Many pregnant mothers are at a loss as to whether to make a horizontal or vertical abdominal incision for a cesarean delivery, and most young mothers choose a horizontal incision for aesthetic reasons. But is it better to have a horizontal or vertical abdominal incision? What are the pros and cons of each? The horizontal incision is about 3 to 4 cm above the pubic symphysis, and the skin, subcutaneous tissue and fascia are all cut horizontally, but when it comes to the rectus abdominis muscle, it is cut longitudinally at the midline into the abdominal cavity. The longitudinal incision is made between the navel and the pubic symphysis in the middle of the longitudinal dissection into the abdominal cavity. In the incision of the uterine wall, a transverse incision of the lower uterine segment is now commonly used for cesarean delivery. The two types of incisions differ in terms of aesthetics, time of fetal delivery, exposure of the operative field, postoperative adhesions, and ease of re-operation due to the different sites chosen. The advantages of the horizontal incision: 1. Because the incision is low and can be hidden underneath the underwear and in the same direction as the skin, it is preferred by young mothers; 2. Disadvantages of longitudinal incision: 1.Surgery is time-consuming, the delivery time of fetus is longer than that of longitudinal incision, the requirement of anesthesia is high, and it is more suitable for elective surgery; 2.The extension of incision is limited, and the exposure of operative field is limited, which is not conducive to extensive intraoperative investigation, and if there is a gynecological surgery indication after delivery, another longitudinal incision is needed; 3.The delivery of fetal head is affected by the incision, which is more difficult than that of longitudinal incision; 4.The adhesion of each layer is heavy after surgery, and it is relatively difficult to operate again. Advantages of longitudinal incision: 1. The time from skin incision to delivery of fetus is shorter, especially for emergency cases, such as cord prolapse and severe intrauterine distress, which require immediate delivery of fetus. 2, the operative field is wider than the transverse incision, and it is easy to extend, so the longitudinal incision is appropriate in case of emergency, combined tumor or intraoperative investigation with surgical indications; 3, the chance of tissue adhesions is low, and the longitudinal incision can be chosen for those who have the requirement to continue childbirth Disadvantages of the longitudinal incision: 1, the scar of the abdominal wall incision is obvious, especially in patients with scar; 2, the pulling sensation is heavy, and the pain is more obvious; 3, the tension of the incision is greater, which is not conducive to healing of the incision.
