Reporter: Director Zhai, hello! I heard that the scientific research team you led has a technical achievement that passed the provincial appraisal, reaching the leading domestic level. Can you give a specific introduction to the general public?
Director Zhai (hereinafter referred to as Zhai): The department I lead focuses on anorectal diseases. In the past 3 years, it has conducted in-depth research on hemorrhoids, colorectal cancer, intractable constipation, and ulcerative colitis. Recently, the result of our research group "PPH Treatment of Annular Internal Hemorrhoids" passed the provincial and ministerial appraisal and reached the domestic leading level.
Reporter: What is PPH? Can you introduce to us?
Zhai: When talking about PPH, we must first talk about hemorrhoids. What is hemorrhoids? Many non-professional doctors are very vague about this concept, and have great misunderstandings about the diagnosis and treatment of hemorrhoids. In fact, hemorrhoids are caused by pathological hypertrophy or displacement of the anal cushion. The anal cushion is the normal tissue in the anal canal, which plays an important role in fine control. As a doctor, he should be clear about the nature of hemorrhoids and should not "treat when hemorrhoids are seen"; the curative effect standard of hemorrhoids is symptom relief, not elimination of hemorrhoids; asymptomatic hemorrhoids do not need treatment, and symptomatic hemorrhoids do not need radical treatment; surgical indications should be strictly controlled . Traditional surgery is to remove pathological anal pads, especially for circular internal hemorrhoids, which must be circularly removed. After surgery, there are more or less incontinence or anal closure. Excessive mucosal resection not only affects the function of fine bowel control, but also destroys sensory nerve endings and mucosal sensilla. The PPH that we have developed is to pull the prolapsed hemorrhoid tissue and move it up and fix it, block the blood supply of the hemorrhoid tissue, control the bleeding and gradually shrink the hemorrhoid tissue, without removing the anal cushion, and control the stool after the operation. Function is not impaired. Because of the circumcision of part of the rectal mucosa, the rectal mucosa can be relatively flat, which has obvious effects on the prolapse of the rectal mucosa and the protrusion of the rectum. PPH can be said to be a revolution for hemorrhoid surgery, conceptually correcting the traditional operation of "seeing hemorrhoids and cutting hemorrhoids". It retains the complete structure of the anal cushion, does not affect the control function and eliminates bleeding, prolapse, pain and other symptoms. The operation is relatively simple. The incision is located in the rectal cavity. It is a painless area operation. It is painless and scarless after the operation. The wound does not need to be changed. The hospitalization is only 2-3 days. It is now widely used in developed countries and regions.
Reporter: Director Zhai, how many such operations have you completed in your hands?
Zhai: In the past 3 years, we have carried out PPH to treat nearly 600 cases of hemorrhoids. The effect is very satisfactory and there are almost no complications. More and more patients choose this operation.
Reporter: Is there nothing bad about PPH?
Zhai: Yes, the total price of PPH is 2-3 times that of traditional surgery, which is a bit expensive for ordinary working class. However, it is entirely possible to get more rewards for the 20 days or so saved by not having to change dressing after surgery.
Zhai: It should be said that the scope of professional diagnosis and treatment of our department has far exceeded the traditional anorectal department, which mainly includes: benign and malignant colorectal diseases (such as colon cancer, rectal cancer, colorectal adenomas, polyps, etc.); ordinary anus Diseases (such as hemorrhoids, anal fistulas, anal fissures, perianal abscesses, etc.); inflammatory diseases of the large intestine (such as ulcerative colorectitis, Crohn's disease, radiation enteritis, appendicitis, etc.); low intestinal obstruction caused by various reasons; various types Constipation (such as outlet obstruction constipation, slow transit constipation, mixed constipation); various intestinal fistulas; anorectal, pericolon and sacrococcygeal lesions, and anorectal congenital diseases.
The incidence of colorectal cancer has been on the rise in recent years. Among the top ten cancers in China, it has risen from the fifth and sixth to the third and fourth, and the incidence of cancer in the digestive system is the second. Surgery is an important means to treat rectal cancer. In principle, radical rectal cancer surgery can be divided into diversion surgery to remove the anus and radical surgery to preserve the anus. About 70% to 75% of colorectal cancers occur in the rectum, while only 20% to 30% of diagnosed rectal cancers can be diagnosed and treated early. According to previous methods, most patients still need artificial anus , Which seriously affects the quality of life of patients; even after the diversion of the anus is removed, the local recurrence rate can still reach 20% to 40%. What should be paid attention to is: local recurrence is the main problem affecting the long-term survival rate of patients! The long-term research of domestic and foreign scholars on the recurrence of rectal cancer after surgery shows that the resection of the mesorectum is closely related to the recurrence of rectal cancer after surgery!
Reporter: Director Zhai, I have gained a lot of knowledge after listening to your explanation. How can I contact you when I see a doctor?
Reporter: Thank you, I hope you can benefit the majority of patients!
Zhai: You are welcome, say hello to the majority of anorectal patients for me! Wish him (her) get rid of the trouble of anorectal diseases as soon as possible!
