Manometry demonstrates diffuse esophageal spasm with simultaneous contractions of the esophagus observed throughout the tracing. There appears to be a functional imbalance between excitatory and inhibitory postganglionic pathways, disrupting the coordinated components of peristalsis. Zenkers diverticulum (posterior hypopharyngeal diverticulum) is an acquired mucosal herniation through an area of anatomic weakness in the region of the cricopharyngeal muscle (Killians dehiscence). About 50% of these patients are asymptomatic and present with a neck mass caused by cervical nodal metastases. If infected, the wall of the branchial cleft cyst becomes thickened and may enhance with the administration of intravenous contrast medium. This work supports a comprehensive evaluation of both the pharynx and the esophagus for patients with complaints of bolus stasis . [QxMD MEDLINE Link]. These disorders may manifest as oral stasis of food, inability to initiate a swallow, premature spillage. The lower esophageal sphincter (LES) pressure tracing is at the level of the sleeve (tracing 6). Some pharyngeal and cervical esophageal webs are associated with diseases that cause inflammation and scarring, such as epidermolysis bullosa or benign mucous membrane pemphigoid. Pandolfino JE, Fox MR, Bredenoord AJ, Kahrilas PJ. 2011 Nov. 21(4):465-75. UES opened for a portion of the bolus to pass through, pharyngeal stripping was not great. bringing food back up, sometimes through the nose. Pharyngeal phase problems include -having a hard time starting a swallow -getting food or liquid into your airway, called aspiration -having some food or liquid stay in your throat after you've swallowed, called residue. This website also contains material copyrighted by 3rd parties. PMC An esophagram demonstrating the corkscrew esophagus picture observed in a patient with manometry confirmed findings of diffuse esophageal spasm (DES). Neurological disorders affecting oral, pharyngeal . A videofluoroscopic swallow study (VFSS) allows for visualization of the oral, pharyngeal, and esophageal phases of the swallow. Share cases and questions with Physicians on Medscape consult. The relationship of contraction and food bolus is more complex because of intrabolus pressures from above (contraction from above) and the resistance from below (outflow resistance). Questionable dysmorphic features, we are awaiting genetic testing results. The proximal esophagus is predominantly striated muscle, while the distal esophagus and the remainder of the GI tract contain smooth muscle. 223 0 obj <> endobj American Neurogastroenterology and Motility Society, American Society for Gastrointestinal Endoscopy, American College of Physicians-American Society of Internal Medicine. At rest, the barium-filled diverticulum extends below the level of the cricopharyngeal muscle posterior to the proximal cervical esophagus ( Fig. Scleroderma esophagus is associated with severe and progressive acid reflux symptoms and complications. %PDF-1.6 % Sonnenberg A. Barium studies allow detection of more than 95% of structural lesions below the pharyngoesophageal fold. [QxMD MEDLINE Link]. Likely at risk for bolus mis-direction from below (refluxate), d/t what sounds like proximal hypotonia that could make timely effective response to retrograde flow from the esophageal body unreliable. Image courtesy of Andrew Taylor, MD, Professor, Abdominal Imaging, Department of Radiology, University of Wisconsin Medical School, Madison. A dynamic examination reveals a higher percentage of webs than spot images alone. However, the impact of posterior tongue ties on the pharyngeal phase of swallowing is not well documented in the literature. Cochrane Database Syst Rev. Patients with external or mixed laryngoceles may have a compressible lateral neck mass. The secondary peristaltic wave is induced by esophageal distension from the retained bolus, refluxed material, or swallowed air. Barium studies are contraindicated because they may exacerbate edema, triggering an episode of acute respiratory arrest. Epub 2021 Feb 5. However, barium studies may reveal enlargement of the aryepiglottic fold with a smooth overlying mucosa. 2015 Oct. 8(5):255-63. Nonperistaltic isolated contractions or low-amplitude simultaneous contractions of the esophageal body may be observed. On frontal radiographs obtained in patients with lymphoid hyperplasia, multiple smooth, round, or ovoid nodules are symmetrically distributed over the surface of the base of the tongue ( Fig. Radiographic findings in pharyngeal carcinoma. Other diseases of pharynx. Int J Mol Sci. Image courtesy of Andrew Taylor, MD, Professor, Abdominal Imaging, Department of Radiology, University of Wisconsin Medical School, Madison. All the etiologies that I mentioned, in isolation or in combination, could play a part in the diffuse pharyngeal stasis/residue observed, which is worrisome for bolus mis-direction during the course of a true feeding. When advanced, this condition can lead to such severe dysphagia that malnutrition, weight loss, and dehydration can develop. Achalasia is associated with significant and progressive symptomatic discomfort. Branchial ridges (arches) lie between the branchial clefts. 2014. The dysmorphic features stand out as worrisome, and often craniofacial and cardiac variants like an ASD can co-occur. Computed tomography (CT) and MRI may occasionally reveal lesions (typically submucosal masses) that are not visible, even with modern endoscopes. Barium that is retained in pouches during swallowing spills into the ipsilateral piriform sinus after the bolus passes. Primary peristalsis is the peristaltic wave triggered by the swallowing center. On lateral views, the anterior wall of the sac is anterior to the cervical esophagus, below the level of the cricopharyngeal muscle. 2015 Jul. 2013 Jun. Schlottmann F, Patti MG. Primary esophageal motility disorders: beyond achalasia. In one autopsy series, 16% of patients had incidental cervical esophageal webs. Familial clustering is observed, but a genetic relationship is not established. Some patients with Zenkers diverticulum are asymptomatic. Patients with impaired base of tongue movement and impaired pressure generation resulting in pharyngeal residue in the setting of a normal neurologic workup could possibly present with a posterior tongue tie which should be examined and included in the differential diagnosis. The pathogenesis is not well documented, but chronic mucosal irritation is incriminated. The longitudinal muscle is responsible for shortening the esophagus, while the circular muscle forms lumen-occluding ring contractions. Although esophagram shows a typical picture of achalasia, this patient had adenocarcinoma of the gastroesophageal junction. sharing sensitive information, make sure youre on a federal 2010 Feb. 22(2):142-9, e46-7. Radiographically, a small (3-20mm in diameter), round to ovoid, smooth-surfaced outpouching is seen just below the level of the cricopharyngeal muscle ( Fig. 16-10 ). E93q">G8}wEkeW8 Accessibility Rarely, pedunculated lesions (e.g., papillomas, lipomas, fibrovascular polyps) may be coughed up into the mouth or may cause sudden death through asphyxiation. There are no criteria based on size for differentiating nodularity of the base of the tongue because of normal lingual tonsils from that resulting from reactive lymphoid hyperplasia. 16-2 ). High-resolution manometry in clinical practice: utilizing pressure topography to classify oesophageal motility abnormalities. The LES relaxes during swallows. Medical team is very supportive of therapy. Complications of botulinum toxin injections for treatment of esophageal motility disorders. Ulcerative lesions may deeply penetrate the tongue and valleculae and invade the pre-epiglottic space ( Fig. [QxMD MEDLINE Link]. Aryepiglottic fold nodules or mass lesions may cause dysphonia or respiratory symptoms such as stridor. The junction of the ala of the thyroid cartilage and thyrohyoid membrane is seen on frontal views as a notch in the lateral pharyngeal wall. Praveen K Roy, MD, MSc Clinical Assistant Professor of Medicine, University of New Mexico School of Medicine a sensation that food is stuck in your throat or chest. However, no studies to date have shown convincing evidence that surveillance is worthwhile. This delayed spill may result in dysphagia or a choking sensation because of overflow aspiration. Life expectancy is not affected, and weight loss is rare. Cricopharyngeal dysfunction is most common in older adults. 2016 Apr 30. No nasopharyngeal regurgitation that I recall. Reasons for the swallow study were bedside symptoms of desaturations during oral feeding at ~37 weeks PMA and a steady decline in his oral intake & feeding cues. Abdullah Fayyad, MD, MBBS is a member of the following medical societies: American Gastroenterological AssociationDisclosure: Nothing to disclose. Hospitalization for achalasia in the United States 1997-2006. Image courtesy of Andrew Taylor, MD, Professor, Abdominal Imaging, Department of Radiology, University of Wisconsin Medical School, Madison. The pathogenesis of Zenkers diverticulum is as controversial as the muscular anatomy. 2015 Dec. 174(12):1629-37. (From Rubesin SE: Pharynx. Branchial pouch sinuses arise from the tonsillar fossa (second pouch), upper anterolateral piriform fossa (third pouch), or lower anterolateral piriform sinus (fourth pouch; Fig. The 5-year survival rate is 20% to 40%. Retention cysts and granular cell tumors are the most common benign tumors of the base of the tongue ( Fig. Racial and environmental differences in the incidence of achalasia and other esophageal motility disorders might be present; however, because of the low incidence of disease and underdiagnosis in developing countries, these differences have not been demonstrated. 245 0 obj <>stream ASHA / Pharyngeal Phase Bolus. With severe luminal narrowing, dysphagia may result, especially in patients with circumferential cervical esophageal webs. He also gets very constipated. Overall low energy and alertness for his age. PVA was injected under fluoroscopic monitoring until significant stasis of the artery was noted. Several older northern European series showed an association of cervical esophageal webs, iron deficiency anemia, and pharyngeal or esophageal carcinoma. No reliable information for other motility disorders exists. Webs also should not be confused with a prominent cricopharyngeal muscle, which appears as a round, broad-based protrusion from the posterior pharyngeal wall at the level of the pharyngoesophageal segment. Lateral radiographs may show the air-filled sac anterior to the epiglottic plate, in contrast to a lateral pharyngeal diverticulum, which lies posterior to the epiglottic plate.
