Gastric outlet obstruction is a significant complication, but the insightful physician will be able to identify the problem and treat it within moments. Obstruction is caused by the retention balloon blocking the pylorus either because the tube migrated to the pylorus in the case of a standard G‐tube or because the balloon is overfilled in the case of a low‐profile button. Patients will present with abdominal pain, nausea, feeding intolerance, and nonbilious emesis. A contrast‐enhanced radiographic study that shows dye filling the small intestine but sparing the stomach confirms the diagnosis (Figure 1.5). Treatment is relatively anticlimactic and includes deflating the internal balloon, repositioning it away from the pylorus and reinflating it or simply reducing the amount of fluid in the retention balloon itself.
