CBC Bariatric Surgery and Procedures

Question 1

Which bariatric procedure involves removing approximately 80% of the stomach along the greater curvature, leaving a tubular pouch?

Accepted Answer

Sleeve gastrectomy

Answer

Sleeve gastrectomy removes about 80% of the stomach along the greater curvature, creating a banana-shaped tubular pouch.

Question 2

In Roux-en-Y gastric bypass, what is the approximate size of the newly created gastric pouch?

Accepted Answer

About 15-30 mL

Answer

The Roux-en-Y gastric pouch is typically 15-30 mL, roughly the size of an egg, which sharply restricts intake.

Question 3

Which mechanism primarily explains why sleeve gastrectomy reduces hunger beyond simple restriction?

Accepted Answer

Removal of the ghrelin-producing gastric fundus

Answer

The gastric fundus is the main site of ghrelin production, so its removal lowers levels of this hunger hormone.

Question 4

A patient with a BMI of 37 and type 2 diabetes asks whether they qualify for bariatric surgery under the 2022 ASMBS/IFSO guidelines. What is the most accurate response?

Accepted Answer

Yes, surgery is recommended for BMI ≥35 regardless of comorbidities

Answer

The 2022 ASMBS/IFSO guidelines recommend bariatric surgery for BMI ≥35 regardless of comorbidities and consider it for BMI 30-34.9 with metabolic disease.

Question 5

Which bariatric procedure is fully reversible and involves no cutting or stapling of the stomach or intestines?

Accepted Answer

Adjustable gastric banding

Answer

Adjustable gastric banding places a removable silicone band around the upper stomach without cutting or stapling, making it reversible.
