Summary
Long-term corticosteroid therapy is linked to higher complication rates after Crohn's disease surgery. Preoperative steroids and intra-abdominal abscesses significantly increase reoperation risks for patients undergoing intestinal anastomosis.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Clinical Medicine
Background:
- Crohn's disease often necessitates intestinal surgery, with anastomoses being a common procedure.
- Perioperative morbidity following intestinal anastomosis for Crohn's disease requires careful risk factor assessment.
Purpose of the Study:
- To prospectively identify variables associated with perioperative morbidity in patients undergoing intestinal anastomosis for Crohn's disease.
- To determine the impact of specific factors on complication and reoperation rates.
Main Methods:
- Prospective study of 658 intestinal anastomoses in 429 Crohn's disease operations over 8 years.
- Multivariate analysis using stepwise logistic regression to identify significant risk factors.
Main Results:
- Overall complication rate was 9.7%, with 4% requiring reoperation and 0.5% mortality.
- Long-term corticosteroid therapy was significantly associated with overall complications (p=0.03).
- Intra-abdominal abscesses (p=0.01) and preoperative steroid use (p=0.03) increased serious complications; combined, they raised reoperation rates to 16%.
Conclusions:
- Long-term corticosteroid use is a significant predictor of overall complications after intestinal anastomosis in Crohn's disease.
- The presence of intra-abdominal abscesses and preoperative steroid use are critical risk factors for serious complications and reoperations.
- Many other factors, including age, sex, disease duration, and surgical details, were not significantly associated with postoperative complications.
