Editorial

The Anatomic variations of the right colon vasculature are complex, and indecorous operation of vessels during laparoscopic surgery can beget vascular complications . Studies of right colon vascular variations could potentially minimize the threat of complications. Utmost former necropsy and imaging studies of the right colon have concentrated on highways rather than modes, although venous feeders of the right colon were lately described in a Japanese cohort using three-dimensional (3D) reckoned tomography (CT) . Nevertheless, variations of right colon vascularity in Chinese people remain uncharacterized. Preoperative 3D-CT vascular reconstruction isn’t performed routinely due to radiation pitfalls and other considerations [1].

We consider that a detailed knowledge of right colon vascular variations is important to ameliorate safety and reduce the pitfalls of vascular complications during minimally invasive surgery. This study aimed to retrospectively review high- resolution vids of laparoscopic radical right colectomy (LRRC) and explore right colon vascular variations in order to epitomize the patterns of the variations and identify styles of managing with these variations during surgery. It was anticipated that our findings would give a useful reference for surgeons [2, 3].

This retrospective study enrolled cases who passed LRRC at the Department of Tumour Surgery, Alternate Affiliated Hospital of Fujian Medical University (March 2013 to October 2016). The original ethics commission approved the study. All procedures were in agreement with ethical norms of the applicable commission on mortal trial and Helsinki Declaration. Informed concurrence was waived because the study was retrospective.

Successive cases were originally enrolled grounded on the following addition criteria (1) nasty colonic lump clinically or pathologically diagnosed before surgery; (2) excrescence on the ileocecal stopcock, thrusting colon or hepatic flexure (distal end< 10 cm from the transverse colon); (3) LRRC performed between March 2013 and October 2016; (4) standard D3 lymph knot analysis accepted according to the complete mesocolic excision principle. The following rejection criteria were also applied (1) roadway- tone groups or compositions uncelebrated due to ineligible norms for D3 lymph knot analysis (one case); (2) vids unclear, deficient, or damaged (five cases); (3) insolvable to distinguish roadway- tone groups/compositions due to inordinate haemorrhage/blurred operative fields (three cases); (4) palliative rather than radical resection performed (five cases). Grounded on the addition and rejection criteria, the final analysis included 60 cases [4-7].

The mesocolon-mesoileum junction was cut at the inferior ileocolic periphery. Via this window, Toldt’s gap was extended to expose the vertical/ descending part of the duodenum. The superior mesenteric tone was divided up to the inferior pancreatic periphery. The ileocolic roadway and right bellyache roadway anterior to the superior mesenteric tone were linked and clamped/ transacted. The right posterior colon space was extended superiorly, and the superior pancreatic duodenal tone, right bellyache tone, and gastro colic box of Henley were linked. The superior mesenteric tone was clamped/ transacted. The middle bellyache roadway was linked at the pancreatic neck. For extended LRRC, the middle bellyache roadway was clamped/transacted at the root, and complete lymph knot analysis was performed. For standard LRRC, the left branch of the middle bellyache roadway was saved. The middle bellyache tone, linked after opening the superior mesenteric tone jacket, was clamped/transected. The gastrocolic box of Henle and feeders were linked, and every branch was divided. For standard LRRC, the anterior superior pancreatic duodenal tone was saved while the right gastro-omental tone, right bellyache (and appurtenant right bellyache) tone, and middle bellyache tone were transected. For extended LRRC, the gastrocolic box of Henle was clamped/transacted at its root [8-10].

The transverse colon was dislocated after division of the lower colon. For standard LRRC, the gastrocolic ligament was divided outside the gastroomental bow, Toldt’s gap was opened between the mesogastrium and transverse mesocolon, and the transverse mesocolon anterior lobe was opened from the inferior pancreatic periphery to the inferior region of the colon. For extended LRRC, group IV lymph bumps and lymphoid adipose towel within 10 cm of the pyloric bow were removed. The right gastro-omental roadway was linked and transected.

The veins that make up the blood supply to the human colon comprise a complicated structure that varies greatly from person to person. For surgical operations targeting this region, a thorough understanding of the anatomical variations of these veins is essential. The marginal artery of Drummond (MA), also known by its proper international anatomical nomenclature, “arteria mar- ginalis coli”, is one vascular of importance to medical practitioners. The superior mesenteric artery’s (SMA) area terminates at the distal end of the transverse colon, while the inferior mesenteric artery’s (IMA) territory begins at the splenic flexure. These two circulations are connected by a major collateral vessel (e.g., the MA), which creates a continuous arcade along the colon’s mesenteric border.
