Documented complications of staple hemorrhoidopexy: a systematic review

A systematic review addressing reported complications of stapled hemorrhoidopexy was conducted. Articles were identified via searching OVID and MEDLINE between July 2011 and October 2013. Limitations were placed on the search criteria with articles published from 1998 to 2013 being included in this review. No language restrictions were placed on the search, however foreign language articles were not translated. Two reviewers independently screened the abstracts for relevance and their suitability for inclusion. Data extraction was conducted by both reviewers and entered and analyzed in Microsoft Excel. The search identified 784 articles and 78 of these were suitable for inclusion in the review. A total of 14,232 patients underwent a stapled hemorrhoidopexy in this review. Overall complication rates of stapled hemorrhoidopexy ranged from 3.3%-81% with 5 mortalities documented. Early and late complications were defined individually with overall data suggesting that early complications ranged from 2.3%-58.9% and late complications ranged from 2.5%-80%. Complications unique to the procedure were identified and rates recorded. Both early and late complications unique to stapled hemorrhoidopexy were identified and assessed.
