Quantitative evaluation of anastomotic perfusion during colorectal surgery via indocyanine green fluorescence angiography: a narrative review.

Background And Objective: Quantitative studies of indocyanine green (ICG) are needed to optimize its evaluative potential in anastomotic perfusion during colorectal surgery. However, some limitations still existed in current studies about qualitative evaluations such as small-scale studies, the inconsistent concentration of the drug, the method of injection, etc. Therefore, this review summarized the primary quantitative parameters, image, method, and so on, during ICG fluorescence angiography aiming to further provide a theoretical basis for the application of ICG in laparoscopic colorectal surgery.

Study on the relationship between sex hormone changes and erectile dysfunction in patients with chronic prostatitis/chronic pelvic pain syndrome.

Background: To investigate the relationship between serum sex hormones and erectile dysfunction (ED), changes in erectile function and sex hormones were studied in patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS).

Methods: A total of 171 patients with CP/CPPS who met the inclusion criteria from January 2016 to June 2019 were retrospectively analyzed. The level of patient's testosterone (TT), estradiol (E2), luteinizing hormone (LH), follicle stimulating hormone (FSH), prolactin (PRL), premature ejaculation diagnostic tool (PEDT) score and international index of erectile function (IIEF-5) score were separately observed and compared.

Role of lymph node dissection in radical cystectomy.

The number of lymph node dissections (LNDs) is an independent factor influencing the survival time of patients with bladder cancer (BCa) after radical resection (RC). The present study aimed to investigate the association between the number of LNDs and the survival of patients with BCa at different stages and who underwent RC in the United States of America and China. Records from 17,730 American patients with BCa and 158 Chinese patients with BCa were collected from the Surveillance, Epidemiology and End Results (SEER) and the Shanghai Tenth People's Hospital (China) databases, respectively.
