Distribution of referred patients after coding. Referred patients were categorized using the following code: 1. Primary resection status: R0, R1, or R2. 2. Resection status after re-excision: R0, R1, or R2. 3. Presence or absence of tumor at re-excision: 0 = no tumor found; 1 = tumor found. Overall, residual tumor after re-excision was found in 53.13 % of cases. Of all the patients referred with histopathological information indicating complete tumor resection, half had residual tumor in the re-excision specimen. In 33 cases (46.5 %), the primary histopathological information on resection status was misleading and either overestimated or underestimated the resection margins (R1-R0-0; R2-R0-0; R0-R0-1). In 27 cases (38 %), revisional surgery ostensibly improved resection status (R1-R0-0; R2-R0-0). In 35 cases (49.3 %), there was a real improvement (R0-R0-1; R1-R0-1; R2-R0-1; R2-R1-1). In nine cases (12.7 %), our surgery did not improve the resection status (R0-R0-0; R1-R1-1)
