Background: Information on the incidence of venous thromboembolism (VTE) following laparoscopic procedures is inadequate and there is currently no solid evidence to guide the use of thromboprophylaxis in this setting. Gynecologic laparoscopy is a common procedure, and is frequently performed in low-risk patients. To our knowledge, there are no clinical studies specifically designed to assess the incidence of VTE in this setting. Methods: In a prospective cohort study, consecutive patients undergoing gynecologic laparoscopy underwent compression ultrasonography (CUS) and clinical assessment to evaluate the incidence of clinically relevant VTE. CUS was performed 7 +/- 1 and 14 +/- 1 days postoperatively. A subsequent telephone contact was scheduled at 30 and 90 days. No patient received pharmacologic or mechanical prophylaxis. Patients with malignancy or previous VTE were excluded from the study. Results: We enrolled 266 consecutive patients; mean age was 36.3 years, range: 18-72. The most common indications for laparoscopy were ovarian cysts in 25.6% of patients, endometriosis in 21.0% of patients, unexplained adnexal masses in 12.4% of patients, and infertility in 7.5% of patients. The mean duration of the procedure was 60.5 min (range: 10-300 min). In particular, in 55.6% of patients the duration exceeded 45 min. There were neither episodes of CUS detected DVT (0/247; 0%, 95% CI 0-1.51%) or clinically relevant VTE after follow-up (0/256; 0%, 95% CI 0-1.48%). No patient died of fatal pulmonary embolism (0/266; 0%, 95% CI 0-1.42%). Conclusions: Gynecologic laparoscopy in non-cancer patients is a low-risk procedure for postoperative VTE.

Abstract
Background: Information on the incidence of venous thromboembolism (VTE) following laparoscopic procedures is inadequate and there is currently no solid evidence to guide the use of thromboprophylaxis in this setting. Gynecologic laparoscopy is a common procedure, and is frequently performed in low-risk patients. To our knowledge, there are no clinical studies specifically designed to assess the incidence of VTE in this setting. Methods: In a prospective cohort study, consecutive patients undergoing gynecologic laparoscopy underwent compression ultrasonography (CUS) and clinical assessment to evaluate the incidence of clinically relevant VTE. CUS was performed 7 +/- 1 and 14 +/- 1 days postoperatively. A subsequent telephone contact was scheduled at 30 and 90 days. No patient received pharmacologic or mechanical prophylaxis. Patients with malignancy or previous VTE were excluded from the study. Results: We enrolled 266 consecutive patients; mean age was 36.3 years, range: 18-72. The most common indications for laparoscopy were ovarian cysts in 25.6% of patients, endometriosis in 21.0% of patients, unexplained adnexal masses in 12.4% of patients, and infertility in 7.5% of patients. The mean duration of the procedure was 60.5 min (range: 10-300 min). In particular, in 55.6% of patients the duration exceeded 45 min. There were neither episodes of CUS detected DVT (0/247; 0%, 95% CI 0-1.51%) or clinically relevant VTE after follow-up (0/256; 0%, 95% CI 0-1.48%). No patient died of fatal pulmonary embolism (0/266; 0%, 95% CI 0-1.42%). Conclusions: Gynecologic laparoscopy in non-cancer patients is a low-risk procedure for postoperative VTE.
