The medical management of MO may be effective in the short and intermediate terms, although it usually fails then leading to surgical management. Our goal is to assess Capella's surgical technique by means of quality indicators including weight loss. The present work has been performed with surgical MO patients at the 12 de Octubre University Hospital during 2000-2001, and registering the follow-up checkups for the period 2000-2001/2003-2004. We reviewed the clinical charts of 23 patients. The average Body Mass Index (BMI) was 52.24 ± 10.07 kg/m², (range, 41-74.41). When compiling the statistical results, we observed statistically significant post-surgical decreases with no differences whether the PEIMCP outcome was excellent (≥ 65%), fair (= 50-65%) or failure (≤ 50%) in the following parameters: BMI (p ≤ 0.001); Comorbidities (p ≤ 0.001); Hemoglobinemia (p ≤ 0.005); Glycemia (p ≤ 0.001); Triglyceridemia (p ≤ 0.001); Total cholesterolemia (p ≤ 0.001); Sideraemia (p ≤ 0.001); and serum cianocobalamine (p ≤ 0.001). We could not demonstrate statistically significant changes in the remaining parameters. However, under the presumption that the lack of evidence does not mean the evidence of the absence, that is to say, the results have been obtained from a small sample (N = 23) so that they may not be considered definitely conclusive. Considering the percentage of the loss of Body Mass Index excess as one of the quality indexes in bariatric surgery, we may state that Capella's gastric by-pass is efficient in obese patients with BMI ≤ 50 kg/m², doubtfully effective in patients with BMI 50-60 kg/m², and ineffective in super obese patients with BMI ≥ 60 kg/m².
