BACKGROUND: Breast reconstruction has become more common as mastectomy has become more frequent. In Korea, the National Health Insurance Service (NHIS) began covering breast reconstruction in April 2015. This study aimed to investigate trends in mastectomy and breast reconstruction over the past 10 years and to evaluate the impact of NHIS coverage on breast reconstruction. METHODS: Nationwide data regarding mastectomy and breast reconstruction were collected from the Korean Breast Cancer Society registry database. Multiple variables were analyzed in the records of patients who underwent breast reconstruction from January 2005 to March 2017 at a single institution. RESULTS: At Seoul National University Hospital, the total number of reconstruction cases increased 13-fold from 2005 to 2016. The proportion of immediate breast reconstruction (IBR) cases out of all cases of total mastectomy increased from 4% in 2005 to 52.0% in 2016. The proportion of delayed breast reconstruction (DBR) cases out of all cases of breast reconstruction and the overall number of DBR cases increased from 8.8% (20 cases) in 2012 to 18.3% (76 cases) in 2016. After NHIS coverage was initiated, the proportions of IBR and DBR showed statistically significant increases (P < 0.05). Among the IBR cases, the percentage of prosthesis-based reconstructions increased significantly (P < 0.05), but this trend was not found with DBR. Total mastectomy became significantly more common after the expansion of NHIS coverage (P < 0.05). CONCLUSIONS: Over the last decade, there has been an increase in mastectomy and breast reconstruction, and the pace of increase accelerated after the expansion of NHIS coverage. It is expected that breast reconstruction will be a routine option for patients with breast cancer under the NHIS.

Intertrochanteric fractures are common in older age group. Recently better implant design and surgical technique have improved clinical results. But still many patients suffer from high morbidity and mortality, because of accompanying osteoporosis and various senile diseases. From January 1991 to June 1994, we treated 54 patients older than 70 years with intertrochanteric fractures of femur. Among them, 23 patients were followed up at our hospital and the other patients were informed from police station. Lost follow up was ten patients and final follow up were 44 patients. Mortality was analyzed for the detection of causative factors, such as age, sex, associated medical problems. type of fracture, degree of osteoporosis, type of operation, internal between injury and operation and duration of admission. The results were as follows; 1. 26 patients survived and 18 patients died(Mortality rate :40.9%) 2. 10 patients died within 1 year(Mortality rate :22.7%) 3. Mortality was related to associated medical problems, interval between in jury and operation and type of fracture, which were statistically significant(P < 0.05).

BACKGROUND/AIMS: Radiofrequency ablation (RFA) has been mostly used as a therapeutic alternative to hepatic resection for treating liver metastasis of colorectal cancer. The purpose of the present study was to determine whether there were differences in outcome between RFA and surgical resection in the treatment of colorectal cancer with liver metastases. METHODS: We performed a retrospective analysis of 53 patients who underwent only hepatic resection or only RFA for colorectal liver metastases. Twenty-five patients who underwent hepatic resection were compared with 28 patients who underwent RFA for synchronous or metachronous liver metastases. RESULTS: The median CEA level at the time of diagnosis of liver metastases was significantly higher in the resection group (14.2 ng/mL vs. 2.8 ng/mL, p=0.002). The median size of main liver metastases was significantly larger in the resection group (4.0 cm vs. 2.05 cm, p=0.002). There was no difference in the percentage of patients experiencing major complication (one patient in each group). The marginal recurrence rate was significantly higher in the RFA group (p=0.004). Disease-free and overall survival were longer in the resection group (p=0.008 and 0.017, respectively). In multivariate analysis, only the type of treatment was a factor associated with disease-free and overall survival (p=0.004 and 0.007, respectively). CONCLUSIONS: Because of the high marginal recurrence rate, RFA shows an inferior outcome in comparison with surgical resection. Therefore, RFA should be considered for only selected patients with unresectable (by any means) disease or with high operative risk.

PURPOSE: This study was undertaken to evaluate retrospectively the clinical results of surgery for the rectal villous adenoma. METHODS: The study took place from the period of Mar. of 1988 to Feb. 1998 at the Dept. of Surgery, Sungkyunkwan Univ., Medical college. The study consisted of : Among the 97 cases diagnosed with colon & rectal villous adenoma, and 59 were rectal villous adenoma, and 42 cases underwent resection. We focused on these 42 cases, especially on the position of tumor, its size, surgical technique, histologic results & keeping close follow up post-surgically. RESULTS: The sex ratio was 2:1 with male predominence, 18 cases were in their fifties with the average age of 55. In 30 cases, the lesion was situated within the 8 cm of anal verge. The average size of tumor was 3.64 cm. The applied methods were; rectotomy 19 cases, anterior resection 13 cases (including low anterior resection), endoscopic excision and transanal excision were 7 cases, and 2 cases, respectively. And in one case where the tumor size was 14.5 cm and which was situated within 3 cm of anal verge, Miles' operation was conducted. Death due to post-operative complication was not observed. 2 cases of wound infection in postoperation, one case of transient urinary incontinence & hematoma were found. And in the case of explo-laparotomy, anastomosis site leakage, in one case, anastomosis site stricture in 2 cases were noted. malignant cells were observed in total of 73.8%, among these, 80% were from villous adenoma, 70% from tubullovillous adenoma. In the case of tumor size less 1 cm, and tumor size greater than 1 cm, the probability of finding malignant lesion were 33.3% and 76.9%, respectively. CONCLUSIONS: We suggest that wideexcision through York-Mason approach is a safe and effective technique for huge villous adenomas of the rectum.

Klebsiella ornithinolytica is a very rare Klebsiella species isolated from human. Human strains have been isolated mainly from respiratory secretions, wounds and urine. The clinical features and pathogenic role of human disease with K. ornithinolytica is unknown. We describe a case of K. ornithinolytica bacteremia which developed in a 45-year-old man with acute cholangitis by common bile duct stones. In this case, K. ornithinolytica was sensitive to beta-lactamase inhibitor, all tested cephalosporins, aminoglycosides, quinolones, trimethoprim/sulfameth- oxazole but resistant to ampicillin. After intravenous therapy with cefotaxime, follow up blood culture showed no further growth of K. ornithinolytica. Later, extended-spectrum beta-lactamase (ESBL) producing Klebsiella pneumoniae and Escherichia coli was cultured from bile, so the antibiotics was switched to meropenem. Common bile duct stones was removed by percutaneous transhepatic cholangioscopy (PTCS) and the patient recovered fully without any complication.

Wegener's granulomatosis is a necrotizing,granulomatous vasculitis that involves multiple organs including the upper and lower respiratory tract and the kidney.The kidney initially exhibits focal necrotizing glomerulonephritis,which progresses to crescentic glomerulonephritis in Wegener's granulomatosis.We experienced a case of Wegener's granulmatosis which was associated with a thin glomerular basement membrane disease.The patient suffered from nasal stuffiness,recurrent serous otitis media,and tinnitus.Despite antibiotic therapy and ventral tube insertion,symptoms did not improve and hearing difficulty was aggravated.Ulcerative,necrotizing granulomatous inflammations with multinucleated giant cells were seen on nasal biopsy.She had recurrent microscopic hematuria and the renal biopsy findings by light and immunofluorescent microscopy did not reveal any abnormalities but diffuse thinning of the glomerular basement membrane (226nm)was observed by electronmicroscopy. With the above clinical findings and biopsy results,we diagnosed Wegener's granulmatosis with thin glomerular basement membrane disease.Thin glomerular basement membrane disease,also called benign recurrent hematuria,is characterized by diffuse thinning of the glomerular basement membrane and hematuria. Weekly low-dose methotrexate together with prednisone was used as treatment regimen because nonglomerular microscopic hematuria may be the first sign of cyclophosphamide-induced renal toxicity.With the above combination therapy, she felt well-being sense and her hearing difficulty was also much improved. She has been treated as an outpatient with glucocorticoid.

PURPOSE: Conventional laparoscopic appendectomy is performed using three ports, and single-port appendectomy is an attractive alternative in order to improve cosmesis. The aim of this study was to compare pain after transumbilical single-port laparoscopic appendectomy (SA) with pain after conventional three-port laparoscopic appendectomy (TA). METHODS: From April to September 2011, 50 consecutive patients underwent laparoscopic appendectomy for simple appendicitis without gangrene or perforation. Patients who had undergone appendectomy with a drainage procedure were excluded. The type of surgery was chosen based on patient preference after written informed consent was obtained. The primary endpoint was postoperative pain evaluated by the visual analogue scale score and postoperative analgesic use. Operative time, recovery of bowel function, and length of hospital stay were secondary outcome measures. RESULTS: SA using a SILS port (Covidien) was performed in 17 patients. The other 33 patients underwent TA. Pain scores in the 24 hours after surgery were higher in patients who underwent SA (P = 0.009). The change in postoperative pain score over time was significantly different between the two groups (P = 0.021). SA patients received more total doses of analgesics (nonsteroidal anti-inflammatory drugs) in the 24 hours following surgery, but the difference was not statistically significant. The median operative time was longer for SA (P < 0.001). CONCLUSION: Laparoscopic surgeons should be concerned about longer operation times and higher immediate postoperative pain scores in patients who undergo SA.

BACKGROUND: Lipomas are benign neoplasms composed of mature fat cells. Current treatments are invasive and carry the risk of scarring. For this reason, phosphatidylcholine (PPC) formula has been widely used to treat areas of localized fat accumulation. However, there are few reports on injection lipolysis with injection of PPC formula. OBJECTIVE: The purpose of this study was to investigate whether injection lipolysis with PPC formula is an effective therapeutic option for patients with lipoma. METHODS: Twenty-two lipomas in 7 patients were included. Three sessions at intervals of 6 to 8 weeks were done. Sonographic measurements of lipoma size were repeated before each session. Any side-effects and the patients' satisfaction were noted. In one lipoma, histological changes after lipolysis were described. RESULTS: After three sessions, a significant reduction in lipoma size of 47.4% was achieved. Histology showed a fibrosis with loss of adipocytes. Inflammation occurred in one case, so the patient was excluded from this study. Transient burning sensation and swelling at the injection site were the most common adverse effects. No severe side-effects or systemic reactions were observed. CONCLUSION: Treatment of lipoma with PPC formula has the potential to be a patient-friendly and well-tolerated therapy that can achieve cosmetically pleasing treatment outcomes.

PURPOSE: To use the clinical and radiological data to differentiate non-cholesterol versus cholesterol gall bladder (GB) polyps, which can be useful in deciding the treatment of the patient. METHODS: One hundred and eighty-seven patients underwent cholecystectomy for GB polyps of around 10 mm for 10 years, and were divided into two groups, cholesterol polyps (146 patients) and non-cholesterol polyps (41 patients) based on the postoperative pathological findings. Gender, age, body weight, height, body mass index (BMI), symptoms, laboratory findings, size, number of polyps, presence of GB stone and maximum diameter measured by preoperative ultrasonography (USG), computed tomography (CT), and pathological diameter were subjected to comparative analysis. RESULTS: Patients diagnosed with cholesterol polyps were younger in age and had higher BMI, and the total cholesterol levels and white blood cell levels were higher, but were not statistically significant. It was notable to see that 28.6% of the cholesterol polyps were not found in the preoperative CT yet the percentage of the undetectable rate was significantly lower (8%) in the non-cholesterol polyp group. There was a discrepancy in maximum diameters between the two radiological methods in both groups but the discrepancy was significantly larger in the cholesterol polyp group. CONCLUSION: The clinical signs that can be helpful to diagnose whether it is a cholesterol polyp or not are younger patients who have high BMI, polyps which are detectable only on the USG and large maximum diameters between the USG and CT. And if the discrepancy of the maximum diameter is lesser than 1mm the polyp may be considered as a non-cholesterol polyp.
