ANSWERS
CSOWM - BARIATRIC SURGERY PROCEDURES &
NUTRITION | ACTUAL EXAM QUESTIONS AND ANSWERS |
LATEST UPDATE 2026/2027 | GRADED A+.
One Anastomosis Gastric Bypass (OAGB) Disadvantages -
<<<Answers>>>>- potential for malnutrition
- bile reflux esophagitis
- limited data >5 years to identify long term nutrition
concerns
Laparoscopic Adjustable Gastric Banded Plication (LAGBP) -
<<<Answers>>>>combines LAGB with vertical SG
- stomach below the band is plicated (rolled into itself and
sewn together)
Laparoscopic Adjustable Gastric Banded Plication (LAGBP)
Advantages - <<<Answers>>>>- low morbidity
- similar weight loss to VSG
- reversible (since no resection)
, CSOWM - BARIATRIC SURGERY PROCEDURES
& NUTRITION (ACTUAL 2025) QUESTIONS AND
ANSWERS
-
Sleeve Gastrectomy (SG) Advantages - <<<Answers>>>>-
performed more quickly which means shorter anesthesia
duration and lesser degree of post op systemic response
- fewer complications
- decreased risk of micro-nutritional problems
- decreased risk of long term complications (obstructions,
ulcers, dumping syndrome, hypoglycemia, etc)
- can be revised/converted
- allows access to both biliary & pancreatic duct (for upper
GI/EGD)
- favorable change in the gut microbiota.
Sleeve Gastrectomy (SG) Disadvantages & Risks -
<<<Answers>>>>- may exacerbate GERD due to preservation
of acid producing cells
- unknown long term data (10+ years) regarding durability of
weight loss and comorbidity improvements
- contraindicated in patients with severe GERD, lower
esophageal sphincter incompetence, and Barrett's
esophagus
, CSOWM - BARIATRIC SURGERY PROCEDURES
& NUTRITION (ACTUAL 2025) QUESTIONS AND
ANSWERS
Combination Procedures - <<<Answers>>>>Gastric
manipulation, causing some restriction and neural/hormonal
changes
Roux-en-Y Gastric Bypass (RYGB) - <<<Answers>>>>Step 1
Restriction: The surgeon separates the upper portion of the
stomach from the lower portion. The upper portion (or the
"pouch") is then connected to a limb of the small intestine,
called the "Roux limb." The new stomach pouch restricts the
amount of food you can eat, making you feel full after eating
only a small amount of food.
Step 2 Malabsorption: The pouch is then connected to the
middle of the small intestine (the jejunum) - the duodenum
and part of the jejunum are bypassed.
Roux-en-Y Gastric Bypass (RYGB) Mechanisms -
<<<Answers>>>>Ghrelin Suppression
, CSOWM - BARIATRIC SURGERY PROCEDURES
& NUTRITION (ACTUAL 2025) QUESTIONS AND
ANSWERS
-
- nutrient exposure to the intestine is sufficient for
foodinduced ghrelin suppression - it may cause partial
vagotomy
Bariatric and Metabolic Surgery Procedures -
<<<Answers>>>>- Previously known as weight loss surgery
- Impact the physiological regulation of body weight
- Improve morbidity and mortality rates among
overweight/obese populations
Examples: Sleeve Gastrectomy (SG), Roux-en-Y Gastric
Bypass (RYGB), and Biliopancreatic Diversion (BPD/DS)
Sleeve Gastrectomy (SG) - <<<Answers>>>>80% of stomach is
removed (specifically the fundus, which significantly reduces
ghrelin production)
