Background: Our study evaluated if the presence of inflamed resection margins increased postoperative anastomotic complications in Crohn's disease patients.
Methods: Resection margins of 70 patients operated on due to Crohn's disease were analysed and classified by a single pathologist according to the degree of inflammation. Anastomotic complications defined as anastomosis failure or postoperative perianastomotic abscess were recorded with a 1-month follow-up. The Fisher's exact test was used to analyse if the degree of inflammation in the resection margin increased anastomotic complications.
Results: Altogether 46 patients (65.6%) had inflammation in their bowel resection margins. 12 patients (17.1%) had mild, 5 patients (7.1%) intensive and 29 patients (41.4%) very intensive inflammation in their resection margins. The presence of inflamed resection margin did not significantly influence the appearance of postoperative anastomotic complications (p>0.05). Only 3 patients (4.6%) had anastomotic complications including two anastomotic failures and one abscess.
Conclusions: Our study did not show correlation between the degree of inflammation in the bowel resection margin and the presence of postoperative anastomotic complications in Crohn's disease. Bowel conservative surgery with resection of only the most affected bowel segments should be chosen for Crohn's disease patients.
