A laparoscopic wedge resection for a submucosal tumor, which is close to the gastroesophageal junction, is technically challenging. This can be a dilemma to both patients and surgeons when the tumor margin involves the gastroesophageal junction because a wedge resection in this situation might result in a deformity of the gastroesophageal junction or an(More)
A debate is currently ongoing about whether a large gastrointestinal stromal tumor (GIST) should be treated by the laparoscopic approach because of the increased risk of tumor rupture during manipulation of the tumor with laparoscopic instruments and the resultant peritoneal tumor dissemination. Herein, we report a case of a large GIST of the stomach which(More)
PURPOSE Leptin plays an important role in the control of body weight and also has a growth-factor-like function in epithelial cells. Abnormal expression of leptin and leptin receptor may be associated with cancer development and progression. We evaluated the relationship among leptin and leptin receptors polymorphisms, body mass index (BMI), serum leptin(More)
Background. The aim of this study is to evaluate the incidence of gallstone after gastrectomy, risk factors for gallstone formation, and the surgical outcome of cholecystectomy after gastrectomy. Methods. A total of 2480 gastric cancer patients who underwent curative resection at two institutions between January 1997 and December 2012 were retrospectively(More)
PURPOSE The aim of this study was to compare the short-term surgical and long-term functional outcomes of Billroth I, Billroth II, and Roux-en-Y reconstruction after laparoscopic distal gastrectomy. MATERIALS AND METHODS We retrospectively collected data from 697 patients who underwent laparoscopic distal gastrectomy for operable gastric cancer between(More)
Fanconi anemia (FA) is a rare genetic disorder affecting multiple body systems. Genetic testing, including prenatal testing, is a prerequisite for the diagnosis of many clinical conditions. However, genetic testing is complicated for FA because there are often many genes that are associated with its development, and large deletions, duplications, or(More)
Plain radiographs of an 88-year-old woman who had experienced vomiting and abdominal distention for 3 days revealed a severely obstructed ileus, and abdominopelvic computed tomography revealed an incarcerated Morgagni hernia. The endoscope was passed through the constrictions from the diaphragmatic indentations and a thin catheter was placed for(More)
BACKGROUND A newborn screening (NBS) program has been utilized to detect asymptomatic newborns with inherited metabolic diseases (IMDs). There have been some bottlenecks such as false-positives and imprecision in the current NBS tests. To overcome these issues, we developed a multigene panel for IMD testing and investigated the utility of our integrated(More)
Hereditary spastic paraplegia (HSP) is a genetically heterogeneous group of diseases characterized by insidiously progressive lower-extremity weakness and spasticity. Spastic paraplegia 4 (SPAST) is the most common type of uncomplicated autosomal dominant HSP (40% of such cases), and spastic paraplegia 3A (ATL1) is the second most common. Here, we conducted(More)
PURPOSE We hypothesized that gastroesophageal reflux disease (GERD) would be more prevalent after a gastric wedge resection of a submucosal tumor (SMT) located close to the gastroesophageal junction (GEJ) than after a gastric wedge resection of an SMT at other locations because of the damage to the lower esophageal sphincter during surgery.
