Lower abdominal surgery
Pharmacological prophylaxis was not routinely administrated following gastroenterological surgery because of concerns about bleeding complications. We tried to establish the original risk classification to determine the indication for pharmacological prophylaxis for selected patients at high risk of venous thromboembolism (VTE). One hundred and fifty-six consecutive patients who underwent lower abdominal elective surgery were divided into three groups (highest, high, and low risk groups) based on the original risk classification. Pharmacological prophylaxis was indicated for patients in the highest and high risk groups. We investigated safety and efficacy of the pharmacological prophylaxis based on this classification. Sixteen patients were classified in the highest, 50 in the high, and 90 in the low risk groups. Pharmacological prophylaxis was used for 59 cases (37.8%). There was no symptomatic pulmonary embolism or major bleeding complications. There were no significant differences in the occurrence of postoperative complications, analgesia use, and median postoperative pain scores for the three groups. In the highest and high risk groups administrated pharmacological prophylaxis, fibrin degradation products (FDP) and D-dimer did not change between postoperative day 1 and day 7. These data suggested the clinical significance of the pharmacological prophylaxis based on the original risk classification.
