Laparoscopic cholecystectomy does not increase thrombosis risk. Increased fibrinolytic activity may reduce thromboembolic risk by promoting hypocoagulability during and after surgery.

Area of Science:

  • Surgical Innovation
  • Hemostasis Research
  • Thrombosis Prevention

Background:

  • Assessing hemostasis changes in laparoscopic cholecystectomy to identify potential thrombosis risks.
  • Investigating the hemostatic profile of patients undergoing minimally invasive gallbladder surgery.

Purpose of the Study:

  • To evaluate hemostasis alterations during laparoscopic cholecystectomy.
  • To determine if these alterations correlate with an increased risk of thrombosis.

Main Methods:

  • Studied 20 patients undergoing laparoscopic cholecystectomy and 12 controls (herniorrhaphy).
  • Monitored hemostatic parameters including prothrombin activity (PA), APTT, fibrinogen, ATIII, PFA, EFA, and D-dimer at multiple time points.
  • Collected samples pre-operatively, intra-operatively, and post-operatively up to 7 days.

Main Results:

  • No thromboembolic events observed in either group during follow-up.
  • Laparoscopic cholecystectomy showed increased plasma fibrinolytic activity (PFA, EFA) and D-dimer levels post-surgery.
  • Hemostatic parameters remained within normal ranges, with no significant differences between groups.

Conclusions:

  • Laparoscopic cholecystectomy does not elevate plasma coagulation activation compared to low-risk surgery.
  • Increased fibrinolytic activity suggests a potential hypocoagulable state, possibly reducing thromboembolic risk post-surgery.
