Editing Colon and rectum (section)

=== '''Transverse colon''' ===

*** Approximately 45cm in length
*** Suspended between the hepatic and splenic flexures, which are fixed structures
*** Completely covered by visceral peritoneum
*** Connected to the posterior abdominal wall by the transverse mesocolon - made up of four layers (same as greater omentum)
*** Can be dissected free of greater omentum with relatively little bleeding due to embryonic tissue planes - if getting bleeding, likely in transverse mesocolon - easiest to establish correct plane at either flexure and work medially
*** 'U' shape in coronal plane which can extend as far inferiorly as the pelvis in some patients
*** Blood supply from middle colic artery
***
