Acute esophageal perforations are potentially life-threatening events that carry high morbidity and mortality rates. There has been a paradigm shift in the standard treatment of acute esophageal perforations from surgery to esophageal stents over the last two decades. We report a case of a 62-year-old male, managed successfully with fully covered esophageal stent for foreign body (denture)-induced acute esophageal perforation. The report also highlights the failure of routine radiological investigation to detect and localize denture (as dentures are made of radiolucent material).

| Introduction|| |
Esophageal perforations are potentially life-threatening, that carries high morbidity and mortality rates. There has been a paradigm shift in the standard treatment of acute esophageal perforations from surgery to esophageal stents over the last two decades. Dentures are made of radiolucent material (poly-methyl methacrylate), which can be missed on routine radiological investigations including CT scan. Esophagogastro duodenoscopy is helpul not only in detection but also in retrieval of dentures. Acute esophageal perforations can be successfully managed with FC-SEMS.
| Case Report|| |
A 62-year-old male referred to our institute, with a history of accidental ingestion of denture 10 days back. There was a history of difficulty and pain during swallowing both for solids and liquids that started after denture ingestion. There was no history of coughing, difficulty in breathing and fever. On examination, crepitus present on palpation of neck and anterior chest. Rest of the systemic examination was unremarkable. Routine blood investigations including hemogram, fasting blood sugar, renal and liver function tests were within normal limits except for neutrophilic leukocytosis (total leucocyte count 18,000 μ/L, with neutrophils of 85%). Water soluble contrast study [Figure 1] of esophagus revealed contrast extravasations from cervical esophagus. Contrast-enhanced–computed tomography (CT) neck and thorax [Figure 2]a and [Figure 2]b revealed left posterior rupture of upper esophagus at D1 level, with extravasations of oral contrast into soft tissue spaces on the lateral aspect of the neck with extensive surgical emphysema in pharyngeal space and cervical soft tissues bilaterally. The surgical emphysema was also extending into the anterior mediastinum, posterior soft tissues on the left side of neck and soft tissues of the left hemithorax. CT of neck did not reveal any metal artefact in our case, as denture is made up of radiolucent polymethylmethacrylate, making imaging diagnosis difficult. Esophagogastroduodenoscopy revealed denture impacted at upper esophagus and retrieved with snare [Figure 3]a.

After denture removal, small rent was noticed on opposite walls of esophagus in upper part of esophagus. In view of acute esophageal perforation, fully covered–self-expandable metallic stent (FC-SEMS) was placed across the esophageal perforation [Figure 3]b and proximal end of SEMS was tied with plastic thread and anchored to canines (to prevent inward migration). He was started per orally after 12 h. FC-SEMS was removed after 6 weeks, and complete healing of esophageal tear was achieved.
| Discussion|| |
Acute esophageal perforations are potentially life-threatening events that carry high morbidity and mortality rates. Due to a lack of a protective serosal surface, perforations of the esophagus can easily expand into the surrounding tissue, leading to mediastinitis and empyema of the pleural cavity. Detection of the radiolucent foreign body like dentures (made of poly-methyl methacrylate a radiolucent material), is difficult with a routine radiological investigation like X-ray and CT making esophagogastroduodenoscopy the investigation of choice for detecting, localizing, and removing radiolucent foreign body as seen in our case. The management of esophageal perforation depends on the site, size, and etiology of the underlying disease.
The reported mortality from treated esophageal perforation is 10%–25%, when therapy is initiated within 24 h of perforation, and it is 40%–60% when the treatment is delayed.
Conventionally, surgery is considered as a gold standard treatment for an acute esophageal perforation. There has been a paradigm shift toward the use of esophageal stents for acute esophageal perforations over the last two decades.
Esophageal stent placement was used primarily for the treatment of malignant strictures until the development of a new generation of biomaterials that allowed the production of easily removable occlusive stents.
Earlier SEMS was reserved for palliation for malignant esophageal strictures and malignant tracheo-esophageal fistulae  because of the potential esophageal damage associated with extraction including reports of irreparable, sometimes life-threatening, fistulae.
Recent advances in biomaterial allowed a new generation of stents to be manufactured that combined a nonpermeable covering, radial force sufficient to occlude a transmural esophageal injury and improved ease of removability. These advances set the stage for utilizing esophageal stents as part of the management algorithm of an acute esophageal perforation. FC-SEMS is safe and less invasive treatment as compared to surgery.
The utilization of FC-SEMS began in high-risk patients who had either previously undergone a failed operative repair or were unsuitable candidates for transthoracic repair of an esophageal leak with success rate of 95%. Some centers have developed hybrid treatment protocol which includes operative or percutaneous drainage of infected spaces, the establishment of enteral nutrition along with esophageal stent placement. Oversize of stent both in length, and diameter (21–25 mm) has beneficial effect on stent migration and seal the leak relatively quickly.
Contrast esophagram is performed, minimum after 24 h after stent placement to document successful leak occlusion.
Factors associated with an increased failure rate of FC-SEMS include esophageal injury >6 cm in length, injury that traversed gastroesophageal junction, proximal cervical esophagus, or leak in gastric conduit in esophagectomy patients.
Regarding optimal time for esophageal stent removal, rates of complications were higher in patients whose stent was left in place for >4 weeks when treating an acute perforation or longer than 2 weeks when treating an anastomotic leak. Leaks which persisted beyond these time intervals were evaluated for surgical repair or a modification of stent therapy.
Success rates of FC-SEMS in the treatment of acute perforations (100%), fistula (71.4%), and anastomotic leaks (80%).
Direct endoluminal closures of iatrogenic perforations have been reported with clips (through-the-scope, over-the-scope) and endoluminal suturing techniques. Endoclips in the esophagus could be considered when perforation diameter is small (<2 cm) but surgical intervention is recommended if perforation is recognized late (greater 24 h), or larger perforation diameter (>2 cm) and if there is evidence of leak into the mediastinum.
| Conclusion|| |
Acute benign esophageal perforations are potentially life-threatening events, and there has been a paradigm shift in management from surgery to esophageal stents (FC–SEMS) over the last two decades. A routine radiological investigation including X-rays and CT has failed to detect radiolucent foreign body such as denture making esophagogastroduodenoscopy the investigation of choice for detecting, localizing, and removing radiolucent foreign body.
