    A patient comes to the emergency department complaining of a sharp pain to his right hypochondriac/epigastric area. The patient states that the sharp pain started earlier that day after he ate lunch at KFC, but that he has been experiencing intermittent pains in the same location for a few weeks. He also states that he is feeling pain over his right shoulder and into his back. The source of the patient's pain is most likely due to:

    • An inflamed appendix.

    • A ruptured appendix

    • An inflamed gallbladder

    • Peptic ulcer

    Correct Answer
    A. An inflamed gallbladder
    Explanation
    Gallbladder can also send pain impulses via the right Phrenic nerve, resulting in pain in the C3-5 dermatome, hence the pain over the right shoulder.

    While presenting a case to your attending, your colleague says that his patient has a direct inguinal hernia. You know that this hernia must be:

    • Lateral to the inferior epigastric v.

    • Medial to the inferior epigastric a.

    • Protrude through the deep inguinal ring

    • Covered by internal spermatic fascia

    • Lateral to the pubic tubercle

    Correct Answer
    A. Medial to the inferior epigastric a.
    Explanation
    direct inguinal hernia means it comes through Hesselbach’s triangle which is bounded by the lateral umbilical fold (inferior epigastric artery), linea semilunaris, and the inguinal ligament.

    While studying in the anatomy lab for an upcoming practical exam, a nosey TA approaches you, points to a structure branching off the abdominal aorta at the level of T12, and asks you to name the 3 arteries that directly originate from it. You correctly respond by saying the following:

    • SMA, Splenic Artery, and the Superior Pancreaticoduodenal Artery

    • Left Gastric Artery, Splenic Artery, and the Proper Hepatic Artery

    • SMA, IMA, and Splenic Artery

    • Left Gastric Artery, Splenic Artery, and the Common Hepatic Artery

    Correct Answer
    A. Left Gastric Artery, Splenic Artery, and the Common Hepatic Artery
    Explanation
    The artery that this TA is pointing to is the Celiac Trunk (the 3 divisions of the trunk are classic and important to remember for examination purposes). The Celiac trunk originates from the abdominal aorta at the level of T12 (the verterbral levels that the Celiac Trunk, the SMA, and the IMA originate are approximately T12, L1, and L3 respectively and are high yield relations). The Celiac trunk branches into the Left Gastric Artery, the Common Hepatic Artery (gives rise to the Gastroduodenal Artery which is at high risk for erosion during duodenal ulcers), and the Splenic Artery. Answer B is wrong because the Proper Hepatic Artery originates from the Common Hepatic Artery and not directly from the celiac trunk.

    Your 2-year old patient has had bouts of "tummy pain" and according to the mother, his diapers have had stool that looked like red currant jelly. Upon examination you find the two year old with his legs drawn up to his chest and a palpable sausage-like mass in the lower right abdomen. What is the likely cause of this child's condition?

    • Meckel's diverticulitis

    • Acute appendicitis

    • Ileocecal intususception

    • Perianal abscess

    • Pyloric stenosis

    Correct Answer
    A. Ileocecal intususception
    Explanation
    This is the classical presentation when the distal ileum telescopes into the cecum. It’s most common in children less than 2 years old (80%) and rare in older children and adults.

    A 45 year-old obese male, with a 30 pack-year history of smoking, is referred to the gastroenterologist complaining of chronic heartburn. The esophageal endoscopy image below is the result of what process? - ProProfs

    A 45 year-old obese male, with a 30 pack-year history of smoking, is referred to the gastroenterologist complaining of chronic heartburn. The esophageal endoscopy image below is the result of what process?

    • Neoplasia

    • Hyperplasia

    • Hypertrophy

    • Metaplasia

    Correct Answer
    A. Metaplasia
    Explanation
    Pictured is typical of Barrett’s esophagus, in which normal (pink) non-keratinized squamous epithelium is replaced by columnar epithelium of the intestinal type (red). Chronic gastroesophageal reflux disease (GERD) leads to Barrett’s esophagus (metaplasia), which increases the risk of adenocarcinoma (neoplasia which is preceded by dysplasia). Obesity, smoking, and alcohol are risk factors.

    Where does the transversus abdominis aponeurosis contribute to the posterior rectus sheath?

    • Superior to semilunar line

    • Inferior to semilunar line

    • Superior to arcuate line

    • Inferior to arcuate line

    Correct Answer
    A. Superior to arcuate line
    Explanation
    and inferior to the arcuate line, all aponeuroses form the anterior rectus sheath, so the posterior sheath is absent.

    • Pancreatic tail and gastric antrum

    • Spleen and gastric fundus

    • Gastric body and pancreatic tail

    Correct Answer
    A. Spleen and gastric fundus
    Explanation
    http://upload.wikimedia.org/wikipedia/commons/3/3b/Gray533.pngshort gastric arteries (off distal portion of splenic artery) supply the gastric fundus. The tail of the pancreas is also found in in the splenorenal ligament in the hilum of the spleen. Its blood supply is from the splenic artery

    Upon abdominal exam you elicit a positive Murphy's Sign for cholecystitis under the right costal margin. Assuming the gallstone is large and full of bile acids that can erode a fistulous tract through the gall bladder wall, which of the following would be the most likely culprit for a gastric outlet obstruction? - ProProfs

    Upon abdominal exam you elicit a positive Murphy's Sign for cholecystitis under the right costal margin. Assuming the gallstone is large and full of bile acids that can erode a fistulous tract through the gall bladder wall, which of the following would be the most likely culprit for a gastric outlet obstruction?

    • Cholecystocolic fistula

    • Cholecystoduodenal fistula

    • Cholecystojejunal fistula

    • Pyloric stenosis

    Correct Answer
    A. Cholecystoduodenal fistula
    Explanation
    A cholecystocolic fistula allows for emptying of the gallstone into the transverse colon and rarely will cause a gallstone ileus. The cholecystojejunal fistula and the cholecystoduodenal fistula both enter the small intestine and may block the passage by the ileocecal valve. However the question asks for a likely culprit for gastric outlet obstruction (as seen in the endoscopy photo - pylorus with gallstone obstruction). This would most likely be a fistulous tract to the 1st part of the duodenum that would occlude the lumen and outflow of pylorus (Bouveret's Syndrome). Pyloric stenosis, although being the most common cause of GOO, is not described in the stem.

    The round ligament of the liver (AKA - Ligamentum Teres Hepatis) was embryologically derived from which of the following

    • The Left Umbilical Artery

    • The Right Umbilical Artery

    • The Urachus

    • The Left Umbilical Vein

    • The Right Umbilical Vein

    Correct Answer
    A. The Left Umbilical Vein
    Explanation
    The round ligament is derived from the umbilicalvein, and more importantly theleft umbilical vein. Note: the right umbilical vein tends to regress around the second month of development, whereas the left vein persists and becomes this ligament. Also, know these embryological origins well; Median Umbilical Fold - A remnant of the Urachus and the Medial Umbilical Folds - Remnants of the Umbilical Arteries

    Years after Ned and Matt Hasselbeck’s altercation, Matt goes to see Ned about a direct inguinal hernia. What is the lateral border of Hesselbach’s triangle?

    • Median umbilical fold

    • Medial umbilical fold

    • Lateral umbilical fold

    • Lateral border of rectus abdominis

    Correct Answer
    A. Lateral umbilical fold
    Explanation
    http://upload.wikimedia.org/wikipedia/commons/a/a8/Inguinal_triangle.pngthe INGUINAL TRIANGLE is a region of the abdominal wall. It is also known by the eponym Hesselbach's triangle It is defined by the following structures • Medial border: Lateral margin of the rectus sheath, also called linea semilunaris • Superolateral border: Inferior epigastric vessels • Inferior border: Inguinal ligament, sometimes referred to as Poupart's ligament The inguinal triangle contains a depression referred to as the MEDIAL INGUINAL FOSSA, through which direct inguinal hernias protrude through the abdominal wall. The MEDIAL INGUINAL FOSSA is a depression located within the inguinal triangle on the peritoneal surface of the anterior abdominal wall between the ridges formed by the LATERAL UMBILICAL FOLD and the medial umbilical ligament, corresponding to the superficial inguinal ring.

    You were able to use ursodeoxycholic acid in time to dissolve the stone before it formed a fistula. It seemed to be beneficial over the first year after beginning treatment however one day the patient presented with pain in the epigastric area. On ultrasound you noticed an enlarged pancreas with a smaller stone in the Ampulla of Vater - obstructing the lumen of the pancreatic duct. Due to this obstruction the patient was experiencing acute pancreatitis. If the pancreas was to rupture into the abdominal cavity where would the enzymes be released.

    Mac, the surgeon, and PC, the anatomist, are fighting about which 1/2 of the liver the caudate and quadrate lobes belong to. What would Mac argue?

    • Right because they’re right of the falciform ligament

    • Right because they’re right of the IVC

    • Left because they’re left of the falciform ligament

    • Left because they’re left of the IVC

    Correct Answer
    A. Left because they’re left of the IVC
    Explanation
    http://upload.wikimedia.org/wikipedia/commons/a/a3/Gray1087-liver.pngSurgeons follow the branchings of the portal triad or hepatic veins to divide the liver into 8 segments. Instead of using the falciform ligament, surgeons draw an imaginary line between the IVC and gallbladder as the division between right and left halves.
