I-PDT: a ray of hope for fistulas, hidradenitis and basal cell carcinomas

The I-PDT photodynamic therapy with INTERmedic Multidiode™ 630 PDT laser offers a solution to people suffering from hidradenitis suppurativa and basal cell carcinoma, among other pathologies.

The photodynamic laser therapy I-PDT is a minimally invasive laser solution that solves these pathologies in a few sessions, without surgery, without hospitalization and without sick leave. Effective, comfortable and with outstanding aesthetic results, this new treatment technique significantly improves the quality of life of patients and offers them hope for a cure, as evidenced by the excellent performance results seen so far in different clinical studies.  In this article we look at what these three pathologies consist of, and what advantages treatment with I-PDT photodynamic laser therapy offers compared to the conventional approach with traditional treatment techniques, such as oral medication or surgery. 

Basal cell carcinoma or basalioma

What is it? It is a type of skin cancer most frequent among patients over the age of 50. It usually appears on the areas of the body most exposed to solar radiation (hands, face, neck and neckline). It can appear in the form of a nodule or ulcer, which can lead to bleeding. The diagnosis of basal cell carcinoma is confirmed by biopsy. Early detection and the slow growth of these types of tumours mean that in most cases they can be treated effectively.

Who treats it? Dermatologist and plastic surgeon.
Conventional approach. Depending on the size of the tumour and its location, its complete removal is performed by conventional surgery or Mohs surgery (removing the tumour layer by layer after verification). In small lesions, cryotherapy and topical immunomodulator drugs are used.

I-PDT photodynamic laser therapy. Photodynamic therapy conveniently and effectively eliminates large, superficial and deep tumours, without resorting to surgery, leaving no scars.

Hidradenitis suppurativa

What is it? It is a chronic, inflammatory autoimmune disease characterized by the appearance of nodules, boils and fistulas in the apocrine glands in the armpits, groin, buttocks and genital area. It affects nearly half a million people in Spain, but most of the population does not know about. Hidradenitis suppurativa is difficult to diagnose, treat and, as of yet, there is no definitive solution.

Who treats it? The dermatologist.

Conventional approach. It includes oral medication (retinoids, antibiotics and immunosuppressants with unwanted side effects), corticosteroid injections and biological therapy, with slow and costly results.

I-PDT photodynamic laser therapy. It is a minimally invasive therapy, which is fast, convenient and affordable for both doctor and patient. It involves injecting a photosensitizer in the area of ​​the lesion and irradiating it with a 630nm laser from the inside.  Studies performed in the Hospital of León find that there is a clear improvement in hidradenitis suppurativa in patients treated with a single session of I-PDT.

Anal/colorectal fistulas

What is it? Anal or colorectal fistula is a channel-shaped lesion in the anal area that contacts the skin, vagina or bladder. It is caused by injury, infection or inflammation, symptoms are severe pain, itching, burning, bleeding and discharge of stool. Sometimes an abscess can appear.

Who treats it? The General Surgeon and the Proctologist.

Conventional approach. The traditional treatment involves surgery, and the risks inherent to any surgical procedure (anaesthesia, infection), as well as the possibility of the occurrence of side effects such as stool incontinence.

I-PDT photodynamic laser therapy. The purpose of photodynamic laser therapy for anal fistula is to encourage the healing process of that channel, removing the epithelial tissue and facilitating its closure. It induces selective necrosis without damaging adjacent tissues.
