- W2084995957 abstract "A 29-year-old man with previous neonatal meningitis and spastic quadriplegia required feeding by percutaneous endoscopic gastrostomy (PEG) because of a poor oral intake. As a standard PEG placement was impossible due to severe postural contractures and a large hiatus hernia, a 20F PEG tube was placed using a combined endoscopic and radiological approach. As the stomach was largely intrathoracic, it was inadvertently accessed via the left 11th intercostal space and placement was initially complicated by a pneumothorax and pneumoperitoneum. The PEG tube functioned well for 6 months but, thereafter, the patient became distressed during feeding. A PEG tubogram and endoscopy confirmed migration of the bumper out of the stomach but, with traction to remove the tube, it became disconnected from the bumper. To avoid a thoracotomy, the bumper was left in situ between the gastric wall and ribs and a new PEG was inserted through the existing tract. Seven months later, use of the second PEG also became difficult. At gastroscopy, the buried PEG appeared as a protrusion in the gastric body. A computed tomography scan was performed (Fig. 1). Endoscopic removal of the PEG involved an incision of the overlying gastric mucosa with a needle-knife papillotome, dilatation of the tract using an 18 mm wire-guided dilating balloon and extraction of the bumpers through the stomach. The bumper from the initial PEG was found attached to the second PEG tube (Fig. 2). A 20F Ballard gastrostomy tube with an internal balloon was then positioned over a wire through the existing tract. The patient has remained well on follow-up for 2 years. Migration of the internal flange or PEG bumper out of the stomach is termed the buried bumper syndrome. This is usually due to excessive external traction on the PEG tube from a tight external flange that causes the bumper to erode through the gastric wall. In our case, rib fixation and continual respiratory movements seems likely to have contributed to the two episodes of buried bumper syndrome. Typical methods to remove buried bumpers involve the use of snares, grasping forceps, Savary dilators and modified PEG tube sets. However, in the above patient, these approaches were unlikely to have been successful and surgery would have required a thoracotomy. The combination of needle-knife incision of the gastric wall to expose the buried bumpers and balloon dilatation to enlarge the tract and pull the bumpers into the stomach does not appear to have been described previously.
