Gastric suction tube with pressure necrosis in the esophagus
Pressure necrosis Pressure necrosis
Foreign bodies left in the esophagus for a considerable length of time can cause damage to the esophageal mucosa. The example shows the endoscopic view of extensive pressure necrosis located precardial and in the lower third of the esophagus (left picture). They are caused by a gastric suction tube for decompensated pyloric stenosis. These ulcerations occured after 48 hours of gastric suction and show a complete healing 10 days thereafter (right picture). The tube was made of polyvenylchloride. In our experience silicon tubes cause less damage to the esophageal mucosa and thus are more suitable for continuous gastric suction or enteral tube feeding. Tubes should be removed as early as possible or avoided in the first place. PEG is a good alternative for continuous enteral feeding.
