Official title: Evaluation of SINGLE PORT (SP) Robotic Technology in Colorectal Surgery

Run by University of California, Davis · NCT05321134 · Data updated 2026-11-12

This study is testing a new single port robotic surgery method for colorectal procedures to see if it's safer and works better than the traditional multi-port approach.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 and older with colorectal conditions such as colorectal cancer, rectal prolapse, or colostomy stoma.

Probably not a fit

Patients who are not eligible due to age restrictions, pregnancy, or those with contraindications to robotic surgery may not benefit from this study.

What this trial studies

This study investigates the use of a Single Port (SP) Robotic Platform for colorectal surgeries, comparing its safety and effectiveness to the traditional Multi-port (Xi) Robotic Platform. It is a single center, prospective, open-label, investigator-initiated, non-randomized case-control study. Researchers will assess perioperative outcomes from surgeries performed with the SP platform and evaluate the feasibility and quality of these procedures. The aim is to determine if the SP platform can provide a viable alternative for colorectal surgical indications.

Why it matters

Potential benefit: If successful, this approach could lead to less invasive surgical options for patients with colorectal conditions, potentially improving recovery times and outcomes.

How similar studies have gone: While the SP platform has been FDA approved for other surgical fields, its application in colorectal surgery is novel and has not been widely tested.

Inclusion Criteria:

* The subject is male or female, greater than or equal to 18 years of age. If female, the subject has a negative urine pregnancy test and is not lactating, or has not been of childbearing potential for at least 3 months prior to use of study product. To be considered to be not of childbearing potential, the subject must be postmenopausal for at least 2 years; have had a hysterectomy or bilateral tubal ligation, or be proven to be otherwise incapable of pregnancy. If of childbearing potential, the subject must have been practicing one of the following methods of contraception consistently for at least 1 month prior to study entry and agree to continue practicing it during the study: hormonal contraceptives, intrauterine device, spermicide and barrier, spouse/partner sterility; or is practicing abstinence and agrees to continue abstinence or to start an acceptable method of contraception from the above list if sexual activity commences.
* There is documentation of a colorectal diagnosis requiring operative interventions with clinical plans for a robotic operation.
* For robotic transanal procedures, patients who would meet standard guidelines for a transanal procedures (T1N0 rectal adenocarcinoma, Precancerous adenomas, and localized neuroendocrine tumors) distal to 15 cm from the anal verge.
