The outcomes of endoscopic dilation for anastomotic stricture after laparoscopic gastric bypass in selected series are shown in Table 11.1. The incidence of stricture in these selected series ranged between 5.4 and 23%. Successful endoscopic dilation is defined as complete resolution of obstructive symptoms and no recurrence of symptoms in the follow-up period. Nguyen et al. reported that 83% of patients who underwent endoscopic dilation had complete resolution of symptoms after a single dilation, 14% of patients required a second dilation, only 3% of patients required a third dilation, and surgical revision of the gastrojejunostomy was not necessary in any patient [6]. Other investigators have reported similar success [10–17]. Barba and colleagues reported that 67% of patients who developed anastomotic stricture after RYGB required a single dilation, and 30% required a second dilation; there were no complications in their series [12]. Overall, endoscopic dilation for stricture is highly successful in 95–100% of patients. Resolution of obstructive symptoms after a single endoscopic dilation is variable, ranging between 28 and 86%. In two of nine series, the Savary-Gilliard dilator was used. Fernandez-Esparrach et al. reported the outcomes of endoscopic dilation using the Savary-Gilliard bougie in 24 patients with anastomotic stricture and found that 46% of patients required a single dilation, while 50% of patients required a second dilation [15].
