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

Q

O/E, how can u differentiate between direct + indirect inguinal hernia

A

Future potential of an ileal pouch anal anastamosis

50
Q

CRC –> excision of ca + anastomosis formed –> Loop ileo diverts from healing anastomosis Crohns –> loop ileostomy provides temporary diversion from disease

51
Q

A

Is there an anus? No anus –> panproctocolectomy therefore permanent ileostomy

52
Q

A

CRC + diverticulitis Either following: AP resection (no anus) or Hartmann’s

A

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

Q

Indication for R hemicolectomy? L hemicolectomy?

A
