Q

investigations for acute abdoem

A

fbc= low hb? show bleed, wbc= inflam/infection
lft- liver function
u and e= electrolyte balance and see renal fucntion if going to have conrast
inr= see liver fuction and clotting ability
crp
amylase= see if inflam of pancreas
serum ca= score for acute pancreatitis
hCG/ urine preg test= all women child bearing age
serum lactate
abg= lactate and po2
group and save
blood culture- infection

abdo xray= bowel obstruction suspected see dialted bowel loops

erect cxr= show air under diapghragm if perforated intra bdo

abdo pain thats central and moves to roght iliac foss within 24 hrs

palaptation have tenderness at mc burneys point= 1/3 from of the distance from anterior superior iliac spine to umbillicus = line can feel the anterior iliac spine- most anterior boy bit and then a thrid away from this in a line to the belly button- bascially right iliac fossa

anorexia
nasuea and vomiting
low grade fever
rovsings sign= pain on right iliac
fossa when press on left
guarding
can get loin pain or bladder irritation, iritate ureter and abdo pain. can have diarrhoea if irritation of ileum

Q

how to diagnsoe appendicitis

A

alvarado score- help with probabiliyu
daignosis done by clinical presentation and raised inflammatory mnarkers

can do ct if need confrimation of diagnsosis esp if other differentials posisble

us can be done in feemales to exclude gyny

us can be done in children instead of ct if ct radiatio inappropriate
can do diagnostic laparascopy if clincial presentation suggest appendicitis but infecstigations say other wise. if need can then do appendicectomy at same time if needed

Q

whats the pathology of bowel obstruction

A

get obstruction causing back pressure and casues vomiting and dilatation of bowel proximal to obatruction

gi tract secreted fluid tjats then reabsorbed in colon but in obstruction cant get there so less fluid reasborbed so less fluid in intravascualr sapce causing hypovolaemia and shock = called third spacing

higher up the obstriction the greater the fluid loss as less bowel to reabsrob

diverticulosis
diverticular disease
diverticulitis

A

diverticulosis= got diverticula= out puches of bowel = normally large
diverticular disease= got symptoms due to the out puches

diverticulitis= the puches got infalmmed/ infected

91
Q

why does divertular disease occur

A

theres circular muscles in the large intestine but its weak where the bv penetrate = vulnerbale
the pressure in the lumen over time causes gap to form in areas of circular muscles = mucsoa herniate

theres longitudinal muscle in large bowel= teniae coli but doesnt go all way aorund diabteter.

doesnt happen in recutm cus got longitudianl m all around

92
Q

where most commonly diverticula form

A

sigmoid colon
can get in small bowel but less common than large

93
Q

risk factors diverticular disease

inreased age
low fibre diet
use NSAIDs –> increases risk of diverticular haemorrhage
obestity

lower left abdo pain
constipation
rectal bleeding

A

diverticular disease

95
Q

investigfations and management diverticular idsease

A

ususlay incidental finidng on ct/ colonscopy dont need do anything if asymptomatic
give advice on high fibre diet and weight loss
use bulk forming laxatives if needed- ispaghula husk - dont use stimulant laxatives eg. senna
surgery to remove area

96
Q

what laxatives use in diverticualr disease

A

bulk forming laxatives = ispaghula husk

dont use stimulant laxatives eg. senna

97
Q

pain and tenderness in left iliac fossa (remeber diverticula normally where the sigmoid colon is) / left lower abdomen
fever
diarrhoea
nausea nad vomititng
rectal bleeding palpable abdo mass if absess formed
rasied crp and rasied wbc

98

can be manged priary care
oral co amoxicalv at least 5 days
no solid foods- clear liquids only until symptoms go 2-3 days
follow up within 2 days
analgesia but avoid nsaids and opidios

99

admsision
deal how deal with sepsis./ any acute badomen ( like the patient who saw on home visit who called ambulace for)
iv fluids
iv antibiotics
nil by mouth
analgesia
urgent investigfations- ct
urgent surgery if comolciations

100

perforation
peritonitits
peridiverticular disease
large haemorrhage- need transfusion
fistula- connecting colon to bladder / vagina
ileus/ obstruction

101
Q

risk factors/associations aith haemorrhoids

A

= differentials for rectal bleeding
IBD
colorectal cancer
anal fissures
diverticulosis

108
Q

managemnt of haemorrhoids

A

consider testing for anemia if got proglonged bleeding / signs of anemia

topical treatment:
for symptoamtic treatment and reduce the swelling
- anusol= chemical that shirnks them

  • anusol HC- got hydrocortisone in = short term use only
    germoloids cream = lidocaine= LA
    proctosedyl ointment = cinchocaine an dhydrocortisone = short term use only

prevention and treamtment for constipation:
- increase fibre
drink fluids
laxatives
encourage to not strain

non surgical=
rubber band ligation
injection slcerotherpay = slcerosisi and atrophy
infra red coagualtion= dmaage blood supply
bipolar diathermy = electric current

surgical:
haemorrhoid artery ligation haemorrhoidectomy = removing anal cusion and s can get faecal incontinece
stapled hamorrhoiectomy

109

colostomy = colon brought to skin- more solid stools- flatter to the skin as sold contents less irriatating to skin
typically left iliac fossa but can be anywhere

ileostomy = ileum brought to skin
liquid stools
have a spout
typically right iliac fossa but can be anywehre

forty
fair
female
fat

122
Q

presentation of gallstones

A

biliary colic- intermittent right upper quadrant pain / epigastric
pain often triggered by eating esp high fat meals - last 30 mins -8hrs
may have N and V

may present with the complications of gallstones :
acute cholecystitis, acute cholagntitis, pacnreatitis, obstructive jaundice

123
Q

what triggers the bilairy colic in gallstones

A

when fat enters digestive system the duodenum secretes CCK which triggers cotraction of gallbladder - stone in their obstrcuting flow so get colic
pts should avoid fatty meals to prevent cck release and gallbladder contraction

124
Q

with gallstones what will the liver function tests show

A

raised billirubin = pale stools and dark urine = obstrucive picture

raised ALP

ALT AND AST can be raised but not as much proprtion of alp

thickened gallbladder wall, stones/sludge in gallbladder nad. fluid around gallbaldder

130
Q

what other investigations for gall bladder apart from forst line US

A

MRCP- snesitive to view bilaiory tree in detail
used if us doesnt show scans but theres bile duct dilatation / raised billirubin suggesting obstruction

ERCP
- endocpe doen

indication to do ERCP is to celar stones from bile duct
can inject contrast and take x ray to visualise biliary system
can perfrom sphincterotomy on the sphincte rof Oddi if its dysfucntional
clear stones from duct
insert stents
take biopsy

damage to bowel , bv, other organs
anestheitc risk

VTE
post cholecystectomy syndrome

134
Q

whats post cholecystectomy syndrome

occur after cholecystectomy
may be due to changes in bile flow
symptoms s improve with time

diarrhoea
indigestion
epigastric/RUQ pain / discomfort
nasuea
intolerenac eof fatty foods
flatulence

135
Q

whats the casues of acute cholecystits

A

mainly are due to gallstone trapped in neck of gallbladder or in cystic duct = calculous cholecystitis

few cases the gallbladder cant empty for other reasons = acalculous cholecystitis

eg. if pt in icu and not eaten / period of starving then the gallbladder nmot beig stimulatedby food to regulary emoty results in build up of presure

Q

lateral and inferior to pubic tubercle lump

A

femoral hernia

201
Q

whats the most common casue of small bowel obsstruction

adhesions
if pt had abdo surgery eg. appenciectomy always then think could be casuing small bowel obstrution - esp if got constipation, distention and early vomit

202
Q

treatment samll bowel obstruction

A

drip and suck
iv fluids with added potassium=> the proximal part of the bowel to the occluded bit will undergo more peristaliss (trying to move stuff) and so bowel will secrete more electroyltes including potassium which dont want to go hypo cus heart
ng tube

203
Q

most specific gold standard test for acute pancreatitis

hyponatreamia

207
Q

A 46-year-old man presents to the emergency department complaining of 3 days of watery diarrhoea which is occasionally bloody. On further questioning, he reveals cramping abdominal pain over the same period. He has dry mucous membranes and a prolonged capillary refill. Five days ago, he was started on a new medication by his GP.

What medication is most likely to cause this presentation?

A

climdamycin - can casue c diff

208
Q

fever, jaundice and right upper quadrant pain

A

ascending cholangiis

209
Q

richters hernia

A

Richter’s hernia is characterised by the absence of symptoms of obstruction even in the presence of strangulation, as the bowel lumen is patent while bowel wall is compromised. The VBG shows a low pH (acidotic) with a low pCO2 (due to partial respiratory compensation) and low bicarbonate (suggesting the cause of acidosis is metabolic) - metabolic acidosis which can occur due to the build-up of lactate.

210
Q

biliary colic

A

gallstones in way
when eat heavy meal esp if fatty the gallbladder contracts to put bile into intestne and this then means bile trying to get past the stone and so pushing it so comes in waves the pain and last 1-2 hrs not long
ruq pain

211
Q

A 37-year-old attends surgery due to a one day history of severe central abdominal pain radiating through to the back. He has vomited several times and is guarding on examination. Parotitis and spider naevi are also noted.

A

acute pancreatitis
spider naevi and parotitis suggest high alchol intake

212
Q

drugs causing pancreatitis

A

azathioprine, mesalazine*, didanosine, bendroflumethiazide, furosemide, pentamidine, steroids, sodium valproate

213
Q

treatment of un ruptured sigmoid volvulus

A

Sigmoid volvulus is a common pathology in the elderly which can initially be managed non-operatively with flatus tube decompression, avoiding the need for surgery which is higher risk in this age group. Decompression this way usually results in resolution of the volvulus without recurrence. Second line treatment is insertion of a percutaneous colostomy tube to decompress the volvulus when flatus tube decompression has proven unsuccessful or recurrence has occurred despite multiple attempts.
