Background: A new laparoscopic cholecystectomy technique uses a single umbilical port, to reduce trauma. Aim: To evaluate prospectively the feasibility of performing single incision laparoscopic cholecystectomies. Material and Methods: Patients with cholelithiasis or gallbladder polyps, without recent acute biliary episodes and a normal biliary tract were considered eligible for the study. An optical device with a working channel was introduced through a single umbilical incisión. A second smaller trocar was also introduced through the same incisión. Results: Between May 2008 and February 2009, twelve women aged 14 to 64 years (nine with cholelitiasis and three with gallbladder polyps) fulfilled inclusion criteria. The procedure lasted 160 minutes at the beginning of the series to 45 minutes in the latest cases. Abdominal pain and hospital stay (12-48 hours) do not differ from patients subjected conventional laparoscopy cases. No complication was recorded and no patient had to be converted to conventional surgery. Conclusions: Single umbilical incisión laparoscopic cholecystectomy is similar to conventional laparoscopy procedures in terms of surgical pain and hospital stay and offers a better esthetic outcome.
