Abstract: Background　Haemorrhoids are one of the common diseases in anus and intestinal department, and injection therapy is used as a recommended treatment, but there is a lack of national data on the depth of application and standardised application of injection therapy, which makes it necessary to carry out this research study. Objective　To explore the depth and breadth of current haemorrhoidal injection treatment in China, its standardised application, effectiveness and safety, and the reasons for its failure to be carried out.Methods　An online questionnaire was issued to the members of the Professional Committee of Anal and Intestinal Diseases of the Chinese Association of Pharmaceutical Education from October 2022 to July 2023, and the content of the questionnaire was designed by ourselves, with a total of 37 questions, which included demographic information, methods of treating haemorrhoids, the application of injectable treatments, and complications, etc., and the data were statistically analysed by applying SPSS.Results　A total of 335 questionnaires were recovered, 312 valid questionnaires (recovery rate 93.1%), more than 60% of doctors have implemented more than 500 cases of injection treatment, and there is no significant difference between hospitals at all levels. Injection treatment is more preferred for Ⅰ ~ Ⅱ degree of internal haemorrhoids, with a low recurrence rate of injection treatment and fewer side-effects, but there are still some complications.Conclusion　Haemorrhoidal injection therapy is widely used in China, with low recurrence rates, few side effects, making it suitable for promotion at all levels of hospitals, although some doctors are unaware of its indications and need to be trained in relevant aspects to ensure standardisation of treatment; in addition, most doctors use haemorrhoidal injections in conjunction with other surgical procedures, and there is a need to continue to promote the use of haemorrhoidal injections on their own.
