Definition of severity of the strictures

	Width (mm)	Length (cm)	Proximal dilatation	Intra-stricture angles
Mild	5 or more	Up to 1	None	None
Moderate	3–5	1–2	Present	One
Severe	Up to 3	2 or more	Severe	Two or more

Strictures were classified according to their severity. The categories—mild, moderate, or severe -were based on evaluating four key characteristics: the width and length of the stricture, the extent of dilatation proximal to the stricture, and the number of intra-stricture angles. The presence of any one of these characteristics was sufficient to categorize the stricture into a specific severity level
