Complication incidence after endoscopic ultrasound-guided fine needle biopsy: A single-center experience

Table 1 Distribution of complications according to the endoscopist’s years of experience

	Years of experience of the endoscopist			Significance1, P value
	0-3	3-5	More than 5
No complications	24 (30.0)	21 (26.3)	35 (43.8)	0.028
Complications	3 (37.5)	5 (62.5)	0

¹Analysis of variance. Most complications occurred in endoscopists with 3-5 years of experience (62.5%) while no complications were observed in those with more than 5 years of experience. Data are presented as n (%).

Table 2 Distribution of specific complications according to the endoscopist’s years of experience

Complications	Years of experience of the endoscopist			Significance, P value
	0-3	3-5	More than 5
Pancreatitis	0	1	0	0.299
Bleeding	1	2	0	0.260
Perforations	2	2	0	0.250
Infections	0	0	0	N/A
Lethality	0	0	0	N/A

While no complications were recorded in procedures performed by the most experienced endoscopist (with more than 5 years of experience), pancreatitis, bleeding, and perforations were observed among endoscopists with less experience. No infections or lethal outcomes occurred in the study population. Differences did not reach statistical significance. N/A: Not applicable.

Table 3 Summary of regression coefficients for predictors of complications

Variable	B (unstandardized)	Beta (standardized)	t	P value	Interpretation
CVD	0.208	0.327	2.504	0.014	Significant positive predictor
AH (hypertension)	-0.167	-0.291	-2.195	0.031	Significant negative predictor
Cancer	0.179	0.251	1.896	0.062	Trend-level significance
Previous surgery	-0.128	-0.212	-1.823	0.072	Near significance
Comorbidities (total)	0.026	0.026	0.218	0.828	Not significant

The table displays unstandardized (B) and standardized (Beta) coefficients, t-values, and P values for each variable. Cardiovascular disease and arterial hypertension were significant predictors (P < 0.05) while cancer and previous surgery showed trend-level or near-significant associations. Total comorbidity count was not a significant predictor. CVD: Cardiovascular disease; AH: Arterial hypertension.
