Abstract

|
Picosulfate solution is widely used as a small volume bowel cleansing agent and is considered to be effective and relatively safe. A case of a 75-year-old woman ingested picosulfate powder and drank a small volume of water, subsequently experienced severe burning pain in the chest. Endoscopy was performed and showed a submucosal hemorrhage and exudative ulcers at the mid to lower esophagus. At 2 weeks, her symptoms improved with conservative treatment. However, liquid food dysphagia developed 11 weeks after ingestion. A follow-up endoscopy revealed multiple esophageal strictures, which were treated with a fully covered metal stent and esophageal balloon dilation. Consequently, the esophageal strictures improved after one year. As this case demonstrates, detailed information about picosulfate powder ingestion after dissolving it in more than 200 mL of water should be presented to patients to avoid esophageal injury.
