ObjectiveTo elucidate the characteristics of colonic Crohn’s disease (CD) and evaluate effectiveness of surgical treatment.MethodClinical data of 28 cases with colonic CD who underwent surgery at West China Hospital of Sichuan University between Feb. 2009 and Jan. 2017 were retrospectively analyzed.ResultsDefinite diagnosis of colonic CD was performed in 12 cases preoperatively (42.9%), but 16 cases (57.1%) were misdiagnosed as other disease, ulcerative colitis (5 cases, 17.9%), tumor (4 cases, 14.3%), appendiceal disease (4 cases, 14.3%), and intestinal tuberculosis (3 cases, 10.7%) were the major causes of preoperative misdiagnosed disease. Of the 28 cases, elective surgery was performed in 26 cases and emergency surgery in 2 cases. The major surgical procedures were segmental colectomy(10 cases) and right hemicolectomy (6 cases), as well as ilecolostomy (9 cases), colocolostomy(6 cases), ileostomy(9 cases), colostomy (6 cases), and so on. The length of the first hospital stay of operation related to intestinal lesions in this group was 5–74 d (mean of 25.4 d). Postoperative complications were occurred in 9 cases (32.1%), all these cases didn’t receave medical treatment. Twenty cases were followed up, and the follow-up time was 7–78 months (mean of 33.4 months), 8 cases lost follow-up. The prognosis of the follow-up cases was good.ConclusionsColonic CD has occult clinical manifestation, resulting in misdiagnosis and mistreatment. Segmental resection of the colon is the important treatment for colonic CD. For patients with complications, multidisciplinary diagnosis and treatment is necessary. In addition, systematic medical treatment before surgery helps to reduce the risk of the first surgery associated with intestinal lesions.
