To determine the proportion of abstracts presented at the Congreso Peruano de Gastroenterología (the major Peruvian gastroenterological scientific meeting), that had been published in scientific journals, the date of publication and its associated factors.
MATERIALS & METHODS: Longitudinal retrospective and analytic study; the publicationrate of all the abstracts presented in the biennial Congreso Peruano de Gastroenterología between 1998 and 2008 was assessed. Google Scholar engine was used. The searching strategy performed included: ("Study location" AND "population studied" AND "main outcome") AND (autor:First OR autor:Second OR autor:Last). Logistic regression was used, considering p<0.05 statistically significant.
Publication rate was 8.2% (34/217), statistically significant differences were found among meeting years (p<0.001). There were also differences between study design, objectives (more in analytic studies) and measurement (more in longitudinal studies (p<0.001). 82.4% were published in the Revista de Gastroenterología del Perú. The median time for publication was 10.8±10.4 months; this variable and the meeting year, study type, journal of publication or accordance between the abstract and publication characteristic showed no statistical differences. The mean authors' number was 5.02±2.4; analytic studies have less authors than the descriptive ones (3.6 vs 6.1; p=0.012).
The Congreso Peruano de Gastroenterología presents a low publication rate of the abstracts presented, which can be used as a quality indicator of the abstracts and the reviewing process.
确定在秘鲁胃肠病学大会（秘鲁主要的胃肠病学科学会议）上发表的摘要中，已在科学期刊上发表的比例、发表日期及其相关因素。
纵向回顾性分析研究；评估了1998年至2008年每两年一届的秘鲁胃肠病学大会上发表的所有摘要的发表率。使用谷歌学术引擎。执行的检索策略包括：（“研究地点”且“研究人群”且“主要结果”）且（作者：第一作者或第二作者或最后一作者）。采用逻辑回归分析，以p<0.05为具有统计学显著性。
发表率为8.2%（34/217），各会议年份之间存在统计学显著差异（p<0.001）。研究设计、研究目的（分析性研究中更多）和测量方法（纵向研究中更多）之间也存在差异（p<0.001）。82.4%发表在《秘鲁胃肠病学杂志》上。发表的中位时间为10.8±10.4个月；该变量与会议年份、研究类型、发表期刊或摘要与发表特征之间的一致性均无统计学差异。作者平均人数为5.02±2.4；分析性研究的作者比描述性研究的作者少（3.6对6.1；p=0.012）。
秘鲁胃肠病学大会上发表的摘要发表率较低，这可作为摘要及评审过程质量的一个指标。
