A systematic review and meta-analysis of variants of the branches of the superior mesenteric artery: the Achilles heel of right hemicolectomy with complete mesocolic excision?

Aim: Dissection with subsequent ligation and resection of arteries at their origin (central vascular ligation) is essential for adequate oncological resection during right hemicolectomy with complete mesocolic excision. This technique is technically demanding due to the highly variable arterial pattern of the right colon. Therefore, this study aims to provide a comprehensive evidence-based assessment of the arterial vascular anatomy of the right colon. Methods: A thorough systematic literature search through September 2020 was conducted on the electronic databases PubMed, Scopus and Web of Science to identify studies eligible for inclusion. Data were extracted and pooled into a meta-analysis using MetaXl software. Results: A total of 41 studies (n = 4691 patients) were included. The ileocolic artery (ICA), right colic artery (RCA) and middle colic artery (MCA) were present in 99.7% (95% CI 99.4%–99.8%), 72.6% (95% CI 61.3%–82.5%) and 96.9% (95% CI 94.2%–98.8%) respectively of patients. Supernumerary RCA and MCA were observed in 3.2% and 11.4% respectively of all cases. The RCA shared a common trunk with the ICA and MCA in 13.2% and 17.7% respectively of patients. A retro-superior mesenteric vein course of the ICA and RCA was observed in 55.1% and 11.4% respectively of all cases. Conclusion: The vascular anatomy of the right colon displays several notable variations, namely the absence of some branches (RCA absent in 27.4% of cases), supernumerary branches, common trunks, and retro-superior mesenteric vein courses. These variations should be taken into consideration during right hemicolectomy with complete mesocolic excision to ensure adequate oncological resection while minimizing intra-operative complications

Preventing the next pandemic: Zoonotic diseases and how to break the chain of transmission

Zoonotic diseases (also known as zoonoses) are caused by germs that spread between animals and people.However, animals can sometimes carry harmful germs that can spread to people and cause illness – these are known as zoonotic diseases or zoonoses. Zoonotic diseases are caused by harmful germs like viruses, bacterial, parasites, and fungi. These germs can cause many different types of illnesses in people and animals, ranging from mild to serious illness and even death. Animals can sometimes appear healthy even when they are carrying germs that can make people sick, depending on the zoonotic disease

Morphodynamics of Barrier Systems: A Synthesis

The morphodynamics of open-ocean barrier systems (barrier islands, barrier spits, and mainland or headland beaches), synthesizing classic studies, current scientific knowledge, and future research directions regarding a number of barrier systems globally are reviewed. Within a coastal tectonic framework, the authors address: (1) Amero-trailing-edge coasts (USA\u27s New England coast, mid-Atlantic Bight coast, North Carolina Outer Banks, Georgia Bight coast, and Florida Atlantic coast; Brazil\u27s Santa Catarina coast; German Bight coast; and southern and western Australian coasts); (2) marginal-sea coasts (USA\u27s Florida Gulf Coast; Gulf Coast of Alabama, Mississippi, and Louisiana; Texas Gulf Coast; and eastern Australian coast); and (3) collision coasts (USA\u27s Alaskan Pacific coast and New Zealand). Moreover, the chapter includes a glossary and robust current set of references
