  • Catheter ablation of atrial fibrillation (AF) is one of the most complex interventional electrophysiological procedures. The success of AF ablation is based in large part on freedom from AF recurrence based on electrocardiography (ECG) monitoring. Arrhythmia monitoring can be performed with the use of noncontinuous or continuous ECG monitoring tools. AF ablation is an invasive procedure that entails risks, most of which are present during the acute procedural period. However, complications can also occur in the weeks or months following ablation. Recognizing common symptoms after AF ablation and distinguishing those that require urgent evaluation and referral to an electrophysiologist is an important part of follow-up after AF ablation. This section reviews the complications associated with catheter ablation procedures performed to treat AF. The types and incidence of complications are presented, their mechanisms are explored, and the optimal approach to prevention and treatment is discussed. Finally, surgical and hybrid AF ablation technology and the indications for concomitant open or closed surgical ablation of AF, stand-alone and hybrid surgical ablation of AF are covered in this section.

  • Congenital aural atresia is an ear malformation evident at birth, involving various degrees of failed external ear canal development. A true external ear canal is desirable, as devices that replace the canal are inconvenient and expensive. Therefore, an optimal surgical technique is required. Here, we review useful preoperative and operative techniques. Surgical correction is often not the preferred treatment; the hearing outcome is no better than the outcomes afforded by bone-conduction devices, and surgery may be associated with recurrence or complications such as meatal stenosis. Preoperative evaluation and appropriate management are important. Several means of preventing meatal stenosis are discussed in this review.

  • Epilepsy is one of the most common chronic neurological disorder affecting 6-7 per 1000 worldwide. Nearly one-third of patients with newly diagnosed epilepsy continue to have recurrent seizures despite adequate trial of more than two anti-seizure drugs : drug-resistant epilepsy (DRE). Children with DRE often experience cognitive and psychosocial co-morbidities requiring more urgent and aggressive treatment than adults. Epilepsy surgery can result in seizure-freedom in approximately two-third of children with improvement in cognitive development and quality of life. Understanding fundamental differences in etiology, co-morbidity, and neural plasticity between children and adults is critical for appropriate selection of surgical candidates, appropriate presurgical evaluation and surgical approach, and improved overall outcome.

  • Purpose: Delayed, traumatic, intraparenchymal hemorrhage (DTIPH) is a well-known contributing factor to secondary brain damage that evokes severe brain edema and intracranial hypertension. Once it has occurred, it adversely affects the patient's outcome. The aim of this study was to evaluate the prognosis factors for DTIPH by comparing clinical, radiological and hematologic results between two groups of patients according to whether surgical treatment was given or not. Methods: The author investigated 26 patients who suffered DTIPH during the recent consecutive five-year period. The 26 patients were divided according to their having undergone either a decompressive craniectomy (n=20) or continuous conservative treatment (n=6). A retrospective investigation was done by reviewing their admission records and radiological findings. Results: This incidence of DTIPH was 6.6% among the total number of patients admitted with head injuries. The clinical outcome of DTIPH was favorable in 9 of the 26 patients (34.6%) whereas it was unfavorable in 17 patients (65.4%). The patients with coagulopathy had an unexceptionally high rate of mortality. Among the variables, whether the patient had undergone a decompressive craniectomy, the patient's preoperative clinical status, and the degree of midline shift had significant correlations with the ultimate outcome. Conclusion: In patients with DTIPH, proper evaluation of preoperative clinical grading and radiological findings can hamper deleterious secondary events because it can lead to a swift and proper decompressive craniectomy to reduce the intracranial pressure. Surgical decompression should be carefully selected, paying attention to the patient's accompanying injury and hematology results, especially thrombocytopenia, in order to improve the patient's neurologic outcomes.

  • Purpose: The purpose of the study was to evaluate how advanced practice nurses (APNs) recognized their work by analyzing nursing outcomes. The ultimate goal was to examine the utility of APNs by connecting their work to the outcomes. Methods: Cross-sectional survey was conducted to collect the data from 59 APNs in a tertiary hospital lovated in Seoul, Korea. The questionnaire with 84 outcome indicators for advanced practice nurses was used. Descriptive statistics were used to analyze the data. Results: Among 84 outcome indicators, 11 indicators were associated with the work of APNs. Majority of these findings were included in the categories of clinical results and satisfaction. Items identified to be associated with the work of APNs were different among oncology nursing area, surgical speciality area, emergency care area, and critical care area. Conclusion: The results of the study indicated that the works of APNs were relevant to education/counseling/training and interpersonal relationship with other health professionals. The results of the study could be helpful to delineate the work characteristics of APNs and increase the utility of APNs in Korea where roles of APNs are not yet clearly delineated in most clinical settings.

  • Purpose: The purpose of this study was to assess the treatment outcomes and prognosis of Lisfranc joint fracture and dislocation according to the mechanism of injury and treatment method. Materials and Methods: Twenty six patients with Lisfranc fracture-dislocation who had been treated surgically were included in this retrospective study. The patients were divided into two groups according to mechanism of injury: direct crushing injury (16 patients) and indirect rotational or compressive injury (10 patients). The patients were also divided into three groups according to the surgical methods. The parameters used were radiographic evaluation, patients' subjective satisfaction levels, length of hospital stay, and the American Orthopaedic Foot and Ankle Society (AOFAS) midfoot score. Statistical analysis was performed. Results: The mean postoperative AOFAS midfoot score was 78.7. The mean length of stay was 39.6 days. Statistically significant differences in subjective satisfaction, AOFAS midfoot score, and length of hospital stay were observed between the two groups (p<0.05). However, no significance differences were observed between the three groups who were divided according to the different surgical methods (p>0.05). Conclusion: Mechanism of trauma and the severity of soft-tissue injury were significant prognostic factors affecting the surgical outcomes of Lisfranc joint fracture and dislocation.

  • With the widespread use of the obstetrical ultrasound, identification of a fetal suprarenal mass becomes more common. Most of these masses prove to be congenital neuroblastomas (CNB) postnatally. However, the diagnosis is often confused with other benign lesions and the post-natal management remains controversial. The medical records of 13 patients that underwent primary surgical excision for an antenatally detected adrenal CNB, between January 1995 and April 2009, were reviewed retrospectively. The clinical, radiological, surgical, and pathological data on the suprarenal mass were collected. Staging evaluation was performed after histological confirmation of the CNB. Most of the CNBs were stage I (N=11), with 1 stage IV and 1 stage IV-S. Four patients (3 stage I and 1 stage IV-S) had N-myc gene amplification. The stage I patients were cured by surgery alone, and stage IV patients underwent 9 cycles of adjuvant chemotherapy and currently have no evidence of disease after 39 months of follow-up. The patient with stage IV-S is currently receiving chemotherapy. There were no post-operative complications. For early diagnosis and treatment, surgical excision should be considered as the primary therapy for an adrenal CNB detected before birth. The surgery can be safely performed during the neonatal period and provides a cure in most cases. Surgical diagnosis and treatment of CNB is recommended in neonatal period.

  • Objective : Lumbar spine stenosis (LSS) can result in symptomatic compression of the neural elements, requiring surgical treatment if conservative management fails. Minimally invasive surgery has come to be more commonly used for the treatment of LSS. The current study describes outcomes of bilateral microdecompression by unilateral or bilateral laminotomy (BML) for degenerative LSS after a minimum follow-up period of 3 years and investigates factors that result in a poor outcome. Methods : Twenty-one patients who were followed-up for at least 3 years were included in this study. For clinical evaluation, the Japanese Orthopedic Association (JOA) scoring system for low back pain was used. The modified grading system of Finneson and Cooper was used for outcome assessment. Radiographic evaluation was also performed for spondylolisthesis, sagittal rotation angle, and disc height. Results : Twenty-one patients (10 men, 11 women) aged 53-82 years ($64.1{\pm}8.9$ years) were followed-up for a minimum of 3 years (36-69 months). During follow-up, two patients underwent reoperation. Average preoperative JOA score and clinical symptoms, except persistent low back pain, improved significantly at the latest follow-up. There were no significant differences in radiological findings preoperatively and postoperatively. Thirteen patients (61.9%) had excellent to fair outcomes. Conclusion : BML resulted in a favorable and persistent outcome for patients with degenerative LSS without radiological instability over a mid-term follow-up period. Persistent low back pain unrelated to postoperative instability adversely affects mid-term outcomes.

  • Objective: Clostridium difficile Infection (CDI) is one of the common nosocomial infections. As elderly population increases, the proper treatment has been emphasized. We investigated the risk factors associated with CDI unimprovement in elderly patients. Furthermore, we performed drug use evaluation of old CDI patients and oldest-old CDI patients. Methods: It was a retrospective study using electronic medical record at Kangbuk Samsung Medical Center (KBSMC) from January 2016 to December 2017. Seventy three patients aged 65 years or older, diagnosed with CDI by Clostridium difficile Toxin B Gene [Xpert] were screened and they were assessed for risk factors regarding unimprovement status. We also evaluated drug use evaluation in old patients ($65{\leq}age$<80) and oldest-old patients ($80{\leq}age$) by assessing the use of initial therapy, severity, dose, route, treatment course, days of use, total days of use and treatment outcome of initial therapy. Results: Out of 73 patients aged over 65 years, four patients were excluded because they did not receive any treatment. There were 31 improved patients and 38 unimproved patients after initial therapy. We were able to find out patients with surgical comorbidity or endocrine comorbidity (especially, diabetes mellitus) had 2.885 more risk of becoming unimproved than those patients without surgical comorbidity or endocrine comorbidity. Drug use evaluation for CDI was generally fair, but vancomycin as initial therapy is more recommended than metronidazole. Conclusion: Although age, antibiotics exposure, use of antacids are all important risk factors for CDI, our result did not show statistical significance for these risk factors. However, the study is meaningful because the number of elderly population keeps increasing and recently updated guideline suggests the use of vancomycin as drug of choice for CDI.
