Three hundred and fourty two patients with a fracture of tibial shaft were treated and managed in the Department of Orthopaedic Surgery, Soon Chun Hyang University Hospital from January 1981 to December 1985. In 147 cases, 62 cases had only tibial shaft fracture and 85 tibial and fibular shaft fracture. All of these were treated conservatively by manipulation and cast immibilization. We analyzed the initial fracture characteristics, the treatment employed, and the subsequent complications in fracture healing in a series of patients who had sustained a tibial shaft fracture with and without a fibular fracture. The results were as follows; 1. Duration of average bone healing was more slowly in the patients more than twenty years old who were treated for a tibial shaft fracture with and without a concomitant fibular fracture than in the patients less than twenty years old. 2. Duration of average bone healing was more slowly by one or two weeks in the the group of tibial shaft fracture without fibular fracture than in than in those with fibular fracture. 3. The frequency of delayed union, nonunion, varus malunion and pain in the ipsilateral ankle joint were more increased in the group of the tibial shaft fractures without fibular fracture in than those with fibular fracture. 4. The frequency of valgus malunion was more increased in the group of the tibial shaft fractures with fibular fracture than in those without fibular fracture.

Purpose: Breast cancer is the second most common malignancy in Korean women, and its incidence has increased rapidly. The purpose of this study was to evaluate the treatment outcomes of patients with breast cancer treated at a low volume center. Methods: We retrospectively analyzed 401 patients with stage I-III breast cancer at Chosun University Hospital from January 1998 to December 2013. We reviewed medical records including clinical information and pathologic reports. Results: We found 401 cases of newly diagnosed breast cancer, including 5 (1.2%) male breast cancer patients. According to histological features, there were 43 cases (ductal carcinoma in situ (DCIS): 35 cases [8.7%], lobular carcinoma in situ (LCIS): 8 cases [2.0%]) of non-invasive carcinoma, 350 cases (87.3%) of invasive carcinoma, 2 cases (0.5%) of Paget’s disease, 1 case (0.2%) of malignant phyllodes tumor, 3 cases (0.7%) of sarcoma, and 2 cases (0.5%) of other types. With respect to disease stage, 117 (29.2%) patients were in stage I, 176 (43.9%) in stage II, and 78 (19.4%) in stage III. The type of surgical approaches were breast-conserving surgery (153, 38.2%), modified radical mastectomy (243, 60.6%), wide excision (4, 1.0%), and others (1, 0.2%). Five-year disease-free survival rates were 100% (stage 0), 95.4% (stage I), 91.4% (stage IIa), 75% (stage IIb), 78% (stage IIIa), 50% (stage IIIb), and 59.2% (stage IIIc). Overall survival rates were 100% (stage 0), 96.2% (stage I), 94.3% (stage IIa), 85.4% (stage IIb), 84.8% (stage IIIa), 50% (stage IIIb), and 55.5% (stage IIIc). Conclusion Although the patients were treated at a low-volume center, their favorable survival outcomes are notable. Further multicenter (low-volume centers) research is warranted.

Laparoscopic liver resection has been widely accepted nowadays for selective cases of liver diseases. Laparoscopic left lateral sectionectomy and minor LLR are considered standard practice worldwide and cautious introduction of major laparoscopic liver resections like hemihepatectomies, central sectionectomy etc.. in institutions having experienced liver surgeons. Because of increasing young liver donor, laparoscopic donor hepatectomy is becoming popular, which gives better cosmetic outcomes. Many clinical trials compared laparoscopic liver resection safety, long term outcomes with open procedures. More recently, advances in laparoscopic instruments and techniques encouraged Korean surgeons to choose a laparoscopic procedure as one of the treatment options for benign or malignant diseases of liver.

Kasabach-Merritt phenomenon does not occur with common hemangioma, rather it is associated with the more aggressive Kaposiform hemangioendothelioma and rarely with other vascular neoplasm. We report the case of an adult who was diagnosed as Kaposiform hemangioendothelioma complicated by Kasabach-Memtt phenomenon. This is the first report in Korea of an adult with Kasabach-Merritt phenomenon who has osteolytic changes of femur, pelvic bone, and lumbar spine.

PURPOSE: Trampoline-related injuries are steadily increasing. To our knowledge, there have been very few studies on trampoline injuries in Asia. The purpose of this study is to report the characteristics of pediatric trampoline injuries in Korea. MATERIALS AND METHODS: We conducted a nationwide retrospective cohort study. Data were collected from prospective nationwide databases (Emergency Department-based Injury In-depth Surveillance databases of the Korea Centers for Disease Control and Prevention) for patients who visited emergency departments (EDs) after injuries during 2011–2016. RESULTS: Of 263712 patients between 0 and 17 years of age, 2799 patients with trampoline injuries visited EDs. The median age of the patients was 5 years (interquartile range, 3–8 years), and 63% of the patients were under 6 years old. Of the patients, 1526 (54.2%) were male. Seventy-six percent of injuries occurred at trampoline parks. Trampoline injuries and trampoline park injuries have increased steadily, while ages at injury have gradually decreased year by year (p < 0.001). Injury locations included the lower extremity (47%), head and face (24%), and upper extremity (24%). A fracture was sustained by 886 (31.7%) patients. The distal humerus and proximal tibia were the most common fracture sites (34% and 23%, respectively). Fractures occurred more commonly in trampoline parks than in homes (33.7% vs. 21.1%, p < 0.001). CONCLUSION: In Korea, pediatric trampoline injuries and trampoline park injuries have tended to increase, while ages at injury have tended to decrease. Policies to prevent trampoline injuries are needed.

BACKGROUND AND OBJECTIVES: This study is aimed to investigate the efficacy of dexamethasone and methylprednisolone when used for Intratympanic steroid injection (ITSI) concurrent with systemic steroid as primary therapy. SUBJECTS AND METHOD: We undertook a retrospective study of 106 patients diagnosed with Idiopathic Sudden Sensorineural Hearing Loss at our institution. These patients were divided into the following groups based on their intratympanic steroid medications: Group 1 (which received dexamethasone for ITSI) and Group 2 (which received methylprednisolone for ITSI). The severity of pain after ITSI was also compared using Visual Analogue Scale. RESULTS: The therapeutic results of both groups showed no significant difference. The improvement of pure tone audiometry average threshold were 18.3±19.5 dB for Group 1 and 22.4±25.8 dB for Group 2, with no significant differences (p=0.402). The recovery rate according to Siegel's criteria were 34/70 (48.6%) and 18/36 (50.0%) respectively, with no significant differences (p=0.889). The degree of pain after ITSI were 1.51±1.06 and 3.92±1.63 for Group 1 and 2, respectively, showing significant differences (p<0.001). Again, there were no significant differences even when accompanying symptoms or severity of initial hearing loss were considered. CONCLUSION: There was no significant difference between efficacy of dexamethasone and methylprednisolone when used as primary therapy. Methylprednisolne caused more severe pain after ITSI, suggesting the choice of dexamethasone. Further studies are needed about the concentration of injected steroid.

Difficult common bile duct (CBD) stones are difficult to remove using conventional stone clearance methods such as endoscopic papillary sphincterotomy. In this guideline, we present several recommendations and relevant information on the endoscopic treatment of difficult CBD stones. For the primary treatment of large CBD stones in patients without distal bile duct stricture, we recommend limited endoscopic sphincterotomy followed by endoscopic papillary large balloon dilation. For large CBD stones that are difficult to remove with conventional endoscopic treatment methods, we recommend electrohydraulic or laser lithotripsy under cholangioscopy. Short-term biliary stenting is recommended in patients with CBD stones that are difficult to remove by these methods. Finally, endoscopic treatment via small bowel enteroscopy or percutaneous transhepatic cholangioscopy may be an option in patients with surgically altered anatomy.
