Difficult inpatients
The kind that are NOT eligible for clinical trials
Limited, if any, RCT data available
There are frequently NO right answers
Management through general principles, art,
analogy, and a bit of science
CASE 1
COMPLICATED CROHN’S DISEASE
Case 1: Crohn’s Disease
• 23 year old male with CD x 4 years
• Ileal and segmental colonic location
• Failed 5-ASA x 8m, Aza x 3 years, now referred after
starting IFX monotherapy x 4m
• Slowly worsening RLQ pain, fevers x 2 months
• CT Scan ordered
• Admitted with CRP 4.3, ESR 78,
Albumin 2.2, Prealbumin 3 after scan result.

Consultant Notes
• Radiology: 2.6 cm abscess medial to cecum,
adjacent to long (15 cm) TI stricture with active
inflammation. Unable to drain safely. Upstream SB
dilated to 3.6 cm.
• Surgery: No emergent indication for surgery.
Recommend maximize medical therapy to eliminate
inflammation and eradicate all infection before
elective surgery. Follow up in surgery clinic in 8
weeks.
Options?

Continue anti-TNF?
What are the anti-inflammatory options?
Anti-microbial therapy?
Surgical therapy?
Will this situation recur?
Will this damaged bowel be responsive to therapy?
Discuss…
Medical Therapies
• Anti-TNF
• Systemic steroids
• Topical steroids
– Entocort
• Immunomodulators
– Methotrexate
– Azathioprine
Abscess fertilizers
Anti-microbial therapy
• Drainage
– Would be optimal, not always possible
– 60-84% can be drained in case series with 2+ attempts
• Antibiotics
– Cover gut bugs broadly
– Consider iv for best bioavailability
– Consider early re-image (3-5d) if incomplete drainage
– Long term, re-image in 4-6 weeks
Waljee, Chapter 135, Advanced Therapy of IBD text, ed. Bayless and Hanauer
Feagins, Kane, et al, CGH 2011:842
Is Surgery Avoidable?
• Usually not
• Penet rating complications occur close to strictures
– Increased pressure within and upstream
– Inflammation weakens walls
• Likely to recur unless stricture fixed
– There are exceptions – inflammatory strictures
– Can you drain and start anti-TNF? 31% recur @5y N=55
• Goal is generally to get patient to ELECTIVE surgery
Nguyen, Sandborn, et al. CGH 2012: 400-4
Goals for pre-op visit
• Eradicate infection
• Control mucosal inflammation
– Even better, control transmural inflammation
– Limit/reduce length of resection
• “neoadjuvant” anti-TNF therapy?
• Prevent new fistulas, abscesses
• Boost nutritional status – Prealb, Alb
• Boost functional status – “Pre-hab”

Options?
• Prognosis?
• What are the rescue therapy options?
• How to dose/frequency of dosing?
– Where will drug go? How to monitor levels?
• Implications of surgery on fertility?
• What are long-term risks/benefits?
• Discuss….
An Extreme Paucity of Data…
• A fair amount of trial and error
– Trial and failure, learn from your mistakes
• IFX can leak out of colon into stool in surprisingly
large amounts
• CRP is invariably high, and falls with therapy
• Retrospectively developed prognostic indices help
– If steroids are not working by day 3, will not work
• In the CYSIF trial, IFX ~ Cyclo at 90 days
What Various IBD Centers Do
• Operate at Day 4
• Rescue with Cyclosporine (decreasing)
• Rescue with IFX
– Dose high (10 mg/kg)
– Dose often (5 mg/kg q 72h until CRP <1)
– Hybrids of these

Long et al. 2012
Diagnostic Criteria for Narcotic Bowel Syndrome
Chronic or frequently recurring abdominal pain that is treated with
acute high-dose or chronic narcotics and all of the following:
• The pain worsens or incompletely resolves with continued or escalating
dosages of narcotics.
• There is marked worsening of pain when the narcotic dose wanes and
improvement when narcotics are re-instituted (soar and crash).
• There is a progression of the frequency, duration, and intensity of pain
episodes.
• The nature and intensity of the pain is not explained by a current or
previous GI diagnosis.

Grunkemeier et al. 2007
Detoxification Protocol for Narcotic Bowel Syndrome (2)
Effective communication with the patient is essential.

Explanation of rationale/benefit of stopping the narcotics

Explanation of the withdrawal program.

Affirmation of the patient’s pain and an explanation of the underlying
pathophysiology of NBS (i.e. altered motility and/or visceral
hypersensitivity).
Total narcotic daily dose should be converted to morphine equivalents
using an appropriate calculator and the 24 hours total drug dose reduced
by 10-33% q 24 hours. In inpatients setting administration of morphine as
continuous infusion (not PRN).
Grunkemeier et al. 2007
Detoxification Protocol for Narcotic Bowel Syndrome (3)
• Start of TCA (e.g. desipramine, nortriptyline @25-150 mg/qhs) or SNRI
(e.g. duloxetine 30-90 mg. qd) for immediate and long terms pain control
and to help manage psychological comorbidities.
• Mirtazepine (15-30 mg. qhs) can be considered instead of or in addition to
a TCA or SNRI if nausea is a prominent feature.
• For withdrawal symptoms clonidine (start with 0.1 mg bid)
• For anxiety benzodiazepine (e.g. lorazepam 1 mg q 6 hours)
• For constipation e.g. PEG 3350 17 g bid
