A 57-year-old female patient received ileocecal colon resection because of colon cancer. Pathological findings showed pSSN2M0(pStage III b). After surgery, CapeOX was administered as an adjuvant chemotherapy.

A 71-year-old man with predialysis terminal renal insufficiency experienced peritoneal dissemination 1.5 years after low anterior resection for advanced rectal cancer. He received FOLFIRI therapy (70% dose); he achieved partial response (PR) under computed tomography and stable disease (SD) was maintained over a long term.

We report a case of advanced rectal cancer treated with chemotherapy, for which laparoscopic splenectomy had been effective for thrombocytopenia. A 56-year-old man suffered from advanced rectal cancer with multiple lung metastases. He underwent Hartmann's procedure and received chemotherapy with FOLFOX and FOLFIRI with bevacizumab.

During embryonic development, the head of the pancreas comprises ventral and dorsal primordia. The embryological fusion plane between the ventral and dorsal primordia reportedly separates the adult pancreas into the ventral and dorsal pancreas. The duct of Wirsung drains the ventral pancreas and terminates in the major papilla, while the duct of Santorini drains the dorsal pancreas and terminates in the minor papilla.

Surgical techniques commonly used for controlling bleeding during major liver surgery are hepatic inflow occlusion (Pringle maneuver) or total hepatic vascular exclusion (THVE), which are effective procedures of diminishing intraoperative blood loss. However, it is difficult to control retrograde bleeding from the hepatic veins using Pringle maneuver and some patients do not tolerate hemodynamic changes caused by THVE. We isolated the left and middle hepatic veins separately using Arantius' ligament approach to these hepatic veins, and extrahepatic control of the relevant to the liver segment to be resected hepatic veins with inflow control by Glissonian pedicle clamping was successfully performed.

Two-staged pancreatoduodenectomy, including exteriorization of the pancreatic juice and second-look pancreaticojejunostomy, has been recommended for high-risk patients to avoid pancreatic leakage, which often causes intra-abdominal hemorrhage. We present a new technique of interventional pancreaticojejunostomy under both fluoroscopy and endoscopy without second-look laparotomy. A 77-year-old woman with local recurrence and liver metastasis from colon cancer underwent hepato-pancreatoduodenectomy with the external drainage of pancreatic juice via the pancreatic duct tube without pancreaticojejunostomy.

Background: Growth factors, cytokines, and the renin-angiotensin system (RAS) are involved in chronic allograft dysfunction. However, it is unclear whether clinical evaluations of TGFBeta1 and the RAS in longterm stable transplant patients can predict the development of chronic allograft dysfunction.

Methods: Urinary TGFBeta1 excretion and the response of plasma renin activity (PRA) to angiotensin I converting-enzyme inhibition (ACE-I) were prospectively examined in transplant patients who had had stable graft function (n = 16) for at least 1 year after renal transplantation.

The long-term reciprocal impact of renal transplantation on infection by hepatitis B virus (HBV) is still a matter of intense debate, and the topic remains controversial. We herein report the case of a 50-year-old male asymptomatic HBV carrier who had seroconverted to positive anti-HBe antibody (Ab) and received a kidney transplantation from a cadaver donor (HB surface(s) antigen (Ag)-negative). Nine months later, his kidney function deteriorated due to chronic rejection, and hemodialysis was temporarily required.

Background: Nonspecific inflammation is the primary cause of early islet graft loss. We have shown in mice that pravastatin, a 3-hydroxy-3-methylglutaryl-coenzyme A reductase inhibitor, prevents primary nonfunction of islet isografts by reducing inflammatory reactions at the graft site. This study was designed to test the effectiveness of this agent in a large animal model, dogs, by transplanting autologous islets.
