INTRODUCTION AND IMPORTANCE: Esophageal rupture and perforation are serious complications of blunt abdominal trauma. Early diagnosis and intervention is key for patient survival. Studies have reported that mortality of patients with esophageal perforation can be as high as 20-40 % (Schweigert et al., 2016; Deng et al., 2021 [1, 2]). We present a patient with suspected esophageal perforation after a blunt trauma identified by esophagogastroduodenoscopy (EGD) as the presence of a second gastroesophageal lumen concerning for esophagogastric fistula. CASE PRESENTATION: Our patient is a 17-year-old male with no past medical history who was brought in from an outside facility status post electric bike accident. CT imaging from an outside hospital showed concern for possible esophageal rupture. On arrival, he was in no acute distress. Patient underwent a fluoroscopy upper GI series which showed extravasation of fluid outside the lumen, indicating an esophageal injury. Patient was evaluated by Gastroenterology and Cardiothoracic surgery, who agreed on an empiric course of piperacillin/tazobactam and fluconazole for prophylaxis in the setting of suspected esophageal rupture. Patient underwent an esophagram with EGD which demonstrated a 2nd false lumen from 40 to 45 cm. This appeared to be from incomplete avulsion of the submucosal space. No contrast extravasation was seen with the esophagram. CLINICAL DISCUSSION: To date, there has been no published case of trauma induced formation of a double lumen esophagus. Our patient presented with no previous history to suggest chronic or congenital double lumen of the esophagus. CONCLUSION: When considering esophageal rupture, the possibility of the formation of an esophago-gastric fistula should be considered via external traumatic insult.

Unintentional injuries are one of the leading causes of death in Americans. A large proportion of these deaths are attributable to accidental drownings and falls, both of which oftentimes take place in or around swimming pools and swimming pool-related apparatuses such as diving boards. The American Academy of Family Physicians (AAFP) has reported drowning incidents as the most common injury-related cause of death in children ages one to four years. Although the AAFP has outlined steps to take to prevent drownings, there has not been a current large-scale study illustrating the effectiveness of these strategies with regard to their effect on the prevalence of swimming pool drowning cases in the last 10 years. Thus, we aim to utilize the National Electronic Injury Surveillance System (NEISS) database to uncover these rates, which can ultimately help aid in the reevaluation of current recommended guidelines.
