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.

A prospective phase II clinical trial/IDEAL Stage 2a series of single-port robotic colorectal surgery for abdominal and transanal cases.

Aim: Slow laparoscopy adoption accelerated the uptake of robotic surgery. However, the current robotic platforms have limitations in transanal applications and multiple port sites. The da Vinci single-port (SP) robot is currently used on trial for colorectal surgery, and broad assessment of outcomes is needed.

Initial clinical experience with Single-Port robotic (SP r) left colectomy using the SP surgical system: description of the technique.

Background: The daVinci Single-Port (SP) robot is a new robotic platform designed to overcome the challenges of Single-Incision Laparoscopic Surgery. The objective of this study is to demonstrate the feasibility and technical aspects of SP robotic (SP r) left colectomy using the SP platform.

Methods: Under Institutional Review Board approval and registration on ClinicalTrials.

Toxic megacolon during pregnancy in ulcerative colitis: A case report.

Introduction: Ulcerative colitis is an idiopathic inflammatory bowel condition whose peak incidence coincides with fertility in female patients. In pregnancy, acute fulminant colitis is rare, and, when it becomes refractory to maximum medical therapy, emergency colectomy is mandated. Over the past quarter century, there have been few reports of this rare event in the literature.

Vaginal Access Minimally Invasive Surgery (VAMIS): A New Approach to Hysterectomy.

Vaginal hysterectomy is the original natural orifice operation. Although one of the most common gynecologic operations performed, the surgical approach has not changed significantly during the past century. This article describes a new approach to hysterectomy using vaginal access minimally invasive surgery (VAMIS).

Sphincter-sparing surgery for adenocarcinoma of the distal 3 cm of the true rectum: results after neoadjuvant therapy and minimally invasive radical surgery or local excision.

Background: Ideal treatment of rectal cancer includes controlling the cancer; minimizing trauma, morbidity, and mortality; and avoiding a colostomy with preservation of adequate function. These goals become more challenging the further distal in the rectum the cancer is located. We sought to determine whether minimally invasive sphincter-preservation surgery (SPS) can accomplish good cancer control, maintaining sphincter function with minimal morbidity and mortality in rectal cancers of the distal 3 cm after receiving neoadjuvant chemoradiotherapy.
