Official title

A Pilot Study of Single-port Robot-assisted Surgery Using da Vinci SP Surgical System for the Surgical Treatment for Patients With Obstructive Sleep Apnea

Overview

This prospective, interventional, non-randomized, single arm, clinical trial will investigate feasibility and safety of trans-oral robotic surgery using da Vinci SP Surgical System in Taiwan for the surgical treatment of OSA. All the investigators are well trained and have received proof of training after completing the training program for da Vinci SP system provided by Intuitive.

Detailed description

This study will be conducted in Chang Gung Memorial Hospital at Linkou.

Informed consent will be provided to patient who has an indication of surgical treatment for OSA. Study participants will sign an informed consent before any study procedure begins. Eligibilities will be assessed during screening period (2 weeks) with blood test and other routine assessments. Eligible patient will undergo surgical intervention using da Vinci SP Surgical System. Post-operation follow-up will be performed at 1 week, 1 month, 3 months, and 6 months.

Interventions

  • Device Da Vinci SP Surgical System, Model SP1098
    The da Vinci SP Surgical System is intended to assist in the accurate control of the da Vinci SP endoscope and instruments during minimally invasive endoscopic abdominopelvic, thoracoscopic, transoral otolaryngology, and breast surgical procedures. The system is indicated for adult use. It is intended to be used by trained physicians in an operating room environment.

Primary outcome measures

  • Conversion rate [Time frame: 3 months (+60 days) post-surgery]
  • Apena Hypopnea Index [Time frame: 3 months (+60 days) post-surgery]
Secondary outcome measures (12)
  • Multi-level surgery [Time frame: Intraoperative]
  • Snoring Scale [Time frame: 3 months (+60 days) post-surgery]
  • Operative time [Time frame: Intraoperative]
  • Console time [Time frame: 3 months (+60 days) post-surgery]
  • Transfusion and estimated blood loss [Time frame: 3 months (+60 days) post-surgery]
  • Length of hospital stay [Time frame: 3 months (+60 days) post-surgery]
  • Complication rate [Time frame: 30 days]
  • Readmission rate [Time frame: 30 days]
  • Reoperation rate [Time frame: 30 days]
  • Perioperative mortality [Time frame: 30 days]
  • Volume of resected tissue [Time frame: 3 months (+60 days) post-surgery]
  • Pain score [Time frame: 3 months (+60 days) post-surgery]

Eligibility criteria

Inclusion criteria

  • ASA physical status classification 1-2 and adequate organ function
  • Patients willing and able to comply with study protocol requirements and follow-up
  • Informed consent

Exclusion criteria

  • Prior head-and-neck surgery (note: prior invasive therapy for OSA allowed)
  • Other medical condition or anatomical factor not suitable for TORS, including subject with congenital malformations in the larynx, throat or tongue; 1. Subject with an American Society of Anesthesiologists (ASA) score of Grade 4 or above during preoperative evaluation
  • Active infectious disease
  • Can't follow trial-required procedures
  • Severe concomitant illness that drastically shortens life expectancy or increases risk of therapeutic interventions
  • Severe heart disease (NYHA functional class III-IV)
  • Severe lung disease (GOLD Group C-D)
  • Long-term use of anti-coagulant
  • Patients with coagulopathy
  • Emergency surgery
  • Subject for whom any additional surgeries are planned for OSA within the study period, after the surgery in which the da Vinci SP System was used
  • Subject is pregnant or suspected to be pregnant
