Does thromboprophylaxis cause bleeding after laparoscopic cholecystectomy?

Area of Science:

• General Surgery
• Thrombosis Research

Background:

• Venous thromboembolism (VTE) prevention is critical in surgery, yet its necessity in laparoscopic cholecystectomy remains debated.
• Risk stratification for VTE in this patient population is essential for appropriate prophylaxis.

Purpose of the Study:

• To evaluate the safety and efficacy of selective pharmacological VTE prophylaxis in patients undergoing laparoscopic cholecystectomy.
• To analyze the incidence of VTE and bleeding complications in relation to thromboprophylaxis use.

Main Methods:

• Retrospective analysis of 1485 patients undergoing laparoscopic cholecystectomy between 2005 and 2015.
• Patients were stratified by VTE risk, with prophylaxis administered selectively.
• Fisher Exact Test used to compare outcomes between prophylaxis and no-prophylaxis groups.

Main Results:

• 1178 patients (79.33%) received VTE prophylaxis, while 307 (20.67%) with low risk did not.
• Bleeding complications occurred in 1.18% of prophylaxis patients and 0.65% of non-prophylaxis patients (p=0.548).
• No clinically symptomatic VTE events were observed in the study cohort.

Conclusions:

• Selective VTE prophylaxis in laparoscopic cholecystectomy does not significantly increase bleeding risk.
• This strategy is likely effective in decreasing symptomatic thrombotic complications.
