CBC Bariatric Surgery and Procedures Questions and Answers

Question 1

A bariatric procedure involves surgically removing approximately 75-80% of the stomach along the greater curvature, creating a narrow, tube-like stomach without bypassing the intestines. Which procedure is this?

Accepted Answer

Sleeve Gastrectomy (SG)

Answer

The Sleeve Gastrectomy (SG) is a restrictive procedure where a large portion of the stomach is permanently removed, creating a smaller, sleeve-shaped stomach. [2, 4, 6] This reduces food intake capacity and favorably impacts gut hormones that regulate hunger, like ghrelin. The other procedures involve either placing a band (AGB) or bypassing parts of the intestine (RYGB, BPD/DS). [24]

Question 2

A patient who underwent a Roux-en-Y Gastric Bypass (RYGB) six months ago reports experiencing nausea, cramping, dizziness, and a rapid heartbeat within 30 minutes of eating a meal high in sugar. What is the most likely cause of these symptoms?

Accepted Answer

Dumping syndrome

Answer

Dumping syndrome is a common complication after RYGB, caused by the rapid passage of concentrated food, particularly sugars, from the small stomach pouch directly into the small intestine. [12, 28] This triggers a fluid shift and hormonal response, leading to the described gastrointestinal and vasomotor symptoms. [29]

Question 3

Which of the following bariatric procedures creates weight loss through a combination of restriction and the most significant degree of malabsorption, putting patients at the highest risk for protein and fat-soluble vitamin deficiencies?

Accepted Answer

Biliopancreatic Diversion with Duodenal Switch (BPD/DS)

Answer

The Biliopancreatic Diversion with Duodenal Switch (BPD/DS) is the most powerful procedure for weight loss, primarily due to its significant malabsorptive component. [5, 17] It bypasses a large portion of the small intestine, severely limiting the absorption of calories, fat, and fat-soluble vitamins (A, D, E, K), which necessitates rigorous, lifelong supplementation and monitoring. [8, 19]

Question 4

A bariatric counselor is educating a patient about the typical post-operative diet progression. What dietary stage does a patient enter IMMEDIATELY following surgery to allow for initial healing?

Accepted Answer

Clear liquids only

Answer

The immediate post-operative diet (Stage 1) consists of only clear liquids, such as water, broth, and sugar-free gelatin. [7, 10, 20] This approach minimizes stress on the new staple lines, prevents dehydration, and allows the stomach to begin healing before advancing to thicker liquids and more complex foods.

Question 5

During a pre-surgical evaluation, a bariatric candidate discloses an ongoing, untreated substance abuse disorder involving heavy daily alcohol use. According to ASMBS guidelines and general clinical practice, this condition is considered a(n):

Accepted Answer

Absolute contraindication requiring treatment and sobriety before reconsideration

Answer

Active, untreated alcohol or drug dependency is widely considered an absolute contraindication for bariatric surgery. [11, 25] It poses significant risks during and after surgery, severely impairs the patient's ability to adhere to the required post-operative lifestyle changes, and increases the risk of addiction transfer. The condition must be treated, with a demonstrated period of sobriety, before surgery can be safely considered.
