What researchers measure

Primary outcomes

  1. Complete (R0) resection

    rate of complete (R0) resection defined as en bloc, one-piece resection with histologically confirmed tumour-free lateral and vertical margins

    Time frame: 30 days

Secondary outcomes

  1. Bleeding during or after the procedure

    Bleeding as evidence by 1. Active bleeding during the robotic ESD procedure 2. Bleeding after ESD with clinical evidence of 1. Fresh hematemesis; 2. Passage of tarry stool with pulse \> 100 or systolic blood pressure \< 100; 3. Drop in hemoglobin level of \> 4 g/dl

    Time frame: 30 days

  2. Perforation

    Perforation at the ESD site as assessed by endoscopy

    Time frame: 30 days

  3. Adjunctive procedures to control bleeding

    Use of coagrapser / clips

    Time frame: 1 day

  4. All cause mortality

    Mortality

    Time frame: 30 days

  5. Infection

    Clinical sepsis with changes in inflammatory markers as evidence by 1. clinical symptoms of fever, pulse \> 100 2. radiological evidence of intraperitoneal collection 3. elevated WBC count of \> 10.0

    Time frame: 30 days

  6. Impairment of renal function

    renal failure as evidence of derangement of renal function with elevated creatinin level \> 100 mmol/l

    Time frame: 30 days

  7. Serious Adverse Events

    Serous Adverse Events at preocedure and through discharge

    Time frame: 30 days

  8. Duration of procedure

    OT time

    Time frame: 1 day

  9. Operator assessment of device performance

    Operator assessment

    Time frame: 1 day

  10. Device deficiencies

    Device malfunction and Use errors during the ESD procedure as evidence by 1. cessation of the function of the EndoMASTER EASE system 2. need to use of the immediate cessation button for the EndoMASTER EASE system

    Time frame: 1 day

  11. Length of Hospital stay

    Length of Hospital Stay

    Time frame: 30 days

  12. Histology of resected specimen

    En bloc resection rate / R0 rate / positive vertical margin / positive lateral margin

    Time frame: 30 days

  13. Colonoscopy followup

    Healing of operative site / presence of suspicious tissue for biopsy / presence of stricture

    Time frame: 6 months, 18 months to 3 years

  14. Cancer status by cross-sectional imaging (MRI / CT)

    local recurrence / recurrence at different site in colon / metastatic disease and location

    Time frame: 12 months and 3 years

  15. Technical Success

    en bloc, one-piece excision of the neoplasm irrespective of histopathology, in the absence of device-related SAE through 30 days

    Time frame: 30 days
