The oncologic safety and feasibility of laparoscopic D2 gastrectomy for advanced gastric cancer are still uncertain. The aim of this study is to compare our results for laparoscopic D2 gastrectomy with those for open D2 gastrectomy. Between 1998 and 2008, a total of 336 patients with clinical T2, T3, or T4 tumors underwent laparoscopic (n = 186) or open (n(More)
Laparoscopic inguinal hernia repair (LH) requires similar scar size to traditional open repair. To perform LH with minimal access, finer instruments were used. A 5-mm laparoscope was inserted from the umbilicus, and surgical instruments were inserted through 5- and 3-mm trocars to perform LH by the transabdominal preperitoneal approach. Polyester mesh was(More)
Suprapancreatic lymph node (LN) dissection is critical for gastric cancer surgery. Until currently, a number of laparoscopic gastrectomy procedures have been performed in the same manner as open surgery procedures [3, 4, 6]. Using the characteristic of laparoscopic surgery, the authors developed a new technique of suprapancreatic LN dissection. After(More)
BACKGROUND The effects of anastomotic complications after laparoscopically assisted gastrectomy (LAG) have not been studied widely. The aims of this observational study were to identify potential factors that predict anastomotic complications and investigate the impact of anastomotic complications in patients undergoing gastrectomy for early gastric cancer.(More)
In patients having locally advanced cancer of the stomach with suspected tumor infiltration to the pancreatic head or the duodenum, a concurrent pancreaticoduodenectomy with gastrectomy is occasionally prerequisite to achieve a microscopically tumor-free surgical margin. We present the first series of successful totally laparoscopic pancreaticoduodenectomy(More)
A significant reduction of EphA7 expression in human colorectal cancers was shown using semiquantitative reverse transcription-polymerase chain reaction analysis in 59 colorectal cancer tissues, compared to corresponding normal mucosas (P=0.008), and five colon cancer cell lines. To investigate the mechanism of EphA7 downregulation in colorectal cancer, we(More)
Orotate phosphoribosyltransferase (OPRT; EC 2.4.2.10), a key enzyme that catalyzes one of the primary steps in the phosphorylation of fluoropyrimidine, was recently recognized as an important enzyme that determines the anticancer effects of the dihydropyrimidine dehydrogenase-inhibitory fluoropyrimidine, S-1. Levels of OPRT were examined in 97 gastric(More)
While pneumatosis cystoides intestinalis (PCI) is a rare disease entity associated with a wide variety of gastrointestinal and non-gastrointestinal disorders, PCI associated with massive intra- and retroperitoneal free air is extremely uncommon, and is difficult to diagnose differentially from perforated peritonitis. We present two cases of PCI associated(More)
BACKGROUND Although laparoscopic gastrectomy has been recognized as a treatment of early gastric cancer, the indication for laparoscopic gastrectomy with D2 lymph node dissection has remained controversial. D2 lymph node dissection is considered to be feasible for advanced gastric cancer in some high-volume institutions specifically trained for the(More)
