Bottom Line: The ultrasonic Harmonic scalpel has demonstrated clinical and surgical benefits in dissection and coagulation.Compared with conventional hemostatic techniques, the Harmonic scalpel demonstrated significant reductions in operating time (-27.5 min; P < 0.001), intraoperative blood loss (-93.2 mL; P < 0.001), and drainage volume (-138.8 mL; P < 0.001).Results were numerically higher for conventional techniques for hospital length of stay, complication risk, and transfusions but did not reach statistical significance.

ABSTRACT
The ultrasonic Harmonic scalpel has demonstrated clinical and surgical benefits in dissection and coagulation. To evaluate its use in gastrectomy, we conducted a systematic review and meta-analysis of randomized controlled trials comparing the Harmonic scalpel to conventional techniques in gastrectomy for patients with gastric cancer. International databases were searched without language restrictions for comparisons in open or laparoscopic gastrectomy and lymphadenectomy. The meta-analysis used a random-effects model for all outcomes; continuous variables were analyzed for mean differences and dichotomous variables were analyzed for risk ratios. Sensitivity analyses were conducted for study quality, type of conventional technique, and imputation of study results. Ten studies (N = 935) met the inclusion criteria. Compared with conventional hemostatic techniques, the Harmonic scalpel demonstrated significant reductions in operating time (-27.5 min; P < 0.001), intraoperative blood loss (-93.2 mL; P < 0.001), and drainage volume (-138.8 mL; P < 0.001). Results were numerically higher for conventional techniques for hospital length of stay, complication risk, and transfusions but did not reach statistical significance. Results remained robust to sensitivity analyses. This meta-analysis demonstrates the clear advantages of using the Harmonic scalpel compared to conventional techniques, with improvements demonstrated across several outcome measures for patients undergoing gastrectomy and lymphadenectomy.

Mentions: Results demonstrated a lower risk of blood transfusions with the Harmonic scalpel than with conventional methods, although not statistically significant (RR of 0.68; 95% CI: 0.38 to 1.19; P = 0.18; 2 studies; I2 = 0%) (Figure 7). All results were reported for open gastrectomy.
