AIM The aim of this study was to determine the predictive factors of pathological vascular invasion as contra-indicators for ablation therapy in patients with hepatocellular carcinoma (HCC) within 3 cm and three nodules without radiological vascular invasion. METHODS Two hundred and seventeen patients with HCC within 3 cm and three nodules without(More)
Persistent pain is a serious problem that often contributes to a poor quality of life in pancreatic cancer patients. Medical management by opioid analgesics is often accompanied by side effects and incomplete pain relief. A celiac plexus block is a simple treatment which relieves pain, but the procedure demands a certain degree of proficiency and the(More)
Disruption of an anastomosis after a low anterior resection reconstructed by a double stapling technique is a relatively rare complication but leads to a severe anastomotic stricture. Furthermore, this type of stricture is usually resistant to conventional treatment. A previously developed type of staple cutter (STENO-CUTTER) was applied in order to(More)
CONTEXT In pancreatic cancer, even for patients who have undergone curative resection (R0), survival analysis has revealed a poor survival rate due to cancer recurrence. Because the operation itself might have caused the dissemination of these cancer cells, the no-touch isolation technique and extensive intraoperative peritoneal lavage may be a potential(More)
One standing problem in the therapy for pancreatic cancer is peritoneal recurrence after pancreatectomy. We have established EIPL (extensive intra-operative peritoneal lavage) therapy as a very simple and non-aggressive prophylactic treatment for peritoneal dissemination of gastric cancer patients with peritoneal free cancer cells. In this study, the impact(More)
Peritoneal carcinomatosis is the most frequent pattern of metastasis and recurrence in patients with gastric cancer, and the prognosis of those patients with peritoneal metastasis is extremely poor. Once peritoneal metastasis is formed, it is extremely difficult to overcome. EIPL (extensive intraoperative peritoneal lavage) is a quite useful and practical(More)
BACKGROUND A new anesthesia system, the E-CAIOVX (GE Healthcare) enables the continuous monitoring of oxygen consumption (VO2) and carbon dioxide elimination (VCO2) during the surgical operation. The aim of this study was to evaluate the prognostic role of intraoperative baseline VO2 and VCO2 in an emergency open abdominal operation. METHODS A total of(More)
BACKGROUND/OBJECTIVE Postoperative pancreatic fistula (POPF) is the most common and an intractable complication after pancreaticoduodenectomy (PD). Many efforts have been made to lessen POPF, but nevertheless its incidence still remains high. The aim of this study was to evaluate the efficacy of reinforcing the pancreatic remnant, but the non-reinforcement(More)
ABH-F and ABH-P have been developed for hemodiafiltration (HDF) therapy. In this study, we evaluated the solute removal characteristics of the hemodiafilters in a bovine blood in vitro study. The hemodiafilters were examined for 120 min at various filtration flow rates (Q F) (31.2–250 mL/min) under a constant blood flow rate of 250 mL/min and constant(More)
Lymph node metastasis to the iliac or inguinal region of colon cancer is extremely rare. We experienced a case of ascending colon cancer with synchronous isolated right external iliac and inguinal lymph node metastases but without any regional lymph node metastasis. An 83-year-old woman was admitted to our hospital due to anemia. Colonoscopy and computed(More)
