The use of sclerotherapy with polidocanol foam in the treatment of second-degree haemorrhoidal disease – a video vignette

Haemorrhoidal disease (HD) is one of the most common
anorectal conditions, with a prevalence ranging
between 4% and 36% of the population.
Depending on its severity, HD can be effectively
treated with medical and office-based procedures such
as rubber-band ligation or sclerotherapy or various
surgical approaches. Sclerotherapy has been
described for treating Grade I–III HD. The injection
of a sclerosing agent such as polidocanol provokes
an inflammatory reaction with subsequent necrosis,
fibrosis and fixation of the haemorrhoidal tissue. The
success rate of sclerotherapy varies depending on the
definition of success, the type of sclerosing agent
injected and the degree of HD.
