About this study
Official title: Effectiveness Evaluation of Mixed Gel of Hydrocortisone and Aluminium Phosphate Preventing Endoscopic Submucosal Dissection Postoperative Stenosis for Patients With Early Esophageal Cancer Invading More Than 2/3 Esophageal Perimeter
Endoscopic submucosal dissection as the fastest growing endoscopic treatment technology in the past decade has been widely used in the treatment of early esophageal cancer and gastric cancer without local lymph node metastasis. The main complications of ESD treatment of early esophageal cancer are hemorrhage, perforation, postoperative esophageal stenosis, infection, etc. Postoperative esophageal stenosis is the most common and major complication after ESD treating patients with lesion involving more than 2/3 esophagus cycle. It is very important to prevent esophageal stricture after ESD. Glucocorticoid is gradually concerned by clinical research because it can inhibit local inflammatory response and reduce the formation of connective tissue in order to prevent postoperative stenosis. The specific usages include endoscopic injection of corticosteroids, oral corticosteroids and combination of them. The study shows that the incidence of esophageal stricture after using glucocorticoid can be reduced effectively. Currently, there is no uniform consensus on the use of glucocorticoids, such as specific drugs, dosage, course of treatment, route of administration. In particular, efficacy comparison of different routes of administration is laking. Studies have shown that endoscopic injection triamcinolone acetonide in some patients with intractable esophageal stricture is not very effective, but it can be treated with oral corticosteroids. Aluminium Phosphate Gel is a kind of neutral buffer. The main component aluminum phosphate can form a strong ion buffer system in acidic environment. The structure of its auxiliary components agar and pectin is similar to that of natural mucus. It forms a mucous layer in the esophagus to restore and protect the esophageal mucosa. Therefore, investigators assume the hydrocortisone sodium succinate aluminum phosphate mixed gel can be used for preventing postoperative ESD stenosis of patients with a large area of early esophageal cancer. This study will design a randomized controlled trial to compare the effect of oral hydrocortisone sodium succinate mixed Aluminium Phosphate Gel and local injection of triamcinolone acetonide plus oral prednisone for the prevention of ESD postoperative esophageal stricture in patients with a large area of early esophageal cancer.

The investigators will recruit patients according to admission criteria and exclusion criteria. The patients will be randomly divided into oral hydrocortisone mixed Aluminium Phosphate gel group (experimental group) and local injection of triamcinolone acetonide plus oral prednisone group (control group). The test group begin to take hydrocortisone sodium succinate mixed with Aluminium Phosphate gel after 24 hours and gradually reduse the dose. The control group will get local injection of triamcinolone acetonide in wound during the operation, and begin to take oral prednisone after 24 hours and gradually reduse the dose. The main result is esophageal stenosis rate 3 months after ESD.

The rate of endoscopic balloon dilation and its therapeutic effect.
We will compare the rate of endoscopic balloon dilation and its therapeutic effect of the two groups

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Endoscopic submucosal dissection as the fastest growing endoscopic treatment technology in the past decade has been widely used in the treatment of early esophageal cancer and gastric cancer without local lymph node metastasis. The main complications of ESD treatment of early esophageal cancer are hemorrhage, perforation, postoperative esophageal stenosis, infection, etc. Postoperative esophageal stenosis is the most common and major complication after ESD treating patients with lesion involving more than 2/3 esophagus cycle. It is very important to prevent esophageal stricture after ESD. Glucocorticoid is gradually concerned by clinical research because it can inhibit local inflammatory response and reduce the formation of connective tissue in order to prevent postoperative stenosis. The specific usages include endoscopic injection of corticosteroids, oral corticosteroids and combination of them. The study shows that the incidence of esophageal stricture after using glucocorticoid can be reduced effectively. Currently, there is no uniform consensus on the use of glucocorticoids, such as specific drugs, dosage, course of treatment, route of administration. In particular, efficacy comparison of different routes of administration is laking. Studies have shown that endoscopic injection triamcinolone acetonide in some patients with intractable esophageal stricture is not very effective, but it can be treated with oral corticosteroids. Aluminium Phosphate Gel is a kind of neutral buffer. The main component aluminum phosphate can form a strong ion buffer system in acidic environment. The structure of its auxiliary components agar and pectin is similar to that of natural mucus. It forms a mucous layer in the esophagus to restore and protect the esophageal mucosa. Therefore, investigators assume the hydrocortisone sodium succinate aluminum phosphate mixed gel can be used for preventing postoperative ESD stenosis of patients with a large area of early esophageal cancer. This study will design a randomized controlled trial to compare the effect of oral hydrocortisone sodium succinate mixed Aluminium Phosphate Gel and local injection of triamcinolone acetonide plus oral prednisone for the prevention of ESD postoperative esophageal stricture in patients with a large area of early esophageal cancer.

Questions about this trial
What is this clinical trial studying?
A study testing Hydrocortisone sodium succinate mixed with Aluminium Phosphate gel (route of administration), Triamcinolone Acetonide (route of administration) and Prednisone (route of administration) in people with Esophageal Stenosis Acquired, run by Peking University Third Hospital at 1 site in China.

Who may be eligible to take part?
The sponsor lists 3 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 20 Jan 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Esophageal stenosis rate (time frame: 3 months after ESD). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03165344, which also lists 12 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Jan 2021; AzTrials last refreshed its copy on 7 Nov 2026.
