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

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.

What is the most appropriate treatment for this patient?A. AppendectomyB. AntibioticsC. Percutaneous drainageD. Watchful waiting

Management of NonperforatedAppendicitis

Appendectomy Historically treatment of choice Highly effective Higher rate of complications (20% vs. 7% w/

antibiotics alone)

Salminen P, Paajanen H, Rautio T et al. Antibiotic Therapy vs Appendectomy for Treatment of Uncomplicated Acute Appendicitis: The APPAC Randomized Clinical Trial. JAMA. 2015;313(23):2340-2348.

Management of NonperforatedAppendicitis

IV antibiotics Improved PO antibiotics to complete 10 day

course Not improved appendectomy About 10% had surgery within 1 mo. About 25% had recurrence/surgery within 1 yr.

Appendicitis: Red Flags

Signs of perforation Fever Increased pain Palpable mass Abdominal rigidity Could see improvement in pain (think of a walled-

off ruptured abscess) until peritonitis more fully develops

Management of Perforated Appendicitis

Complicated (septic, unstable, generalized peritonitis) Appendectomy IV antibiotics x 3-5 days

Management of Perforated Appendicitis

Stable, localized peritonitis Phlegmon: IV antibiotics Abscess: percutaneous drainage + IV antibiotics Improved PO antibiotics to complete 7-10 day

course + follow-up in 6-8 weeks Not improved appendectomy + IV antibiotics x

3-5 days

Appendicitis: Red Flags

Higher proportion of patients with perforated appendicitis at the extremes of age (early childhood, elderly) May be due to lower

incidence, because absolute rate of perforation is constant across ages

Crit Care Med 2008 Apr;36(4):1330-49.

Postop fever

Recommendations for Evaluation of Fever Within 72 Hours of Surgery CXR, UA, UCx not mandatory if fever is only

indication UA, UCx in febrile patients w/ indwelling catheter

> 72 hrs High level of suspicion for VTE in at-risk patients Open & culture incisions w/ signs of infection

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

I & D of Skin Abscesses I & D alone is usually sufficient for uncomplicated abscesses

Indications: Large abscess > 10 cm, cellulitis, immunocompromised, multiple or recurrent abscesses, extremes of age, failure of I&D alone

Slight benefit using antibiotics after I&D of uncomplicated abscesses Increase cure rate by 7-12% (NNT = 8-14) Already high cure rates in control group 70%+

Clearing C-spines: NEXUS Criteria

When a significant mechanism of injury is present, get a X-ray if: Neurological deficit Spinal tenderness (posterior midline cervical) Altered mental status/level of consciousness Intoxication Distracting injury

Clearing C-spines:Canadian C-Spine Rule

Only applies to GCS = 15 and stable trauma Not applicable for:

GCS < 15 Non-trauma Hemodynamically unstable Age < 16 Acute paralysis Previous spinal disease or surgery


1. X-ray if ANY of the following High Risk factors: Age > 65 years Dangerous mechanism

fall from elevation 3 feet / 5 stairs axial load to head, e.g. diving MVC high speed (>100 km/hr), rollover, ejection motorized recreational vehicles bicycle struck or collision

Parasthesia in extremities


2. If ANY Low-Risk factor present, assess clinically with ROM testing (If all NO: x-ray) Simple rear-end MVC, excluding the following:

pushed into oncoming traffic hit by bus / large truck rollover hit by high speed vehicle

Sitting position in ED Ambulatory at anytime Delayed (not immediate) onset of neck pain Absence of midline C-spine tenderness


3. (If at least 1 low-risk factor present) Able to actively rotate neck 45 degrees left and right?

If able then NO x-ray needed If unable, X-ray.

Clearing C-spines: Which is Better?

Sensitivity: Canadian 99.4% vs. NEXUS 90.7% Specificity: Canadian 45.1% vs. NEXUS 36.8%

VASCULAR SURGERY

Peripheral Vascular Disease

Peripheral Vascular Disease

Risk Factors = older age, smoking, diabetes mellitus, hypertension, hyperlipidemia, renal insufficiency

Key symptom = Intermittent claudication (only 10% have classic symptoms)

Hennion DR, Siano KA. Diagnosis and Treatment of Peripheral Arterial Disease. Am Fam Physician. 2013 Sep 1;88(5):306-310.

Peripheral Vascular Disease: Diagnosis

Physical exam: Skin: cool, shiny, absence of hair, nonhealing

wounds, distal extremity pallor on elevation Vascular: nonpalpable distal pulses, bruits,

abnormal capillary refill time

Ankle-Brachial Index (ABI) highly sensitive (90%) and specific (98%)

USPSTF I recommendation for screening


Peripheral Vascular Disease: Nonsurgical Treatment

Activity and lifestyle modification: smoking cessation, exercise (supervised better than unsupervised)

Medications: Antiplatelet: aspirin 75-325 mg or clopidogrel 75 mg

daily. Ticagrelor no better than clopidogrel. Statin Cilostazol - lifestyle-limiting claudication without heart

failure. Pentoxifylline second-line (cilostazol more effective

in head-to-head studies)

Hennion DR, Siano KA. Diagnosis and Treatment of Peripheral Arterial Disease. Am Fam Physician. 2013 Sep 1;88(5):306-310.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: Surgical Treatment

Emergent: Critical limb ischemia (1% of presentations - tissue loss, gangrene, or chronic pain at rest)

Lifestyle-limiting claudication symptoms that do not respond to exercise and pharmacologic treatment

Not enough evidence to favor bypass surgery over angioplasty

Hennion DR, Siano KA. Diagnosis and Treatment of Peripheral Arterial Disease. Am Fam Physician. 2013 Sep 1;88(5):306-310.Fowkes F, Leng GC. Bypass surgery for chronic lower limb ischaemia. Cochrane Database of Systematic Reviews 2008, Issue 2. Art. No.: CD002000. DOI: 10.1002/14651858.CD002000.pub2.

Peripheral Artery Disease: Prognosis80/20 rule over 5 years . . .

70 -80% stable claudication 10-20% worsening claudication 1-2% progressed to critical limb ischemia 1-4% limb amputation


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

USPSTF Recommendation for Ultrasound Screening for AAA

One time screening in men aged 65-75 who have ever smoked (B recommendation)

No recommendation for or against screening in men aged 65-75 who have never smoked (C recommendation)

Recommends against routine screening in women (D recommendation)

Coronary Artery Disease

Hggstrm M. File:Coronary arteries.png [Wikimedia Commons Web site]. January 19, 2011. Available at: http://commons.wikimedia.org/wiki/File:Coronary_arteries.png .

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

Transcatheter vs. SurgicalAortic 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

UROLOGY

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, postobstructivediuresis

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

Kidney and Ureter Stones:Indications for Surgery

No passage after reasonable period of time Constant pain Hydronephrosis Damaging kidney tissue Constant bleeding Ongoing urinary tract infection Too large to pass on its own or stuck Growing larger
