A randomized phase II study of the clinical effects of ultrasonically activated coagulating shears (Harmonic scalpel) in open gastrectomy for gastric cancer. Surg Today 2016; 46: 561–568.

Published: 9th November 2016

Authors: Kawabata R, Takiguchi S, Kimura Y, Imamura H, Fujita J, Tamura S et al.

Conclusion

Some 248 procedures were studied. Use of harmonic scalpel did not affect the duration of surgery (141 min versus 147 min in controls) or blood loss (365 versus 336ml respectively).
