Gastrointestinal Diagnostics & Treatment

Question 1

Which diagnostic test is commonly used to detect abnormalities in the esophagus, stomach, and small intestine?

Accepted Answer

Upper endoscopy (EGD)

Answer

An upper endoscopy, also known as esophagogastroduodenoscopy (EGD), is a diagnostic procedure that involves inserting a thin, flexible tube with a camera down the esophagus, through the stomach, and into the beginning of the small intestine. This allows direct visualization of the upper GI tract to detect abnormalities like ulcers, inflammation, polyps, or tumors.

Question 2

Which imaging technique is most useful in detecting gallstones?

Accepted Answer

Abdominal ultrasound

Answer

An abdominal ultrasound is a non-invasive imaging technique that uses sound waves to create images of organs within the abdomen, including the gallbladder. It is highly effective and commonly used to detect gallstones, which appear as bright, reflective structures within the gallbladder, and to assess for inflammation or blockages.

Question 3

Which treatment is commonly used for Helicobacter pylori infection?

Accepted Answer

Triple therapy (antibiotics + PPI)

Answer

Triple therapy is the standard treatment for Helicobacter pylori (H. pylori) infection, which is a common cause of peptic ulcers. It typically involves a combination of two different antibiotics to eradicate the bacteria and a proton pump inhibitor (PPI) to reduce stomach acid. This regimen helps heal ulcers and prevent recurrence.

Question 4

Which procedure is used to remove polyps and detect colorectal cancer?

Accepted Answer

Colonoscopy

Answer

A colonoscopy is a medical procedure used to examine the entire length of the colon and rectum. A flexible tube with a camera is inserted into the anus, allowing direct visualization of the bowel lining. This test is crucial for detecting and removing polyps, which can be precancerous, and for screening for colorectal cancer.

Question 5

Which medication class is commonly prescribed to reduce stomach acid and treat gastroesophageal reflux disease (GERD)?

Accepted Answer

Proton pump inhibitors (PPIs)

Answer

Proton pump inhibitors (PPIs) are a class of medications that effectively reduce the production of stomach acid. They work by blocking the proton pumps in the stomach lining cells responsible for acid secretion. PPIs are widely prescribed to treat conditions like gastroesophageal reflux disease (GERD), peptic ulcers, and erosive esophagitis by reducing acid exposure and promoting healing.
