A lower (uterine) segment Caesarean section (LSCS) is the most commonly used type of Caesarean section.[1] It includes a transverse cut 1-2 centimetres above the attachment of the urinary bladder to the uterus, called the Pfannenstiel incision in the lower segment. This type of incision results in less blood loss and is easier to repair than other types of Caesarean sections.

It may be transverse (the usual) or vertical in the following conditions:

  • presence of lateral varicosities
  • constriction ring to cut through it
  • deeply engaged head

  • The location of an LSCS is beneficial for the following reasons:

  • peritoneum is more loosely attached to the uterus
  • contraction is less than in upper part of uterus
  • healing is more efficient
  • sutures are intact (less problem with suture loosening)

    Most bleeding takes place from the angles of the incision, and forceps can be applied to control it. Green Armytage forceps are specifically designed for this purpose.
    Although the incision is made using a sharp scalpel, care must be taken not to injure the foetus, especially if the membranes are ruptured, or in emergencies like abruption. The incision can be extended to either sides using a scissor or by blunt dissection using hands. While using the scissors, the surgeon should ensure that a finger is placed underneath the uterus so that the foetus in protected from unintentional injury. If blunt dissection is done, intraoperative blood loss can be minimized. In cases where Pfannenstiel incision cannot be done (such as large baby), Kronig incision (low vertical incision), classical (midline), J or T shaped incisions may be used to incise the uterus.
