In recent years SILS has had a remarkable growth and represents a safe and an aesthetic surgical option for patients with some abdominal illness. Surgeons in developing countries have not adopted these technique due to the lack of specialized equipment and the high cost of articulated instruments.


The aim of these study was to explore the feasibility and safety of performing single incision laparoscopic surgery (SILS) with conventional laparoscopic instruments.


Retrospective analysis of 50 patients who underwent the above abdominal surgeries. Appendectomy (N=29), cholecystectomy (N=29), resection of ovarian cyst (N=2), partial omentectomy (N=1), aspiration of hemoperitoneum (N=1).


There was a rate of conversion to conventional laparoscopic surgery of 8% (N=4), none of them where converted to open surgery. Of the 8% (N=4) of the patients in witch conversion was made, accessory ports were used.
The mean surgical time was 36.5 minutes (15-120 min). The average age of patients was 36 years (10-70 years). The average BMI of patients was 24.38 (19-33 km/m2). 44% (N=22) were male and 56% (N=28) female. Average hospital stay 1.8 days (1-6 days)


Single port surgery is a safe option with better aesthetic results. With ergonomic and geometric principles used by our group conventional laparoscopic instruments is a safe and reproducible technique.
