Table 3 Practical considerations
Predictors favoring successful dilation[11,22-25]Symptomatic predominantly fibrotic stricture
Short (≤ 5 cm) stricture
Single straight stricture
Stricture distal to the duodenum
Anastomotic stricture more favorable than de novo stricture
First dilation
Lack of a superimposed process contributing to symptoms (e.g., SIBO or IBS)
Risk factors for complications[22-25]Predominantly inflammatory stricture without medical optimization
Stricture greater than 5 cm
Multiple small bowel strictures
Strictures caused by extrinsic compression (e.g., adhesions)
Fistulization within 5 cm of the area to be dilated
Adjacent perforation or intra-abdominal collection
Complete small bowel obstruction
Tortuous or tethered small bowel or significant stricture angulation
Duodenal stricture
1Short term outcome[15,18]85%-95% (technical success), 70%-80% (clinical response)
2Long term outcome[15,18]32% (year 1 post dilation), 80% (year 5 post dilation)
3Complication rate[25,45]1%-4%
