Endoscopic measurement of variceal diameter

Table 1 LDRf classification for gastrointestinal varices

Factors	Classification
Location(L)	Le: Esophageal varices
	Les: Varices in superior esophagus
	Lem: Varices in middle esophagus
	Lei: Varices in inferior esophagus
	Lg: Gastric varices
	Lgf: Varices in gastric fundus
	Lgb: Varices in gastric body
	Lga: Varices in gastric antrum
	Ld: Duodenal varices
	Ld1: Varices in the first part of duodenum
	Ld2: Varices in the second part of duodenum
	Ld1,2: Varices in the junction of the above two parts
	Lj: Jejunal varices. Li: Ileac varices.
	Lb:Biliary duct varices. Lc: Colonic varices.
	Lca: Varices in ascending colon Lct: Varices in transverse colon Lcd: Varices in descending colon Lcs: Varices in Sigmoid colon
	Lr: Rectal varices
Diameter (D)	D0: No varices.
	D0.3: The variceal diameter ≤ 0.3 cm.
	D1: The variceal diameter is from 0.4 cm to 1.0 cm;
	D1.5：The variceal diameter is from 1.1 cm to 1.5 cm;
	D2 : The variceal diameter is from 1.6 cm to 2.0 cm;
	D3 : The variceal diameter is from 2.1 cm to 3.0 cm;
Risk factors (Rf)	Rf0: RC-; no erosion, thrombus and active bleeding
	Rf1: RC+/HVPG > 12 mmHg; no erosion, thrombus and active bleeding
	Rf2: Erosion/thrombus/active bleeding, or lots of fresh blood excluded non-variceal bleeding

Table 2 Diameter and method chosen for treating varices

Maximum diameter (cm)	Appropriate treatment	Inappropriate treatment
No varices	Presentation after treatment
≤ 0.3	APC, laser, hemostatic clips	EVL, EVS and injection of tissue adhesives
0.4-1.0	EVL, EVS	APC, laser, hemostatic clips
1.1-1.5	EVL, EVS	APC, laser, hemostatic clips
1.6-2.0	EVS for esophageal varices, and injection of tissue adhesives for non-esophageal varices	EVL,APC, laser, hemostatic clips
2.1-3.0	EVS for esophageal varices, and injection of tissue adhesives for varices outside the cardia and esophagus	EVL, APC, laser, hemostatic clips

EVL: Endoscopic variceal ligation; EVS: Endoscopic variceal sclerotherapy; APC: Argon plasma coagulation.
