Synopsis
Refer for IBD surgery before avoidable physiological decline, prepare patients for realistic operative choices, manage stoma complications, and prevent or detect Crohn postoperative recurrence objectively.
- IBD surgery is indicated for emergency complications, medically refractory disease, fixed structural damage, dysplasia or cancer, and sometimes a patient preference for a more predictable life.
- Crohn surgery treats the complication but does not cure the disease; preserve bowel length where safe and plan recurrence prevention before discharge.
- In acute severe UC, deteriorating toxic megacolon, perforation, major haemorrhage or failed medical rescue requires timely subtotal colectomy rather than repeated immunosuppression.
- Elective UC choices include proctocolectomy with permanent end ileostomy or restorative pouch surgery in suitable patients; function, fertility, continence and pouchitis risks require specialist counselling.
- Preoperative optimisation addresses sepsis, corticosteroid burden, anaemia, malnutrition, smoking, thrombosis, immunosuppression and stoma marking without delaying a necessary emergency operation.
- A high-output ileostomy can cause sodium, water, magnesium and renal loss even when the patient drinks large volumes of plain water; early specialist fluid advice is crucial.
- Crohn postoperative recurrence often appears endoscopically before symptoms, so a well patient still needs risk-stratified prophylaxis and planned ileocolonoscopy or imaging.
- Pouch frequency alone does not diagnose pouchitis; assess infection, cuffitis, Crohn disease of the pouch, mechanical problems and functional disorders before repeated antibiotics.
Key red flags
A new stoma that becomes dusky, black, deeply retracted or stops functioning with pain and vomiting needs urgent surgical review for ischaemia, obstruction or retraction.
Oliguria, syncope, hypotension, rising creatinine or severe electrolyte abnormality with high ileostomy loss requires emergency fluid and renal assessment.
Postoperative fever, worsening abdominal pain, tachycardia, ileus or purulent wound drainage may indicate anastomotic leak or intra-abdominal sepsis.
Acutely prolapsed stoma that is painful, irreducible, ischaemic or obstructed requires immediate colorectal assessment.
Do not delay urgent colectomy for toxic colitis to complete nutrition, biologic washout or every elective counselling step.
Investigation priorities
Define obstruction, perforation, abscess, anastomotic leak or postoperative collection in an acute presentation.
Management branches
Structural complication, dysplasia, refractory inflammation, repeated steroid dependence or unacceptable quality of life makes an operation plausible.
- Define the surgical question with current endoscopy, imaging, pathology and medical history, separating active inflammation from fibrosis, sepsis and malignancy risk.
- Discuss options jointly with an IBD colorectal surgeon before exhausting every medicine, including expected bowel function, recurrence and the option of no operation now.
- Optimise anaemia, nutrition, smoking, infection, steroid exposure and thrombosis risk, and involve stoma nursing for marking and practical education.
- Set timing from urgency: optimise elective risk where possible, but do not allow a checklist to delay source control, obstruction relief or lifesaving colectomy.
