Advanced Splenorenal Ligament Quiz

Q1. Why is the pancreatic tail at risk during splenectomy when the splenorenal ligament is divided?

• The pancreatic duct enters the left kidney
• The pancreatic head is fused to the splenic capsule
• The pancreatic tail lies within the operative plane near the splenic hilum
• The uncinate process lies inside the ligament

Q2. What postoperative complication can follow unrecognized pancreatic tail injury during splenorenal ligament dissection?

• Biliary obstruction from cystic duct injury
• Pancreatic fistula from pancreatic secretion leakage
• Urethral stricture
• Aortic coarctation

Q3. Why can control of the splenic vessels within the splenorenal ligament affect splenic perfusion immediately?

• The ligament contains only capillaries
• The spleen is supplied entirely by the inferior mesenteric artery
• The ligament contains the principal splenic vascular pedicle
• The splenic artery travels only in the falciform ligament

Q4. How do the gastrosplenic and splenorenal ligaments together relate to the lesser sac?

• They separate the two pleural cavities
• They form the right border of the epiploic foramen alone
• They form the pelvic floor
• They contribute to the left boundary of the lesser sac

Q5. Why must the splenic vein be handled carefully when separating the pancreatic tail from the splenorenal ligament?

• It runs within the stomach lumen
• It carries pancreatic juice
• It is closely applied to the pancreas and receives pancreatic tributaries
• It is isolated from the pancreas by the diaphragm

Q6. Which embryologic fact explains why the spleen has peritoneal ligaments derived from the dorsal mesogastrium?

• The spleen develops from pancreatic endoderm
• The spleen develops in the ventral mesogastrium beside the gallbladder
• The spleen develops from the mesonephric duct
• The spleen develops within the dorsal mesogastrium

Q7. Why can distal pancreatectomy and splenic surgery require management of the same ligamentous plane?

• The common bile duct crosses the splenic hilum
• The pancreatic tail and splenic vascular pedicle share the splenorenal ligament
• The pancreatic head and portal triad lie in the ligament
• The uncinate process forms the splenic capsule

Q8. What anatomical relationship makes the splenorenal ligament a key landmark during spleen-preserving distal pancreatic surgery?

• The ligament contains the common hepatic duct
• The ligament contains the superior mesenteric vessels and pancreatic head
• Splenic vessels and pancreatic tail lie together within the ligament
• The ligament is entirely avascular

Q9. Why may traction on the splenorenal ligament transmit force directly to the splenic hilum?

• It attaches only to the diaphragmatic dome
• It terminates in the pelvis
• It is separated from the spleen by the stomach
• Its attachment and vascular contents converge at the splenic hilum

Q10. Which statement best integrates the anatomy of the splenorenal ligament?

• It is an avascular fascial plane connecting the spleen to the bladder
• It is a ventral-mesogastrium-derived fold containing the portal triad
• It is a dorsal-mesogastrium-derived peritoneal fold containing the splenic vascular pedicle and pancreatic tail
• It is a pleural fold containing the left phrenic nerve
