  • 2. TYPE 2 DIABETES – BACKGROUND Diabetes mellitus is a chronic disease requiring long-term medical attention. Diabetics accounted for 6.2% of the US population in 2002 (18.2 million people). Per capita cost of healthcare: $13,243 for people with diabetes and $2560 for people without diabetes. Pathophysiology - type 2 diabetes typically affects individuals older than 40 years, but has been diagnosed in children as young as 2 years of age. (epidemic of childhood obesity). It is characterized by peripheral insulin resistance with an insulin-secretory defect that varies in severity. About 90% of patients who develop type 2 diabetes are obese. Frequency - 13 million people in the United States have been diagnosed, with another 5 million undiagnosed. Approximately 10% have type 1 diabetes, and the rest have type 2. Complications - hypoglycemia and hyperglycemia, increased risk of infections, microvascular complications (retinopathy, nephropathy), neuropathic complications, and macrovascular disease. Major cause of blindness in adults (20-74 years) / leading cause of nontraumatic lower-extremity amputation and end-stage renal disease (ESRD). Race - more prevalent among Hispanics, Native Americans, African Americans, and Asians/Pacific Islanders than in non-Hispanic whites. Sex - incidence is equal in women and men in all populations.

    • Potential of Surgery for Curing Type 2 Diabetes Mellitus. Rubino, Francesco, MD; Gagner,

    2002: Objective: To review the effect of morbid obesity surgery on type 2 diabetes mellitus, and to analyze data that might explain the mechanisms of action of these surgeries and that could answer the question of whether surgery for morbid obesity can represent a cure for type 2 diabetes in nonobese patients as well. Summary Background Data: Diabetes mellitus type 2 affects more than 150 million people worldwide. Although the incidence of complications of type 2 diabetes can be reduced with tight control of hyperglycemia, current therapies do not achieve a cure. Some operations for morbid obesity not only induce significant and lasting weight loss but also lead to improvements in or resolution of comorbid disease states, especially type 2 diabetes. Methods: The authors reviewed data from the literature to address what is known about the effect of surgery for obesity on glucose metabolism and the endocrine changes that follow this surgery. Results: Series with long-term follow-up show that gastric bypass and biliopancreatic diversion achieve durable normal levels of plasma glucose, plasma insulin, and glycosylated hemoglobin in 80% to 100% of severely obese diabetic patients, usually within days after surgery. Available data show a significant change in the pattern of secretion of gastrointestinal hormones. Case reports have also documented remission of type 2 diabetes in nonmorbidly obese individuals undergoing biliopancreatic diversion for other indications. Conclusions: Gastric bypass and biliopancreatic diversion seem to achieve control of diabetes as a primary and independent effect, not secondary to the treatment of overweight. Although controlled trials are needed to verify the effectiveness on nonobese individuals, gastric bypass surgery has the potential to change the current concepts of the pathophysiology of type 2 diabetes and, possibly, the management of this disease.
  • 4. 2003: Effect of Laparoscopic Roux-En Y Gastric Bypass on Type 2 Diabetes Mellitus Philip R Schauer, MD, Bartolome Burguera, MD, Sayeed Ikramuddin, MD, Dan Cottam, MD, William Gourash, CRNP, Giselle Hamad, MD, George M. Eid, MD, Samer Mattar, MD, Ramesh Ramanathan, MD, Emma Barinas-Mitchel, PhD, R. Harsha Rao, MD, Lewis Kuller, MD DrPH, and David Kelley, MD Annals of Surgery . 238(4): 467-485, October 2003 Objective: To evaluate pre- and postoperative clinical parameters associated with improvement of diabetes up to 4 years after laparoscopic Roux-en-Y gastric bypass (LRYGBP) in patients with type 2 diabetes mellitus (T2DM). Summary Background Data: The surgical treatment of morbid obesity leads to dramatic improvement in the comorbidity status of most patients with T2DM. However, little is known concerning what preoperative clinical factors are associated with postoperative long-term improvement in diabetes in the morbidly obese patient with diabetes. Methods: We evaluated pre- and postoperative data, including demographics, duration of diabetes, metabolic parameters, and clinical outcomes, in all patients with impaired fasting glucose (IFG) and type T2DM undergoing LRYGBP from July 1997 to May 2002. Results: During this 5-year period, 1160 patients underwent LRYGBP and 240 (21%) had IFG or T2DM. Follow up was possible in 191 of 240 patients (80%). There were 144 females (75%) with a mean preoperative age of 48 years (range, 26–67 years). After surgery, weight and body mass index decreased from 308 lbs and 50.1 kg/m2 to 211 lbs and 34 kg/m2 for a mean weight loss of 97 lbs and mean excess weight loss of 60%. Fasting plasma glucose and glycosylated hemoglobin concentrations returned to normal levels (83%) or markedly improved (17%) in all patients. A significant reduction in use of oral antidiabetic agents (80%) and insulin (79%) followed surgical treatment. Patients with the shortest duration (<5 years), the mildest form of T2DM (diet controlled), and the greatest weight loss after surgery were most likely to achieve complete resolution of T2DM. Conclusion: LRYGBP resulted in significant weight loss (60% percent of excess body weight loss) and resolution (83%) of T2DM. Patients with the shortest duration and mildest form of T2DM had a higher rate of T2DM resolution after surgery, suggesting that early surgical intervention is warranted to increase the likelihood of rendering patients euglycemic.
  • 5. 2004: Effect of Duodenal-Jejunal Exclusion in a Non-obese Animal Model of Type 2 Diabetes: A New Perspective for an Old Disease. Rubino, Francesco, MD; Marescaux, Jacques MD, FRCS Annals of Surgery; 239 (1): 1-11, January 2004 Background: The Roux-en-Y gastric bypass and the biliopancreatic diversion effectively induce weight loss and long-term control of type 2 diabetes in morbidly obese individuals. It is unknown whether the control of diabetes is a secondary outcome from the treatment of obesity or a direct result of the duodenal–jejunal exclusion that both operations include. The aim of this study was to investigate whether duodenal–jejunal exclusion can control diabetes independently on resolution of obesity-related abnormalities. Methods: A gastrojejunal bypass (GJB) with preservation of an intact gastric volume was performed in 10- to 12-week-old Goto-Kakizaki rats, a spontaneous nonobese model of type 2 diabetes. Fasting glycemia, oral glucose tolerance, insulin sensitivity, basal plasma insulin, and glucose-dependent-insulinotropic peptide as well as plasma levels of cholesterol, triglycerides, and free fatty acids were measured. The GJB was challenged against a sham operation, marked food restriction, and medical therapy with rosiglitazone in matched groups of animals. Rats were observed for 36 weeks after surgery. Results: Mean plasma glucose 3 weeks after GJB was 96.3 ± 10.1 mg/dL (preoperative values were 159 ± 47 mg/dL; P = 0.01). GJB strikingly improved glucose tolerance, inducing a greater than 40% reduction of the area under blood glucose concentration curve ( P < 0.001). These effects were not seen in the sham-operated animals despite similar operative time, same postoperative food intake rates, and no significant difference in weight gain profile. GJB resulted also in better glycemic control than greater weight loss from food restriction and than rosiglitazone therapy. Conclusions: Results of our study support the hypothesis that the bypass of duodenum and jejunum can directly control type 2 diabetes and not secondarily to weight loss or treatment of obesity. These findings suggest a potential role of the proximal gut in the pathogenesis the disease and put forward the possibility of alternative therapeutic approaches for the management of type 2 diabetes.

    • METHODS: Goto-Kakizaki (GK) type 2 diabetic rats underwent duodenal-jejunal bypass (DJB), a stomach preserving
    • RYGB that excludes the proximal intestine, or a gastrojejunostomy (GJ), which creates a shortcut for ingested nutrients
    • without bypassing any intestine. Controls were pair-fed (PF) sham-operated and untreated GK rats. Rats that had
    • undergone GJ were then reoperated to exclude the proximal intestine; and conversely, duodenal passage was restored
    • in rats that had undergone DJB. Oral glucose tolerance (OGTT), food intake, body weight, and intestinal nutrient
    • absorption were measured.
    • RESULTS : no differences in food intake, body weight, or nutrient absorption among surgical groups. DJB-treated rats
    • had markedly better oral glucose tolerance compared with control groups as shown by lower peak and area-under-the
    • curve glucose values (P < 0.001 for both). GJ did not affect glucose homeostasis, but exclusion of duodenal nutrient
    • passage in reoperated GJ rats significantly improved glucose tolerance. Conversely, restoration of duodenal passage
    • In DJB rats reestablished impaired glucose tolerance.
    • CONCLUSIONS: “bypassing a short segment of proximal intestine directly
    • ameliorates type 2 diabetes, independently of effects
    • on food intake, body weight, malabsorption, or nutrient
    • delivery to the hindgut. These findings suggest that a
    • proximal intestinal bypass could be considered for
    • diabetes treatment and that potentially undiscovered
    • factors from the proximal bowel might contribute to
    • the pathophysiology of type 2 diabetes”

    • Duodenal jejunal bypass for adult, non-obese patients, holds an exciting non-drug maintenance alternative to adults suffering from type 2 diabetes.
    • We will continue to publish post-surgical updates on these patients as we monitor their blood enzyme levels over the two year clinical study time frame.
    • If this operation proves effective, then we look forward to it technically handled in 2 ways:
      • A. Endoscopic plication of the pylorus followed by laparoscopic gastrojejeunostomy
      • B. N.O.T.E.S. - Endoscopic plication of the pylorus followed by endoscopic transgastric gastric jejeunostomy
