RESUMO
INTRODUCTION: Presently, bariatric surgery is a widespread treatment for obesity and its co-morbidities. Comprehensive evidence from outcomes of bariatric surgery supported that the surgery is safe and effective. However, we should be aware of the multiple risks of bariatric surgery, especially the severe infection at the operation site. CASE PRESENTATION: A 30-year-old woman was hospitalized for anastomotic leakage with abscess after laparoscopic sleeve gastrectomy. After 53 days of percutaneous drainage, absolute diet fasting, parenteral nutrition and culture based antibiotics etc., she was discharged for recovery. DISCUSSION: Theoretically, malabsorption and early diet will increase the risk of anastomotic leakage, but this problem is seldom to be mentioned in related articles. Moreover, it seems to be common that people received bariatric surgery had a relatively short post-operative stay. CONCLUSION: Essential nutritional support, longer post-operative hospital stay and strict follow-up are necessary to minimize this complication.
