Morphological Characteristics of Biliary Strictures after Liver Transplantation Visualized Using SpyGlass™ Cholangioscopy

Table 1

Patient demographics and stricture morphological characteristics.

Case no.	Age (yr)	Sex	Ethnicity	BMI	Number of days after transplant to initial diagnosis	Morphological characteristics found using the SDDVS
1	71	M	Caucasian	23	384	Pinhole inflammatory fibrotic bile duct stricture; anastomosis with excess exudate; not amenable to stenting
2	62	F	Hispanic	25	56	Severely tight anastomotic stricture; pinhole orifice; amenable to stenting
3	64	M	Caucasian	31	25	Anastomotic bile duct stricture with persistent scarring
4	49	F	Caucasian	46	132	Scarring in the common bile duct but no narrowing; ostia of the hepatic ducts appeared to be normal
5	62	M	African American	30	71	August 28, 2018: web-like stricture at the anastomosis
						November 14, 2019: scarring in the anastomosis with a healthier mucosa in the proximal common bile duct
