Better function with a colonic J-pouch or a side-to-end anastomosis? A randomized controlled trial to compare the complications, functional outcome, and quality of life in patients with low rectal cancer after a J-pouch or a side-to-end anastomosis. Ann Surg 2019; 269: 815-826.

Published: 2nd August 2019

Authors: Parc Y, Ruppert R, Fuerst A, Golcher H, Zutshi M, Hull T et al.

Conclusion

A total of 19% of patients had complications, with similar rates after both procedures in this study that included 190 procedures. All functional outcomes were also comparable after two years.
