Comparison of Single Incision and Three Port Laparoscopic Cholecystectomy

ABSTRACT

PURPOSE: Laparoscopic surgery is a minimally invasive surgery which has been widely used in abdominal surgery, such as appendectomy and cholecystectomy. There were several strong points in single incision laparoscopic cholecystectomy (SILC). However, no definite study comparing SILC with three port laparoscopic cholecystectomy (TPLC) has been reported. Therefore, this study focused on feasibility and safety of SILC in comparison with conventional TPLC. METHODS: This study included 86 cases of SILC and 230 cases of TPLC from April, 2010 to February, 2011. The patients were divided into two groups according to the surgical procedure, group 1 was SILC and group 2 was TPLC. All operations were performed by a single surgeon, and the retrograde approach was the fundamental surgical procedure used in both groups. RESULTS: Eighty five patients in group 1 underwent SILC and 229 patients in group 2 underwent TPLC. In comparison of preoperative data, statistical significance regarding age, gender, and preoperative PTGBD insertion was observed between the two groups. In comparison of intraoperative data, the average operation time and average hospital day did not show any statistical significance. Intraoperative multiple port conversion was performed in group 1 to TPLC due to cystic artery bleeding, and in group 2, TPLC was changed into a four port operation due to the same reason. CONCLUSION: In this study, no significant difference in operation result, time, and acute complication was observed between SILC and conventional TPLC. Besides the cancers, SILC could definitely be applied without exclusion criteria mentioned above if improvement of instruments and accumulation of surgeon's experience were satisfied.
