The goal of this study is to investigate the feasibility, safety and effectiveness of this LOFF device on patients undergoing cholecystectomy.<\/jats:p>\n <\/jats:sec>\n \n Methods:<\/jats:title>\n Patients with cholecystolithiasis or gallbladder polyps who underwent single port cholecystectomy from June 2015 to May 2016 were retrospectively reviewed. Either the LOFF-assisted laparoendoscopic single-port surgery (LESS) (LOFF-LESS) or the traditional LESS was performed. Operation time, intraoperative bleeding, postoperative hospital stay, surgical complications, incision pain score, shoulder and back pain and cosmetic satisfaction were compared.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n A total of 186 patients were included in this study, with 79 in the LOFF-LESS group and 107 in the LESS group. There was no significant difference between LOFF-LESS group and LESS group in operation field establishment time, cholecystectomy time, intraoperative bleeding, postoperative hospital stay, incision pain and cosmetic satisfaction. A lower intraoperative arterial carbon dioxide pressure was documented in the LOFF-LESS group (P<\/jats:italic><0.01). The incidence of postoperative shoulder and back pain was significantly lower in LOFF-LESS group (P<\/jats:italic><0.01).<\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n LOFF-LESS has comparable benefits of traditional LESS; it deceases incidence of pneumoperitoneum related complications as well.<\/jats:p>\n
