Post Operative Care/Considerations of the Bariatric Patient in Primary Care

Slide 3

Identify obesity as a major health problem Describe the socio-economic impact on people who suffer from morbid obesity Discuss the surgical options for obesity. Identify key components to the pre-operative evaluation of bariatric patients. Discuss the after care of the surgical bariatric patient including laboratory and GI tests Discuss post operative complications that may appear in the primary care office.

Slightly underweight insects, fish, reptiles, birds, mammals and people live longer than the overweight. To lengthen thy life, lessen thy meals. Benjamin Franklin

Slide 5

Obesity- over ideal weight by 30% or BMI over 30 Morbid Obesity- Clinically severe obesity-point where serious medical conditions occur as a direct result of the obesity Defined as >200% of ideal weight, >100 lb overweight, or a body mass index of 40

Slide 6

Eating out/ordering in & foods not healthy Portion sizes increased (soda 6 oz to 20oz) Consumption of soft drinks (600 12 oz/pp/per year, males 12y-29y=1/2 gal/d or 160 gal/yr) Rushed meals Junk food is advertised, cheap and available No time to exercise Technology especially for children Unrealistic expectations

Slide 7

Body Mass Index (BMI) BMI = Formula: weight (lb) / [height (in)]2 x 703 Calculate BMI by dividing weight in pounds (lbs) by height in inches (in) squared and multiplying by a conversion factor of 703. Example: Weight = 150 lbs, Height = 55 (65") Calculation: [150 (65)2] x 703 = 24.96 W.H.O. Classification BMI Ideal Weight 20 24.9 Overweight 25 29.9 Moderate Obesity 30 34.9 Severe Obesity 35 39.9 Morbid Obesity 40 49.9 Super Obesity 50+++ (MenWaist 40 inches Women Waist 35 inches) More adverse health effects with increased fat inside the abdominal cavity.

Slide 8

World epidemic of obesity - Estimated about 1.7 billion people - 25% of industrialized world 97 million Americans (> 2/3 population) are overweight/obese. Has tripled in last 20 years. Obesity costs in US about $100 billion/yr in direct health care expenses/lost productivity. 300,000 deaths annually in US obesity related.1 in 6 morbidly obese people will die within 10 years. (from research Ohio State University) Less than 2% morbidly obese people will succeed in loosing and keeping off weight with diet and exercise on their own.

Slide 11

Discrimination Studies show society has low respect for morbidly obese Many have limited number of friends Many obese individuals report being treated disrespectfully by an M.D. Social isolation, depression & low esteem

Slide 12

Weight loss surgery is not a magic pill. It will not make you suddenly slim, happy, & beautiful or give you a perfect life. It is a tool to assist you and is a part of an entire program to help you lose the your excess weight. WLS can make you healthier and decrease your risk of early death associated with obesity.

Laparoscopic duodenal switch Laparoscopic RNY Gastric Bypass Laparoscopic Adjustable Gastric Band Laparoscopic Sleeve Gastrectomy Revision surgery - Conversion from band to RNY or Sleeve - Conversions from VBG to RNY - Failed previous RNY

Slide 14

Slide 15

Most durable technique, been performed in some variations since 1967 Most studied, best understood good programs will provide best long-term maintenance Requires modification of food preferences enforced by dumping syndrome Laparoscopic versions preferred, much easier on patient 75-80% EWL at three years It is reversible Negatives: higher initial complication rate (lower late complication rate), need to supplement vitamins and minerals for life, potential for malnutrition with non-compliance

Slide 16

Early (any abdominal pain, get CT scan) Staple line leak (0.25-3%), most occur 3-12 days post-op, rare after 3 weeks. GI bleeding - (0.5-5%), usually from staple lines Dilated loops (2-5%), ileus, SBO, internal hernia, kinks; worry is perforation of bypassed stomach Death (0.2%) first 30 days either PE or bowel leak

Slide 17

Vitamin deficient Common are Vitamin B12, Calcium, Folic Acid Some food intolerance & alcohol - more rapidly absorbed and can lead to early intoxication. Dumping syndrome-especially after large amounts of sugar. Symptoms=heart racing, sweating, nausea, stomach cramps, diarrhea, fatigue Bowel obstructions - 1%+Caused by Internal Hernia CT Scan for dx. dilated bypassed stomach, dilated small bowel, deviated SMA vessels dx laparoscopy Stricture/Stenosis (2-8%), if cannot keep down H20 suspect stricture diagnosed by UGI, EGD (rare after 3 months unless smoker) Ulcers of pouch - 1% (Smokers), double with NSAID use, diagnose with EGD Cholelithiasis gallbladder sonogram (5 - 25%), rare before 6 weeks post-op, increases w/ excessive fats or dairy in diet (Ursodial)

Slide 18

Average weight loss of 77% at one year. After 10-14 years approx. 70% patients have maintained approximately 70% of their weight loss. 96% of patients saw a reduction or resolution of co-morbidities.

Slide 19

Restrictive (limits amount of food eaten) Adjustable can adapt to changing needs Low immediate complication rate (higher later complication rate) Easy on patient outpatient surgery Less dependent upon supplementation Slow but steady weight loss 1-2 lbs. per week, average 40-60% EWL at three years Negatives Half of patients only reach 50% EWL mark, requires lots of maintenance, doesnt reinforce food choices; frequent adjustments needed, slip, erosion, esophageal dilatation, and port problems

Slide 20

Slide 21

Slippage (Prolapse) 2 10% Port Problem 2 7% Erosion 0.5 1% Esophageal Dilation 1 2% Death 1 IN 1500 from pulmonary emboli Greater Chance re-operation Persistent dysphagia Up to 25% of bands being removed after 5 yrs.

Slide 22

Slide 23

Bleeding from suture line (0-6.4%) Gastric leak from suture line (1-1.4%) Excess narrowing or post op stricture (1-2%) Pouch dilatation over time (5-10%) Post op nausea (usually goes away in 2 week Post op heartburn (27 with one co-morbidity Do not use preg./breast feeding, glaucoma, hyperthyroid Phendimetrazine (Bontril) 35mg/ 2-3 x daySame as phenteramine

Slide 29

Skin hygiene-document with pictures in the medical record Proper nutrition (60 grams of protein and 60 oz of fluids/day) Proper vitamins- if hospitalized then use a banana bag daily Medicines should be taken one at a time with plenty of water in-between. Avoid NSAIDS and aspirin but if have to take aspirin it should be chewable. Checking laboratory data periodically as recommended. Never put down an NG tube Encourage pt not to smoke!

Slide 31

36 y/o female presents to your office with 2 year history of gastric banding c/o dry cough especially at night when lying down, heart burn, GERD for last 2 weeks. Now c/o productive cough with temperatures of 100.6. VS 144/90-100.8-100-28. pulse ox=94%. CBC shows WBC of 14.3 with slight shift to left. PE unremarkable except rales at left base. Had a fill 3 weeks ago. What is the most likely diagnosis? What do you think is going on? What is your plan of care?

Slide 32

You order a chest x-ray and is shows pneumonia which you treat with antibiotics, rest and plenty of fluids. You ask her to follow up in one week. What is the next step in the care of this patient?

Slide 33

48 y/o female with history of gastric bypass 18 months ago and has done very well with losing over 110 lbs and is now at her goal weight. She presents to your office with persistent abdominal pain that is worse after eating and occurs almost every time after eating for the last 3 weeks and progressively getting worse. Occasional waive of nausea but no vomiting and bowels are moving normally maybe slightly slower but no constipation. PE is normal except tenderness at mid to left abdominal pain above the umbilicus VS wnl. CBC, CMP, UA all normal What is your next step? What do you think is going on?

Slide 34

You first order a gallbladder sonogram which is normal. Then you order a CT scan of the abdomen and it shows an internal hernia. What is your next step and what usually will be done in this case?

Slide 35

32 y/o female presents to the officewith abdominal pain and distention, nausea and vomiting and no BM for 3 days. She is 9 months post op gastric bypass. VS-138/88- 98.8-94-24 What test should be ordered? What do you think is going on?

Slide 36

You order a obstruction series and it shows a small bowel obstruction. What would be your next step?? What would normally happen with this patient??

Slide 37

Obesity is a chronic disease Modest weight loss (5% -10% of body weight) can have considerable medical benefits Lifestyle change (diet behavioral changes and physical activity) is the cornerstone of therapy Pharmacotherapy can be useful in properly selected patients Bariatric surgery is the most effective therapy for obesity
