Laparoscopic Gastric Plication; Comparative Study between Modified Enteric Bypass and Loop Bipartition

Abstract

Background: Laparoscopic gastric plication (LGP) is emerging as a safe and effective bariatric procedure. A comparative study between the efficacy and complications of LGP with modified enteric bypass and LGP with loop bipartition, which are still an investigational bariatric procedure. The objective of this study to compare safety and efficacy of LGP with enteric bypass and LGP with loop bipartition in the treatment of morbid obesity in a one-year follow-up study. Methods: A prospective study between February 2016 to December 2017, conducted on 80 morbid obese patients who were candidates for laparoscopic gastric plication, with either loop bipartition or modified enteric bypass surgery were randomly assigned to receive either LGP modified enteric bypass (n = 40) or LGP with loop bipartition (n = 40). Early and late complications, body mass index (BMI), excess weight loss, and obesityrelated co-morbidities were determined at the 1-year follow-up. Results: Operative time and mean length of hospitalization were shorter in the LGP with modified enteric bypass group than LGP with loop bipartition; (110 minutes versus 120 minutes, P<.001, and 2 days versus 3 days; P<.001, respectively). The mean percentage of excess weight loss (%EWL) at 12 months follow-up was (79.5%) in the LGB with modified enteric bypass group and (74.1%) in the LGP group (P = 0.03). Improvement was observed in all co-morbidities in both groups. Conclusion: Both LGP and LGB are effective weight loss procedures. LGP enteric bypass proved to be a simpler and less costly procedure compared with LGP with loop bipartition with a lower risk of stomal ulcer during one year follow up.
