BACKGROUND We report our long-term experience with 119 cases of N-shaped orthotopic ileal neobladder. METHODS Between March 1996 and July 2013, a total of 119 patients (102 men, 17 women) underwent cystectomy with creation of an N-shaped orthotopic ileal neobladder. The Clavien-Dindo classification score was used for grading early (<3 months postoperative), late, and pouch-related and non-pou...

A man with end-stage dilated cardiomyopathy had undergone orthotopic heart transplantation followed by heterotopic heart transplantation at the age of 52 years in 2001.1 After the procedure, he had lived uneventfully with the cooperation of 2 donor hearts working in his body. In 2009, 8 years after transplantation, the patient underwent scheduled cardiac catheterization. Retrograde cannulation ...

AIM Orthotopic models utilizing orthotopic implantation have been used for developing cancer models of multiple tumor entities. The aim of this study was to evaluate the role of orthotopic injection in establishing a model of esophageal cancer using a human green fluorescent protein (GFP) cell line of human esophageal carcinoma. MATERIALS AND METHODS Nude mice were orthotopically injected in ...

OBJECTIVES Orthotopic diversion, initially performed solely in men, has now become a viable option in women. Approximately 15 yr ago, at several centres, urethra-sparing cystectomy and orthotopic diversion were initiated in women with bladder cancer. Several studies have since addressed both the oncologic and functional outcomes of this procedure. METHODS We describe our surgical technique of...

Although orthotopic xenografts offer the potential for improved modeling of tumor development and response to therapy, noninvasive methods are not readily available to serially monitor tumors growing at internal sites in small rodents. In this study, magnetic resonance (MR) imaging techniques were developed using a clinical 1. 5 T whole body scanner to routinely monitor tumor growth kinetics of...

Human cancer and response to therapy is better represented in orthotopic animal models. This paper describes the development of an orthotopic mouse model of ovarian cancer, treatment of cancer via oral delivery of drugs, and monitoring of tumor cell behavior in response to drug treatment in real time using in vivo imaging system. In this orthotopic model, ovarian tumor cells expressing lucifera...

CONTEXT Orthotopic liver transplantation is an excellent treatment approach for hepatocellular carcinoma in well-selected candidates. Nowadays some institutions tend to Expand the Milan Criteria including tumor with more than 5 cm and also associate with multiple tumors none larger than 3 cm in order to benefit more patients with the orthotopic liver transplantation. METHODS The data collecte...

We present an interesting intracardiac electrogram of a dissimilar atrial rhythm in a patient of bi-atrial orthotopic cardiac transplant.

Several types of animal models of human thyroid carcinomas have been established, including subcutaneous xenograft and orthotopic implantation of cancer cells into immunodeficient mice. Subcutaneous xenograft models have been valuable for preclinical screening and evaluation of new therapeutic treatments. There are a number of advantages to using a subcutaneous model; 1) rapid, 2) reproducible,...

PURPOSE Tumor host microenvironment plays an important role in tumor growth, metastasis, and response to cancer therapy. In this study, the influence of tumor host environment on tumor pathophysiology, photosensitizer distribution, and photodynamic therapy (PDT) treatment effect was examined in the metastatic at lymph node and lung (MatLyLu) rat prostate tumor. EXPERIMENTAL DESIGN MatLyLu tum...
