Bariatric Surgery Flashcards
Candidates for a bariatric surgical procedure are
a grosso modo
adults with a morbidly high body mass index (BMI),
Candidates for a bariatric surgical procedure are specifically:
BMI ≥40 kg/m2 without comorbid illness
BMI 35.0–39.9 kg/m2 with at least one serious comorbidity (type 2 diabetes, fatty liver disease, hypertension)
The most common contraindication to bariatric surgery is
untreated major depression, untreated psychosis, or uncontrolled and untreated eating disorders
the most commonly performed bariatric procedure is
Sleeve gastrectomy
the bariatric qx options are
Roux-en-Y gastric bypass,
Sleeve gastrectomy
Gastric band
Sleeve gastrectomy is
a partial gastrectomy in which the majority of the greater curvature of the stomach is removed and a tubular stomach is created
The most common adverse effects of Sleeve gastrectomy are
narrowing or stenosis of the remnant stomach, leaks, and severe GERD
due to a change in the angulation of the esophagus in relation
to the stomach.
In Roux-en-Y gastric bypass, a ______ is created and connected to ______
small gastric pouch
a limb of small bowel
how Roux-en-Y gastric bypass works
by decreasing the volume of food intake because the stomach is smaller and decreasing absorption by reducing the total small bowel area.
Roux-en-Y gastric bypass most common adverse effects are
marginal ulcer formation, cholelithiasis, dumping syndrome, and weight regain.
Gastric band surgery is
a purely volume-decreasing procedure in which an
adjustable silicone device squeezes the gastric cardia near the gastroesophageal
junction,
Gastric band surgery, how it works
by limiting the amount of food that it can contain.
Volume restriction can
be increased by slowly tightening the band over time.
Gastric band surgery Common adverse effects are
band erosion into the stomach and slippage of the band off the stomach
