NCT03217773

Brief 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.

    Up to 1 month

Secondary Outcomes (10)

  • En bloc resection rate

    Up to 1 month

  • R0 resection rate

    Up to 1 month

  • Time to resume normal diet

    Up to 1 month

  • Time to walk independently

    Up to 1 month

  • Length of hospital stay

    Up to 1 month

  • +5 more secondary outcomes

Study Arms (2)

ESD

EXPERIMENTAL

ESD 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.

Procedure: ESD

TAMIS

ACTIVE COMPARATOR

TAMIS 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.

Procedure: TAMIS

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients diagnosed with nonpedunculated early rectal neoplasms \>/= 2 cm in size in the rectum (\>/= 3 cm and \</= 18 cm from the anal verge) that are deemed not feasible for en bloc resection with conventional polypectomy or EMR as judged by two experienced endoscopist
  • Age of patients \>18 years;
  • American Society of Anesthesiologists (ASA) grading I-III
  • Informed consent available

You may not qualify if:

  • Presence of endoscopic signs of massive submucosal invasion (including excavated/depressed morphology, Kudo's pit pattern Type V, or Sano's capillary pattern Type IIIB)
  • Evidence of deep invasion on endorectal ultrasonography
  • Unfavorable histopathologic features on biopsy (mucinous cancer, poor differentiation, or gross submucosal invasion)
  • Patients with other synchronous colorectal neoplasms in addition to the index neoplasm that are indicated for surgical resection
  • Patients with recurrence from previous Endoscopic Mucosal Resection or ESD
  • Patients with known metastatic disease
  • Patients with non-correctable coagulopathy
