IntroductionAlthough laparoscopic cholecystectomy appears to be less traumatic to the patients than open surgery, decreased venous return from lower extremities and hypercoagulability occurring in patients undergoing elective laparoscopic cholecystectomy with CO2 pneumoperitoneum makes it a potent risk factor for deep venous thrombosis.MethodsThe observational study of 50 patients undergoing elective laparoscopic cholecystectomy was designed to study alteration in PT, APTT, d-dimer and antithrombin III, which were measured preoperatively, 6 and 24 h postoperatively. It was accompanied by color duplex ultrasound of bilateral lower limbs preoperatively and 7th day postoperatively to look for evidence of deep venous thrombosis.ResultsSignificant postoperative decrease in APTT and antithrombin III suggested activation of coagulation while decrease in d-dimer suggested activation of fibrinolysis. Values of PT had no statistically significant postoperative changes. Age, body mass index and duration of pneumoperitoneum were found to correlate with significant activation of coagulation and fibrinolysis. None of the patients developed clinical or radiological evidence of deep venous thrombosis in the postoperative period.ConclusionsCO2 pneumoperitoneum enhances the activation of coagulation and fibrinolysis associated with laparoscopic cholecystectomy. Patients with risk factors like old age, obesity or with expected long duration of laparoscopic surgery are likely to have significant activation of coagulation, making them a vulnerable risk group for development of postoperative deep vein thrombosis, warranting some form of thromboprophylaxis.
