OBJECTIVE: The use of 3-dimensional (3D) printing in medicine has rapidly expanded in recent years as the technology has developed. The potential uses of 3D printing are manifold. This article provides a systematic review of the uses of 3D printing within surgical training and assessment. METHODS: A structured literature search of the major literature databases was performed in adherence to PRISMA guidelines. Articles that met predefined inclusion and exclusion criteria were appraised with respect to the key objectives of the review and sources of bias were analysed...

Perioperative hypertension is a phenomenon in which a surgical patient's blood pressure temporarily increases throughout the preoperative and postoperative periods and remains high until the patient's condition stabilizes. This phenomenon requires immediate treatment not only because it is observed in a majority of patients who are not diagnosed with high blood pressure, but also because occurs in patients with underlying essential hypertension who show a sharp increase in their blood pressure. The most common complication following facelift surgery is hematoma, and the most critical risk factor that causes hematoma is elevated systolic blood pressure...

BACKGROUND: Postoperative pain and opioid use are associated with postoperative delirium. We designed a single-center, randomized, placebo-controlled, parallel-arm, double-blinded trial to determine whether perioperative administration of gabapentin reduced postoperative delirium after noncardiac surgery. METHODS: Patients were randomly assigned to receive placebo (N = 347) or gabapentin 900 mg (N = 350) administered preoperatively and for the first 3 postoperative days...

INTRODUCTION: The reconstruction of the body shape after post-bariatric surgery or high-grade gynecomastia involves, besides skin tightening, the repositioning of anatomical, apparent landmarks. The surgeon usually defines these during the preoperative planning. In particular, the positions of the nipple-areola complexes (NAC) should contribute to the gender-appropriate appearance. While in the female breast numerous methods have been developed to determine the optimal position of the NACs, there are only a few, metric and often impractical algorithms for positioning the nipples and areoles in the male...

OBJECTIVES: To study the correlation between MRI apparent diffusion coefficient (ADC) and expression of Ki-67 in gastric cancers, and to investigate the application of ADC value in diagnosing the malignance of gastric cancer. METHODS: A retrospective cohort analysis was performed on 87 gastric cancer patients who received MRI examination and radical resection at Zhejiang Provincial Hospital of Traditional Chinese Medicine from November 2014 to August 2015. All the postoperative resected samples were confirmed as gastric cancer...

BACKGROUND: Reconstruction of malunited diaphyseal fractures of the forearm is one of the most difficult treatments due to its complicated structure. Widespread usage of Digital Imaging and Communications in Medicine (DICOM) data of 3-dimensional (3D) computed tomography (CT) and 3D printing can make estimating the true plane of the deformity easy. METHODS: A 21-year-old man with limited supination due to left forearm nonunion deformity initially treated by locking plate fixation was referred to our hospital...

PURPOSE: To assess the amide proton transfer-weighted (APTw) MRI features of isocitrate dehydrogenase (IDH)-wildtype and IDH-mutant grade II gliomas and to test the hypothesis that the APTw signal is a surrogate imaging marker for identifying IDH mutation status preoperatively. METHODS: Twenty-seven patients with pathologically confirmed low-grade glioma, who were previously scanned at 3T, were retrospectively analyzed. The Mann-Whitney test was used to evaluate relationships between APTw intensities for IDH-mutant and IDH-wildtype groups, and receiver operator characteristic (ROC) analysis was used to assess the diagnostic performance of APTw...

Intraoperative frozen section (FS) can be reduced during thyroid lobectomy according to the results of fine needle aspiration (FNA). We evaluated the role of intraoperative FS in thyroid nodules with different diagnostic categories of the Bethesda System for Reporting Thyroid Cytopathology by FNA. This retrospective study included 1,235 nodules collected via thyroidectomy with both preoperative FNA and intraoperative FS at the Second Affiliated Hospital of Zhejiang University School of Medicine, from January 2011 to January 2014...

BACKGROUND: Breast reduction techniques depend on the vascularity of the pedicle. Preserving vascularity of the nipple-areolar complex (NAC) is mandatory for reduction mammoplasties, as the NAC is the most important aesthetic and functional unit of the breast. The inferior pedicle technique is the most common method for breast reduction; however, pedicle length may increase after using this technique and cause problems related to NAC viability in gigantomastic and hypertrophic breasts...

Computer-aided surgery (CAS) is now nearly 30 years old. It has brought to surgery a variety of tools, techniques, and paradigm changes that have had an impact on how surgeries are planned, executed, and evaluated. In this review, we examine the predictive, preventive, and personalized medicine (PPPM) aspects of CAS. We present a brief history of CAS, summarize its the state of the art, and discuss current trends and future developments related to PPPM. Of the three Ps, we note that the most important impact of CAS is on Personalization, in all the steps of the surgical treatment: preoperative planning, intraoperative execution, and postoperative evaluation...

Prostate cancer is a heterogeneous disease whose therapies frequently have adverse effects. Informed patient counseling regarding likely clinical outcomes is therefore important. In this systematic review we aimed to identify all external validations of tools that are used to predict clinical outcomes in patients undergoing radical prostatectomy and evaluate which are optimum for clinical implementation. PubMed and EMBASE were searched from 2007 to 2016. Search terms related to the inclusion criteria were: prostate cancer, clinical outcomes, radical prostatectomy, and prognosis...

OBJECTIVES: To examine the feasibility, acceptability, and effects of a novel tablet-based application, Story-Telling Medicine (STM), in reducing children's preoperative anxiety. METHODS: Children (N = 100) aged 7 to 13 years who were undergoing outpatient surgery were recruited from a local children's hospital. This study comprised 3 waves: Waves 1 (n = 30) and 2 (n = 30) examined feasibility, and Wave 3 (n = 40) examined the acceptability of STM and compared its effect on preoperative anxiety to Usual Care (UC)...

ptic loosening, instability and infection are the major causes of TKA failure. For many years, nuclear medicine (NM) imaging was helpful to frame a painful total joint arthroplasty. The differentiation of septic from aseptic prosthetic loosening is critical. The latest AAOS guidelines to detect periprosthetic joint infection (PJI) restrict the role of NM scintigraphy. On the other hand, several studies suggest that NM imaging plays an important role in the evaluation of patients with painful prosthesis, but its specificity in differentiating aseptic loosening from infection is low...

BACKGROUND: Primary hyperparathyroidism (PHPT) is a common endocrine disorder usually due to hyperfunctioning parathyroid glands (HP). Surgical removal of HP is the main treatment in PHPT, particularly in symptomatic patients. The correct detection and localization of HP is challenging and crucial as it may guide surgical treatment in patients with PHPT. To date, different imaging methods have been used to detect and localize HP in patients with PHPT including radiology, nuclear medicine and hybrid techniques...

The case for radical pathway re-design before surgery is in part driven by healthcare system pressures which are in turn the result of continuously rising demand in the face of tightly constrained resources. Such circumstances tend to drive revolutionary, rather than incremental, change. The current approach to preoperative assessment, that typically occurs in the weeks leading up to surgery, but is all too often only a few days before surgery, results in a lost opportunity for perioperative physicians to improve patient care...
