Conservative management for iatrogenic gastric perforation by transesophageal echocardiography

BACKGROUND: Though several cases of upper gastrointestinal tract injury caused by transesophageal echocardiography (TEE) have been reported, gastric perforation is very rare. Herein, we report the case of TEE-associated gastric perforation that was successfully treated conservatively. CASE PRESENTATION: An 82-year-old man underwent mitral valve repair. Postoperative esophagogastroduodenoscopy and computed tomography revealed gastric perforation. Surgical treatment was initially considered, but conservative management was selected to avoid increasing operative stress, to minimize the need for total gastrectomy (including the lower esophagus), and to minimize the risk of a potential intraperitoneal infection spreading to the thoracic cavity. CONCLUSION: Conservative management of gastric perforation can be successful even when the perforation is recognized later than 12 h following the event, provided that there are no abdominal symptoms and no signs of peritoneal effusion or sepsis. Our experience suggests that conservative management is a feasible option for treating TEE-associated gastric perforation in appropriately selected cases.
