Case Report

An 87-year-old man suffering from hiatal hernia and a Schatsky ring was coming to our unit for 15 years for regular dilations with Maloney dilators. In the last procedure, several minutes after dilation, the patient complained of chest pain. An upper endoscopy was performed. A huge tear in the left lateral side of the lower esophagus was seen (Fig. 1). Immediately, in that moment, insertion of a coated self-expanding stent was deemed to be the most appropriate measure. The gastroscope was advanced until the second duodenal portion and a superstiff guidewire was passed through the working channel of the endoscope. The gastroscope was withdrawn and a 10 cm long esophageal Ultraflex®, partially covered, was inserted with only endoscopic monitoring (1). The patient was admitted with n.p.o. and fluidotherapy. Four hours later, a CT thoracic scan was performed. No free air was seen in the mediatinum and the stent was in correct position.

 

Only mild chest discomfort was noted. The patient began to eat a clear diet 48 hours after the procedure. The stent was removed 17 days later, grasping and pulling the string located in its upper end (Fig. 2). Unfortunately, the string was broken. Afterwards, the extraction manoeuvre succeeded grasping a similar string located in the distal end of the stent (Fig. 3). The patient did well.

 

Discussion

Removable esophageal stents have proven to be useful for healing esophageal perforations and leaks (2). The sooner the esophageal tear is sealed, the greatest the likelihood of an uneventful recovery for the patient. Besides, modern esophageal stents are easy to insert and many of them can be removed safely in a few weeks. After a dilation procedure, if there are serious concerns about a perforation has occurred, perhaps it is appropriate the immediately insertion of a covered removable esophageal stent to seal the possible perforation.

Maloney dilators have no an inner orifice to be slide over a guidewire like, for instance, Savary dilators. However, Maloney-type dilators are still used nowadays not only for physician controlled dilation but also for patient self-dilations in chronic benign esophageal strictures (3).
