Abstract
Aim. This study aimed to assess the impact of routine histological examination of stapled colorectal anastomotic doughnuts in patients undergoing rectal cancer surgery (RCS). Justification of biopsy examination could form part of the strategies of NHS net zero practice with effort to reduce wastage and carbon footprint.
Method. A data analysis of all patients undergoing RCS during 2019–2021 at our institute was performed. We also analysed the cost of preparing and reviewing histology slides.
Results. 52 patients underwent anterior resection during the aforementioned period. Doughnuts were sent in 37 (71%) patients. 23 (62%) patients were male, and 14 (38%) were female. The median age at diagnosis was 68 (range 54–84) years. All resected specimens were adenocarcinomas. Of the 37 patients, 18 (49%) underwent low anterior resection and 19 (51%) underwent high anterior resection. Proximal doughnuts were sent in 26 (70%) patients, whereas distal doughnuts were sent in all cases. Mean distal microscopic resection margin from tumour was 22 mm (range 6–45 mm). Each doughnut required 3 slides, each costing £50 and requiring 82 minutes to fix and read. This incurred a cost of £13,650 and required 19,656 hours of preparation time. All of the doughnuts as well as resection margins were negative for malignancy.
Conclusion. Routine histopathological examination of doughnuts is time and cost-intensive however provides little or no clinical value (particularly analysis of the proximal doughnut). Distal doughnuts should only be sent for histological examination in exceptional circumstances.
