IN abdominal cavity Allocate visceral (domestic) and parietal (cloth) lymphatic nodes.
Curl lymph nodes,nodi. lymphatici. coeliaci.are localized near the crust on the line of Lymphs from many visceral lymph nodes Abdominal cavity.
Gastric lymph nodes,nodi. lymphatici. gastrici.. Left gastric lymph nodes,nodi. lymphatici. gastrici. sinistri.Located near the left gastric artery and its branches, fit to the small curvature of the stomach and its walls (front and rear). The lymphatic vessels of the small curvature of the stomach fall into these nodes.
Right gastric lymph nodes,nodi. lymphatici. gastrici. dextri., non-permanent, are located in the course of the type of artery over the gatekeeper.
Pilorary lymphaticnodes nodi. lymphatici. pilorici., are above the gatekeeper, behind it and under it, next to the upper gastrointestinal artery. Lymphatic vessels from the gatekeeper of the pancreas playing gladers are flowing into the pylorical nodes.
Along the great curvature of the stomach are located right and left gastrointestinal nodes. They lie in the form of chains near the same-name arteries and veins and take lymphatic vessels in which Lymph is coming from the stomach walls, adjacent to great curvature, as well as from the Big Self.
Spleen lymph nodes,nodi. lymphdtici. liendles., are located at the gate of the spleen, near the branching of the spleen artery, in the thickness of the gastrointestinal bundle. Lymphatic vessels are sent to these nodes from the bottom of the stomach, left gastrointestinal lymph nodes and from the spleen capsule.
Liver lymph nodes,nodi. lymphdtici. hepdtici., are in the thickness of the hepatic and duodenal bunch in the course of the general hepatic artery and the portal vein. They are also near the neck of the gallbladder - this bile lymph nodes,nodi. lymphatici. cysstici.. They take lymphatic vessels from the liver and gallbladder. Driving lychers and bile lymphatic vessels of hepatic and bile lymph nodes are sent to the curl and lumbar lymph nodes.
Lower left lymph nodes,nodi. lymphatici. epigastrici. inferiores., pair, lie in the thickness of the front abdominal wall in the course of the same name blood vessels. They collect lymphs from the adjacent parts of the straight, transverse and oblique muscles of the abdomen, the peritoneum, lining the front abdominal wall, and from the subvershiteline fiber.
Numerous lumbar lymph nodes,nodi. lYM. phathici. lumbdles., located all over the back of the abdominal wall (retroperitone) around the aorta and the lower hollow vein. Due to the position of these nodes in relation to major vessels, they are divided into left, right and intermediate lumbar lymph nodes.
On the back abdominal wall, near the bottom diaphragmal artery, the polar non-permanent single names are distinguished lower diaphragmal lymph nodes,nodi. lymphatici. phrenici. inferiores.. The lymphatic diaphragm vessels, the rear of the right and the left lobe of the liver fall into these nodes.
Lymph nodes of the abdominal cavity We are divided into viscerals, located along the trunks and branches of the ventricular barrel, the upper and lower mesenteric arteries, and parietal, or lumbar, lying around the aorta and the lower hollow vein. Lumbar nodes (NODI Lymphatici Lumbales) in turn are divided into left and right lateroautical and pre-retro-actival.
Right latero-soldered nodes consist of laatero, pre- and returkatal and instextocaval nodes. The laaterocavral node chain (1-8) begins on the node lying in the corner between the overall iliac artery and the lower hollow vein, and ends above the right renal leg on the CRUS dextrum diaphragm. The vessels of the nodes go to the returkatal nodes, in the right transdiaphragmal path and take part in the formation of the main roots of the chest duct. The extension vessels from the lower drock assemblies (among 1-7) above the beginning of the lower mesenteric artery enter or into interatokavalny, or in the pre-utteral, or in retur curb nodes. The upper non-permanent 1-2 drock assemblies lie on the front surface of the vein between the shift of the renal vein and the beginning of the lower mesenteric artery.
Right crop nodes (in quantity 1-9) are located behind the lower hollow vein. Of these, it is possible to distinguish the largest and permanent node (main), which flows below the level of liner into the lower hollow vein of the left renal vein. The existing vessels of the lower robbar nodes are most often in the main returder assembly, which is the main sources of a single or double right lumbar trunk, less often in the right lumbar lymphatic barrel. Inteathedral lymph nodes (in quantity 1-5) are located between the aorta and the lower hollow veins throughout the level of removal of the lower mesenteric artery to the vent. Immediately below the left renal vein lies the main node of this chain, in which the lymphatic vessels of eggs (or ovary) are poured, bringing the vessels of central mesenteric and rear pancreatododenal knots, kidneys, liver. The discharge vessels of the node are most often falling in Truncus Lumbalis Dexter.
Pre-routes are located on the front surface of the aorta at different levels: immediately above the aorta bifurcation (from 1 to 4 nodes), around the beginning of the lower mesenteric artery (from 1 to 7 nodes). On the site from the lower mesenteric artery to the lower edge of the left renal vein lie from 1 to 5 knots. Large, vessels from central mesenteric nodes, rear pancreatyododenal and retro pancreatic nodes fall into them. Above and behind the pancreas, at its lower edge, and above the left renal veins are pre-aircraft retropancreatic nodes (1-4), in which lymph leather from curl, hepatic, spleen and mesenteric nodes. At the base of Truncus, the Liacus is located 1-2 large nodes, which are part of NODI Lymphatici Coeliaci lying along the branches of the ventricular barrel. Their discharge vessels are sent to the upper left lateroactive, retro and laaterocaval knots and to preoperative retropancreatic nodes. Retro-aortic nodes (1-4) are located behind the aorta at all its length, connecting the left latero-solder nodes with returkatar or intero-shut-circuit nodes.
The right lumbar lymphatic barrel (Truncus Lumbalis Dexter) arises from the reducing vessels of the right latero-soldered and even pre-router nodes, which are connected in various combinations and form a single or multiple (up to three) trunk. Additional trunks fall into the chest duct. The right lumbar trunk is more often located between the abdominal aorta and the lower hollow vein, less often behind the veins or aorts. The fusion of lumbar trunks forms the chest duct.
Located mainly in mesenters, gates internal organs, along large blood vessels. The outflow of lymph - from the organs of the abdominal cavity to organ lymph nodes, and from them to the lumbar trunk and lumbar tank (Fig. 324).

Abdominal lymphadenopathy is an increase in the size of the nodes of the lymphatic system as a result of the inflammatory process in them. As a rule, lymphadenopathy is one of the manifestations of symptom complex pathologies various etiology, not an independent disease. But chronic inflammation in lymphatic nodes can lead to the development of independent pathology, which causes severe complications.
The lymphadenopathy of the abdominal cavity arises as a result of adventures with flowing lymph materials, which are caused in the tissues of lymph nodes in the abdominal cavity inflammatory response. The pathogens can be:
Implementation infectious agent The lymph nodes occurs when leaning sharp, subacute, chronic local inflammatory processes (colitis, ulcers duodenal gut etc.), less often this happens with common infectious pathologies. The pathogens fall into the lymphatic assembly of lymphogenic, hematogenic and contact paths. When injuring the lymph node, the infectious agent is possible.
The inflammatory process is protective reaction In response to the stimulus. Interacting with lymphocytes and other cells immune systemThe infectious agent causes the formation of specific substances and launches the protective mechanism. Penetrated through the gate of infection into the lymphatic assembly, the infectious agent meets sinus histiocytes. If it is not absorbed by settled macrophages, then there is a typical picture of acute inflammation.
Lymphadenopathy is accompanied by an increase in the size of the lymph nodes. However, the cause of hypertrophy is the process of node tissue hyperplasia. In the acute stage of lymphadenopathy in lymph nodes localized in the intra-abdominal area, the following processes occur:
Further progression of pathology may be accompanied by purulent separated. Depending on the time, the strength and quantities of the acting factors, the process of lymphadenopathy quickly passes all stages. As an infectious agent causing lymphadenopathy abdominal lymph nodes, agents causing:
In addition, pathological condition may be provoked by diseases connective tissue and serum pathology of medicinal nature.
Lymphadenopathy in children often accompanies cortex, rubella, vapotitis, etc. The cause of hyperplasia of intra-painted lymph nodes can become a malignant process or mesadenit - inflammation of lymph nodes in mesentery thin gut. The child is experiencing symptoms similar to acute appendicitis.
In the abdominal cavity, the lymph nodes are located along the aorta and the lower hollow vein (intricate) and near the hollow and parenchymal organs (insompector). Symptoms of pathology correspond to inflammatory process, and severity - the severity of his current.
Depending on the number of lymph nodes involved in the process, and their location, it is customary to classify lymphadenopathy on:
Generalized lymphadenopathy is the hardest, since pathological changes affect not a separate node, as under local form, and several minutes at once. Moreover, these groups can be in the unacceptably among themselves the regions of the human body. Reactive lymphadenopathy is diagnosed with a massive introduction of an infectious agent. At the same time, the symptoms are not expressed, and the increased lymph nodes are painless.
For a long time, pathology is divided into acute, chronic and recurrent. In addition, each of the above forms can take a type of tumor or non-tuch pathology. For the convenience of estimating the pathological process, some authors identify the following degrees of the increase in lymph nodes in diameter:
Parents often do not consider an increase in lymph nodes in a child an alarm signal, written off the pathology on the symptoms of viral, colds and infectious diseases. Therefore, doctors advise to conduct a survey in children often ill respiratory diseaseshaving a history of inflammation in the field of rotogling, bronchitis and croup.
The most important diagnostic sign of lymphadenopathy is the increase in the nodes of the lymphatic system. As additional symptoms of localization of pathology in the abdominal cavity can be:
The listed symptoms are not characteristic of this pathology and may mean other pathologies. In addition, additional symptoms differ depending on the type of infectious agent that caused lymphadenopathy. For example, infectious mononucleosis It causes not only the symptoms listed above, but also accompanied by such signs as the rashes of a maculopapulous nature that independently pass in 2-3 days. In the introduction of an infectious HIV agent in the initial stage, the appearance of rashes and ORZ-like symptoms is noted.
When infecting the body, the causative agent of hepatitis B, except characteristic signs, feverish phenomena, dyspeptic syndrome, jaundice are noted. Some pathogens cause symptoms of arthritis, conjunctivitis, arthralgia, urticaria, etc. With such a variety of symptom complex, diagnosis of lymphadenopathy is difficult, especially if the main symptom is not visualized, such as when localitizing the pathological process in the abdominal cavity and retroperitoneal space. If this pathology is suspected, differential studies are carried out, excluding diseases with similar symptoms.
To identify the cause of lymphadenopathy, the organization and epidemiological data is carried out. The patient is asked questions about possible blood transfusion, carrying out transplantation, random sexual relations, intravenous administration Narcotic drugs, contact with animals (cats) and birds, specific professional activity (Fishermen, hunters, farms workers and scotch, etc.), migration to foreign countries, etc.
It is of great importance to the age of the patient, since some forms of pathology are more inherent in children. The clinical examination includes a thorough palpator study of lymph nodes and determining them:
The next stage of diagnostics becomes the delivery of laboratory tests:
In addition, cytological and histological studies are appointed:
Hardware diagnostics includes:
After confirming the diagnosis and detection of the causes of the pathological process, an individual treatment scheme is developed.
Often the therapy of pathology that caused inflammation of lymph nodes leads to their decrease. In the treatment of lymphadenopathies of various etiologies, prescribe medicia treatment using:
In the treatment of lymphadenopathies in children, good indicators were noted when appointing antibacterial drugs From the group of macrolides: Roxitromycin, Josamamicina, Midekamycin. When detecting herpetic infection, acyclovir, arbidol, etc. are prescribed.
Immunomodulators are prescribed to raise immunity after the course of antibiotics, chemotherapy or radiotherapy: cycloferon, viriferon, lycopid, etc.
If drug therapy is ineffective or the cause of pathology is a malignant process, then the surgical removal of affected lymph nodes with subsequent chemotherapy courses or radiotherapy are shown. Which method to choose, solves only the attending physician, based on the history of the history, the obtained results of the diagnosis and individual characteristics of the patient. Timely identification of pathology on early stage Allows you to do without radical therapy methods.
The lymphatic system of a person is a complex plexus of special tissues and organs. Complicated anatomy reveals in front of a person some riddles of the formation of certain deviations in the course of life. Knowing the location of the lymph nodes of the retroperitoneal space and the abdominal cavity will help in understanding the causes of diseases, features of pain syndrome, which occurs when inflammation.
The system is included in the cardiovascular network. It forms a Lymph current - a substance that will distribute fluid on all tissues and organs, providing full and proper nutrition. It consists of lymphatic vessels, ducts and capillaries, as well as nodes through which fluid flows and filtered.
Lymph - "Clean Water", not having a shade. Without this fluid, it would be impossible to fully power with water tissues and useful insoluble substances. Lymph is closely related to the bloodstream, but it moves not as fast as arterial liquid.
The nodes that are included in the system are classified as immune organs, the main function of which is to protect the person through filtering of the separated liquids. In lymph nodes, immunity cells are multiplied - lymphocytes. They are responsible for the destruction of pathogenic microorganisms, bacteria, viruses. If it fails to develop this flora, severe immunodeficiency is developing, including HIV or AIDS.
In the abdominal and retroperitoneal space, as in other human body compartments, the nodes are located in one or groups. Normally, they have a pink shade and a soft structure, while retaining elasticity and a smooth shift shape. In old age, they are slightly expanding, becoming segments of segments or tarts. This is due to the merger of neighboring lymph nodes, but the pathological process is not considered.
The largest nodes of the abdominal cavity reaches size 15 mm, while small conglomerates in diameter do not exceed 0.5 mm. With age, educated groups can reach large sizes - up to 50 mm. In children, immune links are less.
The lymphatic system is located in the direction of blood vessels, it is branched off from each organ and is very extensive. At its turn, large and small nodes are located, preventing the spread of infections and the fluid cleansing fluids every minute.
There are two types of nodes: Parietal are located in the walls of the cavities, and viscerals - next to the organs. The entire system can be divided into several subgroups of nodes:
The dimensions of lymph nodes may differ, but their structure is usually identical. The situation depends on the group. The cervical elements are better than palpation. When inflammation, pain in them is determined quite accurately, and with the help of visualization you can identify an increase - additional diagnostics not required.
The lymph nodes of the abdominal cavity are more difficult to visualize and diagnose. To clarify their increase, it is necessary to ultrasound, in suspected oncological processes and other diseases can assign CT, MRI. The pain in these elements is not amenable to accurate description and is often confused with appendicitis, diseases of the stomach.
Outside, immune links covers a thin sheath consisting of connecting cells. Parenchima is the main elements of each organ of the lymphatic system. It consists of reticular cells in which there are several structures:
The cortex area includes a surface zone containing follicles, as well as a deep bark area (parakoctal). It connects the brain and cortical layer. It is in this area that the T-lymphocytes are produced necessary to combat all diseases and viruses.
From the capsule inside the node, in the parenchyma, the beams of connective tissue - Trabecules are departed. They look like small plates and partitions forming the core. In this area, the lymphatic fluid passes through the sines of the cortical and cerebral layer. The main function of these membrane membrane membranes is cleaning water from foreign elements.
The structure of the protective links is not characterized by tremendous complexity, but the slightest failure in it is able to lead to severe autoimmune processes. Damage to filtering membranes - the path to the development of deaths for the human immunodeficiency.
To facilitate the diagnosis, treatment and study of the lymphatic system, all nodes in the abdominal cavity are divided into several subgroups:
Each node has a unique feature that is responsible for cleansing the liquids entering a nearby organ or structure. If a person suffers from a disease, for example, a stomach, then the gastric nodes are inflated primarily. But with a long and acute course of the disease, the defeat of remote links is possible.
Parapoortal lymph nodes located in the abdominal cavity near the stomach, intestines and pancreas are most often exposed to the growth of cancer cells. They detect metastases. Parapoortal nodes may appear pathological formations emanating from prostate, ovaries, uterus, bladder.
If the size of the lymphatic element increases, this indicates the development of the disease and inflammation. The pathological process may begin with the active development of lymphocytes, which is associated with the activation of the immune system to combat the body's disease located nearby. An increase in protective links is characteristic of a variety of diseases and infections:
It is impossible to determine only by the state of the nodes. To confirm the diagnosis, a number of surveys are assigned.
An increase in lymph nodes is never spontaneous and requires the close attention of doctors. This condition does not always hide dangerous and incurable diseases. Timely examination helps to identify statiya Violations and quickly eliminate it.
In addition to ultrasound and MRI in suspected infection, viruses and oncological processes are prescribing additional examination methods:
Deciphering received data is engaged in the attendance - oncologist, infectious player, surgeons, or all specialists together.
