Summary
Laparoscopic inguinal hernia repair using the intraperitoneal approach significantly reduces femoral venous flow, increasing deep vein thrombosis risk. The preperitoneal approach does not affect venous flow, suggesting it may be safer.
Area of Science:
- Vascular Surgery
- Minimally Invasive Surgery
- Thromboembolic Complications
Background:
- Laparoscopic inguinal hernia repair can be performed via intraperitoneal or preperitoneal routes.
- Intraperitoneal insufflation may increase deep vein thrombosis (DVT) risk due to altered lower extremity venous flow.
- Direct comparison of femoral venous flow between these approaches is lacking.
Purpose of the Study:
- To compare common femoral vein blood flow during intraperitoneal versus preperitoneal insufflation in laparoscopic inguinal hernia repair.
- To assess the impact of each laparoscopic approach on venous flow dynamics.
Main Methods:
- Eight male patients undergoing laparoscopic herniorrhaphy were studied under general anesthesia.
- Common femoral vein flow was measured using duplex ultrasound.
- Venous flow was assessed at baseline, during standardized intraperitoneal (10 mm Hg) and preperitoneal (10 mm Hg) insufflation, and during inter-insufflation periods.
Main Results:
- Mean common femoral vein flow was 138 ml/min at baseline and 135 ml/min during preperitoneal insufflation.
- Mean femoral vein flow significantly decreased to 65 ml/min during intraperitoneal insufflation (p = 0.02).
- No significant change in venous flow was observed with the preperitoneal approach.
Conclusions:
- Intraperitoneal insufflation significantly reduces common femoral vein blood flow.
- Preperitoneal insufflation does not impact common femoral vein blood flow.
- Laparoscopic preperitoneal inguinal hernia repair may offer a lower risk of thromboembolic complications compared to the intraperitoneal approach.
