ARTICLE HIGHLIGHTS
Research background

Gastrointestinal hemorrhage (GIH) is a common complication with gastrointestinal cancers (GIC).

Research motivation

There is no comprehensive research that examines GIH in different types of GIC. Furthermore, endoscopic therapy is insufficiently studied in this setting.

Research objectives

We aim to study the prevalence, predictors, and interventions of GIH based on the anatomical location of GIC.

Research methods

This is a retrospective analysis of the 2016-2018 National Inpatient Sample database, the largest inpatient care database in the United States. Adult inpatients were evaluated for the prevalence and predictors of GIH in the setting of GIC. In addition, inpatient mortality was compared between patients who underwent or did not undergo endoscopy.

Research results

The highest to lowest GIH rates are listed in the following order: stomach cancer (15.7%), liver cancer (13.0%), small bowel cancer (12.7%), esophageal cancer (9.1%), colorectal cancer (9.1%), pancreatic cancer (7.2%), bile duct cancer (6.0%), and gallbladder cancer (5.1%). Inpatient mortality was significantly lower in patients who underwent endoscopy compared to no endoscopy [5.5% vs 14.9%, OR = 0.42 (0.38-0.46)], P < 0.001).

Research conclusions

The prevalence of GIH in patients with GIC varies significantly based on the tumor’s anatomical location. Endoscopy appears to be associated with a substantial reduction in inpatient mortality and should be offered to GIC patients with GIH.

Research perspectives

Future studies, prospective and randomized trials, would help confirm the effectiveness of endoscopic therapy for GIH in patients with GIC.
