Question 2

What is Wernicke's encephalopathy and how is it related to bariatric surgery?

Accepted Answer

A neurological condition caused by thiamine (B1) deficiency, which can occur after persistent vomiting post-surgery

Answer

Wernicke's encephalopathy is caused by thiamine deficiency and can develop rapidly in bariatric patients with persistent vomiting who are not supplementing.

Question 3

What is 'band slippage' in adjustable gastric banding and what are its symptoms?

Accepted Answer

The stomach slips upward through the band creating an enlarged upper pouch, causing vomiting and reflux

Answer

Band slippage occurs when the stomach migrates upward through the band, creating an enlarged pouch, typically presenting with vomiting and GERD.

Question 4

Which lab finding is a red flag for serious nutritional complications in a bariatric patient presenting with fatigue and pallor?

Accepted Answer

Low hemoglobin with microcytic or macrocytic anemia

Answer

Anemia in bariatric patients may be microcytic (iron deficiency) or macrocytic (B12/folate deficiency) and requires prompt evaluation and supplementation.

Question 5

What is 'band erosion' (intragastric band migration) and how is it typically treated?

Accepted Answer

The band gradually erodes through the stomach wall into the gastric lumen, requiring endoscopic or surgical removal

Answer

Band erosion occurs when the silicone band slowly migrates through the stomach wall; once inside the stomach, it must be removed endoscopically or surgically.
