Endoscopic incisional therapy for benign esophageal strictures: Technique and results

Table 3 Various studies of incisional therapy in esophageal anastomotic stricture

Ref.	Type of stricture	No. of patients	Length of stricture	No. of pre-procedure dilatations1	Follow-up duration (mo)	Outcome of single session
Schubert et al[31], 2003	Treatment naive	15	6.1 mm	NA	23	No recurrence - 14/15 (93%)
			(3-10 mm)
Simmons et al[23], 2006	Refractory	9	--	6	3-14	No dysphagia - 4/9 (44.4%)
						No response - 1/9 (11%)
Hordijk et al[42], 2006	Refractory	20	< 1 cm - 12 cm	8	12	No dysphagia - 12/20 (60%)
			> 1 cm - 8 cm			Recurrence - 8/20 (40%)
						Treatment failure - 2/20 (10%)
2Hordijk et al[30], 2009	Treatment naive	EIT arm - 31	EIT arm - 1.35 cm	N/A	6	No difference in the success rate (80.6% vs 67.7%)
		SB arm - 31	SB arm - 0.55 cm (mean)			Treatment failure- EIT arm - 1; SB arm - 5
Lee et al[24], 2009	Treatment naive	24	< 1 cm - 21 cm	N/A	24	No recurrence - 21/24 (87.5%)
			> 1 cm - 3 cm			Restricture - 3/24 (12.5%)
Muto et al[25], 2012	Refractory	EIT - 32	≤ 5 mm - 49 mm	10	EIT - 14.8	Short term - 93.8% improvement
		EBD - 22	> 5 mm - 5 mm		EBD - 17.2	Long term - EIT better than EBD

¹Mean number of dilatations;

²Randomized prospective study. Treatment naïve: No previous dilatation; EIT: Endoscopic incisional therapy; SB: Savary bougienage; EBD: Endoscopic balloon dilatation; NA: Not applicable.
