RESUMO
BACKGROUND: Cricopharyngeal myotomy improves pharyngeal dysphagia by resecting the cricopharyngeal muscle. METHODS: Our procedure, cricopharyngeal muscle origin transection (CPM-OT) is performed through a midline skin incision at the cricoid cartilage level under local anesthesia. CONCLUSIONS: Sixteen patients demonstrated preservation of vocal fold movement without laryngeal nerve injury immediately after CPM-OT in the awake state during aspiration prevention surgery using the glottic closure technique. Postoperative videofluoroscopic examination of swallowing revealed the cricopharyngeal bar was absent and pharyngeal passage of the bolus and Food Intake LEVEL Scale was improved in all patients. CPM-OT is a feasible and less invasive treatment option.

OBJECTIVE: To investigate the impact of dysphagia on long-term survival and swallowing function outcomes in patients with idiopathic inflammatory myopathy other than inclusion body myositis. METHODS: We retrospectively evaluated consecutive patients with idiopathic inflammatory myopathy other than inclusion body myositis to investigate the impact of dysphagia and its severity assessed using the Food Intake LEVEL Scale on survival and swallowing function outcomes. Time-to-event analyses were used, including Kaplan-Meier curves with log-rank (trend) test, cumulative incidence with Gray's test, and Cox proportional hazards models. RESULTS: Of the 254 patients, 26 were dysphagic, including eight severe (Food Intake LEVEL Scale [FILS] score 2, 3) and six most severe (FILS score 1) cases; 210 were non-dysphagic, and 18 were indeterminate cases. During the 5 years after myositis diagnosis, 15 (57.7%) dysphagic and 31 (14.8%) non-dysphagic patients died, and dysphagic patients had significantly shorter survival. However, multivariate analysis showed that shorter survival was significantly associated with baseline age-adjusted Charlson Comorbidity Index (hazard ratio [HR] 1.57, 95% confidence interval [CI] 1.36-1.82]), but not with dysphagia (HR 1.46, 95% CI 0.69-3.10). Dysphagia severity was significantly associated with delayed recovery of dysphagia. In 20 non-severe or severe dysphagic cases, 19 restored swallowing function within 1 year. The most severe cases had a significantly higher cumulative probability of death before recovery from dysphagia than severe cases. CONCLUSION: The poor survival of dysphagic myositis patients was largely confounded by advanced age and comorbid malignancies. However, patients with the most severe dysphagia had a significantly worse swallowing function and survival prognosis than those with milder dysphagia.

Despite the clinical impact of dysphagia in myasthenia gravis (MG), a standard protocol for diagnosing dysphagia reliably has not yet been established. High-resolution manometry (HRM) provides precise information on pharyngeal pressure. We hypothesized that swallowing pressure assessment using HRM during the edrophonium chloride (EC) test could identify mild bulbar symptoms with no abnormalities on videoendoscopic (VE) and videofluorographic (VF) examination of swallowing, and we tested this hypothesis on a 72-year-old female patient diagnosed with ocular MG who developed slight pharyngeal discomfort over 3 months. The patient's ocular symptoms were stable with pyridostigmine medication. VE and VF revealed no abnormalities. The swallowing pressure along the pharynx was measured using HRM during the EC test. HRM parameters, including velopharyngeal contractile integral and meso-hypopharyngeal contractile integral, were evaluated. These parameters were assessed for three swallows using 3 mL of water. After EC injection, the values of the velopharyngeal contractile integral (78.0 ± 5.4 vs. 134.7 ± 1.3 mm Hg cm·s) and the meso-hypopharyngeal contractile integral were both higher (130.6 ± 1.5 vs. 284.2 ± 11.9 mm Hg cm·s) than those observed before EC injection. Chest computed tomography revealed a thymoma that had not been observed in previous examinations. The patient was diagnosed with thymoma-associated MG. Intravenous immunoglobulin therapy improved the mild dysphagia. We concluded that swallowing pressure assessment during the EC test may be helpful in identifying mild bulbar symptoms in patients with MG.
RESUMO
The simple suspension method (SSM), developed by Kurata in 1997, is a way to suspend tablets and capsules in warm water for decay and suspension prior to their administration. This method is safe and has various advantages such as the avoidance of tube clogging and the loss of the drug. This study aimed to investigate whether a higher percentage of commonly used drugs could pass through nutrition tubes effectively using SSM, relative to that using the conventional crushing method. A tablet or capsule was inserted into a 20 mL syringe with warm water (at 55 °C). After 10 min, it was shaken in the syringe. The suspension liquid was injected into tubes of the following sizes: 8 Fr, 10 Fr, 12 Fr, 14 Fr, 16 Fr, and 18 Fr. A total of 3686 tablets and 432 capsules that are frequently used in Japan were tested. Using SSM, 3377 (91.6%) tablets and 359 (83.1%) capsules disintegrated within 10 min and passed through the tube without clogging it in the tube passage test. With the conventional crushing method, 2117 tablets (57.4%) and 272 capsules (63.0%) could be crushed. SSM reduced the risk of tube clogging and drug loss with more drugs than that with the conventional crushing method. The number of drugs indicated for administration by SSM is greater than that indicated by the conventional crushing method. Further studies are needed to consider its utility compared to conventional methods for dysphagia patients in clinical settings.

Patient Palatal lift prostheses (PLPs) are used for dysarthria caused by velopharyngeal incompetence (VPI) and improving hypernasal speech. In this case, we used a PLP with a flexible lift (f-PLP) in a patient with dysphagia associated with VPI due to right-sided cranial nerve injuries after a skull base surgery. We examined its efficacy in swallowing biomechanics and swallowing function using high-resolution manometry (HRM) and videofluoroscopic examination of swallowing (VF). The patient felt that it was easier to swallow with f-PLP. Furthermore, VF indicated that the pharyngeal residue with f-PLP was less than without it. HRM showed that velopharyngeal pressure and intrabolus pressure (IBP) with f-PLP were higher than those without it. Additionally, the upper esophageal sphincter (UES) relaxation time and UES nadir pressure on the patient's healthy left side compared to the right side improved with f-PLP.Discussion We discovered two clinical outcomes. First, the f-PLP ensured velopharyngeal closure and an increase in the hypopharyngeal IBP, which potentially improved the UES opening on the healthy side. Second, the f-PLP improved pharyngeal clearance, and the patient felt that it was easier to swallow with the f-PLP. This implies that an f-PLP potentially exhibits a positive effect on swallowing.Conclusions In this case, the f-PLP contributed to improving the pharyngeal passage of a bolus. We suggest that f-PLPs can be used for patients with dysarthria and those with dysphagia with VPI.

Recently, there has been clinical interest in the effect of different body positions on esophageal motility. This study aimed to identify the effect of three different body positions on esophageal motility using high-resolution manometry. Thirteen healthy adults swallowed 5 mL of water in the upright, supine, and bridge positions. For the bridge position, each subject raised their waist against gravity, placed a cushion under their back, and bent their knees. The proximal contractile integral (PCI) and distal contractile integral (DCI), integrated relaxation pressure (IRP), distal latency (DL), peristaltic breaks (PBs), intrabolus pressure (IBP), and expiratory and inspiratory esophagoesophageal junction (EGJ) pressure were measured. In the bridge position, PCI, DCI, IRP, and expiratory and inspiratory EGJ pressure were significantly higher than those in the upright position (bridge PCI vs. upright PCI [p = 0.001], bridge DCI vs. upright DCI [p < 0.001], bridge IRP vs. upright IRP [p = 0.018], bridge EGJ pressure vs. upright EGJ pressure [expiratory: p = 0.001] [inspiratory: p < 0.001]). PBs were significantly shorter and DL was significantly longer in the bridge position compared to upright (bridge PBs vs. upright PBs [p = 0.001], bridge DL vs. upright DL [p = 0.001]). IBP was significantly higher in the bridge position compared to supine (bridge IBP vs. supine IBP [p = 0.01]). These results demonstrated changes in esophageal motility according to changes in position while swallowing, where esophageal contractions became stronger against gravity. Further study is required to examine the effectiveness of swallowing in the bridge position.
