External stripping and internal ligation
The hemorrhoids are stripped and separated, and then ligated with silk thread, the hemorrhoids are avascular and necrotic and fall off to achieve the purpose of treatment. When the hemorrhoids are huge and the number is large, especially when the hemorrhoids are prolapsed in a circular shape, this kind of operation is limited, painful, incomplete stripping and ligation, and even another operation. Postoperative edema is easy; if the blood vessel is not completely closed when the ligature falls off, it will cause hemorrhage; too many ligatures will cause anal canal stenosis.
RPH hemorrhoids band ligation
It is generally similar to external stripping and internal ligation, except that the ligation line is replaced with a set of rubber bands or elastic lines, and the risk of bleeding and stenosis is greatly reduced.
It can be said that it is the best surgical method for the treatment of hemorrhoids, especially circular hemorrhoids. The treatment is thorough and the effect is obvious, but the cost is high.
As a further method of PPH operation, for huge circular hemorrhoids, PPH cutting space is limited, so two staplers are used to remove more mucosa, which is suitable for circular huge hemorrhoids, but general hemorrhoids are not suitable.
