more post-operative analgesia. Return of bowel function was faster with in situ repair. It was found that between unlocked single-layer closure and double-layer closure, there is no difference in risk of uterine rupture, however the risk of rupture is increased with a locked single-layer suture. Following the repair of the incision, a scar defect may form, which is defined as a thinning of uterine muscle at the incision site. These uterine scar defects are associated with increased risk of uterine rupture and scar separation. Scar defects may increase the risk of complications such as abnormal bleeding, pain, ectopic pregnancy, and infertility. During caesarean section Caesarean sections require a large incision of the uterus, which can lead to complications such as blood loss, postoperative pain, anaemia due to continuing blood loss, fever and possible wound infection, breastfeeding issues, difficulty passing urine, future fertility problems, and/or possible complications in future pregnancies including uterine rupture. During fetal surgery In fetal surgery, without inhibition of uterine contractions, uterine irritability and premature labor are complications that occur very frequently in of hysterotomy cases. It can be inhibited by anti-contraction medications. Preterm birth and early membrane rupture (PPROM) are common risks for fetal therapies. For most cases, fetoscopic surgery, which minimizes the damage to the uterus, is preferred to mitigate risks and complications. Membrane sealing and fixation has been investigated for reducing PPROM risk, but it has not been found to be clinically beneficial. Scar ectopic pregnancy Scar ectopic pregnancy is a rare form of ectopic pregnancy, however, when it does occur it causes complications in pregnancy such as abnormal uterine bleeding and uterine rupture. The mechanism of how scar ectopic pregnancy still remains unknown. However, the possibility that defects may form to the scarring from previous procedures/traumas such as caesarean section, dilation, hysterotomy, abnormal placentation can cause scar ectopic pregnancy. Hysterotomy abortion There are two categories of complications with surgical abortions, minor and major. Minor complications are procedural pain, bleeding, infection and common anesthesia complications. The more serious and major complications include hemorrhage, sepsis, peritonitis, deep vein thrombosis and death. Types There are many different types of hysterotomies depending on the location and direction of the incision. Typically, a low transverse incision is preferred during a caesarean section. This area of the uterus has less vasculature and therefore provides lower risk of hemorrhage during the procedure for the patient. Incisions in the lower area of
