The aim of this research project is to compare electrocautery to scalpel for laparotomy skin incisions, with the following objectives:

  1. To investigate whether electrocautery produces a cosmetically inferior surgical scar.
  2. To compare the rates of wound infection with each technique.
  3. To determine if electrocautery results in less postoperative pain. Our null hypothesis is that electrocautery is equivalent to scalpel for creating skin incisions; with respect to wound cosmesis, wound infection rate, and post-operative pain.

Further study details as provided by St. Paul's Hospital, Canada:

Primary Outcome Measures:
  • Scar Cosmesis [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]
    At 6 months post-operative, patients' scars will be evaluated by two independent trained blinded observers who will use the Patient Observer Scar Assessment Scale (POSAS) and the Vancouver Scar Scale (VSS) to evaluate the cosmesis of the surgical scar. Patients, who are blinded to the type of incision they have received, will also subjectively assign a score to their scar using the POSAS.

Secondary Outcome Measures:
  • Wound Infection Rate [ Time Frame: within 6 months post-operatively ] [ Designated as safety issue: Yes ]
    Superficial incisional surgical site infection as defined by the Centres for Disease Control (CDC).

  • Post-operative wound pain [ Time Frame: within 5 days post-operatively ] [ Designated as safety issue: Yes ]
    Patients will also be asked to record their daily post-operative incision pain using the visual analogue score (VAS) until post-operative day 5.
