Diabetes

• Considered major public health problem – emerging as a world wide pandemic. In 1995 ~ 135 million people worldwide

• Expected to rise to close to 300 million by 2025 • CDC (2008) cases of diabetes have increased to 15% in just the past

two years • 2002-Annual direct health care cost was estimated to be $132 billion

in US • Complications

– Peripheral vascular disease (PVD) accounts for 20-30% – 10% of cerebral vascular accident – Cardiovascular disease accounts for 50% of total mortality – Retinopathy, ESRD

Prevalence of Diabetes

• From 1980 through 2005, the number of adults aged 18-79 with newly diagnosed diabetes almost tripled from 493,000 in 1980 to 1.4 million in 2005 in the United States

• Annual number (in thousands) of new cases of diagnosed diabetes among adults aged 18-79 years, United States, 1980–2005

Long-term Weight Control Analysis

Schauer et al.Effect of laparoscopic Roux-en Y gastric bypass on type 2 diabetes mellitus.

Ann Surg. 2003 Oct; 238(4): 467-84

• 1160 patients underwent LRYGBP 5-year period

• LRYGBP resulted in significant weight loss (60% percent of excess body weight loss) and resolution (83%) of T2DM

• Fasting plasma glucose and HBA1C normalized (83%) or markedly improved (17%) in all patients

• 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

Biliopancreatic Diversion (BPD)

• 312 BPD, obese patients with type 2 DM were followed for pre and postoperative serum glucose, triglycerides, cholesterol & arterial pressure measurements

• After BPD, fasting serum glucose fell within normal values in 310 patients; remained normal up to 10 years in all but 6 patients

• Evidence of hypertension disappeared in majority of patients

• Glycemic control translates into a reduced mortality for these patients as well as a low frequency of death from cardiovascular events

Dixon et al.Adjustable Gatric Banding and conventional therapy for type 2

diabetes: a randomized control trial JAMA 2008

• Un-blinded randomized control trial

• 60 obese patients (BMI >30 & <40) with T2DM

• Interventions:

-Conventional diabetes control with lifestyle modification vs. LAGB

• Results:-55 (92%) completed with 2 year follow-up

-Remission of diabetes was achieved in 73% in surgical group and 13% in the conventional-therapy group

Dixon et al.Adjustable Gatric Banding and conventional therapy for type 2

diabetes: a randomized control trial JAMA 2008

• CONCLUSIONS: • Participants randomized to surgical therapy were

more likely to achieve remission of type 2 diabetes through greater weight loss.

• These results need to be confirmed in a larger, more diverse population and have long-term efficacy assessed.

2002: Antidiabetic Effect of Bariatric Surgery: Direct or Indirect?

1995-“Who Would Have Though It?Pories et al. Annals of Surgery

• NIDDM is no longer an uncontrollable disease

• The correction on NIDDM occurs within days following gastric bypass, long before significant weight loss has occurred

• Decrease caloric intake and changes in incretin stimulation of the islets by the gut may play a role

Historical Perspective• 1955- Friedman

– 3 patients with poorly control DM – 3-4 days after subtotal gastrectomy: all 3 pateints showed an improvement in their

DM • Occurred sooner than associated weight loss• Patients later regained their weight without an associated loss of glucose

control or glycosuria

• Mingrone 1977 : Case report – Young, non obese woman with DM who underwent BPD for chylomicronemia– Plasma insulin and blood glucose levels normalized within 3 months

• Bittner –1981- subtotal gastrectomy and gastrointestinal reconstructions that excluded duodenal passage (B2 and RYGB)– Lowered plasma glucose and insulin – Conclusion: Plasma glucose and insulin fall rapidly post-operatively

• antidiabetic medications can be reduced or stopped shortly after gastrointestinal bypass interventions

DISCOVERY OF GASTROINTESTINAL HORMONES

How Does Bariatric Surgery Effect glucose homeostasis?

1. Intestinal Malabsorption?• Weight loss reduces insulin resistance• Glucose malabsorption reduces stress on islet cells• Fat malabsorption reduces circulating free fatty acids and

improves insulin sensitivity

2. Hormonal Changes?Re-routing of food alters the dynamic of gut-hormone secretion• Increased levels of glucagon-like peptide 1 (GLP-1)• Decrease in plasma levels of leptin & Grhelin• Increased levels of adiponectin & peptide YY3-36

3. Rearrangement of GI anatomy?• “Hindgut hypothesis”• “Foregut hypothesis”

1. Pathophysiology

Excess adipose tissue increasesavailable triglyceride stores

Breakdown of TG leads to overabundanceof circulating fatty acids

• Bariatric Surgery clearly has an antidiabetic effect

• Direct effect of the surgical bypass of proximal intestines

• Hormonal Regulation of Glucose Metabolism

• Insulin, glucagons-like peptide (GLP-1), glucose-dependent insulinotropic peptide (GIP), glucagon and leptin

2007: Pacheco Bypass & Glucose Metabolism

Animal Model of DJ Bypass and Glycemic Control

• Animal Model of non-obese type 2 diabetes; Goto-Kakizaki rats• Twelve (12-14 wk old) rats randomly underwent gastrojejeunal bypass or no intervention * All fed with same type of diet * All fed with same amount of diet * Pre-op, post-op 1 wk & 1 month weight assessment & fasting glycemia * Oral Glucose Tolerance Test performed at each time point * Hormone levels were measured after 20 minutes of oral overload

2007- Results of DJ Bypass on Glycemic Control

• Group 1 and Group 2 rats remained the same weight during the experiment

• OGTT improved in DJ bypass group• Glucose levels were better at 1 week & 1

month after DJ bypass in all times of OGTT (basal, 10 min, 120 min)

• Post-oral glucose load levels of glucagon, insulin, GLP-1 and GIP remained unchanged in both groups

• In DJ bypass group there is a significant decrease in leptin levels noted

Leptin???

• Adipocyte-derived hormone

• In mice, leptin acts as a hormonal signal on the afferent limb of a negative feedback loop between the adipose tissue and hypothalmic centers

• Physiological increase in plasma leptin has been shown to significantly inhibit glucose-stimulated insulin secretion in vivo and to determine insulin resistance

• 2 patients with c-peptide <1, the HbA1c increased following the procedure

SAGES 2008

• 35 patients T2DM for 2-10 years l underwent LDJB• April-Nov 07• 15 women, 20 men• Comorbidities

– 75% with HTN– 58% Hypercholesteremia– 62.5% Hypertriglyceremia

• Mean OR time = 46 minutes (33-78 min)• Hospital stay 30 hrs –81 days• PPI for 90 days• Patients kept on metformin/glimeperide (metformin withdrawn when

HBA1c <6)

Complications

• 1 death

• 2 intestinal obstruction

• 1 pos-operative pancreatitis

• 2 intracavitary bleeding

Results

• HbA1c decreasing from 8.9 to 6.1.

• 72.3% of patients had control of their hypertension: reduced sympathetic outflow?

• 13/35 patients reported food intolerance: 8/13 required admission

(no women)

• Oral Ginger and sildenafil are very helpful

• 75% complained of post-prandial sleepiness– These side effects may be attributed to gastroparesis and the

postulated diminished sympathetic outflow, a result of central leptin suppression and duodenal bypass

Interim Conclusions

Very promising initial experience.

The vast majority of insulin users do not use it anymore very early in the post-op.

In most of those patients with overweight or grade 1 obesity, weight loss is not a major player regarding the control of T2DM, as some had no weight modification or regained weight and there was no recurrence.

Interim Conclusions

What are the correct inclusion/exclusion criteria? Should we cut off at 8, 9, 10 years?

Time of T2DM history does not seem important, but C peptide below 1 YES!!!

Interim Conclusions

Don’t rush to withdraw medication.

We add an incretin effect, but METFORMIN helps to decrease hepatic defective glucose production.

What is the antidiabetes mechanism?

Interim Conclusions

What are the appropriate limb lengths? 50/75/80?

Is it necessary to bypass the entire duodenum? If yes, how can we assess that? Does it make any difference?

Do we need complex operations in this subset of patients? Are the mortality/ complication rates reasonable?

Will an added sleeve gastrectomy in selected patients be needed to avoid gastroparesis, mainly in those with BMI>32? Or is a LRYGB more adequate?
