Free CBE Bariatric Surgery Procedures & Techniques Questions and Answers — Questions and Answers
Question 1: Which of the following bariatric procedures involves creating a small stomach pouch and bypassing part of the small intestine?
- Sleeve gastrectomy
- Adjustable gastric banding
- Roux-en-Y gastric bypass (Correct answer)
- Intragastric balloon
Correct answer: Roux-en-Y gastric bypass
The Roux-en-Y gastric bypass (RYGB) is a bariatric procedure that involves creating a small stomach pouch and then connecting it directly to a section of the small intestine, bypassing the majority of the stomach and the first part of the small intestine. This alters both food intake and nutrient absorption, leading to significant weight loss.
Question 2: What is the primary goal of sleeve gastrectomy?
- Prevent nutrient absorption
- Slow digestion
- Reduce stomach volume (Correct answer)
- Remove part of the intestine
Correct answer: Reduce stomach volume
Sleeve gastrectomy involves surgically removing approximately 80% of the stomach, creating a banana-shaped "sleeve." The primary goal is to drastically reduce the stomach's capacity, which limits the amount of food a person can eat and helps them feel full sooner, leading to significant weight loss.
Question 3: Which of the following is a reversible bariatric surgery?
- Roux-en-Y gastric bypass
- Sleeve gastrectomy
- Biliopancreatic diversion
- Adjustable gastric banding (Correct answer)
Correct answer: Adjustable gastric banding
Adjustable gastric banding is considered a reversible bariatric surgery because an inflatable band is placed around the upper part of the stomach, creating a small pouch above it. The band can be tightened or loosened by injecting or removing saline, and it can be completely removed if necessary, restoring the stomach to its original size.
Question 4: What is one common complication of bariatric surgery?
- Weight gain
- Nutritional deficiencies (Correct answer)
- Increased appetite
- Enhanced digestion
Correct answer: Nutritional deficiencies
Bariatric surgeries, especially those that involve bypassing parts of the small intestine like Roux-en-Y gastric bypass, can significantly alter nutrient absorption. This often leads to deficiencies in vitamins (like B12, D, A, E, K) and minerals (like iron, calcium), requiring lifelong supplementation to prevent health complications.
Question 5: Which surgical method removes approximately 80% of the stomach?
- Gastric bypass
- Sleeve gastrectomy (Correct answer)
- Gastric band
- Biliopancreatic diversion
Correct answer: Sleeve gastrectomy
Sleeve gastrectomy is a restrictive bariatric procedure where about 80% of the stomach is surgically removed. The remaining portion is a tube-shaped "sleeve," which significantly reduces the stomach's capacity and the amount of food that can be consumed at one time, promoting satiety and weight loss.
Question 6: What is the function of the intragastric balloon?
- Blocks digestion
- Delays gastric emptying
- Occupies stomach space (Correct answer)
- Stimulates metabolism
Correct answer: Occupies stomach space
The intragastric balloon is a non-surgical, temporary weight loss device. A deflated balloon is inserted into the stomach endoscopically and then filled with saline, occupying a significant portion of the stomach's volume. This helps patients feel full with smaller amounts of food, reducing overall caloric intake.
