ABSTRACT Development of concurrent achalasia and chronic intestinal pseudo-obstruction (CIPO) is rare, although esophageal dysmotility is common in patients with CIPO and may suggest worse clinical outcomes. We present a case of a 63-year-old man with a 15-year history of CIPO who developed postprandial regurgitation, vomiting, and dysphagia and was diagnosed with achalasia through radiographic and endoscopic findings. This is only the third case in the reported literature that involves both conditions. Rather than representing 2 separate disorders, CIPO and achalasia may instead represent neurogenic variants of 1 underlying condition affecting the myenteric plexus.

Abstract Background and study aim The clinical impact of eosinophilic esophagitis (EoE) limited to the distal esophagus (Lim-EE) vs. diffuse involvement (Dif-EE) is unknown. This study compared clinical characteristics and outcomes of Lim-EE vs. Dif-EE. Patients and methods This retrospective, single-center study of patients with EoE between December 2011 and December 2019 evaluated treatment response based on repeated pathology and/or clinical improvement using comparative statistics. Results 479 patients were identified (126 Lim-EE, 353 Dif-EE). Lim-EE patients had a higher incidence of endoscopically identified esophagitis (23.0 % vs. 14.7 %; P = 0.04), were older (50.8 [SD 16.2] vs. 46.4 [SD 15.3] years; P = 0.007), and were more likely to present with iron deficiency anemia (5.6 % vs. 1.7 %; P = 0.05), dyspepsia (15.1 % vs. 8.8 %; P = 0.06) or for Barrett’s surveillance (10.3 % vs. 3.7 %; P = 0.02). Patients with Dif-EE presented more frequently with dysphagia (57.2 % vs. 45.2 %; P = 0.02). Both groups had similar proton pump inhibitor (87.2 % vs. 83.3 %; P = 0.37) and steroid (12.8 % vs. 21.4 %; P = 0.14) use. Patients with Lim-EE had a better clinicopathologic response (61.5 % vs. 44.8 %; P = 0.009). On multivariate analysis, EoE extent predicted treatment response with an odds ratio of 1.89 (95 % confidence interval 1.13–3.20; P = 0.02). However, treatment response based only on repeat biopsy results showed no statistical difference between Lim-EE (52.5 %) and Dif-EE (39.7 %; P = 0.15). Conclusions Lim-EE may represent a distinct phenotype separate from Dif-EE, with more overlap with gastroesophageal reflux disease and better treatment response.
