Can a Fully Articulating Electromechanical Laparoscopic Needle Driver Compare with a Robotic Platform in Transabdominal Preperitoneal Inguinal Hernia Repair?

Enhanced laparoscopic instruments are filling the gap between straight-stick laparoscopic equipment and robotic platforms. We sought to evaluate the performance and cost of the HandX™ device during mesh fixation and peritoneal flap closure of transabdominal preperitoneal (TAPP) inguinal hernia repairs. The video recordings of a consecutive series of TAPP surgeries using the articulated needle driver device were compared with a series of surgeries on the DaVinci robotic platform by a single surgeon. Two critical steps of the procedure were analyzed: mesh fixation and peritoneal closure. A cost analysis between the two platforms was completed. We analyzed 27 cases using the new needle driver and 27 cases using the DaVinci Surgical Robotic system. To evaluate the learning curve (LC) with the HandX device, we created three groups (G1, G2, and G3). The two latter groups were combined and called after LC. Mean fixation time using the DaVinci system was 258.1 seconds (±100.4) compared with 391.5 (±95.9) using the articulating handheld laparoscopic needle driver after LC ( < .001). The average time for peritoneal closure was 418.6 (±192.1) seconds for DaVinci and 634.5 (±159.5) seconds for HandX ( < .001). When comparing the after-LC HandX cases and the DaVinci system stratified by side, there was no significant difference in peritoneal closure in the right side (520.1 seconds (84.3) with the HandX versus 444.2 seconds (229.7) using the DaVinci system ( = .353). When evaluating direct cost of the instruments, HandX cases had a lower cost (310 USD) when compared with the cost of using DaVinci (973 USD). The new smart articulating needle driver may be a cost-effective means of bringing some of the benefits of the robotic platform to laparoscopy.
