small bowel Flashcards
INGUINAL HERNIA direct vs indirect
- direct(1/3) = bowel enters inguinal canal ‘directly’ through a weakness in hesselbachs triangle (??) and lies medial to inferior epigastrium vessels
- indirect (2/3) = bowel enters inguinal canal via deep inguinal ring and lies lateral to inferior epigastrium vessels
INGUINAL HERNIA risk fax?
- male
- inc age
- raised intra abdo pressure eg? x3
- obesity
INGUINAL HERNIA clinical features ?
presenting sx: lump in groin - disappears initially (reducible) w minimal pressure or when pt lay down. mild discomfort w activity or standing
- hernia becomes incarcerated ??? painful, tender, erythmatous. may also present w sx of bowel ob or strangulation (irreducible & tender lump w pain out of proportion to clinical signs ) if blood supply compromised
INGUINAL HERNIA OE?
look for:
- cough impulse - -ve if irreducible
- location - supermedial to pubic tubercle
- reducibility - on lying down +/- minimal pressure
- if it enters the scrotum - can u get above it? is it separate from testis?
INGUINAL HERNIA differentials
femoral hernia, saphena varix, lipoma, groin abscess
extends in groin ? hydrocoele, varicocoele, testicular ca
INGUINAL HERNIA investigations?
dx clinical
only image if dx unsure or to exclude other path - uss. features of ob or strangulation? ct
INGUINAL HERNIA mgmt - non symptomatic pt?
conservative mgmt
INGUINAL HERNIA mgmt - pt w strangulation sx?
URGENT surgical exploration
INGUINAL HERNIA mgmt - symptomatic pt (significant mass or discomfort )?
surgery
- open mesh repair - primary inguinal hernia any anaesthetic
- laparoscopic - in pts w bilateral or recurrent inguinal hernias, also considered in: primary unilateral hernia, those @ high risk of chronic pain (eg young&active, prev chronic pain, predominant sx is pain) or in females (due to inc femoral hernia risk)
INGUINAL HERNIA comps
in creation, strangulation, obstruction
post op comps: pain bruising haematoma infection urinary retention, recurrence, chronic pain, damage to vas deference or testicular vessels
FEMORAL HERNIA stats
uncommon
high risk strangulation
f>m due to wider anatomy of pelvis
FEMORAL HERNIA risk fax?
female, preganancy, raised intra abdo pressure, inc age
FEMORAL HERNIA clinical features?
- small lump in groin
- many asymptomatic
- 30 % present as obstruction or strangulation
- tight femoral ring means unlikely to be reducible
- location: inferolateral to the pubic tubercle (and medial to femoral pulse)
FEMORAL HERNIA differentials?
inguinal hernia, lipoma, lymph node, saphena varix, femoral artery aneurysm
FEMORAL HERNIA saphena varix differential more info
this is a dilation of the saphenous vein @ th saphenofemoral junction in the groin. disappears when lying flat, has a palpable thrill when coughing & therell be presence of varicose veins elsewhere. best identified by duplex us and mgmt is high saphenous ligation
