What is a Partial Hysterectomy?
A partial hysterectomy, also called subtotal or supracervical hysterectomy, is a surgical procedure in which the uterus is removed while the cervix is retained 1, 2.
Anatomical Definition
The procedure involves:
- Complete removal of the uterine body (corpus)
- Preservation of the cervix (the lower portion of the uterus that extends into the vagina)
- The cervix remains attached to the vaginal vault 1, 3
This contrasts with total hysterectomy, where both the uterine body and cervix are removed together.
Surgical Approaches
Partial hysterectomy can be performed through multiple routes 3, 4:
- Laparoscopic supracervical hysterectomy (LASH) - minimally invasive approach using small abdominal incisions
- Abdominal approach - through a larger abdominal incision
- Vaginal route - through the vagina 5
Key Clinical Considerations
Advantages of cervical preservation:
- Shorter operative time (approximately 13 minutes less than total hysterectomy) 6
- Reduced intraoperative blood loss (approximately 81 ml less) 6
- Shorter hospital stay (approximately 0.4 days less) 6
- Potentially simpler dissection in cases with distorted cervical anatomy 2
Important disadvantages:
- Persistent cyclical vaginal bleeding occurs in approximately 14% of patients (versus 1.2% with total hysterectomy) 6
- Continued need for cervical cancer screening with Pap smears 1, 2
- Risk of future cervical pathology requiring additional procedures
Outcomes that are equivalent between partial and total hysterectomy:
- Sexual satisfaction and function 6
- Quality of life scores 6
- Persistent pain rates 6
- Blood transfusion requirements 6
Critical Pitfall
Women must be counseled preoperatively that they will continue to require regular cervical cancer screening after partial hysterectomy 1. This is a common source of patient confusion and dissatisfaction when not adequately discussed beforehand.
