Comparison of Outcome of Monopolar Diathermy Versus Harmonic Scalpel in Terms of Gallbladder Perforation in Laparoscopic Cholecystectomy
Background : To compare the outcome (in terms
of gall bladder perforation) of monopolar diathermy
versus harmonic scalpel use during laparoscopic
Cholecystectomy (LC) .
Methods: In this randomized controlled trial 170
patients of both gender between age 20 to 60 years
planned for undergoing laparoscopic
cholecystectomy for symptomatic gallstones, were
included. Patients were randomly allocated to Group
A (harmonic scalpel) and Group B (monopolar
diathermy). Outcome was measured in terms of gall
bladder perforation during the procedure in both
Results: Satisfactory outcome (non-perforated
gallbladder) was significantly higher in patients
who underwent LC with harmonic scalpel (90.6%,
n=77/85) when compared to patients underwent LC
with monopolar diathermy (77.6%, n=66/85). P-value
found to be 0.021.
Conclusion: Use of harmonic scalpel is found to be
a better a choice during laparoscopic
cholecystectomy in terms of per operative
gallbladder perforation as compared to monopolar
