Our results following SG and those reported in the literature are promising. Adequate long-term results are still unavailable because long-term studies (> 6 years) are rarely performed. The effectiveness and safety of SG are encouraging.

The operative treatment is not comparable among studies because of a lack of standardization.[9] Also, the 3rd International Consensus Statement on Sleeve Gastrectomy could not recommend which part of the antrum should be left and to what degree the antrum should be minimized to achieve a long-term volume reduction in the sleeve.[8] Evidence-based data are unavailable concerning the size of the bougie or whether the use of staple line reinforcement could reduce the rates of leakage.[18]

Our data suggest:

SG is an effective intervention for weight loss. For patients with a BMI of 35–49.9 kg/m2, a single-step procedure is suitable. For patients with a BMI > 50 kg/m2, SG is suitable as a first-step procedure for reducing perioperative risks for DS.[8,17]

for patients with BMI > 60 kg/m2, preoperative implantation of a gastric balloon should be discussed with the aim to reduce morbidity and mortality.

Supplementation of vitamin B12 is indicated and should generally be initiated after SG.

Supplementation of iron and folic acid should depend on laboratory parameters for both genders.

A deficiency in albumin was not reproducible in our patients.

Supplementation of zinc should be based on symptoms.

Substitution of selenium is not necessary.
