The authors describe a surgical technique which allows, without increasing costs, to perform laparoscopic cholecystectomy with a single incision, without using specific materials and with better surgical ergonomics. The technique consists of a longitudinal umbilical incision, navel detachment, use of a permanent 10mm trocar and two clamps directly and bilaterally through the aponeurosis without the use of 5mm trocars, transcutaneous gallbladder repair with straight needle cotton suture, ligation with unabsorbable suture and umbilical incision for the specimen extraction. The presented technique enables the procedure with conventional and permanent materials, improving surgical ergonomics, with safety and aesthetic advantages.

Introduction: Hilar cholangiocarcinomas, also known as Klatskin tumors are second most common malignancies of hepatobiliary malignancies and accounted for nearly 3% of all gastrointestinal malignancies. The aim of this study was present surgical outcomes in hilar cholangiocarcinoma at single center. Method: Between 2008 and 2014, 30 patients were treated in our clinic, only surgically resected and pathologically proved patients suffered for hilar cholangiocarcinoma were included the study. Surgical approaches and survival rates were analysed retrospectively. Results: 23 patient were male, 7 patients were female; middle age was 60,7 (43-75); accordingly Bismuth-Corlette Classification; 3 patients were Type I, 2 patients were Type II, 5 patients were Type IIIa, 17 patients were Type IIIb and 3 patients were Type IV. 5 patients underwent hepatectomy and portal vein resection, 20 patients underwent hepatectomy, 3 patients underwent Whipple procedure and external bile duct resection and 2 patients were treated only external bile duct resection. Our postoperative (90 day) mortality ratio was %16.6 (5 patients) and mean survival was 35.0 AE 6.2 months. 1-year and 5-year survival were 66.2% and 35.4%, respectively. Conclusions: Surgical resection is the recommended treatment option in resectable in hilar cholangiocarcinoma.
