“…Classical methods of cadaveric dissection lead the student with the erroneous impression there are multiple individual regions of mesentery (25,26). The correlation of anatomic, surgical, and radiological imaging of the continuous mesentery is likely to greatly assist the translation of the findings of this study to clinically benefit patients (27).…”

Development of a Novel Technique to Dissect the Mesentery That Preserves Mesenteric Continuity and Enables Characterization of the ex vivo Mesentery

Introduction: The conventional model of abdominal anatomy described multiple mesenteries. Dissection techniques were based on this. Recent studies demonstrate the mesentery is continuous from duodenojejunal flexure to anorectal junction. Given this, it is important to update dissection techniques related to the mesentery in the cadaveric setting. Materials and Methods:A technique of mesenteric dissection was developed and tested in a cohort of 20 adult human cadavers (12 male and 8 female). As the technique enabled excision of the mesentery as a single unit, it was possible to characterize the anatomy of the ex vivo mesentery.Results: The technique developed enabled dissection of an intact and continuous mesentery in all cadavers examined. Examination of the ex vivo mesentery demonstrated that a mesoduodenum was present in all cases. The mesentery was continuous from the mesoduodenum to the mesorectum and ended at the level of the anorectal junction. Conclusions:A technique was developed that reproducibly enabled dissection of an intact and continuous mesentery from the duodenum to the anorectal junction. A mesoduodenum was consistently observed and noted to be in continuity with the remainder of the mesentery.

“…According to surgical dissections (2,27), the mesentery is continuous and the presence of continuity from duodenojejunal flexure to anorectal junction is now considered as normality. However, few anatomical studies have characterized the mesentery in the cadaveric setting.…”

“…The liver forms in the ventral mesogastrium, which gives rise to the falciform ligament, gastrohepatic ligament (GHL), and hepatoduodenal ligament (HDL), which attach the stomach and duodenum to the anterior abdominal wall. The spleen and pancreas form within the dorsal mesogastrium, which fuses with the posterior abdominal wall to form the gastrocolic ligament (GCL), gastrosplenic ligament (GSL), and splenorenal ligament (SRL) (36,37).…”

Ligaments and Lymphatic Pathways in Gastric Adenocarcinoma

Gastric cancer is a leading cause of cancer-related deaths worldwide and is associated with an overall 5-year survival rate of less than 20%. The most common histologic subtype of gastric cancer is adenocarcinoma. Imaging techniques for evaluating gastric adenocarcinoma include endoscopic US, fluoroscopic upper gastrointestinal imaging, CT, PET/CT, and MRI. Hydrodynamic multiphasic contrast material-enhanced CT is the imaging modality of choice for preoperative clinical staging of regional, nodal, and metastatic involvement. Radiologic manifestations of gastric adenocarcinoma at double-contrast upper gastrointestinal imaging and CT include polyps, ulceration, indistensibility, wall thickening, and abnormal enhancement. There are multiple pathways of disease spread. These pathways include lymphatic dissemination; subperitoneal dissemination along the perigastric ligaments, mesentery, or omentum; direct invasion into adjacent organs; transperitoneal seeding; and hematogenous dissemination. The spread of disease is affected by the location of the tumor in the stomach, and the ligamentous and lymphatic anatomy. Key imaging features that affect clinical staging with use of the TNM classification system for gastric adenocarcinoma, as described in the eighth edition of the AJCC Cancer Staging Manual, are briefly discussed. Accurate radiologic assessment of gastric adenocarcinoma requires identification of perigastric ligament infiltration, regional and metastatic nodal disease, and direct and metastatic organ involvement, all of which directly affect tumor staging, treatment, and prognosis. ©

“…El espacio extraperitoneal (EE) se encuentra delimitado por el peritoneo parietal y las paredes de la cavidad abdómino-pélvica (Skandalakis et al, 2004). La complejidad del EE está dada porque ha sido objeto de múltiples subdivisiones por diversos autores (Rouviere y Delmas, 1999;Testut y Jacob, 1979;Paturet, 1951), así como la escasez de signo-sintomatología que manifiestan las condiciones patológicas que se producen dentro del EE (Meyers et al, 2011). De hecho los tejidos del EE no "reaccionan" de forma tan aguda y severa a la contaminación bacteriana como sucede en la cavidad peritoneal (Meyer, 1934).…”

El espacio extraperitoneal se encuentra delimitado por el peritoneo parietal y las paredes de la cavidad abdómino-pélvica. Al igual que la cavidad peritoneal este espacio puede ser asiento de diversas colecciones, como ser hematomas, tumores y supuración. Con el advenimiento de las nuevas técnicas de imagen, se ha contribuido no solo al mejor diagnóstico de estas patologías sino también a su mejor manejo. El objetivo de este trabajo es mostrar la anatomía del abordaje extraperitoneal del comparti-miento del psoas y su aplicación al tratamiento de un paciente. Para esto se utilizaron 5 cadáveres adultos fijados previamente en solución en base a formol. Se realizó disección bilateral de la pared antero-lateral del abdomen reclinando la bolsa peritoneal para a continuación abordar el compartimiento del músculo psoas. Este conocimiento fue utilizado en el tratamiento quirúrgico de una paciente que consultó por un absceso del compartimiento del psoas derecho. En las preparaciones cadavéricas, se observó cómo al rebatir el peritoneo parietal se expone la totalidad del compartimiento muscular del psoas. Este procedi-miento fue realizado a la paciente consiguiendo el drenaje completo de la cavidad abscedada, quien tuvo una buena evolución y fue dada de alta a los 7 días. Los hallazgos demuestran una vez más como el conocimiento anatómico sigue estando vigente en la práctica clínica, siendo la comprensión del espacio extraperitoneal fundamental no solo para el anatomista sino también para el cirujano. The retroperitoneal space is bounded by the parietal peritoneum and the posterior abdominal wall. Just like the peritoneal cavity, this region can host multiple effusions such as hematomas, tumors and suppuration. With the development of new radiological technics, both diagnosis and management of these conditions has improved. The purpose of this paper is to demonstrate the anatomy of the extraperitoneal approach of the psoas compartment and its application to a patient´s surgical treatment. For this purpose 5 formalin-fixed adult cadavers were used. Bilateral dissection of the antero-lateral abdominal wall was performed in every specimen. Once the parietal peritoneum was mobilized the psoas compartment was approached. This knowledge was used during the surgical treatment of a patient who attended to the emergency room with a right psoas compartment abscess. In the cadaveric specimens, the psoas muscular compartment was approached after mobilizing the parietal peritoneum medially. This procedure was carried out in the patient resulting in complete drainage of the purulent effusion. The patient had complete relief of the symptoms and was discharged 7 days after the procedure. These findings show that the anatomic knowledge is still important in clinical practice. Understanding the extraperitoneal space is crucial for both anatomists and surgeons.
