Anastomotic leak after ileocolic resection for Crohn's disease: The latest evidence

Studies have indicated that approximately half of individuals with Crohn's disease (CD) may undergo surgery at some point during their lifetime. Ileocolic resection (ICR) is the most frequently performed procedure for treating CD. Addressing anastomotic leak (AL) remains a critical focus in the perioperative and postoperative care of CD patients. A research study published in the World Journal of Gastrointestinal Surgery by Cwaliński et al included 77 individuals who had open ICR and primary stapled anastomosis to assess the risk factors linked to anastomotic insufficiency. At present, research on anastomotic insufficiency has focused on AL. Therefore, this editorial mainly analyzes the current risk factors linked to AL after ICR and discusses potential prevention strategies. We comprehensively consider risk factors such as body weight, medication use, surgical history, smoking, penetrating behaviour, and albumin levels to stratify patient risk. Based on recent research insights, we propose that individualized surgical timing, approaches, and techniques should be selected according to the patient's risk level.
