One of the most common questions women ask before fibroid surgery is a practical one: if my fibroid is the size of a grapefruit, how does a surgeon remove it through an incision the size of a buttonhole?
It is a reasonable question, and the answer involves a technique called contained morcellation. Used by fellowship-trained, minimally invasive gynecologists, this approach allows even large or bulky fibroids to be removed through small laparoscopic openings, avoiding the longer recovery, greater blood loss, and larger scar associated with traditional open surgery.
This article explains how contained morcellation works, why the containment step matters, what the pre-surgical evaluation process involves, and what patients can expect during recovery. It is written for women who have been told their fibroids are large and want to understand whether minimally invasive surgery is still an option for them.
Key Takeaways
- Large fibroids can often be removed through small laparoscopic incisions using a technique called contained morcellation.
- A special surgical bag encloses the fibroid tissue before it is divided, preventing any spread within the abdominal cavity.
- Pre-surgical evaluation includes imaging and, when appropriate, tissue sampling to screen for rare but important diagnoses before morcellation proceeds.
- Most patients go home the same day and return to normal activity within one to two weeks.
- Not every patient is a candidate for minimally invasive fibroid removal. Fibroid size, number, and location, along with individual anatomy and medical history, all factor into the decision.

What Is Morcellation, and Why Is It Used?
Morcellation is a surgical technique that divides large tissue into smaller pieces so they can be removed through narrow laparoscopic or robotic incisions. In gynecologic surgery, it is most commonly used during myomectomy (fibroid removal) and hysterectomy, when the uterus or fibroid is too large to be extracted intact through a small incision.
The technique has existed for decades, but its use has evolved significantly following guidance from the U.S. Food and Drug Administration (FDA) and professional societies, including the AAGL. The primary concern that prompted that guidance was the theoretical risk of spreading undetected cancerous or precancerous tissue if a fibroid that turned out to be malignant were morcellated in an uncontained manner. In response, surgeons trained in MIGS now use a contained system: the fibroid is placed inside a sealed bag before any morcellation takes place.
This distinction between open morcellation and contained morcellation is the most important thing to understand when evaluating your surgical options.
Contained Morcellation vs. Open Morcellation: What Changed
Open Morcellation (Historical Approach)
In older practice, morcellation was performed directly inside the abdominal cavity without containment. A powered or manual device divided the tissue while it was exposed to the peritoneal environment. If a fibroid harbored an unsuspected malignancy, this approach carried a risk of disseminating cells throughout the abdomen.
In 2014, the FDA issued a safety communication discouraging the use of power morcellators for the vast majority of women undergoing fibroid surgery, citing this dissemination risk. That guidance prompted widespread adoption of contained techniques among experienced minimally invasive gynecologists.
Contained Morcellation (Current Standard Among MIGS Surgeons)
With contained morcellation, the fibroid or uterine tissue is placed inside a thick, impermeable surgical bag before it is divided. The bag is then partially extracted through one of the small laparoscopic incisions, and the tissue inside is systematically reduced into strips or segments using precise instruments while remaining fully enclosed.
Nothing spills. Nothing contacts the peritoneal surfaces. The sealed environment is the defining feature of the technique, and it directly addresses the concern that prompted the FDA guidance.
MIGS-trained surgeons who perform high volumes of complex fibroid cases have refined contained morcellation into a reliable, reproducible technique. Dr. Kim uses this approach as a standard part of her fibroid surgery practice.
Why Pre-Surgical Evaluation Matters
The safety of contained morcellation depends not only on the surgical technique itself but on the evaluation that takes place before the procedure begins. Because the primary concern with morcellation is the rare possibility of an undetected malignancy, a thorough pre-operative workup is essential.
Imaging
Pelvic ultrasound and, when indicated, MRI are used to characterize the size, number, and location of fibroids and to identify any imaging features that might raise concern about the nature of the tissue. Fibroids that grow very rapidly, have atypical imaging characteristics, or occur in the context of other risk factors warrant closer evaluation before proceeding.
Bloodwork and Endometrial Sampling
Abnormal uterine bleeding in conjunction with a uterine mass sometimes warrants endometrial sampling (biopsy) to evaluate the uterine lining. This is particularly true for patients in perimenopausal or postmenopausal age groups or those with additional risk factors for endometrial pathology.
Shared Decision-Making
Before any surgical plan is finalized, a comprehensive consultation is conducted to review the diagnostic findings, explain the planned approach, and outline the alternatives. The goal is for every patient to understand her diagnosis, the reasoning behind the recommended surgical technique, and the realistic outcomes, including the very small but nonzero possibility of unexpected findings at the time of surgery.
Patients who have questions about morcellation specifically, including the FDA guidance, the containment system, and how their individual risk profile affects the decision, should raise those questions explicitly during the pre-surgical consultation. A well-prepared surgeon will welcome those questions.
How Contained Morcellation Is Performed: A Step-by-Step Overview
For patients who want to understand the mechanics of the procedure, here is a plain-language walkthrough of what happens in the operating room.
-
Anesthesia and positioning. The procedure is performed under general anesthesia. You will not be awake. You are positioned on the operating table in a way that allows the surgeon optimal access to the pelvis.
-
Laparoscopic entry. Small incisions, typically three to four, each approximately half a centimeter to one centimeter in length, are made in the abdomen. A camera (laparoscope) is inserted through one, and the surgical instruments through the others.
-
Fibroid identification and detachment. Using the camera and instruments, the surgeon locates the fibroid and carefully detaches it from the uterus, controlling blood supply to minimize bleeding. The uterus is repaired (sutured) at the removal site.
-
Bag placement. Once the fibroid is detached, it is placed inside a specialized containment bag within the abdominal cavity. The opening of the bag is then brought out through one of the incisions and secured, creating a sealed environment.
-
Morcellation inside the bag. With the fibroid fully contained, the surgeon uses instruments to systematically reduce it into strips or segments within the sealed bag. These pieces are removed through the incision while the bag maintains its integrity throughout.
-
Closure. The small incisions are closed. Most require only a few stitches or adhesive strips. Patients are monitored briefly in recovery and typically discharged the same day.
Patient Outcomes: What Minimally Invasive Fibroid Removal Means for Recovery
The benefits of avoiding open abdominal surgery are substantial and well-documented. The following comparison reflects the typical difference between an open myomectomy (laparotomy) and a minimally invasive myomectomy using contained morcellation when performed by a fellowship-trained MIGS gynecologist.
| Factor | Open (Laparotomy) | Minimally Invasive (MIGS) |
|---|---|---|
| Incision length | 4–8 inches (10–20 cm) | 3–4 keyhole incisions (~0.5–1 cm each) |
| Hospital stay | 2–4 days | Same-day or overnight |
| Return to activity | 4–6 weeks | 1–2 weeks |
| Blood loss | Higher | Lower |
| Infection risk | Higher | Lower |
| Scar visibility | Prominent | Minimal, fades over time |
| Tissue containment | Not required | Contained bag morcellation |
These differences translate into meaningful quality-of-life advantages. Women who undergo minimally invasive myomectomy can typically return to desk work within one to two weeks, resume light exercise within three to four weeks, and experience less postoperative discomfort requiring pain medication than those who undergo open procedures.
For women with demanding professional schedules, family responsibilities, or simply a preference to minimize disruption to daily life, the recovery differential between open and minimally invasive surgery is one of the most important factors in the surgical decision.
Who Is a Candidate for Minimally Invasive Fibroid Removal?
Contained morcellation and minimally invasive myomectomy are appropriate for many women with symptomatic fibroids, but not for all. Candidacy depends on a combination of factors that are evaluated during the pre-surgical consultation.
Factors That Support Minimally Invasive Candidacy
-
Symptomatic fibroids that have not responded adequately to non-surgical management
-
Fibroid characteristics (size, number, location) that are technically amenable to laparoscopic or robotic removal
-
No imaging features or clinical risk factors raising significant concern for malignancy
-
A desire to preserve the uterus (myomectomy rather than hysterectomy)
-
No contraindications to general anesthesia or laparoscopic surgery
Situations That May Require a Different Approach
-
Fibroids that are extremely numerous (some sources suggest more than 10 to 15 may increase operative complexity significantly)
-
Deeply embedded intramural fibroids in locations near major vessels or the cornua that pose elevated surgical risk laparoscopically
-
Imaging findings or clinical history that raise concern about the nature of the tissue (in these cases, open removal without morcellation may be the safer choice)
-
Very large uterine size that limits visualization and instrument access
It is also worth noting that a previous myomectomy or other abdominal surgery does not automatically disqualify a patient from a minimally invasive approach, though adhesions and altered anatomy from prior surgery require careful evaluation.
Understanding the FDA Guidance on Morcellation
In 2014, the FDA issued a safety communication warning against the use of laparoscopic power morcellators in the majority of women undergoing hysterectomy or myomectomy for uterine fibroids. The concern was that if a woman had an unsuspected uterine sarcoma or other malignancy, power morcellation in an uncontained setting could spread cancerous cells and worsen her prognosis.
It is important to understand what this guidance did and did not say. The FDA guidance addressed uncontained power morcellation. It did not prohibit morcellation categorically, and it explicitly acknowledged that contained morcellation systems were under evaluation as a potential method of preserving the benefits of minimally invasive surgery while addressing the dissemination risk.
Subsequent FDA guidance and updated labeling for certain contained morcellation systems has reflected the evidence that containment substantially mitigates the dissemination risk. Today, among MIGS surgeons who perform high-volume fibroid surgery, contained morcellation within a sealed bag is the accepted method for tissue extraction when morcellation is clinically indicated.
The absolute risk of an unsuspected uterine sarcoma in a woman presenting with presumed uterine fibroids is very low, estimated in the literature at approximately 1 in 500 to 1 in 1,000. The pre-surgical evaluation process described above is designed to identify the characteristics that would elevate this risk and prompt a different surgical strategy.
Fibroid Surgery at Dr. Kim’s Upper East Side Practice
Dr. Annie Kim is a fellowship-trained minimally invasive gynecologist practicing at 877 Park Avenue on the Upper East Side. She completed her two-year AAGL fellowship at Montefiore/Albert Einstein, where she trained in advanced laparoscopic and robotic techniques for complex gynecologic conditions including large and multiple uterine fibroids.
Her practice is MIGS-only, meaning she does not practice obstetrics. Every operating day is devoted to gynecologic surgery, which means her surgical volume in procedures such as laparoscopic myomectomy is concentrated rather than divided across clinical domains.
Women who have been told their fibroids are too large for minimally invasive surgery, or who are concerned about what morcellation involves, are encouraged to schedule a consultation. The evaluation process will determine whether contained laparoscopic removal is an option for their specific anatomy and fibroid profile, and if not, what the least invasive appropriate alternative would be.
Frequently Asked Questions
Can large fibroids really be removed without open surgery?
In many cases, yes. A fellowship-trained MIGS gynecologist can use contained morcellation to remove large fibroids through small laparoscopic incisions. Whether this is possible depends on fibroid size, number, and location, as well as individual anatomy and the presence or absence of imaging features that might raise concern. A pre-surgical consultation is the best way to determine candidacy.
What is contained morcellation?
Contained morcellation is a technique in which fibroid or uterine tissue is placed inside a sealed, impermeable surgical bag before being divided into smaller pieces for removal. The containment bag prevents any tissue from contacting the peritoneal cavity during the morcellation process, which is the key safety distinction from older uncontained techniques.
Is morcellation safe after the FDA warning?
The FDA’s 2014 guidance specifically addressed uncontained power morcellation. Contained morcellation systems, which enclose tissue in a sealed bag, were developed in direct response to that guidance. Among MIGS surgeons performing high-volume fibroid surgery, contained morcellation is the accepted standard when morcellation is clinically indicated. The pre-surgical evaluation process is designed to identify patients for whom morcellation would not be appropriate.
What is the recovery like after laparoscopic fibroid removal?
Most patients who undergo minimally invasive myomectomy with contained morcellation go home the same day. Return to light activity typically occurs within one to two weeks, and return to exercise within three to four weeks. This compares favorably to open myomectomy, which typically requires four to six weeks of recovery and involves a larger abdominal incision.
What is a myomectomy, and how is it different from a hysterectomy?
A myomectomy is a fibroid removal procedure that leaves the uterus intact. It is the preferred surgical approach for women who wish to preserve their uterus, whether for fertility reasons or personal preference. A hysterectomy removes the uterus entirely. Both procedures can be performed using minimally invasive techniques by a MIGS-trained gynecologist.
How does the surgeon know whether morcellation is safe for me specifically?
The pre-surgical evaluation includes pelvic imaging (ultrasound and sometimes MRI) and, when appropriate, endometrial sampling. These tests allow the surgeon to characterize your fibroids and screen for features that might raise concern about the nature of the tissue. Patients with imaging findings or clinical risk factors that suggest an elevated concern for malignancy would typically be offered an alternative approach rather than morcellation.
Do I need a referral to see a MIGS gynecologist for fibroid evaluation?
Most MIGS practices accept self-referred patients for consultations. You do not typically need a referral from another provider, though confirming your insurance coverage before scheduling is advisable. If you have recent pelvic imaging such as an ultrasound or MRI, bringing those records to your first visit will make the consultation more productive.
What symptoms suggest I should seek a surgical evaluation for fibroids?
Symptoms that commonly prompt a surgical consultation include heavy or prolonged menstrual bleeding, pelvic pressure or pain, frequent urination caused by fibroid pressure on the bladder, difficulty with bowel function, and pain during intercourse. Fibroids that are causing significant symptoms and have not responded to hormonal management are generally appropriate candidates for a surgical discussion.
