TST (Tissue-selecting Therapystapler) minimally invasive surgery, also known as selective hemorrhoid mucosal anastomosis, is hailed as the "safest minimally invasive technology" by the anorectal diagnosis and treatment community. It is a new type of technology developed on the basis of PPH. It is mainly suitable for patients with stage III and IV hemorrhoids with non-circular prolapse. TST minimally invasive surgery uses a special anorectoscope to form different open-loop windows, uses an anastomosis probe to lock the hemorrhoids, adjusts the resection range of the hemorrhoid mucosa according to the size and number of the hemorrhoids, and maximizes the protection of the normal function of the anus.
TST surgery follows the formation mechanism of human hemorrhoids and is designed according to the physiological and pathological structure of hemorrhoids. It aims to correct the pathophysiological changes of hemorrhoids, instead of removing all the anal cushions, leaving normal anal cushions and mucosal bridges, which can reduce Surgical trauma, to maximize the maintenance of the fine sensation and contraction function of the anus, minimize postoperative anal discomfort, shorten the treatment time, and make hemorrhoid surgery more minimally invasive.
TST technology is currently the latest technology for the treatment of hemorrhoids. It is based on the PPH technology to improve the original surgical procedure. It is characterized by simple operation, mild postoperative pain (almost painless), and few complications. The recovery time is short, the curative effect is good, and the patient satisfaction is high.
TST technology comparison
TS technique is based on the theory of "segmented tooth ligation" in traditional Chinese medicine. It takes advantage of its reasonable preservation of the parts and number of skin bridges and mucosal bridges, as well as the tooth-shaped distribution of the ligation area. Combined with PPH surgery, the use of stapler resection Moving down the mucosa and submucosal tissues above the anal pad is a beneficial combination of traditional Chinese medicine and modern medicine in the field of minimally invasive treatment of hemorrhoids in anorectal surgery.
1. TST surgery uses special anoscopes to form different open-loop windows, which only expose the mucosa in the hemorrhoid area, which is more targeted.
2. TST surgery adopts segmented resection and anastomosis, which can intermittently preserve the normal rectal mucosa, which can effectively prevent postoperative anastomotic stenosis.
3. The number of titanium nails implanted in TST surgery is small, which may reduce the discomfort of the anus caused by titanium nails after surgery.
TST technical characteristics
TST minimally invasive and painless technology is developed on the basis of PPH technology. During the treatment, the prolapsed part of the hemorrhoid mucosa is accurately removed, and the integrity of the mucosa and anal cushion near the largest anorectal dentate line is retained, and the normal mucosal bridge is retained. , It maintains the fine sensation and contraction function of the anus to the greatest extent, and reduces surgical trauma.
TST can adjust the resection range of the hemorrhoids according to the number and size of hemorrhoids, which is safe, controllable and achieves good therapeutic effects.
TST is the continuation and extension of the minimally invasive method for hemorrhoids. It has the advantages of less trauma, less postoperative pain, fast recovery, and extremely low postoperative complications and recurrence rate. After clinical treatment effect evaluation and post-operative follow-up of nearly 1,000 cases, the patients were almost painless throughout the treatment, and they could recover within 3-5 days after surgery.
Precise positioning: With a special anoscope, the prolapsed mucosa can be accurately positioned, and the prolapsed hemorrhoid mucosa can be selectively removed successfully and safely, which conforms to the theory of lowering the cushion and reduces surgical trauma.
Slight pain: Traditional surgery is performed in the anal cushion area controlled by the body nerves, which is sensitive to cutting and severe pain. TST surgery is performed in the rectal mucosal area controlled by autonomic nerves. It is not sensitive to cutting, so the surgical pain is mild.
High safety: TST technology treatment will not leave scars, will not damage the physiological function of the anal cushion, will not damage the normal structure and appearance of the rectum and anal canal, and also avoid complications such as anal stenosis and incontinence. Compared with traditional treatment methods, the treatment is safer.
