Our objective is to describe the characteristic CT findings of gastrointestinal (GI) tract perforations at various levels of the gastrointestinal system. It is beneficial to localize the perforation site as well as to diagnose the presence of bowel perforation for planning the correct surgery. CT has been established as the most valuable imaging technique for identifying the presence, site and cause of the GI tract perforation. The amount and location of extraluminal free air usually differ among various perforation sites. Further, CT findings such as discontinuity of the bowel wall and concentrated free air bubbles in close proximity to the bowel wall can help predict the perforation site. Multidetector CT with the multiplanar reformation images has improved the accuracy of CT for predicting the perforation sites.

A 56 year-old man complaining of dry cough, dyspnea, chest pain, fever, and chills was admitted to the emergency room. The patient had a history of esophagectomy and esophagogastrostomy and subsequent radiotherapy because of an esophageal cancer. After the emergency echocardiography revealed a small amount of pericardial effusion and pneumopericardium. Upper GI contrast study showed a fistulous tract between the stomach and the pericardium, and an emergency operation was done under the diagnosis of gastropericardial fistula. The patient expired postoperative seven days later. Gastropericardial fistula caused by a peptic ulcer perforation after the esophagectomy and esophagogastrostomy operation is a very rare complication and brings forth a disastrous result. Early detection using the chest radiography, electrocardiogram, upper GI study, echocardiography and a review of physical examination, and an immediate treatment are therefore mandatory.

The gastric pedicle is commonly used for the reconstruction following the resection of esophageal cancer. We recently experienced a case in which gastric ulcer occurred eighteen months postoperatively. A 60 year-old man complaining of chest pain, dry cough, mild fever and chills was admitted to the emergency room. The patient had a history of esophagectomy and esophagogastrostomy because of esophageal cancer. Chest X-ray and CT scan showed pneumopericardium. Upper GI contrast study showed a fistulous tract between the stomach pedicle and the pericardium. Upper GI endoscopy showed beating heart through the fistulous opening. The patient expired with sepsis on the twenty second days after an emergent operation. Gastropericardial fistula caused by a peptic ulcer perforation after the esophgectomy and esophagogastrostomy operation is a very rare complication and brings a fatal result. Early detection using the chest radiography, electrocardiogram, echocardiography, upper GI study and physical examination, and an immediate treatment are therefore mandatory.
