Purpose: To examine the treatment outcome for patients with acute bleeding from the lower gastrointestinal tract requiring transfusion and acute surgical care as a function of various risk factors
Materials and methods: Between 1999 and 2007, we collected data on 59 patients (39 male and 20 female patients) who received surgical intervention for acute lower intestinal hemorrhage requiring transfusion at our university clinic. Treatment complications and mortality were analyzed retrospectively.
Results: The average age of the patients in this study is 70.0 +/- 12.2 years (range, 39 to 97 years) with an overall mortality of 15.3%. Blood transfusions >10 U (p = 0.031), postoperative need for ventilation (p = 0.004), necessary reoperations (p = 0.016), and an initial hemoglobin level <80 g/L (p = 0.043) proved to be significant risk factors for death. Blood transfusions >10 U (p = 0.028), necessary reoperations (p = 0.001), and an initial hemoglobin level <80 g/L (p = 0.033) were found to be significant risk factors for postoperative complications. All other parameters have no significant impact.
Conclusions: The decisive factors for the outcome of lower gastrointestinal hemorrhage requiring surgery are the severity of bleeding, beginning of treatment (initial hemoglobin level, need for packed red blood cells), and treatment efficiency (necessary reoperation).
