Randomized Controlled Trial
Comparison of pathological outcomes after transanal versus laparoscopic total mesorectal excision: a prospective study using data from randomized control trial.
Total mesorectal excision (TME) is the standard procedure for middle lower rectal cancer, and transanal total mesorectal excision (taTME) was founded as a valid alternative to the open and laparoscopic TME. The quality of the procedure performed is important for prognosis of patients. This study was designed to compare the pathological results of taTME with those of laparoscopic TME (laTME), based on the data from a randomized control trial (RCT: NCT02966483). ⋯ The pathological outcomes between transanal and laparoscopic total mesorectal excision are similar. The rate of positive resection margin could not be significant decreased, nonetheless the decrease trend could be shown.

Randomized Controlled Trial
Effects of quadratus lumborum block regional anesthesia on postoperative pain after colorectal resection: a randomized controlled trial.
Postoperative pain following colorectal surgery is associated with a significant use of opioids. Recently, regional anesthesia, such as the posterior quadratus lumborum block (QL2), has been proposed to improve pain relief and reduce opioid use. However, the benefit of the QL2 on postoperative pain control remains controversial. ⋯ We did not observe a reduction in postoperative opioid administration at 24 h with a posterior quadratus lumborum block regional anesthesia in patients undergoing elective colorectal surgery.
