An interventional study of Robotic surgery using the Sentire Surgical System in Colorectal Carcinoma, Rectal Prolapse and Prostate Cancer (Adenocarcinoma), sponsored by Chinese University of Hong Kong. Recruiting at 1 site in China. Open to participants aged 18 Years to 80 Years. Per ClinicalTrials.gov, last updated 2025-04-16.
Sponsored by Chinese University of Hong Kong · Not applicable, Interventional, and Treatment
Robotic assisted surgery has been performed for more than two decades with good success and safety profile. However, there was only one dominating robotic surgical system available in the past which led to high cost for robotic surgery. Recently, a new robotic surgical system (Sentire Robotic Surgical System) was introduced by researchers of The Chinese University of Hong Kong (CUHK). This new robotic surgical system aims to achieve similar outcomes and standards of robotic surgery performed using the dominating system but with a significantly lower cost. The technologic innovation and development of this new robotic system is made by the Cornerstone Robotics Limited, which is based in Hong Kong. In a pilot clinical study conducted at Prince of Wales Hospital involving 55 patients, the Sentire Robotic Surgical System had demonstrated high success rate with minimal complications in patients who underwent robotic colorectal, upper gastrointestinal, and urologic surgery. Researchers of CUHK would therefore like to conduct another prospective study to further evaluate the efficacy and safety of Sentire Surgical System C1000 in major gastrointestinal and urologic surgery with expanded indications. It is believed that the results of this study will provide data to support its use for wide range of procedures with minimal access trauma, for the benefit of patients. This system will also lead to a wider range of clinical application for minimally invasive surgery with a cost-effective model.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
Neoadjuvant treatment is given before the main treatment (usually surgery), often to shrink a tumour. Adjuvant treatment is given after it, to lower the chance of the cancer coming back.

Anal continence after surgery, measured by the Cleveland Clinic Incontinence Score (Wexner's Score)
The Cleveland Clinic Incontinence Score or Wexner's Score is the most common score used to determine the severity of incontinence before and after surgery for anal incontinence. The scoring system takes into account the type and frequency of incontinence, and the extent to which it alters the patient's life. It consists of five questions to assess the degree of incontinence (solid, liquid, gas, wears pad, lifestyle alteration). The frequency of each type of incontinence is rated on a scale ranging from 0 (never) to 4 (always or to once a day) so that the sum of the frequencies add up to a total score that may range from 0 to 20. Higher scores indicate higher levels of incontinence.
Time frame: Up to 12 months
Male sexual function after surgery, measured by the International Index of Erectile Dysfunction - 5 (IIEF-5 questionnaire)
IIEF-5 is an abridged five-item version of the 15-item International Index of Erectile Function (IIEF) which is used to diagnose the presence and severity of erectile dysfunction. This questionnaire consists of only five questions and each IIEF-5 item is scored on a five-point ordinal scale where lower values represent poorer sexual function. Thus, a response of 0 for a question is considered the least functional, whereas a response of 5 is considered the most functional. The possible scores for the IIEF-5 range from 1 to 25 (one question has scores of 1-5), and a score above 21 is considered as normal erectile function and at or below this cutoff, erectile dysfunction.
Time frame: Up to 12 months
Urinary function after surgery, measured by the International Prostate Symptom Score (IPSS)
IPSS is based on the answers to seven questions concerning urinary symptoms and one question concerning quality of life. Each question concerning urinary symptoms allows the patient to choose one out of six answers indicating increasing severity of the particular symptom. The answers are assigned points from 0 to 5. The total score can therefore range from 0 to 35 (asymptomatic to very symptomatic).
Time frame: Up to 12 months
