Fluoroscopic Balloon Dilation for Treating Postoperative Nonanastomotic Strictures in the Proximal Small Bowel: A 15-Year Single-Institution Experience.

PURPOSE: To evaluate safety and effectiveness of fluoroscopic balloon dilation (FBD) for treating postoperative nonanastomotic strictures in proximal small bowel.

MATERIALS AND METHODS: Data of 44 patients (26 men and 18 women; mean age, 53.7 y ± 13.0) treated with FBD for postoperative nonanastomotic strictures in the proximal small bowel between January 2000 and February 2016 were retrospectively reviewed. Site of stricture was located in the first portion of duodenum in 8 (18.2%) patients, second portion of duodenum in 8 (18.2%) patients, third portion of duodenum in 1 (2.3%) patient, fourth portion of duodenum in 1 (2.3%) patient, and proximal jejunum in 26 (59.1%) patients. Mean distance between the most anal-side lesion and the oral cavity was 63.9 cm ± 15.0.

RESULTS: Technical success was achieved in 39 (88.6%) patients. Mean stricture length was 3.0 cm ± 1.8. Technical failure because of inability to negotiate the guide wire through the stricture occurred in 5 (13.6%) patients. Complete resolution of obstructive symptoms and resumption of oral intake of soft or solid food within 3 days occurred in 34 patients after 1 (n = 32) or 2 (n = 2) FBD sessions, rendering a clinical success rate of 87.2%. There were no major complications directly related to FBD. Median follow-up period was 1,406 days (interquartile range, 594-2,236 d). Nine (26.5%) patients had recurrence within a median 47 days (interquartile range, 20-212 d).

CONCLUSIONS: FBD may be safe and effective for treating postoperative nonanastomotic strictures in the proximal small bowel.
