Laparoscopic Sleeve Gastrectomy: Outcomes, Safety and Complications

Abstract

Worldwide, the numbers of laparoscopic sleeve gastrectomy (LSG) performed grown exponentially over the last decade, because of its simplicity, safety profile and excellent outcomes in terms of durable weight loss and improvement of obesity-associated comorbidities. This chapter will provide a comprehensive review on the outcomes of LSG as a metabolic surgery. It appraises LSG\'s short, mid and long term weight loss outcomes, and compares these outcomes with those of other types of bariatric surgery. Then, a wider range of LSG outcomes are discussed, including a variety of comorbidities, clinical, biochemical and inflammatory parameters, while appraising the positive metabolic effects of LSG. The chapter also outlines the issues pertaining to LSG among a range of special populations such as adolescents, the elderly, renal transplant patients and others. The chapter concludes with a review of the safety and most common complications that may be encountered in the short term and long term, including surgical and nutritional complications, as well as mortality.

Factors influencing body weight one year after bariatric surgery

“…[18] Another study found that the mean %EWL was approximately 60% 1 year after surgery. [21] This study found a positive correlation between excess weight loss and time, expressed as %EWL. Furthermore, the study observed that participants' weight loss was continuous during the first year.…”
