Efficacy of inferior vesical vessels preservation in lateral lymph node dissection for rectal cancer: Short- and long-term outcomes.

Aim: Lateral lymph node dissection (LLD) is performed for rectal cancer, with some cases requiring resection of the inferior vesical vessels (IVV). However, whether preservation or resection of the IVV affects urinary dysfunction (UD) as a major complication or local recurrence (LR) is unclear. Thus, we assessed the effect of IVV resection on the short- and long-term outcomes of rectal cancer.

Modified oral antibiotics and mechanical bowel preparation (OAMBP) versus conventional OAMBP for sigmoid colon and rectal surgery: A multicenter randomized non-inferiority trial.

Aim: To evaluate whether the use of a laxative with reduced patient burden in oral antibiotics and mechanical bowel preparation (OAMBP) could prevent surgical site infection (SSI) in left-sided colon and rectal cancers.

Methods: This multicenter, non-blinded, randomized, non-inferiority trial included patients who underwent elective colorectal surgery for colorectal cancer in a university and community hospital in Japan from April 1, 2021 to March 31, 2023. We compared conventional OAMBP (polyethylene glycol, metronidazole, and kanamycin) (cOAMBP group) with modified OAMBP (sodium picosulfate hydrate, metronidazole, and kanamycin) (mOAMBP group).
