Background: Laparoscopic cholecystectomy is a minimally invasive procedure whereby the gallbladder is removed using laparoscopic techniques. Monopolar electerosurgical energy is the method of dissection of gallbladder from liver bed. Ultrasonic energy causes less thermal damage and suggests an alternative to monopolar elevterocautery. Leptin is a tissue factor and C-reactive protein (CRP) is an acute phase protein that builds up in surgical damages. In laparoscopy, pneumoperitoneum and thermal damage cause this increase. In this study, after completion of surgery with both methods, plasma leptin and CPR were measured. Next, the complications and benefits of the two methods were compared.

Methods: This single blind randomized clinical trial was conducted on 78 patients who were candidate for laparoscopic cholecystectomy in surgery clinic of Razi Teaching Hospital in Ahvaz Jundishapur University of Medical Sciences from March 2013 to March 2015. Patients were divided randomly into two groups of ultrasonic and electerocautery. Then, leptin’s level and CRP’s level were measured at completion of surgery, 30 minutes after completion, 6 and 24 hours after completion of surgery in the two groups.

Results: This study shows that the average rate of leptin at completion of surgery, 30 minutes after completion, 6 and 24 hours after completion of surgery in ultrasonic group had less increase than electerocautery group and the difference was statistically significant (P= 0.0001). The average rate of CRP at completion of surgery, 30 minutes after completion, 6 and 24 hours after completion of surgery in ultrasonic group had less increase than electerocautery group and the difference was statistically significant (P= 0.0001).

Conclusion: The level of leptin and CRP shows that surgery with ultrasonic method will provoke the immune system less than electerocautery method.
