Does endoscopic intervention prevent subsequent gastrointestinal bleeding in patients with left ventricular assist devices? A retrospective study

Table 4 Outcomes for gastrointestinal bleeding encounters with endoscopic intervention vs none gastrointestinal bleeding

Factor	Endoscopic intervention	No endoscopic intervention	P value
Median number of days to subsequent GIB (IQR)	113 (15-302)	72 (24-178)	0.51
	n = 44	n = 97
Proportion with subsequent GIB within 30 days	29.5%	34.0%	0.37
	n = 44	n = 97
Median length of stay in days for those with GIB on admission (IQR)	12 (10-23)	12 (8-21)	0.58
	n = 31	n = 86

The following statistical tests were utilized: Wilcoxon rank-sum test [days to subsequent gastrointestinal bleeding (GIB), length of stay], and Fisher’s exact test (proportion with subsequent GIB within 30 d). GIB: Gastrointestinal bleeding; IQR: Interquartile range.
