8.7 Technique Guidance

8.7.1 For OB/GYN Procedures
1 . The endocervix may not be included in the loop excision, and the results of endocervical curettage (ECC)
may not be predictive of either residual or invasive disease after loop excision procedures .
If the ECC is positive for dysplasia, a standard cone biopsy should be considered .
2 . Loop Electrosurgical Excision Procedures performed with small diameter wire Loop Electrodes
produce multiple small pieces of cervical tissue and may provide a less acceptable tissue specimen for
histopathologic analysis .
3. Larger lesions involving multiple quadrants of the cervix are more difficult to remove with Loop
Electrodes .
8.7.2 For Severed Vessels
1 . Clamp the bleeder with a hemostat .
2 . Using electronically generated current, touch a Ball Electrode to any part of the hemostat .
3 . Depress the Foot Switch Pedal to activate the current for several seconds, then release the Pedal and
remove the electrode . Be sure the current is set as high as is necessary to achieve coagulation .
4 . After the application of coagulating current, remove the hemostat . Bleeding should have stopped;
if not, repeat the procedure . Suture ligation may be required if R/F is unsuccessful .
5 . When using electronically generated current, it is safe to hold the hemostat in a gloved hand while holding
the electrode handle in the other during this procedure .
8.7.3 For Anesthesia
Adequate anesthesia is indicated for all electrosurgical procedures . It is usually advisable to anesthetize tissue
adjacent to the intended operative site in the event it becomes necessary to extend the operative area .
8.7.4 For Biopsy
The use of electrosurgery for cervical biopsy has advantages in that it seals the capillaries and lymphatics as
it cuts . Whenever possible, the specimen should include two to three millimeters of attached normal tissue .
Small (up to one half inch) masses should be removed in one piece . Using a cutting current at a relatively
high setting and a Needle Electrode, incise all around the mass in an elliptical pattern, including two to three
millimeters of attached normal tissue .
Small masses may also be removed by using a suitable Loop Electrode – large enough so that it can
excise the mass as well as two to three millimeters of attached normal tissue at the same time .
Specimens from larger masses should be taken in the form of wedges . Using a Needle Electrode and cutting
current, start at the apex of the wedge at the center of the suspicious mass . The base of the wedge should
include two to three millimeters of attached normal tissue .
Section 9 Powering Down the LEEP PRECISION Integrated System
1 . At the completion of each procedure, activate the system to ensure safe particle containment . Using
gloves and a mask, remove the Pre-Filter, the Reducer, and the used section of Suction Tubing and
discard into an infectious waste receptacle (see Cautions) . The CooperSurgical Smoke Evacuator
should be stored with a new Pre-Filter and Reducer in place on the ULPA filter.
2 . Turn off the Power Switch (on the LEEP PRECISION Integration Unit) and unplug from the wall outlet .
3 . Dispose of the used sterile Active Electrode (Pencil) and Patient Return Electrode (Dispersive Electrode) .
4 . Do not throw out the Adapter that is used for the Foot Switch-Operated Electrode . This Adapter is needed
each time a new Foot Switch-Operated Electrode is used for each subsequent procedure .
5 . If the Reusable Cable was used for the Patient Return Electrode, retain it for each subsequent use of a
new Patient Return Electrode .
