LIRRH Trial for the Right-sided Colon Cancer

The ileocolic vessels are divided at their roots, and lymph nodes of stations 203, 202, and 201 are dissected. The right colic and middle colic vessels are also divided at their roots, and the surrounding lymphatic and adipose tissue (stations 211/212/213 and 221/222/223) is cleared. The transverse colon is transected 10 cm distal to the tumor, and the ileum is divided 10 cm proximal to the ileocecal region. After tailoring the ileal mesentery, an end-to-end ileo-transverse colonic anastomosis is performed. Using a seromuscular suture, the ileum and its tailored mesentery are invaginated into the wall of the transverse colon 2 cm proximal to the anastomosis, thereby reconstructing the ileocecal valve complex.

The ileocolic vessels are divided at their roots, and lymph nodes of stations 203, 202, and 201 are dissected. The right colic and middle colic vessels are likewise divided at their roots, and the surrounding lymphatic and adipose tissue (stations 211/212/213 and 221/222/223) is cleared. The transverse colon is transected 10 cm distal to the tumor, and the ileum is divided 10 cm proximal to the ileocecal junction. An end-to-side or side-to-side ileo-transverse colonic anastomosis is then performed.
