An 83-year-old woman underwent an examination for right lower abdominal pain and was diagnosed with highly advanced cecal cancer. CT showed no metastasis; thus, we attempted resection or bypass surgery. While no liver metastasis or peritoneal dissemination was observed intraoperatively, the circumflex region was highly infiltrated to the peritoneum and retroperitoneum.

Background:  Primary neuroendocrine tumors of the gallbladder (GB-NETs) are rare, accounting for 0.5% of all NETs and 2.1% of all gallbladder cancers.

An 84-year-old man on hemodialysis was referred to our department for an advanced gastric cancer with pyloric stenosis. Pre-operative CT showed thickening of the stomach wall at the primary lesion and regional lymph node metastasis, while no clear peritoneal metastasis was found. However, we found peritoneal disseminations during the operation, so gastrojejunal bypass was performed.

In general, gastrojejunal bypass is performed for unresectable gastric cancers with stenosis. It enables patients to take food and be discharged from the hospital earlier. Previously, we used to primarily perform open gastrojejunal bypass; however, recently, we perform laparoscopic gastrojejunal bypass because it is minimally invasive.

Background: The management of acute or, in particular, chronic antibody-mediated rejection (AMR) resulting from donor-specific HLA antibodies (DSA) is a critical barrier to obtaining better long-term graft survival. To ascertain the efficacy of anti-AMR therapies, the transition of intra-graft DSA (g-DSA) was assessed.

Methods: Allograft biopsy specimens were analyzed by graft immunocomplex capture fluorescence analysis, as previously described.

Background: Arteriovenous fistula (AVF) trouble in a dialysis patient sometimes results in severe forearm ischemia.

Case Presentation: We present the case of 27-year-old man with severe steal syndrome complained of AVF malfunction. There was a condition where an upstream artery of AVF is occluded and AVF is maintained by regurgitation from the palmar arch with ischemic digits.

Digital ischemia is a serious problem in peripheral artery diseases (PAD) patients. Case 1: A 60-year-old woman with large arteriovenous fistula (AVF) complained of digital ischemia symptoms. The patient underwent dissection of AVF and distal bypass to the palmar arch with successful repair.

Objective: To evaluate the utility and safety of high-dose mizoribine combination therapy using cyclosporine and tacrolimus as calcineurin inhibitors in patients undergoing kidney transplant.

Methods: The present study enrolled 156 patients who received kidney transplants in 18 institutions between 2009 and 2013. ABO-incompatible and/or pre-sensitized recipients were excluded.

Introduction: Syringomatous adenoma of the nipple is a very rare benign tumor. To the best of our knowledge, there are no reports of a syringomatous adenoma of the nipple metastasizing, although these tumors are known to infiltrate locally and to recur if not totally resected.

Case Presentation: Our patient was a 41-year-old Japanese woman who complained of stiffness of her right nipple with abnormal discharge.

Introduction: The rates of pancreatic cancer development in the early stages of growth remain unclear; but it is generally believed that they demonstrate a rapid degree of progression. There is evidence to suggest that pancreatic cancers measuring less than 1cm demonstrate better survival rates, hence it is clear that detecting pancreatic cancers less than 1cm in size is of paramount importance. However, to date, there has been no scientifically adequate research to show the growth rate of small pancreatic cancers less than 1cm in the early stages.

Background: Mizoribine (MZR) has been developed as an immunosuppressive agent, but has a less potent immunosuppressive effect up to 3 mg/kg/day MZR. Therefore, we investigated whether high-dose MZR, at 6 mg/kg/day, would be effective and safe for kidney transplant patients in conjunction with cyclosporine (CsA), basiliximab, and corticosteroids.

Methods: A total of 40 living related patients were administered MZR (6 mg/kg/day), CsA (7 mg/kg/day), prednisolone (maintenance dose 10 mg/day), and basiliximab (20 mg/body).

Introduction: When a patient who had renal replacement therapy becomes older, an elder donor candidate may be considered as a potential donor for living-related transplantation. Elder donor candidate might have pre-existing disease including mild renal dysfunction, such as proteinuria. Marginally appropriate donors might be considered for renal graft because of the shortage of donors.

A lack of deceased kidney donors in Japan has led to dependence on living donors in as many as 80% of cases. At the same time, indications for living-donor kidney donation have been expanding in terms of donor medical status as well as HLA matching and ABO compatibility, thus emphasizing the donor shortage. To facilitate final medical decision-making for living kidney donation, we attempted kidney biopsy in six donor candidates who had problems such as mild diabetes and slight proteinuria.

Background: The lack of deceased donors in Japan means that living-donor kidney transplantation is necessary in as many as 80% of cases. However, there are few data on perioperative complications and long-term outcome for live kidney donors.

Methods: To determine associated perioperative morbidity and long-term mortality among live kidney donors, we reviewed 601 donor nephrectomies performed at our institution between 1970 and 2006 and attempted to contact all of the donors (or their families) to ascertain their present physical status.

A 51-year-old female received a kidney transplant, donated by her husband. The patient was induced with tacrolimus, mycophenolate mofetil and prednisolone. After methyl prednisolone pulse therapy without biopsy, allograft biopsy on POD 160 showed severe tubulo-interstitial nephritis with intranuclear inclusions.

Background: Nontraumatic osteonecrosis of the femoral head (ONFH) is caused by disruption of blood flow. This disease often occurs in association with steroid treatment. The pathology of steroid-induced ONFH remains unclear, although abnormalities in lipid metabolism have been reported to be involved.

Objective: Osteonecrosis of the femoral head (ONF) is a necrosis due to disruption of the blood flow. The disease often occurs in association with corticosteroid treatment. The pathology of corticosteroid-induced ONF is unclear, although abnormalities in the coagulation and fibrinolytic systems or in the lipid metabolism have been reported to be involved.

Purpose: Kidney allografts with multiple renal arteries (MRAs) have been used with increasing frequency since the advent of laparoscopic live donor nephrectomy. To determine if MRA grafts affect the short- and long-term outcomes of grafts and patients, we analyzed 340 grafts procured by open nephrectomy.

Methods: We divided the graft recipients into five groups according to the methods used for vascular reconstruction.

Kaposi's sarcoma is an uncommon neoplasm that occasionally involves the gastrointestinal tract in immunosuppressed individuals. Infection with human herpes virus 8 is known to be necessary for developing all forms of Kaposi's sarcoma. We report a renal transplant recipient who developed visceral Kaposi's sarcoma 18 months after the transplantation.

A multicenter retrospective study was conducted in 936 living donor kidney transplant recipients treated with cyclosporine (CsA) or tacrolimus (FK) from April 1982. The influences of acute rejection, hyperlipidemia, and hypertension were estimated by Kaplan-Meier's analysis and Wilcoxon's analysis. Of 916 recipients, 532 (58.
