abstract
AIM: The introduction of biological agents and laparoscopy are, arguably, the most important developments for the treatment of Crohn's disease (CD) in the last two decades. Due to the efficacy of biological agents in treating mild disease, it is likely that the percentage of surgery for complex cases may have increased. The objective of this study was to analyse the changing characteristics and results of the surgical treatment of patients with CD over the past 13 years. METHODS: All patients who underwent abdominal surgery for CD between 2004 and 2016 were retrospectively identified. Data were compared between two periods (2004-2010 and 2011-2016). RESULTS: A total of 908 procedures were performed (48% men, mean age 43 ± 16 years). Demographic and CD characteristics changed significantly over time: comorbidities were more frequent (35% vs 46%, P < 0.0001), and preoperative steroids (28% vs 36%, P < 0.01) and anti-tumour necrosis factor (20% vs 40%, P < 0.0001) treatments were more frequently used in the second period. Smoking (14% vs 8%, P < 0.0001) and use of immunosuppressors (32% vs 22%, P < 0.001) decreased significantly. More cases of penetrating disease (22% vs 32%, P < 0.001) were operated upon in the second period. The laparoscopic approach (49% vs 57%, P < 0.04) was more frequently performed and mean blood loss (167 ± 222 vs 123 ± 243 ml, P < 0.01) decreased significantly. Postoperative morbidity did not change between the two periods. CONCLUSION: Despite a higher incidence of comorbidities and the use of biologics postoperative morbidity remained unchanged. An increased use of laparoscopy and a decreased intra-operative blood loss may have contributed to offsetting the impact of increased comorbidity.
