Fluorescence angiography with indocyanine green for low anterior resection in patients with rectal cancer: a prospective before and after study.

Background: Inadequate bowel perfusion is among risk factors for colorectal anastomotic leaks. Perfusion can be assessed with indocyanine green fluorescence angiography (ICG) during colon resections. Possible benefits from its systematic use in high-risk patients with rectal cancer remain inconsistent.

TEMPOUR: A Randomized Controlled Trial Assessing Perioperative Use of An Alpha-1-Blocker to Reduce Postoperative Urinary Retention Following Transanal Endoscopic Microsurgery Procedures.

Background: Transanal endoscopic microsurgery is a treatment option for a wide range of rectal lesions. Postoperative urinary retention is a frequently associated complication. Some studies have suggested that the use of alpha-1-blockers may reduce the risk of postoperative urinary retention after hernia and colorectal surgery, but evidence is lacking.

New elements in the C-type natriuretic peptide signaling pathway inhibiting swine in vitro oocyte meiotic resumption.

C-type natriuretic peptide (CNP) and its cognate receptor, natriuretic peptide receptor (NPR) B, have been shown to promote cGMP production in granulosa/cumulus cells. Once transferred to the oocyte through the gap junctions, the cGMP inhibits oocyte meiotic resumption. CNP has been shown to bind another natriuretic receptor, NPR-C.
