Insights
This study found that continuing aspirin therapy during elective hepatectomy (liver surgery) did not increase bleeding risks. Patients on aspirin had similar outcomes to those not on the medication, suggesting it is safe for liver surgery.
Area of Science:
- Hepatobiliary Surgery
- Cardiovascular Pharmacology
- Surgical Oncology
Background:
- The safety of continuing antiplatelet therapy, specifically aspirin, during hepatectomy is not well-established.
- Elective liver resections carry inherent risks, and the impact of perioperative aspirin use requires investigation.
Purpose of the Study:
- To evaluate the operative risks associated with continuing aspirin therapy during elective hepatectomy.
- To compare bleeding-related complications and other adverse events in patients undergoing liver surgery with or without aspirin.
Main Methods:
- A multicentre prospective observational study compared patients undergoing elective hepatectomy with and without aspirin continuation.
- Propensity score (PS) matching was employed to create balanced cohorts for analysis.
- Outcomes assessed included severe hemorrhage (Dindo-Clavien grade IIIa or higher), transfusion rates, morbidity, complication scores, and mortality.
Main Results:
- After PS matching, 108 patients were in each group (aspirin vs. control).
- No significant differences were observed in severe hemorrhage (6.5% vs. 5.6%), intraoperative transfusion, overall hemorrhage, Comprehensive Complication Index (CCI) score, major complications, or 90-day mortality between the groups.
- While major complications appeared higher in the aspirin group (23.1% vs. 13.9%), this did not reach statistical significance.
Conclusions:
- Continuation of aspirin therapy does not appear to be associated with an increased risk of bleeding complications after elective hepatectomy.
- This finding suggests that aspirin can be safely continued in patients undergoing elective liver surgery, provided other risk factors are managed.
Background:
The operative risk of hepatectomy under antiplatelet therapy is unknown. This study sought to assess the outcomes of elective hepatectomy performed with or without aspirin continuation in a well balanced matched cohort.
Methods:
Data were retrieved from a multicentre prospective observational study. Aspirin and control groups were compared by non-standardized methods and by propensity score (PS) matching analysis. The main outcome was severe (Dindo-Clavien grade IIIa or more) haemorrhage. Other outcomes analysed were intraoperative transfusion, overall haemorrhage, major morbidity, comprehensive complication index (CCI) score, thromboembolic complications, ischaemic complications and mortality.
Results:
Before matching, there were 118 patients in the aspirin group and 1685 in the control group. ASA fitness grade, cardiovascular disease, previous history of angina pectoris, angioplasty, diabetes, use of vitamin K antagonists, cirrhosis and type of hepatectomy were significantly different between the groups. After PS matching, 108 patients were included in each group. There were no statistically significant differences between the aspirin and control groups in severe haemorrhage (6·5 versus 5·6 per cent respectively; odds ratio (OR) 1·18, 95 per cent c.i. 0·38 to 3·62), intraoperative transfusion (23·4 versus 23·7 per cent; OR 0·98, 0·51 to 1·87), overall haemorrhage (10·2 versus 12·0 per cent; OR 0·83, 0·35 to 1·94), CCI score (24 versus 28; P = 0·520), major complications (23·1 versus 13·9 per cent; OR 1·82, 0·92 to 3·79) and 90-day mortality (5·6 versus 4·6 per cent; OR 1·21, 0·36 to 4·09).
Conclusion:
This observational study suggested that aspirin continuation is not associated with a higher rate of bleeding-related complications after elective hepatic surgery.
