Abstract

Background:

A recent meta-analysis and systematic review suggested that single-incision laparoscopic cholecystectomy (SILC) had a higher procedure failure rate with more blood loss and that it required a longer surgical time than conventional laparoscopic cholecystectomy. Herein, we introduce our experience with the needlescopic grasper-assisted and bendable retractor-assisted SILC technique and evaluate its safety and sustainability.

Methods:

The present retrospective cohort study included 407 Japanese patients who underwent needlescopic grasper-assisted and bendable retractor-assisted SILC between January 2012 and April 2017 at our institution.

Results:

In the present study, all patients successfully underwent needlescopic grasper-assisted and bendable retractor-assisted SILC without conversion to open surgery. Regarding surgical outcomes, mean surgical time was 58.2±23.2 minutes, and additional ports were required in 9 patients (2.2%). Postoperative morbidity developed in only 6 patients (1.4%).

Conclusions:

The surgical approaches defined herein were safe and sustainable with favorable surgical outcomes. Compared with conventional SILC, needlescopic grasper-assisted and bendable retractor-assisted SILC might become a mainstream procedure for minimally invasive surgery from the viewpoint of surgical difficulty.
