Laparoscopic colorectal surgery has become a standard of care in colorectal cancer surgery, providing comparable long-term outcomes to those in open surgery [[1]]. Medially at the level of the inferior mesenteric artery root and the left colic artery debranching the parietal fascia is cut along the right side of the aorta to free the medial border of the mesocolon. We perform low vascular ligation and preserve the left colic artery in the case of sigmoid and rectal cancer surgery, reaching apical lymph node dissection due to skeletonization of the inferior mesenteric artery, which stands for vascular-oriented complete lymph node dissection [[5]].

Distal sigmoid colon resection with vascular-oriented D2 lymph node dissection and transrectal specimen extraction (NOSES II) In this video (Video S1) we present the key steps of anterior rectal resection with D2 lymph node dissection (D2 LND) and transrectal specimen extraction using NOSES type II. Natural orifice specimen extraction surgery (NOSES) is widely implemented in colorectal surgery, minimizing the trauma associated with mini-laparotomy during conventional laparoscopic surgery.

Stoma orifice specimen extraction surgery for rectal cancer with D3 lymph node dissection and liver resection - a video vignette Laparoscopic anterior resection of the rectum is one of the surgical procedures used for rectal cancer treatment [[1]]. The technique of stoma orifice specimen extraction surgery (or SOSES) allows an additional abdominal incision to be avoided, shortens the postoperative period and minimizes postsurgery complications [[2]].

In Video S1, we present the key steps of total proctocolectomy with the formation of an ileal pouch-anal anastomosis and D3 lymph node dissection. Total proctocolectomy with ileal pouch-anal anastomosis and D3 lymph node dissection with inflammatory bowel disease associated colon cancer - a video vignette I Dear Editor i , The incidence of colorectal cancer (CRC) in inflammatory bowel disease (IBD) patients was reported to be higher than in the general population [1,2].

In the first step, skeletonization of the inferior mesenteric artery was performed for identification of the left colic artery, preserving the inferior mesenteric artery and removal of the 253 lymph nodes. In Video S1 we demonstrate the bidirectional D3 lymph node dissection technique with removal of both 253 and 223 groups of lymph nodes [4]. Splenic flexure colon cancer can be associated with metastasis along both the left colic artery and the left branch of the middle colic artery [2,3]. [Extracted from the article]
