The fate and significance of retained staples after stapled haemorrhoidopexy.

We studied the fate of staples after stapled haemorrhoidectomy (SH) and reviewed the complications they may cause. A survey was carried among 16 surgeons experienced at performing SH to assess their knowledge regarding retained staples. In addition, plain pelvic radiology was used to visualize residual staples at different time intervals after SH in 45 patients. Ten (63%) surgeons informed their patients that the staples would be shed within 3 months of SH. Regardless of the timing of surgery, part of the staple line was radiologically visible in all patients, and in 19 patients (45%) the staple line was completely visible. Contrary to the common belief, the majority of staples are retained after SH. [ABSTRACT FROM AUTHOR]
