The AMCA contributes to the vascularization of the splenic flexure in approximately 25% of individuals, and may be an important feeder artery to SFCs, especially in the absence of a LCA. This turn is known as the left colic flexure (or splenic flexure). The AMCA shared a common trunk/gave rise to pancreatic branches in 23.1% of cases (95% CI 15.3–31.9). In this article, we shall look at the anatomy of the colon its anatomical structure. The commonest origin for the AMCA was the superior mesenteric artery (PP = 87.9% 95% CI 86.4–90.7). What is the name of the pear-shaped organ located on the undersurface of the liver A. Its prevalence was higher in patients without a left colic artery (LCA) (PP = 83.2% 95% CI 70.4–93.1). Which of the following is not a part of the Large intestine A. ResultsĪ total of 16 studies ( n = 2203 patients) were included. While gas is normal, splenic flexure syndrome. Data were extracted and prevalence was pooled into a meta-analysis using MetaXL and Meta-Analyst software. Your splenic flexure is in the sharp bend between your transverse colon and descending colon in your upper abdomen. MethodĪ systematic search of the scientific literature was conducted on PubMed and Embase from inception to November 2020 to identify potentially eligible studies. The aim of this study is to determine the prevalence and anatomical features of the AMCA. The descending colon lies on the posterior abdominal wall muscles and is closely related to the left ureter. It turns downwards as the descending colon, which, like the ascending colon, is retroperitoneal. It is held on to the diaphragm by a peritoneal fold, the phrenicocolic ligament on which the spleen sits. The accessory middle colic artery (AMCA) is increasingly being recognized as an important source of blood supply to the splenic flexure. The splenic flexure lies at a higher level compared with the hepatic flexure (Fig. Surgical resection of splenic flexure cancers (SFCs) is technically demanding due to the complex regional anatomy, characterized by the presence of embryological adhesions, close proximity to the pancreas and spleen, and a highly heterogeneous arterial supply and lymphatic drainage.
