Peritoneum is continuous, glistening (glitzernd) and slippery transparent Parietal Peritoneum is SENSITIVE and semipermeable Visceral Peritoneum is stimulated by stretching and chemical irritation Intraperitoneal does NOT mean inside peritoneal cavity o Means (almost) completely covered with peritoneum Extraperitoneal, Retroperitoneal, subperitoneal only Partially covered Ligaments o Splenorenal Ligament/Lienorenal Ligament o Gastrophrenic ligament (Greater Omentum) o Gastrosplenic ligament (Greater Omentum) o Gastrocolic ligament (Greater Omentum) Consequences of convolution; o o Fields (fusion fascia)  Oval, Triangular and Quadriangular Space  Oval field covers most of Duodenum and Pancreas  Triangular field (Right Infracolic Space)  Ant. Wall is greater Omentum  Content Jejunum Ileum  Right border is ascending colon  Sup. Border is right part of transverse mesocolon  Left border is the Mesentery (of small intestine)  Quadrangular Field (left infracolic space)  Post. Is fusion fascia(quadriangular field)  Left border is transverse colon  Inferior is Sigmoid colon  Right border is the The Mesentary or the imaginary Midline (depends on literature)  Superior Transverse Mesocolon  Content Jejunum or Ileum  Oval field (Supracolic space)  Left border is dorsal Mesogastrium  Medial border is imaginary Midline (is the original insertion of all Mesentary)  Content: Its empty, the Omental Bursa (which Ant. Walls are Stomach and Lesser Omentum)  Anterior Border o Compartments o Recesses  Duodenal Fossa at Duodenojejunal flexure  Superior Duodenal Recess  Inferior Duodenal Recess  … third one  Ileocaecal superior recess  Ileocecal Inf recess  Retrocecal resess o Folds  Reflectons of Peritoneum raised from the body wall by underlying blood vessels, ducts and ligaments of bliterated fetal vessels  Functions of Mesentery

o Holds organs in place o Site of fat storage o Provide route for vessels and nerves Ventral Mesentery derivates o Lesser Omentum o Falciform Ligament Dorsal mesentery o Greater Omentum, Transverse mesocolon, mesentery, sigmoid mesocolon, mesoappendix Parietal Peritoenum can be Primary or Secondary (FUSION FASCIA) Omental Bursa o Borders  Hepatoduodenal Ligament and Hepatogastric Ligament Anteriorly  Parietal Peritoneum with Inf. Vena cava and Aorta o Which recess can we see in Sagittal Plane?  Superior and Inferior Recess  Splenic recess requires transverse section o Omental Antrum o Superior and Inferior Recess o Splenic Recess on the left site!  Made by Splenorenal and Gastrosplenic ligament o 4 ways to enter Omental Bursa  Omental Foramen of course  If you cut greater Omentum  If you cut transverse mesocolon  Rupture lesser omentum # o Omental Foramen  Between Portal vein and (Retroperitoneal) Inf. Vena Cava  Splenic Vein enters Spleen through Splenorenal ligament Greater Sac o Supracolic Comaprtment  R/L supraphrenic recess  Is divided by Falciform Ligament  Subhepatic recess  Perisplenic Space o Infracolic compartment  Right Infracolic Compartment  Left Infracolic Compartment  R/L Paracolic gutter o...
