According to the Bismuth-Corlette classification system, perihilar cholangiocarcinomas extending into the right secondary intrahepatic ducts are classified as:
A. Type IV
B. Type IIIa
C. Type IIIb
D. Type I

B. Type Illa
Rationale:
The Bismuth-Corlette classification is used to describe perihilar (Klatskin) cholangiocarcinomas based on how far the tumor extends into the biliary tree:
* Type I: Below the confluence of the right and left hepatic ducts
* Type II: Involves the hepatic duct confluence
* Type Illa: Extends into right secondary intrahepatic ducts
* Type Illb: Extends into left secondary intrahepatic ducts
* Type IV: Involves both right and left second-order ducts (multifocal)
High-Yield Point:
Type Illa involves extension into the right biliary tree, impacting surgical resectability and planning.

At what week of human embryonic development does the appendix appear as an outpouching from the caudal limb of the midgut?
A. 4th week
B. 8th week
C. 5th week
D. 6th week

B. 8th week

Rationale:
The appendix develops as a diverticulum from the caudal limb of the midgut loop during the 8th week of embryonic life. Initially, it appears as a small bud from the cecum, which itself develops earlier (around the 6th week). The appendix elongates as the cecum grows, and its final position varies due to differential growth and rotation of the gut.

High-Yield Point:
The 8th week is a critical period for the formation of many GI tract derivatives, including the appendix.

What is the only vascularized suspensory ligament of the spleen?
A. Gastrosplenic ligament
B. Splenorenal ligament
C. Phrenosplenic ligament
D. Splenocolic ligament

B. Splenorenal ligament

✅ Rationale (Based on Your Document):
From the [Spleen lecture document], the spleen is held in place by several suspensory ligaments, but only one is vascularized:

🌟 Splenorenal ligament:
🔹 Connects spleen to the posterior abdominal wall (near left kidney)
🔹 Contains the splenic artery and vein
🔹 Only ligament carrying vascular supply to the spleen.

📌 Other Ligaments (Non-vascularized):
A. Gastrosplenic ligament
🔸 Connects spleen to stomach
🔸 Contains short gastric vessels, but not the main splenic vessels

C. Phrenosplenic ligament
🔸 Connects diaphragm to spleen
🔸 Non-vascularized

D. Splenocolic ligament
🔸 Connects spleen to colon
🔸 Non-vascularized

The following statements are true EXCEPT: A. Common benign liver lesions can often be reliably diagnosed via imaging B. Ultrasonography is the mainstay for liver imaging C. Acute variceal bleeding is managed with resuscitation and endoscopy D. All are true

Acute cholecystitis is considered: A. A primary infectious process with secondary inflammation B. A primary autoimmune process C. A sterile primary inflammatory process D. A primary inflammatory process with occasional bacterial contamination

G cells are mainly located in which area? A. Pylorus B. GE junction C. 2nd part of the duodenum D. Antrum

D. Antrum Rationale: G cells, which secrete gastrin, are primarily located in the gastric antrum. Gastrin stimulates acid secretion by parietal cells and promotes mucosal growth. Some G cells may also be found in the duodenum, but the antrum is the main site. High-Yield Point: G cells = Antrum → Gastrin → Parietal cell stimulation → HCl secretion

The solubility of cholesterol in bile is determined by: A. Cholesterol, bile salts, lecithin B. Calcium, cholesterol, bile salts C. Bile salts, cholesterol, bilirubin D. Cholesterol, calcium, bilirubin

A. Cholesterol, bile salts, lecithin Rationale: Cholesterol solubility in bile is determined by the ratio of cholesterol to bile salts and lecithin (a phospholipid). When this balance is disturbed (e.g., increased cholesterol or decreased bile salts/lecithin), bile becomes supersaturated, predisposing to cholesterol gallstone formation. High-Yield Point: Cholesterol solubility = cholesterol : bile salts : lecithin ratio — imbalance leads to gallstone risk.
