hemorrhoids ligation,Selective supramucosal resection (TST)

    Introduction: Selective upper mucosal resection (TST surgery): It is a new type of technology developed recently on the basis of PPH operation. It not only corrects the pathophysiological changes of hemorrhoids, but also removes all the anal pads and retains them. The normal anal cushion and mucosal bridge are maintained, thereby maintaining the fine functions of the anus, reducing surgical trauma, shortening the treatment time, and making hemorrhoid surgery more minimally invasive.

    Technical principle: Selective supramucosal resection (TST surgery) uses a special anoscope to form different open-loop windows, only exposing the mucosa of the hemorrhoid area, which is more targeted; retaining the mucosal bridge between the hemorrhoids and no Symptoms: The normal mucosa in the hemorrhoid area avoids the formation of circular scars and effectively prevents anal stenosis; at the same time, it reduces the interference and stimulation of the transitional epithelial domain of the rectum and anal canal, and reduces the discomfort of postoperative bulging.

    Application range: It has a very ideal therapeutic effect on internal hemorrhoids, external hemorrhoids, mixed hemorrhoids, ring hemorrhoids, severe hemorrhoid prolapse, prolapse and so on. Especially used for the treatment of internal hemorrhoids of degree III and IV.

    Technical advantages: TST technology is characterized by simple operation, mild postoperative pain (almost painless), fewer complications, short recovery time, good curative effect, does not affect work and study, and high patient satisfaction.

    Contraindications: It is not recommended for pregnant women, children, intractable constipation, pelvic tumors, portal hypertension, Bu-Ka syndrome or those who cannot tolerate surgery.

    TST surgical instruments: The anoscopes of TST instruments are divided into: single-opening anoscope, double-opening anoscope and three-opening anoscope.
