Prevalence of Obesity, Dyslipidemia and Diabetes Mellitus in Patients with Gastrojejunostomy

Billroth Gastrojejunostomy (GJ) is less invasive surgery as compared to Roux-en-Y Gastric Bypass (RYGB), which is performed for obesity and weight loss. There is sparse data on long term metabolic effects of GJ, which was performed frequently in the past. Aim: To determine the prevalence of obesity, dyslipidemia and Diabetes Mellitus (DM) in patients that had undergone GJ. Materials and Methods: This was a cross-sectional study conducted in the Department of Gastroenterology, Government Medical College, Calicut, Kerala, India, over a period of six years. All patients with history of GJ, done in past 15 years were included in the study. Presence of obesity, DM and dyslipidemia were noted among patients and was compared with their first degree relatives. Patients with family history of diabetes and without first degree relative were excluded from the study. Statistical analysis was performed using Chi-square test for qualitative variables and independent t-test for quantitative variables. Significance level was fixed as p-value of <0.05. Results: A total of 68 patients were studied. Mean age of patients was 64.01±10.2 years with males predominating the population (92.6%). The most common three reasons for presentation in gastroenterology were dyspeptic symptoms 32(47%), evaluation of anaemia 12 (17.6%), and history of malena 10(14.7%). Prevalence of diabetes was significantly less in patients with GJ (2.9% vs 22%). Obesity and dyslipidemia was also common in patients without GJ (7.3%), with p-value <0.05. Conclusion: Prevalence of obesity, DM and dyslipidemia is significantly lower in patients with GJ.
