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 />

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 />

• 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

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 />

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 />

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

Medical <strong>Management</strong><br />
• Steroids<br />

osteomalacia<br />
• Budesonide, beclomethasone undergo rapid<br />
hepatic degradation to limit systemic toxicity

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