Abstract
BACKGROUNDS/AIMS: This study was conducted to verify and compare the safety and feasibility of single incision laparoscopic cholecystectomy (SILC) and conventional laparoscopic cholecystectomy (CLC). METHODS: A total of 2,080 patients underwent laparoscopic cholecystectomy in a single center, Konyang University Hospital, between 2010 and 2016. We retrospectively compared the demographics, perioperative outcome, and postoperative complication results between the CLC and SILC groups. RESULTS: Among the 2,080 patients who underwent laparoscopic cholecystectomy, 1,080 had CLC and 1,000 had SILC. When retrospectively reviewed, the SILC group had significantly higher percentages of patients who were aged under 80 years, who were women, and had the American Society of Anesthesiologist score of lower than 3 points compared to those of the CLC group. Furthermore, the CLC group had a higher percentage of patients with acute cholecystitis or empyema, whereas the SILC group had a higher percentage of patients with chronic cholecystitis. Preoperative percutaneous transhepatic gallbladder drainage insertion or H-vac insertion was more frequently conducted, bleeding loss was more common, and hospital stay was longer in the CLC group. Postoperative complications such as wound infection, biloma, bile duct injury, and duodenal perforation were not significantly different between the two groups. CONCLUSIONS: In conclusion, if performed after preoperative patient selection such as in younger and female patients with no abdominal operation history at the time of benign gallbladder surgery, SILC can be considered feasible and safe without additional complications when compared with CLC.
