BACKGROUND/OBJECTIVE: Elderly patients with gastric cancer can receive standard gastrectomy or gastrectomy with reduced nodal dissection, i.e., limited surgery, in order to prevent postoperative complications. This study evaluated the feasibility of gastrectomy with limited surgery for elderly patients with gastric cancer. METHODS: A total of 267 elderly patients (≥70 years old) were divided into two groups according to the level of nodal dissection: patients who received nodal dissection according to guidelines were included in the standard surgery group (standard group), and those who received reduced nodal dissection were included in the limited surgery group (limited group)...

Colorectal cancer is seldom accompanied by venous tumor thrombosis, and little is known about the features of venous tumor thrombosis in colorectal cancer. However, some reports show that colorectal cancer patients can develop venous tumor thrombosis and warn clinicians not to overlook this complication. In this report, we perform a review of 43 previously reported cases and investigate the characteristics of colorectal cancer accompanied by venous tumor thrombosis. The histological type of more than half of the cases was moderately differentiated adenocarcinoma, which is known to be aggressive...

This review describes the recent advances in, and current status of, minimally invasive pancreatic surgery (MIPS). Typical MIPS procedures are laparoscopic pancreaticoduodenectomy (LPD), laparoscopic distal pancreatectomy (LDP), laparoscopic central pancreatectomy (LCP), and laparoscopic total pancreatectomy (LTP). Some retrospective studies comparing LPD or LDP and open procedures have demonstrated the safety and feasibility as well as the intraoperative outcomes and postoperative recovery of these procedures...

BACKGROUND: The incidence of postoperative pancreatic fistula (POPF) after distal pancreatectomy is approximately 30%. The most serious complications of pancreatic resection, such as mortality and prolonged hospitalization, are unresolved despite the proposal of various surgical procedures. We developed a new polyglycolic acid (PGA) fabric composed of fine diameter fibers to prevent POPF, and macroscopically and microscopically evaluated the effects of applying it to the pancreatic remnant...

Laparoscopic cholecystectomy is one of the most common procedures performed worldwide. Despite advances in technique, injury to the common bile duct and blood vessels still occurs. Rouviere's sulcus, a naturally occurring cleft in the right lobe, anterior to Segment 1, occurs in over 80% of normal livers. It is a useful, but often ignored, anatomical landmark for beginning dissection of Calot's triangle, and also for confirming its location. Despite this, its usefulness is not widely known or appreciated by general surgeons...

OBJECTIVE: The aim of the present study was to investigate the association between non sentinel lymph node metastasis (NSLNM) and clinicopathological factors, particularly in the case of sentinel lymph node (SLN) metastasis in one or two, in clinically node negative patients with breast cancer. METHODS: Between 10/2010 and 10/2014, 350 sentinel lymph node biopsy (SLNB) were performed in patients with histologically proven primary breast cancer in our clinic. The data collection includes the following characteristics: age, pathological tumor size, histological type, histological grade, lymphovascular invasion (LVI), number of positive SLN, size of the SLN metastasis (macrometastasis, micrometastasis, isolated tumor cells), multifocality (MF), extracapsuler invasion (ECI) of the SLN, the estrogen receptor (ER) status, the progesterone receptor (PR) status and the Her 2 receptor status, Ki 67 reseptor status...

BACKGROUND: Routine therapy of metabolic bone disorder (MBD) after gastrectomy for gastric cancer has not been established yet. We have reported that administering an active vitamin D3 agent to patients who had undergone gastrectomy for gastric cancer improved MBD. Recently, the usefulness of alendronate, an osteoclast inhibitor, has been reported for MBD. Here we report the effects of alendronate for MBD after gastrectomy for gastric cancer. METHODS: Dual energy X-ray absorptiometry was performed consequently in 14 patients, who had been gastrectomized for gastric cancer and survived more than 5 years without recurrence, to evaluate the MBD and compared before and after treatment...

BACKGROUND AND AIMS: Postoperative ileus (POI) is one of the most common reasons for sustained hospital stays after ileostomy repair. Although many factors have been investigated as POI risk factors, the investigation of the impact of prior abdominal surgery (PAS) before rectal cancer surgery has been limited. This study aimed to identify the impact of PAS as a risk factor for POI after ileostomy repair. MATERIAL AND METHODS: A total of 220 consecutive patients with rectal cancer who underwent ileostomy repair were enrolled...

BACKGROUND: In patients with acute biliary pancreatitis (ABP), cholecystectomy is mandatory to prevent further biliary events, but the precise timing of cholecystectomy for mild to moderate disease remain a subject of ongoing debate. The aim of this study is to assess the outcomes of early versus delayed cholecystectomy. We hypothesize that early cholecystectomy as compared to delayed cholecystectomy reduces recurrent biliary events without a higher peri-operative complication rate. METHODS: Patients with mild to moderate ABP were prospectively randomized to either an early cholecystectomy versus a delayed cholecystectomy group...

BACKGROUND: Prostate cancer (PCa) is a leading cause of cancer-related death in men, which emphasizes the need for novel therapeutic approaches. Targeting microRNA (miRNA) has been considered as a therapeutic strategy against cancers. Human miR-204-5p potentially targeting BCL2 has been reported to be downregulated in various cancers. We hypothesized that miR-204-5p overexpression induces cancer cell apoptosis by repressing BCL2 expression. METHODS: A vector harboring mature miR-204-5p was constructed and delivered into human PCa cells...

Parathyroid carcinoma is a rare disease of unknown etiology. This study presents a case of parathyroid carcinoma in a patient with tertiary hyperparathyroidism. Despite a successful kidney transplantation, the intact parathyroid hormone (iPTH) level of the patient was elevated consistently and could not be controlled by medical therapy. Due to the development of tertiary hyperparathyroidism with bone pain and osteoporosis, subtotal parathyroidectomy was performed 4 months after the kidney transplantation. Histological evaluation revealed that one of four parathyroid lesions was a parathyroid carcinoma, while the others were diffuse hyperplasia...
