Staple Line Reinforcement for Intracorporeal Anastomosis Reduces Time for Reconstruction During Laparoscopic Gastrectomy for Gastric Cancer

Background/Aim: Despite the widespread use of laparoscopic surgery, intracorporeal anastomosis remains a complicated procedure that often prolongs the operation time. This study aimed to investigate the efficacy of a novel staple line reinforcement (SLR) during laparoscopic gastrectomy for gastric cancer. Patients and Methods: The study included 30 patients who underwent laparoscopic gastrectomy for gastric cancer at the Kochi Medical School between November 2021 and May 2022. A review of these patients was conducted, and perioperative outcomes were compared according to the use of SLR. Results: The reconstruction time using SLR was significantly shorter compared to when SLR was not used (20.5 min vs. 32.0 min, p=0.048). The incidence of hemostasis during anastomosis was significantly lower in the SLR group than in the non-SLR group (0 vs. 3 times, p=0.041). There were no significant differences in the operating time and estimated blood loss after surgery between the two groups. Furthermore, there were no significant differences in postoperative complications or nutritional status between the two groups. Conclusion: The usefulness of SLR in reducing the time for intracorporeal reconstruction and archiving the best interaction between device and tissue during laparoscopic gastrectomy for gastric cancer, was herein demonstrated.
