inital managemnt of acute abdome
abcde approach
airway
breathing
circualtion
disability= consiousness, gluocse levels
exposure- final assemsne tand abdo examination
investigations for acute abdoem
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 us - gallstones, gyny, biliary duct dilation
ct scans
what management is tere after abcde done for acute abdomen
alert sneior
nil by mouth ncase need surgery
bg tube if bowel obstructio
iv fluids may be needed
analgesia
iv antibiotics if infection
vte assesment
prescribe regular emds
signs of periotonitis
guarding - involuntary tensig of abdo wall muscles when palpated to protect area below
rigidity= involuntary persitant tightness
rebound tenderness= rapidly releasing pressure in the abdo creates worse pain than the presure itseld
coughing test- may result in pain in abdo
percussion tenderness
casues of localised peritonitis
underlying organ inflammation- appendicitis/ cholecystitis
casues of genrealsied periotnitis
perforation of abdo organ - ruptured appendix, perforated duodenal ulcer = release contents into abdo cavity
have gernealsied and localised peritonitis and what other casue of peritonitis
spontaneous bacteral peritonitis
= spontaenous infection of ascites in liver disease
trea ith brad spectrum antibiotcs
appendix is connecte to what
caecum
how does appendititis ocur
obstruction trap pathogens in appendix= infllamtion = can lead to gangrene and rupture
if rupture faecal contents and infective material in peritonal cavity= peritonitits
central abdo pain that moved to right iliac fossa in 12 hrs
appendicitis
rovsings sign can mean what
appendicitis
= press on left iliac fossa and get pain in right iliac fossa
s and s of appendicits
age of presentation
10-20 yrs old most common
can be in any age
less common over 50
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
rebound tenderness in RIF
percussion tenderness
bottom two suggestive of peritonitis= ruptured appendix
what sings that appendix has ruptured
rebound tenderness
percsussion tenderness= peritonitits
how to diagnsoe appendicitis
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
whats an appendix mass
on examination feel mass in rif
usually longer duration of onset
due to omentum sticking to inflammed appendix
treat appendix mass
antibtiocs and supportive treatment then appendicectomy once acute condition resolved
management of appendicitis
admission to hosp
10yrs over usually seen by adult general surgeon
appendicectomy - laparascopic decreased risks and faster recovery than laparotomy
complications of appendicectomy
bleeding, scar, pain , infection
scar
damage bowel, bladder and other organs
remove of normal appendix
anesthesia risks
VTE- pe and dvt
whats more common bowel obstruction - large or small
small bowel obstruction more common than large
whats the pathology of bowel obstruction
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
casues of bowel obstruction
hernia - small bowel
adhesion - small bowel
tumours - large bowel
others:
volvulus
diverticular disease
strictures- secondary to crohns
intussuscpetion- 6months - 2year olds
when taking history and thinking bowel obstruction what need to ask about
casues of bowel obstruction - so hernia, recent operation, bowel habit, weight loss, bleeding
what casues adhesions in bowel
adhesions= scar tissue thaa binds the abdo contents together so kink and sqeeze bowel
endometriosis
peritonitits
abdo/pelvic surgery- esp open surgery
abdo/pelvic infections- pelvic inflammatroy disease
can be congentiatal or secndary to radiotherpay
whats a closed loop obstriction
two pints of obstructio so middle section of bowel sandwhiched= no way to drain out and no way to decompress so keeps expanding and will cause ischemia and perforation
causes of closed loop obsutrcion
adhesions - that compress two areas of the bowel
hernias= that isolate a section of bowel blocking wither end
volvulus= twists section o intestine
single point of obstruction in large bowel with a compenent ileocaecal valve= so contents cant flow backwards
presentation of bowel obstruction
vomiting- esp green billious fluid
absolute constipation and no flatulence
abdo distention
diffuse abdo pain
tinkling bowel sounds may be heard early on
what see in abdo xray in bowel obstruction
diameter of normal upper limit of small, colon and caecum
distention of bowel loops
normal upper limits of diameter of bowel:
3cm cmall bowel
6cm colon
9 cm caecum
how to know its large or small bowel on abdo xray
valvulae connvientes = small bowel. mucosal folds go all around width
haurasistra= large bowel- dont go all across
initial management of bowel obstruction
abcde
bloods- u and e to see elctroylte imbalance
vbg= raised lactate due to ischemia and metbaolic alklalosis due to vomiting stomach acid
nil by mouth
iv fluids - electroyle balance and hydration
ng tube with free drainage
abdo xray
what investigations do bowel ostruction
bloods
abdo xray - initial imaging
erect cxr to see if air uder diapraghm= perforation
contrast abdo ct= need check u and e frst and have cannula in to check renal fucntion cus using contrast
what investigation is inital and what is for confirming diagnosis of bowel obstruction
inital= abdo xray
confrim diagnosis= contrast ct - remeber to check u and e for renal fucntion
wehn will urgent intervention be needed in bowel obsturction
haemodynamically unstable =
sepsis
bowel perforation
bowel ischemia
hypovolaemic shcok- due to thrid spacing
when do surgery for bowel obstriction
can do watch and wait conservcative if stable to see if reoslvoes.
surgery for exploraition, hernia repair, adhesiolysis, stent via colonsocpy if tumour blockijng way
whats ileus
peristalsis of small bowel temporaily stops
whats pseudo obstruction
large bowel
no mechanical cuse of obstruction = functional obstruction of bowel
casues of ileus
surgery of abdomen- handling intestine
injury to bowel
infection/inflammation of bowel or nearby:
appendicitits, pancreatitis, peritonitits, pneumonia
distended abdomen
absolute constipation and no flatulence
diffuse abdo pain
no bowel sounds
vomiting green bilious stuff
ileus
same as bowel obstruction but no bowel sounds wereas mechanical obstruction may hear tinkling osunds on early obstruction esp
management ileus
normally resolves by treating uderlying cause
supportive treatment
iv fluid - electrolyte balance and hydration
ng tube if vomiting
nil by mouth
mobilisation- stimulate peristalsis
TPN= total parenteral nutrition may be required whilst waiting for bowel to regain function
whats the two types of volvulus
sigmoid
caecum
causes closed loop obstruction
whats more common volvulus
sigmoid
when does signoid and caecal volvulus occur
sigmoid- older pts
chronic constipation and lenghtehtning of the mesentery attactehced to sigmoid colon - sigmoid colon becomes over loaded with faces and sinks downwards and twists
caecal- younger pts
risk facotrs for volvulus
chronic constipation
high fibre diet
neuropsychiatric disorders - parkinsons
nursing hoe residents
pregnacy
adhesion
over use of laxatives- sigmoid
presentation of volvulus
like bowel obstruction- cus it is its a closed loop obstruction
abdo distention
diffuse abdo pain
absolute constipation and no flatulence
vomiting- esp green bilious vomiting
diagnose volvulus
contrast CT = investigation choice to confri daignsois/ idnetify other pathology
can do abdo xray
abdo xray shows coffee bean sign in bowel
what is this
sigmoid volvulus
mangemnt of volvulus
inital- same obstruction
iv fluids, ng tube, nil by mouth
conserevative=
endoscopic decompression in sigmoid volvuus if no peritonitits - uses felxi sigmoidoscopy
surgical:
lapartomy
hartmanns procedure = sigmoid = remove rectosigmoid and make colostomy
ileocaecal resection or a right hemicolectomy in caecal volvusus
risk factors for bowel cancer
fam hist
FAP
HNPCC
IBD
low fibre high red mean and processed diet
obestiy and sedentary lifestyle
smoking
alcohol
whats FAP
familial adenomatous polyposis
autosomal domintant
polyps form in large bowel that can be cancerous
malfunction in tummour supressor gene = adenomatous polyposis coli -APC
treat- remove all large bowel to be prophylactiss
whats HNPCC
herediatry non polyposis colorectal cancer - lynch syndrome
autsomal dominant
mutation in dna mismact hrepair gene
increase risk of lots cancers
doesnt casue mulitple adenomas
when refer for 2ww for bowel cacner
over 40 and got unexplained weight loss and abdo pain
over 50 and got unexplained rectal bleeding
over 60 and got change bowel habit/ iron deficicey anemia
whats iron deficency anemia results
microcytic anemia with low ferritin levels
presentation bowel acner red flags
weight loss
unexpaliend abdo pain
change bowel habits- normally diarrhoea and increase frequency
rectal bleeding
iron deficicney aneamia
abdo/rectal mass
acturely present with obstruction
what to do for screening bowel cacner
FIT test
what to do for daignosis of bowel cancer
goldstanderad is colonoscopy with biopsy
what investigations do for bowel cacner
fit test- human hb in stool
can be used screening 60-74 every 2 years
can be used for pts who dont fit 2ww eg. under 60 with change bowel habit
colonoscopy woth biopsy - gold standerd for diangosis
felxi sigmoidoscopy = if only got rectal bleeding
ct colography- bowel prep and contrast - do if pt not fit for colonscopy
staging ct scan- thorax, abdo ,pelvis
carcinoembryonic antigen - tumour marker for bowel cancer = used to predict relaspe in pts who have had previous bowel cancer
managemnt of bowel cancer
chemo
radiotherpay
palliative
surgery- can be cure or palliative
whats right hemicolectomy
removeal of caecum, ascending and proximal transverse colon
left hemicolectomy
remove distal transverse colon and descinging colon
high anterior resection
remove signoid colon
low anterior resection
remove signoid colon, upper rectum but spare lower rectum and anus = anastamose between colon and rectum
abdomino perineal resection
remove rectum and anus and maybe sigmoid colon
hartmanns procedure
in emergency done
remove recto sigmoid colon and create colostomy. suture recostump closed
can be rversed
pt had surgyer for bowel cancer but not got increased urgencyand frequency
diff to cotrol flatulence
faecal inconitnence
lower anterior resection syndroe
complication bowel surgery
bleeding, pain, infection
dmaage to n, bv, bladder, bowel, ureter
post op ileus
anesthetic risks
laparscopic but then had be open
leakage/failure of anastamoses
need stoma
copuldnt remove tumour
intrabdo adhesions
change bowel habit
VTE
incisional hernia
follow up bowel cancer surgery etc what test to do
CEA- carcinoembryonic antigen
ct thorax,abo and pelvis
fore gut/ blood supply to foregut
coeliac artery
stomach,part duodenum, pancreas, spleen, biliary system
midgut and blood supply to it
superior mesenteric artery
distal part duodenum–> first half transverse colon
hingut and its blood supply
inferior mesenteric artery
second half trasnverse colon–> rectim
whats chronic mesenteric ischemia
like angina
narrowing of mesenteric arteries due to atherlosclerosis
intermittent abdo pain when the blood supply cant keep up with demand
central colicky abdo pain after eating - start 30 mins after eating, least 1-2hrs
abdominal bruit on auscultation abdo aorta
weight loss- cu dont want eat cus hurt
what is this
chronic mesenteric ischemia
risk factors chronic mesenteric ischemia
same as cvd
hypertension
diabetes
raised cholesterol
smoking
fam hist
inreased age
diangose chronic mesenteric ischemia
ct angiography
magement chronic mesenteric ischemia
secondary prevention= statin, antiplatlet meds
reduce modifiable rf
revascularisation - first line endovascular procedure = percutaneous mesenteric artery stening
or open surgery - endartectomy, reimplantation and bypass graft
pt has acute non specific abdo pain but the pain is v severe but not really any findings on examination
acute mesenteric ischemia
what is and the cause of acute mesenteric ischemia
typically a rapid blockage in blood flow of through the superior mesenteric artery usually due to thrombus
thrombus due to either forme din the bv or embolsism
risk factors of acute mesenteric ischemia
