RATIONALE: Robotic-assisted laparoscopic surgery may be a less invasive type of surgery for rectal cancer and may have fewer side effects and improve recovery. It is not yet known whether robotic-assisted laparoscopic surgery is more effective than laparoscopic surgery in treating patients with rectal cancer.
PURPOSE: This randomized clinical trial studies robotic-assisted laparoscopic surgery to see how well it works compared to laparoscopic surgery in treating patients with rectal cancer that can be removed by surgery.
I. To evaluate robotic-assisted rectal cancer surgery versus standard laparoscopic rectal cancer resection by means of a randomized, controlled trial.
II. To assess technical ease of the operation, as determined by the clinical indicator of low conversion rate to open operation.
III. To assess surgical accuracy and improved oncological outcome as determined by clear pathological resection margins.
IV. To assess quality of life and analyze cost-effectiveness to aid evidence-based knowledge to inform NHS and other service providers and decision-makers.
V. To analyze disease-free and overall survival and local recurrence rates at 3-year follow-up.
Patients are randomized to 1 of 2 treatment arms.
ARM I: Patients undergo standard laparoscopic resection.
ARM II: Patients undergo robotic-assisted laparoscopic resection.
After completion of study treatment, patients are followed up at 1 month, 6 months, and then annually thereafter for 3 years.

The indication of laparoscopic surgery is mainly for early regional type hepatolithiasis. Open surgery is the traditional treatment method for heptolithiasis. Da Vinci surgical robot can o...
The purpose of this study is to compare two ways of performing laparoscopic hysterectomy - robotic-assisted vs. conventional laparoscopy.
Colorectal cancer is a common malignancy in Viet Nam. Laparoscopic surgery becomes a standard treatment in many center. Today, robotic surgery is a new option for treating colorectal cance...
The use of robotic-assisted laparoscopic surgery has continued to grow since the Food and Drug Administration approval for robotic-assisted gynecologic surgery in 2005. However, despite this growth in...
Robotic surgery has been recently used as a novel tool for rectal surgery. This study assessed the current evidence regarding the efficiency, safety, and potential advantages of robotic rectal surgery...
The role of robotic assisted surgery in contemporary urolithiasis management is in its infancy. The mainstay in the management of renal tract calculi remains ureterorenoscopy (URS), extracorporeal sho...
To explore the perceptions and experiences of perioperative nurses and Certified Registered Nurse Anesthetists (CRNAs) in robotic-assisted laparoscopic surgery (RALS). The objective was to identify th...
This study was to introduce the modified mini-laparoscopic surgery for renal cyst and investigate its advantages on operative time, cosmetic effect and pain reduction by comparison with laparo-endosco...
Surgical procedures conducted with the aid of computers. This is most frequently used in orthopedic and laparoscopic surgery for implant placement and instrument guidance. Image-guided surgery interactively combines prior CT scans or MRI images with real-time video.
Procedures that avoid use of open invasive surgery in favor of closed or local surgery. These generally involve use of laparoscopic devices and remote-control manipulation of instruments with indirect observation of the surgical field through an endoscope or similar device. With the reduced trauma associated with minimally invasive surgery, long hospital stays may be reduced with increased rates of short stay or day surgery.
Procedures that avoid use of open, invasive surgery in favor of closed or local surgery. These generally involve use of laparoscopic devices and remote-controlled manipulation of instruments with indirect observation of the surgical field through an endoscope or similar device.
Endoscopic surgical procedures performed with visualization via video transmission. When real-time video is combined interactively with prior CT scans or MRI images, this is called image-guided surgery (see SURGERY, COMPUTER-ASSISTED).
Placement of one of the surgeon's gloved hands into the ABDOMINAL CAVITY to perform manual manipulations that facilitate the laparoscopic procedures.
Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
Head and neck cancers
Cancer can occur in any of the tissues or organs in the head and neck. There are over 30 different places that cancer can develop in the head and neck area. Mouth cancers (oral cancers) - Mouth cancer can develop on the lip, the tongue, the floor...
Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for the organ or type of cell in which they start - for example, cancer that begins in the colon is called colon cancer; cancer th...
