One Year Experience of Iliac Bifurcated Device for Aortoiliac Aneurysm in a Korean Single Center.

One of the predominant methods for preserving the internal iliac artery (IIA) in aortoiliac aneurysms is to use an iliac bifurcated device (IBD). However, there are a few limitations to the use of IBD in Korea. Our study aims to present the technical aspects of these devices, and to provide a mid-term analysis of IBD.

Midterm Outcome of Femoral Artery Stenting and Factors Affecting Patency.

Purpose: The purpose of this study was to evaluate the early and midterm results of superficial femoral artery (SFA) stenting with self-expanding nitinol stents and to identify the factors affecting patency.

Materials And Methods: SFA stenting was performed in 165 limbs of 117 patients from January 2009 to December 2013. Patients were followed-up for the first occurrence of occlusion or stenosis based on computed tomography and duplex scan results and a decrease in ankle brachial index of >15%.

Vascular disease prevalence and risk factors in a screened Korean male population.

Background: Vascular diseases, such as carotid artery stenosis (CAS), abdominal aortic aneurysm (AAA), and peripheral arterial occlusive disease (PAD) of the lower limb, are common in elderly men. These diseases have not been thoroughly reported in Eastern countries as well as in Western countries. We compare the prevalence rates in Korea with previous reports, and evaluate correlations between known risk factors and these conditions in this population.

The effect of duodenojejunal bypass for type 2 diabetes mellitus patients below body mass index 25 kg/m(2): one year follow-up.

Purpose: The goals of this study are to evaluate the effect of duodenojejunal bypass (DJB) for type 2 diabetes mellitus (T2DM) patients below body mass index (BMI) 25 kg/m(2) in one year follow-up, and to compare the results of 1 week which we have reported in 2011.

Methods: In this prospective observational study, there were 31 type 2 diabetic patients who underwent DJB at Inha University Hospital from July 2009 to January 2011. We did laboratories such as 75-g oral glucose tolerance test (OGTT), insulin level and hemoglobin A1c (HbA1c), etc.

Validation of the Korean translation of obesity-related problems scale assessing the quality of life in obese Korean.

Purpose: The objective of this study was to translate the obesity-related problems (OP) scale for Koreans and to validate it for use in Korean populations.

Methods: Translation and back-translation of the OP scale was performed and a pilot test was conducted. Following this, patients who had received treatment at the Obesity Center of Inha University Hospital were selected for participation in the field test.

Pyrophosphatase overexpression is associated with cell migration, invasion, and poor prognosis in gastric cancer.

Inorganic pyrophosphatase (PPase) catalyzes the hydrolysis of pyrophosphate to form orthophosphate. Pyrophosphate can substitute for ATP under certain circumstances. We previously conducted a proteomic analysis to investigate tumor-specific protein expression in gastric cancer, and PPase was identified as a potential gastric tumor-specific marker; it was therefore selected for further study.

Influence of gastrectomy for stomach cancer on type 2 diabetes mellitus for patients with a body mass index less than 30 kg/m(2).

Purpose: The impressive effect of LRYGBP on mildly obese patients (30 kg/m(2) < BMI < 35 kg/m(2)) with T2DM raises the argument for lowering the threshold for surgical intervention to non-obesity (BMI < 30 kg/m(2)). The goal of this study was to evaluate the effect of gastrectomy on non-obese patients with T2DM and what preoperative clinical factors are associated with postoperative long term improvement.

Methods: In this retrospective review, we analyzed the change in diabetic status in 75 patients with gastric cancer undergoing three different gastrectomies in a single institution from June 1996 to September 2009.

Efficacy and feasibility of laparoscopic subtotal cholecystectomy for acute cholecystitis.

Backgrounds/aims: For patients with acute cholecystitis, conversion from laparoscopic cholecystectomy to open surgery is not uncommon due to possibilities of serious hemorrhage at the liver bed and bile duct injury. Recent studies reported successful laparoscopic subtotal cholecystectomy for acute cholecystitis. The purpose of this study was to determine the efficacy and feasibility of such an operation based on the experience of surgeons at our facility.

Three-weekly s-1 monotherapy as first-line treatment in elderly patients with recurrent or metastatic gastric cancer.

Background/aims: Elderly patients with advanced gastric cancer (AGC) have generally been excluded from clinical trials, and there are few data available on the treatment of these patients. The efficacy of palliative S-1 monotherapy as a first-line treatment regimen for elderly patients has not been well elucidated.

Methods: For this study, 25 AGC patients were enrolled between January 1, 2007 and March 31, 2009; 4 cases were recurrent AGC and 21 cases were metastatic AGC at the time of diagnosis.

Risk factors affecting pancreatic fistulas after pancreaticoduodenectomy.

Aim: To analyze the risk factors of pancreatic leakage after pancreaticoduodenectomy.

Methods: We retrospectively reviewed 172 consecutive patients who had undergone pancreatico-duodenectomy at Inha University Hospital between April 1996 and March 2006. We analyzed the pancreatic fistula rate according to the clinical characteristics, the pathologic and laboratory findings, and the anastomotic methods.

Effect of preoperative biliary drainage on surgical results after pancreaticoduodenectomy in patients with distal common bile duct cancer: focused on the rate of decrease in serum bilirubin.

Aim: To examine if the rate of decrease in serum bilirubin after preoperative biliary drainagecan be used as a predicting factor for surgical complications and postoperative recovery after pancreaticoduodenectomy in patients with distal common bile duct cancer.

Methods: A retrospective study was performed in 49 consecutive patients who underwent pancreaticoduodenectomy for distal common bile duct cancer. Potential risk factors were compared between the complicated and uncomplicated groups.

Gasless endoscopic thyroidectomy via an anterior chest wall approach using a flap-lifting system.

Purpose: Endoscopic thyroidectomy (ET) requires a proper working space for adequate visualization of anatomical structures and proper instrument manipulation. The purpose of this prospective study was to estimate the feasibility and safety of ET using an anterior chest wall approach without gas insufflation.

Materials And Methods: The working space was created under a direct and endoscopic view through a 3-cm incision on the anterior chest wall.

Tc-99m ciprofloxacin imaging in acute cholecystitis.

Aim: To evaluate the efficacy of a new nuclear imaging Infecton (Tc-99m ciprofloxacin) for the diagnosis of acute cholecystitis.

Methods: Sixteen patients thought to have acute cholecystitis were included in this study. The diagnosis of acute cholecystitis was made based on clinical symptoms and ultrasonographic and pathologic findings.

Eosinophilic gastroenteritis presenting as small bowel obstruction: a case report and review of the literature.

Eosinophilic gastroenteritis is a rare disease of unknown etiology. It is characterized by eosinophilic infiltration of the bowel wall to a variable depth and symptoms associated with gastrointestinal tract. Recently, the authors experienced a case of eosinophilic gastroenteritis presenting as small bowel obstruction.

Surgical clips found at the hepatic duct after laparoscopic cholecystectomy: a possible case of clip migration.

Surgical clip migration and subsequent stone formation in the common bile duct is a rare but well-established complication after laparoscopic cholecystectomy. There are some suggestions about the mechanisms of the migration process, but the details are still unclear. We report here a case in which common bile duct stones were formed around surgical clips, and other clips were found to have penetrated into the common hepatic duct, which we believe were in the process of migration after laparoscopic cholecystectomy.

Effective transduction of osteogenic sarcoma cells by a baculovirus vector.

Efficient gene delivery of a baculovirus-derived vector (BV-p53-lacZ) to a human osteogenic sarcoma cell line, Saos-2, was serendipitously found while evaluating the vector for gene delivery to human p53-null tumour cells in a previous study. Therefore, we investigated other human, rat and mouse osteogenic sarcoma and other types of tumour cell lines for transduction efficiency via baculovirus vectors containing a lacZ reporter gene under the control of either a cytomegalovirus or Rous sarcoma virus promoter. The expression of beta-galactosidase protein, assessed by X-Gal staining and beta-galactosidase ELISA, demonstrated an extremely high level of transduction efficiency in some osteogenic sarcoma cell lines, such as U-2OS, Saos-2 and Saos-LM2.

Ex vivo expansion and clonality of CD34+ selected cells from bone marrow and cord blood in a serum-free media.

Although umbilical cord blood is increasingly being used in allogeneic marrow transplantation, delayed platelet engraftment is often a concern for cord blood transplant recipients. We evaluated the potential of ex vivo expansion and clonality in CD34+ cells separated from a bone marrow source, and cord blood, in a serum-free Media. The CD34+ cells, selected from bone marrow (BM) and umbilical cord blood (CB), were expanded with hematopoietic growth factors.
