Q

clinical importance - popular question to describe walls of canal

A

potential site for most abdominal hernias (4 walls of femoral (lymphatics) and inquinal canal): male (testes outside) > female (ovaries inside)

Q

clinical signs and symptoms of hernia

A

lump/protrusion from groin, intermittently/persistently, painless/painful and uncomfortable, may be reducible or irreducible, may be strangulated with tissue death - associated with vomiting, constipation and intestinal obstruction - emergency to remove section of gut as will never recover

19
Q

conjoint tendon

A

lowest fibres of internal oblique aponeurosis and similar fibres of transversus abdominis aponeurosis join to form conjoint tendon attached medially to linea alba

20
Q

direct - acquired

A

tends to go through Hesselbach’s (inguinal) triangle which is awlays medial to inferior epigastric vessels

21
Q

indirect - congenital - slide 40

A

always an internal ring which is lateral to inferior epigastric vessels; through the canal and though upper ring?

22
Q

direct

A

older age as weaker, posterior wall of canal, chronic straining and weak masculature; hernia path straigh through posterior wall of inguinal canal

23
Q

Hasselbach’s triangle

A

3 structures: rectus abdominis muscle, inferior epigastric vessels, inguinal ligament

24
Q

indirect

A

most common, younger, indirect path, dilated deep ring, enters deep ring then passes through inguinal canal, external inguinal ring and scrotum

25
Q

femoral hernias

A

slide 47

26
Q

femoral canal borders

A

superior: inguinal ligament, inferior: pectineus fascia, medial: lacunar ligament, lateral: femoral vein

27
Q

femoral hernias on examination

A

irreducible - can’t be pushed back, hot and painful if strangulated, distinguished from inguinal as appear below and lateral to pubic tubercle (inguinal are above and medial to pubic pubic tubercle)
