Cervical conization is an excisional surgical procedure employed to diagnose cervical dysplasia and for therapeutic purposes in some patients. Also known as cone biopsy, this procedure involves the removal of a cone-shaped section of the cervix, encompassing the entire transformation zone and any suspicious cervical lesions. This excised tissue is subsequently subjected to histological analysis. When all cervical dysplastic lesions are contained within the specimen, the procedure serves both diagnostic and therapeutic purposes. Cervical conization can be conducted using various techniques, such as cold knife cone (CKC), laser conization, and the loop electrosurgical excision procedure (LEEP), which is also referred to as loop excision of the transformation zone (LLETZ). Typically, diagnostic excisional procedures are performed when a histological evaluation is required, such as in cases of discordance between cervical cytology and biopsy findings, evidence of severe cervical dysplasia, or the inability to visualize the cervical transformation zone fully. LEEP and CKC are the most commonly utilized methods for cervical conization, and studies have shown them to be equally effective in diagnosing and treating cervical dysplasia. Therefore, choosing an excisional modality is usually based on individualized clinical factors. CKC is performed with a scalpel, typically under general or regional anesthesia, and is conventionally believed to yield a larger specimen with less thermal damage to the margins compared to other excisional methods. This activity for healthcare professionals is designed to enhance their competence in recognizing indications and contraindications for CKC, understanding the risks, benefits, and complications associated with the procedure, and mastering the technique involved. Additionally, it will review the role of the interprofessional team in caring for patients with cervical intraepithelial neoplasia who undergo CKC, ultimately leading to improved patient outcomes. Objectives: Identify the indications for the cervical cold knife cone procedure. Identify the steps in the cervical cold knife cone procedure. Assess and identify the common complications of the cervical cold knife cone procedure.

Cervical conization is an excisional surgical procedure used to diagnose cervical dysplasia; it may also be therapeutic in some patients. Conization, or cone biopsy, removes a cone-shaped portion of the cervix, encompassing the transformation zone and suspicious cervical lesions, for subsequent histological analysis.[1] The procedure is considered therapeutic and diagnostic if all cervical dysplastic lesions are contained within the specimen. Modalities like cold knife cone (CKC), laser conization, loop electrosurgical excision procedure (LEEP), or loop excision of the transformation zone (LLETZ) can be used for cervical conization.[1] Generally, diagnostic excisional procedures are performed when a specimen is needed for histological evaluation, often due to discordance between cervical cytology and biopsy results, severe cervical dysplasia, or incomplete visualization of the cervical transformation zone. LEEP and CKC are the most common methods, equally effective in diagnosis and treatment. Clinicians must select the appropriate excisional method based on individual clinical factors. CKC is performed with a scalpel, typically under general or regional anesthesia, and is traditionally believed to produce a larger specimen with less thermal destruction of the margins compared to other techniques.[2][3] This activity for healthcare professionals is designed to enhance the learner’s competence when recognizing the indications and contraindications when considering CKC, the risks, benefits, and complications of the procedure, and the technique used to perform it. Additionally, this activity will review the collaborative role of the interprofessional team in caring for patients with cervical intraepithelial neoplasia who undergo CKC, ultimately leading to improved patient outcomes.

The most significant complication of a CKC procedure is bleeding, either intraoperatively or within the first 2 weeks of the postoperative period. Multiple techniques can manage intraoperative bleeding, including Monsel paste, silver nitrate, packing, or suturing. Major postoperative bleeding occurs in 2% to 17% of patients, depending on the study referenced. Occasionally, a return to the operating room to recauterize or suture the cone bed is required to obtain hemostasis.[20][13] Infections following a CKC procedure are rare, occurring in only 1% of patients; typically, they can be treated with oral antibiotics. Cervical stenosis and cervical insufficiency are late complications associated with this procedure. Cervical stenosis should be evaluated postoperatively if aggressive cauterization was performed or a deep cervical cone specimen was obtained. Cervical stenosis can be treated with dilation of the endocervical canal. Cervical stenosis is more common in postmenopausal women.[20] Data is mixed regarding the risk of preterm delivery and perinatal mortality associated with excisional conization procedures; no randomized controlled trials exist. Most studies indicate that the CKC procedure is associated with a greater risk of preterm delivery and intraamniotic infection than the LEEP procedure because of the greater depth of cervical excision. A recent study found that conization depths of ≥18 mm increased the risk for early-onset neonatal sepsis and intraamniotic infection; however, most other studies have also found that increased conization length was associated with a higher incidence of preterm labor. Additionally, undergoing more conization procedures is linked to an increased risk of preterm birth.[21][22][19][18][13][23] Therefore, limiting the amount of excised cervical tissue is especially important for patients with future pregnancy plans.

CKC is a procedure that involves several members of the healthcare team. CKC is usually performed by a general gynecologist or occasionally a gynecologic oncologist in a hospital operating room or surgical facility. Therefore, anesthesiology clinicians, operating room nurses and technicians, presurgical and postsurgical nurses, and pathologists all have essential roles in caring for a patient undergoing a CKC. Interprofessional communication and care coordination are critical from the planning to the performance of the procedure to ensure optimal patient outcomes. Furthermore, adequate patient education and follow-up by the gynecology and primary care clinicians should provide the patient with a thorough understanding of the risks and benefits of the procedure, including future fertility risks, the prevention of cervical cancer with condom use and HPV vaccination, and adhering to the recommended cervical cancer screening guidelines.

Nurses, nurse practitioners, and physician assistants are essential to inform and counsel patients before, during, and after a conization procedure. Nursing is important in the care and support of patients with cervical dysplasia. Nurses provide education, counseling, and assistance throughout the diagnostic, treatment, and follow-up processes. The role of allied health care includes supportive care, pre and postprocedure care, and follow-up monitoring. Nursing responsibilities and scope of practice may vary depending on the healthcare setting, including local protocols and level of training and expertise. Collaborating with the healthcare team and being updated on evidence-based practices are essential. This collaboration will provide optimal care to individuals with cervical dysplasia and conization treatments.[28]
