Clinical Outcomes and Prognostic Factors of Robotic Assisted Rectal Cancer Resection Alone vs. Robotic Rectal Cancer Resection With Natural Orifice Specimen Extraction
Study Details
Study Description
Brief Summary
Robotic rectal cancer resection with natural orifice extraction is a recently developed minimally invasive surgery for patients with rectal cancer. However, it's safety and feasibility remain undiscussed and controversial. This study reported the clinical outcomes and prognostic factors of robotic assisted rectal cancer resection alone vs. robotic rectal cancer resection with natural orifice extraction to discuss aforementioned question.

Detailed Description
Robotic rectal cancer resection with natural orifice extraction is a recently developed minimally invasive surgery for patients with rectal cancer. However, it's safety and feasibility remain undiscussed and controversial. This study reported the clinical outcomes and prognostic factors of robotic assisted rectal cancer resection alone vs. robotic rectal cancer resection with natural orifice extraction to discuss aforementioned question. From January 2015 to November 2016, a consecutive wave of 49 patients underwent robotic rectal cancer resection with natural orifice extraction and 49 matched patients underwent conventional robotic assisted rectal cancer resection were systematically analyzed in this study.

Outcome Measures
Primary Outcome Measures
- Overall survival [Up to 36 months]
To determine the survival differences between NOSE group and RARC group. Overall survival is defined as the time from surgery to death from any causes
- Disease-free survival [Up to 36 months]
To determine the survival differences between NOSE group and RARC group. Disease-free survival is defined as the time from surgery to local or distant recurrence
Secondary Outcome Measures
- Operation time [1 day]
To determine the differences between NOSE group and RARC group
- Estimated intraoperative blood loss [1 day]
