Abstract

Purpose:Few authors have studied applying the laparoscopic approach in patients with previous upper abdominal operations, but no comparison has been made between laparoscopic and open approaches in patients with previous upper abdominal operations. This article aims to introduce surgical techniques and details in treatment to surgeons specialized in minimally invasive surgery.Materials and Methods:From January 2010 to January 2018, 460 eligible patients were divided into 3 groups and analyzed retrospectively. Group A: patients with a history of upper abdominal operations who underwent laparoscopy (n=124); group B: patients without a history of upper abdominal operations who underwent laparoscopy (n=140); and group C: patients with a history of upper abdominal operations who underwent an open operation (n=196). Group A was the experimental group; groups B and C served as the control groups.Results:No significant difference was found between groups A and B. Significant differences were found between groups A and C in estimated blood loss (258.3±67.2 vs. 424.7±103.7 mL, P<0.001), postoperative hospitalization (5.7±2.3 vs. 10.2±3.1 d, P<0.001), and postoperative complications (16.1% vs. 42.9%, P=0.013). The final rate of stones clearance was 100% in 3 groups. The total rate of stone recurrence was 7.8%.Conclusions:Laparoscopy with certain surgical techniques was feasible, effective, and advantageous for patients with previous upper abdominal operations by experienced surgeons. It is necessary for surgeons to have advanced skills and surgical techniques to achieve a successful laparoscopy.
