| 3 | Patients with Clostridium difficile infection and prior appendectomy may be prone to worse outcomes显示文摘BACKGROUND Clostridium difficile infection(CDI)occurs due to a dysbiosis in the colon.The appendix is considered a‘safe house’for gut microbiota and may help repopulate gut flora of patients with CDI.AIM To study the impact of prior appendectomy on the severity and outcomes of CDI.METHODS We retrospectively reviewed data of 1580 patients with CDI,admitted to our hospital between 2008 to 2018.Patients were grouped based on the presence or absence of the appendix.The primary aim was to(1)assess all-cause mortality and(2)the severity of CDI.Severity was defined as per the Infectious Diseases Society of America criteria.Logistic regression,and propensity score analysis using inverse probability of treatment weights(IPTW)was performed.RESULTS Of the 1580 patients,12.5%had a history of appendectomy.There was no statistical difference in mortality between patients with a prior appendectomy or without(13.7%vs 14%,P=0.877).However,a history of appendectomy affected the severity of CDI[odds ratio(OR)=1.32,95%confidence interval:1.01-1.75].On IPTW,this association remained significant(OR=1.59,P<0.05).On multivariable toxic megacolon(OR=5.37,P<0.05)and colectomy(OR=2.77,P<0.05).CONCLUSION Prior appendectomy may affect the severity of CDI,development of toxic megacolon and the eventual need for colectomy.Since treatment of CDI is governed by its severity,stronger antibiotic regimens or earlier use of fecal microbiota transplant may be a viable option for patients with prior appendectomy. | Danial Haris Shaikh Harish Patel Rezwan Munshi Haozhe Sun Shehriyar Mehershahi Ahmed Baiomi Ahmed Alemam Usman Pirzada Iqra Nawaz Kamrun Naher Siddarth Hanumanthu Suresh Nayudu | 2021 | World Journal of Gastrointestinal Surgery2021，13，11： | 0 |
