Delayed presentation of Wilkie's syndrome after scoliotic curve correction surgery: a case report. BMC Musculoskelet Disord 2024; 25:329. [PMID: 38658916 PMCID: PMC11044465 DOI: 10.1186/s12891-024-07462-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/12/2024] [Accepted: 04/19/2024] [Indexed: 04/26/2024] Open
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.

Understanding the diagnosis of superior mesenteric artery syndrome: analysis of the location of duodenal impression on upper gastrointestinal studies. Pediatr Radiol 2023; 53:2633-2641. [PMID: 37837457 PMCID: PMC10697883 DOI: 10.1007/s00247-023-05782-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/09/2023] [Revised: 09/18/2023] [Accepted: 09/19/2023] [Indexed: 10/16/2023]
Abstract
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.

Incidence and Potential Risk Factors of Superior Mesenteric Artery Syndrome After Spinal Corrective Surgery in Patients with Adult Spinal Deformity. World Neurosurg 2023; 180:e591-e598. [PMID: 37805127 DOI: 10.1016/j.wneu.2023.09.114] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Accepted: 09/27/2023] [Indexed: 10/09/2023]
Abstract
OBJECTIVE 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). METHODS 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. RESULTS 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). CONCLUSION 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.

Abstract
PURPOSE Superior mesenteric artery syndrome (SMAS) is one of the rare causes of chronic duodenal obstruction. The aim of our study was to evaluate the outcomes of surgical management of refractory SMAS (Re-SMAS) in our institution during the last decade. MATERIALS AND METHODS Consecutive patients diagnosed as Re-SMAS and underwent surgical intervention were retrospectively enrolled. A modified Likert-scale-based questionnaire was used to quantify the symptoms of SMAS. The primary outcome was the increase of BMI and symptomatic relief after surgery. RESULTS From January 2010 to January 2020, 22 patients diagnosed with Re-SMAS and underwent surgery were included. Age distribution of included patients were < 19 (10/22, 45%), 19-45 (11/22, 50%), and > 45 (1/22, 5%). A significant BMI increase was recorded, [16.1 (14.6-23.7) kg/m2 vs 21.9 (15.6-29.5) kg/m2 before and after surgery, respectively, p < 0.001]. Up to 20 patients (20/22, 91%) reported symptomatic relief. The obstruction-related symptom score decreasing significantly (p < 0.001), with reported nausea, vomiting, and regurgitation incidences dropping from 77 to 41% (p = 0.031), 68 to 23% (p = 0.006), and 32 to 5% (p = 0.046), respectively. CONCLUSION Surgical interventions could relieve obstruction-related symptoms of Re-SMAS and promote weight gain. For patients who suffered from Re-SMAS and referred to surgeons mainly for obstruction-related symptoms, surgical intervention is recommended.

Abstract
Down syndrome is a common chromosomal abnormality, which is associated with a wide spectrum of multiorgan complications, including gastrointestinal disorders. Superior mesenteric artery syndrome is a rare type of small intestinal obstruction caused by compression of the duodenum between the superior mesenteric artery anteriorly and the abdominal aorta posteriorly. A 12-year-old boy with Down syndrome came to the emergency department with a first seizure secondary to electrolyte disturbances. He had been having recurrent episodes of bilious vomiting. Computed tomography of the abdomen revealed a markedly distended stomach and proximal duodenum with a narrow aortomesenteric angle consistent with superior mesenteric artery syndrome. The patient received successful conservative treatment with aggressive fluid resuscitation, bowel decompression, and electrolyte correction. Child protection services found that the patient had rapid weight loss recently after parents were confronted with the confirmed diagnosis of Down syndrome in their child. Physicians need to consider superior mesenteric artery syndrome in any child with an intellectual disability presenting with a clinical picture of intestinal obstruction.

Abstract
Vascular compression of the third part of the duodenum by the superior mesenteric artery results in an unusual occlusion of the duodenal transit known as superior mesenteric artery syndrome. This syndrome can occur after surgeries to correct spinal deformities in a rate ranging from 0.5% to 4.7%. It results from a positional alteration of the artery emergency point due to a change in trunk length after surgery. It is associated with risk factors such as low body mass index and weight loss. Patients usually present with intestinal occlusion, abdominal pain, nausea, bilious vomiting, and early satiety. Superior mesenteric artery syndrome must be recognized early to institute an adequate treatment, which can be clinical (with gastric tube for decompression and nutritional support) or require a surgical procedure. Secondary complications related to superior mesenteric artery syndrome include delayed surgical and nutritional recovery, healing problems, and prolonged hospitalization. The present study aims to report a case of superior mesenteric artery syndrome in a patient with neuromuscular scoliosis secondary to a transverse myelitis who underwent surgical treatment for spinal deformity correction.

Abstract
BACKGROUND Superior mesenteric artery (SMA) syndrome is a well-recognized, rare complication of undergoing surgical correction of a spinal deformity. The objective of this study was to summarize the best available evidence on SMA syndrome treatment after scoliosis surgery. To identify differences, special attention was paid to scoliosis pathology, intervention and SMA syndrome presentation. METHODS A systematic review of the literature was performed on SMA syndrome following scoliosis surgery. The Web of Science, PubMed, Wanfang (Chinese) and EMBASE databases were systematically searched for articles from January 1971 to October 2020. The main subjects discussed are scoliosis pathology, intervention and SMA syndrome presentation. RESULTS A total of 32 articles with 52 cases were included in our report. The mean age of patients with SMA syndrome following scoliosis surgery was 14.7 ± 2.9 years and the majority (n = 42, 80.8%) were girls. The most frequently reported scoliosis type was adolescent idiopathic scoliosis (n = 34, 65.4%). The mean postoperative days (POD) (interval between the surgical treatment and the onset of symptoms) was 9.6 ± 9.5 days. Different treatment methods were analyzed in 46 patients. We noted a trend toward a higher percentage of patients with POD < 48 hr in the group with surgical treatment than in the conservative treatment group (P = 0.002). CONCLUSION In summary, in this systematic review, for the first time, we found that the time of onset of postoperative symptoms can be used as an important reference index for surgical intervention. We also believe that recommendations about the treatment of SMA syndrome following scoliosis surgery should include this finding. Given the lack of robust clinical evidence, these findings warrant verification in a prospective multicenter screening trial.

Abstract
Superior mesenteric artery (SMA) syndrome is a rare but serious complication following scoliosis surgery. Early diagnosis and management are key factors for successful conservative treatment to avoid the need for emergency laparotomies which causes higher morbidity or even mortality. We report two adolescent idiopathic scoliosis patients with Cobb angle of 49° and 132°, respectively, and low body mass index who presented with SMA syndrome following posterior spinal fusion from T2 to L3 and were treated successfully with conservative management. Abdominal radiographs showed distended gastric shadow. Computed tomography angiography of the abdomen showed decreased aortomesenteric angle and SMA-aorta distance. Both patients were treated successfully with conservative treatment which included three principles: gastric decompression with nasogastric tube, correction of electrolytes imbalance, and nutritional support with low volume, high calorie nutritional supplement. Both patients were started with small but frequent meals. Surgeries were not required in both cases. Early diagnosis and management are the key factors to successful treatment in SMA syndrome. Patients with SMA can be treated successfully with conservative treatment comprising of nasogastric decompression, electrolyte correction, and nutritional support with small but frequent meals.

Abstract
BACKGROUND Patients with neuromuscular scoliosis (NMS) who undergo posterior spinal fusion (PSF) often have long, protracted hospital stays because of numerous comorbidities. Coordinated perioperative pathways can reduce length of hospitalization (LOH) without increasing complications; however, a subset of patients may not be suited to rapid mobilization and early discharge. METHODS 197 patients with NMS underwent PSF at a single hospital by two surgeons with a post-operative care pathway emphasizing early mobilization, rapid transition to enteral feeds, and discharge prior to first bowel movement. Average LOH was 4.9 days for all patients. Patients were divided into quartiles (< 3 days, 3-5 days, 5-7 days, > 7 days) based on their LOH, and their charts were retrospectively reviewed for preoperative, intraoperative, and postoperative factors associated with their LOH. RESULTS Age at surgery, gender, the need for tube feeds, and specific underlying neuromuscular disorder were not significant predictors of LOH; however, severely involved cerebral palsy (CP) patients (GMFCS 4/5) were more likely to have extended stays than GMFCS 1-3 patients (p = 0.02). Radiographic predictors of LOH included major coronal Cobb angle (p = 0.002) and pelvic obliquity (p = 0.02). Intraoperative predictors included longer surgical times, greater numbers of levels fused and need for intraoperative or postoperative blood transfusion (p < 0.05). The need for ICU admission and development of a pulmonary complication were significantly more likely to fall into the extended LOH group (p < 0.05). CONCLUSIONS Several variables have been identified as significant predictors of LOH after PSF for NMS in the setting of a standardized discharge pathway. Patients with smaller curves and less complex surgeries were more amenable to accelerated discharge. Conversely, patients with severe CP with large curves and pelvic obliquity requiring longer surgeries with more blood loss may not be ideal candidates. These data can be used to inform providers' and families' post-operative expectations. LEVEL OF EVIDENCE Therapeutic Level III.

Abstract
CASE A 13-year-old female presenting with untreated congenital scoliosis underwent single-stage anterior plus posterior deformity correction surgery. On the sixth postoperative day, she started vomiting and complained of abdominal pain. Imaging studies suggested superior mesenteric artery syndrome (SMAS). Conservative treatment for 3 weeks yielded no improvement in symptoms. She subsequently underwent laparoscopic duodenojejunostomy, which resolved her symptoms. CONCLUSIONS SMAS, although rare, is a morbid complication of deformity correction surgery. Medical management is the treatment of choice, with surgery reserved for nonresponders. Prompt diagnosis and appropriate intervention can provide effective treatment, thus preventing catastrophic consequences.

Abstract
This review is directed at increasing awareness of two diverse rare upper gastrointestinal problems that occur at opposite ends of the age spectrum and are difficult to diagnose and treat. The Superior Mesenteric Artery Syndrome (SMAS) likely involves a young patient, especially female, and is especially associated with rapid weight loss, resulting in relative strangulation of the duodenum by a narrowing of the angle between the Superior Mesenteric Artery (SMA) and the aorta. On the other hand, atherosclerosis of the SMA is associated most likely with postprandial upper intestinal ischemia and abdominal pain occurs in the elderly at high risk for cardiovascular (CV) disease. Medical management of the SMAS in the young involves good alimentation and weight gain to overall increase the intestinal fat pad. Medical management of SMA atherosclerotic ischemia in the elderly is directed at marked lipid lowering with atherosclerotic plaque stabilization or even regression. If needed, surgery for SMAS can be attempted laparoscopically with duodenojejunoscopy which is the most popular procedure but there are also more conservative possibilities that avoid division of the duodenum. In addition, sometimes direct vision is needed to successfully operate on SMAS. If surgery is needed for SMA atherosclerotic ischemia, it is usually attempted endoscopically with angioplasty and stent placement. Most important, in the case of these two rare clinical entities, is that the clinician have a suspicion of their presence when indicated so that the young or old patient can be spared unnecessary suffering and return to good health in a timely fashion.

Abstract
Introduction Perioperative complications associated with spinal fusion have been investigated steadily to reduce morbidity and mortality. Although there are several reports reviewing abdominal complications occurring with anterior spinal fusion, complications related to posterior spinal fusion (PSF) are rare. However, abdominal compartment syndrome (ACS) after PSF could be the most fatal and unpredictable complication in spinal surgery. Case presentation This 73-year-old man with body mass index (BMI) of 23.02, and surgical history of appendectomy 10 years prior complained of severe nausea and vomiting on the second postoperative day of L4-5 transforaminal lumbar interbody fusion (TLIF). By postoperative day 4, he presented with dyspnea and fever, and the first diagnostic impression suggested aspiration pneumonia due to vomiting. Physical examination revealed severe abdominal distention and tenderness to palpation at most of the abdomen. Computed tomography (CT) scan of abdomen and chest revealed left inguinal hernia of the small bowel with incarceration suggesting intra-abdominal hypertension (IAH), and multifocal peri-bronchial consolidation in both lungs, respectively. His respiratory symptoms progressed to respiratory failure, and he was finally mechanically ventilated in conjunction with antibiotics. After 2 weeks of intensive care, the patient's symptom had improved, and finally he was transferred to a nursing facility. Discussion IAH and ACS rarely occur as abdominal complications of PSF. We suggest several risk factors including body mass index, abdominal surgical history, and long segment fusion for development of abdominal complications.

Abstract
BACKGROUND Superior mesenteric artery syndrome (SMAS) occurs when the duodenum is compressed between the two arteries, superior mesenteric artery and aorta. The complications of this rarely found disorder in children range from causing trouble in duodenal functions to intestinal obstruction which is potentially life-threatening. CASE PRESENTATION Here we are reporting a case of SMAS in a 6-year-old girl with the complaint of chronic abdominal pain since 3 years. She suffered from growth failure, while different workups were negative. Ultimately, imaging investigations detected superior mesenteric artery syndrome as an etiologic background. In the additional investigations, it is found that she suffered from celiac disease. CONCLUSION We concluded that the inflammatory nature of the celiac disease can affect the anatomy of the duodenum beyond its mucosal surface in the mesenteric fat tissue and results in SMAS.

Abstract
Introduction: Obstruction of the third part of duodenum by superior mesenteric artery is known as superior mesenteric artery syndrome. Incidence of superior mesenteric artery syndrome following spine deformity correction is 0.5–4.7%. Till now, this syndrome after isolated kyphosis correction with vertebral column resection is rarely reported in literature. Case Report: A 17-year-old male patient with normal body habitus presented with 80° of congenital thoracolumbar kyphosis. He underwent kyphosis correction with vertebral column resection and posterior instrumentation and posterior spinal fusion under neuro monitoring. Deformity correction was excellent; the patient was alright in immediate post-operative period. 2 weeks after surgery presented with repeated vomiting and abdominal pain. Contrast computed tomography was showing decreased aortomesenteric angle and decreased aortomesenteric distance which confirmed the diagnosis of superior mesenteric artery syndrome. Initial management was conservative, but as symptoms were progressive, duodenojejunostomy was done. The patient was completely recovered from obstructive symptoms. Conclusion: Superior mesenteric artery syndrome is a life-threatening complication that can occur after spine deformity correction. Early recognition and appropriate measures are critical to prevent the development of severe complications including death.

Abstract
Superior mesenteric artery (SMA) syndrome secondary to extrinsic compression of third part of duodenum is an uncommon complication following scoliosis surgery. It is imperative to diagnose this presentation at an earlier stage as it can be a potentially life threatening complication. If the diagnosis is missed or delayed, the mortality rate can be as high as 33% due to fatal complications like aspiration pneumonia, acute gastric rupture and cardiovascular collapse. We present a 13-year-old patient who was diagnosed with SMA syndrome in the late post-operative period (5.1 weeks) following scoliosis correction surgery. A barium meal and follow-through confirmed the diagnosis of SMA syndrome. She was managed conservatively with which she recovered uneventfully. Such late presentations are very uncommon. In addition, we have also briefly reviewed the pertinent literature. It is essential that we identify high risk patients preoperatively so that we could optimize them with proper intensive dietary supplementation. Postoperatively, a high index of suspicion needs to be retained to identify this syndrome at an early stage so that conservative management may be initiated with good clinical outcome. SMA syndrome can be potentially life threatening when the diagnosis is missed or delayed.

Abstract
Vascular complications are an important adverse event that can be associated with spinal reconstructive surgery. Direct injury of vessels, or indirect traction or compression of vessels, can cause both arterial and venous injury. Indirect compression of the mesenteric vessels is a well-recognized complication of bracing and surgical care of children with spinal deformity (superior mesenteric artery syndrome), but the complication is not common or well recognized in the adult population with spinal deformity. The purpose of this case report is to detail the case of postoperative mesenteric ischemia in a 63-year-old man in whom a posterior approach was used to perform spinal deformity correction. Preoperatively, the patient had had significant lumbar hypolordosis. The reconstructive surgery with the use of posterior-based osteotomies resulted in a shortening of the posterior column of the spine but a relative lengthening of structures anterior to the spine. The significant lordosis achieved by the surgery led to an acute worsening of the mesenteric stenosis suffered by the patient. He required a vascular surgery intervention to restore perfusion to the bowel. Recognition of severe vasculopathy is important in anticipating potential postoperative vascular insufficiency. This case report will inform surgeons and clinicians to have a higher index of suspicion for the exacerbation of vascular insufficiency, including mesenteric pathology, in patients undergoing surgery that involves significant realignment of the spine. Preoperative recognition of vascular insufficiency and treatment of symptomatic disease may limit the occurrence of postoperative vascular complications in spinal reconstructive surgery.

Abstract
Background. An obstruction of the distal part of the duodenum can occur because of the superior mesenteric artery syndrome (SMAS) after a surgical correction of scoliosis. It is essential to evaluate the risk factors and diagnose the SMAS in time because complications of this condition are life-threatening and it is associated with a high rate of morbidity. Diagnostics of the SMAS is challenging, because it is rare and its symptoms are non-specific. Therefore, in order to better understand the essence of this pathology and to make diagnosis easier we present a rare clinical case of the superior mesenteric artery syndrome after a surgical correction of neuromuscular scoliosis. The clinical case. A 12-year-old girl with a specific development disorder, sensory neuropathy and progressive kypho-scoliosis was admitted to Vilnius University Children’s Hospital. The patient had right side 50-degree thoracic scoliosis and an 80-degree thoracic kyphosis. She underwent posterior spinal fusion with hooks and screws from Th1 to L2. On the fourth day after the surgery the patient developed nausea and began to vomit each day 1-2 times per day, especially after meals. The SMAS was suspected and a nasogastric tube was inserted, stomach decompression and the correction of electrolytes disbalance were made. After the treatment, the symptoms did not recur and a satisfactory correction and balance of the spine were made in coronal and sagittal planes. Conclusions. It is extremely important to identify the risk factors of the SMAS and begin preoperative diet supplements before surgical correction of scoliosis for patients with a low body mass index. After the first episode of vomiting following the surgery, we recommend to investigate these patients for a gastrointestinal obstruction as soon as possible. Decompression of the stomach, enteral or parenteral nutrition, and fluid therapy are essential in treating the SMAS.

Abstract
The superior mesenteric artery syndrome (SMAS) is an uncommon condition in children. We describe a case of a 7-year-old boy with SMAS that occurred 3 years after a Deloyers' procedure for subtotal colonic Hirschsprung who was admitted for bilious vomit, abdominal pain and diarrhea due to unrecognized celiac disease. This case emphasize that SMAS in children needs a close medical and surgical follow-up to avoid an underestimation of early clinical signs unrelated to surgery.

Abstract
Superior mesenteric artery syndrome is a rare condition that causes a proximal small intestinal obstruction due to contraction of the angle between the superior mesenteric artery and the aorta. Scoliosis surgery is one of the 15 reasons for superior mesenteric artery syndrome, which can present with acute or chronic manifestations. Although conservative treatment is usually possible, surgical treatment is required in certain cases that cannot be treated using conservative methods. In this paper, we describe a patient who developed superior mesenteric artery syndrome after scoliosis surgery and was treated with duodenojejunostomy due to failure and complications of conservative treatment.

Abstract
STUDY DESIGN A computed tomographic study. OBJECTIVE To investigate the changed anatomic relationship between the superior mesenteric artery and the aorta in surgically treated ankylosing spondylitis (AS) patients with thoracolumbar kyphosis. SUMMARY OF BACKGROUND DATA Superior mesenteric artery syndrome in kyphosis patients after surgery has been reported. To date, the changed aortomesenteric angle and distance in AS patients undergoing surgical correction of kyphosis have not yet been addressed. METHODS Thirty-three AS patients with thoracolumbar kyphosis subjected to pedicle subtraction osteotomy were prospectively recruited. Radiographic measurements included global kyphosis (GK), thoracic kyphosis (TK), local kyphosis (LK), and lumbar lordosis. The aortomesenteric angle and distance were measured on both preoperative and postoperative computed tomography images. The height and weight of these patients were also recorded. RESULTS The average height significantly increased from 159.7±5.1 cm before surgery to 167.2±5.3 cm after surgery (P<0.001), whereas the average weight changed from 59.3±6.8 kg to 59.5±6.9 kg (P>0.05). GK, TK, LK, and lumbar lordosis were corrected from 77.7, 40.2, 19.4, and 2.8 degrees before surgery to 37.1, 38.4, -21.9, and -32 degrees after surgery, respectively. All the changes of these parameters were found to be significantly different (P<0.001) except that of TK (P>0.05). With the correction of kyphosis, the aortomesenteric angle significantly decreased from 29.3 to 23.4 degrees (P<0.001), whereas the aortomesenteric distance significantly decreased from 25.7 to 20.4 mm (P<0.001). It is to be noted that the changes of GK, LK, and height were significantly correlated with the decrements of aortomesenteric angle and distance (P<0.05). CONCLUSIONS The correlations of the surgical correction of kyphosis and the decreased aortomesenteric angle and distance in AS patients were quantitatively confirmed by our study. Spine surgeons should be aware of the potential risk for the development of superior mesenteric artery syndrome after kyphosis correction in AS patients.

Abstract
Ogilvie's syndrome is a rare and potentially fatal disease that can easily be mistaken for postoperative ileus. Also known as acute colonic pseudo-obstruction, early recognition and diagnosis of the syndrome allows for treatment prior to bowel perforation and requisite abdominal surgery. The authors report a case of Ogilvie's syndrome following spinal deformity correction and tethered cord release in an adolescent who presented with acute abdominal distension, nausea, and vomiting on postoperative Day 0. The patient was initially diagnosed with adynamic ileus and treated conservatively with bowel rest, reduction in narcotic dosage, and a regimen of stool softeners, laxatives, and enemas. Despite this treatment, her clinical course failed to improve, and she demonstrated significant colonic distension radiographically. Intravenous neostigmine was administered as a bolus with a rapid and dramatic response. This case is the first reported instance of neostigmine use for Ogilvie's syndrome treatment following a pediatric neurosurgical operation.

Abstract
We report Ogilvie's syndrome following posterior spinal arthrodesis on a patient with thoracic and lumbar scoliosis associated with intraspinal anomalies. Postoperative paralytic ileus can commonly complicate scoliosis surgery. Ogilvie's syndrome as a cause of abdominal distension and pain has not been reported following spinal deformity correction and can mimic post-surgical ileus. 12 year old female patient with double thoracic and lumbar scoliosis associated with Arnold-Chiari 1 malformation and syringomyelia. The patient underwent posterior spinal fusion from T4 to L3 with segmental pedicle screw instrumentation and autogenous iliac crest grafting. She developed abdominal distension and pain postoperatively and this deteriorated despite conservative management. Repeat ultrasounds and abdominal computer tomography scans ruled out mechanical obstruction. The clinical presentation and blood parameters excluded toxic megacolon and cecal volvulus. As the symptoms persisted, a laparotomy was performed on postoperative day 16, which demonstrated ragged tears of the colon and cecum. A right hemi-colectomy followed by ileocecal anastomosis was required. The pathological examination of surgical specimens excluded inflammatory bowel disease and vascular abnormalities. The patient made a good recovery following bowel surgery and at latest followup 3.2 years later she had no abdominal complaints and an excellent scoliosis correction. Ogilvie's syndrome should be included in the differential diagnosis of postoperative ileus in patients developing prolonged unexplained abdominal distension and pain after scoliosis correction. Early diagnosis and instigation of conservative management can prevent major morbidity and mortality due to bowel ischemia and perforation.

Abstract
We report the case of a 14-year-old boy with pectus excavatum and mild scoliosis. The patient underwent a minimally invasive Nuss repair with excellent cosmetic result. He returned 3 weeks post-operatively with bilious emesis and a 3.6-kg weight loss (5.5% of total body weight). Radiographic evaluation was consistent with the diagnosis of superior mesenteric artery syndrome and the child ultimately required nasojejunal feedings. Following return to his baseline weight, he was transitioned to oral feedings and has done well in follow-up. This is the first report of SMA syndrome following minimally invasive pectus excavatum repair.

Abstract
Perioperative abdominal complications associated with spine surgery are rare. Although most known abdominal complications occur in conjunction with anterior spinal fusions, there is a paucity of reports reviewing abdominal complications occurring with posterior spinal fusions. The authors review 4 patients who experienced a perioperative abdominal complication following a posterior spinal fusion. In each of these patients, a history of abdominal surgery is present. Given the physiological changes that occur with surgery in the prone position, patients with previous abdominal surgeries are at risk for developing abdominal complications in the perioperative period.

Abstract
Superior mesenteric artery (SMA) syndrome is an infrequent cause of vomiting and weight loss due to compression of the third part of the duodenum by the SMA. We describe the case of a 17-year-old woman, admitted to our department for progressive dysphagia and severe weight loss due to an oesophageal peptic stricture, caused by chronic acid reflux secondary to duodenal compression by the SMA. Symptoms improved after (par)enteral nutrition and repeated oesophageal dilatation, thus supporting the role of intensive medical and endoscopic intervention as an alternative to surgery, at least in some cases.

Abstract
STUDY DESIGN Literature review of complications unrelated directly to surgical skills involved in spinal deformity surgery. OBJECTIVE Highlight complications associated with perioperative issues. SUMMARY OF BACKGROUND DATA Complications can arise from mundane events that arise during the operative experience, but are not directly related to surgical skills. METHODS Literature reviews that touches on the more common potential complication events that do not involve direct surgical expertise. RESULTS The topics of positioning, nutrition, blood loss, comorbidities, OR time, and pulmonary and GI concerns are discussed as basics that could derail a surgical outcome even with an otherwise uneventful surgical technique. The need for vigilance is stressed and the nuances of understanding these are discussed. CONCLUSION Mundane events can derail a perfectly executed surgical undertaking. Attention to detail, team work, close monitoring, and checklist type focus will help to improve, focus, and avoid these preventable complications that have nothing to do with direct surgical skills.

Abstract
Superior mesenteric artery syndrome is obstruction of the third portion of the duodenum by compression between the abdominal aorta and superior mesenteric artery. Pediatric orthopedists are familiar with this entity, as the association between superior mesenteric artery syndrome and spinal fusion or body casting has been well established. However, patients with spinal deformities usually experience superior mesenteric artery syndrome after orthopedic intervention, with rates after corrective spinal surgery reported between 0.5% and 2.4%. Symptoms of superior mesenteric artery syndrome typically include nausea, bilious emesis, abdominal pain, early satiety, and anorexia. Initial treatment focuses on gastric decompression and maintaining euvolemia and electrolyte balance. The patient should receive enteral nutrition via nasojejunal tube or parenteral nutrition to allow for weight gain and subsequent resolution of the obstruction. The superior mesenteric artery takes off from the duodenum at an angle of 45 degrees to 60 degrees in normal individuals. The third portion of the duodenum is suspended between these vessels by the ligament of Treitz. Any variation in this relationship that decreases the arteriomesenteric angle may induce obstruction. Specifically, lumbar hyperextension or hyperlordosis can traction the mesentery and vessels. Only 2 cases of superior mesenteric artery syndrome in patients with sagittal plane spinal deformity have been described in the literature. In patients with concomitant superior mesenteric artery syndrome and spinal deformity, correction of the deformity may help alleviate the obstruction and result in faster recovery. The contribution of spinal column deformity to the arteriomesenteric angle should not be overlooked.

Abstract
Wilkie syndrome or superior mesenteric artery syndrome is a rare cause of duodenal obstruction in pediatric and adult age groups. Its manifestations are due to compression of the third portion of the duodenum between the aorta and the superior mesenteric artery. We present one case of a 29-year-old female with a recent history of epigastric pain and severe weight loss due to duodenal obstruction from superior mesenteric syndrome. She was treated conservatively with jejunostomy tube feeding to regain loss of weight. Our case is unique in that the patient has also nutcracker syndrome.

Abstract
Superior mesenteric artery (SMA) syndrome is an unusual form of duodenal obstruction. Complications of SMA syndrome may sometimes develop and are usually associated with marked gastric dilatation, although most complications can be corrected by supportive treatment. In this article, we report a case of severe SMA syndrome with hypovolemic shock in a 24-year-old man. Multidetector-row computed tomography with reconstructed images was performed to establish the diagnosis. Spontaneous gastrointestinal bleeding is an extremely uncommon complication of SMA syndrome, and emergent surgical intervention was unavoidable in our patient. To our knowledge, no other such case has been reported in the English-language literature.

Abstract
Study Design Retrospective study. Purpose To more accurately determine the incidence and clarify risk factors. Overview of Literature Superior mesenteric artery syndrome is one of the possible complications following correctional operation for scoliosis. However, when preliminary symptoms are vague, the diagnosis of superior mesenteric artery syndrome may be easily missed. Methods We conducted a retrospective study using clinical data from 118 patients (43 men and 75 women) who underwent correctional operations for scoliosis between September 2001 and August 2007. The mean patient age was 15.9 years (range 9~24 years). The risk factors under scrutiny were the patient body mass index (BMI), change in Cobb's angle, and trunk length. Results The incidence of subjects confirmed to have obstruction was 2.5%. However, the rate increased to 7.6% with the inclusion of the 6 subjects who only showed clinical symptoms of obstruction without confirmative study. The BMI for the asymptomatic and symptomatic groups were 18.4±3.4 and 14.6±3, respectively. The change in Cobb's angle for the asymptomatic and symptomatic groups were 24.8±13.6° and 23.4±9.1°, respectively. The change in trunk length for the asymptomatic and symptomatic groups were 2.3±2.1 cm and 4.5±4.8 cm, respectively. Differences in Cobb's angle and the change in trunk length between the two groups did not reach statistical significance, although there was a greater increase in trunk length for the symptomatic group than for the asymptomatic group. Conclusions Our study shows that the incidence of superior mesenteric artery syndrome may be greater than the previously accepted rate of 4.7%. Therefore, in the face of any early signs or symptoms of superior mesenteric artery syndrome, prompt recognition and treatment are necessary.

Abstract
INTRODUCTION Obstruction of the third part of the duodenum by the superior mesenteric artery (SMA) can occur following surgical correction of scoliosis. The condition most commonly occurs in significantly underweight patients with severe deformities during the first few days to a week following spinal surgery. CASE PRESENTATION We present the atypical case of a patient with normal body habitus and a 50 degrees adolescent idiopathic thoracolumbar scoliosis who underwent anterior spinal arthrodesis with instrumentation and developed SMA syndrome due to progressive weight loss several weeks postoperatively. The condition manifested with recurrent vomiting, abdominal distension, marked dehydration, and severe electrolyte disorder. Prolonged nasogastric decompression and nasojejunal feeding resulted in resolution of the symptoms with no recurrence at follow-up. The spinal instrumentation was retained and a solid spinal fusion was achieved with good spinal balance in both the coronal and sagittal planes. CONCLUSION SMA syndrome can occur much later than previously reported and with potentially life-threatening symptoms following scoliosis correction. Early recognition of the condition and institution of appropriate conservative measures is critical to prevent the development of severe complications including the risk of death.

Abstract
We carried out a retrospective analysis to investigate the prevalence of superior mesentery artery syndrome (SMAS) in children who underwent scoliosis surgical repair at our hospital between 1998 and 2006 and to reassess the syndrome's pathogenesis. Among 133 consecutive pediatric patients, two cases were identified, both 13-year-old girls with idiopathic scoliosis, undergoing surgery using third-generation instrumentation systems. Conservative management achieved resolution of the symptoms without recurrence. SMAS prevalence in our series was 1.6%. SMAS might occur after derotation and translation forces application, and even with nonextreme corrections. Low BMI and significant weight loss at presentation are not mandatory.

Abstract
In 1861, von Rokitansky described obstruction of the third part of the duodenum by external compression of the duodenum by the superior mesenteric artery (SMA). In 1926, this entity was furthermore described by Wilke in his presentation of 75 patients with “chronic duodenal compression”. In 1968, Mansberger used angiography to define anatomical measurements as the diagnostic criteria for this condition. Current modalities of diagnosis of SMA syndrome include esophagogastroduodenoscopy, computerized tomography angiogram, fluoroscopy, transabdominal ultrasound, and endoscopic ultrasound. The SMA syndrome has been associated with prolonged confinement in the supine position, loss of weight, loss of abdominal wall muscle tone, application of a body cast, and severe burns. With current surgical techniques allowing early ambulation, patients are able to avoid prolonged bed rest. The use of parenteral and enteral nutritional support has limited the loss of weight associated with trauma and burn patients, making this syndrome uncommon in this patient population. Recent reports of SMA syndrome focus on the association with corrective surgical procedures for scoliosis and obesity.

Abstract
Superior mesenteric artery syndrome (SMAS) is a rare complication following correction of scoliosis with either nonoperative or operative methods. If the patient diagnosed with this syndrome is not managed timely and adequately, mortality may result. We report two cases of SMAS complicating staged corrective surgery for scoliosis using modern segmental derotation instrumentation system. The aim of this report is to highlight the clinical presentations, laboratory findings, radiologic features, and management of the syndrome. The first patient had the syndrome after two-staged scoliosis surgery with halo traction between two stages, and the second patient after three-staged scoliosis surgery with halo traction between the first and second surgeries. The first patient responded well to conservative treatment. However, the second patient failed to respond to conservative treatment and needed a gastrojejunostomy operation to bypass the duodenal obstruction. Clinicians treating post scoliosis surgery patients should always have a high index of suspicion for this potential life-threatening condition. Early diagnosis will enable a multidisciplinary team approach to be initiated early to provide optimal care for the patient. Nutritional and fluid supplementation is mandatory during conservative treatment. The duration for trial of conservative treatment should not exceed 1 week.

STUDY DESIGN Review article of medical complications related to adult spinal deformity surgery. OBJECTIVE To identify medical complications related to surgery for adult spinal deformity and suggest ways to minimize their occurrence and to avoid them. SUMMARY OF BACKGROUND DATA Medical complications are a major consideration in adult spinal deformity surgery. Few studies have been done to identify the medical complication rate in relation to these procedures. METHODS We review the literature pertaining to medical complications regarding spinal deformity surgery. RESULTS Urinary tract infections are the most frequently seen complication. Additionally, pulmonary complications are the most common life-threatening complication. Medical complications are a frequent occurrence with adult deformity spinal surgery. CONCLUSIONS Awareness of the presentation, treatment, and prevention of medical complications of deformity surgery may allow minimization of their occurrence and optimize treatment should they occur.

Abstract
OBJECTIVES Superior mesenteric artery syndrome (SMAS), Wilkie syndrome or cast syndrome is a rare condition that usually presents with symptoms of mid to upper gastrointestinal obstruction due to the compression of the duodenum between the abdominal aorta, posteriorly, and the superior mesenteric artery, anteriorly. The aim of this study was to analyze the clinical characteristics, means of diagnosis and management of SMAS in a pediatric population. METHODS Retrospective chart review of all patients at the Children's Hospital of Wisconsin with SMAS from 1985 to 2005. RESULTS Twenty-two cases of SMAS where diagnosed at Children's Hospital of Wisconsin between 1985 and 2005 [14, (64%) female]. Symptoms developed 1 to 393 days (median 5 days) before diagnosis. Presenting symptoms included abdominal pain (59%), vomiting (50%), nausea (40%), early satiety (32%) and anorexia (18%). Diagnosis was made by upper-gastrointestinal radiography in 18 (82%), by computed tomography in 2 (9%) and at laparotomy in 2 (9%). One patient was treated surgically after medical management failed. Mean length of treatment was 65 days (range 13-169), with a mean length of hospitalization of 21 days (range 0-68 days). CONCLUSION SMAS usually presents more acutely than chronically with symptoms of small bowel obstruction. Weight loss is not necessary for SMAS development. Prior neurological injury may be a risk factor for development of SMAS. Upper gastrointestinal radiography remains the primary means of diagnosis. SMAS is typically successfully managed medically. Surgical intervention should be reserved for patients' refractory to medical therapy. The expected outcome of SMAS is excellent.

STUDY DESIGN A retrospective review. OBJECTIVE To determine the incidence of the superior mesenteric artery syndrome (SMAS) after surgical correction for scoliosis and if it is influenced by newer derotation/translation surgical systems. SUMMARY OF BACKGROUND DATA The SMAS is a known complication after surgery. METHOD Of 2939 charts reviewed, 17 patients between 1960 and 2002 matched inclusion criteria. RESULTS Our incidence of the SMAS was 0.5%. Onset of symptoms was 7.2 days. Several scoliosis diagnoses were included in the study group. Instrumentation that was used included: nondistraction systems (n = 14), Harrington rod with body cast (n = 1), Luque rod with sublaminar wires (n = 1), and casted in situ posterior spinal fusion (n = 1). Before surgery, 10 of 17 patients weighed less than the 50th percentile. Mean preoperative BMI was 18.6 kg/cm/cm. Postoperative height gain averaged 3.175 cm, and weight loss at onset of symptoms averaged 4.5 kg. There were 14 patients who required nasogastric suction for an average duration of 10.2 days, 11 required hyperalimentation, and 5 concurrently received hyperalimentation with enteric feeding. The SMAS recurred in 2 patients. CONCLUSIONS Postoperative weight loss appears to be more important for the development of the SMAS than asthenic body type. Newer derotation/translation corrective techniques have not eliminated the SMAS. Gastrointestinal imaging is indicated when nausea and vomiting occur 6-12 days after surgery, associated with early satiety and normal bowel sounds. Decompression and nutritional support remain the mainstays of treatment.

Abstract
AIM: To investigate the risk indicators, pattern of clinical presentation and treatment strategy of superior mesenteric artery syndrome (SMAS) after scoliosis surgery.
METHODS: From July 1997 to October 2003, 640 patients with adolescent scoliosis who had undergone surgical treatment were evaluated prospectively, and among them seven patients suffered from SMAS after operation. Each patient was assigned a percentile for weight and a percentile for height. Values of the 5th, 10th, 25th, 50th, 75th, and 95th percentiles were selected to divide the observations. The sagittal Cobb angle was used to quantify thoracic or thora-columbar kyphosis. All the seven patients presented with nausea and intermittent vomiting about 5 d after operation. An upper gastrointestinal barium contrast study showed a straight-line cutoff at the third portion of the duodenum representing extrinsic compression by the superior mese-nteric artery (SMA).
RESULTS: The value of height in the seven patients with SMAS was above the mean of sex- and age-matched normal population, and the height percentile ranged from 5% to 50%. On the contrary, the value of weight was below the mean of normal population with the weight percentile ranging from 5% to 25%. Among the seven patients, four had a thoracic hyperkyphosis ranging from 55° to 88° (average 72°), two had a thoracolumbar kyphosis of 25° and 32° respectively. The seven patients were treated with fasting, antiemetic medication, and intravenous fluids infusion. Reduction or suspense of traction was adopted in three patients with SMAS during halo-femoral traction after anterior release of scoliosis. All the patients recovered completely with no sequelae. No one required operative intervention with a laparotomy.
CONCLUSION: Height percentile<50%, weight percentile<25%, sagittal kyphosis, heavy and quick halo-femoral traction after spinal anterior release are the potential risk indicators for SMAS in patients undergoing correction surgery for adolescent scoliosis.
