1. In an indirect inguinal hernia in a male, the hernia sac passes through which opening to enter the inguinal canal?
2. The lesser sac (omental bursa) communicates with the greater peritoneal cavity through which foramen?
3. A 60-year-old man presents with a bulge in the femoral triangle below and lateral to the pubic tubercle. Compared with an inguinal hernia, a femoral hernia enters the femoral canal through the femoral ring, which is bounded by all of the following EXCEPT:
4. A surgeon exploring an indirect inguinal hernia notes that the sac passes through the deep inguinal ring, traverses the inguinal canal, and exits through the superficial ring. The deep inguinal ring is located in relation to which structure?
5. A patient presents with acute pancreatitis. The enzyme-rich fluid tracks along the transverse mesocolon, creating Grey Turner's sign (flank discolouration). Through which specific peritoneal pathway does peripancreatic fluid most directly reach the flanks via the paracolic gutters?
6. Hesselbach's triangle defines the direct inguinal hernia zone. Which are its three boundaries?
7. The hepatoduodenal ligament forms the anterior boundary of the epiploic foramen (foramen of Winslow). Pringle's manoeuvre compresses this ligament to control hepatic bleeding. Which three structures run within the hepatoduodenal ligament?
8. Hesselbach's triangle defines the site for direct inguinal hernia. Which structure forms the lateral boundary of Hesselbach's triangle?
9. The hepatorenal recess (Morison's pouch) is the most dependent part of the peritoneal cavity in the supine patient. Which peritoneal reflection forms its posterior wall?
10. In a Spigelian hernia, the defect occurs at which specific anatomical location in the abdominal wall?
11. A direct inguinal hernia protrudes through Hesselbach's triangle. Which of the following structures form the boundaries of this triangle?
12. The portal vein is formed by the confluence of two vessels behind the neck of the pancreas. Which two vessels form it?
13. A 65-year-old man presents with a groin lump that descends through the femoral ring, medial to the femoral vein, and protrudes below the inguinal ligament. The neck of this femoral hernia lies in relation to which structures?
14. The hepatoduodenal ligament forms the anterior boundary of the epiploic foramen (foramen of Winslow). Which three structures run within the hepatoduodenal ligament, from right to left?
15. A patient with an indirect inguinal hernia has the sac passing through the deep inguinal ring lateral to the inferior epigastric vessels. Which structure forms the inner boundary (posteromedial wall) of the deep inguinal ring that must be carefully preserved during herniorrhaphy?
16. During a Whipple's procedure (pancreaticoduodenectomy), the surgeon must divide the uncinate process of the pancreas. Which major vessel runs in the groove between the uncinate process of the pancreas and the body of the pancreas, making this dissection hazardous?
17. The lesser sac (omental bursa) communicates with the greater sac via the epiploic foramen (of Winslow). If a pancreatic pseudocyst ruptures into the lesser sac, fluid spread is initially contained. What are the boundaries of the epiploic foramen?
18. A female patient presents with a swelling in the femoral triangle that is below and lateral to the pubic tubercle. It has an impulse on coughing. Why is femoral hernia more common in females than males?
19. During laparoscopic inguinal hernia repair (TEP/TAPP), the 'triangle of doom' is a critical vascular area the surgeon must avoid. What are the boundaries and contents of the triangle of doom?
20. The epiploic foramen (foramen of Winslow) connects the greater and lesser peritoneal sacs. Which structure forms its inferior boundary, and what is the clinical consequence of obstructing it?
21. A patient is found to have a Richter's hernia. What is the distinguishing feature of this type of hernia?
22. Hesselbach's triangle defines the region through which a direct inguinal hernia protrudes. Its boundaries are correctly described as:
23. The greater omentum is a fold of peritoneum attached to the greater curvature of the stomach and transverse colon. Its blood supply comes from which vessels?
24. In differentiating direct from indirect inguinal hernia during surgery, the most reliable landmark is the relationship of the hernial sac to which structure?
25. The lesser sac (omental bursa) communicates with the greater peritoneal cavity through which opening, and what structures form its boundaries?
26. Hasselbach's triangle is the region through which direct inguinal hernias protrude. Its boundaries are correctly described as:
27. The portal vein is formed by the union of the superior mesenteric vein and splenic vein behind which structure?
28. The epiploic foramen (foramen of Winslow) is the communication between the greater and lesser peritoneal sacs. Its posterior boundary is formed by:
29. In the inguinal canal, the deep inguinal ring is an oval opening in the transversalis fascia. The inferior epigastric vessels are an important landmark. Regarding the relationship between the deep ring and the inferior epigastric vessels:
30. The hepatoduodenal ligament forms the anterior border of the epiploic foramen (foramen of Winslow). During hepatic surgery, a Pringle manoeuvre compresses this structure to control bleeding. Which three structures does this ligament contain?
31. The deep inguinal ring is a defect in the transversalis fascia and lies lateral to the inferior epigastric vessels. Which layer of the abdominal wall forms the internal spermatic fascia as it invaginates during testicular descent?
32. The hepatoduodenal ligament (right free margin of lesser omentum) contains the portal triad. From right to left (or anterior to posterior), what is the correct arrangement of structures within the hepatoduodenal ligament?
33. The hesselbach's triangle defines the floor of the direct inguinal hernia. Its boundaries are:
34. In the retroperitoneal space, the left renal vein is longer than the right and crosses anterior to the aorta. Which vein does it receive that the right renal vein does not?
35. The deep inguinal ring is a deficiency in which structure, and what is its surface marking?
36. The hepatorenal (Morrison's) pouch is the most dependent part of the peritoneal cavity in the supine position. It communicates with the pelvic peritoneum via which route?
