Epiemiology<br />

• Incidence: 8-15/100,000<br />

• Incidence lower in Asia, Africa, S. America,<br />

& nonwhite Americans<br />

• Peaks in 3 rd & 7 th decades<br />

Schwartz 9 th ed, Maingot 11 th ed


www.downstatesurgery.org<br />

Etiology<br />

• Geographic differences suggest<br />

environmental (diet/infection)<br />

• Smoking, etoh, OCPs implicated<br />

• Genetic? 10-30% have + FH<br />

• autoimmune<br />

Schwartz 9 th ed, Maingot 11 th ed


www.downstatesurgery.org<br />

Pathophysiology<br />

• Poorly understood<br />

• Intestinal mucosa continually exposed to<br />

environmental challenge<br />

• chronic dysregulation <strong>of</strong> mucosal immunity<br />

• uncontrolled inflammatory response<br />

• IL-1B, 6, 8, TNF, prostaglandin (E2), leukotriene B4<br />

exacerbate mucosal inflammation<br />

• IL-4, 10 suppress intestinal inflammation<br />

Liu et al, Feb 2011<br />

• Sydney Australia; Neurogastroenterology Motility<br />

• Tachykinins, like substance P & neurokinin,<br />

hemokinin<br />

• Role in motility, secretion, and immune functions<br />

• Tachykinin receptor gene expression was 10-fold<br />

more abundant in colon mucosa <strong>of</strong> pts w/ UC<br />

compared to Control (p


www.downstatesurgery.org<br />

Pathology<br />

• Colonic mucosa & submucosa infiltrated w/<br />

inflammatory cells<br />

• Mucosal edema is the earliest manifestation<br />

• Ulcers are linear & knifelike<br />

• Atrophic mucosa & crypt abscesses common<br />

• mucosa is friable & may have inflammatory<br />

pseudopolyps<br />

• TI may demonstrate inflammatory changes<br />

(backwash ileitis)<br />

www.downstatesurgery.org<br />

Indications for Elective <strong>Surgery</strong><br />

• Intractability despite maximal medical<br />

therapy<br />

• High risk <strong>of</strong> complications from medical<br />

therapy<br />

• Significant risk <strong>of</strong> developing colorectal Ca<br />

Schwartz 9 th ed, Maingot 11 th ed


www.downstatesurgery.org<br />

Risk for Colorectal Ca<br />

• Increased w/ early age at Dx, increased<br />

duration, extent <strong>of</strong> Dz<br />

• Increased w/ duration<br />

• 2% after 10yrs & increases 0.5-1% annually<br />

afterward<br />

• 8% after 20yrs<br />

• 18% after 30yrs<br />

Schwartz 9 th edition, Maingot 11 th ed, Cameron 10 th ed


www.downstatesurgery.org<br />

Risk for Colorectal Ca<br />

• More likely to arise from areas <strong>of</strong> flat dysplasia<br />

making early Dx more difficult<br />

• => pts undergo (40-50) random Bx during<br />

colonoscopy<br />

• Annual surveillance after 8yrs for pts w/<br />

pancolitis, 15 yrs for pts w/ L. colitis<br />

• Ca may be present in up to 20% <strong>of</strong> pts w/ low<br />

grade dysplasia<br />

Proctocolectomy &<br />

Ileostomy<br />

• Single stage<br />

• Curative<br />

• Incontinent<br />

• Use <strong>of</strong> collecting device<br />

• 20% morbidity:<br />

• Hemorrhage, sepsis, neural injury<br />

Maingot 11th ed


Subtotal Colectomy &<br />

Ileal-rectal Anastomosis<br />

• No need for stoma<br />

• Pelvic autonomic nerves are undisturbed<br />

• Not curative, 20% proctectomy<br />

• Contraindicated in pts w/<br />

• Anal sphincter dysfunction, severe rectal Dz,<br />

rectal dysplasia, or malignancy<br />

Continent Ileostomy/ Koch Pouch


www.downstatesurgery.org<br />

Continent Ileostomy/ Koch Pouch<br />

• 45-50cm <strong>of</strong> terminal ileum is used<br />

• The proximal 30-35cm is fashioned into a pouch<br />

• The outflow tract is intussuscepted & sutured/stapled<br />

creating a nipple valve<br />

• The reservoir is sutured to the peritoneum & fascia<br />

• The efferent limb is externalized as a flush stoma<br />

• Passing a s<strong>of</strong>t plastic tube through the nipple valve<br />

empties the pouch<br />

Maingot 11th ed


• Offered a curative resection and continence<br />

• Complicated by<br />

www.downstatesurgery.org<br />

Continent Ileostomy/ Koch Pouch<br />

• Nipple valve failure requiring revision 60%<br />

• Enteritis, pouchitis, nonspecific ileitis<br />

• Fat & B12 malabsorption<br />

• Neural and perineal wound problems similar to that<br />

<strong>of</strong> standard proctocolectomy<br />

• Still 2/3 are satisfied after 30 yrs<br />

www.downstatesurgery.org<br />

Ileal J-Pouch<br />

• 15-20cm <strong>of</strong> the stapled <strong>of</strong>f TI is folded onto itself in the<br />

shape <strong>of</strong> a J<br />

• The distal/efferent limb is secured to the afferent limb<br />

• The pouch is formed using sequential firings <strong>of</strong> a 75-mm<br />

mechanical stapler applied through an enterotomy in the<br />

apex <strong>of</strong> the pouch<br />

• Pouch is filled w saline to check staple line (should hold 2-<br />

300cc)<br />

• Mobilize the SB mesentery so the pouch can reach the pelvis<br />

w/ no tension<br />

Double-<br />

Staple<br />

Ileal-anal<br />

Anastomosis


Mucosectomy vs Double<br />

Staple<br />

• Double Staple = retained rectal mucosa => potential<br />

for proctitis & Ca<br />

• Double staple <br />

• Increased anal resting pressure<br />

• Preservation <strong>of</strong> the rectoanal inhibitory reflex<br />

• Improved continence<br />

• Fewer septic complications<br />

• Other studies have shown no difference<br />

• => surgeon’s preference<br />

Medical <strong>Management</strong> - Salicylates<br />

• Sulfasalazine<br />

• Inhibition <strong>of</strong> cyclooxygenase & 5-lipoxygenase in gut<br />

mucosa & => decrease inflammation<br />

• Pentasa(mesalamine), asacol, rowasa, canasa<br />

• remission 80% @3g/day<br />

• Sulfapyradine attached to 5-ASA which is cleaved by<br />

enteric bacteria inflammatory side effex<br />

• Oral, topical, or combo<br />

• Drug <strong>of</strong> choice for mild to moderate disease


www.downstatesurgery.org<br />

Medical <strong>Management</strong><br />

• Steroids<br />

• Moderate to severe<br />

• HTN, hyperglycemia, cataracts, osteoporosis,<br />

osteomalacia<br />

• Budesonide, beclomethasone undergo rapid<br />

hepatic degradation to limit systemic toxicity


www.downstatesurgery.org<br />

Medical <strong>Management</strong><br />

Immunosuppressive Agents<br />

• Azathioprine, 6-MCP<br />

• Interfere w/ nucleic acid synthesis<br />

• Good for those who failed salicylate Tx or are dependent on<br />

steroids (6-12 wk onset <strong>of</strong> axn)<br />

• Cyclosporine<br />

• Interferes w/ T cell funxn<br />

• Helps acute flares 80%<br />

• Methotrexate<br />

• Folate antagonist<br />

• Infliximab (Remicade)<br />

• Monoclonal Ab against TNF alpha<br />

• >50% w/ moderate to severe Dz respond

Extraintestinal Manifestations<br />

• Liver most common: fatty liver 40-50% reverse by med<br />

or Sx, cirrhosis (2-5%) irreversible<br />

• Primary sclerosing cholangitis strixrs <strong>of</strong> intra &<br />

extrahepatic ducts (40-60% have UC) only effective<br />

therapy is liver transplant<br />

• Cholangiocarcinoma rare but pts r ~20yrs younger than<br />

typical pts w/ it<br />

• Arthritis improves w/ meds or Sx but sacroiliitis or<br />

ankylosing spondylitis does not<br />

• Erythema nodosum 5-15%, W:M 3-4:1, raised red & on<br />

lower legs & pyoderma grangenosum some may improve<br />
