Table 3.

Outcome regarding hospital stay and re-interventions for bile duct problems. The WaS patients who were only treated with stents are divided in two groups, depending on if the patients received plastic or metallic stents (SEMS) in the perioperative time

	WaS plastic n = 25	WaS SEMS n = 23	DoB, n = 73	p-value
Primary hospital stay	7 (3–39)	7 (3–27)	14 (6–71)	<0.001
Total LoS#	18 (3–74)	15 (5–73)	24 (8–53)	0.001
Patients readmitted due to cholangitis/cholestasis	17	6	11 (15%)	0.001
Hospital days due to biliary related problems	10 (0–36)	4 (0–27)	4 (0–42)	0.001
ERC/PTC, post initial intervention	37	13	10	0.001

Italicized bold values indicates statistically significant changes.

Numbers presented as total numbers and median (range).

# Total LoS, includes primary LoS and total LoS of readmissions.

ERC, endoscopic retrograde cholangiography; PTC, percutaneous transhepatic cholangiography.
