Design and implementation of botulinum toxin on cricopharyngeal dysfunction guided by a combination of catheter balloon, ultrasound, and electromyography (BECURE) in patients with stroke: study protocol for a randomized, double-blinded, placebo-controlled trial

Acupuncture combined with balloon dilation for post-stroke cricopharyngeal achalasia: A meta-analysis of randomized controlled trials

Background

The purpose of this study was to systematically evaluate the effectiveness of acupuncture combined with balloon dilatation in patients with post-stroke cricopharyngeal achalasia (CPA) according to the effective rate, videofluoroscopy swallowing study (VFSS) score and standardized swallowing function assessment scale (SSA) score through Meta-analysis.

Methods

English and Chinese language literature published before July 24,2022 were searched in ten electronic databases. The identified articles were screened, data were extracted, and the methodological quality of the included trials was assessed. Using RevMan 5.4.1 software to perform Meta-analysis.

Results

10 studies with 517 patients with post-stroke CPA were included. Meta-analysis showed that the effective rate of the experience group was higher than that of the control group [OR = 0.62; 95% CI (2.32, 13.05); I 2 = 0%; p = 0.0001]. Compared to the control group, the SSA score was lower in the experience group [MD = -4.22; 95% CI (-4.57, -3.87); I 2 = 42%; p < 0.00001]. In terms of VFSS scores, the experience group showed greater efficacy differences than control group [MD = 1.53; 95% CI (1.32, 1.75); I 2 = 0%; p < 0.00001]. The subgroup analysis of VFSS score based on the average course of disease (<1 month vs. ≥1 month) showed no significant difference. The subgroup analysis based on average age (>60 years vs. ≤60 years) showed the VFSS score of the experience group was significantly higher than that of the control group, and the effect may be better in the subgroup older than 60 years. The subgroup analysis based on the treatment course (>30 days vs. ≤30 days) showed the VFSS score of the experience group was significantly higher than that of the control group, and the effect may be better in the subgroup the treatment course>30 days.

Conclusion

Acupuncture combined with balloon dilatation may be an effective method for treating post-stroke CPA. Compared with balloon dilatation, acupuncture combined with balloon can significantly improve the swallowing function of patients, and it is also effective for patients of different courses, ages, and treatment course, while patients over 60 years old and the treatment course over 30 days may have better clinical outcomes.

Case report: A case of novel treatment for retrograde cricopharyngeal dysfunction

Retrograde cricopharyngeal dysfunction (R-CPD) is a recently described disorder characterized by an inability to belch, excessive flatulence, unpleasant gurgling noises, and discomfort in the lower neck, chest, and abdomen. Herein, we describe a case of R-CPD in a 19-year-old man. The patient suffered from flatulence and was unable to belch since birth; auxiliary examination of his digestive system was normal. He was diagnosed with R-CPD based on clinical manifestations and laboratory results. He received an injection of botulinum toxin to the cricopharyngeal muscle under ultrasound, catheter balloon, and electromyographic guidance. His symptoms completely resolved 1 week after the injection.

Botulinum toxin A injection using ultrasound combined with balloon guidance for the treatment of cricopharyngeal dysphagia: analysis of 21 cases

BACKGROUND

As an upper oesophageal sphincter (UES) dysfunction disorder, cricopharyngeal achalasia (CPA) is a common cause of dysphagia and is associated with an increased risk of pulmonary complications. The aim of this study was to investigate the effectiveness and safety of BTX-A injection using ultrasound combined with balloon guidance for the treatment of CPA caused by stroke.

METHODS

A total of 21 patients diagnosed with CPA were treated with BTX-A injection into the cricopharyngeal muscle using ultrasound combined with balloon guidance. Primary outcome measures, including the functional oral intake scale (FOIS), videofluoroscopic dysphagia scale (VDS) and penetration aspiration scale (PAS), which are quantitative measures for a video fluoroscopic swallowing study (VFSS), and scores of the self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were assessed from baseline to 12 weeks after treatment. Repeated measures analysis of variance was used to compare the scores between time points.

RESULTS

BTX-A injection led to improved dysphagia symptoms and scores in 19 patients (90.48%). Among them, 5 cases were cured (23.81%), 11 cases showed significant improvement (52.38%), and 3 cases showed improvement (14.29%). Two cases were absolutely ineffective (9.52%). Compared with the scores prior to treatment, the scores on the FOIS, VDS, PAS, SAS and SDS significantly improved beginning at 3 days (p < .05) and lasting for at least 12 weeks after injection.

CONCLUSIONS

Ultrasound with balloon-guided BTX-A injection is probably a relatively safe, easy, and effective technique for the treatment of CPA caused by stroke, with better visualization of the injection procedure. A well-designed controlled trial with a larger sample size is needed for more convincing conclusions.
