Healthcare accreditation, which in the Republic of Korea is based on Article 58 of the Medical Service Act of July 2010, is an evaluation system designed to improve the quality of medical services and secure patient safety. Although ambulatory health organizations such as clinics comprise the majority of all health facilities, because they are not currently evaluated, securing quality and patient safety nationwide is not possible under the existing system. This article reviewed the accreditation programs of ambulatory health organizations in leading countries such as the United States and Australia in order to propose a successful model for Korea. The Accreditation Association for Ambulatory Health Care of the Unites States is a private, non-profit organization established in 1979. Similarly, Australian General Practice Accreditation Limited is a non-profit organization established in 1997 to deliver services to support general practices in Australia. Both are independent professional organizations and perform accreditation programs by a self-regulatory system. As healthcare quality improvement and accreditation have the characteristics of professional service activities, a self-regulatory approach rather than a government-controlled one, and process-oriented evaluation rather than structure-focused evaluation, are known to be effective. We expect an accreditation program for clinics in Korea to be established using a self-regulatory approach by an independent professional organization, not by the government, in the near future.

Purpose: This study aims to investigate regional patterns and graft survival rates in kidney transplantation (KT) within South Korea using the National Health Insurance Service database. Methods: By analyzing KT data from 2002 to 2017, including patient residency, KT location, and post-KT dialysis information, graft survival was assessed through post-KT dialysis and validated against Ulsan University Hospital and the Korean Organ Transplantation Registry’s 2017 report. Results: Among the 20,978 KTs, 60.5% occurred in the Korean capital, Seoul, whereas 39.5% occurred outside. The overall graft survival rate was 81.5% with a median survival duration of 57 months. Patient survival was 83.8%, with a median survival duration of 61 months. For KTs from 2002 to 2007, the 10-year graft and patient survival rates were 89.1% and 90.3%, respectively. The KT recipients living outside Seoul who underwent the KT within their residential regions had a graft survival rate of 88.3%, and those receiving KTs outside their original region had a graft survival rate of 88.0%. Among Seoul residents who underwent KTs in the city, the graft survival rate was 90.5%. Importantly, hospital location did not significantly affect graft survival rates (P = 0.136). Conclusion This study revealed a regional preference for KT in South Korea, particularly in the capital city, likely because of nonresidents. Nevertheless, the graft and patient survival rates showed no significant regional disparities. These findings emphasize the necessity for equitable KT service access across regions in order to optimize patient outcomes.

A case of a 30-year-old man who was admitted following a penetrating neck injury is presented. A clinical examination and operative findings identified semi-comatose mentality, neck muscle laceration, and transection of the left common carotid and vertebral arteries and the internal jugular vein. During the operation, the carotid arteries were repaired by interposition grafting, and the internal jugular vein was ligated. The vertebral artery was managed by interventional embolization. Although the patient had some neurological deficit, he was discharged on postoperative Day 52. This surgical case prompted a discussion regarding neurological outcomes, and surgical and endovascular treatment following vascular neck injury.

Major peripheral arterial graft infection is a potentially devastating complication of vascular surgery, associated with significant mortality and high amputation rates. Autologous saphenous veins are considered optimal arterial conduits for lower extremity revascularization in infected fields, but they are often unavailable or unsuitable in these patients. This study describes two patients with major peripheral graft infection, but without available autologous veins, who underwent graft excision and cryopreserved cadaveric arterial allograft reconstruction. Although long-term graft durability is unclear because of gradual deterioration and degeneration, these findings suggest that cadaveric allografts may be good options for patients with major peripheral graft infection.

PURPOSE: To assess the technical feasibility of laparoscopic distal pancreatectomy (LDP) focusing on the development of postoperative complications including pancreatic fistula (POPF). METHODS: From March 2001 to April 2010, 57 patients underwent a distal pancreatectomy. The patients were divided into two groups, LDP group (L group, n=15) and open distal pancreatectomy group (O group, n=42). The clinicopathological characteristics, surgical variables and postoperative outcomes of these 2 groups were compared retrospectively. RESULTS: Patients with a malignancy constituted 7% of the L group and 31% of the O group (p=0.084). The tumor size was significantly larger in the O group (2.6 vs. 5.3 cm). The body mass index (BMI) was significantly higher in the L group (24.9 vs. 22.9 kg/m2). One case of a pancreas pseudocyst in the L group was converted to open surgery due to intraoperative bleeding. The L group showed significantly less intraoperative bleeding, earlier start of solid meals and shorter hospital stay. There was no significant difference in the incidence of postoperative complications and POPF between the 2 groups. POPF of ISGPF grade B developed in 0 and 2 patients in the L group and O group, respectively. One intestinal obstruction and 1 fluid collection that required intervention was encountered in the O group. One patient with adenocarcinoma who underwent LDP was alive 25 months after surgery without recurrence. CONCLUSION: LDP provides the advantages of minimal access surgery with a comparable rate of POPF to ODP. LDP is considered suitable for benign and borderline-malignant pancreatic lesions.

BACKGROUND: In recent years, introduction of novel immunosuppressive agents and its proper implementation for clinical practice have contributed to improving clinical outcomes of kidney transplantation (KT). Here, we report clinical outcomes of KTs and related risk factors. METHODS: From July 1998 to June 2016, 354 KTs (182 from living and 172 from deceased donors) have been performed at Ulsan University Hospital. We retrospectively reviewed the clinical characteristics and outcomes of KT recipients, then estimated graft and patient survival rate were estimated and analyzed risk factors using Cox-regression. RESULTS: The median follow-up period was 53 months (range; 3 to 220 months). The mean ages of recipients and donors were 45.0 years (SD, 12.5) and 44.7 years (SD, 13.6) years, respectively. During follow-up, 18 grafts were lost and 5- and 10-year death-censored graft survival was 96.7% and 91.5%, respectively. Biopsy-proven acute rejection (BPAR) occurred in 71 patients (55 cases of acute cellular rejection and 16 of antibody-mediated rejection). Cox-regression analysis showed that BPAR was a risk factor related to graft loss (hazard ratio [HR], 14.38; 95% confidence interval [CI], 3.79 to 54.53; P < 0.001). In addition, 15 patients died, and the 5- and 10-year patient survival was 97.2% and 91.9%, respectively. Age ≥60 years (HR, 6.03; 95% CI, 1.12 to 32.61; P=0.037) and diabetes (HR, 6.18; 95% CI, 1.35 to 28.22; P=0.019) were significantly related to patient survival. CONCLUSIONS: We experienced excellent clinical outcomes of KT in terms of graft failure and patient survival despite the relatively high proportion of deceased donors. Long-term and short-term clinical outcomes have improved in the last two decades.

PURPOSE: The aim of this study was to introduce the phenomenon that stenosis or occlusion occurs less frequently in the innominate artery than in the right subclavian and common carotid arteries, which are not first-order branches of the aorta, in Takayasu arteritis (TA). MATERIALS AND METHODS: We retrospectively reviewed the medical records and image findings of all patients who were diagnosed with TA from 2006 to 2014. Two vascular surgeons and two radiologists interpreted the images by disease character, location, and extent of occlusion based on computed tomography angiography, magnetic resonance angiography, or digital subtraction arteriography. We have also reviewed the literature on arterial involvement in TA. RESULTS: A total of 42 patients were diagnosed with TA. The mean age was 43.9 years, and 83.3% (35/42) of the patients were women. The left subclavian artery was the most common stenosis or occlusion site (17, 40.5%) among the aortic branches. The innominate artery was a less common site (3, 7.1%) than the right subclavian artery (4, 9.5%) and the right common carotid artery (9, 21.4%). All innominate artery cases were found after endovascular procedures of the right subclavian or common carotid arteries. CONCLUSION: The innominate artery might develop stenosis or occlusion less frequently than the right subclavian and common carotid arteries in Korean TA patients.

Purpose: The aim of this study was to investigate the relationship between the anatomical location of thrombi in the lower extremities and the development of pulmonary embolism (PE). Materials and Methods: We collected and analyzed the data of patients diagnosed with deep vein thrombosis (DVT) of the lower extremities between 2006 and 2015, and included those whose computed tomography (CT) data were available for PE identification. We evaluated the relationship between the laterality and the proximal/distal location of the thrombi in lower extremites and the location of PE. Results: CT images were available for 388/452 patients with DVT. After excluding 32 cases with bilateral involvement, 356 cases were included for analysis in this study. The ratio of DVT in the left:right leg was 232:124. PEs developed in 121 (52.2%) patients with left-sided DVT and in 78 (62.9%) with right-sided DVT (P=0.052). PEs in the main pulmonary arteries developed in 36 (15.5%) patients with left leg DVT and in 30 (24.2%) with right leg DVT (P=0.045). The most frequent site of thrombosis associated with the development of PE was the left iliac vein (59/199, 29.6%). According to the anatomical segment of the leg affected by DVT, patients with DVT in the right femoral vein (50/71, 70.4%; P=0.016) had the highest rate of occurrence of PE. Conclusion PE develops more frequently in patients with right-sided DVT than in those with left-sided DVT. Therefore, careful observation for the possible development of PE is recommended in cases with right-sided DVT of the lower extremity.

Although the standard treatment of abdominal aortic aneurysm has shifted from open surgery to endovascular repair, open surgery has remained the standard of care for complex aneurysms involving the visceral arteries and in patients unsuitable for endovascular aneurysm repair. Postoperative renal insufficiency may occur after open surgical repair of suprarenal abdominal aortic aneurysm. Methods of minimizing renal ischemic injury include aortic cross-clamping and renal reconstruction techniques. This report describes the use of renal autotransplantation for renal reconstruction during open surgical repair of a suprarenal abdominal aortic aneurysm. This technique was successful, suggesting its feasibility for open suprarenal abdominal aortic aneurysm repair, minimizing renal ischemic injury and optimizing postoperative renal function.
