How does anal fissure operation do picture?

summary

Anal fissure refers to the full-thickness longitudinal split of anal skin or ulceration. The clinical manifestations were anal periodic pain, bleeding and constipation. Anal fissure is an independent disease of anorectum, which is qualitatively different from chancre and tuberculous ulcer. Sometimes it takes only one second for anal fissure to form, but it takes a long time for chronic ulcer to form. Now tell us how to do anal fissure surgery picture?

How does anal fissure operation do picture?

The skin and subcutaneous tissue were cut in "△" shape from both sides of anal fissure. The bottom of the incision was 1.5-2CM away from the anal margin, and the top was 0.5cm away from the tooth line. Tissue forceps were used to lift the skin and subcutaneous tissue of the incision, and the subcutaneous sclerotic fibrous tissue was sharply separated upward. If there were hemorrhoids and hypertrophic anal papilla, they were removed at the same time. This method is suitable for old anal fissure without anal stricture.

Posterior internal sphincterotomy was performed in the posterior midline. The incision was 0.5-1.0 cm from the dentate line down to the outside of the anal margin. The lower edge of the internal sphincter and the lower part of the skin of the external sphincter were cut longitudinally. The incision was moderately extended to the outside of the anal margin, and the ulcer edge tissue was trimmed to form a "V" shaped wound surface with a small top and a large bottom. This method is suitable for old anal fissure with anal stenosis, but if the incision is too small and the drainage is not smooth, it is easy to lead to "keyhole" deformity, so this method can be replaced by lateral internal sphincterotomy.

In lateral internal sphincterotomy, a 2cm long arc or radial incision was made at 1-2cm outside the left anal margin. The small curved hemostatic forceps were used to separate the subcutaneous part of the anal canal from the internal sphincter to the plane of the tooth line, and then the lower edge of the internal sphincter to be cut was picked out and cut off. The skin incision was sutured. Attention should be paid to eliminating congestion and leaving no dead space during suturing.
