Real Time Microscopic Imaging During Robot Assisted Prostate Cancer Surgery
Summary
The study involves use of a device called an endomicroscope to obtain high resolution images of microscopic structures during robot-assisted prostate cancer surgery. This feasibility study is largely descriptive, and will use endomicroscopy to document the cellular and architectural appearance of tissue during minimally invasive prostate surgery for later comparison with features seen upon conventional histopathological examination of biopsies or resection specimens.
Description
Prostate surgery requires meticulous dissection around nerves and associated structures such as the bladder, seminal vesicles and vas deferens. Nerve damage during prostatectomy can result in undesirable outcomes such as impotence and urinary incontinence. Robot assisted minimally invasive prostatectomy offers enhanced visualisation of the surgical field. Superior clinical outcomes in terms of length of hospital stay, blood loss, and oncologic margins compared with open surgery are reported. Confocal endomicroscopy provides high resolution subsurface cellular imaging in real time and is already in clinical use in gastroenterology and under investigation in other surgical applications. A potential role exists for confocal endomicroscopy to enhance microscopic nerve identification intra-operatively and guide surgical decision making during robot-assisted prostatectomy.

Medical and Biotech [MESH] Definitions
Prostate-specific Antigen
A glycoprotein that is a kallikrein-like serine proteinase and an esterase, produced by epithelial cells of both normal and malignant prostate tissue. It is an important marker for the diagnosis of prostate cancer.
Fenretinide
A synthetic retinoid that is used orally as a chemopreventive against prostate cancer and in women at risk of developing contralateral breast cancer. It is also effective as an antineoplastic agent.
Ultrasound, High-intensity Focused, Transrectal
Tissue ablation of the PROSTATE performed by ultrasound from a transducer placed in the RECTUM. The procedure is used to treat prostate cancer (PROSTATIC NEOPLASMS) and benign prostatic hypertrophy (PROSTATIC HYPERPLASIA).
Prostatic Secretory Proteins
Proteins secreted by the prostate gland. The major secretory proteins from the human prostate gland include PROSTATE-SPECIFIC ANTIGEN, prostate-specific acid phosphatase, prostate-specific membrane antigen, and prostate-specific protein-94.
Prostatic Neoplasms
Tumors or cancer of the PROSTATE.
