Abstract
Laparoscopic greater curvature plication (LGCP) is a newer metabolic/bariatric surgical procedure that requires no resection, bypass, or implantable device. We report outcomes in a cohort of LGCP patients at 5-year follow-up. Body mass index (BMI, kg/m2) evolution, excess weight loss (%EWL), excess BMI loss (%EBMIL), and total weight loss (%TWL) were recorded. Repeated measures analysis of variance (ANOVA) was used to assess BMI change over 5years. Two-step cluster analysis was used to profile LGCP patients according to significant characteristics relative to successful 5-year weight loss. Of patients entering the study between 2010 and 2011 with complete weight data through 5-year follow-up (86.9%, 212/244), mean age was 45.8±10.9years; mean baseline BMI, 41.4±5.5 (81.6% women); 58 patients (27.4%) had type 2 diabetes. Mean operative time was 69.0min; mean hospitalization, 38h (24-72). ANOVA indicated a significant BMI reduction out to 2years (p<0.001), a plateau at 3 and 4years, and a moderate but significant BMI increase at 5years (p<0.01). EBMIL at 1, 2, 3, 4, and 5years was as follows: 50.7±9.1%, 61.5±8.1%, 60.2±7.0%, 58.5±7.0%, and 56.8±6.3%. At 5years, 79.2% (168/212) of patients were successful; 20.8% (44/212) experienced a suboptimal weight outcome; mean weight regain, 9.2%. Cluster analysis identified four distinct LGCP patient profiles. Diabetes improvement rate was 65.5%. There were 12 reoperations (4.9%): 4 emergency (1.6%) and 8 (3.3%) elective. There was no mortality. At 5-year follow-up, LGCP proved to be safe and effective, with 56.8% EBMIL and a low rate of complications.
