Intracorporeal Anastomosis in Laparoscopic Left Colectomy. Cohort Comparative Study

"Standard surgical technique protocolized in the unit for laparoscopic surgery of the left colon, sigma and high rectum for the last 10 years.~After sectioning the distal colon using a mechanical stapler (60mm blue load), a pfannestiel-type suprapubic accessory incision is made, with externalization of the tumor under wound protection with a ringed retraction device. Both the resection of the left mesocolon or mesosigma, and the placement of the head of the circular stapler are performed extracorporeally by proximal section of the colon with a pursetring® self-suturing device, removal of the piece, placement of the head, and reconnection of the pneumoperitoneum for colorectal anastomosis with Circular Stapler Curved B. Braun®"

"o Intracorporeal resection of the left mesocolon~The mesocolon resection will be performed totally intracorporeally to its proximal end. The distal colon section will be performed using a mechanical stapler (blue charge 60mm)~o Preparation of Intracorporeal Anastomosis~The anastomosis will be performed in a mechanical end-to-end manner using a Circular Stapler Curved B. Braun®.~The Insertion of the stapler head into the proximal colon will be placed intracorporeally with an incision distal to the staple section. Once the head has been exteriorized at the terminal end of the proximal colon, a circular purse-type suture with prolene 2.0 will be made.~Once the mechanical colorectal anastomosis is performed, 4-6 stitches of anastomotic reinforcement with silk 2.0 will be placed.~The extraction of the piece will be carried out with endobag protection and with an accessory incision (pfannestiel or other location depending on the patient)"
