INTRODUCTION Self-expandable metallic or plastic stents are more commonly used for the treatment of benign esophageal strictures as a minimally invasive technique. Unfortunately, this technique is not performed without morbidity or mortalities secondary to complications [1, 2]. In this case report, we describe surgical management of a schizophrenic patient who had a partially broken metallic stent which was placed for benign corrosive stricture. CASE REPORT A 39 year-old-male schizophrenic patient had a self-expandable temporary metallic stent placement nine months ago after esophageal stricture secondary to corrosive ingestion in another center. The patient presented to our hospital with dysphagia. The patient was cachectic and malnourished. His complete blood count showed mild anemia and blood biochemistry showed low albumin level. Computerized tomography was done which showed that the stent was migrated to upper stomach (Figure 1). An upper endoscopy revealed that the stent was partially broken and slipped below the strictured segment of the esophagus. An attempt to remove the stent was undertaken but this was not possible because the broken parts of the stent were embedded inside the esophageal wall which posed the risk of perforation. The patient was started with parenteral nutrition and when his nutritional status improved surgical intervention was decided with the consent of the family. Laparotomy and transhiatal esophagectomy with anastomosis on the neck were performed. This served both removals of the migrated stent and strictured, neoplasia prone esophagus. The stricture part of the esophagus was 6 cm (Figure 2). In order to protect the anastomosis, wounds and drains the patient was kept intubated for one week in intensive care unit. On postoperative day 2, the patient had bilateral hemothorax and placement of chest tubes which were removed on postoperative day 5. The patient was extubated at the end seven days, started on Page 4 of 9

The patient was discharged on postoperative day 10 and he was four months out without any complications. DISCUSSION Esophageal stents (ES) are used for both malignant and benign conditions of the esophagus such as unresectable cancer, fistula, corrosive ingestion, iatrogenic perforation and anastomosis leaks [1, 3]. ES can have early (chest pain, aspiration, bleeding perforation, dysphagia) or late (obstruction, tumor ingrowth, tracheoesophageal fistula etc) complications [1, 3]. Fuccio et al reported their rate of migration as 28.6% [4]. ES mostly migrate to stomach or intestines causing perforation or obstruction and some are even passed out rectally. Our patient only had dysphagia. The patient was not aware of the symptoms due to the schizophrenia. In his history we understand that the patient didn t go to the hospital for ES controls because of this his ES wasn t removed in time. Various techniques are available for removal of broken stents. In contrast to the literature, the stent was partially broken in our patient which caused it to get embedded in the esophageal wall which necessitated surgical intervention. Our case is the 10th case in the review of the literature [3]. Corrosive strictures were occurred 35.1% in healthy population after corrosive ingestion [5]. The diagnosis of psychotic disorders in all corrosive material ingestion rate is 3.7% [6]. Corrosive strictures of esophagus pose a 40% risk of malignancy after 20 to 50 years. This fact when added to the unease of endoscopic interventions in a schizophrenic patient made us decide on a radical surgical procedure [7,8]. Keeping the patient intubated until patency of the anastomosis was verified could be considered as radical. But this was necessary as the patient could disrupt the anastomosis by inappropriate ingestion. CONCLUSION Radical resection for benign strictures could prevent complications of repetitive stent placement in schizophrenic patients. Keeping the schizophrenic patient intubated Page 5 of 9

This treatment method was our personal preference. Treatment approached should be multidisciplinary. CONFLICT OF INTEREST There is no any financial interest or any conflict of interest.
