“…This test uses impedance planimetry to calculate the esophageal lumen dimensions and distensibility. Usually, it is used to corroborate findings from HRM and/or barium swallow and assess the effect of treatment [4]. This is a relatively new technology, complimentary to other tests, and its usefulness is not fully determined.…”

Purpose of review To compare different therapeutic modalities and determine their role in the treatment of esophageal achalasia. Recent findings The last 3 decades have seen a significant improvement in the diagnosis and treatment of esophageal achalasia. Conventional manometry has been replaced by high-resolution manometry, which has determined a more precise classification of achalasia in three subtypes, with important treatment implications. Therapy, while still palliative, has evolved tremendously. While pneumatic dilatation was for a long time the main choice of treatment, this approach slowly changed at the beginning of the nineties when minimally invasive surgery was adopted, initially thoracoscopically and then laparoscopically with the addition of partial fundoplication. And in 2010, the first report of a new endoscopic technique – peroral endoscopic myotomy (POEM) – was published, revamping the interest in the endoscopic treatment of achalasia. Summary This review focuses particularly on the comparison of POEM and laparoscopic Heller myotomy (LHM) with partial fundoplication as primary treatment modality for esophageal achalasia. Based on the available data, we believe that LHM with partial fundoplication should be the primary treatment modality in most patients. POEM should be selected when surgical expertise is not available, for type III achalasia, for the treatment of recurrent symptoms, and for patients who had prior abdominal operations that would make LHM challenging and unsafe.

BackgroundThe functional lumen imaging probe (FLIP) has proven to be a versatile device for diagnosing esophageal motility disorders and estimating esophageal wall compliance, but there is a lack of viable software for quantitative assessment of FLIP measurements.MethodsA Python‐based web framework was developed for a unified assessment of FLIP measurements including clinical metrics such as esophagogastric junction (EGJ) distensibility index (DI), maximum EGJ opening diameter, mechanics‐based metrics for estimating strength, and effectiveness of contractions, such as contraction power and displaced volume, and machine learning‐based clustering and predictive algorithms such as the virtual disease landscape (VDL) and EGJ obstruction probability. The clinical and VDL probability metrics were then validated using FLIP data from 121 subjects constituting different categories of EGJ opening which were diagnosed by expert clinicians.ResultsThe clinical metrics estimated by the framework matched the manual diagnosis of the clinicians. Misclassifications were minimal and were mostly between neighboring groups, that is, normal and borderline normal or borderline normal and borderline reduced EGJ opening. Similar results were also obtained for the VDL probability metrics. The misclassifications were further analyzed by clinicians and approved.ConclusionThe FLIP web framework was developed and validated to reliably estimate various clinical, mechanical, and machine learning‐based metrics for diagnosing esophageal motility disorders.
