Fall of another myth for colon cancer: Duration of symptoms does not differ between right- or left-sided colon cancers.

Background/aims: Patients with colorectal cancer continue to present with relatively advanced tumors that are associated with poor oncological outcomes. The aim of the present study was to assess the association between localization, symptom duration, and tumor stage.

Materials And Methods: A prospective, multicenter cohort study was conducted on patients newly diagnosed with a histologically proven colorectal adenocarcinoma.

Is da Vinci Xi Better than da Vinci Si in Robotic Rectal Cancer Surgery? Comparison of the 2 Generations of da Vinci Systems.

Background: We aimed to compare perioperative outcomes for procedures using the latest generation of da Vinci robot versus its previous version in rectal cancer surgery.

Patients And Methods: Fifty-three patients undergoing robotic rectal cancer surgery between January 2010 and March 2015 were included. Patients were classified into 2 groups (Xi, n=28 vs.

Robotic complete mesocolic excision for right-sided colon cancer.

Complete mesocolic excision (CME) with central vascular ligation for right-sided colon cancer has been proven to provide superior oncologic outcomes and survival advantage when compared to standard lymphadenectomy [1]. A number of studies comparing conventional laparoscopic versus open CME have shown feasibility and safety of the laparoscopic approach with acceptable oncological profile and postoperative outcomes [2, 3]. The introduction of robotic systems with its technical advantages, including improved vision, better ergonomics and precise dissection, has further revolutionized minimally invasive approach in colorectal surgery.

Increased Caseload Volume is Associated With Better Oncologic Outcomes After Laparoscopic Resections for Colorectal Cancer.

Purpose: To evaluate the impact of caseload volume on the outcomes of open and laparoscopic surgery for colorectal cancer.

Methods: Between April 1999 and January 2011, patients who underwent open or laparoscopic resection for colorectal adenocarcinoma with curative intent were identified. There were 2 groups of surgeons, whose primary practice is gastrointestinal surgery (n=5, group A) and general surgery (n=14, group B).
