These are distinguished by the presence of ≥20% hypercontractile (HE) versus premature (DES) swallows. Esophagogastric junction outflow obstruction (EGJOO) is characterized by preserved peristalsis but impaired lower esophageal sphincter (LES) relaxation. We present a unique case of HE with concomitant EGJOO on high-resolution manometry (HRM), exhibiting endoscopic features typical of DES.
Case Description/
Methods: A 70-year-old female with a history of Parkinson’s disease and diabetes mellitus presented with a three-month history of intermittent solid food dysphagia and heartburn. Initial barium esophagram revealed tertiary contractions in the mid to distal esophagus (Figure 1A). Esophagogastroduodenoscopy (EGD) with pH monitoring showed no structural abnormalities and acid exposure was not correlated with symptoms. A subsequent EGD with HRM revealed elevated LES pressures, 40% hypercontractile swallows, and abnormal LES relaxation (Figure 1B).
To further evaluate her esophageal dysmotility, a repeat EGD with Endoflip panometry was performed, demonstrating esophageal spasticity and multiple extra peristaltic contractions producing a classic “corkscrew” (Figure 2). The patient was diagnosed with HE with EGJOO and initiated on calcium channel blockers. She was referred for per-oral endoscopic myotomy (POEM) for further management. Discussion: Esophageal motility disorders often present with overlapping symptoms including chest pain, regurgitation and dysphagia. While DES typically produces a “corkscrew” appearance on both barium esophagram and EGD, these findings are uncommon in HE. Interestingly, our patient’s barium study was non-specific, but endoscopic imaging revealed a striking corkscrew morphology, more characteristic of DES. HE with EGJOO is increasingly recognized as a distinct but rare manometric pattern with an unclear pathophysiologic basis. HRM and EndoFLIP remain essential tools in confirming diagnosis and guiding therapy. This case highlights the diagnostic complexity and clinical overlap between HE, DES and EGJOO, emphasizing the importance of integrating clinical, endoscopic, and manometric findings to tailor management effectively.
