The harmonic scalpel: an intraoperative complication

J T Awwad et al. Obstet Gynecol. 1996 Oct.

Abstract

Background: The harmonic scalpel is an ultrasonically activated surgical instrument for tissue dissection. Despite its expanding surgical applications, there are no reports about associated complications.

Case: A 35-year-old woman sustained injury to the sigmoid colon from the use of the harmonic scalpel during laparoscopic lysis of pelvic adhesions. The injury was identified and repaired laparoscopically in a primary fashion with no subsequent sequelae.

Conclusion: Acoustic energy coupling and overheating of the laparosonic blade extender sheath occur with bending of the instrument. This can happen with steering of the blade extender during laparoscopic surgery and may increase the exposure risk of adjacent tissues to injury.
