Cholangiocarcinoma
Cholangiocarcinoma
Treatment: complete surgical resection Generally poor prognosis
Only 10% present at an early enough stage to consider curative resection
5-year survival rate up to 40% for patients with completely resected tumors
Cholangiocarcinoma: Klatskin tumor

Imaging: ACR appropriateness criteria
Classical presentation CT abd/pelv w/ contrast (8 usually appropriate) CT abd/pelv w/o contrast (7 usually appropriate) RLQ US (6 may be appropriate)
Atypical presentation CT abd/pelv w/ contrast (8 usually appropriate) X-ray abd, RLQ US, pelvic US, CT abd/pelv w/o
contrast (6 may be appropriate) American College of Radiology. ACR Appropriateness Criteria: Right Lower Quadrant Pain - Suspected Appendicitis. Available at https://acsearch.acr.org/docs/69357/Narrative/. Accessed 24 February 2017.
Bottom Line: Diagnosis of Appendicitis
H&P and labs low sensitivity and specificity by themselves
CT and MRI have better sensitivity/specificity compared to H&P and labs; ultrasound slightly less sensitive than CT/MRI (studies varied widely)
No single lab or clinical test has superior sensitivity or specificity. Specific cutoffs could not be defined.

Appendicitis: Red Flags
Signs of rupture Change in condition:
Fever Increased pain Abdominal rigidity
Could see improvement in pain (think of a walled-off ruptured abscess) until peritonitis more fully develops
Appendicitis: Red Flags
Higher proportion of patients with ruptured appendicitis at the extremes of age (early childhood, elderly) May be due to lower
incidence, because absolute rate of rupture is constant across ages

Preoperative Workup
Elevated cardiac risk and poor or unknown functional capacity
Only if a positive test would change management
Stress Tests
Preoperative Workup
CXR: New or unstable
cardiopulmonary signs or symptoms
Increased risk of postop pulmonary complications if results would change management
UA: Urologic procedures Implantation of foreign
material (e.g., heart valve or joint replacement)
Preoperative Workup
BMP: At risk of electrolyte
abnormalities or renal impairment (based on history, medications)
Glucose, A1c: Signs/symptoms or very
high risk of undiagnosed diabetes, if abnormal result would change periop management
CBC: At risk for anemia Significant blood loss
anticipated
Coags: On anticoagulants History of abnormal

Perioperative Areas of Focus
Anticoagulation management Venous thromboembolism (VTE) prevention Beta-blocker therapy Antibiotic prophylaxis Chronic disease
Anticoagulation Stop ASA 7-10 days (3 days?) pre-op (unless benefit
preventing ischemia outweighs bleeding risk), restart 8-10 days post-op
Stop warfarin 4-5 days pre-op Stop heparin

Venous Thromboembolism
Assess risk Check renal function Consider prophylaxis Bridge therapy (treat w/ LMWH after holding
warfarin) for patients with mechanical heart valve, h/o VTE
BRIDGE trial: Do patients w/ atrial fibrillation on warfarin need bridge therapy with LMWH when warfarin is held pre-op?
Placebo was noninferior to LMWH with respect to preventing atrial thromboembolism
More bleeding complications in LMWH group Excluded patients: stroke, mechanical valves Relatively low risk population (only 13% high-
risk by CHADS2)

Care of Surgical Wound
Sterile dressing 24-48 hrs Minor surgical wounds can be allowed to get
wet in the first 48 hours without increasing risk of infection
Extremity wounds may be covered with a clear film dressing (reduced rate of blistering, exudates)
Case: 23 yo man with swelling, redness, pain, pus from thigh

VASCULAR SURGERY
Peripheral Vascular Disease
Peripheral Vascular Disease
Intermittent claudication (many may not have classic symptoms)
Late symptoms: rest pain, ulcers, gangrene Risk Factors = CAD, esp. smoking Diagnosis: ABI, PE pulses, bruits, hair loss
(watering the plants), poor nail growth, dependent rubor, ulcers
Peripheral Vascular Disease
Treatment: modify risk factors, exercise, meds (ASA, clopidogrel, cilostazol)
Ticagrelor no better than clopidogrel Hiatt WR, Fowkes FG, Heizer G, et al. Ticagrelor versus Clopidogrel in Symptomatic Peripheral Artery Disease. N Engl J Med. 2017 Jan 5;376(1):32-40.
Peripheral Vascular Disease
Surgery: not enough evidence to favor bypass surgery over angioplasty

Medical vs. Surgical Management: Asymptomatic Carotid Artery Stenosis
No evidence clearly favoring: Carotid endarterectomy vs. carotid artery
stenting Surgery vs. medical management
Low rates of ipsilateral stroke in patients managed medically 1.68% all studies, 1.18% newer studies

Indications for CABG
Disease in left main, or all 3 coronary vessels (L Cx, LAD, RAD)
Diffuse disease not amenable to PCI Severe CHF, diabetes
Valvular Surgery: Stenotic vs. Regurgitant Lesions
Stenotic: can be monitored until symptoms appear
Regurgitant: may require surgery even if asymptomatic carefully monitor LV function by echo
Aortic Stenosis: Bicuspid Aortic Valve

Aortic Stenosis
Classical presentation: asymptomatic, then angina, exertional syncope, dyspnea
After symptoms develop Average survival 2-3 years 75% die w/in 3 yrs w/out valve replacement
Aortic Stenosis: Workup
Echocardiogram mild/moderate AS q2-5 yrs severe AS annual (to check LV function)
Critical stenosis: Valve area < 0.8 cm2 or gradient > 50 mm Hg
CXR, EKG CT (thoracic ascending aortic aneurysm) NO stress testing
Transcatheter vs. Surgical Aortic Valve Replacement
Clear mortality benefit in high-risk pts w/ severe aortic stenosis (NNT = 20 to avoid 1 death at 1 year)
Similar benefit in intermediate-risk patients at 2 years

Mitral Stenosis
Symptoms mimic CHF Atrial fibrillation, pregnancy bring out
symptoms
Mitral Stenosis: Treatment
Mild disease: diuretics Atrial fibrillation: rate control Surgery: > mild symptoms, or pulmonary
hypertension Balloon valvotomy, open commisurotomy, MV
reconstruction, MV replacement
Aortic Regurgitation
Causes: endocarditis, rheumatic fever, collagen vascular disease, aortic dissection, syphilis
Typical presentation: Initially asymptomatic, then subtle initial signs (decreased functional capacity or fatigue), then sx of L-sided heart failure
Aortic Regurgitation: Treatment
AV replacement even in asymptomatic patients before EF < 55 % or end systolic dimension
reaches 55 mm
Severe AR + normal LV function: afterload reduction w/ vasodilators, especially
nifedipine, can delay surgery
Mitral Regurgitation
Causes: infectious endocarditis, mitral valve prolapse, rheumatic fever
Surgery: if > mild sx If asymptomatic but EF < 60%, or end-systolic
dimension approaches 45 mm Usually MV repair preferred over replacement
What about Mitral Valve Prolapse?
Typical symptoms: chest pain, dyspnea, anxiety, palpitations
Treatment: reassurance no need for surgery

Urinary Retention
Hellerhoff. File:Harnverhalt.jpg [Wikimedia Commons Web site]. January 8, 2010. Available at: http://commons.wikimedia.org/wiki/Harnverhalt.jpg.
Urinary Retention: Treatment with Catheterization
Look out for: hematuria, hypotension, postobstructive diuresis
How long to leave in? Unknown in pts with known or suspected BPH Alpha blocker at time of catheter insertion x 3 d. can
increase chance of returning to normal voiding Urinary retention from BPH: at least one trial of voiding
without catheter before considering surgical intervention Long-term treatment with 5-alpha reductase inhibitors can
prevent acute urinary retention in men with BPH
