Nandrolone decanoate impairs gastrointestinal motility and duodenal morphometry in moderately exercised rats.

The misuse of anabolic androgenic steroid associated or not with physical workouts disrupts gastrointestinal (GI) function homeostasis. Our goal was to investigate the effects of nandrolone decanoate (ND) and moderate swimming on the GI transit of solid meals, GI motor contractility, and intestinal histology in rats. Male Wistar rats were allocated to four groups that received intramuscular injections of ND (5.0 mg/kg) or vehicle (60.0 µL) and were submitted or not to swimming sessions (60 min, 5% body weight overload) for 4 weeks. Gastric emptying, intestinal transit, in vitro GI contractility, intestinal morphometry, and duodenal mucosal mast cells were evaluated in all experimental groups. ND treatment accelerated gastric emptying, slowed small intestine transit time, enhanced gastric carbachol-mediated reactivity, decreased crypt depth and villus height, reduced mucosal thickness, and increased the circular and longitudinal muscle layer thickness of the duodenum in sedentary rats. Moderate exercise accelerated intestinal transit time and reduced submucosa thickness. In vehicle-treated animals, a strong negative correlation was found between intestinal transit and mucosal mast cells, which was reversed by ND treatment. Combining ND treatment and swimming accelerated gastric emptying, increased duodenal cholinergic reactivity, inhibited the sodium nitroprusside relaxing response, increased the number of duodenal mast cells, decreased villus height, and increased the thickness of all muscle layers. ND changed the morphological and functional properties of the GI tract over time, with intense dysmotility, especially in sedentary animals, but moderate exercise seemed to have played a compensatory role in these harmful effects in the gut.

Síndrome de la arteria mesentérica superior (Síndrome de Wilkie): A propósito de un caso en una adolescente / Superior mesenteric artery syndrome (Wilkie syndrome): A case report in an adolescent

Introducción. El síndrome de la arteria mesentérica superior, también conocido como síndrome de Wilkie, es una entidad infrecuente en la que una reducción del ángulo o espacio aorto-mesentérico determina una compresión extrínseca con obstrucción del tercio distal del duodeno, demostrando síntomas y signos característicos de obstrucción intestinal. El pilar del tratamiento es el manejo médico conservador con repleción nutricional, con el objetivo de aumentar el grosor de la grasa retroperitoneal y con esto resolver la compresión duodenal. Caso clínico. Paciente de 16 años, con un curso crónico marcado por dolor abdominal, estreñimiento, distensión, pirosis y pérdida de peso. Inicialmente se trató como una enfermedad ácido-péptica, con pobre mejoría, por lo que se realizaron estudios imagenológicos con lo que se documentó una disminución del ángulo aortomesentérico. Resultado. Se instauró un manejo médico con un protocolo de repleción nutricional por vía oral, para lograr ganancia de peso y evitar la cirugía. Conclusión. Con base a los síntomas y hallazgos en imágenes diagnósticas se hizo el diagnóstico de síndrome de la arteria mesentérica superior, que es una causa de obstrucción intestinal con muy baja incidencia. Su presentación clínica incluye gran variedad de síntomas, entre los que destaca el dolor abdominal y la pérdida de peso. Es frecuente la confusión con otras enfermedades más frecuentes, como enfermedad ácido-péptica, reflujo gastrointestinal y malabsorción. Su diagnóstico requiere un alto índice de sospecha, por lo que es importante conocer esta entidad y considerarla en el estudio de pacientes con los síntomas mencionados.

Introduction. Superior mesenteric artery syndrome, also known as Wilkie syndrome, is a rare entity in which a reduction in the aorto-mesenteric angle or space determines extrinsic compression with obstruction of the distal third of the duodenum, demonstrating characteristic symptoms and signs of intestinal obstruction. The mainstay of treatment is conservative medical management with nutritional repletion, with the aim of increasing the thickness of the retroperitoneal fat and thereby resolving duodenal compression. Clinical case. A 16-year-old patient, with a chronic course marked by abdominal pain, constipation, bloating, heartburn and weight loss. Initially was treated as an acid-peptic disease, with poor improvement. Imaging studies were performed, which documented a decrease in the aorto-mesenteric angle. Conclusion. Based on the symptoms and findings on diagnostic images, the diagnosis of superior mesenteric artery syndrome was made, which is a cause of intestinal obstruction with a very low incidence. Its clinical presentation includes a wide variety of symptoms, among which abdominal pain and weight loss stand out. Confusion with other more common diseases is common, such as acid-peptic disease, gastrointestinal reflux and malabsorption. Its diagnosis requires a high index of suspicion, so it is important to know this entity and consider it in the study of patients with the aforementioned symptoms.

In situ interaction of pea peptides and bile salts under in vitro digestion: Potential impact on lipolysis.

The present work evaluated how a native pea protein isolate (PPI) affects the key roles carried out by bile salts (BS) in lipid digestion by means of the in vitro static INFOGEST protocol. Two gastric residence times were evaluated (10 and 60 min), and then the peptides obtained (GPPP) were mixed with BS at physiological concentration in simulated intestinal fluid to understand how they interact with BS both at the bulk and at the interface. Both GPPP give rise to a film with a predominant viscous character that does not constitute a barrier to the penetration of BS, but interact with BS in the bulk duodenal fluid. When the peptides flushing from the stomach after the different gastric residence times undergo duodenal digestion, it was found that for the longer gastric residence time the percentage of soluble fraction in the duodenal phase, that perform synergistically with BS micelles, was twice that of the lower residence time, leading to an increase in the solubilization of oleic acid. These results finally lead to a greater extent of lipolysis of olive oil emulsions. This work demonstrates the usefulness of in vitro models as a starting point to study the influence of gastric residence time of pea protein on its interaction with BS, affecting lipolysis. Pea proteins were shown to be effective emulsifiers that synergistically perform with BS improving the release and bioaccessibility of bioactive lipids as olive oil.

Unveiling a Silent Obstructor: Phytobezoar in the Third Duodenal Segment.

We present a case of obstruction in the third portion of the duodenum secondary to a phytobezoar in an adult patient with no surgical history and without a vegan diet. High intestinal obstruction due to a phytobezoar is rarely described in the literature, posing a diagnostic challenge when evaluating potential differentials in the emergency setting. Subsequently, we conduct a review focusing on tomographic findings and the surgical specimen, highlighting key points to consider when addressing such pathologies.

Duodenal mucosa of untreated celiac disease patients has altered expression of the GAS6 and PROS1 and the negative regulator tyrosine kinase TAM receptors subfamily.

Celiac disease (CD) is an immune-driven disease characterized by tissue damage in the small intestine of genetically-susceptible individuals. We evaluated here a crucial immune regulatory pathway involving TYRO3, AXL, and MERTK (TAM) receptors and their ligands PROS1 and GAS6 in duodenal biopsies of controls and CD patients. We found increased GAS6 expression associated with downregulation of PROS1 and variable TAM receptors levels in duodenum tissue of CD patients. Interestingly, CD3+ lymphocytes, CD68+, CD11c+ myeloid and epithelial cells, showed differential expressions of TAM components comparing CD vs controls. Principal component analysis revealed a clear segregation of two groups of CD patients based on TAM components and IFN signaling. In vitro validation demonstrated that monocytes, T lymphocytes and epithelial cells upregulated TAM components in response to IFN stimulation. Our findings highlight a dysregulated TAM axis in CD related to IFN signaling and contribute to a deeper understanding of the pathophysiology of CD.

Morphological Characteristics of the Results of Experimental Modeling of Septic Peritonitis

SUMMARY: Experimental studies devoted to the study of the mechanisms of the pathogenesis of acute peritonitis and the development of new methods of medical and surgical treatment are becoming increasingly relevant. Today, experimental medicine knows many different ways to modeling septic peritonitis and eliminate it, but the role of the local immune system is underestimated, whereas it takes a direct part in inflammation. The objective of our work to study morphological features of results of experimental modeling of septic peritonitis in white rats. The study included 15 sexually mature white male rats weighing 276.75±6.56 grams. A simulation of septic peritonitis was performed by perforating the upper part of the cecum with four punctures with a G16 injection needle. As a result of the experiment, after examination of the peritoneal cavity, all 15 animals were diagnosed with omentum tamponade of perforated damage to the caecum. In 11 cases, the perforated wall of the caecum was covered by the greater omentum (73.34 %), and in the other 4 animals, tamponade was performed by one of the epididymal omentum (26.66 %). The initial stage of tamponade with the greater or epididymal omentums of a perforated caecum begins on the first day of the experiment and consists of tight interstitial consolidation between them, as well as in the invasion of blood vessels from the omentum side to the focus of infection, which ensure the delivery of the appropriate immunocompetent cells. As a result of this process, intensive lymphoid infiltrates are formed in this area, as well as the growth of adipose tissue, which isolates the inflammatory focus from the peritoneal cavity with a thick layer.

Las investigaciones experimentales dedicadas al estudio de los mecanismos de patogénesis de la peritonitis aguda y el desarrollo de nuevos métodos de tratamiento médico y quirúrgico son cada vez más relevantes. Hoy en día, la medicina experimental conoce muchas formas diferentes de modelar la peritonitis séptica y eliminarla, pero se subestima el papel del sistema inmunológico local, mientras que él participa directamente en la inflamación. El objetivo de nuestro trabajo fue estudiar las características morfológicas de los resultados del modelado experimental de peritonitis séptica en ratas blancas. El estudio incluyó 15 ratas macho blancas, sexualmente maduras que pesaban 276,75 ± 6,56 gramos. Se realizó una simulación de peritonitis séptica perforando la parte superior del ciego con cuatro punciones con una aguja de inyección G16. Como resultado del experimento, después del examen de la cavidad peritoneal, a los 15 animales se les diagnosticó taponamiento del omento o lesión perforada del ciego. En 11 casos, la pared perforada del ciego fue recubierta por el omento mayor (73,34 %), y en los otros 4 animales el taponamiento se realizó por uno de los epidídimos (26,66 %). La etapa inicial del taponamiento con omento mayor o epidídimo de un ciego perforado comienza el primer día del experimento y consiste en una estrecha consolidación intersticial entre ellos, así como en la invasión de los vasos sanguíneos desde el lado del omento hasta el foco de infección, que aseguran la entrega de las células inmunocompetentes apropiadas. Como resultado de este proceso, se forman intensos infiltrados linfoides en esta zona, así como el crecimiento de tejido adiposo, que aísla el foco inflamatorio de la cavidad peritoneal con una gruesa capa.

PARTIAL DISTAL DUODENECTOMY IN PATIENT WITH ADENOCARCINOMA.

BACKGROUND: Duodenal adenocarcinoma is a small percentage of gastrointestinal neoplasms, around 0.5%, and its treatment is based on resection of the tumor, classically by pancreaticoduodenectomy. In recent years, however, segmental resections of duodenal lesions, that do not involve the second portion or the periampullary region, have gained relevance with good surgical and oncological outcomes as well as the benefit of avoiding surgeries that can result in high morbidity and mortality. AIMS: To report a case of an elderly female patient with malignant neoplastic lesion in the third and fourth duodenal portion, non-obstructive, submitted to surgical treatment. METHODS: The technical option was the resection of the distal duodenum and proximal jejunum with preservation of the pancreas and reconstruction with side-to-side duodenojejunal anastomosis. RESULTS: The evolution was satisfactory and the surgical margins were free of neoplasia. CONCLUSIONS: Segmental resections of the duodenum are feasible and safe, offering the benefit of preventing complications of pancreaticoduodenectomies.

Management of post-ERCP duodenal perforations: experience at Hospital Juárez de México.

BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) is an endoscopic study in which the duodenum is observed laterally, and the bile duct is instrumented. There are several indications and complications in the procedure. OBJECTIVE: To determine the incidence of duodenal perforations, using the Stapfer classification in the Hospital Juárez de Mexico over a period of 5 years, as well as the management implemented in such cases. METHOD: The study was carried out at the Hospital Juárez de Mexico of the Ministry of Health. All patients who underwent ERCP between January 1, 2017, to May 30, 2022 were included. RESULTS: 485 ERCP were performed in the study period. Incidence of 1.6% post-ERCP duodenal perforation. The average age of the subjects 56.37 years. In-hospital stay of post-ERCP perforations averaged 9.37 days. The time of the endoscopic study at the time of the surgical procedure is 10 h on average. CONCLUSIONS: Post-ERCP duodenal perforation is a complication that occurs with a low incidence, it tends to increase the number of days of in-hospital stay and increases morbimortality of patients; therefore, it is important to be always alert.

ANTECEDENTES: La colangiopancreatografía retrógrada endoscópica (CPRE) es un estudio endoscópico en el cual se observa lateralmente el duodeno y se instrumenta la vía biliar. Existen diversas indicaciones y complicaciones en el procedimiento.

Smooth muscle contraction of the fundus of stomach, duodenum and bladder from mice exposed to a stress-based model of depression.

Several reports have demonstrated that depressive disorder is related to somatic symptoms including gastrointestinal or genitourinary alterations. The pathophysiological mechanisms underlying the gastrointestinal or genitourinary alterations associated with the depression are still not fully understood. Therefore, this study aimed to evaluate the motor activity of gastrointestinal (fundus of stomach and duodenum) and genitourinary tract (bladder) in a stress-based animal model of depression. Adult male mice were submitted to uncontrollable and unpredictable stress (learned helplessness model), controllable stress and non-stressful situations (control). Then, animals were euthanized and the fundus of stomach, duodenum segments or whole bladder were isolated and mounted in a standard organ bath preparation. We evaluated the contractile effects induced by KCl 80 mM for 5 min or carbachol (acetylcholine receptor agonist). The relaxant effects of isoproterenol (ß-adrenoceptor agonist) were also checked. Animals submitted to the learned helplessness model developed a helpless (depressive-like behavior) or resilient (does not exhibit depressive-like behavior) phenotype. The contractions induced by carbachol were diminished in fundus of stomach isolated from helpless and resilient animals. The isoproterenol-induced fundus of stomach relaxation was reduced in resilient but not helpless mice. The contractions/relaxation of duodenum segments isolated from helpless or resilient animals were not altered. Both helpless and resilient animals showed an increase in the bladder contractions induced by carbachol while the relaxant effects of isoproterenol were reduced when compared to control. Conversely, mice underwent a controllable stress situation did not exhibit alterations in the fundus of stomach or duodenum contraction/relaxation induced by pharmacological agents although a decrease in the bladder contraction induced by carbachol was found. In conclusion, incontrollable and unpredictable stress and not depressive phenotype (helpless animals) or controllable stress could be related to the alterations in motor activity of the fundus of stomach and bladder.

Gastric and Duodenal Fistulas in Crohn's Disease, a Surgical Challenge: Report of 5 Cases and a Review of the Literature.

BACKGROUND Fistulas involving the stomach and duodenum in Crohn's disease are rare (occurring in less than 1% of patients). Here, we reviewed registers from 855 patients with Crohn's disease treated in our service from January 2007 to December 2020 and found 4 cases of duodenal fistula and 1 case of gastric fistula. CASE REPORT The fistula origin was in the ileocolic segment in all cases, and all of the patients underwent preoperative optimization with improvement of nutritional status and infection control. They then underwent surgical treatment with resection of the affected segment and duodenal or gastric closure with covering by an omental patch. One case of a duodenal fistula was complicated by duodenal dehiscence. This was treated surgically with duodenojejunostomy. Each of the other patients had an uneventful postoperative course. All patients were successfully cured of their gastroduodenal fistulas, and at the time of this publication, none of them died or had fistula recurrence. CONCLUSIONS Fistulas with the involvement of the stomach and duodenum in patients with Crohn's disease are almost always due to inflammation in the ileum, colon, or previous ileocolic anastomosis. Management of this situation is complex and often requires clinical and surgical assistance; preoperative optimization of the patient's general condition can improve the surgical results. The surgical approach is based on resection of the affected segment and gastric or duodenal closure with covering by an omental patch. Gastrojejunostomy or duodenojejunostomy can be performed in selected patients with larger defects and minor jejunal disease. To prevent recurrence, prophylactic therapy with anti-TNF agents and early endoscopic surveillance are also essential for successful treatment.

Quiste de duplicación duodenal en un paciente pediátrico. Reporte de caso / Duodenal duplication cyst in a pediatric patient. Case report

Introducción. Los quistes de duplicación duodenal son malformaciones raras, que ocurren durante el desarrollo embriológico del tracto gastrointestinal. Caso clínico. Se presenta el caso de un niño de tres años, con cuadro clínico de dolor abdominal, náuseas y vómitos. La ecografía y la tomografía computarizada informaron una imagen quística entre el hígado, riñón derecho y colon. Resultados. Se realizó laparoscopia encontrando un quiste de duplicación duodenal con moco en la primera porción del duodeno. Se practicó una resección del quiste y mucosectomía del segmento restante. Conclusión. Los síntomas de un quiste de duplicación duodenal son inespecíficos y su hallazgo frecuentemente es incidental. El tratamiento quirúrgico depende del tamaño, la ubicación y su relación con la vía biliar.

Introduction. Duodenal duplication cysts are rare malformations that occur during the embryological development of the gastrointestinal tract. Clinical case. The case of a three-year-old boy with abdominal pain, nausea, and vomiting is presented. Ultrasound and computed tomography revealed a cyst between the liver, right kidney, and colon. Results. Laparoscopy was performed, finding a duodenal duplication cyst with mucus in the first portion of the duodenum. A resection of the cyst and mucosectomy of the remaining segment were performed. Conclusion. The symptoms of a duodenal duplication cyst are nonspecific and its finding is frequently incidental. Surgical treatment depends on the size, location, and relationship to the bile duct.

Rosuvastatin enhances alterations caused by Toxoplasma gondii in the duodenum of mice.

Infection by Toxoplasma gondii may compromise the intestinal histoarchitecture through the tissue reaction triggered by the parasite. Thus, this study evaluated whether treatment with rosuvastatin modifies duodenal changes caused by the chronic infection induced by cysts of T. gondii. For this, female Swiss mice were distributed into infected and treated group (ITG), infected group (IG), group treated with 40 mg/kg rosuvastatin (TG) and control group (CG). After 72 days of infection, the animals were euthanized, the duodenum was collected and processed for histopathological analysis. We observed an increase in immune cell infiltration in the IG, TG and ITG groups, with injury to the Brunner glands. The infection led to a reduction in collagen fibers and mast cells. Infected and treated animals showed an increase in collagen fibers, acidic mucin-producing goblet cells, intraepithelial lymphocytes and mast cells, in addition to the reduction of muscle, neutral mucin-producing and Paneth cells. While treatment with rosuvastatin alone led to increased muscle layer, proportion of neutral mucin-producing goblet cells, Paneth cells, and reduction of collagen fibers. These findings indicate that the infection and treatment caused changes in the homeostasis of the intestinal wall and treatment with rosuvastatin potentiated most parameters indicative of inflammation.

NECROTIZING PANCREATITIS WITH A RECURRING PANCREATIC PSEUDOCYST TREATED BY ENDOSCOPIC DUODENUM-GASTROPANCREATIC ANASTOMOSIS.

•ANP might evolve to MPD rupture which favors PP recurrence. •In cases of MPD rupture the pancreatic tail must be drained to the stomach. •Endoscopic duodenum-gastropancreatic anastomosis is a treatment option.

Paraganglioma gangliocítico metastásico: una rara entidad histológica diagnosticada tras una duodenopancreatectomía / Metastatic gangliocytic paraganglioma: a rare histological entity diagnosed after duodenopancreatectomy

Introducción. El paraganglioma gangliocítico es una entidad histológica infrecuente, siendo el duodeno su principal localización extra ganglionar. Caso clínico. Se trata de un varón de 54 años que consulta por dolor abdominal y hemorragia digestiva alta. Se diagnosticó una lesión sospechosa de ampuloma por lo que se realizó una duodenopancreatectomía cefálica. En el análisis histológico, se confirmó el diagnóstico de paraganglioma gangliocítico metastásico por la presencia patognomónica de tres estirpes celulares (epiteliales, ganglionares y Schwann-like). Dado su buen pronóstico, asociado con baja quimiosensibilidad, no recibió tratamiento adyuvante. Resultados. Durante el seguimiento, el paciente no presentó complicaciones tardías, ni signos de recidiva después de un año de la intervención. Conclusión. El paraganglioma gangliocítico es una entidad potencialmente maligna, que requiere un correcto estudio de extensión y un seguimiento estrecho a largo plazo

Introduction. Gangliocytic paraganglioma is a rare histological entity, with the duodenum being its main extra-nodal location. Clinical case. This is a 54-year-old man who presented with abdominal pain and upper gastrointestinal bleeding. A suspicious ampuloma lesion was diagnosed, for which a pancreaticoduodenectomy was performed. In the histological analysis, the diagnosis of metastatic gangliocytic paraganglioma was confirmed by the pathognomonic presence of three cell lines (epithelial, ganglionic, and Schwann-like). Given his good prognosis associated with low chemosensitivity, he did not receive adjuvant treatment. Results. During follow-up, the patient did not present late complications or signs of recurrence one year after the intervention. Conclusion. Gangliocytic paraganglioma is a potentially malignant entity that requires a correct extension study and close long-term follow-up

Causa rara de dolor abdominal recurrente; coexistencia del síndrome de Wilkie y el síndrome del cascanueces / A rare cause of recurrent abdominal pain; the coexistence of Wilkie's syndrome and nutcracker syndrome

El síndrome del cascanueces es un síndrome que presenta síntomas clínicos como hematuria, proteinuria ortostática, congestión pélvica, varicocele del lado izquierdo, hipertensión y dolor en fosa renal. Estos síntomas se producen por la compresión de la vena renal izquierda entre la aorta y la arteria mesentérica superior. En el síndrome de Wilkie, la tercera porción del duodeno está comprimida entre la arteria mesentérica superior y la aorta abdominal, lo que provoca diversos síntomas gastrointestinales. La coexistencia de estos dos síndromes constituye una afección rara y se incluye como casos clínicos en la bibliografía. En este artículo, se presentan los resultados clínicos y radiológicos de un paciente de 17 años que presentaba dolor abdominal recurrente debido al síndrome de Wilkie, acompañado del síndrome del cascanueces que le provocaba proteinuria, por lo que el paciente fue derivado a los consultorios externos de reumatología pediátrica con un diagnóstico preliminar de fiebre mediterránea familiar.

Nutcracker syndrome is a syndrome that has clinical symptoms such as hematuria, orthostatic proteinuria, pelvic congestion, left-sided varicocele, hypertension, and flank pain. These symptoms occur because of the compression of the left renal vein between the aorta and the superior mesenteric artery. In Wilkie's syndrome, the third part of the duodenum is compressed between the superior mesenteric artery and the abdominal aorta, causing various gastrointestinal symptoms. The coexistence of these two syndromes is a rare condition and is included as case reports in the literature. This article presents the clinical and radiological results of a 17-year-old male patient who had recurrent abdominal pain due to Wilkie's syndrome, which was accompanied by nutcracker syndrome that caused proteinuria, and for this reason, the patient was referred to the Pediatric Rheumatology outpatient clinic with a preliminary diagnosis of familial Mediterranean fever.

The Effectiveness and Safety of the Duodenal-Jejunal Bypass Liner (DJBL) for the Management of Obesity and Glycaemic Control: a Systematic Review and Meta-Analysis of Randomized Controlled Trials.

INTRODUCTION: The duodenal-jejunal bypass liner (DJBL) is a less-invasive treatment of obesity and type 2 diabetes mellitus (T2DM). METHODS: This is a systematic review and meta-analysis including randomized clinical trials (RCTs) comparing DJBL versus sham or pharmacotherapies aiming to evaluate the effectiveness and safety of DJBL. RESULTS: Ten RCTs (681 patients) were included. The DJBL group showed superior excess weight loss (+ 11.4% [+ 7.75 to + 15.03%], p < 0.00001) and higher decrease in HbA1c compared to the control group (- 2.73 ± 0.5 vs. - 1.73 ± 0.4, p = 0.0001). Severe adverse events (SAEs) occurred in 19.7%. CONCLUSION: The DJBL did not reach the ASGE/ASMBS thresholds for the treatment of obesity. However, it is important to state that many SAEs were not really severe. Therefore, we believe this therapy plays an important role in the management obesity and T2DM.

A rare cause of recurrent abdominal pain; the coexistence of Wilkie's syndrome and nutcracker syndrome. / Causa rara de dolor abdominal recurrente; coexistencia del síndrome de Wilkie y el síndrome del cascanueces.

Nutcracker syndrome is a syndrome that has clinical symptoms such as hematuria, orthostatic proteinuria, pelvic congestion, left-sided varicocele, hypertension, and flank pain. These symptoms occur because of the compression of the left renal vein between the aorta and the superior mesenteric artery. In Wilkie's syndrome, the third part of the duodenum is compressed between the superior mesenteric artery and the abdominal aorta, causing various gastrointestinal symptoms. The coexistence of these two syndromes is a rare condition and is included as case reports in the literature. This article presents the clinical and radiological results of a 17-year-old male patient who had recurrent abdominal pain due to Wilkie's syndrome, which was accompanied by nutcracker syndrome that caused proteinuria, and for this reason, the patient was referred to the Pediatric Rheumatology outpatient clinic with a preliminary diagnosis of familial Mediterranean fever.
