Clinical Trial Summary

The goal of this clinical trial is to investigate the clinical efficacy of repetitive transcranial magnetic stimulation in the treatment of achalasia in patients diagnosed with achalasia by comprehensive evaluation of clinical symptoms, HREM, and barium meal examination, optimize rTMS treatment parameters, and provide an effective and noninvasive new treatment strategy for achalasia. The main questions it aims to answer are: 1. To investigate the clinical efficacy of individualized treatment of achalasia with optical 3D navigation repetitive transcranial magnetic stimulation. 2. Optimize rTMS parameters to achieve the best clinical treatment. Participants will need to fill out the Eckardt score scale and SF-36 quality of life scale, undergo cranial T1 structural magnetic resonance for functional connectivity analysis, and select the brain region with the strongest positive functional connectivity to the DMV as the rTMS target. All patients were randomly divided into four groups: sham-rTMS group, 5Hz-rTMS group, 10Hz-rTMS group, and 30Hz-rTMS group, and each group received acute and chronic stimulation, respectively. In the acute stimulation stage, patients only need to do rTMS once, and HREM and HRV detection are given before and after rTMS (stimulation for 1s, interval for 4s, 10 pulses per second, receiving a total of 3000 pulses); in the chronic stimulation stage, patients receive 25 minutes of rTMS actual stimulation or sham stimulation each time, lasting for 20 times, which is completed within 30 days, and the actual stimulation parameters are the same as those of acute stimulation, and the sham stimulation coil is consistent with the appearance and sound of proper stimulation, but there is no substantial stimulation. High-definition esophageal manometry, timed barium meal, heart rate coefficient of variation, and serum neurotransmitters were performed before and after chronic stimulation. Finally, a weekly telephone follow-up was performed for 12 weeks, including Eckardt score and SF-36 quality of life scale.


Description:

Study hypothesis: By analyzing the strongest resting-state functional connectivity between DMV and right precentral gyrus, left postcentral gyrus, and left brain leads in achalasia patients, individualized rTMS treatment with optical 3D navigation was applied to relax LES and relieve the clinical symptoms of dysphagia. Statistical methods: SPSS 25.0 software was used to process the data, symptom score, manometry parameters, serum transmitters and other quantitative indicators. If they met the normal distribution, they were expressed as Mean ± SD. The t-test was performed for the comparison between the two groups; if they did not obey the normal distribution, the median (quartile) was used for statistical description. The rank sum test was used for the comparison between the two groups. Enumeration data were described using number of cases (percentage), and X2 test, corrected X2 test, or Fisher exact test were performed for comparison between the 2 groups.

Outcome

Type Measure Description Time frame Safety issue
Primary Eckardt score The Eckardt scoring system is used to assess the severity of symptoms, with 0 to 1 in grade 0, 2 to 3 in grade I., 4 to 6 in grade II., and > 6 in grade III. The more severe the symptoms, the higher the score, and can also be used for efficacy assessment. Measured immediately after intervention.
Primary Real-time esophageal barium meal examination The severity of the patient 's condition and the therapeutic effect were evaluated by defining the height and maximum width of the residual barium area. Measured immediately after intervention.
Primary High-resolution esophageal manometry(HREM) HREM is the gold standard for the diagnosis of achalasia of cardia (AC), which can assess the relaxation ability of the lower esophageal sphincter (LES) and the contraction ability of the esophageal body. HREM dynamically collects the mean pressure data of multiple parts of the whole esophagus in real time, and converts the linear manometry pattern into color pressure topography. The basic manometry parameters include integrated relaxation pressure (IRP) and lower esophageal sphincter pressure (LESP), which can more truly reflect the relaxation function of the gastroesophageal junction (EGJ) and are the key indicators for the diagnosis of AC. Measured immediately after intervention.
Secondary Heart rate variability assessment Dynamic electrocardiogram recording analysis of sympathetic vagal activity. Measured immediately after intervention.
Secondary Neurotransmitter detection analysis Serum ACh, NO and VIP Measured immediately after intervention.
