Background: Recent large-scale studies have concluded that laparoscopic sleeve gastrectomy (LSG) is superior to laparoscopic gastric greater curve plication (LGP) in weight loss outcomes and post-operative complications, but LGP is still being performed due to its purported financial advantage. Our analysis provides an investigation of cost at the time of operation, and a consideration of the financial implications of the complications and percentage of reoperation associated with each procedure.
Methods: A systematic literature search was performed on the electronic medical databases PubMed and Embase. Extraction of data was performed using a pre-made form which included number of subjects, minor complications and rates, major complications and rates, reoperation rate, percent end weight loss, length of operating time, and length of hospital stay.
Results: Twenty-eight records were included after screening for inclusion criteria, representing data from 3242 patients (2668 with LGP and 574 with LSG). Minor and major complications of LGP were documented in 28.7% and 7.2% of cases, respectively, and the rate of reoperation was 10.2%. Minor and major complications of LSG were 19.4% and 4.1%, respectively, and the rate of reoperation was 3.3%. Based on analysis of operating time and length of hospital stay means, each LGP operation was calculated to cost $10,730 USD, and LSG cost $14,074.
Conclusions: LGP has higher rates of complications and reoperation, and less %EWL compared with LSG. Despite modest initial cost benefit of LGP, when considering costs associated with the complications and reoperations, we conclude that LSG is superior to LGP in outcome and cost-effectiveness.
