Long-Term Outcomes of Laparoscopic Greater Curvature Plication and Laparoscopic Sleeve Gastrectomy: Critical Appraisal of the Role of Gastric Plication in Bariatric Surgery

Background and Objectives: This single-center study aimed to assess the role of laparoscopic greater curvature plication (LGCP) in bariatric surgery. Materials and Methods: Using data from our institution’s prospectively maintained database, we identified adult patients with obesity who underwent either laparoscopic sleeve gastrectomy (LSG) or LGCP between January 2012 and July 2017. In total, 280 patients were enrolled in this study. Results: The body mass index was higher in the LSG group than in the LGCP group (39.3 vs. 33.3, p < 0.001). Both groups achieved significant weight loss during the 3-year follow-up (p < 0.001). The weight-reduction rate was higher in the LSG group than in the LGCP group 6, 12, and 24 months postoperatively (p = 0.001, 0.001, and 0.012, respectively). The reoperation rate of the LGCP group was higher than that of the LSG group (p = 0.001). No deaths were recorded in either group. Conclusions: Although both the LGCP and LSG groups achieved significant weight loss over three years, the LGCP group demonstrated a lower weight-reduction rate and a higher reoperation rate than the LSG group. Thus, it is necessary to reassess the role of LGCP in bariatric surgery, particularly when LSG is a feasible alternative.
