Objective: Rare disease. Background: Superior mesenteric artery syndrome, also known as Wilkie's syndrome, is a rare etiology of obstruction of the lower duodenum between the superior mesenteric artery and aorta. It often presents with unspecific abdominal pain and laboratory findings, resulting in difficult diagnosis and treatment. Case Report: A 21-year-old male patient was admitted to our clinic with a 13-month history of coughing, ill feeling, night sweats, vomiting, unintentional weight loss, and epigastric pain. Despite recurrent referral, the diagnostic panels, including a full abdominal laboratory workup, were unremarkable, with the following results: pancreatic amylase: 34.6 U/L, pancreatic lipase: 22 U/L, bilirubin: 0.66 mg/dL, aspartate aminotransferase: 21 U/L, alanine aminotransferase: 40 U/L, white blood cells: 12.59×109/L, plasma total protein: 8.4 g/dL, and hemoglobin: 14.7 g/dL. An abdominal computed tomography scan revealed a paucity of the mesenteric artery and subcutaneous fat, the dilation of the stomach and compression of the duodenum between the superior mesenteric artery and aorta, and an aorto-mesenteric distance of 5.1 mm, resembling superior mesenteric artery syndrome (Wilkie's syndrome). Conservative therapy, including high caloric nutritional support, was administered. A gastroscopy was performed to dilate the distal portion of the duodenum, to enable a physiological passage. The patient was discharged 5 days after diagnosis in good condition, with weight gain, and continued to receive regular follow-up with our outpatient department. Conclusions: This case underlines the importance of considering rare etiologies of abdominal symptoms for concise diagnosis, along with the importance of considering nonsurgical treatment, especially in young patients.

Background: Cognitive errors are common in medical practice and can have serious consequences for patients related to misdiagnosis and delays in diagnosis and treatment. We report a case in which cognitive error substantially influenced a patient's diagnosis and treatment. Case Report: This report recounts the case of an adolescent girl with symptoms similar to those of her previous episodes of tetrahydrocannabinol-induced hyperemesis, despite a 21-kg weight loss over 6 months. She sought care at multiple facilities until finally being diagnosed with superior mesenteric artery syndrome. Treatment was conservative with intravenous hydration, nasogastric feeding, and gastric decompression until duodenal compression was relieved. The patient's condition had improved at 7-month follow-up, and she declined surgical consultation. Conclusions: This case report seeks to raise awareness of the effects of cognitive errors in clinical practice. This tendency to prematurely attribute symptoms to a known diagnosis and thereby overlook alternative and potentially more accurate explanations can lead to delays in diagnoses and treatments. Awareness of cognitive error is especially important in the context of the increasing prevalence of legalization of tetrahydrocannabinol/marijuana in several states. Superior mesenteric artery syndrome, although rare, is linked to high morbidity and mortality when the diagnosis is delayed; thus, it is crucial to consider it in the differential diagnosis for a patient with weight loss and abdominal pain. By sharing this case, we hope clinicians and patients can become more aware of this rare consequence of tetrahydrocannabinol use to facilitate more comprehensive patient-centered investigations.

Intestinal obstruction is a common surgical emergency with high morbidity and mortality. Patients presenting with features of small bowel obstruction need urgent evaluation to avoid complications such as bowel gangrene, perforation, or peritonitis. Imaging is necessary in most cases of suspected bowel obstruction, to take an appropriate decision, for apt patient management. Among the common causes of small bowel obstruction, adhesions, external herniae, malignancies, and Crohn's disease top the chart. Imaging helps in determining the presence of obstruction, the severity of obstruction, transition point, cause of obstruction, and associated complications such as strangulation, bowel gangrene, and peritonitis. This review is based on the cases with unusual causes of bowel obstruction encountered during our routine practice and also on the extensive literature search through the standard textbooks and electronic databases. Through this review we want our readers to have sound knowledge of the imaging characteristics of the uncommon yet important causes of bowel obstruction. We have also revisited and structured a checklist to simplify the approach while reporting a suspected case of small bowel obstruction. Imaging plays a key role in the diagnosis of small bowel obstruction and in determining the cause and associated complications. Apart from the common causes of small bowel obstruction, we should also be aware of the uncommon causes of small bowel obstruction and their imaging characteristics to make an accurate diagnosis and for apt patient management.

Superior mesenteric artery syndrome, or Wilkie's syndrome, is one of the rarest gastrointestinal disorders known to medical science. It is characterized by the vascular clamp of the third portion of the duodenum, between the superior mesenteric artery and the aorta. It presents as an uncommon cause of upper intestinal obstruction. Imaging is required, preferably with a contrast-enhanced CT or an MRI; conservative management is preferred, leaving surgery for the most complex cases.We present the case of a 34-year-old man with Duchenne's muscular dystrophy and a history of substantial weight loss after hospital admission for aspiration pneumonia. He underwent an abdominal CT scan that showed enlargement of the stomach, the second and third parts of the duodenum; without observing masses, the patient received conservative management with a nasojejunal feeding tube. At the outpatient reevaluation, 1 month postdischarge, he became asymptomatic and had progressive weight gain.

Background: This case report describes a novel endovascular technique for treating superior mesenteric artery (SMA) occlusion, a condition leading to chronic mesenteric ischemia (CMI). Traditional treatment methods for CMI, primarily due to SMA stenosis, are often complex and risky, particularly for patients unsuitable for conventional surgery. Objective: This study details the application of retrograde recanalization followed by the deployment of a VIABAHN covered stent in a patient with complete SMA ostium occlusion. Methods: The procedure's success in re-establishing mesenteric blood flow demonstrates its potential as a less invasive, safer alternative to traditional surgical approaches. This technique's innovation lies in its retrograde approach, allowing for effective treatment in cases where antegrade access is unfeasible. Results: The patient showed significant symptom improvement without procedural complications, underscoring the method's efficacy and safety. Conclusion : These findings suggest that retrograde stent implantation can be a viable option for managing SMA occlusions, especially in high-risk surgical cases. The successful application of this technique in this case contributes to the evolving landscape of endovascular interventions in vascular surgery and offers a promising direction for future research and clinical practice in treating SMA-related conditions.

Abstract Superior mesenteric artery syndrome (SMAS) is a rare and unpredictable complication after correction spine surgery for adolescent idiopathic scoliosis (AIS). The management of this condition is poorly investigated, with controversial outcomes. This investigation systematically reviewed current evidence on pathogenesis, risk factors, management, and outcomes of SMAS following correction spine surgery for AIS. The present systematic review was conducted according to the 2020 PRISMA statement. All the included investigations reported SMAS presentation following scoliosis correction surgery in AIS. 29 articles with 61 eligible patients were included in this review. The mean age of the patients was 15.8 ± 7.2 years. The mean weight was 45.3 ± 8.0 kg, the mean height 159.6 ± 13.6 cm, and the mean BMI 16.5 ± 2.9 kg/m2. The mean duration of the treatment for SMAS was 21.6 ± 10.3 days. The mean interval between spine surgery and symptoms of SAMS was 69 days, with high between-studies variability (3 days to 4 years). Prompt identification of risk factors and an early diagnosis are necessary to manage SMAS and reduce the risk of complications. Additional investigations are required to establish risk factors and diagnostic criteria. Level of evidence Level IV, systematic review.

Left renal vein variants are not commonly observed in the general population. Usually, the renal vein runs in front of the aorta before entering the inferior vena cava, while the most common variants include the presence of a circumaortic or retroaortic renal vein. However, when present, left venal rein variants are important to recognize due to their potential clinical and surgical relevance. In this regard, CE-CT is an instrument with high sensitivity and specificity in detecting vascular anomalies and can certainly help diagnose. In this article, we present a unique case of a left venal rein compressed between the left iliac artery and vertebral bodies associated with the presence of a superior mesenteric artery Syndrome, another rare entity that occurs when the duodenum is compressed between the aorta and the superior mesenteric artery.

Superior mesenteric artery (SMA) syndrome or Wilkie's syndrome is a vascular compression disorder that causes the abnormal compression of the third portion of the duodenum by the SMA. It has a low incidence rate, which is higher in young women, and is rarely associated with the Nutcracker phenomenon: a condition of the compression of the left renal vein between the SMA and the aorta, which manifests as pain in the left flank and pelvis. Here, we report on the case of a 54-year-old woman with a history of repeated episodes of abdominal pain caused by the Nutcracker syndrome and Wilkie's syndrome. [ABSTRACT FROM AUTHOR]

Background: Superior mesenteric artery syndrome is a rare condition that has only around 400 reported cases so far. Typically, the superior mesenteric artery branches off the abdominal aorta at 45° to create an aortomesenteric distance of 10–28 mm, with the duodenum passing through. However, if this aortomesenteric angle reduces to less than 25°, the third portion of the duodenum becomes compressed between the SMA and aorta, causing mechanical obstruction. Case presentation: This case report aims to demonstrate the diagnostic difficulties and the laparoscopic management of a 52-year-old Indian male presenting with abdominal pain and vomiting, with associated weight loss. Imaging was further suggestive of high intestinal obstruction, and he was later found to have superior mesenteric artery syndrome. Conclusion: Taking into account a significant reduction in morbidity, we propose laparoscopic duodenojejunostomy to be the new procedure of choice for superior mesenteric artery syndrome.

Superior mesenteric artery (SMA) syndrome is a rare cause of proximal bowel obstruction due to duodenal compression by the SMA. The morbidity and mortality associated with delayed diagnosis and its complications make it an important differential cause for bowel obstruction. We report a case of mega-stomach secondary to SMA syndrome requiring total gastrectomy. An 18-year-old male presented with vomiting, abdominal pain and shock after a buffet. Computed tomography (CT) imaging revealed a grossly distended stomach (113 × 187 × 350mm) and a transition point at the third part of the duodenum, along with pneumatosis and portal venous gas. Emergency gastroscopy showed blood and necrotic mucosa. Laparotomy confirmed full thickness necrosis and the patient underwent a total gastrectomy with Roux-en-Y reconstruction. Postoperatively, he had a brief intensive care stay and recovered without complications. This case underscores the importance of considering SMA syndrome during presentations of acute gastric dilatation. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

Background Superior mesenteric artery syndrome (SMAS) is a rare condition, for which laparoscopic surgery was successfully performed safely and with long-term efficacy.Methods This single center retrospective clinical study comprised 66 patients with SMAS, surgically treated between January 2010 and January 2020, who were allocated to three different surgical groups according to their medical history and symptoms (Laparoscopic duodenojejunostomy, n = 35; Gastrojejunostomy, n = 16; Duodenojejunostomy plus gastrojejunostomy, n = 15). Patient demographics, surgical data and postoperative outcomes were retrieved from the medical records.Results All operations were successfully completed laparoscopically, and with a median follow-up of 65 months, the overall symptom score was significantly reduced from 32 to 8 (p

Abstract Background Superior mesenteric artery (SMA) syndrome, also known as Wilkie’s syndrome, is a rare but serious complication following scoliosis correction surgery. It occurs as a result of mechanical compression of third part of duodenum between the SMA and aorta. This condition occurs most commonly in significantly underweight patients with deformities, and usually during the first week following spinal deformity corrective surgeries. The angle between the abdominal aorta and the SMA gets reduced following spinal lengthening during deformity correction surgery causing compression of third part of duodenum resulting in development of SMA syndrome. Case presentation. We present a case of 17-year-old male with congenital scoliosis with a 70-degree scoliotic curve who underwent spinal deformity correction surgery with posterior instrumented fusion. Post-operative course was uneventful and the patient was discharged after suture removal on post-operative day 15. The patient presented after 21-days of symptom onset on post-operative-day 51, with a 3 week history of post-prandial vomiting, abdominal pain and distension which resulted in rapid weight loss of 11 kg. A CT-angiogram showed obstruction at third part of duodenum. After reviewing clinical and radiological profile of the patient, a diagnosis of SMA syndrome was made. Conservative management was tried, but due to rapid deterioration of patient condition and symptoms of complete intestinal obstruction, the patient was treated surgically by gastro-jejunostomy and side-to-side jejuno-jejunostomy, which improved his condition. Conclusion SMA syndrome can occur much later than previously reported cases and with potentially life-threatening symptoms following scoliosis correction. Having a high index of suspicion, early recognition of condition and institution of appropriate treatment are essential to prevent occurrence of severe complications including risk of intestinal perforation and mortality. This case highlights management of delayed onset of SMA syndrome, with presentation further delayed after symptom onset, as is common in developing parts of the world, due to limited availability and accessibility of resources, and low socio-economic status of large segments of the population.

In pregnancy, advanced vertebral hemangiomas may be seen, and these require treatment. The case reported here is of a 35‐year‐old female in the 32nd week of pregnancy who was admitted to the orthopaedics clinic with a history of backache and difficulty walking. A burst fracture of L1 associated with a vertebral hemangioma was identified with an L3 compression fracture secondary to osteoporosis. The local kyphosis angle between T12 and L2 was 27°. Kyphotic deformity was corrected and postoperatively, the measured T12–L2 local kyphotic angle was 9°. Twelve hours postoperatively, oral nutrition was allowed, but she developed nausea and vomiting and twenty‐four hours postoperatively, an electrolyte imbalance developed. Postoperatively, the patient was diagnosed with superior mesenteric artery syndrome. To the best of our knowledge, this is the first reported case of superior mesenteric artery syndrome, which occurred following the correction of a kyphotic deformity that had developed secondary to an advanced hemangioma in pregnancy.

Vascular compression syndromes are a diverse group of pathologies that can manifest asymptomatically and incidentally in otherwise healthy individuals or symptomatically with a spectrum of presentations. Due to their relative rarity, these syndromes are often poorly understood and overlooked. Early identification of these syndromes can have a significant impact on subsequent clinical management. This pictorial review provides a concise summary of seven vascular compression syndromes within the abdomen and pelvis including median arcuate ligament (MAL) syndrome, superior mesenteric artery (SMA) syndrome, nutcracker syndrome (NCS), May-Thurner syndrome (MTS), ureteropelvic junction obstruction (UPJO), vascular compression of the ureter, and portal biliopathy. The demographics, pathophysiology, predisposing factors, and expected treatment for each compression syndrome are reviewed. Salient imaging features of each entity are illustrated through imaging examples using multiple modalities including ultrasound, fluoroscopy, CT, and MRI. [ABSTRACT FROM AUTHOR]

Background: Superior mesenteric artery (SMA) syndrome is a rare cause of small bowel obstruction due to extrinsic compression of the duodenum. This study aimed to evaluate the presentation, surgical management, and outcomes of seven patients with SMA syndrome treated at two tertiary care centers in India between June 2015 and January 2023.All patients presented with chronic vomiting, nausea, epigastric pain, and weight loss. Diagnosis was confirmed by radiological findings, including CT scans demonstrating a narrowed aortomesenteric angle (<22 degrees) and dilated proximal duodenum. Surgical intervention was the mainstay of treatment due to minimal success with non-operative management. All patients except one underwent laparoscopic duodenojejunostomy. One patient with a post-operative stricture required conversion to a Roux-en-Y duodenojejunostomy. Methods: We have managed seven cases of duodenal obstruction due to SMA syndrome during the time period of June 2015 to January 2023. The study included cases pooled from two tertiary care centers of Andhra Pradesh. The primary evaluation was done by gastroenterologists, psychologists and followed by detailed surgical evaluation. Ultrasonography and upper endoscopy were done for all cases followed by CT scan of the abdomen in all the cases. All the patients had clinical and radiological findings consistent with SMA syndrome. Data collected included patient demographics, clinical presentation, operative data, and outcomes. Data are presented as mean ± standard deviation for continuous variables and as percentages for categorical variables. Results: The seven patients included 5females and 2 males (female to male ratio was 2.5:1). The mean age of the cases was 21.29 ± 4.15 years (range 13 - 26 years). The Comorbidities identified in these cases included Psychiatric/anxiety (14.29%), anorexia (28.57%), Pancreatitis (14.29%), Mild scoliosis (14.29%), Binge/fasting (14.29%). No clear reason was identified in one case (14.29%) and attributed to fibromyalgia. One patient had previous laparoscopic appendicectomy, but no other patient had any history of abdominal or spinal surgery. [ABSTRACT FROM AUTHOR]

Wilkie's syndrome is an unusual cause of upper intestinal obstruction due to mechanical compression of the superior mesenteric artery (SMA) to the duodenum, with nonspecific symptoms, whose diagnosis is confirmed by angiotomography. Initially, the treatment is conservative to regain weight and restore mesenteric adipose tissue, associated with postural changes of the patient. If this fails, surgical treatment is indicated, being laparoscopic duodenojejunostomy described as the gold standard. Robotics' assistance is feasible and safe to carry out the procedure. We present the case of a 21-year-old male patient who comes with stabbing abdominal pain and persistent postprandial vomiting that has caused weight loss of 11 kilograms in the last 2 years without apparent cause, associated with gastroesophageal reflux. During the procedure, we evidenced open diaphragmatic pillars and duodenal compression due to SMA, and robotic-assisted laparoscopic hyatoplasty + Nissen fundoplication + duodenojejunostomy were performed without complications, with excellent post-surgical results.

Superior mesenteric artery (SMA) syndrome, also known as Wilkie's syndrome, is a rare disease presenting as an acute abdomen. It has a clinical presentation similar to intestinal obstruction and is often missed during diagnosis. Reduced weight leading to loss of fat pad between SMA and aorta is the main pathophysiology. Diagnosis is made through barium meal and CT scan. Conservative management remains the treatment of choice; however, surgery is opted for in refractory cases. Key Clinical Message: Superior mesenteric artery (SMA) syndrome, also known as Wilkie's syndrome, is a rare disease presenting as an acute abdomen with clinical features similar to intestinal obstruction. This is a case of SMA syndrome in an adult male with a decrease in aortomesenteric angle, with no predisposing condition. [ABSTRACT FROM AUTHOR]

Background: There are no reports of anesthesia use in adult patients with Silver-Russell syndrome (SRS). Here, we report our experience with anesthesia in an adult patient with SRS complicated by chronic respiratory failure. Case presentation: A 33-year-old woman was clinically diagnosed with SRS. She had severe chronic respiratory failure, complicated by superior mesenteric artery syndrome. Percutaneous gastrostomy was scheduled for nutritional management under epidural anesthesia; however, soon after esophagogastroduodenoscopy was started, she lost consciousness and spontaneous respiration. The patient was urgently intubated and converted to general anesthesia. The end-tidal carbon dioxide tension was > 90 mmHg at intubation. Conclusions: Adult SRS patients with chronic respiratory failure have a risk of CO2 narcosis. SRS also requires preparation for difficult airway management during the perioperative period.

This article discusses two case reports of patients diagnosed with superior mesenteric artery syndrome, also known as Wilkie's syndrome. The syndrome is characterized by the compression of the third part of the duodenum between the aorta and the superior mesenteric artery. The patients presented with symptoms such as nausea, vomiting, and weight loss. While one patient recovered with conservative treatment, the other required two surgeries. The article emphasizes the importance of considering SMA syndrome in patients with unexplained symptoms and highlights the need for timely surgical intervention when conservative treatment is ineffective.

Isolated superior mesenteric artery dissection (ISMAD) is a rare cause of acute abdominal conditions. Most cases of ISMAD have a favorable prognosis, and only a few cases of ISMAD-associated intestinal necrosis have been reported. A 75-year-old male was referred to our department because of abdominal pain and portal venous gas detected on imaging. Computed tomography suggested ileal necrosis, necessitating emergency surgery. Indocyanine green was used for blood flow assessment; however, no fluorescence was observed in the ileum proximal to the Bauhin valve, leading to the decision for ileocecal resection. On postoperative day 6, abdominal pain recurred when meals were resumed. As a surgical intervention for ISMAD, a bypass was created using the left great saphenous vein as a graft between the superior mesenteric artery and the right external iliac artery. This case highlights a rare occurrence where intestinal necrosis recurred due to ISMAD. We propose that in cases of ISMAD with concomitant intestinal necrosis, a more aggressive revascularization strategy for the dissected segment of the superior mesenteric artery may be required.

Background. Superior mesenteric artery syndrome (SMAS) is a rare condition caused by the compression of the duodenum, which may occur in the case of fast weight loss. Currently, the relationship between superior mesenteric artery syndrome and anorexia nervosa is still unclear. The aim of this study is to identify the precocious clinical signs and symptoms of SMAS in patients affected by anorexia nervosa so as not to delay the diagnosis. Methods. We present the clinical case of a young female patient with anorexia nervosa complicated by SMAS. We performed a literature review of SMAS in children affected by anorexia nervosa between 1962 and 2023, according to the PRISMA Extension Guide for Scoping Reviews. Results. Reviewing the literature, 11 clinical cases were described for the pediatric age. The median age at diagnosis was 17 years (ranging from 13 to 18 years). The diagnosis of SMAS may be challenging as symptoms overlap those of anorexia, but it should be kept in mind mostly in cases of post-prandial abdominal pain, anxiety or depression, nausea, vomiting, and weight loss. Conclusion. Even specific clinical symptoms may act as flag tags to drive attention to this rare but potentially fatal condition. [ABSTRACT FROM AUTHOR]

Superior mesenteric artery syndrome (SMAS) is a rare and unusual disease, suspected clinically and confirmed radiologically. It represents a duodenal obstruction secondary to the impingement of the third portion of the duodenum between the abdominal aorta (AA) and the superior mesenteric artery (SMA) due to decreased intraabdominal fat. High morbidity and mortality rates are linked to missed or late diagnosis that can lead to complications, such as gastric perforation and gastric hemorrhage. We present the case of a 33-year-old man who was not previously known to have a SMAS, who presented to the emergency department with signs of septic shock, complaining of fever and respiratory symptoms for several days. Investigations showed aspiration pneumonia secondary to an upper gastrointestinal obstruction with signs of SMAS on a computed tomography (CT) scanner. Acute and rapid deterioration led to cardiac arrest and death. Through this article, we highlight the importance of early and correct diagnosis of SMAS which can sometimes be challenging, since no number is strictly diagnostic and radiological images must be interpreted in light of the clinical history and physical examination.

Background: Celiacomesenteric trunk (CMT) is one of the rare congenital anomalies of the splanchnic vasculature, characterized by the common trunk origin of the superior mesenteric artery (SMA) and celiac trunk from the abdominal aorta. Dissection of CMT with isolated SMA involvement without bowel ischemia has been rarely reported in the literature. Case presentation: A 48-year-old male presented with generalized abdominal pain for 20 days, which increased after food intake. He also gave a history of passing loose stools on and off in the last 10–15 days, associated with melena for 4–5 days. Computed tomography (CT) and CT angiography (CTA) study of the abdomen demonstrated the common trunk origin of SMA and celiac trunk from the abdominal aorta at the D12–L1 disk level, consistent with the celiacomesenteric trunk (CMT). CTA also revealed dissection of CMT with isolated extension in the SMA origin and thrombosis in the mid and distal SMA. No bowel or mesenteric ischemia was seen due to extensive collateral supply to distal-most SMA and its branches, mainly through the inferior mesenteric artery (IMA) via an arc of Riolan and artery of Drummond. The patient was managed conservatively with bowel rest, anti-thrombolytics, and anticoagulant therapy based on imaging findings of short-segment dissection with no signs of bowel or mesenteric ischemia. Conclusion: Diagnosis of rare vascular anomalies like CMT with associated complications of dissection and thrombosis is critical in patients with abdominal pain for prompt and precise management. CTA of the abdomen is essential for accurate diagnosis and characterization of the abnormality, which helps decide between conservative and surgical treatments. [ABSTRACT FROM AUTHOR]

Introduction: Secondary sclerosing cholangitis in critically ill patients (SSC-CIP) is a rare but underdiagnosed entity that occurs after life-threatening events and treatment in the intensive care unit (ICU). The etiology of SSC-CIP is not fully understood but may be caused by ischemic bile duct injury. SSC-CIP is a cholestatic liver disease that rapidly progresses to liver cirrhosis, with a high mortality rate in the first year of 50%. Endoscopic retrograde cholangiopancreatography (ERCP), which is the gold standard for diagnosing SSC-CIP, shows primary SC-like changes, usually in the intrahepatic bile ducts. Biliary cast formation is pathognomonic for SSC-CIP. No proven effective conservative treatment is available for SSC-CIP, and liver transplantation is the only curative therapy when liver cirrhosis or recurrent cholangitis occurs. Case Presentation: We report the case of a 47-year-old male patient who developed cholestasis after a long treatment in the ICU for severe pneumonia. ERCP showed characteristic findings with rarefication and multiple segmental stenosis in the intrahepatic bile ducts. We removed multiple biliary casts from the bile ducts. Conclusion: SSC-CIP should be considered for ICU patients with unclear cholestasis, especially when the cholestasis persists after recovery from the underlying disease. Early diagnosis is important to achieve better outcomes; without liver transplantation, the prognosis is generally poor. [ABSTRACT FROM AUTHOR]

An acute vascular angle between the superior mesenteric artery and the Aorta may compress the third part of the duodenum (SMA Syndrome) and the Left Renal Vein (Renal Nutcracker Syndrome). Usually, patients are young females with a lean stature. Symptoms of outlet obstruction and pelvic congestion syndrome may be present. Our patient presented with bilious vomiting and unintentional weight loss for the last 6-8 months. On further inquiry, she had dysmenorrhea and left flank pain associated with microscopic haematuria. Duodenojejunostomy with Left Renal Vein (LRV) re-positioning was performed. She recovered uneventfully and has improved intake with mild or no pain troubling her at 6 weeks of surgery.

Introduction: Superior mesenteric artery syndrome (SMAS) is a complete or incomplete obstruction of the third portion of the duodenum caused by compression between the aorta and the superior mesenteric artery (SMA). Some diagnostic strategies and treatments exist for adults; however, in neonates, these are controversial because the condition is uncommon. Case presentation: A 4-day-old male infant with a birth weight of 2630 g was referred to our hospital with a 2-day history of bilious vomiting. Ultrasonography and contrast enema revealed no malrotation or midgut volvulus. On day 7 of life, an upper gastrointestinal series with contrast revealed obstruction of passage in the third portion of the duodenum. Congenital duodenal stenosis was suspected, and exploratory laparotomy was performed on day 9 of life. The SMA compressed and narrowed the third portion of the duodenum. The duodenum was mobilized and the ligament of Treitz was divided using the technique described by Strong, which released the duodenal compression. A feeding tube was successfully inserted through the duodenum. No duodenal web was observed and SMAS was suspected. The patient's postoperative course was uneventful and SMAS was diagnosed. Complete oral intake was achieved on postoperative day 20, and the patient was discharged on postoperative day 30. Conclusions: Neonatal SMAS is a rare but possible cause of duodenal obstruction. The procedure reported by Strong is useful in neonatal cases.

Key Clinical Message Superior mesenteric artery (SMA) syndrome, also known as Wilkie's syndrome, is a rare disease presenting as an acute abdomen with clinical features similar to intestinal obstruction. This is a case of SMA syndrome in an adult male with a decrease in aortomesenteric angle, with no predisposing condition.

Abstract The superior mesenteric artery syndrome (SMAS), also known as Wilkie’s syndrome, is a duodenal obstruction caused by the compression of the third part of the duodenum between the superior mesenteric artery (SMA) and the aorta. This condition often arises due to the disappearance of perivascular fatty tissue, as well as advanced stages of malnutrition and weight loss. Patients typically experience symptoms such as vomiting, fullness, and postprandial epigastric pain. While initial management involves conservative measures, surgery becomes necessary if symptoms do not improve. Here, we present the case of a 25-year-old man diagnosed with SMAS. Despite undergoing conservative management for three months, the symptoms did not regress. Subsequently, a laparoscopic duodeno-jejunostomy was performed, resulting in an uneventful postoperative period, disappearance of vomiting and epigastric pain, and a weight gain of 14 kg after one year.

Abstract Purpose There are only a few case reports of laparoscopic lateral duodenojejunostomy (LLDJ) in children with Wilkie’s syndrome, also known as superior mesenteric artery compression syndrome (SMAS). We aimed to describe our laparoscopic technique and evaluate its outcomes for SMAS in children. Methods From January 2013 to May 2021, SMAS children who received LLDJ were included. The procedure was carried out utilizing the four-trocar technique. The elevation of the transverse colon allows good exposure of the dilated and bulging second and third sections of the duodenum. Using a linear stapler, we established a lateral anastomosis connecting the proximal jejunum with the third part of the duodenum. Following that, a running suture was used to intracorporeally close the common enterotomy. Clinical data on patients was collected for analysis. The demographics, diagnostic findings, and postoperative outcomes were analyzed retrospectively. Results We retrospectively analyzed 9 SMAS patients (6 females and 3 males) who underwent LLDJ, aged between 7 and 17 years old. The mean operative time was 118.4 ± 16.5 min and the mean estimated blood loss was 5.6 ± 1.4 ml. There were no conversion, intraoperative complications or immediate postoperative complications. The mean postoperative hospital stay was 6.8 ± 1.9 days and the mean follow-up time was 5.4 ± 3.0 years. During follow-up, seven patients (77.8%) experienced complete recovery of symptoms prior to surgery. One patient (11.1%) still had mild vomiting, which resolved with medication. Another patient (11.1%) developed psychological-induced nausea, which significantly improved after treatment with education, training and diet management. Conclusions LLDJ represents a feasible and safe treatment option for SMAS in well-selected children. Further evaluation with more cases and case-control studies is required for the real benefits.

Abstract Background Superior mesenteric artery (SMA) syndrome is an underdiagnosed complication in anorexia nervosa (AN) patients, which results from weight loss-induced atrophy of the mesenteric fat pad, causing compression of the third part of the duodenum. SMA syndrome can be life-threatening as its nonspecific symptomatology often results in a delayed diagnosis. It is a rare condition, but its true prevalence may be higher than the reported numbers. A history of persistent nausea and vomiting after oral intake and weight loss in AN should raise suspicion about this diagnosis, as weight loss is the most significant factor in this diagnosis. Other high-risk factors include rapid, extreme weight loss, anatomical abnormalities, or a history of prior abdominal or spinal surgeries. Case presentation The patient presented in this report was a 26-year-old Caucasian female with a history of severe enduring anorexia nervosa. This patient suffered from an insidious case of SMA syndrome secondary to AN. This patient presented with vague symptoms of nausea and vomiting, persistent abdominal pain, and rapid weight loss. The patient was successfully treated but could have had a much different outcome if the diagnosis had been further delayed. Conclusions An awareness of SMA syndrome and its clinical presentation within similar populations can prevent complications and even fatalities that come with it.

The rare pathological condition known as superior mesenteric artery (SMA) (Wilkie) syndrome arises when the third part of the duodenum experiences constriction due to compression between the aorta and the proximal segment of the SMA. The main complaints are nausea, vomiting, epigastric pain, and bloating with significant weight loss. Reported cases of this syndrome have been observed in patients who have scoliosis, suffered burns, led sedentary lifestyles, or experienced unexplained weight loss. In cases where there is unexplained rapid weight loss and recurrent obstructive findings that deviate from common causes, clinicians should include SMA syndrome in their differential diagnosis. This article presents a case of SMA syndrome, which has long affected the patient’s quality of life due to diagnostic difficulties, and discusses the disease’s diagnosis and management.

Abstract Background Superior mesenteric artery syndrome (SMAS), also known as Wilkie's syndrome, is a rare disease that mainly presents as intestinal obstruction with a variable incidence ranging from 0.013 to 0.3% (Salehzadeh et al. in Case Rep Gastrointest Med, 2019, 10.1155/2019/3458601). In this syndrome, the third part of the duodenum, located between the abdominal aorta and the superior mesenteric artery, is wholly or partially obstructed (Mosalli et al. in J Pediatr Surg 46:e29–31, 2011). Case presentation An 8-years-old Arabian male patient was admitted to the gastrointestinal department at the pediatric hospital in Damascus, Syria, with complaints of chronic abdominal pain and periodic vomiting since he was two years old. At the age of Seven, he was diagnosed with appendicitis, and after two months of persistent symptoms, he was diagnosed with an umbilical hernia. Finally, after a long time of suffering, he was diagnosed with SMAS and underwent a successful surgical operation. After 3 months of follow-up, he was in good health with no symptoms. Conclusion Whenever a patient complains of vomiting and chronic abdominal pain, intestinal obstruction is suspected, Common differential diagnoses were excluded and the cause is anonymous, we should consider superior mesenteric artery syndrome.

MELAS – an acronym for mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes – is a multiorgan disease caused by a mutation in mitochondrial DNA (mtDNA). Its clinical manifestations are highly variable; mainly stroke-like episodes, seizures, recurrent headaches, or muscle weakness. However, gastrointestinal complications such as chronic intestinal pseudo-obstruction (IPO), pancreatitis, gastroparesis and hepatopathy are also common. In this report we describe a young patient with gastrointestinal complication of MELAS which led to superior mesenteric artery syndrome (SMAS). It is rare but not surprising combination and should be considered in cases with significant weight loss and resistance to symptomatic treatment. The optimal energy support is the main pillar of the treatment.

This study aimed to determine the incidence and potential risk factors of superior mesenteric artery syndrome (SMAS) after corrective spinal surgery in patients with adult spinal deformity (ASD). In total, 102 patients (67.6 ± 8.4 years; 8 male/94 female; body mass index (BMI); 22.4 ± 3.6 kg/m2) with ASD treated by spinal correction surgery were enrolled. Preoperative and postoperative spinal parameters, including thoracolumbar kyphosis (TLK: T10-L2) and upper lumbar lordosis (ULL: L1-L4) were measured. To evaluate the potential risk factors of SMAS, the angle and the distance between the superior mesenteric artery and aorta, the aortomesenteric angle (AMA) and aortomesenteric distance (AMD), were evaluated pre- and postoperatively. Based on the postoperative AMA, AMD, and abdominal symptoms, the patients were diagnosed with SMAS. Correlations between demographic data or spinal parameters and AMA and AMD were assessed. Two (2.0%) patients were diagnosed with SMAS. Postoperative TLK significantly correlated with postoperative AMA (P = 0.013, 0.046). Postoperative ULL was significantly correlated with postoperative AMD (β = −0.27; P = 0.014). The incidence of SMAS after corrective spinal surgery in patients with ASD was 2.0%. Postoperative smaller TLK and greater ULL can be risk factors for developing SMAS. Spine surgeons should avoid overcorrection of the upper lumbar spine in the sagittal plane to prevent SMAS.

Background: Upper gastrointestinal (GI) contrast studies are frequently requested to aid superior mesenteric artery syndrome diagnosis, a rare entity. Compression of the third duodenal part is expected to be mid-to-left of the midline where the superior mesenteric artery arises from the aorta; however, a duodenal impression to the right of the midline due to normal anatomic impression by the inferior vena cava (IVC) is often encountered and frequently misdiagnosed. Objective: The purpose of this study was to determine the frequencies of (1) normal right-of-midline duodenal impressions and (2) mid-to-left of midline compressions in upper GI studies in a tertiary pediatric referral center. Materials and methods: All upper GI studies performed at our institution over 2 years were retrospectively evaluated to determine whether the duodenum had vertical duodenal impression to the right of the vertebral midline, mid-to-left of the vertebral midline, or no identifiable duodenal impression at all. Results: In total, 538 upper GI studies were included in this analysis. A total of 275 male and 247 female patients between 0 and 17 years of age (median: 6 years, range: 1 month-17 years) were included. Of 538 total upper GI studies, there were 240 studies (44.6%) with a right-of-midline impression. There were only 10 studies (1.9%) with a mid-to-left of midline compression, and 9/10 also showed a concurrent right-sided impression sign. Conclusion: Right-of-midline duodenal impression is a normal anatomic finding caused by the IVC and should not be confused with superior mesenteric artery syndrome. In the presence of an appropriate clinical context, proximal duodenal dilation, "to-and-fro" motion of contrast, and duodenal impression at mid-to-left of midline, a diagnosis of superior mesenteric artery syndrome should be considered.

This article presents a study on duodenal perforations caused by nasojejunal tubes, which are often used for temporary enteral nutrition. The study examined data from multiple centers and identified five patients who experienced perforations related to these tubes. The perforations were confirmed through computed tomography or endoscopy. The patients were treated based on the severity of their symptoms and all were asymptomatic during follow-up. The article includes specific cases of patients who suffered duodenal perforations and discusses the management and outcomes of each case. Additionally, the document discusses a case study involving a 19-year-old woman who experienced a duodenal perforation after the placement of a nasojejunal tube. Nasojejunal tubes are commonly used for temporary nutrition and can be placed blindly at the bedside or with the guidance of endoscopy or fluoroscopy. However, blind placement has a high failure rate, while endoscopic and fluoroscopic methods have shown greater success. The study suggests that selecting the appropriate tube and closely monitoring patients receiving tube feeding can help reduce the risk of complications. [Extracted from the article]
