ESD Versus TAMIS for Early Rectal Neoplasms

Status Recruiting

Clinical Trial Summary

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.

Clinical Trial 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. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
