Figure 7 - Collis gastroplasty.

The Collis gastroplasty is an esophageal lengthening procedure that addresses a shortened esophagus. First, an anvil is passed alongside an esophageal dilator through the fundus (a). This guides an EEA stapler used to create a sealed "buttonhole" (b,c). Through this transgastric circular window, a linear cutting stapler is then placed and fired parallel to the esophageal dilator (d,e) essentially converting a cuff of proximal stomach into the distal esophagus. The wrap is then performed around the neoesophagus. EEA, end-to-end anastomotic stapling device; GIA, gastrointestinal anastomotic stapling device. (Source: Horvath KD, et al.
