The steps of tubal reversal surgery are as follows: i. Abdominal skin disinfection. ii. The abdominal incision is about 4-6 cm long. iii. Cut open the peritoneum, examine the uterus, bilateral adnexa and pelvic cavity, and extract the uterus by clamping the round ligament with tissue forceps. iv. iv. Remove the fallopian tubes and clamp the ends of the original ligature scar with tissue forceps, and pad the tubal area with small gauze. V. Inject saline into the scar with a No. 5 needle to separate the ureter from the plasma membrane layer, cut the plasma membrane layer transversely or longitudinally, and free the ureter. Six, cut away the scar tissue with ophthalmic bending scissors to expose the normal fallopian tube tissue. Use small mosquito-type forceps to clamp the plasma muscle layer at the 12 o’clock of the fallopian tube to expose the luminal opening, and insert the proximal fallopian tube first with a flat needle. Push in saline, such as resistance and leakage, indicating a patent fallopian tube. VII. Measure the horsetail, which is inserted slowly from the proximal end of the fallopian tube to reach the uterine cavity through the interstitium. VIII. The other end of the horsetail is inserted into the distal end of the fallopian tube so that it is slightly exposed at the umbilical end. If there is no bleeding, one stitch can be placed up and down, left and right. X. Interrupted sutures with 7-0 nylon thread to close the plasma membrane layer and remove the cauda equina after the tubal anastomosis. XI. Check for bleeding, and the abdomen can be closed after cleaning the abdominal cavity with warm saline.
