Yuda Handaya, Mukhamad Sunardi
Because most surgeons perform an esophagectomy and colonic transposition as the main reconstruction method for patients with esophageal stenosis caused by swallowing corrosive materials, we report 2 cases in which ileocolonic transposition was used to treat such patients. Both patients displayed stenosis in the middle third of the esophagus. Their chief complaint was dysphagia. Ileocolonic transposition using vascularization of the Drummond and ileal arteries was followed by a prepared ileocolic graft by ligating ileocolic vessels...

BACKGROUND: In order to identify any changes in the utilization of new and old techniques, we investigated trends in the operative management of cervical stenosis by orthopaedic surgeons applying for board certification. METHODS: We queried the American Board of Orthopaedic Surgery database from 1998 to 2013 to identify all of the cervical spine procedures for stenosis that had been performed by candidates taking Part II of the licensing examination. Longitudinal trends were determined for the utilized approach, the individual procedures that had been performed, and whether a motion-preserving technique had been employed...

Depending on the adequacy of collateral sources of blood flow, arterial stenosis or occlusion may lead to reduced perfusion pressure and ultimately reduced blood flow in the distal territory supplied by that vessel. There are two well-defined compensatory mechanisms to reduced pressure or flow - autoregulatory vasodilation and increased oxygen extraction fraction. Other changes, such as metabolic downregulation, are likely. The positive identification of autoregulatory vasodilation and increased oxygen extraction fraction in humans is an established risk factor for future ischemic stroke in some disease states such as atherosclerotic carotid stenosis and occlusion...

BACKGROUND: Very little is known about the incidence and prevalence of hydrocephalus in patients with mucopolysaccharidoses (MPS). The biggest challenge is to distinguish communicating hydrocephalus from ventricular dilatation secondary to brain atrophy, because both conditions share common clinical and neuroradiological features. The main purpose of this study is to assess the relationship between ventriculomegaly, brain and cerebrospinal fluid (CSF) volumes, aqueductal and cervical CSF flows, and CSF opening pressure in MPS patients, and to provide potential biomarkers for abnormal CSF circulation...

Objective With the implementation of the K-DOQI guidelines, more patients are in need of long-term dialysis catheters until maturation of the arteriovenous fistula. However, on occasion, when placing a tunneled cuffed catheter for hemodialysis, we have encountered difficulty with passing the guidewire in spite of demonstration of a patent cervical portion of the internal jugular vein on duplex. Herein, we review our experience with intraoperative venoplasty for placement of Tesio™ catheters (Medcomp Harleysville, PA)...

OBJECTIVE: Spontaneous cervical artery dissection (CAD) is a cerebrovascular disease typically considered to affect the young population. Literature reports cases in the elderly only as incidental findings, making the diagnosis unlikely in older patients. Incidence and pathogeny in this specific population remain to be assessed. METHODS: We reviewed patients aged over 70 years admitted for spontaneous CAD in the Stroke Unit of the University Hospital of Nancy (northeastern France) over a period of 12 years as well as all reported cases in literature...

BACKGROUND AND PURPOSE: Osteoarticular manifestations of beta-2 microglobulin amyloidosis are often diagnosed in long-term dialyzed patients. However, spinal involvement is rare (10-25% of patients), and generally not associated with neurological deterioration. Compression of the spinal cord or roots is extremely rare, and probably under-recognized. METHODS: The authors describe three cases of spinal stenosis presenting with neurological signs in long-term dialyzed patients, prospectively collected over 2 years in two different institutions and treated by surgical decompression...

BACKGROUND CONTEXT: Conventional laminoplasty is useful for expanding a stenotic spinal canal. However, it has limited use for the decompression of accompanying neural foraminal stenosis. As such, an additional posterior foraminotomy could be simultaneously applied, although this procedure carries a risk of segmental kyphosis and instability. PURPOSE: The aim was to elucidate the long-term surgical outcomes of additional posterior foraminotomy with a laminoplasty for cervical spondylotic myelopathy (CSM) with radiculopathy...

To assess changes of menstrual patterns, their causes, preventions and treatment methods after abdominal radical trachelectomy (ART), we recorded patients' menstrual patterns after surgery and compared them with the conditions before surgery. Patients were divided into 3 groups based on their menstrual status post-trachelectomy:Group 1: menstrual patterns unchanged; Group 2: menstrual patterns changed without amenorrhea; and Group 3: amenorrhea. One hundred and twenty-nine patients were included: 39 (30.2%) women belonged to Group 1, 74 (57...

Low back pain (LBP) in patients with rheumatoid arthritis (RA) has so far been of little concern in clinical investigations. The main focus of scientific publications on spinal problems in RA was the cervical spine. In a recent study, we could demonstrate that LBP in RA patients leads to a significantly higher degree of disability and depression as well as to a reduction in quality of life compared to RA patients without LBP. If there is a specific reason for the additional symptom of LBP, such as spinal stenosis or segmental instability, surgical treatment may be indicated to improve disability and quality of life...

BACKGROUND: Tandem spinal stenosis refers to spinal canal diameter narrowing in at least 2 distinct regions of the spine, most commonly the lumbar and cervical regions. This entity can be an asymptomatic radiographic finding, or it can present with severe myelopathy and lower-extremity symptoms. Tandem spinal stenosis may impact surgeon decision-making when planning either cervical or lumbar spine surgery, and there is currently no consensus in the literature regarding the treatment algorithm for operative intervention...

A 57-year-old man with insidious onset of progressive bilateral upper extremity weakness was referred to physical therapy by his primary care physician. Following examination, the physical therapist referred the patient back to his primary care physician with a request for cervical magnetic resonance imaging (MRI) and neurology consultation. Cervical radiographs demonstrated multilevel degenerative changes, while cervical spine MRI revealed compressive myelopathy, significant spinal canal stenosis, and severe spondylosis J Orthop Sports Phys Ther 2017;47(9):691...

Combined upper cervical canal stenosis and cervical ossification of the posterior longitudinal ligament (OPLL) is an under-recognized disorder. The objective of the present study was to investigate the radiological manifestations and surgical outcomes of this disease combination. Between May 2011 and July 2014, we studied the radiological manifestations of 18 cases of combined upper cervical canal stenosis and cervical OPLL. Appropriate decompression procedures were performed and the clinical outcomes were evaluated using a visual analog scale (VAS) and the Japanese Orthopedic Association (JOA) scoring system...

BACKGROUND: Although cervical spondylosis is extremely common, only few cases with associated syrinx have been reported. Depending on review of two large data bases, we report this case series. In addition, we evaluated the posterior decompression as the management option in treatment of this rare condition. MATERIALS AND METHODS: Data of all cases with cervical spondylosis and canal stenosis that sought medical advice or needed decompressive laminectomy/laminoplasty between the years 2006 and 2015 were checked in manually...

In the last ten years, there has been an exponential increase in endoscopic spinal surgery practice.With improvements in equipment quality and the availability of high definition camera systems, cervical endoscopic disc resection is now a viable alternative to anterior cervical decompression and fusion (ACDF) or disc arthroplasty for the treatment of disc prolapse and low grade stenosis.Based on the current literature, there is now strong evidence to support the use of transforaminal endoscopic approaches for the treatment of thoracic disc prolapse...

BACKGROUND: Patients with severe cervical multilevel stenosis and an adequate lordotic curvature often undergo multilevel laminectomies with posterior instrumented fusions. Although the "gold standard" for the fusion mass remains iliac crest autograft, many require additional volume provided by bone graft expanders. Here, we studied the fusion rates for 32 patients undergoing multilevel cervical laminectomy and vertex/rod/eyelet/titanium cable fusions utilizing lamina/iliac autograft and the bone graft expander Nanoss (RTI Surgical, Alachua, FL, USA) with autogenous bone marrow aspirate (BMA)...

The risk for spinal cord injuries (SCIs) ranging from devastating traumatic injuries, compression due to degenerative pathology, and neurapraxia is increased in patients with congenital spinal stenosis. Classical diagnostic criteria include an absolute anteroposterior diameter of <12-13mm or a Torg-Pavlov Ratio of <0.80-0.82; however, these factors do not take into account the size of the spinal cord, which varies across patients independent of canal size. Recent large MRI studies of population cohorts have allowed newer methods to emerge that account for both cord and canal size by measuring a spinal cord occupation ratio (SCOR)...

OBJECTIVES/HYPOTHESIS: Despite surgical advances, childhood tracheal stenosis is associated with high morbidity and mortality. Various tracheal scaffold strategies have been developed as the basis for bioengineered substitutes, but there is no consensus on which may be superior in vivo. We hypothesized that there would be no difference in morbidity and mortality between three competing scaffold strategies in rabbits. STUDY DESIGN: Pilot preclinical study. METHODS: Tracheal scaffolds were prepared by three methods that have been applied clinically and reported: preserved cadaveric ("Herberhold") allografts, detergent-enzymatically decellularized allografts, and synthetic scaffolds (nanocomposite polymer [polyhedral oligomeric silsesquioxane poly(carbonate-urea) urethane (POSS-PCU)])...
