A Common Surgery with Outsized Consequences

Hysterectomy and myomectomy are among the most frequently performed surgeries worldwide.

Minimally invasive and robotic approaches have delivered clear benefits at the point of care, including shorter hospital stays, faster recovery, and fewer complications.

To remove the uterus or fibroids through small incisions, surgeons use a technique known as morcellation, in which tissue is cut into smaller pieces for extraction during surgery.

However, when tissue is cut without containment, those short-term gains can be offset by downstream harm.

The risks fall into three interconnected categories:

• dissemination of undiagnosed malignancy
• spread of benign tissue, including endometriosis and parasitic fibroids
• legal and financial exposure linked to off-label device use

Crucially, these costs often surface years after the original procedure and rarely where the original cost savings were realized.

Cancer Dissemination: A Known and Preventable Risk

The risk of occult uterine malignancy in women undergoing surgery for presumed benign fibroids is well documented.

The U.S. Food and Drug Administration has estimated this risk at approximately 1 in 350 women, prompting repeated safety communications recommending tissue containment during morcellation.

When morcellation is performed without containment, undiagnosed cancer will be dispersed throughout the abdominal cavity, effectively upstaging disease from localised to disseminated.

The clinical implications are profound, and so are the economic consequences.

Treatment costs for early-stage uterine cancer typically range from $40,000 to $60,000. Once disease becomes disseminated, costs can exceed $150,000 to $300,000, excluding indirect costs such as lost productivity, long-term disability, and caregiver burden.

Beyond treatment expenses, litigation related to morcellation-associated cancer spread has resulted in multi-million-dollar settlements, particularly during the power morcellation litigation wave of the mid-2010s. Several cases explicitly tied disease progression to tissue dissemination during surgery.

From a system perspective, a single preventable dissemination event can negate the cost savings of hundreds of minimally invasive procedures.

Benign Tissue Seeding: The Long Tail of Surgical Cost

Cancer is not the only concern.

Uncontained morcellation has also been associated with the spread of benign tissue, including parasitic fibroids and iatrogenic endometriosis, conditions that may present years after the index surgery.

Endometriosis alone represents one of the most expensive chronic gynecologic conditions. Multiple health economic studies estimate annual per-patient costs of $12,000 to $16,000, with lifetime costs exceeding $100,000, driven by repeat surgeries, chronic pain management, hormonal therapy, and fertility interventions.

While the financial impact may surface years later, downstream harm is increasingly traced back to the index procedure, including the choice between FDA-cleared containment and off-label alternatives used during tissue extraction.

Off-Label Use and the Quiet Accumulation of Liability

One of the least visible, but most consequential, dimensions of morcellation risk lies in off-label device use.

Many tissue bags currently used during morcellation are not FDA-cleared for prevention of tissue spillage during organ cutting and removal. While off-label use is common in medicine, it carries distinct legal and financial implications when complications occur.

Risk management guidance from MedPro Group, one of the largest medical malpractice insurers in the United States, has repeatedly warned that off-label use increases professional liability exposure in three key ways:

1. Burden of justification

When an FDA-cleared alternative exists, the legal burden shifts to the surgeon to prove that off-label use met the standard of care.

2. Informed consent vulnerability

Standard consent language may be insufficient for off-label device use, increasing exposure to failure-to-warn claims if complications arise.

3. Changed liability dynamics

Off-label use alters traditional liability dynamics, increasing scrutiny on clinical decision-making at the hospital and surgeon level.

Legal scholarship published in Clinical Orthopaedics and Related Research has echoed these concerns, noting that courts increasingly allow off-label status to be considered in malpractice cases, particularly when patient harm occurs and safer alternatives were available.

Recent U.S. court decisions have further reinforced that while off-label use is generally permitted, it is not immune from civil liability and, in rare but serious circumstances, criminal consequences when tied to demonstrable patient harm.

FDA Guidance Exists, Adoption Lags Behind

Regulatory expectations around morcellation are no longer ambiguous. The FDA has consistently called for tissue containment during tissue cutting to mitigate the risks of cancer and tissue dissemination.

Yet real-world adoption remains inconsistent.

A 2025 survey reported by News-Medical found widespread gaps in safe tissue containment during laparoscopic gynecologic surgery.

Respondents cited variability in training, institutional protocols, and access to FDA-cleared containment systems. Many surgeons reported reliance on improvised or non-cleared solutions despite growing awareness of regulatory and legal risk.

The result is a widening gap between guidance and practice, one that is increasingly visible to regulators, insurers, and hospital leadership.

Who Ultimately Pays?

The economic impact of uncontained morcellation does not fall on a single stakeholder.

• Hospitals face litigation exposure, rising malpractice premiums, re-operations, and reputational risk.
• Surgeons shoulder personal liability, heightened scrutiny around informed consent, and evolving standards of care.
• Payers absorb downstream oncology costs, chronic disease management, and repeat interventions.
• Patients bear the heaviest burden, including preventable morbidity, fertility loss, financial toxicity, and erosion of trust.

Taken together, these costs far exceed the price of prevention.

From Clinical Risk to Market Response

This growing recognition of risk has begun to reshape the market.

Before regulatory scrutiny intensified, power morcellation was widely adopted because it saved time, reduced operating room burden, and supported high procedural throughput.

It represented a multi-billion-dollar global market, supported by major surgical device manufacturers and deeply embedded in minimally invasive gynecologic practice.

The withdrawal of power morcellation from many hospitals did not eliminate the clinical need for efficient tissue extraction. Instead, it created a prolonged gap between surgical efficiency and acceptable risk.

That gap is now beginning to close.

With the emergence of FDA-cleared tissue containment systems designed specifically for morcellation, hospitals are reassessing whether power morcellation can be responsibly reintroduced in a manner aligned with regulatory guidance, patient safety, and liability mitigation.

This has significant implications for operating room efficiency, surgeon ergonomics, and system-wide cost management.

One example is Ark Surgical, a U.S.-focused surgical technology company advancing safety-first approaches to tissue extraction.

Its double-wall, airbag-like LapBox containment chamber was developed to support FDA-aligned morcellation while integrating into existing laparoscopic workflows, an increasingly important consideration as hospitals evaluate not just procedural efficiency, but long-term risk exposure.

Ark Surgical is currently in an active investment round, reflecting broader investor interest in technologies that address regulatory-driven risk while unlocking previously constrained markets.

More broadly, capital is flowing toward solutions that make it possible to restore clinical efficiency without reintroducing legacy risk.

The Cost Question Is No Longer “If,” but “When”

Healthcare systems already absorb the cost of uncontained morcellation through litigation, chronic disease management, repeat interventions, and loss of trust.

What has changed is visibility.

As clinical data, regulatory expectations, and market solutions converge, the question is no longer whether containment matters, but whether healthcare systems can afford to continue treating it as optional.

High brain oestrogen may raise women’s PTSD risk if severe stress strikes during high oestrogen phases, causing memory problems and stronger fear responses, new research has revealed.

The study found that exposure to several simultaneous stressors can lead to persistent memory problems, difficulty recalling events and stronger reactions to trauma reminders.

Tallie Baram is distinguished professor of paediatrics, anatomy and neurobiology, and neurology at UC Irvine’s School of Medicine, and led the research.

Baram said: “High oestrogen is essential for learning, memory and overall brain health.

“But when severe stress hits, the same mechanisms that normally help the brain adapt can backfire, locking in long-lasting memory problems.”

Oestrogen, which usually supports learning and memory, can increase vulnerability when levels are high in the hippocampus, a brain region central to memory formation and retrieval.

Researchers reported that female mice stressed during cycle phases with high oestrogen developed enduring memory loss and heightened fear of reminders, while lower levels were protective. Males, who also have high hippocampal oestrogen, were susceptible more mildly and through different receptor pathways.

High oestrogen loosens the packaging of DNA in brain cells, known as permissive chromatin.

This normally helps learning, but under extreme stress it can allow harmful, lasting changes in memory circuits.

Memory problems were driven by different oestrogen receptors in men and women, alpha in men and beta in women.

Blocking the relevant receptor prevented stress-related memory issues even when oestrogen stayed high. Vulnerability depended on hormone levels at the time of stress, not afterwards.

Co-author Elizabeth Heller is associate professor of pharmacology at the University of Pennsylvania Perelman School of Medicine.

She said: “A lot of what determines vulnerability is the state your brain is already in.

“If a traumatic event hits during a period when oestrogen is already unusually high, the biology can amplify the impact in lasting ways.

“This study shows that a state of high oestrogen in a specific brain region promotes vulnerability to stress in both male and female subjects.”

A study of 17,494 people has revealed a gap between perimenopause symptoms people expect and those they report, with fatigue and exhaustion far outranking hot flushes.

While 71 per cent associated perimenopause with hot flushes, those reporting perimenopause cited exhaustion (95 per cent) and fatigue (93 per cent) far more often.

Among more than 12,000 participants over age 35, the most common symptoms were fatigue (83 per cent), exhaustion (83 per cent), irritability (80 per cent), low mood (77 per cent), sleep problems (76 per cent), digestive issues (76 per cent) and anxiety (75 per cent).

Researchers at Mayo Clinic conducted the study with Flo, a women’s health application, assessing symptoms among 17,494 people from 158 countries.

First author Mary Hedges is a community internal medicine physician at Mayo Clinic in Florida.

Hedges said: “This study shines a light on how little we still understand about perimenopause and how much it affects people’s daily lives.

“At Mayo Clinic, we’re working to expand that understanding so we can improve awareness and guide care that truly meets the needs of each patient.”

The findings show fatigue, mood changes and sleep-related issues sit at the centre of many people’s experiences during perimenopause, the years leading up to the final menstrual period and the first year after it ends. This transition can start in the 30s and last several years.

When asked what they associate with perimenopause, participants most often named hot flushes (71 per cent), sleep problems (68 per cent) and weight gain (65 per cent).

The study distinguishes between exhaustion and fatigue, with exhaustion defined as a general decrease in performance, impaired memory, decreased concentration and forgetfulness, whilst fatigue refers to physical exhaustion.

Researchers noted that hormone shifts may disrupt the body’s natural rhythms and restorative sleep, while mood changes can be influenced by hormones, inflammation and diet.
