Gastrografin swallow test (GST). (a) Normal 2nd POD GST: tightness of the linear suture is confirmed, and presence of gastric leak is excluded. (b) 2nd POD GST of our early complicated patient: it clearly shows the gastric leak (white arrow) close to the gastroesophageal junction near the angle of His.

GST (2nd POD) revealed GL of gastroesophageal junction (Figure 1(b), further investigated with contrast-enhanced CT scan (CT-Figures 2(a) and 2(b); 3rd POD) and endoscopic control (Figure 3(a)).
The early complicated patient, shown on axial (a) and coronal (b) CT-scan during the portal phase. CT images show the GL and corresponding collection on the 2nd POD (Figure 2(a), white arrow). The gastric fistula linking the stomach and enhanced collection (white arrow) are shown.

GST (2nd POD) revealed GL of gastroesophageal junction (Figure 1(b), further investigated with contrast-enhanced CT scan (CT-Figures 2(a) and 2(b); 3rd POD) and endoscopic control (Figure 3(a)).
Endoscopic views of an early complicated patient. The GL documented with GST and CT scans now appears evident at endoscopic inspection ((a)) (with arrow). A large walled-off perifistular collection suspected at GST (Figure 1(b)) is confirmed at the endoscopic inspection (b). (c) EDPC positioned. (d) Endoscopic control at the 28th POD: internal drainage acts like a foreign body and promotes the physiological re-epithelization of the leak (white arrow).
