Single-incision laparoscopic cholecystectomy with inflexible laparoscopic instruments and laparoscopy: a single-center experience of 533 cases.

Single-incision laparoscopic cholecystectomy (SILC) was considered as an option for minimizing surgical injuries and improving outcomes. However, the benefit of this novel technique, especially with conventional and inflexible instruments and laparoscopy, is still controversial.
