Surgery precedes both radiotherapy and chemotherapy as the first-line therapy for glioma. However, despite multimodal treatment, most glioma patients die from local recurrence in the resection margin. Glioma surgery is inherently lesional, and the response of brain tissue to surgery includes hemostasis, angiogenesis, reactive gliosis and inflammation. Unfortunately, these processes are also associated with tumorigenic side-effects. An increasing amount of evidence indicates that the response to a surgery-related brain injury is hijacked by residual glioma cells and participates in the local regeneration of tumor tissues at the resection margin...

The incidence of vertebral artery (VA) injury (VAI) in posterior approach tumor resection surgery is extremely rare, but it can lead to serious complication. In this case, a 57-year-old man underwent surgery for resection of the tumor involving left epidural space and neural foramen at C2-3 level. Iatrogenic VAI occurred suddenly during tumor resection procedure using pituitary forceps. Immediate local hemostasis and maintaining of perfusion for reducing the risk of posterior circulation ischemia were performed...

The most common initial strategy for treatment of severe liver trauma is damage control in which hemostasis is achieved by perihepatic gauze packing and/or vascular embolization. However, we encounter patients in whom this strategy alone is not adequate. We have applied the principles of Glissonean pedicle transection, a technique that was originally devised to ensure safe and quick performance of planned hepatectomy for liver cancer, to 3 cases of severe liver trauma. We performed Glissonean pedicle ligation during damage control surgery in 2 patients and Glissonean pedicle transection during the definitive surgery in 1 patient...

When patients on antiplatelet therapy (APT) require minor invasive surgery, APT is usually continued to limit the risk of thrombosis. However, the possibility of hemostatic difficulties necessitates the monitoring of platelet aggregation to prevent unexpected bleeding. We examined whether whole blood aggregometry as a point-of-care testing (POCT) could be useful as a tool for predicting hemostatic difficulties. Sixty-five patients receiving APT and 15 patients who were not receiving APT were enrolled in the present study; all patients were scheduled to undergo a tooth extraction...

Helicobacter pylori (H. pylori) infection is one of the major causes of bleeding peptic ulcer disease, which is associated with serious complications; therefore, the eradication of H. pylori is essential to prevent these devastating complications. Post-treatment follow-up is crucial to guarantee the eradication of the organism and may be conducted via the urea breath test, the stool antigen test, or a gastric biopsy. Acute massive upper gastrointestinal (UGI) bleeding is one of the most common complications of peptic ulcer disease...

Multiloculated hydrocephalus (MLH) is a condition in which patients have multiple, separate abnormal cerebrospinal fluid collections with no communication between them. Despite technical advancements in pediatric neurosurgery, neurological outcomes are poor in these patients and the approach to this pathology remains problematic especially given individual anatomic complexity and cerebrospinal fluid (CSF) hydrodynamics. A uniform surgical strategy has not yet been developed. Current treatment options for MLH are microsurgical fenestration of separate compartments by open craniotomy or endoscopy, shunt surgery in which multiple catheters are placed in the compartments, and combinations of these modalities...

Oral anticoagulant therapy is frequently and increasingly prescribed for patients at risk of arterial or venous thromboembolism (VTE). Although elective surgical or invasive procedures have necessitated temporary interruption of anticoagulants, managing these patients has been performed empirically and been poorly investigated. This study was designed to evaluate the adequacy of perioperative anticoagulation using enoxaparin. This was a retrospective, single-center study that evaluated the efficacy and safety of therapeutic-dose enoxaparin for bridging therapy in patients on long-term warfarin at Soonchunhyang University Hospital in Korea between August 2009 and July 2011...

Uniportal video-assisted thoracic surgery (VATS) lung wedge resection usually requires three devices, thoracoscope, lung retracting instrument and an endo-stapler cutter to perform the procedure. With advances in miniaturization of the thoracoscope and lung retracting instruments, a major limitation to operating through a smaller uniportal incision has become the endo-stapler. We describe the surgical technique for uniportal VATS laser lung resection which uses a much narrower laser catheter device to replace the endo-stapler for resection...
