The aim of this study is to evaluate the long-term (5-year follow-up) results of laparoscopic gastric sleeve (LGS) in terms of weight loss and obesity related comorbidities, as well as the risk factors associated with postoperative nutritional deficiencies.
The consecutive patients who undergo LGS for the treatment of morbid obesity at Tartu University Hospital are followed prospectively in cohort study. The outpatient hospital follow-up visits are conducted at 3 months, 1 year and 5 years postoperatively.

RECRUITINGFive-year outcome of laparoscopic gastric sleeve
5-year outcome in terms of weight loss, calculated in mean excess weight lost (%EWL).
Time frame: 5-year follow-up
Five-year outcome of laparoscopic gastric sleeve
5-year outcome of resolution of obesity-related comorbidities (type 2 diabetes mellitus, hypertension, obstructive sleep apnea, dyslipidemia). Prevalence of comorbidities are presented in percentages. McNemar´s test is employed to analyse significance of resolution of comorbidities.
Time frame: 5-year follow-up
Five-year outcome of laparoscopic gastric sleeve
5-year risk for cumulative nutritional deficiencies. According to blood analysis results and patient provided information about taking supplementations (eg vitamine B12 or iron), prevalence of nutritional deficiencies are calculated in percetanges. Backward stepwise logistic regression is used to evaluate the risk factors for nutrition.
Time frame: 5-year follow-up
