Pancreatic cancer is the fourth leading cause of cancer-related death. Early detection is challenging because symptoms are relatively nonspecific. Imaging is vital in detecting and staging pancreatic tumors, and management depends on imaging findings. Radiologists should be aware of current surgical treatments for pancreatic neoplasms, as surgeons rely on interpretation of cross-sectional imaging for presurgical planning. Understanding postsurgical anatomy is critical to assess for complications and recurrence...

OBJECTIVE: Distal branches of the C1 nerve that travel with the hypoglossal nerve have been well investigated but relationships of C1 and the hypoglossal nerve near the skull base have not been described in detail. Therefore, the aim of this study was to investigate these small branches of the hypoglossal and first cervical nerves by anatomical dissection. METHODS: Twelve sides from six cadaveric specimens were used in this study. To elucidate the relationship among the hypoglossal, vagus, and first and cervical nerve, the mandible was removed and these nerves were dissected under the surgical microscope...

OBJECTIVE: A significant proportion of children with congenital hearing loss who are candidates for cochlear implants (CIs) may have inner ear malformations (IEMs). Surgical and speech outcomes following CI in these children have not been widely reported. METHODS: The charts of children who were evaluated for a CI between 1/1/1986 and 12/31/2014 at a university-based tertiary level pediatric cochlear implant center were reviewed. Principal inclusion criteria included (i) age 1-18 years, (ii) history of bilateral severe to profound sensorineural hearing loss, and (iii) limited benefit from binaural amplification...

BACKGROUND: With improving surgical techniques for total elbow arthroplasty clinical outcomes have improved and its utilization continues to increase. Despite these advances, complication rates remain as high as 24%. Of these complications periprosthetic joint infection is one of the most common and morbid. The rheumatoid elbow remains a leading indication for total elbow arthroplasty. Patients with this condition frequently require immunosuppressive therapy, which places them at higher risk of both typical and atypical infections...

Decreased coaptation height in adults has been identified as a marker of early valve failure. We evaluated aortic valve coaptation and effective height in healthy children and in children with a ventricular septal defect (VSD) with aortic cusp prolapse (ACP), using echocardiography. We included 45 subjects with VSD with ACP, 27 did not develop aortic regurgitation (AR) by ACP and 18 developed AR by ACP, and 83 healthy children as controls. Aortic root anatomy was estimated using the parasternal long-axis view...

BACKGROUND CONTEXT: Whilst most cadaveric studies of the RLN have focused on course variations, they have usually been done on preserved (fixed and embalmed) cadavers which renders the RLN immobile and of less surgical landmark value. PURPOSE: Our aim was to perform a thorough exposure in fresh cadavers with the intention of investigating inferior thyroid artery and Berry's ligament as reliable landmarks for the identification of the RLN in anterior cervical spine surgery...

OBJECTIVE: The popularity of the superficial circumflex iliac artery perforator (SCIP) flap has been limited by factors such as variable vascular anatomy and short arterial pedicle. This article aimed to delineate flap design and harvest strategies based around either the proximal or distal perforators of the superficial circumflex iliac artery (SCIA) and propose a set of strategies that can help deal with the limitations of the flap. METHOD: From August 2011 to June 2015, the SCIP flap was used in 80 patients for soft tissue defects at our institution...

Total anomalous pulmonary venous connection (TAPVC) is predominantly a neonatal congenital cardiac diagnosis in which the pulmonary veins fail to return to the left atrium. The presence or absence of obstruction defines the clinical presentation, and in the setting of obstructed pulmonary veins, this diagnosis represents a true surgical emergency. Improvements in perioperative care and refinement of surgical techniques continue to allow for improved survival and decreased morbidity. A description of the surgical anatomy and key concepts in the perioperative and surgical management of TAPVC are presented in this review...

Background and aims Precut papillotomy is widely used after failed biliary cannulation. Endoscopic ultrasound (EUS)-guided biliary access techniques are newer methods to facilitate access and therapy in failed cannulation. We evaluated the impact of EUS-guided biliary access on endoscopic retrograde cholangiopancreatography (ERCP) success and compared these techniques to precut papillotomy. Patients and methods We retrospectively compared two ERCP cohorts. One cohort consisted of biliary ERCPs (n = 1053) attempted in patients with native papillae and surgically unaltered anatomy in whom precut papillotomy and/or EUS-guided biliary access were routinely performed immediately after failed cannulation...

Septal reduction therapy (SRT) is the accepted therapeutic option for symptomatic hypertrophic obstructive cardiomyopathy (HOCM). At this time, surgical septal myectomy is the gold standard method, but alcohol septal ablation is an acceptable alternative treatment for patients with suitable anatomy. Endocardial septal ablation (ESA) therapy is a little-known method of SRT. Presently described is case of successful ESA procedure performed for HOCM.

BACKGROUND: Patients with resorbed edentulous alveolar ridges in the posterior maxilla often require lateral window sinus augmentation procedures prior to implant placement. Lateral window sinus augmentation procedures can produce incomplete bone augmentation as consequence of surgical and healing complications producing unusual and complex sinus anatomy. Although incomplete bone formation after sinus augmentation has been described in a previous case reports, this is the first case report that describes grafting these compromised sites prior to implant placement...

Disruption of the thoracic duct can have devastating consequences and be associated with a high morbidity and mortality. Conservative therapies have been attempted to treat chylothorax without much success. Surgical management has traditionally been necessary to provide definitive treatment at the expense of increased morbidity. Lymphatic interventions have recently emerged as a new frontier for interventional radiologists to add value and provide minimally invasive therapies for debilitating conditions. The goal of this manuscript is to review the anatomy of the thoracic duct, describe various percutaneous techniques for accessing the duct, and briefly discuss outcomes as reported in the literature...

BACKGROUND: Passive transcutaneous osseointegrated hearing implant systems have become increasingly popular more recently. The area over the implant is vulnerable due to vibration and pressure from the externally worn sound processor. Good perfusion and neural integrity has the potential to reduce complications. The authors' objective was to determine the ideal surgical exposure to maintain perfusion and neural integrity and decrease surgical time as a result of reduced bleeding. METHODS: The vascular anatomy of the temporal-parietal soft tissue was examined in a total of 50 subjects...

Deoxycholic acid (KybellaTM, Allergan Pharmaceuticals, Irvine, CA) is a novel injectable treatment used for the cosmetic reduction of redundant submental fat. By inducing adipose cell lysis, the soft tissue alteration induces subsequent contour change and sharpening of the cervicomental angle.The safety and efficacy have been well established in several prospective clinical trials and subsequent FDA approval for this purpose. This has provided an effective and less invasive alternative to surgical liposuction with virtually no recovery time and less overall discomfort...

BACKGROUND: Women with a septate uterus are at increased risk for subfertility, recurrent miscarriage, and preterm birth. Restoration of the anatomy of the uterus by hysteroscopic septum resection is an established intervention. This treatment has been assessed mainly in retrospective cohort studies, which suggested a positive effect on pregnancy outcomes. The major flaw in these studies is the before/after design, which will always favour the tested intervention. OBJECTIVES: To determine whether hysteroscopic septum resection in women of reproductive age with a septate uterus improves live birth rates and to assess the safety of this procedure...

INTRO: Common duct stones can be diagnosed by magnetic resonance cholangiopancreatography (MRCP), endoscopic ultrasound/endoscopic retrograde cholangiopancreatography (EUS/ERCP), and intra-operative cholangiogram (IOC). In 2015, our group adopted a standard approach of preoperative EUS/ERCP followed by laparoscopic cholecystectomy for patients with an admission bilirubin over 4.0 (mg/dL). For bilirubin less than 4.0, laparoscopic cholecystectomy with IOC was the initial procedure. Post-operative EUS/ERCP with endoscopic sphincterotomy was pursued for positive IOC...

Neuropathic symptoms after median nerve repair at the wrist or secondary to refractory carpal tunnel syndrome may become debilitating. These symptoms develop due to perineural adhesions, intraneural fibrosis and fixation of the nerve to the transverse carpal ligament after surgery and often require neurolysis. Interposition of vascularized soft tissue over the median nerve at the time of neurolysis prevents recurrence of such adhesions. The synovial flap, fashioned from the synovial lining of the flexor tendon sheath, is an ideal tissue for this purpose...
