Background and Aim: Laparoscopic and open rectum surgery for rectal cancer remains controversial. This systematic review compared the short-term and long-term efficiency and complications associated with laparoscopic and open resection for rectal cancer. Materials and Methods: We searched PubMed, Embase, Cochrane Library, ISI Web of Knowledge and the China Biology Medicine Database to identify potential randomized controlled trials from their inception to March 31, 2014 without language restriction. Additional articles were identified from searching bibliographies of retrieved articles. Two reviewers independently assessed the full-text articles according to the pre-specified inclusion and exclusion criteria as well as the methodological quality of included trials. The meta-analysis was performed using RevMan 5.2. Results: A total of 16 randomized controlled trials involving 3,045 participants (laparoscopic group, 1,804 cases; open group, 1,241 cases) were reviewed. Laparoscopic surgery was associated with significantly lower intraoperative blood loss, earlier return of bowel movement and reduced length of hospital stay as compared to open surgery, although with increased operative time. It also showed an obvious advantage for minimizing late complications of adhesion-related bowel obstruction. Importantly, there were no significant differences in other postoperative complications, oncological clearance, 3-year and 5-year or 10 year recurrence and survival rates between two procedures. Conclusions: On the basis of this meta-analysis we conclude that laparoscopic surgery has advantages of earlier postoperative recovery, less blood loss and lower rates of adhesion-related bowel obstruction. In addition, oncological outcome is comparable after laparoscopic and open resection for rectal cancer.

Objective : Stroke is the most prevalent disease involving the central nervous system. Since medical modalities are sometimes ineffective for the acute edema following massive infarction, surgical decompression may be an effective option when medical treatments fail. The present study was undertaken to assess the outcome and prognostic factors of decompressive surgery in life threatening acute, severe, brain infarction. Methods : We retrospectively analyzed twenty-six patients (17 males and 9 females; average age, 49.7yrs) who underwent decompressive surgery for severe cerebral or cerebellar infarction from January 2003 to December 2006. Surgical indication was based on the clinical signs such as neurological deterioration, pupillary reflex, and radiological findings. Clinical outcome was assessed by Glasgow Outcome Scale (GOS). Results : Of the 26 patients, 5 (19.2%) showed good recovery, 5 (19.2%) showed moderate disability, 2 (7.7%) severe disability, 6 (23.1%) persistent experienced vegetative state, and 8 (30.8%) death. In this study, the surgical decompression improved outcome for cerebellar infarction, but decompressive surgery did not show a good result for MCA infarction (30.8% overall mortality vs 100% mortality). The dominant-hemisphere infarcts showed worse prognosis, compared with nondominant-hemisphere infarcts (54.5% vs 70%). Poor prognostic factors were diabetes mellitus, dominant-hemisphere infarcts and low preoperative Glasgow Coma Scale (GCS) score. Conclusion : The patients who exhibit clinical deterioration despite aggressive medical management following severe cerebral infarction should be considered for decompressive surgery. For better outcome, prompt surgical treatment is mandatory. We recommend that patients with severe cerebral infarction should be referred to neurosurgical department primarily in emergency setting or as early as possible for such prompt surgical treatment.

Intracranial hemorrhage due to preeclampsia in the postpartum woman is rarely documented. Generally, the incidence of stroke is increased during pregnancy and early postpartum. Preeclampsia is considered a main cause of both nonhemorrhagic and hemorrhagic stroke. We present a 32-year-old woman who had intracranial hemorrhage at 5 days postpartum. At admission, her consciousness was semicomatose with elevated blood pressure. Computerized tomography revealed intracranial hemorrhage on right frontal lobe. Additional angiography did not reveal abnormal vascular lesion. Emergency craniectomy with hematoma removal was done. However, the patient showed no recovery and died 2 weeks later. We conclude that postpartum care of preeclampsia is important to prevent intraparenchymal hemorrhage. Relative high risk of stroke during the postpartum period suggests a causal roles for the large decrease in blood volume or the rapid changes in hormonal status that follow a live birth or stillbirth, perhaps by means of hemodynamics, coagulative, or vessel wall changes.

Objective : Many authors suggest that patients with traumatic subarachnoid hemorrhage(tSAH) visible on first CT after heve injury had a significantly worse prognosis than patients who do not. The aim of this study is to identify patients with tSAH who present with a bad prognosis by reviewing their clinicoradiological features and plan appropriate treatments. Patients and Methods : We reviewed and analysed the factors that influenced discharge outcomes in 172 patients with tSAH for a 3-year period. The outcome was divided into good(good recovery and moderate disability of glasgow outcome scale) and good(severe disability, vegetative state and death). Results : A regression analysis of statistical significant factors(p<0.05) among the clinical and CT features ranked them by descending order of contribution to Glasgow Outcome Scale(GOS) scores at the time of discharge from acute hospitalization as follows 1) clinical : admission Glasgow Coma Scale(GCS), hypotension, CT grade, abnormal APTT, skull fracture, hyperglycemia(>160mg/dl), hypoxia, operation, 2) CT : basal cistern effacement(BCE), mass lesion, cortical sulcal effacement(CSE), midline shift. Conclusion : We have also experienced that the CT grading scale proposed by Green et al is a simple and useful prognostic factor. The authors believe that the patients with high CT grade need adjuvant therapies as of well surgery but it seems mandatory to consider early identification and correction of hypotension, hyperglycemia, and hypoxia in emergency setting.

The Internet marketing of hospital is being considered as a strategic requirement that can satisfy the customers. Therefore, it is very important to understand the effects of the medical information on the Internet on the actual consumers. In this study, the paths through which the attitude and satisfaction of the medical information consumers that visit hospital web site are formed for the medical information through the quality of the medical information on the Internet and usability of hospital web site were examined respectively according to the medical examination and treatment subjects that respectively deal with medical acts and cosmetic acts through light metabolism recovery. The usability of hospital web site, rather than medical information quality, had positive effects on the attitudes toward the medical information distributed in the corresponding web site and the satisfaction of use of hospital web site in the case of visitors of the hospital web site for the medical examination and treatment subjects of essential medical examination and treatment and emergency medical treatment, and, on the other hand, the result of analyzing the path of the medical examination and treatment subjects of cosmetics and functional improvement revealed that the medical information quality had positive effects on the medical information attitudes and the usage satisfaction of hospital web site. Accordingly, the attitudes toward the medical information distributed through the web site by the visitors of hospital web site is formed from the quality of medical information and web site usability, and, ultimately, they become generally satisfied with the hospital web site. Such process is revealed different1y according to the medical examination and treatment subjects for which consumers desire to obtain information.

Intussusception in adult is a rare disease and laparotomy is usually considered because of the probability of malignancy. Especially with obstruction symptom or sign, it might be needed emergency operation. This case was a simultaneous development of small bowel intussusception and acute hepatitis A. The patient had abdominal pain and vomiting. Intitial laboratory examination with elevated aminotransferase revealed that the diagnosis was acute hepatitis. As managing acute hepatitis, the abdominal pain was not improved and the patient had tenderness on periumbilical area on physical examination. A jejunal intussusception with a lead point was proved on the abdominal computed tomography scan. Fortunately, symptom of intussusception was relieved while nulli per os (NPO) and intravenous hydration. After recovery of acute hepatitis, laparotomy was done. The lead point was $2.5{\times}3.0cm$ sized hamartoma. This was the case that the symptom of intussusception was confused with that of acute hepatitis.

An increase in oil and gas plants caused by development of process industry have brought into the increase in use of flammable and toxic materials in the complex process under high temperature and pressure. There is always possibility of fire and explosion of dangerous chemicals, which exist as raw materials, intermediates, and finished goods whether used or stored in the industrial plants. Since there is the need of efforts on disaster damage reduction or mitigation process, we have been conducting a research to relate explosion model on the background of real 3D terrain model. By predicting the extent of damage caused by recent disasters, we will be able to improve efficiency of recovery and, sure, to take preventive measure and emergency counterplan in response to unprepared disaster. For disaster damage prediction, it is general to conduct quantitative risk assessment, using engineering model for environmental description of the target area. There are different engineering models, according to type of disaster, to be used for industry disaster such as UVCE (Unconfined Vapour Cloud Explosion), BLEVE (Boiling Liquid Evaporation Vapour Explosion), Fireball and so on, among them, we estimate explosion damage through UVCE model which is used in the event of explosion of high frequency and severe damage. When flammable gas in a tank is released to the air, firing it brings about explosion, then we can assess the effect of explosion. As 3D terrain information data is utilized to predict and estimate the extent of damage for each human and material. 3D terrain data with synthetic environment (SEDRIS) gives us more accurate damage prediction for industrial disaster and this research will show appropriate prediction results.

Purpose: Varicella-zoster virus (VZV) infection is a common childhood disease. However, old and immune compromised patients are also at risk. Necrotizing fasciitis is a life threatening infection of the subcutaneous tissues, rapidly extending along the fascial planes. It is associated with a significant mortality rate, reported between 20% and 50%, and is therefore regarded as a surgical emergency. The authors treated a patient, who developed skin necrosis of her nose and left hemifacial area, following VZV infection. There are few literatures concerning this case; therefore, we present a rare case with review of literature. Methods: A 39-year-old woman had shown a localized, painful, multiple bullae and eschar formation in her nose and left hemifacial area for several days. Her skin lesion had rapidly worsened in size and morphology. Results: We diagnosed her as a necrotizing fasciitis, following herpes zoster, and then we performed a debridement of necrotic tissue and took a full thickness skin graft on her nose and left hemifacial area. Now, she was followed up with acceptable aesthetic result after 6 months. Conclusion: Secondary bacterial skin infection following VZV, can cause a result in a higher risk of complications. Among the complication, a necrotizing fasciitis of the head and neck is uncommon, and involvement of the nose is even more rare. Through this uncommon case report, we intend to emphasize the fact that early diagnosis of necrotizing fasciitis is very important, since it frequently necessitates surgical treatment which improves morbidity and leads to good recovery.

Background: The purpose of this retrospective study was to investigate the usefulness of tracheostomy scoring system in the decision of postoperative airway management in oral cancer patients. Materials and methods: A total of 104 patients were reviewed in this retrospective study, who underwent radical resection with or without neck dissection and free flap reconstruction due to oral cancer. The patients were classified into three groups according to the timing of the extubation; extubated groups (n = 51), overnight intubation group (n = 45), and tracheostomy group (n = 8). Cameron's score was used to evaluate the relation between the state of the patient's airway and the type of the operation. Results: Tracheostomy was performed in eight patients (8/104, 7.7 %). A total of 22 patients (21.2 %) had more than 5 points of which 17 patients (77.3 %) did not have a tracheostomy and any postoperative emergency airway problems. The tracheostomy scores were significantly different among the three groups. Hospital stay showed a significant correlation with the tracheostomy score. Conclusions: The scoring system did not quite agree with the airway management of the authors' clinic; however, it can be one of the clinical factors predicting the degree of the postoperative airway obstruction and surgical aggressiveness for recovery. The further studies are needed for clinically more reliable scoring systems.
