Metabolic characterization of nondiabetic severely obese patients undergoing Roux-en-Y gastric bypass: preoperative classification predicts the effects of gastric bypass on insulin-glucose homeostasisRichard A Perugini
Department of Surgery, University of Massachusetts Medical School, Worcester, MA 01655, USA
J Gastrointest Surg 11:1083-90. 2007..Whereas gastric bypass cures insulin resistance and diabetes mellitus, its effects on normal physiology have not been described. We studied insulin resistance and beta-cell function for patients undergoing gastric bypass...
Remission of type 2 diabetes mellitus following bariatric surgery: review of mechanisms and presentation of the concept of 'reversibility'Richard A Perugini

Curr Opin Endocrinol Diabetes Obes 18:119-28. 2011..Roux-en-Y gastric bypass (RYGB) leads to remission of type 2 diabetes mellitus (T2DM) in a majority of patients. This is prompting investigation of RYGB, and other bariatric operations as interventional therapies for T2DM...- Predictors of complication and suboptimal weight loss after laparoscopic Roux-en-Y gastric bypass: a series of 188 patientsRichard A Perugini
Department of Surgery and the Informatics Unit, University of Massachusetts Medical School, Worcester 01655, USA

University of Massachusetts Memorial Health Care, Worcester, Massachusetts, USA
Surg Obes Relat Dis 6:237-41. 2010..We sought to identify the factors predictive of HRV in a severely obese population of undergoing GB at a university hospital in the United States... - Predictors of weight status following laparoscopic gastric bypassYunsheng Ma
Division of Preventive and Behavioral Medicine, Department of Medicine, University of Massachusetts Medical School, Worcester, MA 01655, USA
Obes Surg 16:1227-31. 2006..Weight loss after bariatric surgery varies and depends on many factors, such as time elapsed since surgery, baseline weight, and co-morbidities... 
Body mass index-independent inflammation in omental adipose tissue associated with insulin resistance in morbid obesityOlga T Hardy
Program in Molecular Medicine, University of Massachusetts Medical School, Worcester, Massachusetts 01605, USA
Surg Obes Relat Dis 7:60-7. 2011..We sought to identify the molecular pathways that might cause obesity-associated insulin resistance in humans by studying the morbidly obese who were insulin sensitive versus insulin resistant, thereby eliminating obesity as a variable...- Use of laparoscopy in evaluation and treatment of penetrating and blunt abdominal injuriesGordie K Kaban
Department of Surgery, University of Massachusetts Medical School, Worcester, Massachusetts, USA
Surg Innov 15:26-31. 2008..Use of laparoscopy in selected patients with blunt and penetrating abdominal trauma is safe, minimizes nontherapeutic laparotomies, and allows for minimal invasive management of selected intra-abdominal injuries... - Small-bowel obstruction after laparoscopic Roux-en-Y gastric bypass surgeryGowthaman Gunabushanam
Department of Radiology, University of Massachusetts, Worcester, MA 01655, USA
J Comput Assist Tomogr 33:369-75. 2009..The purpose of this study was to review the etiology and computed tomography (CT) findings of small-bowel obstruction (SBO) in patients who have undergone bariatric laparoscopic Roux-en-Y gastric bypass (LGBP) surgery... - Depot-specific differences and insufficient subcutaneous adipose tissue angiogenesis in human obesityOlga Gealekman
Program in Molecular Medicine, University of Massachusetts Medical School, Worcester, MA 01615, USA
Circulation 123:186-94. 2011..The objective of this study was to measure angiogenesis in visceral and subcutaneous adipose tissue and to establish whether there is a relationship between obesity, metabolic status, and the angiogenic properties of these depots... - Feasibility of laparoscopic adrenalectomy for large adrenal massesYuri W Novitsky
Department of Surgery, University of Massachusetts Medical School, Worcester, USA
Surg Laparosc Endosc Percutan Tech 13:106-10. 2003..Both right and left large adrenal masses can be approached laparoscopically with equal success. The role of minimally invasive approaches to adrenal malignancies necessitates further investigation... - Immunologic effects of hand-assisted surgery on peritoneal macrophages: comparison to open and standard laparoscopic approachesYuri W Novitsky
Department of Surgery, University of Massachusetts Medical School, 55 Lake Avenue North, Ste H1 760, Worcester, MA 01655, USA
Surgery 139:39-45. 2006..Although laparoscopy (L) is known to elicit a smaller attenuation of peritoneal host defenses, compared with open (O) surgery, effects of the hand-assisted (HA) approach have not been investigated to date... - Cidea is associated with lipid droplets and insulin sensitivity in humansVishwajeet Puri
