Single-Incision Laparoscopic Cholecystectomy Using a Set of Novel Needle Instruments.

Background: Although the technique of single-incision laparoscopic cholecystectomy (SILC) has improved remarkably, problems such as limited exposure and instrument collision persist. We describe a new SILC technique that uses a set of specially-designed needle instruments.

Methods: Fifty-six patients with benign gallbladder disease underwent SILC using the newly-designed needle assembly instruments (NAIs).

Laparoscopic Versus Open Appendectomy for Acute Appendicitis in Children.

Objective: To compare the efficacy and safety of laparoscopic appendectomy and open appendectomy for acute appendicitis in children.

Methods: This study was conducted as a retrospective comparison of hospital records for postoperative complications, duration of operation, and postoperative length of stay between children (aged <18y) who underwent laparoscopic (n=190) or open (n=199) appendectomy over a six-year period. Quality of life was evaluated immediately and 1 month postoperatively.
