A prospective randomised trial of LigaSure Small Jaw® versus conventional neck dissection in head and neck cancer patients

Abstract

Objectives: We compared the differences between LigaSure Small Jaw®-assisted and conventional neck dissection in patients with head and neck cancer.

Design: Prospective randomised study.

Setting: Tertiary referral hospital.

Participants: Patients scheduled to undergo neck dissection due to head and neck cancer were eligible for this study. The study group was treated using the LigaSure vessel sealing system (Small Jaw®; Covidien, Colorado, USA) for dissection and hemostasis throughout the whole procedures (ClinicalTrials.gov number: NCT02597582).

Main outcomes measures: Operation duration, perioperative blood loss, postoperative drainage amount and postoperative pain status.

Results: The study group consisted of 21 patients, while the control group had 20 patients. The operation duration was shorter (97.1 versus 116.3 min, P = 0.022) and the average amount of injected analgesics was lower (8.8 versus 17.7 ampules, P = 0.037) in the study group.

Conclusions: The assistance of the LigaSure Small Jaw® during functional neck dissection shortened the operation duration and decreased the amount of injected analgesics needed.
