A PROGRESSIVE OBSERVATIONAL STUDY OF CORRELATION BETWEEN DISTANCE OF OESOPHAGOGASTRIC JUNCTION FROM UPPER CENTRAL INCISORS AND HEIGHT OF A PERSON OF INDIAN ORIGIN.

Abstract

The distance of oesophagogastric junction from upper central incisors is clinically important in various procedures like oesophageal manometry and 24 hours pH monitoring in patients with clinical features suggestive of gastroesophageal reux disease and achalasia cardia. The various anatomical studies done to determine distance of oesophagogastric junction from upper central incisors were based on cadaveric dissection. There is signicant variability in the distance of oesophagogastric junction from upper central incisors derived from the cadaveric dissections across age, sex and race. Variability is also seen between cadaveric distance of oesophagogastric junction from upper central incisors and the distances measured on upper gastro-intestinal endoscopy. Many studies have tried to estimate length of oesophagus using various external body parameters and most have concluded that the height of the person is the best parameter to estimate distance of oesophagogastric junction from upper central incisors before doing any interventional procedure. This study was done to nd a correlation between height of the person and the distance of oesophagogastric junction from upper central incisors, as derived on upper gastrointestinal endoscopy, in an Indian population.
