Q

WTF is hepatorenal syndrome

A

Portal HTN causing renal failure Portal hypertension —> increased shear stress in splanchnics –> vasodilators released –> reduced renal perfusion –> RAAS system activation –> this isn’t enough to overcome the splanchnic vasodilation + persistent underiflling of these vessels –> renal failure

Anatomical location of inguinal vs femoral hernia
Inguinal hernia: **above** inguinal ligament Femoral hernia: **below** inguinal ligament /////////////////////////////// In, Above
26
Location of the deep inguinal ring
mid point of the inguinal ligament
27
O/E, how can u differentiate between direct + indirect inguinal hernia
Place fingers over the deep ring (mid pt of the inguinal ligament) If hernia is 'controlled' = indirect hernia If not = Direct ///////////////////////// Indirect goes through Deep ring. Direct Doesn't go Through Deep Ring (Deep ring is a Detour. Not done by Direct inguinal hernia) Direct doesn't do the Deep ring.
28
Where is the femoral canal
Medial to the femoral vein, behind the inguinal ligament
29
Where is the femoral pulse
Mid inguinal point (btw ASIS + pubic symphysis)
30

33
What complication must you mention to a patient undergoing inguinal hernia repair
Risk of testicular damage Ischemic orchitis from thrombosis in pampniform plexus (this is in the spermatic cord)
34
Femoral hernia - risk of strangulation? Mx?
50% risk of strangulation in 1 month! Lockwood(elective) or McEvedy (urgent = high approach to allow visualtion and resection of non-viable bowel)
35
Hydrocele - definition?causes? Ix?
Accumulation of fluid within the tunica vaginalis Causes: primary (patent proc vaginalis) secondary = tumour, epididymo-orchitis, trauma Ix: MUST do an USS to exclude malignancy
36
which side is varicocele more common? why?
LEFT is more common Left testicular vein is more vertical than right Left testicular vein is LONGER - more likely compressed by colon - sudden onset --\> think L renal cell carcinoma!!!
37
Key Qs in the examination of a scrotal lump
1. Get above it? (no = inguinal hernia) 2. Feels separate from testis? (yes = varicocele, epididymal cyst. no = tumour, hydrocele) 3. Transilluminable? (hydrocele, epididymal cyst)

Future potential of an ileal pouch anal anastamosis
50
Indications for loop ileostomy?

51
End ileostomy - what must you check and why?
Is there an anus? No anus --\> panproctocolectomy therefore permanent ileostomy
52
2 diseases which are indications for formation of end colostomy? which procedures?
CRC + diverticulitis Either following: AP resection (no anus) or Hartmann's
53
Complications of a stoma

54
AP resection vs anterior resection of a rectal tumour
anterior resection = can be performed if cancer is \>4cm from anal verge
55
Why is there no way an end colostomy would be formed after an anterior resection
Anterior resection = removal of upper rectum + sigmoid. lower rectum and desc colon are anastomosed. The anastomosis would need to be rested via a loop ileostomy
56
Diverticular disease vs diverticulosis vs diverticulitis
