CONSTELAR is a prospective, single-arm, multi-specialty registry designed to evaluate the safety and intraoperative performance of the RonovoTM robotic surgical platform in adult patients undergoing elective oncological surgery. The study enrolls patients across four surgical specialties (Digestive Surgery, Thoracic Surgery, Urology, and Gynecology) at a single academic center. Primary endpoints include 30-day and 90-day complication rates (Clavien-Dindo classification), operative times, conversion rates, estimated blood loss, and device-related technical failures. Secondary endpoints encompass length of hospital stay, Intensive Care Unit (ICU) admission, readmission/reoperation rates, and oncological surgical outcomes (resection margins, lymph node harvest). The study aims to provide initial safety and feasibility data to support the regulatory pathway for the RonovoTM platform in Latin America.

The RonovoTM is a novel robotic surgical platform developed for minimally invasive surgery. CONSTELAR is designed as a first-in-clinical-use registry to systematically collect safety, technical performance, and short-term clinical outcome data. Eligible participants are adults (≥18 years) with confirmed malignancy diagnoses scheduled for elective robotic surgery using the RonovoTM system. Exclusion criteria include formal contraindications to minimally invasive surgery, severe prohibitive comorbidities, refusal to consent, or emergency surgery. Data collection spans from preoperative screening through 90-day follow-up, capturing demographics, comorbidities, oncological staging (Tumor, Node, Metastasis - TNM staging system 8th edition ), operative details (docking, console, and anesthesia times), intraoperative events, postoperative complications, adverse events, device technical failures, and oncological surgical outcomes. Adverse events are classified using Common Terminology Criteria for Adverse Events (CTCAE) v5.0 and causality assessment relative to the RonovoTM device. The study follows Brazilian Health Regulatory Agency (ANVISA) Collegiate Board Resolution (RDC) 837/2023 regulatory requirements

Inclusion Criteria:

1. Age ≥ 18 years
2. Confirmed malignancy diagnosis
3. Elective indication for robotic approach using RonovoTM
4. Able to understand and sign informed consent

Exclusion Criteria:

1. Formal contraindication to minimally invasive surgery
2. Severe comorbidity prohibiting the procedure
3. Refusal to participate or sign informed consent
4. Emergency surgery

It has been decided not to share Individual Participant Data (IPD) related to the study for several reasons.Protecting the privacy of participants is a priority. Sharing IPD may expose sensitive information that, even when de-identified, can be traced back to individuals.

Furthermore, the complexity of the data makes sharing challenging without the risk of misunderstandings or misinterpretations, which could compromise the integrity of the research. Sharing IPD without the explicit consent of participants may violate ethical principles of respect and protection.

There is also a need to comply with regulatory guidelines governing data sharing to avoid potential legal issues. Finally, the focus will be on disseminating aggregated results that can benefit the scientific community and the public without compromising individual privacy.
