Intramural esophageal dissection due to pharyngeal abscess treated by endoscopic esophageal transection: a case report

A case of submucosal abscess of the esophagus mimicking a mediastinal abscess

We report a case of a submucosal abscess of the esophagus that required differentiation from a mediastinal abscess. A 48-year-old man presented with a chief complaint of fever and sore throat. He did not remember swallowing a foreign body, and his oral cavity showed no signs of inflammation. Contrast-enhanced computed tomography showed a low density area with enhancement in the mediastinum, especially around the esophageal wall. We planned to perform surgical drainage with the intention of performing intraoperative endoscopy from the beginning. We performed surgical drainage through a left cervical oblique incision; however, there was no exudate obtained from the mediastinal space. Despite the reported absence of accidental ingestion of a foreign substance, intraoperative endoscopy was performed that revealed a laceration in the esophageal mucosa 24 cm from the incisors. We diagnosed it as a submucosal abscess of the esophagus and prescribed parenteral antibiotics. Submucosal abscess of the esophagus can occur even in the absence of awareness of a foreign body ingestion or oral infection. In case that the abscess was not localized clearly within the outer membrane of the esophagus, the coincidental mediastinal drainage via a cervical incision and intraoperative endoscopy seemed to be useful.

Intramural Esophageal Abscess Complicated with Pleural Fistula: A Case Report

Intramural esophageal abscess is a rare entity caused by mucosal injury to the esophagus but without transmural perforation. The mucosal disruption provides access to the intraluminal infectious contents to traverse into the loose submucosal tissue, resulting in an intramural abscess. It is important to be well-versed in the clinical and imaging findings of this pathology in order to make a timely diagnosis. Here, we present a case of intramural esophageal abscess complicated with a pleural fistula with a focus on the radiological features of this rare entity. To our knowledge, this is the first time that an esophageal intramural abscess complicated with pleural fistula is discussed in peer-reviewed literature.

Intramural oesophageal abscess: an unusual complication of tonsillitis

Tonsillitis is an extremely common condition, usually it is self-limiting, of viral origin, and managed conservatively in general practice. Rarely patients require inpatient management, usually when bacterial infection is present or when the cause is virulent organisms such as Epstein Barr virus. Complications can be divided into non-suppurative; sepsis, scarlet fever, rheumatic fever, glomerulonephritis and Lemierres disease, and suppurative; quinsy, parapharyngeal abscess and retropharyngeal abscess, respectively. Anecdotally, there is concern that modern medical practice that counsels vigilance against overuse of antibiotics, could lead to increased complications of tonsillitis. We report a case of an otherwise healthy man who presented with dysphagia, odynophagia and neck pain following a sore throat. Despite antibiotic treatment he developed an intramural oesophageal abscess, to our knowledge, an unreported complication of tonsillitis.

First successful treatment of a circumferential intramural esophageal dissection with perforation in a patient with eosinophilic esophagitis using a partially covered self-expandable metal stent

Intramural esophageal dissection (IED) is a rare disease characterized by a partial (PIED) or circumferential (CIED) mucosal rupture. Whereas PIED responds well to nonoperative treatment, complicated courses have been reported necessitating surgery, up to the point of esophagectomy despite complex endoscopic interventions, in CIED. We report the first case of an iatrogenic CIED with perforation in a young patient with underlying eosinophilic esophagitis treated successfully by endoscopy alone, using a partially covered self-expandable metal stent.
