Received: Accepted: Abstract Intramural esophageal hematomas are rare with few cases reported in the literature. Risk factors that affect the incidence of this condition include nausea and vomiting, but its most common clinical presentation is the triad of hematemesis, dysphagia and chest pain. Conservative treatment is best in most cases. We present our experience in 7 cases collected during the last 8 years in which you can see the entire spectrum of the disease from submucosal dissection to perforation of the esophagus. Key words Perforation, esophageal dissection, esophageal hematoma. Introduction Intramural esophageal hematomas occur infrequently and are characterized by hemorrhaging or bleeding contained between the mucosa and the muscular layers of the esophagus. This condition can lead to dissection and perforation of the submucosa and usually appears to be due to a sudden increase of intrathoracic pressure after situations such as trauma, vomiting, coughing and retching (1). Risk factors such as esophageal varices, esophageal ulcers and coagulopathy also favor this condition. Its most frequent clinical appearance is the triad of hematemesis, dysphagia and chest pain (2, 3). Intramural esophageal hematomas can be diagnosed radiologically, but need upper endoscopy for confirmation (4-6). This condition s development is often benign with treatment limited to clinical observation. Nonetheless, when there are complications like esophageal perforation, severe bleeding, or obstruction of the esophagus and the airways, endoscopic intervention or surgery become necessary (7). In this article we review our experience in 7 cases recorded from among the approximately 40,000 endoscopies done from 2002 to These cases cover several endoscopic diagnoses including hematoma, dissection and perforation of the mucosa (See Table 1). Case presentation Case 1 A 65-year-old female patient with a history of high blood pressure was admitted after two days of emetic episodes related to food contents followed by hematemesis with no hemodynamic stability. Upper endoscopy showed a hematoma in the proximal third of esophagus toward the right wall. The hematoma dried the mucosa and extended into the distal third of the esophagus (Figure 1). Patient was treatment by eliminating oral feeding and was observed. Endoscopic follow-up 48 hours later showed improvement of the hematoma and healing of the mucosa (Figure 2). The patient recovered successfully and was discharged after three days Asociaciones Colombianas de Gastroenterología, Endoscopia digestiva, Coloproctología y Hepatología 123

Case 2 A 70-year-old female patient with a history of heart failure was admitted following 2 days in which she felt dysphagia, chest pain and the presence of a foreign body at the hypopharynx. Upper endoscopy showed a chicken bone in the proximal esophagus and hematoma on the right esophageal wall. The foreign object was removed successfully through the mouth followed by observation of the patient who evolved without complications. She was discharged on the third day. Case 3 A 72-year old female patient with a history of heart failure was admitted after eight days of chest pain and hematemesis.

Upper endoscopy showed longitudinal tearing of the mucosa from the proximal third of the esophagus toward the right wall all the way to the distal third.

They were negative for any malignancy. Patient was observed and progressed favorably. Case 4 A 66-year-old female patient with a history of high blood pressure was admitted following 2 days of chest pain, dysphagia and melena. Upper endoscopy showed longitudinal tearing of the mucosa from the proximal third of the esophagus toward the right wall all the way to the distal third. Patient was observed, progressed satisfactorily, and was discharged on the third day. Case 5 A 72-year-old female patient with an old stroke noted in her medical history was admitted following several emetic episodes the day before which had been followed by hematemesis and anemia. Upper endoscopy showed dissection of the sub mucosa in the proximal third of the esophagus toward the right wall (Figure 3). A large hematoma could also be observed extending from the middle third of the esophagus toward the left wall. It dried the wall all the way to the distal third (Figure 4). The patient was hospitalized and esophagography ruled out perforation (Figure 5). Endoscopic followup 48 hours later showed drainage of the hematoma in the light of the esophagus and submucosa dissection (Figure 6). The patient s symptoms resolved, she progressed successfully, and she was discharged on the fourth day. Figure 4. Hematoma and esophageal submucosa dissection. Figure 5.

A 76-year-old female patient with a history of chronic obstructive pulmonary disease (COPD) was admitted following 3 days of coughing and dyspnea. She was taken to the ICU after suffering hypoxemic respiratory failure and a massive right pleural effusion. A thoracotomy was performed. 24 hours later the patient presented hematemesis. Upper endoscopy was performed and showed a large perforation with necrotic tissue in the middle third of the esophagus towards the right wall (Figure 7). Patient was surgically treated but died the next day. Intramural esophageal hematoma: Dissection of the perforation 125

Esophageal perforation. Case 7 An 82-year-old female patient who had been hospitalized due to a stroke and who was being fed through a nasogastric tube presented melena and bloody drainage through the catheter. An upper endoscopy showed multiple blood clots from the distal third of the esophagus that prevented evaluation of the mucosa. The feeding tube was removed and the patient placed under observation. Endoscopic follow-up a week later showed mucosal dissection from the middle third of the esophagus toward the back wall exten- Since the 1957 description of intramural esophageal hematoma by Williams, this condition has continued to be a diagnostic challenge ever since. Not only is it infrequent case, but it has been known only from series of cases like case 8 presented above. The esophagus is an organ which is prone to lesions caused by external mechanisms such as foreign bodies, oral tracheal intubation, nasogastric catheters and endoscopic interventions including dilatations and hemostatic therapy. The esophagus is also affected by internal mechanisms including gagging, vomiting and coughing. Risk factors such as esophageal ulcers, esophageal varicose vein sclerosis, hemophilia and coagulopathy have been associated with intramural esophageal hematomas (9-11). In our work, intrinsic mechanisms were seen more frequently than were extrinsic ones while the most frequent comorbidities were high blood pressure and strokes (in contrast to the records in different sets of cases). Medical manifestations such as chest pain, dysphagia and hematemesis were present in a third of the patients (12). In our set, dysphagia and chest pain prevailed in 57% of the patients. There was only one case in which the patient presented the clinical triad reported in the medical literature. Consequently, differential diagnoses were necessary to rule out other possible diagnoses including like aortic 126 Rev Col Gastroenterol / 27 (2) 2012 Case report

5 dissection, acute myocardial infarction, and pulmonary thromboembolism (13). Diagnosis is usually done through upper endoscopy, but when there is the possibility of perforation, thoracic x-rays, esophagography, CT scans and MRIs are used instead (14, 15). All of our cases were diagnosed through endoscopy although when the endoscopy raised a suspicion of perforation esophagography was performed which ruled perforation out. Despite the growing use of radiological studies for diagnosis of esophageal hematoma, we consider upper endoscopy to be more precise and detailed. In addition, it offers immediate therapeutic alternatives in case of complications like endoscopic decompression due to esophageal obstruction. The evolution of esophageal hematoma is usually benign, and most patients recuperate spontaneously with conservative treatment. Consequently, routine endoscopic followups are not recommended (16-18). The patients presented above all progressed in similar fashions except for the one case in which surgery was required to treat a perforation. The outcome of that case was fatal. In the other cases endoscopic follow-ups were performed without obtaining any changes in the course of the disease. This suggests that follow-up endoscopy is not necessary as long as clinical assessment indicates favorable progress. We can conclude that intramural esophageal hematoma is not frequent, occurs predominantly among women, and can be suspected clinically but must be confirmed endoscopically. Treatment should be conservative in most cases, and its most frequent complications are submucosal dissection and perforation. ReferencEs 1. Cullen SN, McIntyre AS.
