Basic anatomic principles of pediatric colorectal and reconstructive surgery
Published in Alejandra Vilanova-Sánchez, Marc A. Levitt, Pediatric Colorectal and Pelvic Reconstructive Surgery, 2020
Right colon: Is supplied by the ileocolic trunk and the middle colic artery. The middle colic artery generally divides early in its course into right and left branches. The left branch usually forms a well-developed marginal artery that connects with the left colic artery at the splenic flexure. The origin of the middle colic artery is from the superior mesentery in most cases and is absent in 5%–8% of the population. The marginal blood supply at the splenic flexure is poor in 32% of the population and absent in 7%. The marginal anastomosis between the right colic and ileocolic arteries is absent in 5% of subjects [4, 5].

The blood supply to the colon and rectum is derived from branches of the superior mesenteric, inferior mesenteric, and internal iliac arteries. The right colon is supplied by the SMA through the ileocolic artery, the right colic artery, and a branch of the middle colic artery. The transverse colon is chiefly supplied by the middle colic artery, but there is a communication with the inferior mesenteric arterial system via the marginal artery of Drummond. The inferior mesenteric artery supplies the colon from the splenic flexure to the proximal rectum. The inferior mesenteric artery branches into the left colic artery, the superior rectal artery, and the sigmoid arteries. The distal rectum receives its blood supply from the paired middle and inferior rectal arteries which originate from the internal iliac artery system (Figure 29.10).
Use of the stomach as an esophageal substitute

Colonic blood supply is highly variable, with classic branches of the superior mesenteric artery only present 70% of the time. Attention should be given to the middle colic artery and the marginal artery arcade at the splenic flexure. Both of these areas have variable anatomy and the latter arcade is absent in 5% of patients. Multiple middle colic arteries make for a tenuous distal graft and difficult dissection. Similarly, an absent middle colic artery or middle colic artery originating from the coeliac trunk makes for dubious blood supply to the distal end of the graft and often precludes using the colon. Interruption of the marginal arcade at the splenic flexure is well reported on angiographic series, but, in practice, it rarely appears to be of clinical importance.

In cases of splenic flexure tumors, extended left colon resection was undertaken. The distal 2/3 of the transverse colon and left colon was performed in accordance with CME and CVL. During CME and CVL, ligation was performed at the point where the left colic artery branches off the inferior mesenteric artery along the aortic border and at the exit point of the left middle colic artery. The left-GEOM region covering the gastrocolic ligaman and omentum was dissected along a vertical line drawn from the transverse colon into the stomach from at least 10 cm proximal of the tumor and included in the specimen together with the infrapancreatic lymph nodes and the distal part of the anterior pancreas peritoneum. The right branch of the middle colic artery was preserved. Anastomosis was undertaken between the transverse and sigmoid colon.

The surgical procedure differs in the central lymphadenectomy and has previously been described [3,7,8]. The plane for the central dissection is between the superior mesenteric vessels and their sheaths. All tissue anterior and posterior to the superior mesenteric vessels from 5 mm proximal to the middle colic artery origin to 10 mm distal to the ileocolic artery origin is removed. The medial border follows the left border of SMA (Figure 1).

Next, the ascending colon was mobilized from medial to lateral and the ileocolic vessels ligated and transected. Finally, the middle colic artery (MCA) was isolated, clipped, and dissection of the mesocolon was performed from medial to lateral at the liver flexure, with full mobilization of the right colon and terminal ileum. A midline sub-umbilical mini-laparotomy was performed and the specimen was extracted.
