anal fissure resection

1. Has an anal fissure triple sign. 2. Chronic old anal fissure that is ineffective for long-term non-surgical treatment. Treatment of diseases: anal fissure Indication 1. Has an anal fissure triple sign. 2. Chronic old anal fissure that is ineffective for long-term non-surgical treatment. Preoperative preparation No special preparation is required. Surgical procedure 1. Position: The position of the stone. 2. Exploring the crypt: After anesthesia, disinfection, and gloves, use the finger to apply a sterile liquid paraffin or soap to gently spread the anus. Use an anoscope or crypt hook to detect, if it is found that the anal fissure communicates with the crypt or has a sneak mucosal edge, the incision is dilated. 3. Incision: 2cm from the tooth line to the anus mouth, a prismatic or fan-shaped incision around the anal fissure ulcer surface, to reach the basal layer of the ulcer. 4. Resection of the anal fissure: The edge of the ulcer was clamped with a small vascular clamp along the incision, and the basal part of the ulcer was sharply separated. All the anal fissures and the crypts with lesions, the enlarged anal papilla and the sag were removed. The advantage of this method is that the lesion is completely resected, the wound surface is wide, and the drainage is smooth, which facilitates the growth of granulation tissue from the substrate. 5. Cut off the external sphincter subcutaneous group: Because the anal fissure often leads to long-term muscle fibrosis of the sphincter, the subcutaneous group of the external anal sphincter is firstly victimized, hardened and loses elasticity, which hinders the drainage of the sphincter. A transverse cord can be placed in the middle of the wound, which can be cut at the near tooth line. 6. Wrap the wound: After compression or ligation, the wound is opened and covered with Vaseline gauze.
