BACKGROUND: Previous studies have reported a high incidence of re-collapse of the augmented vertebrae after percutaneous vertebral augmentation (PVA) for osteoporotic vertebral compression fractures (OVCFs) with intravertebral vacuum cleft (IVC) during long-term follow-up. Previous IVC might be considered an important predisposing factor for re-collapse, but the prior studies could not find a significant correlation. OBJECTIVE: To determine the incidence and distribution characteristics of IVCs and to further assess IVCs in their varied locations...

BACKGROUND: Bertolotti's syndrome is a spinal disorder characterized by abnormal enlargement of the transverse process of the most caudal lumbar vertebra. The L5 transverse process may be enlarged either unilaterally or bilaterally and may articulate or fuse with the sacrum or ilium. Pseudoarticulation between the transverse process of the L5 and the alar of the sacrum can cause buttock pain and leg pain. In addition, the L4 exiting nerve root could be compressed by an enlarged L5 transverse process...

BACKGROUND/AIMS: Anastomotic leakage remains the most serious complications of colorectal surgery. To prevent colorectal anastomotic leakage (CAL), an air leak test (ALT) with intraoperative colonoscopy (IOCS) is performed to detect mechanically insufficient colorectal anastomoses. The approaches to an intraoperative anastomotic air leak (IOAL) have not been fully investigated. This study aimed to clarify the safe management of an IOAL in laparoscopic colorectal surgery. METHODS: One hundred forty-eight consecutive patients who underwent laparoscopic resection with double-stapling technique (DST) anastomosis for left-sided colorectal cancer between April 2015 and June 2016 were included and retrospectively reviewed...

The predictability of early postoperative ultrasonography (USG) for evaluating the structural integrity of repaired rotator cuffs is still unclear. The aim of this study was to compare the predictability of early USG performed 3 and 6 months postoperatively with magnetic resonance imaging (MRI) performed 1 year after arthroscopic cuff repair for structural failure. Among 213 patients who had arthroscopic rotator cuff surgery in 2013, one hundred thirty-eight patients who underwent USG between 3 and 6 months postoperatively and MRI at 1 year postoperatively were enrolled; the postoperative MRI findings were the reference standard used for the comparison...

Postoperative radiographs remain the standard for assessment of component placement following total hip arthroplasty (THA), despite the known limitations of radiographs. Computed tomography (CT) scanning offers improved accuracy, but its costs and radiation exposure are prohibitive. The authors performed a cadaver study to compare the error associated with radiographs with that of CT scans following THA. The authors also compared imaging with a novel mini-navigation system. Three board-certified orthopedic surgeons each performed 4 THA procedures (6 cadavers, 12 hips) via the posterior approach using a mini-navigation tool to assist with component placement...

Sleep and pain are reciprocally related, but the precise mechanisms underlying this relationship are poorly understood. This study used a rat model of surgical pain to examine the effect of previous sleep loss on postoperative pain and tested the hypothesis that preoptic adenosinergic mechanisms regulate sleep-pain interactions. Relative to ad libitum sleep, 6 hours of total sleep deprivation prior to a surgical incision significantly enhanced postoperative mechanical hypersensitivity in the affected paw and prolonged the time to recovery from surgery...

BACKGROUND: Perioperative fluid strategies influence clinical outcomes following major surgery. Many intravenous fluid preparations are based on simple solutions, such as normal saline, that feature an electrolyte composition that differs from that of physiological plasma. Buffered fluids have a theoretical advantage of containing a substrate that acts to maintain the body's acid-base status - typically a bicarbonate or a bicarbonate precursor such as maleate, gluconate, lactate, or acetate...

REVIEW
Stefan Heinrich, Hauke Lang
The standard treatment of resectable pancreatic cancer is surgery followed by adjuvant chemotherapy. Due to the complication rate of pancreatic surgery and the high rate of primary irresectability, neoadjuvant concepts are increasingly used for pancreatic cancer. Neoadjuvant therapy is better tolerated than adjuvant and might decrease the surgical complication rate from pancreatic surgery. In contrast to neoadjuvant chemoradiation, the nutritional status improves during neoadjuvant chemotherapy. Also, the survival of patients who develop postoperative complications after neoadjuvant therapy is comparable to those without complications whereas the survival of patients who underwent upfront surgery and then develop surgical complications is impaired...

PURPOSE OF THE STUDY Anxiety may have negative repercussions on the surgery including poorer outcomes. On the other hand, the majority of patients reporting preoperative anxiety fear not receiving enough attention from a caregiver. In patients undergoing fast-track knee arthroplasty, we determined the relationship between patients' preoperative anxiety and the anxiety the patient's caregiver. We also analyzed the influence of selected psychosocial and demographic variables on the relationship between caregivers' and patients' anxiety...
