Effect of glyceryl trinitrate ointment on pain control after hemorrhoidectomy: a meta-analysis of randomized controlled trials. World J Surg 2016; 40: 215-224.

Published: 4th February 2016

Authors: Liu J-W, Lin C-C, Kiu K-T, Wang C-Y, Tam K-W

Conclusion

There were twelve trials consisting of 1095 haemorroidectomy procedures. Postoperative pain was significantly reduced on days 1, 3, 7 and 14 by GTN ointment. It also speeded return to normal activity and improved wound healing at three weeks.
