Venous thrombosis following laparoscopic cholecystectomy: Analysis of 12 cases / 中国微创外科杂志

ABSTRACT

Objective To investigate the etiology and prevention of venous thrombosis (VT) following laparoscopic cholecystectomy (LC). Methods A retrospective analysis on clinical records of 12 cases of VT following 258 cases of LC in this hospital from January 2002 to June 2004 was carried out. Results [WTBZ]The operation time was 17~58 min (mean, 38 min), and the intraoperative blood loss was 15~100 ml (mean, 45 ml). In 11 cases of superficial vein thrombosis, on a treatment for 6~8 days the symptoms of redness, swelling, heat, and pain vanished. Re-examinations of color Doppler ultrasonography revealed disappearance of thrombosis, and an anticoagulation therapy with Warfarin was given. Follow-ups for 6~12 months found no recurrence. In 1 case of deep femoral vein thrombosis accompanying pulmonary embolism, an anticoagulation therapy was employed for 4 months and a follow-up for 6 months showed no recurrence. Conclusions The development of VT following LC is correlated to patients' high-risk factors, carbon dioxide pneumoperitoneum, and anesthesia administration. Emphasis should be on active countermeasures during peri-operative period.
