Endoscopic resection of the pancreatic tail and subsequent wound healing mechanisms in a porcine model

Figure 4 Results of gastroscopy and endoscopic ultrasound at 7 d. A: Endoscopic ultrasonographic image obtained 7 d after surgery in experimental group one shows that a hyperechoic light mass near the pancreas is visible with the "comet tail sign.” B: Endoscopic ultrasonographic image obtained 7 d after surgery in experimental group two reveals effusions around the pancreas with a hyperechoic mass with the "comet tail sign”.
