Complications and nutrient deficiencies two years after sleeve gastrectomy.

BACKGROUND: The aim of this systematic study was to investigate patient outcomes and nutritional deficiencies following sleeve gastrectomy (SG) during a median follow-up of two years. METHODS: Over a period of 56 months, all consecutive patients who underwent SG were documented in this prospective, single-center, observational study. The study endpoints included complication rates, nutritional deficiencies and percentage of excess weight loss (%EWL). RESULTS: From September 26, 2005 to May 28, 2009, 100 patients (female: male = 59:41) with a mean age of 43.6 years (range: 22-64) and a preoperative BMI of 52.3 kg/² (range: 36-77) underwent SG. The mean operative time was 86.4 min (range: 35-275). Major complications were observed in 8.0 % of the patients. During the follow-up period, 25 patients (25.0 %) underwent a second bariatric intervention (22 DS and 3 RYGBP). Out of the total 100 patients, 48 % were supplemented with iron, 33 % with zinc, 34 % with a combination of calcium carbonate and cholecalciferol, 24 % with vitamin D, 42 % with vitamin B12 and 40 % with folic acid. The patients who received only a SG (n = 75) had %EWL of 53.6, 65.8 and 62.6 % after 6, 12 and 24 months, respectively. CONCLUSIONS: SG is a highly effective bariatric intervention for morbidly obese patients. Nutritional deficiencies resulting from the procedure can be detected by routine nutritional screening. Results of the study show that Vitamin B12 supplementation should suggested routinely.

Complications, reoperations, and nutrient deficiencies two years after sleeve gastrectomy.

Background. The aim of this study was to investigate patient outcomes and nutritional deficiencies following sleeve gastrectomy (SG) during a follow-up of two years. Methods. Over a period of 56 months, all consecutive patients who underwent SG were documented in this prospective, single-center, observational study. The study endpoints included operative time, complication rates, nutritional deficiencies and percentage of excess weight loss (%EWL). Results. From September 26, 2005 to May 28, 2009, 82 patients (female : male = 48 : 34) with a mean age of 43.3 years (range: 22-64) and a preoperative BMI of 52.5 kg/m² (range: 36.8-77.0) underwent SG. Major complications were observed in 9.8% of the patients, with 1 death. During follow up 51.2% of patients were supplemented with iron, 36.6% with zinc, 37.8% with calcium, 26.8% with vitamin D, 46.3% with vitamin B12 and 41.5% with folic acid. %EWL was 54.3, 65.3 and 62.6% after 6, 12 and 24 months. Conclusion. SG as a single step procedure is an effective bariatric intervention. Nutritional deficiencies after SG can be detected by routine nutritional screening. Our results show that Vitamin B12 supplementation should suggest routinely after SG.
