Abstract
BACKGROUND AND AIMS
Peptic ulcer disease (PUD)-related gastric outlet obstruction (GOO) is known to respond favorably to endoscopic balloon dilation (EBD). However, data on efficacy of EBD for other etiologies of benign GOO are sparse. We aimed to compare the response of EBD among different etiologies of GOO.
METHODS
Records of all patients with benign GOO who underwent EBD at our tertiary-care center between January 1998 and December 2017 were analyzed. Dilation was done by using through-the-scope balloons. Procedural and clinical success of EBD was compared among different etiologies.
RESULTS
A total of 306 patients were evaluated, of whom 264 (mean [± standard deviation] [SD] age 37.89 ± 17.49 years; men 183, women 81) underwent dilation. Etiologically, caustic ingestion was the commonest cause of GOO (53.8%) followed by PUD (26.1%) and medication-induced (8.3%). Overall procedural and clinical success was achieved in 200 (75.7%) and 243 (92.04%) patients, respectively, requiring a mean (± SD) of 2.55 (2.8) and 5.37 (3.9) sessions, respectively. Caustic-induced GOO responded less favorably, requiring a higher number of dilation sessions and having more refractory strictures than other etiologies. Medication-induced GOO performed worse than PUD-related GOO. Of the 264 patients, 9 (3.4%) had perforations during EBD, 3 had contained leaks and were managed conservatively, and 6 underwent successful surgery.
CONCLUSION
EBD is successful in a majority of patients with benign GOO, with caustic-induced GOO and medication-induced GOO being more difficult than PUD-related GOO.
