Abstract:
The mesentery is the organ in which all abdominal digestive organs develop, and which maintains these in systemic continuity in adulthood. Interest in the mesentery was rekindled by advancements of Heald and Hohenberger in colorectal surgery. Conventional descriptions hold there are multiple mesenteries centrally connected to the posterior midline. Recent advances first demonstrated that, distal to the duodenojejunal flexure, the mesentery is a continuous collection of tissues. This observation explained how the small and large intestines are centrally connected, and the anatomy of the associated peritoneal landscape. In turn it prompted recategorisation of the mesentery as an organ. Subsequent work demonstrated the mesentery remains continuous throughout development, and that abdominal digestive organs (i.e. liver, spleen, intestine and pancreas) develop either on, or in it. This relationship is retained into adulthood when abdominal digestive organs are directly connected to the mesentery (i.e. they are ‘mesenteric' in embryological origin and anatomical position). Recognition of mesenteric continuity identified the mesenteric model of abdominal anatomy according to which all abdominal abdomino-pelvic organs are organised into either a mesenteric or a non-mesenteric domain. This model explains the positional anatomy of all abdominal digestive organs, and associated vasculature. Moreover, it explains the peritoneal landscape and enables differentiation of peritoneum from the mesentery. Increased scientific focus on the mesentery has identified multiple vital or specialised functions. These vary across time and in anatomical location. The following review demonstrates how recent advances related to the mesentery are re-orientating the study of human biology in general and, by extension, clinical practice.

Abstract:
AbstractThe recent description and re-classification of the mesentery as an organ prompted renewed interest in its role in physiological and pathological processes. With an improved understanding of its anatomy, accurately and reliably assessing the mesentery with non-invasive radiological investigation becomes more feasible.Multi-detector computed tomography is the main radiological modality employed to assess the mesentery due to its speed, widespread availability, and diagnostic accuracy.Pathologies affecting the mesentery can be classified as primary or secondary mesenteropathies. Primary mesenteropathies originate in the mesentery and subsequently progress to involve other organ systems (e.g., mesenteric ischemia or mesenteric volvulus). Secondary mesenteropathies describe disease processes that originate elsewhere and progress to involve the mesentery with varying degrees of severity (e.g., lymphoma).The implementation of standardized radiological imaging protocols, nomenclature, and reporting format with regard to the mesentery will be essential in improving the assessment of mesenteric anatomy and various mesenteropathies.In this article, we describe and illustrate the current state of art in respect of the radiological assessment of the mesentery.

Abstract:
AbstractRecent findings related to the mesentery clarified the organisation of the abdomen at the foundational level. The Mesenteric-based model of abdominal anatomy articlulates a foundation that re-unites scientific and clinical approaches to the abdomen in health and disease. Importantly, recent advances are a reminder that we must always question dogma. The peritoneal-based dogma of conventional anatomy remained unquestioned for too long. With time, the mesenteric-based dogma will also be altered and improved on. Anatomy, and hence surgery, must always be considered as works in progress.

Abstract:
AbstractThis article summarizes the events that shaped our current understanding of the mesentery and the abdomen. The story of how this evolved is intriguing at several levels. It speaks to considerable personal commitment on the part of the pioneers involved. It explains how scientific and clinical fields went different directions with respect to anatomy and clinical practice. It demonstrates that it is no longer acceptable to adhere unquestioningly to models of abdominal anatomy and surgery. The article concludes with a brief description of the Mesenteric Model of abdominal anatomy, and of how this now presents an opportunity to unify scientific and clinical approaches to the latter.

Abstract:
Aim. To analyze Inferior Mesenteric Artery in fetuses through its site of origin, length, diameter, and variation of its branches.Method. 100 fetuses were collected from various hospitals in Warangal at Kakatiya Medical College in Andhra Pradesh, India, and were divided into two groups, group I (second-trimester fetuses) and group II (third-trimester fetuses), followed by dissection.Result.(1) Site of Origin. In group I fetuses, origin of Inferior Mesenteric Artery was at third lumbar vertebra in 33 out of 34 fetuses (97.2%). In one fetus it was at first lumbar vertebra, 2.8%. In all group II fetuses, origin of Inferior Mesenteric Artery was at third lumbar vertebra.(2) Length. In group I fetuses it ranged between 18 and 30 mm, average being 24 mm except in one fetus where it was 48 mm. In group II fetuses the length ranged from 30 to 34 mm, average being 32 mm.(3) Diameter. In group I fetuses it ranged from 0.5 to 1 mm, and in group II fetuses it ranged from 1 to 2 mm, average being 1.5 mm.(4) Branches. Out of 34 fetuses of group I, 4 fetuses showed variation. In one fetus left colic artery was arising from abdominal aorta, 2.9%. In 3 fetuses, Inferior Mesenteric Artery was giving a branch to left kidney, 8.8%. Out of 66 fetuses in group II, 64 had normal branching. In one fetus left renal artery was arising from Inferior Mesenteric Artery, 1.5%, and in another fetus one accessory renal artery was arising from Inferior Mesenteric Artery and entering the lower pole of left kidney.Conclusion. Formation, course, and branching pattern of an artery depend on development and origin of organs to attain the actual adult position.

Abstract:
Introduction: It is now well established that mesenteric-based colorectal surgery is associated with superior outcomes. Recent anatomic observations have demonstrated that the mesenteric organ is contiguous from the duodenojejunal to the anorectal junction. This led to similar observations in relation to associated peritoneum and fascia. The aim of this review was to demonstrate the relevance of the contiguity principle to resectional colorectal surgery. Methods: All literature in relation to mesenteric anatomy was reviewed from 1873 to the present, without language restriction. Results: Mesenteric-based surgery (i.e. complete mesocolic excision, total mesocolic and mesorectal excision) requires division of the peritoneal reflection (i.e. peritonotomy), and mesenteric mobilisation in the mesofascial plane. These are the fundamental technical elements of mesenterectomy. Mesenteric, peritoneal and fascial contiguity mean that in resectional surgery, these technical elements can be reproducibly applied at all levels from the origin at the superior mesenteric root, to the anorectal junction. Conclusions: The goals of complete mesocolic, total mesocolic and mesorectal excision can be universally achieved at any level from duodenojejunal flexure to anorectal junction, by adopting technical elements based on mesenteric, peritoneal and fascial contiguity.

Abstract:
Currently, the growing interest in the structure of the vascular stream of the colon is due to the rapid development of abdominal and colorectal surgery.The aim of research was to study the variant anatomy of the sigmoid branches of the inferior mesenteric artery in men and women.Material and methods. The study included findings of multi-slice spiral computed tomography; a total of 2300 computed tomograms of adults aged 25 to 75 years (913 men and 1387 women) were investigated. Variants of the architectonics of the inferior mesenteric artery were differentiated by the presence and nature of the origin of its sigmoid branches, for which standard axial images and a series of post-processing images were used.Results. There have been identified sequential, stem and mixed types of branching of the inferior mesenteric artery. In the sequential type, the left colic and all sigmoid arteries separate from the inferior mesenteric artery; with a stem, two or more branches depart from the inferior mesenteric artery by a common vessel; in the mixed type, two left colic arteries sequentially depart from the inferior mesenteric artery. It has been proven that in both sexes the predominant type of branching of the inferior mesenteric artery is the stem: in men it is noted in 62% of cases, in women – in 63%, the mixed type of branching of the inferior mesenteric artery is the rarest, noted only in 2.4% of cases.Conclusion. The obtained information is of practical significance in abdominal, vascular, X-ray endovascular surgery, transplantology, coloproctology, and radiation diagnostics.

Abstract:
The recent introduction of multidetector computed tomography scanners has significantly improved computed tomography angiographic (CTA) applications, especially for the evaluation of medium- and small-arterial structures. CTA of the superior mesenteric artery has been reported previously. However, there have been few systematic and detailed reviews of the superior mesenteric artery pathologies that use CTA. The purpose of this pictorial essay is mainly to review the various superior mesenteric artery pathologies at CTA with our own experiences.

Abstract:
The aim of this study was to detect and describe the existence and incidence of anatomical variations of the celiac trunk and superior mesenteric artery. The study was conducted on 150 persons, who underwent abdominal Multi- Detector Computer Tomography (MDCT) angiography, from April 2010 until November 2012. CT images were obtained with a 64-row MDCT scanner in order to analyze the vascular anatomy and anatomical variations of the celiac trunk and superior mesenteric artery. In our study, we found that 78% of patients have a classic anatomy of the celiac trunk and superior mesenteric artery. The most frequent variation was the origin of the common hepatic artery from the superior mesenteric artery (10%). The next variation, according to frequency, was the origin of the left gastric artery direct from the abdominal aorta (4%). The arc of Buhler as an anastomosis between the celiac trunk and superior mesenteric artery, was detected in 3% of cases, as was the presence of a common trunk of the celiac trunk and superior mesenteric artery (in 3% of cases). Separate origin of the splenic artery and the common hepatic artery was present in 2% of patients. The MDCT scanner gives us an insight into normal anatomy and variations of the abdominal blood vessels, which is very important in the planning of surgical interventions, especially transplantation, as well as in the prevention of complications due to ischemia.

Abstract:
Les lésions traumatiques de l’intestin sont responsables d’une part importante de la morbidité et de la mortalité consécutives aux lésions traumatiques abdominales. Elles sont pourtant mal connues. Les mécanismes à l’origine de ces blessures sont mal compris alors qu’un rôle paradoxalement négatif de l’usage de la ceinture de sécurité automobile est suspecté. En pratique clinique, le diagnostic précoce reste difficile, alors qu’une relation directe entre le délai diagnostic et le pronostic a été établi. Les règles de prise en charge thérapeutique ne sont pas consensuelles. Concernant la recherche, les quelques données de la littérature sur le comportement mécanique de l’intestin n’ont été obtenues qu’en condition quasi-statique ne reflétant pas les conditions d’un traumatisme. Le présent travail fait le lien entre données cliniques et travaux de recherche. Il apporte des connaissances pratiques sur un certain nombre de questions: quelles sont les situations à risque de chirurgie ? Comment se crée une lésion traumatique intestinale par décélération? Quelles sont les propriétés mécaniques de l’intestin qui dépendent de la cinétique du traumatisme ? Quelles sont les données anthropométriques et issues de l’imagerie médicale qui expliquent la variabilité de l’anatomie de l’intestin et de son mésentère ? Ces travaux serviront de base pour l’élaboration de modèles numériques d’hommes virtuels personnalisés et bio-fidèles utilisables dans le cadre de la traumatologie virtuelle. Ces outils de simulation numérique permettront de valider nos hypothèses sur le processus traumatique et participeront à l’amélioration des moyens de prévention de ces lésions traumatiques
Traumatic injuries of the intestine are responsible for a significant proportion of the morbidity and mortality in blunt abdominal trauma. Nevertheless they are known very badly. The mechanisms involved are poorly understood despite the fact that a negative effect in the use of car seat belts is suspected. In clinical everyday practice, early diagnosis is often difficult, whereas a direct relationship between diagnosis delay and prognosis has been established. No consensus from academic society is available to help the therapeutic management. Regarding biomechanical research, the few data on the mechanical behavior of the intestine were obtained only in quasi-static condition and so does not reflect the conditions of trauma. The present work creates the link between clinical and research work. It provides practical knowledge on a number of questions: what situations are at risk of surgery? How intestinal injury occurs during traumatic deceleration? What are the mechanical properties of the intestine that depend on the velocity of trauma? What are the anthropometric data from medical imaging that explain the variability of the intestinal and mesenteric anatomy? This work constitutes the basis for the further development of numerical bio-faithful models of humans that could be used in virtual trauma applications. These numerical simulation tools will validate our assumptions about the traumatic process and will participate in the improvement of prevention means

Abstract:
Transmesenteric portal access via mini-laparotomy may be used as a salvage technique when standard transjugular intrahepatic portosystemic shunt (TIPS) is unsuccessful due to difficult anatomy or portal vein thrombosis. This technique allows for precise determination of both the portal and the hepatic vein branch involved in the TIPS. This method usually involves the cooperation of a surgeon, who performs a mini-laparotomy and exposes a small bowel loop in the interventional suite. A mesenteric venous branch is then cannulated, providing direct access to the portal venous system. In distinction to standard technique, the hepatic parenchymal tract is created by a puncture from the portal vein into the hepatic vein. A guidewire advanced through the puncture needle is then snared from the hepatic vein, providing through-and-through access. The TIPS can be completed using standard techniques. Upon completion, the mini-laparotomy is closed by the surgeon.
