Q

abdominal trauma

A

can be blunt or perforating –> blunt is usually worse
often messes up liver or spleen

Concerns: shock, peritonitis, abdominal compartment syndrome (fucks with repiration and cardiac/kidney func)

Q

Treatment of peritonitis

A

-may or may not require surgery

-IV for fluid and antibiotics
-analgesia and knees flexed for pain
-rest and sedatives for anxiety

Gastroenteris

A

inflammation of stomach and small intestine
often from viruses in food

Q

IBD

A

Inflammation of GI tract with sporadic periods of remision and exacerbation –> autoimmune

2 types:
Ulcerative colitis = colon
Crohn’s disease = anywhere- mouth to anus

Treat with steroids

Q

Triggers for IBD

A

-diet, smoking, and stress which alter flora
-high sugar or fat intake
-low fruit, veggie, omega-3, or fiber
-NSAIDs, antibiotics, oral contraceptives
-genetic factors

Q

Ulcerative colitis characteristics

A

-affects mucosal layer and prevents absorption
-pseudopolyps form
-bloody diarrhea (sometimes w/ protein)
-anemia
-fever, weight loss, pain, fatigue

20
Q

Complications of IBD

A

-hemorrhage, strictures, perforation, abscess, fistula, cdif, colonic dilation
-high risk of colorectal cancer
-malabsorption, liver disease, osteoporosis
-multiple sclerosis, ankylosing spondylitits

21
Q

How to treat ulcerative colitis

A

Total proctocolectomy with ileal pouch/ anal anastomosis or permanent ileostomy

cures the issue, but is extremely mentally traumatic

22
Q

How to treat Crohn’s disease

A

surgeries to resect disease sections with reanastomosis
-often recurs
-can result in short bowel syndrome

strictureplasty - opens narrowed areas

NOT CURATIVE

23
Q

Food for IBD

A

sometimes can’t be tolerated during exacerbation
may need liquid enteral feedings
then gradually introduce foods again to determine what makes it worse

24
Q

IBD in old ppl

A

proctitis and left sided UC more common
increased risk of hospitalization and mortality
increased risk of infection and cancer
anemia, malnutrition, volume depletion
my be physically unable to get to bathroom

25
Intestinal obstruction: simple vs strangulated
simple = intact blood supply strangulated = no blood supply
26
Intestinal obstruction: mechanical vs nonmechanical
mechanical: -SBO = surgical adhesions, hernias, strictures from Crohns -LBO: colorectal cancer or diverticular disease nonmechanical: -neuromuscular parasympathetic innervation reducing peristalsis -paralytic ileus
27
pseudo intestinal obstruction
GI motility disorder -major surgery, electrolyte imbalance, neuro conditions -usually malnourished
28
vascular obstruction
emboli or thrombi alter blood supply
29
what happens to bowel when there's an obstruction
distal bowel empties and collapses proximal bowel accumulates shit, increasing pressure and capillary permeability --> fluids and electrolytes go into peritoneal cavity --> intestinal muscles get fatigues and peristalsis stops --> decreased circulating blood volume --> hypotension and hypovolemic shock
30
Interprofessional care of obstruction
emergency surgery if strangulation or perforation resection of obstructed segment with anastomosis partial or total colectomy or ileostomy for obstruction or necosis colonoscopy to remove polyps, dilate strictures, laser destruction, and remove tumors
31
Treatment of obstruction
NG tube antiemetics get cultures corticosteroids with antiemetics if malignant
32
Sessile vs pedunculated polyps
sessile = flat, broad-based, attached to wall pedunculated = attached to wall by thin stalk (bigger)
33
Genetic stuff w/ polyps
Family adenomatous polyposis (FAP) -autosomal dominant and recessive -may have thousands of polyps that'll be cancerous by 40 -hafta remove colon and rectum by age 25
34
polyps removal
need to remove all none are normal watch for bleeding post op
35
colorectal cancer
more common in men HNPCC is genetic thing --> family risk (FAP) *also obesity, smoking, alc, DM
36
growth of CRC
-start from polyp on inner lining of colon or rectum and grows -invades wall of colon or rectum, lymph nodes, and vasculature and spreads -inferior rectal vein --> portal vein --> liver --> lungs, bones, brain
37
CRC manifestations (common, early, and late) (R vs L)
don't happen til late Common = anemia, bleeding, pain, pooping issues Early: fatigue and weight loss Late: pain, palpable mass, hepatomegaly, ascites R: bleeding and diarrhea L: hematochezia and bowel obstruction
38
Diagnostic study for CRC "gold standard"
Colonoscopy -remove polyps -every 10 yrs starting at 45 -every 5 yrs starting at 40 if high risk
39
why would you do a bowel resection or ostomy surgery?
remove cancer repair perforation, fistula, or injury relieve obstruction or stricture treat abscess, iflammation, or hemorrhage
40
Risks of bowel surgeries
infection bleeding perforation anastomosis leak
41
Ostomy
hole for fecal matter to go through (temp or perm) ileostomy: involuntary drainage colostomy: possible regurgitation
42
Continent ileostomy
terminal ileum made into pouch with nipple valve and abdominal stoma APR for UC or FAP manually drained with catheter permanent
43
ideal conditions for a stoma
w/in rectus muscle to decrease risk of hernia flat surface to create a seal that's less likely to break patient should be able to see it, but it should be hidable
44
Normal output for ileostomy
1500-1800 ml/day at first then bowels adapt and increase absorption, so volume is 500 ml/day
45
Post op for IPAA
transient incontinence of mucus kegel exercise after 4 weeks perianal skin care phantom rectal pain
46
Special considerations to optimize poop when you have an ileostomy
2-3 L of water per day Chew food thoroughly especially meat, food with skinds, and hard foods
47
Sex stuff with ileostomies
males may have temporary ED for 3-12 months females may have less sensation, dryness, or orgasm issues --> no pregnancy issues though
