  • In pediatric patients, a laryngeal mask airway (LMA) is usually used during minor surgeries that require general anesthesia. No esophageal injury has been reported after insertion of an LMA. We report a case of an esophageal injury with intramural dissection after an i-gel® (size, 1.5; Intersurgical Ltd.) insertion in a pediatric patient. A 2-month-old male infant was hospitalized for left inguinal herniorrhaphy. After induction of anesthesia, a trained resident tried to insert an i-gel® . However, it was only successful after three attempts. Dysphagia was sustained until postoperative day 10, and the pediatrician observed duplication of the esophagus on gastroendoscopy. However, a whitish mucosal lesion, which looked like a scar, was observed, and previous lesions suggestive of esophageal duplication were almost healed on postdischarge day 11. His condition was diagnosed as dysphagia and esophagitis due to an esophageal laceration, not esophageal duplication. He was scheduled for symptomatic treatment with a proton pump inhibitor. In conclusion, although an esophageal injury or perforation in pediatric patients is rare, an LMA insertion or a procedure such as aspiration or nasogastric tube insertion should be performed gently to avoid a possible injury to the esophagus in pediatric patients.
Esophageal injury rarely occurs in children, but it can be fatal, as the mortality rate ranges up to 28% [1] when progressing to perforation. Esophageal injury occurs usually as result of iatrogenic manipulations [2]. There are some causes leading to esophageal injury, such as an endoscopic dilatation, a gastric tube insertion, an endotracheal intubation, and a respiratory suction catheter [1,3].
In pediatric patients, a laryngeal mask airway (LMA) is usually used during minor surgical procedure. It may develop a sore throat due to pharyngeal wall edema as common complication [4]. However, esophageal injury has not been reported. We report the case of an esophageal injury with intramural dissection after an LMA insertion in pediatric patient.
A previously healthy, 2-month-old male infant whose body weight was 6.3 kg was hospitalized for inguinal herniorrhaphy. After induction of anesthesia, a trained resident tried to insert an i-gel® (size, 1.5; Intersurgical Ltd., Wokingham, UK), but the patient could not ventilate via the i-gel®, which was considered as failure of the i-gel® insertion. The resident failed to insert the i-gel® during three times trials and another professional anesthesiologist succeeded to insert the i-gel® at next one trial. Secretions of the mouth and pharynx were suctioned via 6 Fr suction catheter (Vygon, Paris, France) which is soft and has open, straight and rounded tip when the i-gel® was removed, and there was no evidence of pharyngeal injury such as bleeding. The patient got a good recovery from anesthesia without event, but had fever and a large amount of secretions at next day.
A videofl uoroscopic swallowing study was performed due to constant dysphagia and a symptom of aspiration with pneumonia. It showed an aspiration to trachea and suggestive findings of esophageal diverticulum (Figure 1A). Additionally, esophagography was performed and suggested an esophageal duplication located at the left side of upper esophagus with a 5 cm length and no distal communication (Figure 1B and C). Meanwhile, there was no free perforation or contrast leak during this study. Gastroendoscopy confirmed a communicating hole at upper esophagus and infl ammation of surrounded mucosa (Figure 1D).
After confirming, the pediatrician prescribed a proton pump inhibitor, and the patient was discharged in postoperative day 24. During follow-up, gastroendoscopy on postdischarge day 11 showed that a whitish mucosal lesion looked like a scar (Figure 2A) and the previous lesions suggestive of esophageal duplication were almost healed and were the size of a pinhole (Figure 2B). His condition was diagnosed as dysphagia and esophagitis due to an esophageal laceration, not esophageal duplication. He was only scheduled for symptomatic treatment with a proton pump inhibitor.
Esophageal injury associated with a tracheal intubation could occur very rarely [5], but seldom after the insertion of an LMA. In pediatric patients, there are two anatomically weak regions being vulnerable to injury or perforation during procedure; the pharyngoesophageal junction and the Killian’s triangle in the cervical esophagus [6]. We could suspect that the injury began near the pharyngoesophageal junction and accompanied with a longitudinal intramural dissection to upper thoracic level. At fi rst, the esophagographic examination suggested a fi nding to mimic a tubular duplication of upper esophagus.
An esophageal duplication cyst (EDC) may occur in the cervical or abdominal segment, but it commonly occurs in the thoracic segment. A diagnosis is usually made by using endoscopy and an esophagogram, and the presence of an EDC is confi rmed by a histologic examination. Two-thirds of cases with an EDC have ectopic gastric mucosa, which causes ulceration or perforation of the mucosa. In our case, there were two well formed lumens in the upper esophagus, and one of them was closed. The endoscope passed through the other lumen; therefore, an EDC was considered, although an EDC in the cervical segment is rare. However, the fi nding disappeared spontaneously after conservative management, so the possibility of duplication could be excluded.
Although esophageal perforation in pediatric patients rarely occurs, prompt treatment is necessary, because it can progress to fatal events such as mediastinitis, sepsis, and multiorgan failure. To successfully treat esophageal perforation, it is mandatory to diagnose early. Panieri et al. [3] has reported on the treatment of patients who had damage to the esophagus. If the leak is limited to the mediastinum, conservative treatment such as appropriate fl uid therapy, respiratory support, fasting, gastric and pleural drainage, and antibioticis is recommended. However, if there is an intrapleural leakage, surgical treatment such as primary closure should be considered. Currently, there has been a trend toward conservative treatment for esophageal perforation in children [7].
In our case, we could guess two possible causes of esophageal injury. One is the insertion of an i-gel® multiple times forcefully, and the other is the suction of secretion in the oral cavity. The use of an LMA during ambulatory surgery, requiring general anesthesia and airway management, has increased, because it is less invasive compared to tracheal intubation and it provides more reliable ventilation than a face mask. However, when it is inserted too deeply or an LMA is inserted forcefully in surrounding tissue, it may induce a hypopharyngeal injury, which can cause dysphagia and soft tissue emphysema [8]. It is important that an LMA should be inserted gently to avoid a possible injury to esophagus in pediatric patients. Professional person should be called if the insertion of an LMA is failed after multiple trials and another methods which could keep the airway should be considered. As one of the causes of esophageal injury may be related to the suction of the respiratory tract, too high of a pressure should be avoided when an aspiration procedure is necessary, and it is mandatory to stop the procedure if bleeding occurs.
In conclusion, although an esophageal injury or perforation in pediatric patients is rare, when need an LMA insertion or a procedure such as aspiration or nasogastric tube insertion, it should be performed gently to avoid a possible injury to esophagus in pediatric patients.
