One year follow-up of the colon cancer patient cohort treated with a novel miniaturized robotic-assisted surgery device (mRASD).

Background: With the proven benefits of minimally invasive surgery, there is steady growth in robotic surgery use and interest in novel robotic platforms. A miniaturized Robotic-Assisted Surgery Device (mRASD) has been in clinical use under a multi-center, investigational device exemption (IDE) study for right and left colectomy. The goal of this work was to report the short-term and 12-month outcomes specifically for the cohort of colon cancer patients that underwent surgery using the mRASD.

Comparing advanced platforms for local excision of rectal lesions.

Background: Transanal surgery facilitates organ preservation in select patients with benign and early malignant rectal lesions to avoid the functional consequences of radical surgery. The transanal endoscopic microsurgery (TEM) platform created a standard for local excision with lower margin positivity and recurrence rates than traditional transanal excision. The single-port robot (SP r) presents a promising alternative transanal platform.

Safety and Efficacy of a Novel Miniaturized Robotic-Assisted Surgery System in Colectomy: A Prospective, Investigational Device Exemption Clinical Study Using the IDEAL Framework.

Background: Robotics has increased rates of minimally invasive surgery, with distinct advantages over open surgery. However, current commercially available robotic platforms have device and system issues that limit robotic-assisted surgery expansion.

Objective: To demonstrate the safety and efficacy of a novel miniaturized robotic-assisted surgery device in colectomy.

Perioperative outcomes for single-port robotic versus single-incision laparoscopic surgery: a comparative analysis in colorectal cancer surgery.

Background: Single-incision laparoscopic surgery (SILS) may offer improved cosmesis, reduced postoperative pain and faster recovery than conventional platforms, but widespread implementation was limited by technical demands. A single-port robotic platform was recently introduced, with components that further enhance SILS benefits without the technical challenges. No study to date has compared the two platforms to validate benefits.

Longitudinal Analysis of Local Recurrence and Survival After Transanal Abdominal Transanal Radical Proctosigmoidectomy for Low Rectal Cancer Treated With Neoadjuvant Chemoradiation Therapy.

Background: The transanal abdominal transanal radical proctosigmoidectomy was developed in 1984 as a sphincter preservation surgery in patients with low rectal cancers after preoperative radiation therapy. While serving as a catalyst for disruptive sphincter preservation surgery, it continues to be used and evolve. With the controversy over safety and local recurrence in other sphincter-preserving surgery, review of transanal abdominal transanal radical proctosigmoidectomy long-term oncologic outcomes is warranted.
