Complications and nutrient deficiencies two years after sleeve gastrectomy

Area of Science:

• Bariatric Surgery
• Gastroenterology
• Nutritional Science

Background:

• Investigating patient outcomes and nutritional deficiencies after sleeve gastrectomy (SG).
• Assessing the effectiveness of SG in managing morbid obesity.

Purpose of the Study:

• To evaluate patient outcomes, including complication rates and excess weight loss (%EWL), following sleeve gastrectomy.
• To identify and quantify nutritional deficiencies after SG.
• To provide recommendations for nutritional supplementation post-SG.

Main Methods:

• Prospective, single-center, observational study over 56 months.
• Documentation of consecutive patients undergoing SG.
• Endpoints: complication rates, nutritional deficiencies, and %EWL.

Main Results:

• 100 patients (59% female, mean age 43.6) with mean BMI 52.3 kg/m² underwent SG.
• Major complications occurred in 8.0%; 25% required a second bariatric procedure.
• Significant rates of deficiencies: iron (48%), zinc (33%), calcium/Vit D (34%), Vit B12 (42%), folic acid (40%).
• %EWL at 6, 12, and 24 months for SG-only patients (n=75) was 53.6%, 65.8%, and 62.6%.

Conclusions:

• Sleeve gastrectomy is a highly effective bariatric intervention for morbid obesity.
• Routine nutritional screening is crucial for detecting deficiencies post-SG.
• Routine Vitamin B12 supplementation is recommended after sleeve gastrectomy.
