Abstract Endoscopic Finding in Corrosive Ingestion Suphakan Techapongsatorn MD Pong Kanjanasuthirak MD Satit Srimantayamas MD Objective: To review the endoscopic finding within 48 hours after corrosive agent ingestion. Study design: Descriptive study. Subjects: One hundred and seventy-one patients were admitted in Department of Surgery, Bangkok Metropolitan Administration Medical College and Vajira Hospital during January 2001 to December 2005, from corrosive ingestion. Methods: Hospital records and endoscopic records were collected and analyzed. Main outcome measure: Endoscopic finding which were classified into 4 groups: no injury, 1st degree injury, 2nd degree injury and 3rd degree injury. The sites of injuries were divided into proximal esophagus, distal esophagus, proximal stomach (cardia, fundus and body), distal stomach (antrum and pylorus) and 1st part duodenum. Results: Demographic data showed that 124 patients (72.5%) were female and the average age was 26.2 years. Intentional ingestion was the cause in 166 patients (97.1%). Hydrochloric acid existing in hard surfaces Cleaner especially toilet and bowl cleaners was the most common corrosive agent in 126 patients (73.7%). The prevalence of injury in upper esophagus, lower esophagus, proximal stomach, distal stomach A and duodenum were 35.0%, 69.4%, 64.9%, 33.1% and 17.2% consecutively. Conclusion: These findings were different from the developed countries. In those countries, the most common corrosive agents were sodium hydroxide and potassium hydroxide that were strong bases in drain or pipe cleaner. Furthermore, lower esophagus especially esophagogastric junction and proximal stomach were the most susceptible sites of injuries. Then, management and teaching should be conversely from the developed countries as mentioned in many textbooks and journals.
