Research progress on surgical approach and intestinal anastomosis methods for laparoscopic right hemicolectomy: A review.

Patients with tumors located in the cecum, ascending colon, and hepatic flexure of the colon often use laparoscopic right hemicolectomy. Although with the help of laparoscope, the surgery is more visual and refined, due to the different shapes of the blood vessels and the different positions of the frequently occurring blood vessels, the surgeons face challenges during surgery. Improper operation may cause unnecessary damage. Therefore, in order to better solve the problem of variation and reduce intraoperative side injuries, we conducted a literature review on the surgical approach and the guidance of intraoperative anatomy, in order to find more reasonable and simplified surgical methods. At the same time, we conducted a review of various intestinal anastomosis methods to identify more effective approaches, aiming to reduce intestinal tension at the anastomosis site, decrease the incidence of anastomotic leakage, and better promote the recovery of postoperative intestinal function.
