Q

incisional/ventral hernias are more prevalent in?

A

obese males

23
Q

what are risk factors for hernias?

A 
Increased intra-abdominal pressure: coughing, heavy lifting, constipation, pregnancy
Obesity
Advanced age
Smoking
Steroid use
24
Q

what are the 2 types of inguinal hernias

A

Direct

Indirect

25
Q

Direct hernia?

A

Usually acquired, herniation through defect in the posterior inguinal wall (through Hesselbach’s triangle) – occurs most commonly in older males

26
Q

Indirect hernia?

A

Usually congenital, through deep inguinal ring, lies within the spermatic cord, and the hernia sac is covered by the cremaster muscle – occurs most commonly in younger males and may be in scrotum

27
Q

What will a hernia feel like on index finger?

A

an indirect hernia will be felt on finger tip

a direct hernia will be felt on pulp of finger

28
Q

what is the gold standard treatment for hernia?

A

herniorraphy

29
Q

what must you do with a patient who has a incarcerated hernia?

A

a non-reducible hernia should be referred to a surgeon

30
Q

how should a patient be positioned when reducing a hernia?

A

have patient lying supine

31
Q

what type of hernia is a surgical emergency?

A

stangulated hernia because it compromises the bowel and can lead to an infarcted bowel

32
Q

what should be done with pediatric hernias?

A

complication rate is 20X higher in emergent pediatric hernia repair so need referral to pediatric surgeon

33
Q

Femoral hernia facts

A

84% of femoral hernias occur in women
25% of femoral hernias become incarcerated or strangulated
hernia protrudes through the femoral canal and is palpated on upper thigh

34
Q

what will the history be like in patients with femoral hernia’s

A

may complain of intermittent groin mass/bulge or pain
presenting feature may be small bowel obstruction due to incarceration/strangulation
Elderly patients may be asymptomatic even in the face of incarceration
Consider occult femoral hernia in females presenting with a small bowel obstruction

35
Q

what will a femoral hernia PE be like

A

bulge just BELOW the inguinal ligament

Tenderness if incarcerated

36
Q

Tx for femoral hernia

A

referral to surgeon

37
Q

Umbilical hernia facts

A

congenital defect
African American>Caucasians
Most newborn umbilical hernias close spontaneously by age 2
Patient with ascites have a higher incidence of umbilical hernia
low rate of incarceration

38
Q

umbilical hernia presentation

A

painless bulge around umbilicus
present with gastric symptoms
associated with obesity in adults
In kids under 2 wait for spontaneous closure unless LARGE

39
Q

what is a Spigelian hernia?

A

protrudes through the spigelian fascia near the terminus of the tranversus abdominis muscle along the lateral edge of rectus abdominis

40
Q

why is a spigelian hernia hard to dx

A

because hernia lies between abdominal muscles so there is no bulge
Its a rare hernia but easily missed and therefore potentially dangerous

41
Q

spigelian hernia presentation?

A

ofter patient present with obscure abdominal pain and no apparent cause

42
Q

spigelian hernia tx

A

surgery

43
Q

Hiatial hernia fast facts

A

reflux barrier composed of two components working together to prevent reflux:
Lower esophageal sphincter
crural diaphragm
stomach can herniate up through diaphragm into thoracic compartment will hear bowel sounds in chest cavity
once stretched by herniated stomach muscles the crural diaphragm cannot provide adequate pressure to prevent gastric contents moving into herniated region

44
Q

what will the history of a patient with hiatial hernia be like?

A

presents with symptoms similar to GERD, post prandial pain, bloating, early satiety, SOB with meals

45
Q

what diagnostics would you want to order for hiatial hernia

A

CXR- look for air fluid levels in mediastinum
Barium swallow
EGD
Esophageal manometry
surgery is not done unless all other medical options have been exhausted

46
Q

TX for hiatial hernia that is found accidently and asymptomatic

A

no tx needed

47
Q

if pt is symptomatic

A

trail of medical management similar to GERD

Surgical management is major surgical procedure

48
Q

Incisional or ventral hernia fast facts

A 
occurs at site of previous surgery
results from dehiscence of abdominal cavity
Causes:
Infection
malnutrition
obesity
flawed wound closure
Conditions that increase abdominal pressure
49
Q

what will history be like for patient with incisional or ventral hernia

A

prior Hx of surgery
presence of previously pre-disposing factors
complaints of intermittent or persistent bulge at incision site

50
Q

tx for incisional hernia

A

definitive tx is surgical repair

high incidence of recurrence if contributing factors are not controlled

51
Q

sport hernia fast facts

A

called athletic pubalgia
seen in high performance athletes
painful musculotendinous injury to medial inguinal floor caused by and exacerbated by vigorous sport or physical exertion
can occur in sports where there is much rapid lateral movement
hockey, soccer or sports with short off seasons
NOT A TRUE HERNIA

52
Q

what is history like of pt with sports hernia

A

usually high performance athlete with history of groin or lower abdominal pain aggravated by physical activity and relieved by rest
no complaints of bulge or mass

53
Q

what will PE be like for a sports hernia

A

tenderness over pubic ramus

no evidence of true hernia or lower abdominal pathology

54
Q

Tx for sports hernia

A

conservative tx: activity modification, PT

if no helping consider surgical intervention
