The hypolipidemic and hypoglycemic effects of two dietary dosages (0.1% and 0.5%) of water and 80% ethanol extracts from hot-air dried Orostachys japonicus A. Berger were evaluated in the serum and organ tissues of streptozotocin-induced diabetic rats. The STZ-induced diabetic groups supplemented with the O. japonicus extracts showed significantly higher body weight compared to a diabetic control group at the end of experiment. The extracts exhibited substantial hypoglycemic effects by significant reductions of fasting blood glucose levels at all time points tested compared to the initial stage before treatment of the extracts. Declines of serum and hepatic triglyceride levels were greater than declines of total cholesterol in the groups treated with the 0.5% O. japonicus extract (DBW2 and DBE2) when compared to the DBC group. Hepatic glycogen content was higher in the groups treated with O. japonicus extract, while lipid peroxide content was decreased in these treated groups compared to the DBC group. Hepatic antioxidant activity was significantly increased in the groups supplemented with the O. japonicus ethanol extract. The hypolipidemic and hypoglycemic effects of the O. japonicus ethanol extract were significantly greater than the effects of the water extract. Based on this study, it seems that O. japonicus ethanol extract, due to its higher phenolic and flavonoid components than the water extract, may control blood glucose and alleviate hyperlipidemia in diabetes.

To compare the rate of success and incidence of complications associated with currently popular routes of percutaneous central venous cannulation, we studied 131 patients in whom central venous catheterization was attempted. Right or left external jugular veins were used in 67 cases, and success rate was 9796. Right internal jugular veins were used in 27 cases, and success rate was 100%. Right or left basilic veins were used in 21 cases, and success rate was 76%. Right or left subclavian veins were used in 16 cases, and 75% of success rate. Non-J-wire type catheters were utilized in 60 cases, and success rate was 88%. J-wire type catheters were used in 71 eases, and success rate was 94%. We found 2 cases of catheter curling in Non-J-wire type catheters.

PURPOSE: The aim of this study was to investigate the risk factors for conversion to conventional laparoscopic cholecystectomy (CLC) in single incision laparoscopic cholecystectomy (SILC) along with the proposal for procedure selection guidelines in treating patients with benign gallbladder (GB) diseases. METHODS: SILC was performed in 697 cases between April 2010 and July 2014. Seventeen cases (2.4%) underwent conversion to conventional LC. We compared these 2 groups and analyzed the risk factors for conversion to CLC. RESULTS: In univariate analysis, American Society of Anesthesiologist score > 3, preoperative percutaneous transhepatic GB drainage status and pathology (acute cholecystitis or GB empyema) were significant risk factors for conversion (P = 0.010, P = 0.019 and P < 0.001). In multivariate analysis, pathology (acute cholecystitis or GB empyema) was significant risk factors for conversion to CLC in SILC (P < 0.001). CONCLUSION: Although SILC is a feasible method for most patients with benign GB disease, CLC has to be considered in patients with acute cholecystitis or GB empyema because it is likely to result in inadequate visualization of the Calot's triangle and greater bleeding risk.

Purpose: Sentinel lymph node biopsy (SLNB) using both a radioactive isotope (RI) and blue dye is considered highly effective; however, there were limitations with the use of both agents in some hospitals, and blue dye has been shown to have some adverse effects. Additionally, preoperative prediction of sentinel lymph node (SLN) status using the maximum standardized uptake value (SUVmax) on positron emission tomography-computed tomography (PET-CT) can help avoid unnecessary axillary dissection or SLNB. Thus, we evaluated the efficacy and oncologic safety of SLNB using an RI alone in terms of long-term outcomes and determined the association between SLN metastasis and SUVmax of the primary tumor. Methods: This retrospective study was conducted at Konyang University Hospital between March 2011 and May 2018. Overall, 142 patients with breast cancer who underwent SLNB using an RI alone were enrolled. Data on identification and false-negative rates were collected. The SUVmax of primary tumors on PET-CT were analyzed for their association with SLN metastasis. Results: The identification and false-negative rates were 98.6% and 0%, respectively. There was no axillary local recurrence in patients with negative SLN findings. The correlation between the SUVmax of the primary tumor and SLN status was significant (r=0.249, P=0.005); the cutoff value for negative SLN metastasis was <2.15. Conclusion The single agent method using an RI is not inferior to other methods and serves as a feasible option for SLNB. And the number of excised SLNs could be minimized when the SUVmax of primary tumor is extremely low.

BACKGROUND: As our population in Korea ages, more postoperative pulmonary complications (PPCs) have recently developed. There have been several studies about the predictive factors for PPC, but any consensus has not been established. In this study, we reappraised the predictive factors for PPC after general anesthesia in a population from Gyeong-ju, which was composed of elderly people. METHODS: We retrospectively investigated the incidence and predictive factors for PPC in 84 patients who underwent general anesthesia. We investigated gender, age, height, weight, BMI, smoking, underlying disease, underlying respiratory disease, malignancy, the laboratory findings (hemoglobin, albumin, arterial O2 saturation) and the pulmonary function tests of the patients. RESULTS: 84 patients were initially enrolled into the study, and PPC developed in 31 (36%) patients. The mean age of the enrolled patients was 66.515.1 years-old, so it shows the trend of an aging society. Three predictive factors were revealed that are independently associated with the PPC: site of operation (OR, 8.3), underlying disease (OR, 9.9) and serum albumin (OR, 4.0). CONCLUSIONS: Among the statistically meaningful predictive factors, underlying disease and operation site are well known from previous studies, but the albumin level<3.5 g/dL is also meaningful, which is higher than the previous reference level. It implies that the patient with a albumin level 3.0~3.5 g/dL can be classified into the high risk group. Therefore, we should recognize that it is necessary to apply more strict reference levels in an aging population to reduce the incidence of PPC.

PURPOSE: Single incision laparoscopic cholecystectomy (SILC) is increasingly performed worldwide. Accordingly, the Konyang Standard Method (KSM) for SILC has been developed over the past 6 years. We report the outcomes of our procedures. METHODS: Between April 2010 and December 2016, 1,005 patients underwent SILC at Konyang University Hospital. Initially 3-channel SILC with KSM was changed to 4-channel SILC using a modified technique with a snake retractor for exposure of Calot triangle; we called this a modified KSM (mKSM). Recently, we have used a commercial 4-channel (Glove) port for simplicity. RESULTS: SILC was performed in 323 patients with the KSM, in 645 with the mKSM, and in 37 with the commercial 4-channel port. Age was not significantly different between the 3 groups (P = 0.942). The postoperative hospital days (P = 0.051), operative time (P < 0.001) and intraoperative bleeding volume (P < 0.001) were significantly improved in the 3 groups. Drain insertion (P = 0.214), additional port insertion (P = 0.639), and postoperative complications (P = 0.608) were not significantly different in all groups. Postoperative complications were evaluated with the Clavien-Dindo classification. There were 3 cases (0.9%) over grade IIIb (bile duct injury, incisional hernia, duodenal perforation, or small bowel injury) with KSM and 3 (0.5%) with mKSM. CONCLUSION: We evaluated the evolution of the KSM for SILC. The use of the mKSM with a commercial 4-channel port may be the safest and most effective method for SILC.

PURPOSE: Single incision laparoscopic appendectomy (SILA) is a widely used surgical procedure for treatment of appendicitis with better cosmesis. However, many surgeons generally tend to choose conventional multiport laparoscopic appendectomy regarding with complicated appendicitis. The aim of this study is to demonstrate the safety and feasibility of SILA for treatment of complicated appendicitis by comparison with 3-ports conventional laparoscopic appendectomy (CLA). METHODS: Retrospective chart review of patients diagnosed appendicitis at single hospital during January 2015 to May 2017 collected 500 patients. Among 134 patients with complicated appendicitis, we compared outcomes for 29 patients who got SILA and 105 patients who got CLA. RESULTS: 179 and 321 patients were treated by SILA and CLA, respectively. 134 (26.8%) patients were treated for complicated appendicitis, 29 patients by SILA and 105 patients by CLA, respectively. There was no case converted to open or added additional trocar in both groups. There were no differences in demographics with regard to age, sex, body mass index (BMI), and American society of anesthesiologists (ASA) scores. There was no difference in mean operating time (58.97±18.53 (SILA) vs. 57.57±21.48 (CLA), p=0.751). The drain insertion rate (6.9% vs 37.1%, p=0.001) and the length of hospital stay (2.76±1.41 vs. 3.97±2.97, p=0.035) were lower in SILA group with significance. There was no significant difference in the rate of surgical site infection (6.9% vs. 6.7%, p=1.000). CONCLUSION: This study demonstrates that SILA is a feasible and safe procedure for treatment of complicated appendicitis.

PURPOSE: Myelosuppression, particularly neutropenia, is one of the most frequent and serious toxicity seen in patients with breast cancer undergoing systemic chemotherapy. However, the predictive factors for development of severe neutropenia in chemotherapy remain unknown. We therefore evaluated predictive factors for excessive myelosuppression.METHODS: We retrospectively analyzed 341 patients with breast cancer treated with chemotherapy from 2000 to 2012. Clinicopathological characteristics, number of using of granulocyte colony-stimulating factor (G-CSF), and pretreatment hematologic values were extracted from the electronic medical record system. Patients were sorted 2 groups by number of using G-CSF in each chemotherapeutic regimens; group 1 is more G-CSF (within high 20 percentile) and 2 less G-CSF using group (within lower 20 percentile).RESULTS: Number of using G-CSF was ranged 0–83 (mean 10.76). One hundred one patients were in group 1 and 65 patients were in group 2. Mean of number of G-CSF using was 0.21 in group 1 and 28.02 in group 2. Pretreatment white blood cell, hemoglobin and platelet count were lower in group 2 than in group 1 (6.88×10³/µL vs. 5.97×10³/µL, 12.63 g/dL vs. 11.90 g/dL, and 275.95×10⁴ µL vs. 227.37×10⁴ µL). There were no statistically differences in other clinicopathologic characteristics such as age, body mass index or comorbidities, hormonal receptor, stage, and other pretreatment hematologic values.CONCLUSION: Pretreatment white blood cell count, hemoglobin and platelet count can be used to identify patients at increased risk of significant myelosuppression undergoing chemotherapy with breast cancer. This information can be used to target high-risk patients for prophylactic treatment.

Purpose: Obturator hernia is a difficult disease to diagnose. If a surgical treatment is delayed in obturator hernia, a bowel resection may be required due to strangulation. The surgical treatment of this disease is to use a classical laparotomy. Recently, the laparoscopic approach has been reported and reviewed for efficiency. We checked the indicators that determine the most appropriate surgical method according to the patient’s condition. Methods: In the study, a single-institution, retrospective analysis of surgical patients undergoing an obturator hernia surgery between 2003 and 2018 was performed. The patients were divided into a laparoscopic group (5 patients underwent laparoscopic repair; no intestinal resection) and an open group (13 patients who underwent open repair; 10 with and 3 without intestinal resection). The outcomes were compared between the groups. We analyzed the relevant factors that could predict the proper method of surgery. Results: A total 18 patients were included in the study. All patients were female, with body mass index (BMI) of under 21 kg/m2. Of the various factors, only the WBC and CRP counts were the factors that had shown significant differences between the two groups. It is noted that patients with open surgery had a higher WBC counts (10406 versus 6520/μl; p=0.011) and CRP counts (7.84 vs. 0.32 mg/dl; p=0.027). Conclusion Obturator hernia can be treated with a laparoscopic surgery. The choice of surgical treatment can be considered in advance through the review of the patient’s WBC count or CRP count.
