Short benign ileocolonic anastomotic strictures - management with bi-flanged metal stents: Six case reports and review of literature

Table 1 Demographic characteristics, disease etiology, treatment characteristics, and other characteristics of luminal anastomotic benign stricture in patients who underwent bi-flanged metal stent (NAGI lumen-apposing metal stent) stent placement

Technical success was defined as successful placement of the bi-flanged metal stent across the stricture. Short-term clinical success was defined as symptom resolution with the indwelling stent (3 mo). Long-term clinical success was defined as symptom resolution at 7 mo after stent removal. BFMS: Bi-flanged metal stent; ICA: Ileocolonic anastomosis; L: Length; D: Diameter; F: Female; M: Male.
