The overuse of endoscopy has negative effects on the quality of healthcare and pressurises endoscopy services. It also results in the complications. These complications include pneumoperitoneum, pneumomediastinum and subcutaneous pneumomediastinum. However, it is worth noting that these complications rarely occur during endoscopy of the upper GI tract. These complications, when they occur, indicate perforation of the retroperitoneal space or peritoneal cavity. In this article, we discuss a case of pneumoperitoneum, pneumomediastinum and subcutaneous emphysema after upper GI endoscopy.
