Abstract

Background: The conventional 3-4 port laparoscopic cholecystectomy is the standard surgery. The single
incision laparoscopic cholecystectomy had been developed to reduce pain for a better recovery and improve
cosmesis of surgical wounds. However, previous study showed mixed results leading to ambiguous conclusion.
Objectives: To study and compare the effectiveness of short-term single incision laparoscopic cholecystectomy
versus conventional 3-port laparoscopic cholecystectomy
Materials and Methods: One hundred and ninety eight patients, who had laparoscopic cholecystectomy from
January 2012 to December 2014, were randomized to the single incision laparoscopic cholecystectomy (SILC) and
the conventional 3-port laparoscopic cholecystectomy (CLC). The operative time, postoperative complication,
postoperative pain, length of hospital stay, time to resume to work, and cosmesis outcome were compared between
two groups.
Results: One hundred and ninety eight patients were divided into 99 patients each group. After processing,
there were 92 patients in the SILC group and 94 patients in the CLC. Patients’ characteristics including gender, age,
body mass index, and ASA conditions showed no significant difference. Mean operative time for SILC was
significantly longer than that of CLC (35 minutes vs. 30 minutes; p < 0.01). The length of hospital stay for both groups
was similar (3 days; p > 0.01). The time back to work for SILC patients was 14 days and 10 days for the CLC which
was not significantly different (p > 0.01). There was no postoperative complication in both groups. The mean of
postoperative pain level after the surgery in the first 24 hours in SILC was significantly higher than CLC (2.53 ± 1.51,
1.79 ± 0.98 respectively; p < 0.01). The cosmesis outcome of SILC was greater than CLC (23.19 ± 1.31 vs.
22.42 ± 1.45; p < 0.01).
Conclusion: The SILC had the same length of hospital stay and time to resume to work as the CLC, but took
more operative time with more postoperative pain within the first 24 hours. However, the cosmesis outcome of the
SILC was better than the CLC.
