BACKGROUND
Magnetic anchor technique (MAT) has been applied in laparoscopic cholecystectomy and laparoscopic appendectomy, but has not been reported in laparoscopic partial hepatectomy.
AIM
To evaluate the feasibility of the MAT in laparoscopic left lateral segment liver resection.
METHODS
Retrospective analysis was conducted on the clinical data of eight patients who underwent laparoscopic left lateral segment liver resection assisted by MAT in our department from July 2020 to November 2021. The Y-Z magnetic anchor devices (Y-Z MADs) was independently designed and developed by the author of this paper, which consists of the anchor magnet and magnetic grasping apparatus. Surgical time, intraoperative blood loss, intraoperative accidents, operator experience, postoperative incision pain score, postoperative complications, and other indicators were evaluated and analyzed.
RESULTS
All eight patients underwent a MAT-assisted laparoscopic left lateral segment liver resection, including three patients undertaking conventional 5-port and five patients having a transumbilical single-port operation. The mean operation time was 138 ± 34.32 min (range 95-185 min) and the mean intraoperative blood loss was 123 ± 88.60 mL (range 20-300 mL). No adverse events occurred during the operation. The Y-Z MADs showed good workability and maneuverability in both tissue and organ exposure. In particular, the operators did not experience either a “chopstick” or “sword-fight” effect in the single-port laparoscopic operation.
CONCLUSION
The results show that the MAT is safe and feasible for laparoscopic left lateral segment liver resection, especially, exhibits its unique abettance for transumbilical single-port laparoscopic left lateral segment liver resection.
Core Tip: Magnetic anchor technique (MAT) can be used to assist in exposing tissues or organs during laparoscopic surgery, thereby effectively reducing the number of trocars and eliminating interference between laparoscopic instruments. This study retrospectively analyzed eight patients who underwent laparoscopic left lateral lobectomy using Y-Z magnetic anchor devices. The results showed that MAT is safe and feasible for transumbilical single-port laparoscopic left lateral hepatectomy.
