Abstract
Over the years, our growing experience with endoscopic submucosal dissection along with technological advances has solidified our comfort and knowledge on working in the submucosa, also referred to as the "third space." Per-oral endoscopic myotomy (POEM) was the first prototype third-space endoscopy (TSE) procedure, demonstrating the feasibility and clinical utility of endoscopic esophagogastric myotomy via submucosal tunneling. The launch of POEM accelerated the evolution of TSE from a vanguard concept to an expanding field with a wide range of clinical applications. In this review, we discuss the status and future directions of multiple TSE interventions.

Abstract
BACKGROUND Cricopharyngeal bars (CPBs) are a unique etiology of oropharyngeal dysphagia. Symptomatic patients are managed with endoscopic dilation or surgical myotomy. Cricopharyngeal peroral endoscopic myotomy (CP-POEM) is an emerging technique for the management of dysphagia due to CPBs. This study evaluated technical success, clinical success, adverse events, and long-term recurrence following CP-POEM. METHODS Consecutive patients who underwent POEM for management of CPBs between May 2015 and December 2020 at four tertiary care centers were included. Primary outcome was clinical success (defined as improvement of dysphagia score to ≤ 1). Secondary outcomes were technical success, rate and severity of adverse events, procedure duration, and symptom recurrence. RESULTS 27 patients (mean age 69 years; 10 female) underwent CP-POEM during the study period. The most common presenting symptoms at the time of index procedure were dysphagia (26; 96.3 %) and regurgitation (20; 74.1 %). Clinical and technical success were achieved in all patients. Mild/moderate adverse events occurred in two patients (7.4 %). CP-POEM significantly reduced the median dysphagia score. CONCLUSIONS CP-POEM was a safe and effective treatment for symptomatic CPBs. Although symptom recurrence was low, long-term outcome data are needed. CP-POEM should be considered as a management option for symptomatic CPBs at centers with POEM expertise.

Abstract
Importance The incidence of Zenker diverticulum has been established; previous estimates have been extrapolated from small institutional cohorts. Objective To describe the population-wide incidence of Zenker diverticulum over a 20-year period and characterize management strategies across specialties and treatment settings. Design, Setting, and Participants This retrospective national cohort study was conducted from January 1, 1996, through December 31, 2015, and reviewed patient records from the Care Register for Healthcare in Finland, from which patients with Zenker diverticulum were identified. The data were analyzed in October 2021. Exposures Zenker diverticulum. Main Outcome and Measure The incidence of Zenker diverticulum per 100 000 person-years. Results A total of 2736 patients (median [IQR] age at diagnosis 72.0 [19-106] years; 1278 women [46.7%]) were identified, making the annual incidence of Zenker diverticulum in Finland 2.9/100 000 person-years. Men had higher incidence (3.7/100 000 person-years) compared with women (2.3/100 000 person-years), with an incidence rate ratio of 1.61 (95% CI, 1.48-1.76; P < .001). Within the study population, 1044 patients (38.2%) underwent surgical treatment and 227 (8.3%) underwent 2 or more surgeries. The choice of initial operative approach depended on the medical specialty (Cramer V = 0.41) and on specific catchment area (Cramer V = 0.41). Overall, endoscopic approaches for initial operations were most popular. Conclusions and Relevance The cohort study results found that the incidence of Zenker diverticulum was 2.9/100 000 person-years. Most patients with Zenker diverticulum did not undergo definitive therapy. Some hospital districts and some medical specialties were more likely to opt for conservative treatment than others. The choice of operative approach depended more on physician-level factors rather than patient profiles.

Abstract
Swallow is a complex behavior that consists of three coordinated phases: oral, pharyngeal, and esophageal. Esophageal distension (EDist) has been shown to elicit pharyngeal swallow, but the physiologic characteristics of EDist-induced pharyngeal swallow have not been specifically described. We examined the effect of rapid EDist on oropharyngeal swallow, with and without an oral water stimulus, in spontaneously breathing, sodium pentobarbital anesthetized cats (n = 5). Electromyograms (EMGs) of activity of 8 muscles were used to evaluate swallow: mylohyoid (MyHy), geniohyoid (GeHy), thyrohyoid (ThHy), thyropharyngeus (ThPh), thyroarytenoid (ThAr), cricopharyngeus (upper esophageal sphincter: UES), parasternal (PS), and costal diaphragm (Dia). Swallow was defined as quiescence of the UES with overlapping upper airway activity, and it was analyzed across three stimulus conditions: 1) oropharyngeal water infusion only, 2) rapid esophageal distension (EDist) only, and 3) combined stimuli. Results show a significant effect of stimulus condition on swallow EMG amplitude of the mylohyoid, geniohyoid, thyroarytenoid, diaphragm, and UES muscles. Collectively, we found that, compared to rapid cervical esophageal distension alone, the stimulus condition of rapid distension combined with water infusion is correlated with increased laryngeal adductor and diaphragm swallow-related EMG activity (schluckatmung), and post-swallow UES recruitment. We hypothesize that these effects of upper esophageal distension activate the brainstem swallow network, and function to protect the airway through initiation and/or modulation of a pharyngeal swallow response.

Abstract
BACKGROUND Idiopathic inflammatory myopathies (IIM) are immune-mediated conditions that affect striated muscle, and are frequently associated with dysphagia. Dysphagia in these cases can be due to weakness of the muscles involved in swallowing or the presence of restrictive pharyngeal defects, such as cricopharyngeal bars. Treatment of dysphagia in IIM revolves around immunosuppressive therapies, and procedures to disrupt cricopharyngeus muscle when immunosuppressive therapies are unsuccessful. CASE REPORT A 73-year-old female presented with rapidly progressive proximal muscle weakness and dysphagia to the point she could not swallow liquids or solids. She had a rash over the extensor surfaces of the limbs, and periorbital-edema. Her creatine kinase was elevated, and skin biopsy showed an interface inflammatory reaction; however, myositis line assay revealed no autoantibodies, and a muscle biopsy was unremarkable. She was diagnosed with dermatomyositis with life-threatening dysphagia, and was admitted to our institution and treated with corticosteroids, methotrexate and intravenous immunoglobulin. A videofluoroscopic swallowing study revealed a large esophageal protrusion at the level of C5-C6, which was thought to be consistent with a cricopharyngeal bar, with large boluses unable to pass, leading to aspiration. After 10 weeks of treatment, the cricopharyngeal bar remained present, but swallowing had improved to the point that she was successfully swallowing all consistencies. CONCLUSION Dysphagia associated with IIM can be multifactorial, and can be due to the involvement of the muscles of swallowing in the inflammatory process, or due to restrictive pharyngeal defects, and determination of the cause of dysphagia can assist with management.

Endoscopic mucosal incision and muscle interruption (MIMI) for the treatment of Zenker's diverticulum. Surg Endosc 2020; 35:3896-3904.

Abstract
BACKGROUND In peroral endoscopic myotomy for Zenker's diverticulum (Z-POEM), the cricopharyngeus muscle is divided within a submucosal tunnel started in the hypopharynx. We aimed to evaluate the safety and preliminary outcomes in patients who underwent a modified version of the Z-POEM where the tunnel is made directly overlying the cricopharyngeus, the mucosal incision and muscular interruption (MIMI) approach, and to compare these with patients who underwent a non-tunneled flexible endoscopic approach. METHODS All patients with ZD who were treated by flexible endoscopy at our institution between January 2015 and February 2020 were identified by a retrospective chart review. Dysphagia symptoms were assessed using a validated scoring system. RESULTS Nineteen patients with ZD underwent MIMI (mean age 76.1 years, 68.1% male) and seven patients underwent non-tunneled flexible endoscopic approach (mean age 64.4 years, 85.7% male) during the study period. Mean ZD size was 2.8 cm in the MIMI group and 1.9 cm in the non-tunneled group (p = 0.03). Clinical success was achieved in 17/19(89.5%) MIMI patients and 7/7(100%) of non-tunneled flexible endoscopic patients (p = 0.101). Dysphagia scores improved in both groups, although this difference was only significant in the MIMI group (p ≤ 0.001). Recurrence occurred in 2/17(11.7%) MIMI patients and 3/7(42.9%) non-tunneled flexible endoscopic patients (p = 0.096). There were 4 complications, including one pharyngeal perforation requiring open surgical repair in a patient with a small ZD with an associated cricopharyngeal bar in the MIMI group. Median length of follow-up was 290 [142; 465] days in the MIMI group and 1056 [258; 1206] days in the non-tunneled group (p = 0.094). CONCLUSIONS MIMI is a technically feasible and effective treatment for ZD. Care should be taken in patients with a cricopharyngeal bar and small ZD, as this may increase the risk of perforation. Larger studies with long-term follow-up are needed to determine if MIMI reduces the risk of symptom recurrence when compared to non-tunneled flexible endoscopic approaches.

Abstract
Dysphagia is a common clinical feature of lateral medullary syndrome (LMS) and is clinically relevant because it is related to aspiration pneumonia, malnutrition, increased mortality, and prolonged hospital stay. Herein, the pathophysiology, prognosis, and treatment of dysphagia in LMS are reviewed. The pathophysiology, prognosis, and treatment of dysphagia in LMS are closely interconnected. Although the pathophysiology of dysphagia in LMS has not been fully elucidated, previous studies have suggested that the medullary central pattern generators coordinate the pharyngeal phases of swallowing. Investigation of the extensive neural connections of the medulla oblongata is important in understanding the pathophysiologic mechanism of dysphagia in LMS. Previous studies have reported that most patients with dysphagia in LMS have a relatively good prognosis. However, some patients require tube feeding for several months, even years, due to severe dysphagia, and little has been reported about conditions associated with a poor prognosis of dysphagia in LMS. Concerning specific therapeutic modalities for dysphagia in LMS, in addition to general modalities used for dysphagia treatment in stroke patients, non-invasive modalities, including repetitive transcranial magnetic stimulation and transcranial direct current stimulation, as well as invasive modalities, such as botulinum toxin injection, balloon catheter dilatation, and myotomy for relaxation of the cricopharyngeal muscle, have been applied. For the appropriate application of therapeutic modalities, clinicians should be aware of the recovery mechanisms and prognosis of dysphagia in LMS. Further studies on this topic, as well as studies involving large numbers of subjects on specific therapeutic modalities, should be encouraged.

Abstract
These are updated guidelines which supersede the original version published in 2004. This work has been endorsed by the Clinical Services and Standards Committee of the British Society of Gastroenterology (BSG) under the auspices of the oesophageal section of the BSG. The original guidelines have undergone extensive revision by the 16 members of the Guideline Development Group with representation from individuals across all relevant disciplines, including the Heartburn Cancer UK charity, a nursing representative and a patient representative. The methodological rigour and transparency of the guideline development processes were appraised using the revised Appraisal of Guidelines for Research and Evaluation (AGREE II) tool.Dilatation of the oesophagus is a relatively high-risk intervention, and is required by an increasing range of disease states. Moreover, there is scarcity of evidence in the literature to guide clinicians on how to safely perform this procedure. These guidelines deal specifically with the dilatation procedure using balloon or bougie devices as a primary treatment strategy for non-malignant narrowing of the oesophagus. The use of stents is outside the remit of this paper; however, for cases of dilatation failure, alternative techniques-including stents-will be listed. The guideline is divided into the following subheadings: (1) patient preparation; (2) the dilatation procedure; (3) aftercare and (4) disease-specific considerations. A systematic literature search was performed. The Grading of Recommendations Assessment, Develop-ment and Evaluation (GRADE) tool was used to evaluate the quality of evidence and decide on the strength of recommendations made.

Abstract
Background Cricopharyngeus muscle dysfunction (CPMD) is a common cause of dysphagia. We employ a progressive series of three double-balloon dilations separated by 4–6 weeks between procedures as a primary treatment option. The purpose of this study was to evaluate subjective, functional and objective improvement in swallowing after three serial dilations for CPMD. Methods We retrospectively evaluated patients between June 1, 2014, and June 30, 2016, who underwent a series of three double-balloon dilations for CPMD. Pre- and post-dilation Eating Assessment Tool-10 (EAT-10), Functional Oral Intake Scale (FOIS), pharyngeal constriction ratio, pharyngeal area, and pharyngoesophageal segment (PES) opening were compared. Results Seventeen patients with CPMD underwent serial double-balloon dilation procedures separated by one month. Mean age of the cohort was 73.5 (SD ± 13.3) years, and 53% were female. The mean EAT-10 improved from 24.7 (SD ± 7.8) to 15.9 (SD ± 10.2) [p = 0.0021]. Mean FOIS improved from 5.4 (SD ± 1.4) pre- to 6.3 (SD ± 0.9) post-treatment (p = 0.017). Mean UES opening increased from 1.05 (SD ± 0.34) cm to 1.48 (SD ± 0.41) cm (p = 0.0003) in the anteroposterior fluoroscopic view and from 0.58 (SD ± 0.18) to 0.76 (SD ± 0.30) cm (p = 0.018) in the lateral view. Pharyngeal constriction ratio (PCR), a surrogate measure of pharyngeal strength, improved from 0.49 (SD ± 0.37) to 0.24 (SD ± 0.15) (p = 0.015), however pharyngeal area (PA) was unchanged. Conclusions A progressive series of three double-balloon dilations for cricopharyngeus muscle dysfunction resulted in improved patient reported dysphagia symptom scores and objective fluoroscopic swallowing parameters.

Abstract
Although the modified balloon dilatation therapy has been demonstrated to improve pharyngeal swallowing function post stroke, the underlying neural mechanisms of improvement are unknown. Our aims are (1) to investigate the effect of modified balloon dilatation on the excitability of corticobulbar projections to the submental muscle in dysphagic patients with brainstem stroke and (2) the relation between changes in excitability and pharyngeal kinematic modifications. Thirty patients with upper esophageal sphincter (UES) dysfunction due to unilateral brainstem stroke were recruited into two groups. The patients in dilatation group received modified balloon dilatation and conventional therapies, and those in control were only treated by conventional therapies (twice per day). The amplitudes of bilateral submental motor evoked potentials (MEPs) induced by transcranial magnetic stimulations over bilateral motor cortex, diameters of UES opening (UOD) and maximal displacement of hyoid (HD) were all assessed at baseline and the endpoint of treatments. Repeated ANOVA analysis revealed significant main effect of group, time and MEP laterality on MEP amplitudes (p = 0.02). There were no differences in the pretreatment measures between groups (all p > 0.05). After treatment, the amplitudes of affected submental MEP evoked by ipsilateral cortical pulse as well as UOD and HD were significantly different in dilatation group compared to control (amplitude: p = 0.02, UOD: p < 0.001, HD: p = 0.03). The differences of pre- and post-treatment amplitudes of the affected MEP evoked by ipsilateral stimulation showed a positive correlation with the improvement of HD (dilatation: R 2 = 0.51, p = 0.03; control: R 2 = 0.39, p = 0.01), rather than UOD in both groups (all p > 0.05). In conclusion, modified balloon dilatation therapy can increase the excitability of affected projection in patients with unilateral brainstem stroke.

Abstract
AIM To evaluate the safety and efficacy of upper esophageal sphincter (UES) dilatation for cricopharyngeal (CP) dysfunction. To determine if: (1) indication for dilatation; or (2) technique of dilatation correlated with symptom improvement.
METHODS All balloon dilatations performed at our institution from over a 3-year period were retrospectively analyzed for demographics, indication and dilatation site. All dilatations involving the UES underwent further review to determine efficacy, complications, and factors that predict success. Dilatation technique was separated into static (stationary balloon distention) and retrograde (brusque pull-back of a fully distended balloon across the UES).
RESULTS Four hundred and eighty-eight dilatations were reviewed. Thirty-one patients were identified who underwent UES dilatation. Median age was 63 years (range 27-81) and 55% of patients were male. Indications included dysphagia (28 patients), globus sensation with evidence of UES dysfunction (2 patients) and obstruction to echocardiography probe with cricopharyngeal (CP) bar (1 patient). There was evidence of concurrent oropharyngeal dysfunction in 16 patients (52%) and a small Zenker’s diverticula (≤ 2 cm) in 7 patients (23%). Dilator size ranged from 15 mm to 20 mm. Of the 31 patients, 11 had dilatation of other esophageal segments concurrently with UES dilatation and 20 had UES dilatation alone. Follow-up was available for 24 patients for a median of 2.5 mo (interquartile range 1-10 mo), of whom 19 reported symptomatic improvement (79%). For patients undergoing UES dilatation alone, follow-up was available for 15 patients, 12 of whom reported improvement (80%). Nineteen patients underwent retrograde dilatation (84% response) while 5 patients had static dilatation (60% response); however, there was no significant difference in symptom improvement between the techniques (P = 0.5). Successful symptom resolution was also not significantly affected by dilator size, oropharyngeal dysfunction, Zenker’s diverticulum, age or gender (P > 0.05). The only complication noted was uvular edema and a shallow ulcer after static dilatation in one patient, which resolved spontaneously and did not require hospital admission.
CONCLUSION UES dilatation with a through-the-scope balloon by either static or retrograde technique is safe and effective for the treatment of dysphagia due to CP dysfunction. To our knowledge, this is the first study evaluating retrograde balloon dilatation of the UES.

Abstract
AIM Cricopharyngeal achalasia (CPA) is a rare clinical condition that is characterized by aspiration, choking, and nasopharyngeal regurgitation. The aim of this study is to introduce the outcomes of dilatation alone in children with CPA. PATIENTS AND METHOD After the evaluation of upper esophageal sphincter with endoscopy, dilatation was performed. All patients underwent videofluoroscopic evaluation and swallowing therapy after the surgical procedure. A retrospective chart review was performed in children with CPA. RESULTS Thirty children who were videofluoroscopically proven to have CPA were included in the study. Their age range was 15days-7years (median 11months). Twenty-one of them were neurologically impaired. Two children were lost to follow-up. Nineteen patients (68%) had a total resolution of CPA and were symptom-free with 1-6 dilatations (median 2). Three of the children (11%) who were severely neurologically impaired had resistant CPA. Three children (11%) treated recently with short follow-up were added to the group. Their VFS evaluations demonstrated improvement, thus we accepted their result as successful. There were two perforations in the series. Three patients died; one 2-month-old (2500g) baby who was accepted from the intensive care unit passed away on postoperative on the 7th day. Two other babies who were unresponsive to dilatation therapy died on follow-up. CONCLUSION Dilatation can be a safe and effective method on children who are correctly diagnosed to have CPA.

Abstract
OBJECTIVE To compare swallowing outcomes following cricopharyngeal (CP) dilation versus surgical myotomy in patients with dysphagia secondary to idiopathic CP bar. METHODS All patients had an idiopathic CP bar without a history of Zenker's diverticulum, head and neck cancer, or systemic neurologic disease treated between 2000 and 2013. The Functional Outcome Swallowing Scale (FOSS) was utilized to assess dysphagia symptoms. RESULTS Twenty-three patients underwent 46 dilations and 20 patients had a myotomy. Nineteen of 23 (83%) patients in the dilation group and all patients in the myotomy group reported improved swallow function. The median difference in pre- versus post-intervention FOSS scores was not statistically significant (p=0.07) between the dilation and myotomy groups with mean reductions of 1.3 and 1.8, respectively. Seventeen of 23 (74%) dilation patients had persistent or recurrent dysphagia with 13 (57%) requiring repeat dilation and 4 (17%) undergoing CP myotomy. The median time to first reintervention in the dilation group was 13.6months. Nineteen of 20 (95%) surgical myotomy patients did not experience recurrent dysphagia. CONCLUSION Both endoscopic CP dilation and myotomy led to similar initial improvement in swallow function for patients with primary idiopathic CP bar; however, dilation is more likely to provide temporary benefit.

Abstract
Objectives: Botulinum toxin injection (BTX) and cricopharyngeal (CP) myotomy are performed in the treatment of CP achalasia (CA). The objective of this study was to examine the effects of BTX on neuromuscular histopathologic findings and to make direct comparisons between specimens of muscle from CA patients who had received BTX to the upper esophageal sphincter and from CA patients who had no previous exposure to BTX. Methods: We performed a retrospective review (2001 to 2005) of CP muscle specimens from all patients who underwent myotomy for CA. Cases of Zenker's diverticulum were excluded. Patient demographics, clinical course, and neuromuscular pathology findings were noted from the chart. Results: Nineteen patients with CA were identified: 10 male and 9 female, with a mean age of 57 years. Eleven had no prior BTX (6 male and 5 female; mean age, 62 years); 8 had previous treatment with BTX (4 male and 4 female; mean age, 51 years). Eight of the 11 BTX-naive patients revealed predominantly myopathic changes on histology. Those with previous BTX tended to be younger; 6 of the 8 had a clinical benefit from their BTX and ultimately went on to myotomy. The CP muscle specimens featured both mixed and neurogenic pathologic changes in 5 of the 8 patients with BTX. Although these findings suggest some impact of BTX on the CP muscle, the difference between the groups was not statistically significant (p < 20, x2 test). Conclusions: Treatment with BTX may have some clinical and histopathologic impact on the upper esophageal sphincter of patients with CA. Although neuropathic changes were noted in the CP muscle of previously injected patients at the time of their CP myotomy, the neuromuscular pathologic findings overall were not significantly different from those of BTX-naive patients.

Abstract
OBJECTIVE A systematic review was performed to evaluate the safety and efficacy of different therapeutic interventions available for the management of isolated cricopharyngeal dysfunction. METHODS Studies were identified using the following databases: Ovid (Medline, Embase), the Cochrane Library, PubMed and Google Scholar. An initial search identified 339 articles. All titles and abstracts were reviewed. Fifty-six relevant articles were inspected in more detail; of these, 47 were included in the qualitative analysis. RESULTS No relevant randomised trials were found. A range of case series were used to perform a qualitative analysis. Botulinum toxin A injection and cricopharyngeal dilatation were associated with a higher risk of recurrence, but appear to be more suitable in elderly and co-morbid patients. In those patients requiring formal myotomy, endoscopic approaches appear to be as effective but less morbid when compared with classical open surgery. CONCLUSION There is good evidence for the safety and efficacy of the different therapeutic options for isolated cricopharyngeal dysfunction. However, further studies are required to compare the efficacy of the various treatment modalities.

Abstract
OBJECTIVES Cricopharyngeal dysfunction may lead to severe dysphagia and aspiration. The objective of this systematic review was to evaluate the existing studies on the effectiveness of myotomy, dilatation, and botulinum toxin (BoT) injection in the management of cricopharyngeal dysphagia. METHODS PubMed and Web of Science databases were searched to identify eligible studies by using the terms "cricopharyngeal dysfunction," "cricopharyngeal myotomy," "cricopharyngeal botox," "cricopharyngeal dilation," and their combinations from 1990 to 2013. This was supplemented by hand-searching relevant articles. Eligible articles were independently assessed for quality by two authors. Statistical analysis was performed. RESULTS The database search revealed 567 articles. Thirty-two articles met eligibility criteria and were further evaluated. The reported success rates of BoT injections was between 43% and 100% (mean = 76%), dilation 58% and 100% (mean = 81%), and myotomy 25% and 100% (mean = 75%). In logistic regression analysis of the patient-weighted averages, the 78% success rate with myotomy was significantly higher than the 69% success rate with BoT injections (P = .042), whereas the intermediate success rate of 73% with dilation was not significantly different from that of either myotomy (P = .37) or BoT (P = .42). There was a statistically significant difference between endoscopic and open myotomy success rates (P = .0025). Endoscopic myotomy had a higher success rate, with a 2.2 odds ratio. CONCLUSIONS The success rate of myotomy is significantly higher than the success rate of BoT injections in cricopharyngeal dysfunction. Moreover, endoscopic myotomy was found to have a higher success rate compared to open myotomy.

Abstract
Cough and swallow are highly coordinated reflex behaviors whose common purpose is to protect the airway. The pharynx is the common tube for air and food/liquid movement from the mouth into the thorax, has been largely overlooked, and is potentially seen as just a passive space. The thyropharyngeus muscle responds to cough inducing stimuli to prepare a transient holding area for material that has been removed from the subglottic airway. The cricopharyngeus muscle participates with the larynx to ensure regulation of pressure when a bolus/air is moving from the upper airway through to the thorax (i.e., inspiration or swallow) or the reverse (i.e., expiration reflex or vomiting). These vital mechanisms have not been evaluated in clinical conditions but could be impaired in many neurodegenerative diseases, leading to aspiration pneumonia. These newly described airway protective mechanisms need further study, especially in healthy and pathologic human populations.

Abstract
The primary aim of this study was to investigate the outcomes of two different modes (active and passive) of balloon dilatation therapy on cricopharyngeal dysfunction (CPD). Thirty-eight CPD patients with neurological disorders were recruited between 2006 and 2010. Twenty-one of them received active balloon dilatation therapy, and the remaining 17 received passive dilatation therapy for an average of 4 weeks. The patients' swallowing function before and after the intervention was evaluated using the Functional Oral Intake Scale (FOIS) and the upper esophageal sphincter (UES) opening was studied with the videofluoroscopic swallow study. Both modes of balloon dilatation therapy yielded improvements in the FOIS (active group: z = -3.767, p < 0.001; passive group: z = -3.472, p < 0.001) and the UES opening (both groups: p < 0.01). Active dilatation showed a significantly better FOIS result (p = 0.028) than passive dilatation for CPD. Both active and passive balloon dilatation benefits patients with neurological disorders but active balloon dilatation is better.

Abstract
Primary cricopharyngeal dysfunction (PCD) is a rare idiopathic disorder of the upper esophageal sphincter (UES), characterized by oropharyngeal dysphagia, frequent aspiration, and narrowing at the level of the UES. Cricopharyngeal myotomy (CPM) has been used to treat oropharyngeal dysphagia of different causes including anatomic, neuromuscular, iatrogenic, inflammatory, neoplastic, and idiopathic; however, the indications for CPM and predictors of its outcome are not clearly defined. We report a case of PCD with hypertonic UES caused by a structural abnormality localized in the cricopharyngeus muscle, visualized as a cricopharyngeal bar, which we treated successfully by CPM, achieving long-term relief.

Abstract
CP bar is an uncommon but important cause of dysphagia in elderly people. A CP bar is often undetected during upper endoscopy and might be missed with barium radiography if adequate attention is not focused on the hypopharynx. In suspected cases, evaluation for alternative etiologies of dysphagia is important because the CP bar might be an incidental finding. Secondary causes of CP dysfunction resulting from underlying primary myopathic or neuropathic disorders should be considered before therapy. The effectiveness of dilation and surgical myotomy in alleviating dysphagia associated with CP bars has been reported in small series.

Abstract
BACKGROUND & AIMS Pharyngeal manometry and impedance provide information on swallow function. We developed a new analysis approach for assessment of aspiration risk. METHODS We studied 20 patients (30-95 years old) with suspected aspiration who were referred for videofluoroscopy, along with controls (ages 24-47 years). The pharyngeal phase of liquid bolus swallowing was recorded with manometry and impedance. Data from the first swallow of a bolus and subsequent clearing swallows were analyzed. We scored fluoroscopic evidence of aspiration and investigated a range of computationally derived functional variables. Of these, 4 stood out as having high diagnostic value: peak pressure (PeakP), pressure at nadir impedance (PNadImp), time from nadir impedance to peak pressure (TNadImp-PeakP), and the interval of impedance drop in the distal pharynx (flow interval). RESULTS During 54 liquid, first swallows and 40 clearing swallows, aspiration was observed in 35 (13 patients). Compared to those of controls, patient swallows were characterized by a lower PeakP, higher PNadImp, longer flow interval, and shorter TNadImp-PeakP. A Swallow Risk Index (SRI), designed to identify dysfunctions associated with aspiration, was developed from iterative evaluations of variables. The average first swallow SRI correlated with the average aspiration score (r = 0.846, P < .00001 for Spearman Rank Correlation). An average SRI of 15, when used as a cutoff, predicted aspiration during fluoroscopy for this cohort (κ = 1.0). CONCLUSIONS Pressure-flow variables derived from automated analysis of combined manometric/impedance measurements provide valuable diagnostic information. When combined into an SRI, these measurements are a robust predictor of aspiration.

Abstract
OBJECTIVES Carbon dioxide laser-assisted endoscopic cricopharyngeal myotomy (ECPM) has emerged as a viable therapy for dysphagia. The risks of the procedure include pharyngoesophageal perforation and mediastinitis, which may discourage adoption of this technique. To address these complications, we examined outcomes of ECPM with primary mucosal closure. METHODS A case series of 7 patients who underwent ECPM between 2006 and 2008 were reviewed for length of operation, length of hospitalization, postoperative complications, and outcomes by use of the M. D. Anderson Dysphagia Index (MDADI) and the Functional Outcome Swallowing Scale (FOSS). The results were compared to those of a control group of 7 patients treated during the same period via open cricopharyngeal myotomy. RESULTS All patients who had ECPM were treated successfully without complications. The operative times averaged 128 minutes. The hospitalization averaged 2.1 days. Statistically significant improvements in swallowing were seen (MDADI score from 51.3 to 77.7, p < 0.0006; FOSS score from 3.7 to 1.3, p < 0.0005), and were similar to those in the patients who had the open procedure (FOSS score from 3.0 to 1.0, p <0.006). Trends toward decreased blood loss, a shorter hospital stay, and a lower complication rate were observed in the patients who had ECPM. CONCLUSIONS ECPM is beneficial as a primary treatment for cricopharyngeal dysfunction. Closure of the mucosal defect may help reduce the incidence of postoperative cervical emphysema and mediastinitis, and does not appear to compromise functional outcome.

Abstract
OBJECTIVES/HYPOTHESIS Cricopharyngeus muscle dysfunction (CPD) ranges from asymptomatic cricopharyngeal bar (CPB) to Zenker's diverticulum. Previous work suggests that CPD can result in dilation and weakening of the pharynx above the obstruction. The purpose of this investigation was to evaluate the ability of surgery on the cricopharyngeus muscle to improve pharyngeal area and strength. STUDY DESIGN Retrospective case study. METHODS Videofluoroscopic swallowing studies of all persons with CPD who underwent cricopharyngeus (CP) intervention followed by routine postoperative fluoroscopic study, between October 1, 1999 and January 1, 2010 were reviewed. Objective measures of pharyngeal area and constriction were obtained from pretreatment and post-treatment studies. Paired t tests and repeated measures analysis of variance were employed to compare results. RESULTS Fifty-four patients were included. Pharyngeal constriction and pharyngoesophageal segment (PES) opening improved significantly after intervention (P < .05).Pharyngeal dilation was unchanged (P > .05). PES opening improved more with CP myotomy than with dilation and botulinum toxin. CONCLUSIONS Relief of CP obstruction by surgery or dilation improves pharyngeal constriction and PES opening. Dilation of the pharynx possibly related to prolonged outlet obstruction does not improve. CP myotomy appears more effective than dilation or botulinum toxin in relieving obstruction.

Abstract
OBJECTIVES/HYPOTHESIS Prolonged obstruction at the level of the lower esophageal sphincter is associated with a dilated, poorly contractile esophagus. The association between prolonged obstruction at the level of the upper esophageal sphincter (UES) and dilation and diminished contractility of the pharynx is uncertain. The purpose of this investigation was to evaluate the association between prolonged obstruction at the level of the UES and dilation and diminished contractility of the pharynx. STUDY DESIGN Case-control study. METHODS The fluoroscopic swallow studies of all persons with cricopharyngeus muscle dysfunction (CPD) diagnosed between January 1, 2006 and December 31, 2008 were retrospectively reviewed from a clinical database. Three categories of CPD were defined: nonobstructing cricopharyngeal bars (CPBs), obstructing CPBs, and Zenker diverticulum (ZD). The primary outcome measure was the pharyngeal constriction ratio (PCR), a surrogate measure of pharyngeal strength on fluoroscopy. Secondary outcome measures included pharyngeal area in the lateral fluoroscopic view and UES opening. The outcome measures were compared between groups and to a cohort of nondysphagic age- and gender-matched controls with the analysis of variance. RESULTS A total of 100 fluoroscopic swallow studies were evaluated. The mean age (+ or -standard deviation) of the cohort was 70 years (+ or -10 years). Thirty-six percent were female. The mean PCR progressively increased, indicating diminishing pharyngeal strength, from the normal (0.08), to the nonobstructing CPB (0.13), to the obstructing CPB (0.22), to the ZD group (0.28) (P < .001 with trend for linearity). There was a linear increase in pharyngeal area from the normal (8.75 cm(2)) to the nonobstructing CPB (10.00 cm(2)), to the obstructing CPB (10.46 cm(2)), to the ZD group (11.82 cm(2)) (P < .01 with trend for linearity). CONCLUSIONS The data suggest that there is an association between cricopharyngeus muscle dysfunction and progressive dilation and weakness of the pharynx. Laryngoscope, 2010.

Abstract
The symptom of cough may result from a multitude of etiologies involving different parts of the aerodigestive tract. This article focuses on the association of cough and swallowing dysfunction in the sense that cough may be an indicator of swallow dysfunction and in the importance of cough in preventing aspiration and aspiration-related disorders. Whereas these associations have been known for a long time, research is starting to connect the dots, allowing targeting of strategies aimed at diagnosing and preventing illness in certain dysphagic patients.

Abstract
OBJECTIVES/HYPOTHESIS Transoral treatment of cricopharyngeal bar and small Zenker's diverticulum remains a challenge. We propose a new transoral approach for transoral cricopharyngeal myotomy (TOCPM) for patients with cricopharyngeal spasm and pharyngeal bar, and for transoral resection of diverticula (TORD) with cricopharyngeal myotomy in the patient with small (<3 cm) Zenker's diverticulum. METHODS A retrospective review was conducted of 45 patients with cricopharyngeal spasm (21) and Zenker's diverticulum (24), where 14 patients were considered suitable for TORD and TOCPM. TOCPM used the Weerda laryngoscope (Karl Storz, Tuttlingen, Germany) to expose the cricopharyngeal bar using a microscope; the mucosa is cut and then the muscle is transected using monopolar cautery. A 0 degrees endoscope is inserted through the incision to ensure complete myotomy. Incision closure is by interrupted 4-0 Vicryl sutures (Ethicon Inc., Somerville, NJ) and fibrin glue. For the TORD procedure, the diverticular sac is everted and then resected using scissors. Through the sac opening, the TOCPM is completed. The sac opening is then closed as described in TOCPM. The patients are kept without food for 24 hours, followed by feeding and discharge. Modified barium swallow (MBS) evaluated functional results. RESULTS Fourteen patients underwent TOCPM (eight), and TOCPM+TORD (six). There was one case of TOCPM that was aborted due to excessive bleeding, which prevented full myotomy. The rest did well. All were discharged the next day. Two poor results from the TOCPM and TOCPM+TORD group were due to poor esophageal motility. The remainder of patients had resolution of dysphagia and normalized MBS. No patient developed stricture or complications. CONCLUSIONS Short segment Zenker's diverticulum and cricopharyngeal bar can now be addressed completely with a transoral approach. Because there is complete closure of the mucosal incision, prolonged hospitalization can be avoided.

Abstract
Although the aging process per se can produce measurable changes in the normal oropharyngeal swallow, these changes alone are rarely sufficient to cause clinically apparent dysphagia. The causes of oropharyngeal dysphagia in the elderly are predominantly neuromyogenic, with the most common cause being stroke. The evaluation of oropharyngeal dysphagia in the elderly involves early exclusion of structural abnormalities, detection of aspiration by videofluoroscopy which might dictate early introduction of nonoral feeding, and exclusion of underlying systemic and neuromyogenic causes that have specific therapies in their own right. Such conditions include Parkinson disease, myositis, myasthenia, and thyrotoxicosis. Management is best delivered by a multidisciplinary team involving physician, speech pathologist, nutritionist and, at times, a surgeon.

Abstract
OBJECTIVES Over the past 10 years, endoscopic cricopharyngeal myotomy laser surgery has been proposed as an alternative to transcervical cricopharyngeal myotomy. We will describe the technique and review the literature so that it may gain credence as a viable option for the treatment of cricopharyngeal achalasia. METHODS A literature review of endoscopic and transcervical cricopharyngeal myotomy will be performed. The technical aspects of endoscopic cricopharyngeal myotomy will be presented and accompanied by intraoperative photographs, illustrations, and an online video demonstration. RESULTS Endoscopic cricopharyngeal myotomy is a well-tolerated procedure with low morbidity and good outcomes. It can be performed by surgeons who are comfortable with transoral laryngopharyngeal laser surgery. CONCLUSIONS Endoscopic cricopharyngeal myotomy is a viable alternative to classic transcervical cricopharyngeal myotomy with equivalent outcomes and comparable if not less morbidity.

Abstract
This study aimed to use a novel high-resolution manometry (HRM) system to establish normative values for deglutitive upper esophageal sphincter (UES) relaxation. Seventy-five asymptomatic controls were studied. A solid-state HRM assembly with 36 circumferential sensors spaced 1 cm apart was positioned to record from the hypopharynx to the stomach. Subjects performed ten 5-ml water swallows and one each of 1-, 10-, and 20-ml volume swallows. Pressure profiles across the UES were analyzed using customized computational algorithms that measured 1) the relaxation interval (RI), 2) the median intrabolus pressure (mIBP) during the RI, and 3) the deglutitive sphincter resistance (DSR) defined as mIBP/RI. The automated analysis succeeded in confirming bolus volume modulation of both the RI and the mIBP with the mean RI ranging from 0.32 to 0.50 s and mIBP ranging from 5.93 to 13.80 mmHg for 1- and 20-ml swallows, respectively. DSR was relatively independent of bolus volume. Peak pharyngeal contraction during the return to the resting state postswallow was almost 300 mmHg, again independent of bolus volume. We performed a detailed analysis of deglutitive UES relaxation with a novel HRM system and customized software. The enhanced spatial resolution of HRM allows for the accurate, automated assessment of UES relaxation and intrabolus pressure characteristics, in both cases confirming the volume-dependent effects and absolute values of these parameters previously demonstrated by detailed analysis of concurrent manometry/fluoroscopy data. Normative values were established to aid in future clinical and investigative studies.
