Comparative randomized controlled clinical trial of diathermy versus
scalpel incision in midline laparotomy
Bhavin P. Vadodariya*, Nimish J. Shah, Mrudul Patel
INTRODUCTION
Laparotomy skin incisions are made by scalpels with
disposable knives, these incisions are associated with
more blood loss and pain.

Surgical diathermy was
introduced at the beginning of the 20
th
century to
preclude the integral drawbacks of steel scalpel.

It is
well thought out to be competent mode of dissection
being hemostatic and suitable.

With the introduction of
recent electrosurgical units accomplished of distributing
pure sinusoidal current, this technique is now
exceptionally popular because of rapid haemostasis,
faster dissection and reduced overall operative blood
loss.

In diathermy, a potential gradient dependent current is
passed through the tissue at high frequency (greater than
100000Hz) to excite tissue molecules such as water
resulting in precise tissue lyses, which can be used for
employed to coagulate (modulated mode) or to cut
(sinusoidal mode) the tissue. This principle permits the
use of diathermy electrode without causing adjacent
ABSTRACT
Background: Laparotomy incisions have traditionally been made using a scalpel. Diathermy, a latest technique, is
thought to increase the risk of infection, impair healing and decrease cosmesis. Recent studies suggest that diathermy
may offer likely advantages with respect to blood loss, incision time and postoperative pain. The aim of this study
was to compare the efficacy and safety of surgical diathermy incisions versus conventional scalpel incisions for
midline laparotomy in our hospital with an aim to evaluate diathermy as an operational alternative to scalpel incision.
Methods: This was a prospective randomized clinical study which was conducted in the surgical wards of Medical
College & SSG hospital, Vadodara, between December 2013 and December 2014. Patients were randomly assigned
to two groups i.e. Group A (scalpel group) and Group B (diathermy group).
Results: A total of 148 patients were enrolled in the study. Of these, 74 patients were randomized to Group A (scalpel
group) and 74 patients to Group B (diathermy group). The two groups did not vary significantly in relation to age and
sex (p>0.001). Laparotomy skin incisions using diathermy were significantly quicker than scalpel incisions (p=0.624).
There was significantly less blood loss in the diathermy group compared with the scalpel group (P=0.15). The mean
visual analogue scale was significantly reduced more in the diathermy group than in scalpel group patients on
postoperative day 1 (p=0.81), day 3 (p=0.71) and day 5 (p=0.79) respectively. Postoperative complication rates did
not differ significantly between the scalpel and diathermy groups (p=0.624).
Conclusions: We concluded that diathermy incision in midline laparotomy has significant advantages compared with
the scalpel because of reduced incision time, less blood loss, reduced early postoperative pain and postoperative
wound infection.
