About our founder- Dr. Guoyi Chen

Born in Luzhou, China, Dr. Guoyi Chen has dedicated his life to the “Mastering of Great Skills to Alleviate the Suffering of Patients.” Dr. Guoyi Chen is from a family with a long history of practicing Traditional Chinese medicine. The history of the Chen family is very strong as they’re known for creating effective traditional Chinese medicine formulas. For instance, Dr. Guoyi Chen cured his lymphoma by creating his own formula. During Dr. Guoyi Chen’s long journey of medical practice, he found that some benign anorectal diseases had a toll on people’s lives and severely impacted their quality of life. Although these ailments are not life-threatening, they can be extremely bothersome since they affect bowel movement, self-confidence, and basic daily tasks. Also, Dr. Guoyi Chen noticed that most hemorrhoid treatments are challenging and with questionable effectiveness.

Because of these obstacles, Dr. Guoyi Chen decided to dedicate his medical practice to focus on benign and common anorectal diseases (e.g., hemorrhoids, anal skin tags, chronic anal fissures, anal abscesses, anal fistulas, Pruritus Ani). Dr. Guoyi Chen used his rich knowledge of Traditional Chinese medicine and formulated Ba Zhi San anorectal creams. Moreover, he developed unique, safe, and effective anorectal minor surgery techniques. The technique blended with the Ba Zhi San ointment avoids all the complications that we mentioned above. Guoyi Proctology Therapy was formed. The treatment goal is to minimize the external trauma and maximize the natural medicine to remove the defective tissue and the body’s own healing capacities, also ensure that patients recover swiftly after the procedure and with minimal sequala.

In 1979, Dr. Guoyi Chen moved to Xi’an and established the first Piles and Fistula hospital in the region. Since then, this technique has successfully treated thousands of patients who suffer from anorectal diseases such as hemorrhoids, anal fissures, abscesses, and anal fistula. The long experience of Dr. Guoyi Chen in the field of proctology, Chen family introduces unique approach to treating anorectal diseases to world-wide.

Dr. Guoyi Chen has established himself as a preeminent expert in the field, having served as Director of Piles and Fistula at Beijing Chinese Medicine University, as well as Chief Physician of China Oriental Hospital. His techniques and treatments have been introduced throughout the world, including at Columbia University in New York. Dr. Chen has been invited to give lectures in Hong Kong, Singapore, Spain, Canada, and the United States on the topic of promoting Traditional Chinese Medicine worldwide.

If we had to summarize this technique in a few points, here’s what we have to say:

Anorectal Treatment- Guoyi Proctology Therapy

Guoyi Proctology therapy — a unique naturopathic modality that combines both minor-surgical and non-surgical procedures with BZS (Ba Zhi San) series ointment, aiming to resolve anal diseases at their root.

The main benefits of Guoyi Proctology Therapy are:

Quickly stop pain and bleeding – Rapid symptomatic relief.
Treats numerous anorectal benign diseases with minor surgery – Big problem? Simple solution.
Fast healing – Short downtime.
Manageable pain – No bedtime or hospitalization needed.
Individualized the post-treatment Ba Zhi San ointments care – avoids complications (no scarring, anal stenosis, or fecal incontinence).
Eliminates the need for multiple treatment sessions – All-In-One solution.

Minor Surgical Treatment

Minor surgical techniques use local anesthesia to perform the incision and excision in a pain-free manner. After that, the full therapeutic effects of the Ba Zhi San ointment are leveraged to ensure the sphincters remain intact. This non-invasive procedure is reserved for addressing specific symptoms. The procedure spans 10 to 40 minutes and is carried out in an outpatient setting.

It is suitable in the following situations:

A replacement method for patients with 3rd and 4th-grade hemorrhoids who don’t want to undergo major surgery. For example, hemorrhoids prolapse for a long time that cannot be pushed back manually.
Anal skin tags
Chronic Anal Fissures.
Painful external hemorrhoids
Thrombosed hemorrhoids.
Perianal abscess
Anal fistula

Some basics about minor surgical treatment include:

No fasting is required
No bedtime or hospitalization is required
Local anesthesia (No risks of general anesthesia)
All-in-one solution that resolves complex anorectal disorders
Minimal pain compared to hemorrhoidectomy (i.e., the surgical removal of hemorrhoids)
Possibility of same-day procedure
Used the benefits of Ba Zhi San ointment

Non-Surgical anorectal Treatment

Our exclusive BZS (Ba Zhi San) ointments medicine can detoxify and relieve anal bleeding, perianal pain, and itching. The pharmacological effect dissolves decay and promotes muscle growth, drying of hemorrhoid roots, and wound healing. This helps to resolve hemorrhoids.

Non-Surgical Anorectal Treatment is suitable for:

Internal hemorrhoids grades 1 and 2
People who cannot undergo surgery (e.g., age above 80 years old, concurrent medical conditions)
Individuals who seek a personalized approach that uses modern and natural medicine
Those who need to manage pain and reduce inflammation before making further treatment decisions.

The benefits of this treatment include:

Post-treatment phase of anorectal disease

Since we understand the importance of post-treatment care, we take a very unique approach to this phase. During the hemorrhoid post-treatment, we focus on stage one, which is a mandatory stage for daily care. This is important since our technique removes the hemorrhoids partially and progressively. Differently put, we do not remove all the hemorrhoids at once.

Stage one of post-treatment care involves the application of the Ba Zhi San Ointment to dry off the hemorrhoids. For this reason, patients can have normal bowel movements from the second day of the surgery. The minimal trauma and application of the Ba Zhi San Ointment eliminates the need for patients to be admitted to the clinic. They can simply drive to the clinic to receive post-treatment care in most of the cases.

The main features of post-treatment are:

Ba Zhi San anorectal Ointment Focus – A specialized treatment formulated to address the specific needs of anorectal disorders. Its therapeutic properties aid in healing and recovery.
Professional Application – Each treatment session involves the application of the B-Line ointment by a skilled doctor's assistant under the direct supervision of our senior doctor, which ensures the highest standard of care.

BZS (Ba Zhi San) Series Ointment

General Function

BZS (Ba Zhi San) ointments are cream-based medicines infused with a unique botanical formula that relieves pain, stops bleeding, reduces inflammation and swelling, combat infections, detoxifies the nearby tissues, eliminates slough, and promotes wound healing granulation. Each ointment serves a specific function at a specific location in the anal canal. In other words, your doctor will choose the best BZS (Ba Zhi San) ointments for you based on your symptoms, the location of the lesions, and previous responses to other types.

The BZS (Ba Zhi San) ointments restore proper muscle function and connective tissue, which resolves anal conditions. The pharmacological mechanism of these ointments includes the blockage of venous blood supply and the elimination of moisture from the body.

Personalized Therapy

The application of BZS (Ba Zhi San) ointments achieves an ideal treatment effect that addresses both symptoms and underlying causes, which reduces the treatment duration and prevents recurrence. Tailored formulations of BZS (Ba Zhi San) ointments are created based on diagnosis and symptoms, ensuring effective treatment for specific conditions. Personalized dosages maximize optimal results for each patient.
