Abstract
Background and Aims:
Synchronous cancers (SC) are well known (2–11%) in patients with colorectal carcinoma (CRC). One study has shown that intraoperative palpation can miss up to 69% of the SC while other studies have shown altered planned surgical procedure due to preoperatively diagnosed synchronous lesions in 11–44%. The purpose of this study was to review all patients having surgery for CRC in our department since 2001, and to evaluate the extent of the perioperative colonic evaluation.
Materials and Methods:
The records of all patients operated for CRC between Jan. 2001 and Dec. 2007 in our department were reviewed. Only patients with CRC were included. Information regarding pre-, per- and postoperative colonic evaluation were obtained and occurrences of SC were evaluated.
Results:
Of the 534 patients included 124 (23%) patients had an impassable stenosis. Full preoperative colonic evaluation (FPCE) were done in 305 (26%) patients without stenosis. In 36 patients 39 SC were diagnosed. Seven SC were diagnosed postoperatively, of which five patients never had a FPCE. Three of these five patients had an inoperable SC, one patient died due to anastomosis leakage following re-operation and one patient had pulmonary embolism as a complication to re-operation.
Conclusions:
The results show that many patients (78%) never underwent FPCE, but also that many of these patients never had a full postoperative colonic evaluation. SC being overlooked can lead to increased morbidity and the possibility of advanced staging of the cancer which is also exemplified in this study.
