Description of intervention(s) / exposure
This is a retrospective cohort study of patients who received haemorrhoidectomies at Hervey Bay Hospital between March 2012 and May 2020. The proportion sent for histology is determined by consulting the medical records. The histology results of those shows the proportion of haemorrhoidectomy specimens showing incidental anal cancers. Cost effectiveness of routine histology was investigated by weighing the number of incidental anal cancers detected against the cost of analysis.

Outcomes
Primary outcome [1] 328277 0
Cost of histological analysis per case of incidental anal cancer. This will be done by accessing medical records of all patients receiving haemorrhoidectomy to determine histological diagnosis, and comparing to the cost of histological analysis as stated by the pathology provider.

Summary
Brief summary
This study aimed to determine the cost-effectiveness of routine histology for haemorrhoidectomy specimens in a regional Australian hospital, as a way of detecting incidental anal cancer. The secondary aim was to determine the proportion of specimens that were sent for histology over the study period and whether individual surgeons had a significant preference for whether to send for histology.
