REVIEW
Shilpa Jain, Sadhna Dhingra
Esophageal cancer is a serious malignancy with high mortality. The two common distinctive pathologic subtypes of esophageal cancer are squamous cell carcinoma and adenocarcinoma. These differ with regards to etiology, ethnic distribution, pathogenesis, and location in the esophagus. The precursor lesions are also unique to each subtype. Squamous cell carcinoma is more common in East Asia, is linked to smoking and tobacco use, more commonly involves the middle esophagus, and the precursor lesion is squamous dysplasia...

BACKGROUND: Surgical interventions such as posterior lumbar interbody fusion (PLIF) with and without posterior instrumentation are often employed in patients with degenerative spinal conditions that fail to respond to conservative medical management. The VariLift(®) Interbody Fusion System was developed as a stand-alone solution to provide the benefits of an intervertebral fusion device without the requirement of supplemental pedicle screw fixation. METHODS: In this retrospective case series, 25 patients underwent PLIF with a stand-alone VariLift(®) expandable interbody fusion device without adjunctive pedicle screw fixation...

OBJECTIVE: While a significant amount of experience has accumulated for awake procedures for brain tumor, epilepsy and carotid surgery, its utility for intracranial neurovascular indications remains largely undefined. Awake surgery, for select neurovascular cases, offers the advantage of precise brain mapping and robust neurological monitoring during surgery for lesions in eloquent areas, avoidance of potential hemodynamic instability, and possible faster recovery. Additionally, it opens the window for perilesional epileptogenic tissue resection with potentially less risk for iatrogenic injury...

BACKGROUND AND AIMS: Patients with Crohn's disease (CD) are often prescribed opioids chronically to manage pain associated with their disease. However, little evidence exists to support this practice. Here, we examine newly diagnosed patients with CD with and without chronic opioid use (COU) and sought to identify predictors and consequences of COU. METHODS: A nationally representative administrative health care claims that data set identified newly diagnosed patients with CD...

BACKGROUND: Successful endoscopic endonasal surgery for the resection of skull base tumors is reliant on preoperative imaging to delineate pathology from the surrounding anatomy. The increased signal-to-noise ratio afforded by 7T MRI can be used to increase spatial and contrast resolution, which may lend itself to improved imaging of skull base. In this study, we apply a 7T imaging protocol to patients with skull base tumors and compare the images to clinical standard of care. METHODS: Images were acquired at 7T on 11 patients with skull base lesions...

BACKGROUND: Around 10-15% of patients with gastroesophageal reflux disease will develop Barrett's esophagus (BE). The development of novel endoscopic modalities has changed the management of BE in the last decade. AIM: The aim of this study was to review the current evidence for the treatment of BE with and without dysplasia. RESULTS: In patients with BE without dysplasia, antireflux surgery should not be suggested as a modality to prevent the malignant transformation of BE, but its indications should be the same as for other patients with gastroesophageal reflux...

PURPOSE OF REVIEW: Cervical disc replacement (CDR) has emerged as a motion-preserving alternative to anterior cervical discectomy and fusion in selected cases. Despite favorable literature, CDR is not universally accepted because of concerns regarding bias in the existing literature. The purpose of this review is to identify the possible biases in the disc replacement literature. RECENT FINDINGS: Recent studies that compare CDR and ACDF have demonstrated equivalent or superior outcomes, lower rates of secondary surgery, and equivalent safety at medium- and long-term follow-up...

BACKGROUND: Bilateral pelvic discontinuity is characterized by complete dissociation of the superior and inferior pelvis secondary to bone loss or fracture. The end result is a freely mobile inferior pelvis at the level of each discontinuity which presents a significant reconstruction challenge. This clinical entity has not been described previously, and the results of surgical treatment are not known. METHODS: We retrospectively reviewed all identified cases of pelvic discontinuity (PD) treated with revision THA at one institution...

Obesity has reached epidemic proportions worldwide and is associated with a higher mortality from several diseases, including adenocarcinoma of the esophagus and of the gastric cardia. Increased body mass index is associated with an increased incidence of gastroesophageal reflux disease (GERD), Barrett metaplasia, and adenocarcinoma of the cardia. Bariatric surgery remains the most effective therapy for morbid obesity and has the potential to improve weight-related GERD. A high index of suspicion is paramount for early detection of foregut neoplasia after bariatric surgery...
