title: A prospective randomised trial of LigaSure Small Jaw® versus conventional neck dissection in head and neck cancer patients.
abstract: OBJECTIVE
  We compared the differences between LigaSure Small Jaw®-assisted and conventional neck dissection in patients with head and neck cancer.
  
  
  METHODS
  Prospective randomised study.
  
  
  METHODS
  Tertiary referral hospital.
  
  
  METHODS
  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).
  
  
  METHODS
  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.
