Right and left crus

Medial arcuate ligament (psoatic arcade)

Lateral arcuate ligament (over quadratus lumborum) Phrenic nerve – C4 Lumbocostal and sternocostal triangle

Diaphragmatic surface of the heart Phrenic nerve C4, directly above forelimb limbbud… then differential growth of neck… Mouse embryo stained for neurofilaments (=axons) and Sonic Hedgehog (notochord and endoderm) Craniocaudal direction of development.

Sacral parasymp. Red=autofluorescence of blood in the heart.

Descent and initial innervation of developing diaphragm.

Greer J J et al. J Appl Physiol 1999;86:779-786

Development of the diaphragm 3-layered embryonic disc ‚folding ‘ or rather relative differential growth of the embryo around the umbilicus Descent - relative growth of neck and heart towards the umbilicus Transverse septum - central tendon beneath the heart pleuroperitoneal folds add from dorsal and lateral aspects (these were inhabited by myogenic cells from cervical somites C4) in final caudal position, the material of internal thoracic wall will join (plus material around oesophagus)

Defects - diaphragmatic hernias (do not mix with hiatus hernia) not covered by hernial sac (false hernia) prevalence 1:3000, mortality 25% 80 % of all congenital lung anomalies 95 % on left (Bochdalek’s hernia – lumbosacral) 5 % on right (Morgagni hernia – sternocostal)

Correlation between the extent of phrenic nerve intramuscular branching and myotube formation.

Midline laparotomy upper lower

Pfanenstiel (bladder, Caesarian)

Laparoscopic operation Veress needle capnoperitoneum - CO2 Space for manouvre CO2 gets absorbed in embolisation and mainly - does not burn

Complications Damage of epigastric blood vessels, and gut Puncture of aorta = can be lethal Equipment for laparoscopic surgery

Advantages of laparoscopy

Early Less pain, faster healing, collaboration in rehabilitaton

Long-term Preserves integrity of abdominal wall, less scarring, adhesions, hernias in scar Robotic surgery
