Changing patterns of upper gastrointestinal bleeding over 23 years in Turkey

The Evolution of Gastrointestinal Bleeding: A Holistic Investigation of Global Outputs with Bibliometric Analysis

BACKGROUND

Gastrointestinal bleeding is one of the main presentations in emergency department admissions. Although there has been much improvement in prevention, diagnosis, and treatment recently, patients with GIB still have high morbidity and mortality. This study aimed to analyze the scientific articles on gastrointestinal bleeding published between 1980 and 2020 using statistical and bibliometric methods.

METHODS

Articles about gastrointestinal bleeding published between 1980 and 2020 were downloaded using the Web of Science data base and analyzed using statistical methods. Network visualization maps were used to identify trending topics. Correlation studies were evaluated using Spearman's correlation coefficient. Nonlinear regression analysis (exponential model) was used to estimate the number of articles in future years.

RESULTS

A total of 12 568 publications about gastrointestinal bleeding were found. Forty percent (n = 5033) of these publications were articles. The top 3 contributing countries to the literature were the United States of America (1646, 32.7%), the United Kingdom (433, 9%), and Germany (391, 7.7%). The top three journals with the most publications were Gastrointestinal Endoscopy (172), American Journal of Gastroenterology (165), and Digestive Diseases and Sciences (161). The effect of countries' gross domestic product levels on article productivity on gastrointestinal bleeding was significant (r = 0. 770, P < .001).

CONCLUSION

In this comprehensive study, a summary of 5033 articles was presented. We think that these detailed analyses will be a quick source to show the past, present, and future of this subject to those who are currently working on gastrointestinal bleeding.

EPIDEMIOLOGICAL PROFILE OF PATIENTS WITH NON-VARICEAL UPPER GASTROINTESTINAL BLEEDING SECONDARY TO PEPTIC DISEASE IN A TERTIARY REFERRAL BRAZILIAN HOSPITAL

BACKGROUND

Non-variceal upper gastrointestinal bleeding (NVUGIB) secondary to peptic ulcer disease is a medical digestive emergency and could be one of the most serious adverse drug reactions.

OBJECTIVE

To identify the frequency of diagnosis of NVUGIB secondary to peptic ulcer disease.

METHODS

Prospective and epidemiological study conducted in a tertiary referral Brazilian hospital, from July 2016 to December 2019. Upper gastrointestinal endoscopies (UGE) reports were evaluated daily. The diagnosis of NVUGIB secondary to peptic ulcer disease was defined through endoscopic findings of peptic ulcer and erosive gastric lesions, and clinical symptoms. The frequency of diagnosis of NVUGIB secondary to peptic ulcer disease was estimated through the ratio between the number of patients diagnosed and the number of patients underwent UGE in the same period.

RESULTS

A total of 2,779 endoscopic reports (2,503 patients) were evaluated, and 178 patients were eligible. The total frequency of diagnosis of NVUGIB secondary to peptic ulcer disease was 7.1%. The annual frequency of diagnosis between 2017 and 2019 ranged from 9.3% to 5.7%. Most patients were men (72.8%); self-declared white (71.8%); older people (56.7%); and, had no familiar or personal history of gastrointestinal diseases (60.1%). 90% of the patients had a peptic ulcer and melena (62.8%). Patients made chronic use of low-dose aspirin (29.3%), other antiplatelet agents (21.9%) and, oral anticoagulants (11.2%); and non-steroidal anti-inflammatories use in the week a prior to the onset of clinical symptoms (25.8%).

CONCLUSION

Seven in every 100 patients admitted and underwent UGE in a tertiary hospital were diagnosed with NVUGIB secondary to peptic ulcer disease.
