Modification of the lund‐kennedy endoscopic scoring system improves its reliability and correlation with patient‐reported outcome measures

Modification of the LK system by excluding the subscores of scarring and crusting improves its reliability and its correlation with PROMs. In addition, the MLK system retains the familiarity of the widely used LK system and is applicable to any patient irrespective of surgical status. The MLK system may be a more suitable and reliable endoscopic scoring system for clinical practice and outcomes research.
