Background: The relationship between living conditions in urban and rural areas during childhood and subsequent inflammatory bowel disease (IBD) remains controversial.
Aim: To explore the association between environmental exposures early in life and the subsequent risk of IBD.
Methods: Literature searches were conducted in the following databases: PubMed, EMBASE, and Conference Proceedings Citation Index. Studies were analyzed separately using rate ratios (RRs) or odds ratios (ORs) with 95% confidence intervals.
Results: The search strategy identified 15 studies. Of these, 9 studies explored the association between urban exposure during childhood and ulcerative colitis (UC), and 12 and 4 studies explored this relationship with Crohn’s disease (CD) and IBD, respectively. A meta-analysis showed that the pooled ORs estimated for the case–control studies of UC, CD, and IBD were 1.16 (0.83, 1.61), 1.45 (1.45, 1.85), and 1.34 (1.11, 1.62), respectively. The pooled RR estimated for the cohort studies of CD and IBD was 1.48 (1.17, 1.87). The stratified analysis and meta-regression showed significant relationships between CD and living conditions in case–control studies published during 2010–2017 and in non-European countries (P < 0.05).
Conclusions: Living conditions during childhood are positively associated with the subsequent development of IBD. Urban living environment is more common among those with CD than UC. 相似文献
目的:探讨管状吻合器在腹腔镜Miles术中乙状结肠腹膜外造瘘中的临床应用.方法:回顾性分析2012-01/2014-01南昌大学第一附属医院38例行腹腔镜辅助直肠癌经腹会阴联合切除术(Miles)中采用管状吻合器行乙状结肠腹膜外造瘘患者临床资料术中将造口用乙状结肠从腹膜外拖出,于断端置入吻合器底钉座,同时腹壁行荷包缝合,进行吻合完成乙状结肠腹膜外造瘘观察并分析本术式的安全性、术中术后的造口相关并发症以及术后造口功能的恢复情况.结果:38例均获得随访,术后中位随访时间18 m o(8-32mo),术后1例患者造瘘口轻度凹陷,1例患者术后早期出现造口结肠黏膜局部缺血坏死,均未予特殊处理,1例患者发生梗阻,经再次手术解除梗阻后治愈,无脱垂、造瘘口旁疝等其他远期并发症.31例(81.6%)的患者术后2-3 mo起开始出现排便反射,具有一定的控便功能,人工肛门功能综合评价较高,易于护理,患者心理障碍发生率低.结论:管状吻合器在腹腔镜Miles术中乙状结肠腹膜外造瘘中的应用安全、可靠,操作简单,术后并发症少,且美观、易于护理,具有临床应用价值. 相似文献
