Uncommon foreign body in the hypopharynx: A case report.

RATIONALE: Pharyngeal foreign bodies are a common complaint in emergent cases, and sometimes can be lethal. A large variety of foreign bodies may lodge in the pharynx. We present a case of uncommon foreign body in the hypopharynx. PATIENT CONCERNS: A 9-month-old boy presented for an hour of crying associated with having congee. No abnormality was revealed in physical examination or cervicothoracic computed tomography (CT) scan. Flexible laryngoscopy showed a size tag on the posterior hypopharyngeal wall. DIAGNOSES: Foreign body in the hypopharynx. INTERVENTIONS: The foreign body was removed from the hypopharynx. OUTCOMES: The patient was discharged after the removal of the foreign body. LESSONS: Infants with foreign bodies in the hypopharynx may presented with no obvious clinical manifestation. Pharyngeal foreign bodies may be the potential for disastrous consequences. Otolaryngologists should pay attention to these foreign bodies.

Abrasion and blunt tissue trauma study of a novel flexible robotic system in the porcine model.

OBJECTIVES: The objective of this study was to determine if a flexible robotic system caused increased tissue reaction when accessing the oropharynx and hypopharynx compared to intubation controls in only 2 scenarios: high speed tissue impact and multiple unit insertions and retractions. The data obtained were submitted as part of the entirety of information submitted for FDA approval. METHODS: This study consisted of 5 groups of Yorkshire pigs (2 animals per group). On Day 0, all animals were intubated. For group 1 (control), a second endotracheal tube was advanced to just above the vocal cords. In abrasion groups 2 and 3, the flexible robotic system was advanced against the oropharyngeal and hypopharyngeal tissues, respectively. In blunt trauma groups 4 and 5, the flexible robotic system was advanced at maximum speed (22mm/s) to collide with oropharyngeal and hypopharyngeal tissues, respectively. Pre- and post-procedure endoscopic assessments of tissue reaction were performed daily for 4 days. An independent reviewer graded tissue reaction using a 0-3 point scale. RESULTS: Tissue reaction scores at each observation time point for all test groups were less than or equal to control scores except for one instance of moderate scoring (2 out of 3) on Day 2 for an animal in the blunt trauma group where reaction was likely intubation-related rather than device impact related. Otherwise, all flexible robotic system-treated animal scores were less than 1 by Day 4. CONCLUSIONS: In this limited study, the flexrobotic system afforded surgical access to the oropharynx and hypopharynx without an increased level of abrasion or tissue trauma when compared to intubation alone.

Total esophageal substitution for combined hypopharyngeal and esophageal strictures after corrosive injury in children.

BACKGROUND/PURPOSE: The treatment of children with esophageal strictures and involvement of the hypopharynx caused by caustic substance ingestion continues to be challenging. The aims of the present study are to describe the peculiarities of the technique of complete esophageal substitution for the treatment of children with severe caustic strictures (pharyngocoloplasties) and to compare the results to those of classical esophagocoloplasty with thoracic and abdominal esophageal substitution in another group of children. METHODS: A total of 258 children underwent colon interposition for esophageal replacement. Among these patients, 19 had complex esophageal caustic strictures involving the high level of the esophagus and hypopharynx without response to endoscopic dilatations. This group was compared with another group who required partial esophagocoloplasty with intact hypopharynx and high esophagus (239 patients). For the pharyngocoloplasty procedure, the transverse and great parts of the right colon were the segments selected for interposition and were maintained by a double vascular pedicle based on the left colic vessels and the marginal paracolic arcade via the sigmoid vessels. RESULTS: In the pharyngocoloplasty group, 9 patients (47.4%) presented with cervical anastomosis stenosis with episodes of aspiration pneumonia, although good responses to endoscopic dilatation treatments were observed. All patients survived. In the esophagocoloplasty group, the main complications were cervical leaking (18.0%) and stenosis (16.7%). Statistical comparisons revealed that the pharyngocoloplasty patients exhibited a lower incidence of cervical leakage and increased incidences of cervical stenosis and aspiration pneumonia, although all patients could swallow normally. CONCLUSION: Pharyngocoloplasty with complete esophageal substitution is a safe and effective procedure for the treatment of esophageal caustic strictures with severe stenoses reaching the hypopharynx that are refractory to previous endoscopic treatment. LEVEL OF EVIDENCE: II.

The Sternocleidomastoid Muscle Flap: A Versatile Local Method for Repair of External Penetrating Injuries of Hypopharyngeal-Cervical Esophageal Funnel.

INTRODUCTION: A primary repair of external penetrating injury to hypopharyngeal-cervical esophageal (HP-CE) funnel without reinforcement has more complications if compared with muscle reinforcement. The aim of the present study was to assess the outcome of using sternocleidomastoid (SCM) muscle flap for reinforcement of primary repair of HP-CE funnel injury. The study proposed an algorithm for different uses of SCM flap repair according to site and size of funnel perforation. PATIENTS AND METHODS: A prospective analysis of 12 patients, who had surgical treatment for external penetrating injuries of HP-CE funnel between January 2011 and September 2014, was recorded. The following factors were studied for each case: demographic data, Revised Trauma Score (RTS), mechanism of injury, time interval between injury and definitive surgical care, injury morphology, any associated injuries, technique of SCM flap used, length of hospital stay, and surgical outcome and complications. RESULTS: They were 10 males and 2 females and the mean age was 31.9 years. The cause of injury was stab wound in 5 (41.7 %) cases, gunshot injury in 4 (33.3 %) cases and 3 (25 %) cases after anterior cervical spine surgery. Isolated injury to HP and CE was recorded in 5 cases (41.7 %) for each site. However, 2 (16.7 %) cases had injury to both HP and CE. Cranially based SCM flap was mainly used in cases with HP injury and caudally based flap in CE cases with some limitations. The whole muscle flap was used in large (≥ 1 cm) defects while and the split muscle flap in small (<1 cm) defects. Oral intake started 7 days postoperatively with only one (8.3 %) case of small leakage, which was treated conservatively. CONCLUSION: The SCM flap is a very useful and versatile tool in reinforcement of HP-CE funnel injury with the advantages of high success rates of leakage prevention.

Hypopharyngeal perforation caused by intraoperative transesophageal echocardiography.

Intraoperative transesophageal echocardiography (TEE) is an invaluable tool for cardiac surgical decision-making. TEE is considered reasonably noninvasive and safe, but insertion and manipulation of the TEE probe can lead to complications. Here, we report a patient with aortic stenosis who experienced TEE-associated hypopharyngeal perforation at the pyriform sinus complicated by esophageal trauma, pneumomediastinum and pneumoretroperitoneum. Based on this case, we suggest that rare complications be kept in mind when using TEE intraoperatively.

Management of cervical esophageal and hypopharyngeal perforations.

PURPOSE: Evidence is limited for outcomes of surgical versus conservative management for patients with cervical esophageal or hypopharyngeal perforations. METHODS: Patients with cervical esophageal or hypopharyngeal perforations treated between 1994 and 2014 were identified using an institutional database. Outcomes were compared between patients who underwent operative drainage and those who had conservative management with broad-spectrum antibiotics and withholding oral intake. RESULTS: Twenty-eight patients were identified with hypopharyngeal or cervical esophageal perforations, mostly due to iatrogenic (nasogastric tube placement, endoscopy, endotracheal intubation) injuries (68%). Fourteen were treated initially with conservative management and 14 with initial surgery. Six patients failed conservative treatment and two patients failed surgical treatment. Patients managed conservatively who had eaten between injury and diagnosis (p=0.003), those who had 24 hours or more between the time of injury and diagnosis (p=0.026), and those who showed signs of systemic toxicity (p=0.001) were significantly more likely to fail conservative treatment and require surgery. No variables were significant for treatment failure in the surgical group. Of the 20 patients who ultimately underwent a surgical procedure, two required a second procedure. CONCLUSION: Patients who have eaten between the time of perforation and diagnosis, have 24 hours or more between injury and diagnosis, and those that show signs of systemic toxicity are at higher risk of failing conservative management and surgical drainage should be considered. For patients without these risk factors, a trial of conservative management can be attempted.

Bilateral hypopharyngeal perforations caused by penetrating trauma to the neck.

External laryngeal trauma is a relatively rare-encountered and sometimes life-threatening emergency condition. Recognition of laryngeal injury related to either blunt or penetrating trauma is important for both initial preservation of life as well as long-term airway and vocal function. Treatment options include medical management with observation and open surgical treatment with or without tracheotomy. We, herein, describe a 23-year-old male case who sustained external penetrating trauma to lateral aspect of neck. The etiology, clinical manifestations, investigation modalities and management of penetrating neck trauma were discussed in the light of the literature data.

Accidental cell phone ingestion with pharyngeal impaction.

BACKGROUND: 35 year old intoxicated male ingested an unusual, large foreign object (cell phone). OBJECTIVE: To report the ingestion of an unusual large foreign object with hypopharyngeal impaction, complications, and treatment. DISCUSSION: Foreign body ingestion in the adult population is more prevalent in those who engage in drug or alcohol abuse. Impaction and perforation of the upper aerodigestive tract can lead to significant and potentially fatal complications including parapharyngeal/retropharyngeal abscess, mediastinitis, and aortoesophageal fistula. The treatment of foreign object ingestion is dependent on the type of foreign object ingested, its location, and potential for perforation. Endoscopic removal under general anesthesia is the treatment method recommended for foreign bodies impacted at the cricopharyngeus or esophagus. CONCLUSIONS: We report the only case of the accidental ingestion of an entire cell phone with casing. A plain film x-ray of the neck can be used in the assessment of the location of radiopaque foreign objects and in diagnosing potential complication.

Vocal cord paralysis caused by stingray.

Foreign bodies in the oral cavity and pharynx are commonly encountered in the emergency room and outpatient departments, and the most frequently observed of these foreign bodies are fish bones. Among the possible complications resulting from a pharyngeal foreign body, vocal cord fixation is extremely rare, with only three cases previously reported in the English literature. The mechanisms of vocal cord fixation can be classified into mechanical articular fixation, direct injury of the recurrent laryngeal nerve, or recurrent laryngeal nerve paralysis secondary to inflammation. The case discussed here is different from previous cases. We report a rare case of vocal cord paralysis caused by the venom of a stingray tail in the hypopharynx.

Total laparoscopic esophageal bypass using a colonic conduit for corrosive-induced esophageal stricture.

BACKGROUND: The colon and the stomach are the most commonly used conduits for esophageal replacement in patients with esophageal strictures resulting from corrosive ingestion. The replacement surgeries have traditionally been performed by an open approach. While laparoscopic replacement surgery using a stomach conduit has been previously reported, a total laparoscopic bypass using a colonic conduit has not been previously described. We herein describe the surgical technique and results of laparoscopic esophageal bypass using a colonic conduit. METHODS: Patients with corrosive stricture involving the esophagus with the proximal level at the hypopharynx, or those with concomitant gastric scarring, were selected. The surgery was performed with the patient in a supine position using five abdominal ports and a hockey stick/transverse skin crease neck incision. The main steps include colonic mobilization and assessment of the adequacy of the marginal vascular arcade, creation of a retrosternal tunnel, preparation of the colonic conduit, neck dissection, delivery of the colonic conduit into the neck and cervical pharyngo/esophagocolic anastomosis, and intra-abdominal cologastric and ileocolic anastomosis. RESULTS: During the study period, 39 patients with corrosive stricture of the esophagus were managed surgically at our center with either gastric or colonic bypass. Of these, 22 patients underwent an open procedure (12 retrosternal colonic bypasses and 10 retrosternal gastric bypasses) and 17 patients underwent a laparoscopic procedure (13 retrosternal gastric bypasses and 4 retrosternal colonic bypasses). Patients with stricture at the hypopharynx (n = 2) or those in whom the stomach was contracted (n = 2) were considered for a laparoscopic esophagocoloplasty. The average duration of surgery of these latter four patients was 370 (380, 320, 360, and 420) min and the mean estimated blood loss was 100 mL. All patients could be ambulated on the first postoperative day and were allowed oral liquids by the 7th postoperative day. Compared with patients who underwent an open colonic bypass, there was significantly less need for analgesics. At a median follow-up of 5 (range 3-6) months, all patients are euphagic to solid diet and have excellent cosmetic results. CONCLUSION: Laparoscopic colonic bypass is an achievable, safe, and effective procedure for the management of corrosive strictures of the esophagus.

Larynx, hypopharynx and mandible injury due to external penetrating neck injury.

Esophageal and laryngeal injuries due to ballistic injuries are seldom encountered. Ballistic external neck traumas generally result in death. Incidence of external penetrant neck injuries may vary between 1/5000-137000 patients among emergency service referrals. Vascular injuries, esophagus-hypopharynx perforations, laryngotracheal injuries, bony fractures, and segmentations may be encountered in external neck traumas. Here we report a 27-year-old male patient who was referred to our emergency department and presented with hyoid bone fracture, multiple mandibular fractures, and hypopharynx perforation due to a ballistic external neck injury.

Cervical oesophageal and hypopharyngeal perforations after anterior cervical spine surgery salvaged with regional and free flaps.

BACKGROUND AND PURPOSE: The object of the study was to present our own experience in the management of cervical oesophageal and hypopharyngeal perforations after anterior cervical spine surgery. MATERIAL AND METHODS: The study group consists of 5 patients treated in Department of Otolaryngology Poznan University of Medical Sciences in 2009-2011. Different materials and techniques were used to repair the perforations: infrahyoid flap, primary sutures supported by sternocleidomastoid muscle flap, thigh flap and forearm flap in two cases. RESULTS: Four out of 5 patients were referred to our department in a poor general condition, with infected neck fistulas, three patients after prolonged conservative treatment, and three patients after initial attempts to repair the perforation outside our institution. One-stage reconstructive surgery was successful in three cases, while in two others secondary interventions were necessary. Total hospital stay ranged in the analysed group from 23 to 191 days, hospital stay in our department from 1 to 62 days, hospital stay from the final procedure from 18 to 26 days. Swallowing function was within normal limits in all cases 12-14 days after the surgery. CONCLUSIONS: The authors' experience shows that in long-lasting and infected cervical oesophageal and hypopharyngeal perforations following anterior cervical spine surgery distant flaps should be primarily used as a source of a well-vascularized and unchanged tissue. It seems to be crucial to repair the perforations immediately after the first symptoms appear - such an approach significantly reduces total hospital stay and improves the prognosis.

[Esophagoplasty in combined scarry lesions of the esophagus, laryngopharynx and the trachea in children].

The experience of plasty of the pharynx and esophagus with graft of the free small intestine segment was presented in 12 children after burn stricture by the potassium permanganate. The technical aspects of operation using methods of the reconstructive vascular surgery were described. Good short-term result was obtained in all the patients. The long-term results were investigated during 15 years. It was observed, that the graft diverticulum developed by 4-7 years in 3 patients, whom repeated operation should be performed. According to the authors, the regional plasty of the esophagus by free revasculizated small intestine graft was really effective surgical supply and could be considered as the method of choice in limited scarry lesions of the pharynx and cervical esophagus, but the method should be improved.

A bone to pick? Fish bones of the upper aerodigestive tract: review of the literature.

BACKGROUND: Fish bones are of particular interest to the otolaryngologist as accidental ingestion is one of the most common reasons for otolaryngology-related emergency department referrals. Furthermore, removal of fish bones deeply lodged in the oropharynx or hypopharynx can be both hazardous and technically difficult, and failure to accomplish safe removal could result in considerable morbidity and various critical complications. OBJECTIVE: We present here a literature review on the topic of fish bones in otolaryngology with a focus on selection of patients for intervention and on removal techniques. We emphasize that retained fish bones should be approached with caution as their course can at times be unpredictable, as we describe here.
