ISOperistaltic Versus ANTIperistaltic Anastomosis After Laparoscopic Right Colectomy for Cancer

Randomized Clinical Trial Comparing Isoperistaltic Versus Antiperistaltic Side to Side Anastomosis After Right Laparoscopic Hemicolectomy for Cancer.

The study will provide a precise control compared to the two interventions (iso vs antiperistaltic anastomoses) with thorough measurements of the postoperative variables and complications to improve the evaluation of the surgical technique. It will also enable an evaluation of the quality of life after the procedures.
