the loop electrosurgical excision method (leep) is one of the most usually used approaches to treat excessive grade cervical dysplasia (cin ii/iii, hgsil) discovered on colposcopic exam. in the uk, it's miles called large loop excision of the transformation sector (lletz).
leep has many blessings including low cost, high fulfillment price, and simplicity of use. the system can be achieved in an workplace putting and normally simplest requires a nearby anesthetic, although sometimes iv sedation or a fashionable anesthetic is used.
whilst acting a leep, the medical doctor uses a twine loop via which an electric modern-day is surpassed at variable energy settings. diverse sizes and styles of loop can be used depending on the dimensions and orientation of the lesion. the cervical transformation quarter and lesion are excised to an ok intensity, which in maximum cases is at the least eight mm, and lengthening four to 5 mm past the lesion. a second bypass with a greater slender loop also can be completed to acquire an endocervical specimen for in addition histologic assessment.
the leep technique results in some thermal artifact in all specimens obtained due to the use of electricity which simultaneously cuts and cauterizes the lesion, however this doesn't usually intervene with pathological interpretation.
complications are less frequent in contrast to a cold-knife conization however can encompass infection and hemorrhage.
