The specific steps of tubal occlusion laparotomy include the establishment of artificial channel, surgical exploration, treatment measures and so on. 1. Establishment of artificial channel: Perforate and ventilate the patient’s abdomen, so that the patient’s abdomen is inflated, which is conducive to the entry of instruments for observation. 2. Surgical exploration: under the direct vision of laparoscopy, to see whether there are adhesions in the pelvis, whether there is fluid in the fallopian tubes, etc., and to adopt different treatments according to the patient’s condition. 3. Treatment measures: free the fallopian tube and other tissues, and inject methylene blue reagent into the fallopian tube to determine whether the fallopian tube is patent or not, if it is not patent, according to different etiology to take different methods to make the fallopian tube patent, such as tubal effusion, can take salpingectomy or fluid puncture, such as fallopian tube adhesion can be corrected by guidewire or surgery. It is recommended that patients take bed rest after surgery, prohibit sexual intercourse within 2 months, avoid strenuous exercise, eat a healthy and light diet, and maintain a good mood, which is conducive to postoperative recovery. If the patient has tubal blockage, it is recommended to consult a doctor in time, under the guidance of the doctor, after perfecting the relevant examination, to clarify the cause of the disease, to determine whether the tubal blockage can be lifted by laparoscopic surgery.
