ABSTRACT
BACKGROUND AND AIMS:
Treatment options for nonachalasia obstructive disorders of the esophagogastric junction (EGJ) are limited. The aim of this study was to assess the treatment efficacy of pneumatic dilation (PD) for the disorders of EGJ outflow obstruction (EGJOO) and postfundoplication EGJ obstruction (PF-EGJO) and to assess attitudes regarding training in PD.METHODS:
This was a 2-part study. The main study was a prospective, single-center study comparing treatment outcomes after PD in patients with EGJOO and PF-EGJO, defined using manometry criteria, versus achalasia. Treatment success was defined as a post-PD Eckardt score (ES) of ≤2 at the longest duration of follow-up available. In a substudy, a 2-question survey was sent to 78 advanced endoscopy fellowship sites in the United States regarding training in PD.RESULTS:
Of the 58% of respondents to the advanced endoscopy program director survey, two-thirds reported no training in PD at their program. The primary rationale cited was lack of a clinical need for PD. Sixty-one patients (15 achalasia, 32 EGJOO, and 14 PF-EGJO) were included in the main study with outcomes available at a mean follow-up of 8.8 months. Overall, mean ES decreased from 6.30 to 2.89 (P < .0001), and a mean percentage of improvement in symptoms reported by patients was 55.3%. ES ≤2 was achieved by 33 of 61 patients (54.1%).CONCLUSIONS:
PD is an effective treatment for the nonachalasia obstructive disorders of the EGJ. There may be a current gap in training and technical expertise in PD.
