Detail correction for Gross classification of esophageal atresia based on 434 cases in China

Since Vogt[1] recognized and classified the types of anomalies in 1929, many other classification systems have been proposed, including the Ladd, Gross, Swenson, and Kluth classification systems. [...]the illustration of the anatomical pattern of different types of EA/TEF was modified by close comparison with the original images from 434 patients with EA/TEF. According to our study, whether the proximal esophageal pouch is dilated may provide physicians with valuable insight into the diagnosis. [...]an accurate depiction of the gap length reveals why gastrotomy is preferred over primary anastomosis in type A and B patients. Because the distal esophageal remnant barely extends beyond the hiatus of the diaphragm, the gap between the pouches is too wide to be covered by one-stage reconstruction.
