Background
Adequate lymph nodes retrieval is important in colorectal cancer staging for the selection of patients that necessitate adjuvant treatments. The length of bowel resected has been associated with the number of nodes retrieved. We have reviewed our specimens to find out high-risk operations for inadequate nodal sampling and estimate the minimum length of bowel to resect to achieve this purpose.

Material and Methods
Retrospective review of colorectal specimens over 10 years of activity. Data such as location of the tumour, type of operation performed, length of bowel resected and number of lymph nodes retrieved were gathered.

Result
Abdominoperineal and Hartmann's resections produced significant lower adequate retrievals compared to other colorectal operations, corresponding to 45.4% and 59.1% of cases respectively. The measured average length of bowel was 30 cm and 25 cm respectively. Increasing the length to 36 cm and 42 cm would increase the adequacy rate to 90%.

Conclusion
Abdominoperineal and Hartmann's resections are in our series high-risk operations that frequently do not produce the minimum number of lymph nodes for adequate nodal staging and may require additional manoeuvres such as mobilization of the splenic flexure to achieve the minimum length of bowel to resect.
