肠道微生态影响动脉粥样硬化发生发展的机制

动脉粥样硬化(AS)不仅是一种炎症性疾病,而且属于一种代谢性疾病。肠道微生态的改变可对AS的发生发展产生双面影响。一方面,肠道菌群紊乱可以通过影响机体的胆碱代谢、氧化应激、炎症反应等机制直接促进AS产生发展,此外,可通过导致AS危险因素肥胖、高脂血症、糖尿病等的产生这些间接机制促AS的进展。另一方面,益生菌及益生元的增加则可有效地降低肠道微生物内毒素产生、增强肠道屏障、减轻机体质量、缓解炎症反应、改善胰岛素抵抗,进而在AS的进展方面发挥重要作用。因此,合理调控机体肠道微生态环境成为AS防治的新型重要手段。     

PNPLA3 I148M polymorphism and progressive liver disease

The 148 Isoleucine to Methionine protein variant(I148M)of patatin-like phospholipase domain-containing 3(PNPLA3),a protein is expressed in the liver and is involved in lipid metabolism,has recently been identified as a major determinant of liver fat content.Several studies confirmed that the I148M variant predisposes towards the full spectrum of liver damage associated with fatty liver:from simple steatosis to steatohepatitis and progressive fibrosis.Furthermore,the I148M variant represents a major determinant of progression of alcohol related steatohepatitis to cirrhosis,and to influence fibrogenesis and related clinical outcomes in chronic hepatitis C virus hepatitis,and possibly chronic hepatitis B virus hepatitis,hereditary hemochromatosis and primary sclerosing cholangitis.All in all,studies suggest that the I148M polymorphism may represent a general modifier of fibrogenesis in liver diseases.Remarkably,the effect of the I148M variant on fibrosis was independent of that on hepatic steatosis and inflammation,suggesting that it may affect both the quantity and quality of hepatic lipids and the biology of non-parenchymal liver cells besides hepatocytes,directly promoting fibrogenesis.Therefore,PNPLA3 is a key player in liver disease progression.Assessment of the I148M polymorphism will possibly inform clinical practice in the future,whereas the determination of the effect of the 148M variant will reveal mechanisms involved in hepatic fibrogenesis.     

Endoscopic resection techniques for colorectal neoplasia:Current developments

Endoscopic polypectomy and endoscopic mucosal resection(EMR) are the established treatment standards for colorectal polyps. Current research aims at the reduction of both complication and recurrence rates as well as on shortening procedure times. Cold snare resection is the emerging standard for the treatment of smaller(< 5 mm) polyps and is possibly also suitable for the removal of noncancerous polyps up to 9 mm. The method avoids thermal damage, has reduced procedure times and probably also a lower risk for delayed bleeding. On the other end of the treatment spectrum, endoscopic submucosal dissection(ESD)offers en bloc resection of larger flat or sessile lesions. The technique has obvious advantages in the treatment of high-grade dysplasia and early cancer. Due to its minimal recurrence rate, it may also be an alternative to fractionated EMR of larger flat or sessile lesions. However, ESD is technically demanding and burdened by longer procedure times and higher costs. It should therefore be restricted to lesions suspicious for high-grade dysplasia or early invasive cancer.The latest addition to endoscopic resection techniques is endoscopic fullthickness resection with specifically developed devices for flexible endoscopy.This method is very useful for the treatment of smaller difficult-to-resect lesions,e.g., recurrence with scar formation after previous endoscopic resections.     

Lymph node staging in colorectal cancer:Old controversies and recent advances

Outcome prediction based on tumor stage reflected by the American Joint Committee on Cancer(AJCC)/Union for International Cancer Control(UICC)tumor node metastasis(TNM)system is currently regarded as the strongest prognostic parameter for patients with colorectal cancer.For affected patients,the indication for adjuvant therapy is mainly guided by the presence of regional lymph node metastasis.In addition to the extent of surgical lymph node removal and the thoroughness of the pathologist in dissecting the resection specimen,several parameters that are related to the pathological work-up of the dissected nodes may affect the clinical significance of lymph node staging.These include changing definitions of lymph nodes,involved lymph nodes,and tumor deposits in different editions of the AJCC/UICC TNM system as well as the minimum number of nodes to be dissected.Methods to increase the lymph node yield in the fatty tissue include methylene blue injection and acetone compression.Outcome prediction based on the lymph node ratio,defined as the number of positive lymph nodes divided by the total number of retrieved nodes,may be superior to the absolute numbers of involved nodes.Extracapsular invasion has been identified as additional prognostic factor.Adding step sectioning and immunohistochemistry to the pathological work-up may result in higher accuracy of histological diagnosis.The clinical value of more recent technical advances,such as sentinel lymph node biopsy and molecular analysis of lymph nodes tissue still remains to be defined.     

Role of endoscopic ultrasound in the screening and follow-up of high-risk individuals for familial pancreatic cancer

Managing familial pancreatic cancer(FPC)is challenging for gastroenterologists,surgeons and oncologists.High-risk individuals(HRI)for pancreatic cancer(PC)(FPC or with germline mutations)are a heterogeneous group of subjects with a theoretical lifetime cumulative risk of PC over 5%.Screening is mainly based on annual magnetic resonance imaging(MRI)and endoscopic ultrasound(EUS).The goal of screening is to identify early-stage operable cancers or high-risk precancerous lesions(pancreatic intraepithelial neoplasia or intraductal papillary mucinous neoplasms with high-grade dysplasia).In the literature,target lesions are identified in 2%-5%of HRI who undergo screening.EUS appears to provide better identification of small solid lesions(0%-46%of HRI)and chronicpancreatitis-like parenchymal changes(14%-77%of HRI),while MRI is probably the best modality to identify small cystic lesions(13%-49%of HRI).There are no specific studies in HRI on the use of contrast-enhanced harmonic EUS.EUS can also be used to obtain tissue samples.Nevertheless,there is still limited evidence on the accuracy of imaging procedures used for screening or agreement on which patients to treat.The cost-effectiveness of screening is also unclear.Certain new EUS-related techniques,such as searching for DNA abnormalities or protein markers in pancreatic fluid,appear to be promising.     

Prophecy about post-endoscopic retrograde cholangiopancreatography pancreatitis:From divination to science

One unresolved issue of endoscopic retrograde cholangiopancreatography(ERCP)is post-ERCP pancreatitis (PEP),which occurs in up to 40%of patients.Identification of risk factors for PEP is especially important in the field of ERCP practice because it may assist physicians in taking protective measures in situations with high risk.A decade ago,Freeman et al meticulously evaluated a large number of potentially relevant risk factors for PEP,which can be divided into patient-relat-ed and procedure-related issues.In this commentary, we summarize this classic article and reevaluate the risk factors for PEP from the current point of view.This is followed by assessment of strategies for prevention of PEP that can be divided into mechanical and pharmacologic methods.     

Issues and controversies in esophageal inlet patch

The proximal esophagus is rarely examined,and its inspection is often inadequate.Optical chromoendoscopy techniques such as narrow band imaging improve the detection rate of inlet patches in the proximal esophagus,a region in which their prevalence is likely underestimated.Various studies have reported correlations between these esophageal marks with different issues such as Barrett’s esophagus,but these findings remain controversial.Conflicting reports complicate the process of interpreting the clinical features of esophageal inlet patches and underestimate their importance.Unfortunately,the limited clinical data and statistical analyses make reaching any conclusions difficult.It is hypothesized that inlet patches are correlated with various esophageal and extraesophageal symptoms,diagnoses and the personalized therapeutic management of patients with inlet patches as well as the differential diagnosis for premalignant lesions or early cancers.Due to its potential underdiagnosis,there are no consensus guidelines for the management and follow up of inlet patches.This review focuses on questions that were raised from published literature on esophageal inlet patches in adults.     

Endoscopic management of difficult common bile duct stones

Endoscopy is widely accepted as the first treatment option in the management of bile duct stones.In this review we focus on the alternative endoscopic modalities for the management of difficult common bile duct stones.Most biliary stones can be removed with an extraction balloon,extraction basket or mechanical lithotripsy after endoscopic sphincterotomy.Endoscopic papillary balloon dilation with or without endoscopic sphincterotomy or mechanical lithotripsy has been shown to be effective for management of difficult to remove bile duct stones in selected patients.Ductal clearance can be safely achieved with peroral cholangioscopy guided laser or electrohydraulic lithotripsy in most cases where other endoscopic treatment modalities have failed.Biliary stenting may be an alternative treatment option for frail and elderly patients or those with serious co morbidities.     

Rare cystic liver lesions: A diagnostic and managing challenge

Cystic formations within the liver are a frequent finding among populations.Besides the common cystic lesions,like simple liver cysts,rare cystic liver lesions like cystadenocarcinoma should also be considered in the differential diagnosis.Thorough knowledge of each entity’s nature and course are key elements to successful treatment.Detailed search in PubMed,Cochrane Database,and international published literature regarding rare cystic liver lesions was carried out.In our research are included not only primary rare lesions like cystadenoma,hydatid cyst,and polycystic liver disease,but also secondary ones like metastasis from gastrointestinal stromal tumors lesions.Up-to date knowledge regarding diagnosis and management of rare cystic liver lesions is provided.A diagnostic and therapeutic algorithm is also proposed.The need for a multidisciplinary approach by a team including radiologists and surgeons familiar with liver cystic entities,diagnostic tools,and treatment modalities is stressed.Patients with cystic liver lesions must be carefully evaluated by a multidisciplinary team,in order to receive the most appropriate treatment,since many cystic liver lesions have a malignant potential and evolution.     

Endoscopy and polyps-diagnostic and therapeutic advances in management

Despite multiple efforts aimed at early detection through screening, colon cancer remains the third leading cause of cancer-related deaths in the United States, with an estimated 51000 deaths during 2013 alone. The goal remains to identify and remove benign neoplastic polyps prior to becoming invasive cancers. Polypoid lesions of the colon vary widely from hyperplastic, hamartomatous and inflammatory to neoplastic adenomatous growths. Although these lesions are all benign, they are common, with up to one-quarter of patients over 60 years old will develop pre-malignant adenomatous polyps. Colonoscopy is the most effective screening tool to detect polyps and colon cancer, although several studies have demonstrated missed polyp rates from 6%-29%, largely due to variations in polyp size. This number can be as high as 40%, even with advanced (> 1 cm) adenomas. Other factors including sub-optimal bowel preparation, experience of the endoscopist, and patient anatomical variations all affect the detection rate. Additional challenges in decision-making exist when dealing with more advanced, and typically larger, polyps that have traditionally required formal resection. In this brief review, we will explore the recent advances in polyp detection and therapeutic options.     

Three layer functional model and energy exchange concept of aging process

Relying on a certain degree of abstraction, we can propose that no particular distinction exists between animate or living matter and inanimate matter. While focusing attention on some specifics, the dividing line between the two can be drawn. The most apparent distinction is in the level of structural and functional organization with the dissimilar streams of ‘energy flow’ between the observed entity and the surrounding environment. In essence, living matter is created from inanimate matter which is organized to contain internal intense energy processes and maintain lower intensity energy exchange processes with the environment. Taking internal and external energy processes into account, we contend in this paper that living matter can be referred to as matter of dissipative structure, with this structure assumed to be a common quality of all living creatures and living matter in general. Interruption of internal energy conversion processes and terminating the controlled energy exchange with the environment leads to degeneration of dissipative structure and reduction of the same to inanimate matter, (gas, liquid and/or solid inanimate substances), and ultimately what can be called ‘death.’ This concept of what we call dissipative nature can be extended from living organisms to social groups of animals, to mankind. An analogy based on the organization of matter provides a basis for a functional model of living entities. The models relies on the parallels among the three central structures of any cell (nucleus, cytoplasm and outer membrane) and the human body (central organs, body fluids along with the connective tissues, and external skin integument). This three-part structural organization may be observed almost universally in nature. It can be observed from the atomic structure to the planetary and intergalactic organizations. This similarity is corroborated by the membrane theory applied to living organisms. According to the energy nature of living matter and the proposed functional model, the decreased integrity of a human body's external envelope membrane is a first cause of the structural degradation and aging of the entire organism. The aging process than progresses externally to internally, as in single cell organisms, suggesting that much of the efforts towards the restoration and maintenance of the mechanisms responsible for structural development should be focused accordingly, on the membrane, i.e., the skin. Numerous reports indicate that all parts of the human body, like: bones, blood with blood vessels, muscles, skin, and so on, have some ability for restoration. Therefore, actual revival of not only aging tissue of the human body's membrane, but the entire human body enclosed within, with all internal organs, might be expected. We assess several aging theories within the context of our model and provide suggestions on how to activate the body's own anti-aging mechanisms and increase longevity. This paper presents some analogies and some distinctions that exist between the living dissipative structure matter and inanimate matter, discusses the aging process and proposes certain aging reversal solutions.     

Lack of correlation of anorectal manometry with symptoms of chronic childhood constipation and encopresis

Chronic constipation is an extremely common problem in children. Many authors have advocated using anorectal manometric examination during evaluation of chronic childhood constipation and encopresis as a means of developing individualized modes of treatment. PURPOSE: This study was designed to prospectively examine frequency and severity of symptoms of childhood constipation and encopresis and associate these symptoms with anorectal manometric findings. METHODS: Forty-four children with chronic constipation participated in the study. Before performing anorectal manometry, bowel-related symptoms were collected for two consecutive weeks with a computerized voice mail system. Anorectal manometry was performed using a triple lumen catheter attached to a hydraulic manometry infusion system. RESULTS: Frequency of voluntary bowel movements did not correlate with any manometric parameters. Frequency of fecal soiling, age at onset of symptoms, and duration of symptoms were all highly correlated with degree of sphincter spasm during attempted defecation; however, none of these variables correlated with any other manometric parameter. Amount of pain associated with bowel movements correlated with frequency of soiling and was inversely correlated with maximum squeeze pressure but was not correlated with any other manometric parameter. CONCLUSIONS: In children with chronic constipation and encopresis, sphincter spasm demonstrated with anorectal manometry is highly correlated with frequency of fecal soiling, age at onset, and duration of symptoms; however, none of the other commonly measured manometric parameters appear to correlate with symptoms of chronic childhood constipation and encopresis.Supported by National Institutes of Health Grant RO1 HD 28160.     

Aortite et complications aortiques de l’artérite à cellules géantes (maladie de Horton)

Aortitis is a serious complication of giant cell arteritis (GCA), because of the risk of aortic aneurism, rupture, or dissection. Aortitis is present either at presentation or, more frequently, occurs as a delayed complication, typically as an aortic aneurism of the ascending part of the aorta. An aortic aneurism may occur in up to 10% of patients. Aortitis is sometimes associated to arteritis of the supra-aortic vessels. Risk factors for aortitis remain unknown. Recent clinical studies indicate that prevalence of aortitis was initially under-estimated. Imaging studies show signs of infra-clinical aortitis in 20 to 65% of cases at diagnosis. Using ultrasonography, thickening of the vascular wall with an hypoechoic halo around the abdominal aorta is suggestive of abdominal aortitis. Positron emission tomography shows a metabolic hypersignal of the aorta in about 50% of patients with giant cell arteritis. Aortic computed tomographic (CT) scan visualizes aneurysmal dilatations, ectasia or focal or concentric parietal thickenings. When present at the time of diagnosis of GCA, these findings seem to be associated with frequent relapses and perhaps with a higher long-term vascular mortality rate. Therefore, we recommend the screening of aortitis lesions at GCA diagnosis by an aortic CT-scan and follow-up. Therapeutic trials should be conducted to try to improve the treatment of aortitis in GCA.     

The immunoneuroendocrine role of melatonin

Abstract: A tight, physiological link between the pineal gland and the immune system is emerging from a series of experimental studies. This link might reflect the evolutionary connection between self-recognition and reproduction. Pinealectomy or other experimental methods which inhibit melatonin synthesis and secretion induce a state of immunodepression which is counteracted by melatonin. In general, melatonin seems to have an immunoenhancing effect that is particularly apparent in immunodepressive states. The negative effect of acute stress or immunosuppressive pharmacological treatments on various immune parameters are counteracted by melatonin. It seems important to note that one of the main targets of melatonin is the thymus, i.e., the central organ of the immune system. The clinical use of melatonin as an immunotherapeutic agent seems promising in primary and secondary immunodeficiencies as well as in cancer immunotherapy. The immunoenhancing action of melatonin seems to be mediated by T-helper cell-derived opioid peptides as well as by lymphokines and, perhaps, by pituitary hormones. Melatonin-induced-immuno-opioids (MHO) and lymphokines imply the presence of specific binding sites or melatonin receptors on cells of the immune system. On the other hand, lymphokines such as -γ-interferon and interleukin-2 as well as thymic hormones can modulate the synthesis of melatonin in the pineal gland. The pineal gland might thus be viewed as the crux of a sophisticated immunoneuroendocrine network which functions as an unconscious, diffuse sensory organ.     

Vaginography—Investigation of choice for clinically suspected vaginal fistulas

PURPOSE: Vaginal fistulas are rare but can cause extremely distressing symptoms for patients and prove difficult to define anatomically. Barium studies have been reported as having a maximum sensitivity of only 34 percent for detection of vaginal fistulas. Vaginography is an alternative method for diagnosis and evaluation of suspected vaginal fistulas, which has been reported to have a sensitivity of 100 percent. We reviewed our total experience of vaginography to fully assess its capabilities. METHODS: Twenty-seven patients with clinically suspected vaginal fistulas were investigated with vaginography during a six-year period. Results of vaginograms were compared with final operative or clinical diagnosis and with results of other radiologic investigations. RESULTS: Vaginography successfully identified 19 of 24 fistulas, giving a sensitivity of 79 percent. In our series, barium enema was only able to identify 9 percent of fistulas arising from the colon. CONCLUSIONS: In this, the largest series of vaginograms, apparent reduction in sensitivity from the 100 percent quoted in earlier series to 79 percent probably represents a more accurate assessment of vaginography as a diagnostic investigation. Even allowing for this reduction, vaginography is still the most sensitive, economic, and informative investigation for identification and delineation of vaginal fistulas. We recommend that vaginography be the initial investigation of choice in patients with clinically suspected vaginal fistulas.Mr. Drew was supported by a Yorkshire Health Research Fellowship.Poster presentation at the meeting of The American Society of Colon and Rectal Surgeons, Montreal, Quebec, Canada, May 7 to 12, 1995.     

Morphological and immunocytochemical heterogeneity of cultured pinealocytes from one-week-and two-month-old rats: Planimetric and densitometric investigations

Abstract: In vitro preparations of rat pinealocytes are widely used for biochemical analyses of signal transduction processes. This paper deals with morphological and immunocytochemical features of such preparations. Special attention was paid to the problems of whether pinealocytes represent a heterogeneous cell population and how such heterogeneity may develop during ontogeny. The investigations were performed with cells which were obtained from the pineal organ of one-week-and two-month-old rats, attached to synthetic peptide-coated coverslips or tissue culture chamber slides, and maintained under in vitro conditions overnight. The attached cells were then fixed with paraformaldehyde. These preparations yielded monolayers of spherical cells of different sizes; most cells were isolated, but some of them were aggregated and formed small clusters. On the average, the cells from the one-week-old animals were smaller than the cells from the two-month-old animals. Immunocytochemical demonstration of S-antigen, a pinealocyte-specific marker, showed that the majority of the cells from two-month-old animals were intensely or moderately labelled. Pinealocytes from one-week-old animals were less S-antigen immunoreactive. Only very few cells (less than 1% displayed glial fibrillary acidic protein (GFAP)-immunoreactivity. Planimetric investigations of the cell size and semiquantitative densitometric investigations of the intensity of the S-antigen immunoreaction revealed that (i) pinealocytes kept in vitro form a heterogeneous cell population, and that (ii) this heterogeneity increases during postnatal development from one-week-old to two-month-old animals. Two groups of pinealocytes can be distinguished based on their developmental fate: pinealocytes of one group grow dramatically, but show only a moderate increase in S-antigen immunoreactivity, and pinealocytes of the other group retain their size, but display a distinct increment in S-antigen immunoreacti vitv.     

Lysis and immobilization of Giardia murk trophozoites in vitro by immune serum from susceptible and resistant mice

To define the potential role of antibody in host defence against Giardia muris, comparative assessment of in-vitro anti-trophozoite effects of immune serum obtained from susceptible (A/J) and resistant (B10.A) mice was done. Two anti-parasite effects of serum were identified and quantified: lysis and immobilization of trophozoites. These giardicidal activities were present in the serum from both A/J and B10.A mice. Maximal lysis of trophozoites by serum from A/J or B10.A mice was 40 to 50%. The lysis of trophozoites was abolished after incubation of serum at 56 degrees C for 30 min. The addition of exogenous complement restored lytic activity of heat-inactivated serum. The immobilization of trophozoites was dependent on both the duration of incubation and concentration of serum. After 30 min of incubation, over 98% of trophozoites were immobilized by immune serum from A/J or B10.A mice. There was no apparent relationship between the capacity of immune sera from A/J and B10.A mice to kill trophozoites in vitro and the ability of these strains of mice to control the infection with G. muris.     

Réflexes autonomiques cardiovasculaires dans le syndrome de tachycardie orthostatique idiopathique

Postural orthostatic tachycardia syndrome (POTS) is a badly known pathology because its diagnosis is not based on the conventional methods of investigation. The orthostatic test allows to make the diagnosis easily. The objective of this study is to determine cardiovascular autonomic reflexes of 70 patients having POTS. The tests of exploration of the autonomic nervous system practised are: deep breathing, hand grip, mental stress and orthostatic test. The analysis of orthostatic test showed that the increase of the cardiac frequency, relative to the state of “β” peripheral sympathetic hyperactivity occurred before the 2nd minute in 80% of patients. The POTS was considered “florid” in 43% of patients and had complicated of a rough and severe fall of systolic blood pressure inferior to 70 mmHg in four patients, after the fifth minute of the test. The analysis of the different tests had shown vagale hyperactivity in 63% of patients on deep breathing, in 93% of patients on hand grip and in 100% on orthostatic test. The “α” central sympathetic activity was increased in 76% of the cases and “β” central sympathetic activity was high in 83% of cases. The “α” peripheral hyperactivity was observed in 63% of patients on hand grip, and in 44% on orthostatic test. The analysis of cardiovascular autonomic reflexes on patients affected by POTS allowing the determination of their autonomic profile, will contribute probably to a better understanding of this pathology and to a better orientation of its care.     

Colonoscopic follow-up of colorectal carcinoma

PURPOSE: The value of routine colonoscopy in the prevention or early detection of metachronous carcinoma of the colon and rectum remains unproven. This study attempts to clarify this issue. METHODS: An analysis of a personal series of 460 patients with primary colorectal carcinoma treated by the second author between 1972 and 1990 was reviewed. After various exclusions, there remained 231 patients who had been prospectively followed by colonoscopy with a mean follow-up period of 56 years. RESULTS: In 48 (21 percent) patients, there were synchronous adenomas present at the time of the initial resection for carcinoma and 35 (73 percent) of these patients subsequently developed metachronous adenomas, being recurrent in 22. Ninety-five (52 percent) of the 183 patients without synchronous adenomas eventually developed metachronous adenomas, so that overall 130 (56 percent) patients developed metachronous adenomas. Four patients developed a metachronous carcinoma that was either Dukes A or B, and all remain well at the time of final follow-up. These metachronous carcinomas were found after a mean interval of seven and three-quarter years. All four patients had synchronous adenomas and all developed metachronous adenomas on multiple occasions before the metachronous carcinoma was detected. Thus, a subset consisting of only 22 patients produced all four metachronous malignancies—a rate of 18 percent. CONCLUSION: It would appear that the presence of synchronous adenomas with the subsequent development of recurring metachronous adenomas is significant and warrants a more intensive follow-up program to ensure the early diagnosis and more likely cure of any metachronous carcinoma.Read at the Tripartite Colorectal Meeting, Sydney, Australia, October 17 to 20, 1993.     

Panniculite mésentérique

Mesenteric panniculitis is a nonspecific inflammatory process affecting the fatty tissue at the root of the mesentery. This term is also used to describe the clinical and imaging findings in this disorder. Mesenteric panniculitis can be a misleading term: it is commonly misused to design an increased density of the mesentery without prejudice regarding the etiology. Pain is the main clinical symptom. Half of the patients are asymptomatic. There is a palpable mass in half of cases. Laboratory tests sometimes reveal an acute phase reaction of varying intensity. Mesenteric panniculitis is suspected when CT scan shows increased density of the mesenteric fat. Nevertheless, only histological examination could establish the diagnosis. Histologic examination may reveal various stages: lipodystrophy (the first stage when fat necrosis is predominant), mesenteric panniculitis (a majority of infiltrating lymphocytes), sclerosing mesenteritis (the end stage when fibrosis is predominant). Histopathologic differential diagnoses are lymphomas, lipomas, liposarcomas that can mimic mesenteric panniculitis on CT scan. Mesenteric panniculitis is associated with various diseases, especially with intra-abdominal inflammatory process. It also can be idiopathic. Rare complications can occur with vascular or digestive tract compressions. Empirical treatment is only useful in symptomatic patients. Colchicine, corticosteroids or immunosuppressive agents can be used. The only interest of surgery is the histological confirmation of the diagnosis. A better understanding of the pathophysiology of the immunoregulatory functions of adipose tissue will improve mesenteric panniculitis management.
