iverticula in the human body usually produce symptoms caused by pressure on the surrounding organs or by the deterioration of their mucosal lining. However, intramural esophageal diverticula are associated with symptoms of gastroesophageal reflux or related symptoms and signs not quite related to their pathogenesis or pathophysiology. We review the cases of three patients, which may somewhat illuminate the nature of these unusual and rare diverticula.

An esophagram revealed multiple intramural pseudodiverticula, a moderate lower esophageal stricture, and a hiatal hernia (Fig 1). Endoscopy showed food impaction, a mild stricture, and a hiatal hernia (Fig 2). Biopsy revealed pseudodiverticula of the esophagus, hypertrophy of Accepted for publication March 10, 2015.

More than 50 years ago, two investigators described a rare case of multiple esophageal diverticula, which they named esophageal intramural pseudodiverticulosis (EIPD). To this day, the pathogenesis of this condition remains obscure. Several coexisting conditions, such as strictures, esophageal dysmotility, or infection, require medical treatment. We present two typical cases of EIPD and one case of a rare single esophageal intramural diverticulum. (Ann Thorac Surg 2016;101:769–71) Ó 2016 by The Society of Thoracic Surgeons

Comment In 1975, only 11 cases of esophageal intramural pseudodiverticulosis (EPID) had been reported. As of 2006, only 220 had been reported [1]. EIPD can occur at any age, although it is much more common in older adults; the average age is 53.3 years, and the higher incidence occurs in men [1]. As of 2000, 13 cases had been reported in children [2, 3]. Esophageal pseudodiverticula were first reported in 1960 [4]. The pathophysiology of EIPD is poorly understood. It was hypothesized that EIPD was the result of asynchronous contraction producing increased pressure and formation of diverticula in weakened points of the esophageal wall. No single dysmotility pattern was detected [4]. Inflammatory obstruction of deep mucosal glands was thought to play a role in the etiology [5]. With continued analysis, it is thought today that a chemical, mechanical, or infectious process causes obstruction of the outlet of excretory ducts. The obstruction causes reactive hypertrophy with increased intraluminal pressure resulting in a pseudodiverticulum [1, 3]. EPID is regularly associated with severe esophagitis [1], as in our first patient. A higher incidence of esophageal intramural diverticulosis is seen in patients with diabetes mellitus, hiatal hernias, and chronic alcoholism [1, 6]. Patient 1 had two of these three conditions. Although dysphagia is the most common presentation, odynophagia is more common in patients with hiatal hernia. Hemorrhage is associated with EIPD, as seen in patient 2, whose case was first published in 2001 [6]. A strong association with esophageal webs was first seen by Hahne and colleagues [6].

Aorto-left atrial fistula (AAF) is rarely encountered in clinical practice, and the early diagnosis can be very challenging. This report describes a unique case of AAF caused by a gunshot injury and the pivotal role of transesophageal echocardiography for diagnosis and assessment.

istulae between the aorta and the left atrium are rarely observed, and previous case reports have been associated with complications of cardiovascular disease, surgery, or intervention [1, 2]. Here we present a unique case of a gunshot-induced aorto-left atrial fistula (AAF) diagnosed by intraoperative transesophageal echocardiography. A 19-year-old male suffered a gunshot wound to the thorax, and he was resuscitated at the scene by emergency personnel prior to being transported to the emergency department (ED) at our institution. Initial physical examination in the ED revealed a very narrow pulse

Inflammation of the submucosal glands and excretory duct dilatation have been identified [1]. Inflammatory cells and submucosal fibrosis are also seen [1]. It is unknown what leads to duct outlet obstruction, and this gap in knowledge raises the question of compound causes and secondary or primary esophageal infections. A barium swallow will show structure, hypertonicity, hypotonicity, or a combination in almost every case [5]. Some literature reports cite more than 90% of patients with EIPD having strictures on endoscopy. A barium esophagram shows flasks or button-shaped outpouchings consistent with dilatation of the submucosal glands [1]. The literature suggests that as little as 20% to 25% of EIPD are found on endoscopy [1, 5, 3]. Esophageal testing may reveal esophageal dysmotility. This is a classic example of the inflammatory cause versus dysmotility cause that has been debated for more than 50 years. The main goal of treatment is correction of the underlying pathologic disorder. Strictures respond to dilation, proton pump inhibitors, and antifungal medication [6]. Fundoplication stops the acid reflux and the mucosal injury, which, if allowed to continue, result in enlargement of the diverticula after only months and may lead to eventually carcinoma. Single diverticula are rare. As of 2000, 13 cases had been reported in children [3]. The youngest patient reported was 37 days old, the mean age being 11 years. The presenting symptom is dysphagia. Diagnosis is made by esophagram [1, 7]. Although it is a benign condition, fistulas to the mediastinum may be fatal [7]. It is still unknown whether pediatric esophageal intramural diverticulum is acquired or congenital [7, 8]. The congenital origin is supported by the association of other congenital anomalies such as tracheoesophageal fistula and esophageal webs [8]. The acquired origin is supported by development from a normal esophagus to one with esophageal intramural diverticulum in as short a time as 7 months [7]. Association with gastroesophageal reflux, strictures, corrosive acid ingestion, and dysmotility have been reported [8]. Asthma, producing increased negative-positive intrathoracic pressures, may play a role [7]. Reflux has been known to provoke asthmatic attacks [2]. The child (patient 3) had a single intramural diverticulum without other identifiable cause. Excision cured the child.
