Dr. Vivek Prachand is an expert in minimally-invasive gastrointestinal surgery with a special interest in minimally invasive obesity surgery. In addition to performing the laparoscopic Roux-en-Y gastric bypass, Adjustable Gastric Banding, and Vertical Sleeve Gastrectomy procedures, in 2002 he was the first surgeon in the Midwest to perform a totally laparoscopic biliopancreatic diversion with duodenal switch, and is one of a handful of surgeons in the world who regularly performs the laparoscopic duodenal switch for “super-obese” and “super-super-obese” patients (individuals with BMI > 50 kg/m2 and BMI > 60 kg/m2, respectively). Of particular interest to Dr. Prachand is the development of an evidence-based algorithm for bariatric procedure selection based on the severity of obesity and its associated co-morbidities, particularly in the setting of super-obesity, which is the group most rapidly increasing in prevalence and which historically has been the most difficult to treat medically or surgically. Accordingly, a major research interest of Dr. Prachand’s is the comparative examination of the mechanisms and effects of the different bariatric procedures on the pathophysiology of obesity and its related comorbidities, including diabetes, hypertension, dyslipidemia, metabolic syndrome, obstructive sleep apnea, and gastroesophageal reflux.
