Section snippets
Materials and methods
A detailed search in PubMed for citations that included sleeve gastrectomy, using the keywords “sleeve gastrectomy 5-year weight loss results” found>100 studies. After an initial review of these studies, only 16 reports seemed to match our criteria; a review of these reports was conducted and the full text was reviewed.
Prospective and retrospective series reporting on LSG as a primary or as a staged procedure for the treatment of severe obesity were included if they reported weight loss results
Study characteristics
A total of 16 studies [7], [8], [9], [10], [11], [12], [13], [14], [15], [16], [17], [18], [19], [20], [21], [22] were extracted for the present review. Of the 16 studies, 8 were from Europe, 6 were from the United States, 1 was from Asia, and the remaining originated in Latin America. All studies, except for one [20], were from a single institution. Of the 16 studies, 4 stated clearly that SG was used as part of a staged therapeutic procedure or as a management strategy for a high-risk patient
Discussion
“Durable” weight loss is one important benefit of bariatric surgery, and this is a standard by which success or failure of weight-reducing procedures is measured. One of the most important issues regarding LSG is the durability of the weight loss result several years after the operation and, especially, at 5 or more years postoperatively. Most of the published studies agree that weight regain might be observed in patients after LSG at various time intervals after the operation and can be
Conclusion
LSG may be performed either as part of a staged approach in high-risk patients or as a primary bariatric procedure. The results of the present study show that LSG seems to maintain its well-documented weight loss outcome at 5 or more years postoperatively, with the overall mean %EWL at 5 or more years after LSG still remaining>50%. The existing data support the role of LSG in the treatment of morbid obesity.
