EXTERNAL PRINGLE MANEUVER IN LAPAROSCOPIC LIVER RESECTION: A SAFE, CHEAP AND REPRODUCIBLE WAY TO PERFORM IT.

backgroundTourniquet for right hepatectomy tightened and secured with forceps (arrow). Laparoscopic liver resection is performed worldwide. Hemorrhage is a major complication and bleeding control during hepatotomy is an important concern. Pringle maneuver remains the standard inflow occlusion technique.

aimDescribe an extracorporeal, efficient, fast, cheap and reproducible way to execute the Pringle maneuver in laparoscopic surgery, using a chest tube.

methodsFrom January 2014 to March 2020, our team performed 398 hepatectomies, 63 by laparoscopy. We systematically encircle the hepatoduodenal ligament and prepare a tourniquet to perform Pringle maneuver. In laparoscopy, we use a 24 Fr chest tube, which is inserted in the abdominal cavity through a small incision. We thread the cotton tape through the tube, pulling it out through the external end, outside the abdomen. To perform the tourniquet, we just need to push the tube as we hold the tape, clamping both with one forceps.

resultsThe 24 Fr chest tube is firm and works perfectly to occlude blood inflow as the cotton band is tightened. It has an internal diameter of 5,5 mm, sufficient for a laparoscopic grasper pass through it to catch the cotton band, and an external diameter of 8 mm, which allows to be inserted in the abdomen through a tiny incision. The cost of this tube and the cotton band is less than US$ 1. No complications related to the method were identified in our patients.

conclusionsThe extracorporeal Pringle maneuver presented here is a safe, cheap and reproducible method, that can be used for bleeding control in laparoscopic liver surgery.
