Aging and the esophagus: Common pathologic conditions and their effect upon swallowing in the geriatric population

Dysphagia in the elderly is most often oropharyngeal or hypopharyngeal in location and neuropathologic in etiology. Aging itself, although causing demonstrable structural and functional changes in the esophagus, does not cause any clinically relevant esophageal dysphagia. A variety of pathologic conditions seen in the geriatric population affect the esophagus and can alter esophageal function, resulting in symptomatic dysphagia. Accurate diagnosis requires a thorough evaluation performed in an unhurried fashion, often with the assistance of ancillary personnel. Treatment of these esophageal disorders is multidisciplinary and may involve dietary manipulations, the administration of medications, therapeutic endoscopic procedures, and occasionally surgery.     

Comparison of Esophageal Motility in Patients with Solid Dysphagia and Mixed Dysphagia

It is unclear whether there is any difference in esophageal motor abnormalities between patients complaining of dysphagia for solids or both solids and liquids. The aim of this study was to determine any difference in the manometric findings between patients with dysphagia for solids and those with mixed dysphagia. Manometric tracings were performed in 200 consecutive patients (66M, 134F; mean age = 51 years) with nonobstructive dysphagia. Ambulatory pH studies were performed in all patients. Subjects were divided into two groups: patients with solid dysphagia (n = 94, 33M, 61 F; mean age = 51 years) and those with mixed dysphagia (n = 106, 33M, 73F; mean age = 51 years). A normal motility study was the most frequent finding. Achalasia occurred more frequently in patients with mixed dysphagia than in those with solid dysphagia (12% vs. 3%, p < 0.01). Gastroesophageal reflux disease (GERD) was observed in 59% of patients with solid dysphagia compared with 29% of patients with mixed dysphagia (p < 0.02). The most common esophageal motility abnormality is nonspecific esophageal motility disorders. This study has shown that abnormal esophageal motility occurs slightly more in mixed dysphagia than solid dysphagia. The clinical utility of a symptomatic differentiation of patients with solid or mixed dyphagia appears to be limited.     

Clinical use of ambulatory 24-hour esophageal motility monitoring in patients with primary esophageal motor disorders

The development of miniaturized electronic pressure transducers and portable digital data recorders with large storage capacity has made ambulatory monitoring of esophageal motor function over an entire circadian cycle possible. Broad clinical application of this new technology in a large number of asymptomatic normal volunteers and patients with symptoms suggestive of a primary esophageal motor disorder provides new insights into esophageal motor function under a variety of physiologic conditions in health and disease. These studies suggest that ambulatory esophageal motility monitoring allows for a more precise classification of esophageal motor disorders than standard manometry and can identify abnormal esophageal motor patterns associated with nonobstructive dysphagia or noncardiac chest pain. Ambulatory esophageal motility monitoring performed in combination with pH monitoring is currently the most physiologic way to assess esophageal function and has potential to improve diagnosis and management of patients with esophageal motor disorders. Ambulatory 24-h esophageal motility monitoring should become the gold standard for assessing motor function of the esophageal body.     

Drug-induced dysphagia

Dysphagia describes the disability or problems in swallowing a wet or dry bolus properly and is normally associated with an impaired transport of the bolus. Dysphagia can be accompanied by a pain sensation in the chest mostly caused by impaction of the food bolus in the esophagus. Odynophagia describes only the status of painful swallowing without an impairment of the swallow and transport function. Drug-induced dysphagia can be caused in two different ways. First as a normal drug side effect of the pharmacological action of the drug or as a complication of the therapeutic action of the drug. The normal drug side effect is most likely in drugs that affect smooth or striated muscle function or the sensitivity of the mucosa. The drug effect on smooth muscle function that causes dysphagia can be inhibitory or excitatory. Dysphagia is a common clinical symptom in patients with reduced perception of the pharyngeal mucosa which leads to an subjective impairment of swallowing. Dysphagia caused by a complication of the therapeutic action of a drug includes viral or fungal esophagitis in patients treated with immunosuppressive drugs or cancer therapeutic agents, or antibiotics and immunological reactions to certain drugs such as erythema exsudativa multiforme or Stevens-Johnson syndrome. Second, drug-induced dysphagia can be due to medication-induced esophageal injury (MIEI). In most cases this mucosal injury appears to be the direct result of prolonged contact of a potentially caustic drug with the esophageal mucosa. This form of medication-induced esophagitis is most likely to be found in elderly patients and patients with esophageal motility disorders. The medication-induced esophageal injury is further promoted by taking the medication at bedtime without enough fluid. In conclusion, drug-induced dysphagia can be caused in many different ways. A carefully taken history in a patient, especially of the current medication, is important for the clinical diagnosis. MIEI can be prevented by concurrent ingestion of adequate amounts of fluid and avoidance of unnecessary bedtime medication, especially in elderly patients.     

Radiographic techniques and efficacy in evaluating esophageal dysphagia

The radiographic examination of the esophagus to determine structural and/or functional causes of dysphagia is best performed with multiple techniques. These include full-column studies to produce distended films with or without the use of a solid bolus, mucosal relief films to identify mucosal defects such as esophagitis or the presence of varices, double-contrast films, and motion recording (fluoroscopy). The efficacy of each technique depends on the quality of the study and the specific disorder to be detected. Esophageal lesions producing dysphagia are classified into extrinsic structural lesions, intrinsic structural lesions, and esophageal motility disorders. Radiographic studies are the preferred screening techniques for patients with dysphagia. Although not as sensitive for the evaluation of mucosal lesions, radiographic studies are superior to endoscopy for the detection of abnormal motility, esophageal rings, and strictures.     

Prevalence of Dysphagia in Patients with Gastroesophageal Reflux in Germany

Dysphagia is an alarming symptom that raises the possibility of stricture or malignancy. This study compares the prevalence and severity of dysphagia symptoms in subjects with or without gastroesophageal reflux (GERD). In a population-based study, 500 residents of Cologne between the ages of 20 and 90 years [232 (46%) males and 268 (54%) females] were randomly selected from the city register and sent questionnaires with reflux-related questions. Two hundred sixty-eight replies (54%) were accepted into the study. Of these, 45% were men with a median age of 58 years. The median female age was 54 years. Thirty-four percent of the respondents (n=92) admitted having heartburn symptoms. There was no significant gender-based difference. There was little variation in reflux frequency between individual age groups. Twenty-three (25%) of the 92 respondents with reflux reported symptoms more than twice per week. Forty-five percent of this "reflux" group took medications for their heartburn. Swallowing difficulties, predominantly mild, were reported in 11.3% of the respondents. Dysphagia was significantly increased in the reflux group (28%) versus the normal group (3%) (p<0.001). Sixteen percent of respondents with mild and 65% of those with moderate to severe reflux symptoms reported additional dysphagia symptoms (p<0.001). Swallowing problems are common in patients with GERD. Approximately two thirds of patients with long-term and severe reflux symptoms also have dysphagia symptoms. Dysphagia should always be investigated by a physician.     

Influence of endoscopic submucosal dissection on esophageal motility

AIM: To assess esophageal motility after esophageal endoscopic submucosal dissection (ESD). METHODS: Twelve patients (6 men and 6 women) aged 53-64 years (mean age, 58 years) who underwent regular examination 3-12 mo after esophageal ESD for neoplasms of the esophageal body were included in this study. The ESD procedure was performed under deep sedation using a combination of propofol and fentanyl, and involved a submucosal injection to lift the lesion and use of a dual-knife and an insulated-tip knife to create a circumferential incision around the lesion extending into the submucosa. Esophageal motility was examined using a high-resolution manometry system. Dysphagia was graded using a five-point scale according to the Mellow and Pinkas scoring system. Patient symptoms and the results of esophageal manometry were then analyzed. RESULTS: Of the 12 patients enrolled, 1 patient hadgrade 2 dysphagia, 1 patient had grade 1 dysphagia, and 3 patients complained of sporadic dysphagia. Ineffective esophageal motility was observed in 5 of 6 patients with above semi-circumference of resection extension. Of these 5 patients, 1 patient complained of grade 2 dysphagia (with esophageal stricture), one patient complained of grade 1 dysphagia, and 3 patients complained of sporadic dysphagia. Normal esophageal body manometry was observed in all 6 patients with below semi-circumference of resection extension. The 6 patients with normal esophageal motility did not complain of dysphagia. CONCLUSION: Extensive esophageal ESD may cause esophageal dysmotility in some patients, and might also have an influence on dysphagia although without esophageal stricture.     

A prospective psychological evaluation of patients with dysphagia of various etiologies

We hypothesized that patients who complain of dysphagia without demonstrable organic abnormality may have an underlying psychological dysfunction. We thus conducted a comprehensive assessment in three groups of patients with dysphagia. Dysphagia was classified as obstructive (Obst) when an obstructive lesion was present on esophagoscopy or barium swallow, motility-related (Mot) when abnormal motility was shown on esophageal manometry in the presence of normal esophagoscopy or barium swallow, or nonobstructive, nonmotility-related (NONM) when manometry and esophagoscopy or barium swallow were both normal. We prospectively evaluated 71 patients with Obst-dysphagia, 15 patients with Mot-dysphagia and 10 patients with NONM-dysphagia with a battery of standardized psychological tests including the Minnesota Multiphasic Personality Inventory (MMPI), the Symptom Checklist-90-Revised (SCL-90-R), and the Millon Behavioral Health Inventory (MBHI). The results indicate that patients with NONM-dysphagia have psychological attributes similar to those found in patients with Obst-dysphagia or Mot-dysphagia. Combination of scores for parameters such as somatization, depression, and anxiety could not distinguish among the three groups of dysphagia patients. We thus conclude that patients with NONM-dysphagia, as a group, have similar psychological profiles compared to patients with dysphagia due to organic causes.     

Epiphrenic Diverticulum: Clinical and Radiographic Findings in 27 Patients

Abstract The purpose of our study was to reassess the clinical and radiographic findings in patients with epiphrenic diverticula. A search of our radiology files revealed 27 patients with epiphrenic diverticula within 10 cm of the gastroesophageal junction. Medical records and radiographic reports and images were reviewed to determine the clinical and radiographic findings. Twenty-three patients had a solitary epiphrenic diverticulum, three had two diverticula, and one had three diverticula. The diverticula arose from the right side of the distal esophagus in 19 patients and the left side in eight. The diverticula had a mean width of 4.4 cm and a mean height of 3.7 cm. Other findings included prolonged retention of barium in the diverticula in 19 patients, preferential filling in 11, retained debris in 5, regurgitation of barium or debris in 5, compression of the esophagus in 5, pseudodiverticula formation in 3, and ulceration in 1. We found a significant correlation between the width of the diverticulum and preferential filling with barium. Twelve patients had abnormal esophageal motility, with diffuse esophageal spasm in two. Seventeen patients had symptoms attributable to the diverticulum (dysphagia in 11 and/or reflux symptoms in 12). We also found a significant correlation between the size or preferential filling of the diverticulum and the presence of symptoms. Conversely, we found no correlation between esophageal dysmotility and the presence of symptoms. Our experience suggests that the development of symptoms in patients with epiphrenic diverticula is more likely to be related to the morphologic features of the diverticula than to underlying esophageal motility disorders.     

Esophageal manometry in systemic sclerosis: screening procedure or confined to symptomatic patients?

The predictive value of esophagus-related symptoms for the diagnosis of esophageal dysmotility induced by systemic sclerosis (SSc) was prospectively evaluated in 50 consecutive patients with SSc. Patients were classified as symptomatic when either dysphagia or repeated episodes of heartburn were present. All patients underwent esophageal manometry; SSc-induced esophageal dysfunction was diagnosed when there was aperistalsis or marked hypocontractility of the distal two-thirds of the esophageal body. Twenty-nine patients (58%) had a history of esophagus-related symptoms, while 21 patients (42%) were asymptomatic. Compared to esophageal manometry, esophagus-related symptoms had a sensitivity of 64%, a specificity of 52%, a negative predictive value of 50% and a positive predictive value of 62% for the diagnosis of SSc-induced esophageal dysfunction. In conclusion, the association of esophagus-related symptoms and esophageal motility pattern is poor. As clinical management strategies depend on proof of esophageal dysfunction, screening examinations are mandatory in all patients with SSc. Received: 30 January 1997 / Accepted: 21 April 1997     

Unexplained dysphagia: Viscous swallow-induced esophageal dysmotility

Dysphagia is a manifestation of several clinical conditions of diverse origin. In spite of the variation in these disease entities in terms of their etiology, clinical presentation, natural history, and treatment, the mechanism of this clinical complaint is not always clear. We studied a group of patients with dysphagia for solids in whom no anatomic or motor abnormalities were encountered on standard studies. The group consisted of 37 patients, 25 women and 12 men, who were complaining of dysphagia of 6 months or longer duration and they did not demonstrate structural or motor abnormalities on barium esophagogram, esophagoscopy, and standard esophageal manometry. A group of 24 age-matched patients, 14 women and 10 men, with noncardiac chest pain served as the patient control. Esophageal contractile activities were studied after 10 wet swallows (5 ml of water) and 10 viscous swallows (5 cubic cm of marshmallow). Resting lower esophageal sphincter pressure and its relaxation response to swallows, amplitude of peristaltic activities, rate of dysphagia provoked during the study, and the frequency of abnormal esophageal contractions were evaluated. Six abnormal esophageal contractile activities—failed peristalsis, dropout, repetitive, simultaneous, spontaneous contractions, and aperistalsis—were utilized to generate an esophageal peristaltic dysfunction index. The mean LESP was 8.1±4.7 in the dysphagia group and 16.1±4.3 in the chest pain group. The mean amplitude of peristaltic contractions was 47.1±16.1 and 89.0±27.0 mmHg after wet swallows for dysphagia and chest pain groups, respectively. These values were 58.2±12.4 and 92.4±22.1 for viscous swallows. Swallowing provoked dysphagia in 89% of the dysphagia group after viscous swallows and 9% after wet swallows. In contrast, only 11% and 3% of control group complained of dysphagia during the study. This group of patients probably represent a cohort of patients with a nonspecific esophageal motor disorder in whom both clinical symptom and their esophageal motor counterpart can only be elicited in response to viscous swallows. We strongly believe in addition of viscous swallows in evaluating dysphagic patients in whom symptoms remain unexplained in light of standard studies.     

A Questionnaire Study to Assess Long-Term Outcome in Patients with Abnormal Esophageal Manometry

Patients with unexplained chest pain or dysphagia are often referred for esophageal manometric studies to further investigate their symptoms. Four main manometric abnormalities have been described: achalasia, diffuse esophageal spasm, “nutcracker” (hypercontracting) esophagus, and hypocontracting esophagus. With the exception of achalasia, treatments are of limited benefit and the natural history of these conditions is largely unknown. We sent questionnaires to patients who were investigated at least three years before our study began. They repeated a DeMeester symptom questionnaire that they had completed at the time of their initial study. Questionnaires were sent to 137 patients with diffuse esophageal spasm, “nutcracker” (hypercontracting) esophagus, or hypocontracting esophagus. We also sent questionnaires to 57 patients with dysphagia or chest pain who had had normal esophageal manometry and pH studies. These patients acted as symptomatic controls. Responses were compared using the Wilcoxon signed ranks test. Seventy-two (53%) patients with diffuse esophageal spasm, “nutcracker” esophagus, or hypocontracting esophagus replied. An additional 8 (6%) patients died. Symptom scores in all three conditions had improved significantly over time (p ≤ 0.01 for each condition, Wilcoxon signed ranks test). Patients with dysphagia or chest pain but normal esophageal studies had not improved. The significance of diffuse esophageal spasm, “nutcracker” esophagus, and hypocontracting esophagus found at esophageal manometry remains uncertain. Although treatment is often ineffective, these conditions typically run a benign course. Patients can be reassured that their symptoms are likely to improve with time.     

An appraisal of current dysphagia diagnosis and treatment strategies

Dysphagia is a common, serious health problem with a wide variety of etiologies and manifestations. This review gives a general overview of diagnostic and therapeutic options for oropharyngeal as well as esophageal swallowing disorders respecting the considerable progress made over recent years. Diagnosis can be challenging and requires expertise in interpretation of symptoms and patient history. Endoscopy, barium radiography and manometry are still the diagnostic mainstays. Classification of esophageal motor-disorders has been revolutionized with the introduction of high-resolution esophageal pressure topography and a new standardized classification algorithm. Automated integrated impedance manometry is a promising upcoming tool for objective evaluation of oropharyngeal dysphagia, in non-obstructive esophageal dysphagia and prediction of post fundoplication dysphagia risk. Impedance planimetry provides new diagnostic information on esophageal and LES-distensibility and allows controlled therapeutic dilatation without the need for radiation. Peroral endoscopic myotomy is a promising therapeutic approach for achalasia and spastic motility disorders.     

Ineffective oesophageal motility： Manometric subsets exhibit different symptom profiles

AIM： To compare the demographic and clinical features of different manometric subsets of ineffective oesophageal motility （IOM; defined as ≥ 30% wet swallows with distal contractile amplitude 〈 30 mmHg）, and to determine whether the prevalence of gastro-oesophageal reflux differs between IOM subsets.
METHODS： Clinical characteristics of manometric subsets were determined in 100 IOM patients （73 female, median age 58 years） and compared to those of 100 age-and gender-matched patient controls with oesophageal symptoms, but normal manometry. Supine oesophageal manometry was performed with an eight-channel DentSleeve water-perfused catheter, and an ambulatory pH study assessed gastrooesophageal reflux.
RESULTS： Patients in the IOM subset featuring a majority of low-amplitude simultaneous contractions （LASC） experienced less heartburn （prevalence 26%）, but more dysphagia （57%） than those in the IOM subset featuring low-amplitude propagated contractions （LAP; heartburn 70%, dysphagia 24%; both P ≤ 0.01）. LASC patients also experienced less heartburn and more dysphagia than patient controls （heartburn 68%, dysphagia 11%; both P 〈 0.001）. The prevalence of heartburn and dysphagia in IOM patients featuring a majority of non-transmitted sequences （NT） was 54% （P = 0.04 vs LASC） and 36% （P 〈 0.01 vs controls）, respectively. No differences in age and gender distribution, chest pain prevalence, acid exposure time （AET） and symptom/reflux association existed between IOM subsets, or between subsets and controls.
CONCLUSION： IOM patients with LASC exhibit a different symptom profile to those with LAP, but do not differ in gastro-oesophageal reflux prevalence. These findings raise the possibility of different pathophysiological mechanisms in IOM subsets, which warrants further investigation.     

The Evaluation of Dysphagia after Anterior Cervical Spine Surgery: A Case Report

The anterior approach to cervical spine surgery is associated with many possible complications. Dysphagia has commonly been reported as one of these complications. A closer examination of the reports of dysphagia following anterior cervical spine surgery, however, reveals that while new onset transient dysphagia is often mentioned, long-term (greater than 48 hours) dysphagia has not been well described. In this article, we report the case of a 29-year-old female with long-term recurrent dysphagia following cervical spine surgery using the anterior approach. The important point about this case is that our patients symptoms suddenly recurred for the first time after nearly a two-month period of normal swallowing. Consequently, this patient has required multiple dilations. As a result, despite an initial lack of swallowing dysfunction or the return of normal swallowing, clinicians should be aware of the importance of reassessing swallowing in patients who have undergone cervical spine surgery using the anterior approach.     

Dysphagia in aging

Dysphagia is a common problem in older patients and is becoming a larger health care problem as the populations of the United States and other developed countries rapidly age. Changes in physiology with aging are seen in the upper esophageal sphincter and pharyngeal region in both symptomatic and asymptomatic older individuals. Age related changes in the esophageal body and lower esophageal sphincter are more difficult to identify, while esophageal sensation certainly is blunted with age. Stroke, Parkinson's disease, amyotrophic lateral sclerosis, Zenker's diverticula, and several other motility and structural disorders may cause oropharyngeal dysphagia in an older patient. Esophageal dysphagia can also be caused by both disorders of motility (achalasia, diffuse esophageal spasm, scleroderma and others) and structure (malignancy, strictures, rings, external compression, and others). Many of these disorders have an increased prevalence in older patients and should be sought with an appropriate diagnostic evaluation in older patients. The treatment of dysphagia in older patients is similar to that in younger patients, but more invasive therapies such as surgery may not be possible in some older patients making less aggressive medical and endoscopic therapy more attractive.     

Effects of a multidisciplinary management program on neurologically impaired patients with dysphagia

Dysphagia is a major problem in patients with neurologic disorders. Aspiration pneumonia and impaired nutritional status are consequences of dysphagia that result in high morbidity and mortality rates [1, 2]. Assessment and treatment of the dysphagic patient by a multidisciplinary team have been advocated but to date the effects of such an approach have not been demonstrated quantitatively. This prospective study was conducted to determine if a dysphagia program would improve patients' caloric intake and body weight, decrease the instances of aspiration pneumonia, or improve patients' feeding ability. Patients were referred from a 26 bed neurology/neurosurgery unit. A time series design was utilized. The control group consisted of 15 patients (mean age=46.1 years), managed according to the existing ward routine. Subsequently, nursing staff attended a dysphagia training program. Following this, the treated group of 16 patients, (mean age=49.3 years) was assessed by the dysphagia team, using bedside and videofluoroscopic examinations to determine the specific swallowing disorder. An individualized treatment program was designed for each patient. The groups were compared on the basis of deviation from their baseline weight, deviation from ideal energy intake, and the incidence of aspiration pneumonia. Statistical analysis revealed that the groups were comparable in age, number of days on the study, and Glasgow Coma Scale score; and that a significant weight gain and increase in caloric intake occurred in the treated group. No incidence of aspiration pneumonia was reported in either group. We speculate that this may have been influenced by the meticulousness of the care delivered in an acute unit as well as greater attention to prevention given in both groups. We conclude that the institution of a multidisciplinary team to manage dysphagia resulted in improvement in patients' weight and caloric intake.     

Irreversible Esophageal Motor Dysfunction in Postvagotomy Dysphagia

Postvagotomy dysphagia is typically a temporary phenomenon but a small subgroup of patients appear to develop irreversible motility disorders of the esophagus. Two patients are reported with persistent symptomatic esophageal dysfunction demonstrated by modern hydraulic infusion technics. Both intially lost weight rapidly and then stabilized. The distal esophagus of both was greatly dilated but in one patient, lower esophageal sphincter pressure was normal. Aperistalsis with diminished motor activity was present throughout the body of the esophagus. Dysphagia and objective esophageal abnormalities were refractory to dilations with simple mercury bougies in one patient whose condition was improved by treatment with pneumatic dilation. The cause of this unusual complication is unknown but may involve a nonneoplastic form of secondary achalasia.     

A neglected symptom of contained aortic laceration—Dysphagia aortica successfully treated by endovascular stentgrafting

Purpose : Dysphagia aortica describes an esophageal swallowing disorder caused by external compression from an ectatic, tortuous, or aneurysmal thoracic aorta. Although well recognized among specialists, dysphagia aortica is rarely considered in the differential diagnosis of dysphagia. Case Report : We present the case of a 75‐year‐old woman with a history of swallowing difficulty and retrosternal pressure sensation. Her symptoms had been attributed to sliding axial hernia along with gastroesophageal reflux disease for the last 12 months. Diagnostic workup at our institution revealed a giant penetrating ulcer of the descending aorta as a culprit of esophageal compression. Expeditious endovascular stentgraft exclusion of the aneurysm was performed because of its symptomatic nature and high propensity of spontaneous rupture. On a recent consultation 2 years after the endovascular procedure, the patient confirmed a complete remission of impaired swallowing and freedom from thoracic discomfort. Conclusions : Dysphagia aortica should be considered in the numerous differential diagnoses of esophageal swallowing disorders in the elderly, as delayed identification may harbor catastrophic outcome for affected individuals. © 2011 Wiley Periodicals, Inc.
