Scoring systems as outcomes assessment of the treatments for haemorrhoidal disease: a systematic review of the literature

Purpose The comparison between haemorrhoidal treatments is still unclear. Attempts have been made to adopt a unifying postoperative scoring system and thus ensure adequate comparison between clinical trials. We aimed to systematically review the available outcome scores of haemorrhoidal treatment. Methods MEDLINE/Pubmed, Web of science, Embase and Cochrane were searched from database implementation until the December 6th 2019. All studies describing or referencing a score to assess haemorrhoidal disease treatment were included. Likert scale alone, incontinence score alone, general assessment of quality of life or scores developed for other proctologic disorders were excluded. The main outcome measures were validation of the scores and correlation of the score items to the core outcome set for haemorrhoidal disease developed by the European Society of Coloproctology. Results From the 633 records initially screened, 22 studies were included: 8 original articles describing a scoring system and 14 referencing a previously described scoring system. Only 1 score was validated by an external prospective cohort. All the scores evaluated the symptoms of haemorrhoidal disease. No score integrated the disease recurrences or patient's satisfaction. Scores values tended to decrease postoperatively. Conclusions The scores described by Gerjy et al. and by Shanmugan et al. are available questionnaires, which have been validated and used in various studies. These scores might help researchers for comparative studies between treatment modalities and optimize haemorrhoids treatment.
