Routine pathology examination in the era of value-based healthcare: the case of haemorrhoids specimens

Routine pathologic examination of specimens is a common practice with ill-defined value. The present study is the first to investigate the incidence and cost of incidental microscopic lesions in both haemorrhoidectomy and stapled haemorrhoidopexy specimens. Pathological reports of specimens obtained from haemorrhoidectomy and stapled haemorrhoidopexy procedures performed from January 2003 to May 2017 were analysed. Specimens resulting from patients treated for any disease other than haemorrhoids alone were excluded from the study. Unexpected diagnoses in the pathological report were defined as incidental diagnoses. A cost analysis was then performed. In the considered period we performed a total of 3017 procedures complying with our criteria. We found 65 (2.15%) unexpected lesions. Of the incidental diagnosis, 30 (0.99%) altered either the follow-up or the treatment. The incidences of both findings were extremely higher in haemorrhoidectomies specimens (p < 0.0001). We estimated that the cost of 14 years of routine pathological examination of haemorrhoids specimens was 133,351.4 euros, each consequential incidental diagnosis costing 4445.03 euros. The incidence of unexpected lesions in routine pathologic examination of haemorrhoidectomy and haemorrhoidopexy specimens is low but not negligible. The vast majority of incidental findings were found among haemorrhoidectomy specimens. Even though the real value of routine pathological examination of haemorrhoids specimens is still uncertain, from a clinical standpoint we were glad to suggest each patients the best follow-up and/or treatment. Future studies should assess preoperative patient’s risk stratification and careful intraoperative macroscopic inspection strategies for selective pathology examination of haemorrhoids specimens.
