ABSTRACT
OBJECTIVE: To report an overview of bariatric & metabolic surgery performed in 2018 in North China. METHODS: Based on prospective and observational North China Bariatric & Metabolic Surgery Clinical Database(NC-BMD), the study of evaluating the number and the type of bariatric &metabolic surgery procedures was performed in North China. Demographic characteristic, obesityrelated diseases and operational information were also analyzed. RESULTS: In 2018, 17 centers from 7 regions in North China contributed a total of 728 registration data. Valid data were analyzed from 16 centers. The patients' median (minimum, maximum) BMI pre-surgery was 38.4(24.7,95.2). The overall proportion of female patients was 74.7%, and mean±SD age was(32.5±8.29) years, while male patients was 25.3%, and mean±SD age was (32.7±9.90) years. According the data 93.9% laparoscopic sleeve gastrectomy(LSG), 4.4% laparoscopic Roux-en-Y gastric bypass (LRYGB) and 1.7% other operation types. 29.2% of patients had a history of type 2 diabetes, 69.4% had sleep apnea, and 22.6% had polycystic ovary syndrome before operation. CONCLUSION: The establishment of NC-BMD has laid a solid foundation for data registration in North China. Based on current data, LSG is the mainstream of bariatric and metabolic surgery in North China this year.
