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/m(2)) 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 5 years.
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 +/- 10.9 years; mean baseline BMI, 41.4 +/- 5.5 (81.6% women); 58 patients (27.4%) had type 2 diabetes.
Mean operative time was 69.0 min; mean hospitalization, 38 h (24-72). ANOVA indicated a significant BMI reduction out to 2 years (p < 0.001), a plateau at 3 and 4 years, and a moderate but significant BMI increase at 5 years (p < 0.01).
EBMIL at 1, 2, 3, 4, and 5 years 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 5 years, 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.
