Oesophageal motility disorders in patients with psychiatric disease

Medically Unexplained Oropharyngeal Dysphagia at the University Hospital ENT Outpatient Clinic for Dysphagia: A Cross-Sectional Cohort Study

Medically unexplained oropharyngeal dysphagia (MUNOD) is a rare condition. It presents without demonstrable abnormalities in the anatomy of the upper aero-digestive tract and/or swallowing physiology. This study investigates whether MUNOD is related to affective or other psychiatric conditions. The study included patients with dysphagic complaints who had no detectible structural or physiological abnormalities upon swallowing examination. Patients with any underlying disease or disorder that could explain the oropharyngeal dysphagia were excluded. All patients underwent a standardized examination protocol, with FEES examination, the Hospital Anxiety and Depression Scale (HADS), and the Dysphagia Severity Scale (DSS). Two blinded judges scored five different FEES variables. None of the 14 patients included in this study showed any structural or physiological abnormalities during FEES examination. However, the majority did show abnormal piecemeal deglutition, which could be a symptom of MUNOD. Six patients (42.8%) had clinically relevant symptoms of anxiety and/or depression. The DSS scores did not differ significantly between patients with and without affective symptoms. Affective symptoms are common in patients with MUNOD, and their psychiatric conditions could possibly be related to their swallowing problems.

Dysphagia in a psychotic patient: Diagnostic challenges and a systematic management approach

Dysphagia can be due to a variety of causes in a psychotic patient. It could be a side-effect of anti-psychotic medication or the manifestation of a psychotic phenomenon or even due to a co-morbid medical cause. We report a case of dysphagia in a young lady with psychosis who had been recently started on anti-psychotic medication. We would specifically like to highlight the practical challenges regarding its diagnosis and report success with a systematic management approach.

Aging and intestinal motility: a review of factors that affect intestinal motility in the aged

Normal aging is associated with significant changes in the function of most organs and tissues. In this regard, the gastrointestinal tract is no exception. The purpose of this review is to detail the important age-related changes in motor function of the various parts of the gastrointestinal tract and to highlight some of the important motility changes that may occur, either in relation to common age-related disorders, or as a result of certain drugs commonly prescribed in the aged. A major confounding factor in the interpretation of motor phenomena throughout the gastrointestinal tract in this age group is the frequent coexistence of neurological, endocrinological and other disease states, which may be independently associated with dysmotility. Overall, current data are insufficient to implicate normal aging as a cause of dysmotility in the elderly. Normal aging is associated with various changes in gastrointestinal motility, but the clinical significance of such changes remains unclear. More important is the impact of various age-related diseases on gastrointestinal motility in the elderly: for example, long-standing diabetes mellitus may reduce gastric emptying in up to 50% of patients; depression significantly prolongs whole-gut transit time; hypothyroidism may prolong oro-caecal transit time; and chronic renal failure is associated with impaired gastric emptying. In addition, various, frequently used drugs in the elderly cause disordered gastrointestinal motility. These drugs include anticholinergics, especially antidepressants with an anticholinergic effect, opioid analgesics and calcium antagonists.

Inconsistent association of esophageal symptoms, psychometric abnormalities and dysmotility

OBJECTIVES

The aim of this study was to characterize the psychometric profiles of symptomatic patients with abnormal esophageal motility and symptomatic patients with normal manometric findings compared to asymptomatic controls.

METHODS

A total of 113 patients with abnormal esophageal motility (7 achalasia, 8 diffuse esophageal spasm, 27 nutcracker esophagus, 37 hypertensive lower esophageal sphincter, 21 hypotensive peristalsis, 13 failed peristalsis), 23 symptomatic controls with similar esophageal symptoms but normal manometry, and 27 asymptomatic controls were enrolled. Validated questionnaires assessing depression (Beck Depression Inventory), anxiety (Spielberger State Anxiety Inventory or Trait Anxiety Inventory), and somatization (Psychosomatic Symptom Checklist) were administered to all subjects.

RESULTS

Patients with both esophageal symptoms and either hypertensive lower esophageal sphincter, nutcracker esophagus, or hypotensive contractions exhibited increased somatization, acute anxiety, or depression compared to asymptomatic controls but not compared to symptomatic controls. On the other hand, the psychometric profiles of patients with achalasia and diffuse esophageal spasm were strikingly normal. Among esophageal symptoms, chest pain was closely correlated with psychometric abnormalities.

CONCLUSIONS

The esophageal symptoms of patients with abnormal esophageal motility may relate to the underlying psychological abnormalities, independent of manometric abnormalities.

A physiological manoeuvre to improve the positivity of the gastro-oesophageal reflux scintigraphic test

One of the best examinations used routinely to detect gastro-oesophageal reflux (GOR) is scintigraphy and attempts are continuously being made to improve the performance of the test. We have tested a new manoeuvre to improve the results. Three hundred and twenty eight patients (190 males and 138 females, aged 1 month to 84 years, average 4.47 years) were studied after a 12 h fast period with 100 MBq of 99Tcm-phytate, 50 ml volume, directly delivered into the stomach in a mixture of orange juice. All patients were strongly suspected of having GOR. Conventional acquisition was done for 20 min, at a rate of one frame every 20 s. In the middle of the examination, small children were put in the upright position and held there for a few seconds or released in a way that allowed movement; adults were asked to stand up and walk a few metres. The test was then continued for the remaining 10 min. The global index of positivity was 64.6% (76 positive cases in the first half of the examination and 134 positive cases only after the manoeuvre). The mean of GOR episodes observed in the positive cases without the manoeuvre was 0.5 per patient, significantly different from the mean of 1.59 noted after the manoeuvre (P<0.01). In 28 cases the manoeuvre increased either the intensity or the frequency of reflux previously detected without it. We believe that this manoeuvre should be performed in all scintigraphic tests aiming to detect GOR. In the present series, the manoeuvre increased the frequency of GOR episodes.
