Background: Surgical technique using small-diameter  instruments and single-incision laparoscopy are two new options for less invasive laparoscopic cholecystectomy (LC). In this study, we have compared mini-LC (MLC) with single-incision LC (SILC). Materials and Methods: This study is a randomized clinical trial conducted on the patients diagnosed with  symptomatic cholelithiasis who underwent LC. Forty patients  were randomized to two equal groups of MLC and SILC. They  were compared in terms of demographic data, operation time, and surgical complications. Results: Baseline characteristics were similar in two groups. Operation time in MLC was significantly  shorter than that in SILC (45.1 ± 69 min vs 63.75 ± 7.57 min, P-value < 0.001). Also, the total length of the wound in SILC  group was shorter than that in MLC group (P-value < 0.003). Postoperative pain scores were similar in two groups.Hospital stay was shorter in MLC (1.2 ± 0.6 days vs 1.6 ± 0.8 days, P < 0.021). There was no difference in postoperative complications in two groups. Conclusion: MLC because of less operation time is preferred than SILC. Also, by subjective measures, it was a  more comfortable method compared to SILC.
