Long-term (11+ years) efficacy of sleeve gastrectomy as a stand-alone bariatric procedure: a single center retrospective observational study
Bibliographic record
Abstract
Abstract Introduction: Sleeve gastrectomy (SG) is currently the most commonly performed bariatric procedure worldwide. The aim of the present study was to evaluate the long-term efficacy of SG as a stand-alone bariatric procedure. Methods: A single center retrospective analysis of 104 patients who underwent SG as a stand-alone bariatric procedure between January 2005 and December 2009. Weight loss, weight regain, remission or improvement of comorbidities, and the new onset of comorbidities were the main outcomes of the study. Results: At a mean follow-up of 13.4 years, % excess body weight loss (%EBWL), % excess BMI loss (%EBMIL) and % total body weight loss (%TBWL) were 59 ± 25, 69 ± 29 and 29 ± 12, respectively. Approximately two third of patients (67.3%) maintained an %EBWL of > 50 at the last follow-up. The percentage of patients who experienced significant weight regain ranged from 47% to 64%, depending on the definition used for weight regain. The rate of improvement or remission of hypertension, type 2 diabetes, dyslipidemia, obstructive sleep apnea and degenerative joint disease at a mean follow-up of 13.4 years was 40%, 94.7%, 70%, 100% and 42.9%, respectively. The new onset of gastroesophageal reflux disease (GERD) in the same period was 43%. Conclusion: Our data support that SG results in long-lasting weight loss in the majority of patients and acceptable rates of remission or improvement of comorbidities. Weight regain and GERD may be issues of particular concern during long-term follow-up after SG.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
