About this study

Official title: Endoscopic Submucosal Dissection (ESD) Versus Transanal Minimally Invasive Surgery (TAMIS) for Early Rectal Neoplasms: a Prospective Randomized Controlled Trial

This is a prospective randomized controlled trial that aimed to compare the short-term clinical outcomes, functional outcomes, costs, and recurrence rates between endoscopic submucosal dissection (ESD) and transanal minimally invasive surgery (TAMIS) for early rectal neoplasms.

Read the detailed description

Background: Transanal minimally invasive surgery (TAMIS) is an effective surgical alternative to transanal excision for treating early rectal neoplasms not amenable to en bloc resection by conventional colonoscopic techniques. Endoscopic submucosal dissection (ESD) is a revolutionary endoscopic procedure that enables en bloc resection of large rectal neoplasms with low morbidity. To date, no randomized controlled trial can be found in the literature comparing the two modalities.

Objectives: To compare the short-term clinical outcomes, functional outcomes, costs, and recurrence rates between ESD and TAMIS for early rectal neoplasms.

Design: Prospective randomized controlled trial.

Subjects: One hundred and fourteen consecutive patients diagnosed with early rectal neoplasms (>/=2 cm in size and without evidence of deep submucosal invasion) that are not amenable to en bloc resection by conventional colonoscopic techniques will be recruited.

Interventions: Patients will be randomly allocated to receive either ESD or TAMIS.

Outcome measures: Primary outcome: 30-day morbidity/mortality defined by the Clavien-Dindo classification. Secondary outcomes: hospital stay, functional outcomes and quality of life, overall costs, R0 resection rate, and recurrence rate.

Conclusions: Results of the present study can provide evidence-based clarification of the efficacy and safety of ESD in treating early rectal neoplasms. The Investigators hypothesize that ESD is associated with lower morbidity, shorter hospital stay, and similar R0 resection rate when compared with TAMIS. A faster recovery and earlier discharge after ESD may reduce financial burden to the hospital/healthcare system. The results of this proposed project may have a significant impact on the future treatment strategy for early rectal neoplasms.

Study groups in NCT03217773
Study groupRoleWhat they receive
ESDExperimentalESD is an endoscopic procedure that enables en bloc resection of large tumors in the gastrointestinal tract, irrespective of the size of the lesion. ESD uses an electrosurgical cutting device to purposely dissect the deeper layers of the submucosa to remove neoplastic mucosal lesions in a single piece.
Receives: Procedure: ESD
TAMISActive comparatorTAMIS is a minimally invasive means of removing large rectal neoplastic lesions not accessible by conventional transanal excision. It is performed using the GelPOINT path transanal access platform and laparoscopic instruments.
Receives: Procedure: TAMIS

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Short-term morbidity

    Short-term morbidity/mortality within 30 days after the procedure (including intraprocedural morbidity/mortality), defined by the Clavien-Dindo classification of surgical complications

    Measured: Up to 1 month

Secondary outcomes (10)
  1. En bloc resection rate

    Resection with a single piece

    Measured: Up to 1 month

  2. R0 resection rate

    Complete resection of the neoplasm with clear lateral and deep margins at histology

    Measured: Up to 1 month

  3. Time to resume normal diet

    Measured: Up to 1 month

  4. Time to walk independently

    Measured: Up to 1 month

  5. Length of hospital stay

    Measured: Up to 1 month

  6. Anal continence

    Measured by the Wexner's score

    Measured: Up to 1 year

  7. Fecal incontinence quality of life (FIQL)

    Measured by the FIQL questionnaire

    Measured: Up to 1 year

  8. Quality of life measured by the Short Form-36 (SF-36) Health Survey questionnaire

    SF-36 Health Survey is a 36-item, patient-reported survey of patient health. It consists of eight scaled scores, which are the weighted sums of the questions in their section. The eight sections are: vitality, physical functioning, bodily pain, general health perceptions, physical role functioning, emotional role functioning, social role functioning, and mental health. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The lower the score the more disability. The higher the score the less disability i.e., a score of zero is equivalent to maximum disability and a score of 100 is equivalent to no disability.

    Measured: Up to 1 year

  9. Direct medical costs

    Measured: Up to 1 year

  10. Local recurrence

    Measured: Up to 3 years

Questions about this trial

What is this clinical trial studying?

A study testing ESD and TAMIS in people with Rectal Neoplasms, run by Chinese University of Hong Kong at 1 site in Hong Kong.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 17 Sep 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Hong Kong. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Simon SM Ng, MD (3505 1495, simonng@surgery.cuhk.edu.hk), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Short-term morbidity (time frame: Up to 1 month). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Sep 2019.
