Changing trends in surgery for abdominal Crohn's disease

Area of Science:

• Gastroenterology
• Surgical Oncology
• Inflammatory Bowel Disease

Background:

• Biological agents and laparoscopy have significantly advanced Crohn's disease (CD) management in the last two decades.
• Increased efficacy of biologics for mild CD suggests a potential rise in complex surgical cases.

Purpose of the Study:

• To analyze the evolving characteristics and outcomes of surgical interventions for CD over a 13-year period.
• To compare surgical treatment data between two distinct timeframes (2004-2010 and 2011-2016).

Main Methods:

• Retrospective identification of all patients undergoing abdominal surgery for CD between 2004 and 2016.
• Comparative analysis of demographic, clinical, and treatment data between the periods 2004-2010 and 2011-2016.

Main Results:

• A total of 908 procedures were analyzed, with significant changes observed over time, including increased comorbidities and anti-tumour necrosis factor (anti-TNF) use.
• The second period (2011-2016) showed a higher incidence of penetrating CD, increased laparoscopic approach utilization, and decreased intra-operative blood loss.
• Despite increased comorbidities and biologic use, postoperative morbidity rates remained stable between the two periods.

Conclusions:

• The study highlights that despite a higher prevalence of comorbidities and the use of biologics in Crohn's disease patients undergoing surgery, postoperative morbidity has not increased.
• Increased adoption of laparoscopic techniques and reduction in intra-operative blood loss appear to have mitigated the impact of increased patient comorbidity.
• These findings underscore the evolving landscape of surgical management for Crohn's disease, balancing complex patient profiles with advancements in surgical techniques.
