Pre-operative Considerations• Timing of Surgery
• Unless there is a free perforation, emergency surgery is rarely indicated in patients with CD
• If a bowel obstruction is due to a Crohn’s stricture, it will almost always settle with non operative treatment
• Perforating disease with abscesses• Treat sepsis-drains, antibiotics, nutritional support
• Plan an elective or semi-elective procedure

Pre-operative Considerations• Image the GI Tract• Mark Stoma Site• Steroid Coverage, DVT prophylaxis, SSI preventionv Discontinuation of biologicals is probably not necessary
![Page 4: Challenges in Surgery for Small Bowel Crohn’s Disease€¦ · Challenges in Surgery for Small Bowel Crohn’s Disease Robin S. McLeod Departments of Surgery and Health Policy Management](https://reader033.vdocument.in/reader033/viewer/2022060313/5f0b58cd7e708231d43010d2/html5/thumbnails/4.jpg)
The “Routine” Ileocolic Resection
Principles:• Usually can be performed
laparoscopically• Remove all “gross disease”
and small margins of normal SB
• Stapled or handsewnanastomosis
![Page 5: Challenges in Surgery for Small Bowel Crohn’s Disease€¦ · Challenges in Surgery for Small Bowel Crohn’s Disease Robin S. McLeod Departments of Surgery and Health Policy Management](https://reader033.vdocument.in/reader033/viewer/2022060313/5f0b58cd7e708231d43010d2/html5/thumbnails/5.jpg)
The Difficult Mesentery
• Always be wary of the SB mesentery in Crohn’s disease• Take down all adhesions• Stay close to the bowel• Use the ligasure/energy
device for thick mesentery
![Page 6: Challenges in Surgery for Small Bowel Crohn’s Disease€¦ · Challenges in Surgery for Small Bowel Crohn’s Disease Robin S. McLeod Departments of Surgery and Health Policy Management](https://reader033.vdocument.in/reader033/viewer/2022060313/5f0b58cd7e708231d43010d2/html5/thumbnails/6.jpg)
Options:• Strictureplasty
• Heinecke Miculicz• Finney• Michelassi
• Resection
Multiple Strictures
![Page 7: Challenges in Surgery for Small Bowel Crohn’s Disease€¦ · Challenges in Surgery for Small Bowel Crohn’s Disease Robin S. McLeod Departments of Surgery and Health Policy Management](https://reader033.vdocument.in/reader033/viewer/2022060313/5f0b58cd7e708231d43010d2/html5/thumbnails/7.jpg)
Considerations• Is there sepsis present?• Is there a stricture at a previous
anastomosis?• How much bowel does the patient
have? (ie: has the patient had resections previously?)
• How much bowel would you have to remove if you resected the bowel now?
• Is it possible to perform strictureplasties (ie: is there enough normal bowel in between?)
• Resection plus strictureplasties might be an option

Strictureplasty• Reported complication rate 1-14%• Reported short term outcome is excellent• Re-operative rates (Hurst and Michelassi)
• 15% at 1 yr• 22% at 5 yr
• No consistent predictors of recurrence• ? Need for maintenance therapy

• Antibiotics• Drain the Abscess• Nutritional support
• May need enteral nutrition or TPN
• Plan surgery semi-electively• ? Wait time variable
• May obviate need for a stoma

• Joe is a 22 year old male• developed Crohn’s disease as a child• multiple drugs and operations over the years• Significant growth retardation
• Transferred to me from the children’s hospital at age 18 years• Small bowel resection and ileosigmoid anastomosis• minimal perianal disease• Over the next few years:
• perianal disease worsened• Multiple fistulas requiring drainage procedures on several occasions
• recurrence at the ileosigmoid anastomosis • Short stricture causing obstructive symptoms
Patient Story

• Family Situation• Very supportive family• Mother always comes to office visits; often father attends• Joe has one older brother
• Studying law at university• Joe’s situation
• Finished high school but has not been able to undertake post-secondary schooling nor work because of his Crohn’s disease
Patient Story
![Page 22: Challenges in Surgery for Small Bowel Crohn’s Disease€¦ · Challenges in Surgery for Small Bowel Crohn’s Disease Robin S.

• I recommend to Joe that he should have a proctectomy and permanent ileostomy
• Joe is undecided whether he wants to have surgery• He continues to have problems with his perianal disease and
intermittent obstructions• Joe is seen by one of our psychiatrists
Patient Story
![Page 23: Challenges in Surgery for Small Bowel Crohn’s Disease€¦ · Challenges in Surgery for Small Bowel Crohn’s Disease Robin S. McLeod Departments of Surgery and Health Policy Management](https://reader033.vdocument.in/reader033/viewer/2022060313/5f0b58cd7e708231d43010d2/html5/thumbnails/23.jpg)
• Joe tells the psychiatrist he is ambivalent about the surgery because he forsees that there are two possible outcomes:1. Unfavorable outcome:
• Joe views a stoma as his “last chance”• Currently he has hope because there is another option• But, if he has a stoma, and he continues to have problems, he
will be despondent because he won’t have anymore options2. Favorable outcome:
• He will not longer be “the sick child” and his family’s and his own expectations of him will be high
• Joe sees that both outcomes have risks for him

• Important to remember that Crohn’s disease is a chronic disease and surgery does not cure the patient of the disease.
• Thus, the question to the patient should not necessarily be: “What is the matter with you?”
but “What matters to you?”
