Background and Aims. We describe our experience of performing transumbilical single-incision laparoendoscopic cholecystectomy as standard procedure for acute and chronic gallbladder diseases. Methods. Between September 2008 and March 2010, 220 patients underwent laparoscopic single-incision surgery. A single port was used for 196 patients and two conventional 5 mm and one 10 mm port in 24 cases. All operations were performed with straight instruments. Results. Single-incision surgery was successfully performed in 215 patients (98%). Three patients (1.4%) required conversion to a three-port technique and two patients (0.9%) to an open procedure. Average age of 142 women (65%) and 78 men (35%) was 47 years (range: 15–89), average ASA status 2 (range: 1–3) and BMI 28 (range: 15–49). Mean operative time was 62 minutes (range: 26–174) and 57 patients (26%) had histopathological signs of acute cholecystitis. Eleven patients (5%) developed to surgery-related complications and nine (4%) of these required a reoperation. The mean followup was 331.5 (range: 11–590) days. Conclusion. Transumbilical single-incision cholecystectomy is a feasible and safe new approach for routine cholecystectomy. After a short learning curve, operation time and complication rate are comparable with standard multiport operation. In addition, most cases of acute cholecystitis can be performed with this technique.
