visit was 2.5 ± 1.3 days (range, 1-5 days). All patients had abdominal pain, and 64.7% had nausea/vomiting. A total of 64.7% of patients had peritoneal signs. The jejunum was most commonly involved (88.2% of all cases). The maximal mean ± SD wall thickening of the bowel was 14.1 ± 4.4 mm (range, 7.4-26.7 mm), and the estimated mean ± SD length was 35.6 ± 24.4 cm (range, 9-105 cm). The mean ± SD prothrombin time and activated partial thromboplastin time were prolonged to 86.5 ± 26.9 and 116.2 ± 43.1 seconds, respectively. All patients received medical treatment and survived. At the last follow-up (mean, 27.4 months), none of the patients had recurrence of intestinal intramural hemorrhage or intestinal obstruction. CONCLUSION: Prolonged prothrombin time and drug history can indicate the possibility of intramural intestinal hemorrhage, and abdominal computed tomography may help to exclude surgical diseases and prevent unnecessary surgery.
