Guidance for Industry and 
Food and Drug Administration Staff 
This guidance represents the current thinking of the Food and Drug Administration (FDA or 
Agency) on this topic. It does not establish any rights for any person and is not binding on 
FDA or the public. You can use an alternative approach if it satisfies the requirements of the 
applicable statutes and regulations. To discuss an alternative approach, contact the FDA staff 
or Office responsible for this guidance as listed on the title page. 
I.  Introduction 
This guidance contains recommendations concerning the content and format for certain labeling 
information for laparoscopic power morcellators (LPMs).1 The recommendations in this 
guidance reflect the state of the science and available technology regarding use of LPMs and are 
being made in light of scientific information that suggests that the use of these devices 
contributes to the dissemination and upstaging2 of an occult uterine malignancy in women 
undergoing laparoscopic gynecologic surgery for presumed fibroids. FDA is also recommending 
that manufacturers incorporate into the labeling for these devices information providing greater 
specificity regarding the risk of use as it relates to age, information regarding the risk of 
spreading malignant and benign uterine tissue, and information regarding the use of LPM 
containment systems. These labeling recommendations are intended to enhance, but not replace, 
the physician-patient discussion of the benefits and risks of use of LPMs that uniquely pertain to 
individual patients. FDA believes this effort will promote the safe and effective use of LPMs 
when used for gynecologic surgeries. 
FDAs guidance documents, including this guidance, do not establish legally enforceable 
responsibilities. Instead, guidances describe the Agencys current thinking on a topic and should 
be viewed only as recommendations, unless specific regulatory or statutory requirements are 
cited. The use of the word should in Agency guidance means that something is suggested or 
recommended, but not required. 
                                                
1 This guidance uses the term laparoscopic power morcellators or LPMs in lieu of laparoscopic electromechanical 
morcellators. FDA believes this terminology is understood and recognized both by clinicians and non-clinicians (e.g., American 
College of Obstetricians and Gynecologists Special Report: Power Morcellation and Occult Malignancy in Gynecologic Surgery 
May 2014, available at: https://www.sgo.org/wp-content/uploads/2014/04/ACOG_Statement.pdf and Society of Gynecologic 
Oncology Position Statement: Morcellation December 2013, available at: https://www.sgo.org/resources/morcellation/). 
2 A cancers stage is a reflection of the extent and/or severity of the disease and helps in determining the prognosis and 
appropriate treatment options. Upstaging refers to an increase in the extent or severity of the disease in a given patient, in this 
case due to the iatrogenic spread and growth of tumor within the peritoneal cavity.

II.  Background 
As the number of laparoscopic and minimally invasive procedures has increased with the 
introduction of new surgical technologies and techniques, additional safety information has 
become available regarding the use of LPMs. Discussions within the patient and clinical 
communities, as well as the peer-reviewed medical literature, have raised awareness of the risk 
of spreading unsuspected cancerous tissue beyond the uterus when LPMs are used during 
gynecologic surgeries intended to treat benign fibroids. Numerous case reports and case series 
have been published, and FDA has received Medical Device Reports (MDRs) that describe the 
iatrogenic dissemination, implantation, and subsequent growth of unsuspected neoplastic tissue 
within the peritoneal cavity following laparoscopic morcellation of uterine tissue believed to 
contain fibroids based on pre-operative diagnosis.3, 4, 5 In 2014, FDA presented an analysis of 
available information suggesting that the risk of an occult uterine sarcoma in a woman 
undergoing surgical intervention for presumed fibroids is substantially higher than had 
previously been assumed or reported.5, 6, 7, 8, 9, 10, 11, 12, 13, 14 FDAs analysis also suggested that

patient outcomes, including survival, may be significantly adversely impacted from this 
upstaging of disease.3, 5, 15, 16, 17, 18
Patient selection and choice of surgical technique can reduce the risk of spreading cancer. While 
unsuspected cancer can occur at any age, the prevalence of unsuspected cancer in women 
undergoing hysterectomy for fibroids increases with age such that the benefit-risk profile of 
using LPMs is worse in older women when compared to younger women.19, 20 Also, the surgical 
technique of en bloc tissue removal eliminates the need to perform morcellation, thereby 
reducing the risk of iatrogenic dissemination and upstaging of an occult sarcoma. A thorough 
pre-operative screening should be conducted; however, it is important to note that no screening 
procedure that can reliably detect sarcoma preoperatively has been identified. As part of shared 
decision-making, physicians should discuss the risks and benefits of all relevant treatment 
options with their patients prior to undergoing the procedure. 
FDA considered the scientific information outlined above to represent a significant change to the 
benefit-risk profile for these devices, prompting the issuance of a Safety Communication on 
April 17, 201421 and the convening of the FDAs Obstetrics and Gynecology Devices Panel of 
the Medical Devices Advisory Committee22 on July 10-11, 201423 to further discuss the use and 
labeling of LPMs during gynecologic surgeries. FDA issued an immediately in effect guidance 
document after considering the input of the Panel and other stakeholders, including comments 
made during the Open Public Hearing portion of the Panel meeting. 
Following issuance of the 2014 guidance document, FDA continued to consider new scientific 
information and the input of stakeholders. FDA provided an updated analysis in 201724
considering new information that became available since the first analysis was performed. The 
publications referenced in the updated analysis continue to provide evidence for differences in

patient outcomes between groups, including among groups exposed to power morcellation, non-
powered morcellation or no morcellation. Further, additional scientific information is available 
that stratifies the risks of an undetected uterine cancer in women with presumed fibroids based 
on age.25, 26, 27, 28, 29, 30
FDA also considered scientific information pertaining to the risk of spreading benign uterine 
tissue beyond the uterus during gynecologic surgeries when LPMs are used.31, 32, 33 Parasitic 
myomas and disseminated peritoneal leiomyomatosis, while benign, have been associated with 
the need for additional surgery due to symptoms such as abdominal pain and distension. It is 
important to note that a containment system cannot prevent all cases of benign tissue spread 
during such procedures as some cases may occur spontaneously without morcellation. 
Finally, FDA considered additional available mitigations for the spread of uterine tissue. Since 
2014, FDA has provided marketing authorization for LPM containment systems intended to 
isolate and contain tissue that is considered benign. These products have been shown, through 
bench testing and simulated use testing, to contain such tissue during morcellation.34 A 
containment system, however, cannot prevent against the potential spread of cancer that might 
result from: 
  Tissue that spreads due to manipulation of the tissue before it is placed into the tissue 
containment system; or 
  Cancer that may have already spread through the blood, lymphatic system or fallopian 
tubes (transtubal transport) before the surgical procedure. 
For these reasons, FDA is updating its recommendations, as originally described in the 2014 
guidance document, concerning the content and format of certain labeling information for LPMs. 
Specifically, FDA is recommending that manufacturers incorporate into the labeling for these 
devices information providing greater specificity regarding the risk of use as it relates to age, 
information regarding the risk of spreading benign uterine tissue, and information regarding the 
use of LPM containment systems.

III.  Scope 
This guidance provides recommendations concerning the content and format of certain labeling 
information for LPMs used for gynecologic surgeries. LPMs may include general indications for 
use (e.g., laparoscopic procedures) or specific indications for use (e.g., laparoscopic gynecologic 
procedures). This guidance applies to LPMs with either a general indication or a specific 
gynecologic indication, as either may be used in gynecologic laparoscopic procedures. This 
guidance applies to LPMs regardless of morcellation mechanism (e.g., electromechanical, 
radiofrequency). 
This guidance does not apply to LPMs specifically indicated only for non-gynecologic surgery. It 
also does not apply to hysteroscopic morcellators, which have a different principle of operation. 
FDA believes that, when used in accordance with current indications and instructions for use, 
hysteroscopic morcellators do not pose the same risk as the devices addressed in this guidance 
because any sarcomatous tissue present does not enter the peritoneal cavity. 
This guidance is not intended to include a complete listing of all labeling components for LPMs 
used for gynecologic surgery. Rather, this guidance contains recommendations regarding the 
inclusion of certain information in LPM labeling that FDA believes is important to the safe and 
effective use of LPMs in gynecologic surgery. Accurate product labeling for LPMs and effective 
communication of that labeling are important to help ensure that physicians and patients are 
aware of the risks associated with the use of LPMs in gynecologic surgery, including the 
dissemination of malignant tissue and potential clinical outcomes associated with the 
laparoscopic morcellation of occult uterine malignancy. FDA believes that the physician and 
patient information discussed in this guidance should be included in labeling under sections 
502(a), 201(n), and 502(f)(2) of the Federal Food, Drug, and Cosmetic Act (FD&C Act). FDA 
recommends that manufacturers implement the labeling recommendations discussed herein35 and 
follow them in labeling submitted with future 510(k) submissions. 
IV.  Labeling Components 
FDA recommends that the labeling of LPMs with a general indication or a specific gynecologic 
indication include a boxed warning, contraindications, and warnings regarding the risk of use as 
it relates to age, spreading malignant and benign uterine tissue, and the use of LPM containment 
systems. This section contains FDAs format and content recommendations for these 
components, and to help illustrate, FDA has provided examples in each subsection. 
A.  Boxed Warning 
FDA believes that a boxed warning should be part of the labeling materials for LPMs. In general, 
boxed warnings are noticeable and easy to read and understand, and FDA believes a boxed 
warning would be particularly useful in communicating the risks that have been identified in the 
                                                
35 A manufacturer with an existing 510(k) clearance should: 1) add the information to their labeling; 2) submit both the current 
labeling and revised labeling to CDRH; and 3) provide updated labeling to purchasers for LPMs that have already been 
distributed. In addition, FDA does not intend to object if such labeling changes are submitted as an add-to-file to the existing 
510(k) rather than as a new 510(k). 
5 Contains Nonbinding Recommendations 
scientific information discussed above. FDA therefore recommends that a boxed warning 
generally inform physicians, and recommend that physicians share with patients, that: 
  Uterine tissue may contain unsuspected cancer; and 
  The use of LPM during fibroid surgery may spread cancer and decrease the long-term 
survival rate of patients. 
An example of a boxed warning that follows this recommendation is below. 
WARNING:  Uterine  tissue  may  contain  unsuspected  cancer.  The  use  of 
laparoscopic power morcellators during fibroid surgery may spread cancer 
and decrease the long-term survival of patients. This information should be 
shared with patients when considering surgery with the use of these devices. 
B.  Contraindications and Other Warnings 
In addition to the boxed warning, FDA also believes that the labeling of LPMs should include 
contraindications and warnings highlighting certain key information regarding the risks of use of 
LPMs in gynecologic surgeries. We recommend the labeling for LPMs generally inform 
physicians, and recommend that physicians share with patients, that: 
  LPMs are contraindicated in gynecologic surgery in which the tissue to be 
morcellated is known or suspected to contain malignancy; 
  LPMs are contraindicated for removal of uterine tissue containing suspected fibroids 
in patients who are post-menopausal or over 50 years of age, or candidates for en bloc 
tissue removal through the vagina or via a mini-laparotomy incision; 
  The risk of occult cancer, including uterine sarcoma, increases with age, particularly 
in women over 50 years of age; 
  Uncontained power morcellation has been associated with the spread of benign 
uterine tissue, i.e., parasitic myomas and disseminated peritoneal leiomyomatosis, 
potentially requiring additional surgeries; and 
  LPMs should only be used with a containment system. The containment system 
should be compatible with the LPM. 
Examples of labeling statements that follow these recommendations are below. 
CONTRAINDICATION: Laparoscopic power morcellators are contraindicated in 
gynecologic surgery in which the tissue to be morcellated is known or suspected to 
contain malignancy. 
CONTRAINDICATION: Laparoscopic power morcellators are contraindicated for 
removal of uterine tissue containing suspected fibroids in patients who are: 
  post-menopausal or over 50 years of age, or 
  candidates for en bloc tissue removal through the vagina or via a mini-laparotomy 
incision. 
WARNING: The risk of occult cancer, including uterine sarcoma, increases with age, 
6 Contains Nonbinding Recommendations 
particularly in women over 50 years of age. This information should be shared with 
patients when considering surgery with the use of these devices. 
WARNING: Uncontained power morcellation has been associated with the spread of 
benign uterine tissue, i.e., parasitic myomas and disseminated peritoneal 
leiomyomatosis, potentially requiring additional surgeries. 
WARNING: Laparoscopic power morcellators should only be used with a containment 
system. The containment system should be compatible with the laparoscopic power 
morcellator.
