Intersphincteric fistula is a type of anal fistula in which a narrow tunnel of granulation tissue is formed with one end opening into the anal canal and the other in the skin near the anus. In the case of an intersphincteric fistula, the fistula begins between the internal and external sphincter muscles. This condition results from an abscess formed when the outlet of anal glands are blocked. It can also recur if there is an accumulation of pus each time the fistula is sealed. Apart from the presence of pus, the patient also experiences pain and swelling in the affected area and fever. Stool can sometimes pass through the fistula, leading to a high possibility of systemic infection.
To completely treat an intersphincteric fistula and prevent its recurrence, the patient needs to undergo surgery called primary fistulotomy in which a probe in inserted into the fistula and the overlying tissue is divided. Such surgery is widely available in Southeast Asian countries such as Singapore, Malaysia, and Thailand. These countries have a large number of Joint Commission International (JCI)-accredited hospitals that are fully equipped with sophisticated surgical equipment and advanced medical facilities; the same ones found in modern hospitals in Western countries. Deeply committed to maintaining the high quality of care they provide, these hospitals give priority to surgeons who have decades of experience, expertise, and training abroad when hiring.
These facilities cater to foreign patients seeking treatment at a much affordable cost. When compared to Western countries like the United States, the majority of medical and surgical services in Southeast Asia are up to 75% cheaper. Aside from affordable costs, patients can also gain access to advanced treatment methods for intersphincteric fistulas. These include the use of stem cells in clinical trials to promote healing and reduce the occurrence of inflammation.
