About this study

Official title: A Novel Robotic System for Single Port and Natural Orifice Transluminal Endoscopic Surgery: A Prospective, Single Center, Multispecialty Study

This is a prospective, single center, multispecialty study that aimed to evaluate the clinical feasibility and safety of single port surgery and NOTES (mainly transanal and transoral surgery) using a novel single port robotic system.

Read the detailed description

Background: Single port surgery and natural orifice transluminal endoscopic surgery (NOTES) are emerging minimally invasive surgery techniques which can further reduce patient trauma and enhance recovery. However, the wider adoption of these techniques is hampered by the limitation of instrumentation and technical difficulties. Robotic assistance may improve surgical capabilities during single port surgery and NOTES by providing augmented motion precision and manipulation dexterity.

Objectives: To evaluate the clinical feasibility and safety of single port surgery and NOTES (mainly transanal and transoral surgery) using a novel single port robotic system.

Design: Prospective, single center, multispecialty study consistent with a stage 1 (Innovation) study described in the Innovation, Development, Exploration, Assessment, Long-term Study (IDEAL) framework.

Subjects: Sixty consecutive patients with various benign/malignant pathologies indicated for single port colorectal/urologic surgery or transanal/transoral surgery who fulfilled all the inclusion and exclusion criteria will be recruited.

Intervention: Single port surgery and transanal/transoral surgery will be performed using the novel single port robotic system.

Study Endpoints: Primary: conversion rate and perioperative complications. Secondary: operative time, blood loss, pain scores, analgesic requirement, and length of stay.

Hypothesis: The prospective study will provide important information on the feasibility, safety, and effectiveness of the novel single port robotic system in performing single port surgery and NOTES in various surgical specialties. A positive study will provide supporting evidence for continuing development of this new technology.

What is being measured

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

    An emergent change in the treatment plan to conventional minimally invasive (laparoscopic/endoscopic) surgery (i.e. the use of more than one additional port), multiport robotic surgery, or to open surgery

    Measured: Up to 1 month

  2. Perioperative complications

    Complications including intraoperative complications and all complications occurring during the hospital stay or within 30 days after discharge will be graded according to the Clavien-Dindo classification

    Measured: Up to 1 month

Secondary outcomes (15)
  1. Operative time

    Measured: Intraoperative

  2. Estimated blood loss

    Measured: Up to 1 month

  3. Pain scores on a visual analog scale

    Measured: Up to 1 month

  4. Analgesic requirement

    Measured: Up to 1 month

  5. Length of hospital stay

    Measured: Up to 1 month

  6. Completeness of resection

    Pathologic examination of the resected specimen for completeness of resection

    Measured: Up to 1 month

  7. Resection margins

    Pathologic examination of the resected specimen for resection margins positivity

    Measured: Up to 1 month

  8. Number of lymph nodes harvested

    Pathologic examination of the resected specimen (malignant cases)

    Measured: Up to 1 month

  9. Anal continence after transanal surgery

    After transanal surgery; using the Cleveland Clinic Incontinence Score (Wexner's Score)

    Measured: Up to 1 year

  10. Fecal incontinence quality of life after transanal surgery

    After transanal surgery; using the validated Chinese version of the Fecal Incontinence Quality of Life Scale (FIQL)

    Measured: Up to 1 year

  11. Urinary continence after radical prostatectomy

    After radical prostatectomy; assessed by recording the number of pads used per day

    Measured: Up to 1 year

  12. Male sexual function after radical prostatectomy

    After radical prostatectomy; using the abridged version of the International Index of Erectile Dysfunction - erectile function domain score (IIEF-EF)

    Measured: Up to 1 year

  13. Renal function after nephrectomy

    After nephrectomy; using renal function blood tests for urea and creatinine

    Measured: Up to 1 year

  14. Swallowing function after transoral robotic surgery (TORS)

    After TORS; using the MD Anderson Dysphagia Inventory

    Measured: Up to 1 year

  15. Voice function after TORS

    After TORS; using the Voice Handicap Index (VHI) 30

    Measured: Up to 1 year
