ABSTRACT
Aims and Objective: High‑resolution esophageal manometry is the most important investigation for the
evaluation of patients with dysphagia and noncardiac chest pain (NCCP). Chicago Classification
(CC) utilizing an algorithmic approach in analyzing high‑resolution manometry has
been accepted worldwide, and an updated version, CC v3.0, of this classification has
been developed by the International high‑resolution manometry working Group in 2014.
Data on the spectrum of esophageal motility disorders in Indian population are scarce
as well as a newer version of CC has not been used to classify. The aim of our study
is to evaluate clinical presentation and manometric profile of patients with suspected
esophageal motility disorders using CC v3.0. Methodology: In this retrospective study, consecutive patients referred for esophageal manometry
at our center from 2010 to 2015 were included in the study. High‑resolution esophageal
manometry was performed with 22‑channel water‑perfusion system (MMS, The Netherlands).
Newer version of CC (CC v3.0) was used to classify motility disorders. Results: A total of 400 patients were included, with a mean age of 44 years and 67.5% were
males. Out of these, 60% (n = 240) patients presented with motor dysphagia while 40% (n = 160) had NCCP. Motility disorder was present in 50.5% (n = 202) of the patients while 49.5% (n = 198) patients had normal manometry. Disorders of esophagogastric junction outflow
were the predominant type of disorder, found in 33.75% (n = 135). About 14.25% (n = 57) of the patients had minor disorders of peristalsis while 5% (n = 20) of the patients had other major disorders of peristalsis. Achalasia was the
most common motility disorder present in 30% (n = 120) patients. Conclusion: Dysphagia was the most common esophageal symptom followed by NCCP in our series.
Achalasia was the most common esophageal motility disorder followed by fragmented
peristalsis.
