The learning curve with single-port cholecystectomy. [Journal Article]
JSLS 2009 Jul-Sep; 13(3):332-6.
OBJECTIVES: Single-port surgery is a rapidly advancing technique in laparoscopic surgery. Currently, there is limited evidence on the learning curve and practicality of performing single-port laparoscopic cholecystectomy.
METHODS: Single-port cholecystectomy was performed on 20 consecutive patients for biliary dyskinesia, symptomatic cholelithiasis, or acute cholecystitis. The Tri-Port was placed in the umbilicus, and a combination of straight and articulating instruments were utilized. Patient characteristics and outcomes were reviewed, and a comparison was made with the prior 20 consecutive laparoscopic cholecystectomies performed using the 3-port technique.
RESULTS: Characteristics were similar in both groups. The 3-port cholecystectomy had a mean time of 65.7 minutes, and patients had an average body mass index of 28.16. The first single-port cholecystectomy took 160 minutes with sequential improvement to the sixth case of 66 minutes with a mean of 68.2 minutes for the last 15 single-port cases. The average patient body mass index was 30.24. No major complications occurred.
CONCLUSION: The largest series to date of single-port cholecystectomy for multiple degrees of biliary disease is presented. This study validates that this technique can be applied effectively and performed in comparable operative times to traditional 3-port cholecystectomy with a learning curve of approximately 5 cases.
