Laparoendoscopic single-site surgery (LESS) was motivated by the desire to make minimally invasive surgery even more minimal. We performed gasless laparoendoscopic single-site surgery (GLESS) with abdominal wall lift (AWL) for cholecystectomy and fenestration of liver cyst. This study aims to assess the safety and feasibility of the techniques. From June to December 2009, 18 cases of gasless laparoendoscopic single-site cholecystectomy (GLESC) and 4 cases of fenestration of liver cyst (GLESF) were performed in Qilu Hospital of Shandong University, Shandong, China. Subcutaneous abdominal wall lifting system, LAP protector, flexible laparoscopes, and bent and articulating instruments were used during the procedures. Clinical data regarding patient demographics, operating time, blood loss, complications, and postoperative hospital stay were collected and analyzed retrospectively in the study. 17 cases of GLESC and 4 cases of GLESF were performed successfully, and 1 case of GLESC was converted to laparoendoscopic single-site cholecystectomy using AWL combined with low-pressure pneumoperitoneum. Mean body mass index was 23.7 +/- A 3.1 kg/m(2) for GLESC and 22.9 +/- A 1.5 kg/m(2) for GLESF. Mean operating time was 64 +/- A 17 min for GLESC and 101 +/- A 10 min for GLESF. Mean blood loss was 8 +/- A 3 ml for GLESC and 24 +/- A 11 ml for GLESF. Despite minor wound complication, no postoperative complications were observed during mean follow-up of 118 and 95 days for GLESC and GLESF, respectively. GLESS with AWL is safe and feasible for cholecystectomy and fenestration of liver cyst. The techniques provide satisfactory operative field exposure and an easier access method for LESS. Instrument collisions are greatly ameliorated both extra- and intracorporeally through use of flexible laparoscopes and bent and articulating instruments. This may prove to be a better approach for LESS techniques.
