Abstract:

Objective To analyze the risk factors of appendiceal orifice inflammation (AOI) in patients with ulcerative colitis (UC) and the influence of AOI on the prognosis of UC. Methods A total of 288 UC patients were enrolled, of them 105 were AOI positive and 183 were AOI negative. The medical records of UC patients who underwent colonoscopy and treatment in the department of colorectal surgery were collected, and data including gender, age, medical history, colonoscopic lesion involvement and Mayo endoscopic subscore, microscopic pathological features and treatment. All patients were divided into two groups according to AOI. The demographics and endoscopic features of the two groups were analyzed. Logistic regression was used to analyze risk factors of AOI in UC patients. Kendall grade correlation was used to analyze the correlation between AOI inflammatory grade and rectal inflammatory grade in AOI-positive UC patients. Results There were no significant differences in age, gender and clinical classification between the two groups. There were significant differences in the scope of lesion involved and Mayo endoscopic subscore between the two groups (P<0.05). Multivariate Logistic regression analysis showed that wide lesion involvement and higher Mayo endoscopic subscore were independent risk factors for AOI (P<0.05). In AOI-positive UC patients, the grade of AOI pathological inflammation was positively correlated with the grade of rectal pathological inflammation (rs=0.512, P<0.05). After treatment, most patients achieved remission, and there was no significant difference in the therapeutic effect between AOI positive and AOI negative patients. According to the treatment methods, AOI positive patients with proctitis were divided into the suppository drug group and the suppository combined with oral drug group, and the remission rate was higher in the suppository combined with oral drug group than that of the suppository drug group (P<0.05). Conclusion The wider the scope of endoscopic lesion involvement and the higher the Mayo endoscopic subscore in UC patients, the more likely AOI positive is. The evaluation of AOI under the colonoscopy is beneficial to better guide the treatment of UC patients.
