“…Surprisingly, other paper report completely opposite data, no finding endoscopic errors when the tumors are located in the descending (18) or the sigmoid colon (2). Finally, the comment that, as in our series, a high number of endoscopic errors has been reported for cecal CRC (12). In this anatomical segment, tumors can be large and make difficult ileocecal valve visualization.…”

“…According to the literature, endoscopic accuracy for a correct localization of CRC shows controversial results, with a range of a wrong localization between 4 and 34% (1,2,5,9,(12)(13)(14)(15)(16)(17). Besides this wide range regarding wrong endoscopic localization, it is remarkable the lack of papers analysing possible factors which can lead to a mistaken localization (9).…”

“…Besides this wide range regarding wrong endoscopic localization, it is remarkable the lack of papers analysing possible factors which can lead to a mistaken localization (9). It is also notorious the lack of agreement concerning the anatomic colonic segments where errors are more frequent (12,14,15,18).…”

Introduction: accurate preoperative localization of colorectal cancer (CRC) is very important, with a wide range of published error rates.Aims: to determine accuracy of endoscopic localization of CRC in comparison with preoperative computed tomography (CT). To analyse variables that could be associated with a wrong endoscopic localization.Patients and methods: endoscopic and CT localization of a series of CRC without previous surgery were reviewed. We studied the concordance between endoscopic and radiologic localization against operative findings comparing accuracy of endoscopy and CT. We analysed the frequency of wrong endoscopic diagnoses with regard to a series of patient, endoscopy and tumor variables.Results: two hundred thirty seven CRC in 223 patients were studied. Concordance with surgical localization was: colonoscopy = 0.87 and CT = 0.69. Endoscopic localization accuracy was: 91.1%; CT: 76.2%: p = 0.00001; OR = 3.22 (1.82-5.72). Obstructive cancer presented a higher rate of wrong localization: 18 vs. 5.7% in non-obstructive tumors (p = 0.0034; OR = 3.65 (1.35-9.96). Endoscopic localization mistakes varied depending on tumor location, being more frequent in descending colon: 36.3%, p = 0.014; p = 0.007;.Conclusions: endoscopic accuracy for CRC localization was very high and significantly better than CT accuracy. Obstructive tumor and those located in the descending colon or cecum were associated with a significant increase of the error risk of CRC endoscopic localization.

“…This rate exceeds others reported in the literature (11%-21%). [4][5][6] Our higher inac curacy may be explained by our categorical distinction of the hepatic flexure, ascending colon and cecum as different segments rather than including them all as the right colon. Also, we excluded distal rectal lesions that are accurately localized preoperatively by digital rectal examination and rigid sigmoidoscopy.…”

“…However, even colonoscopic tumour localization is inaccurate in 11.3%-21% of cases. [4][5][6] As such, colonoscopic tattooing is now considered to be stan dard practice for tumour localization before laparoscopic colorectal excision. 7,8 Several medical and surgical associa tions and societies recommend tattooing of suspicious looking lesions without reference to their size.…”

Background: Because small colonic tumours may not be visualized or palpated during laparoscopy, location of the lesion must be identified before surgery. The aim of this study was to evaluate the effectiveness of the current recommendation of endoscopic tattooing of lesions prior to laparoscopic colonic resections.Methods: All consecutive patients who underwent elective laparoscopic resection for a colonic lesion at a single tertiary institution between 2013 and 2015 were identified for chart review. Results:In total, 224 patients underwent laparoscopic resection for a benign or malignant colonic lesion during the study period. All patients had a complete colon oscopy preoperatively. In all, 148 patients (66%) had their lesion tattooed at endos copy. Most lesions were tattooed distally, but 15% were tattooed either proximally, both proximally and distally, or tattooed without specifying location as proximal or distal. Tattoo localization was accurate in 69% of cases. Tattooed lesions were not visible during surgery 21.5% of time; 2 cases were converted to open surgery to identify the lesion. Inaccuracy in endoscopic localization led to change in surgical plan in 16% of surgeries. In the nontattooed group, 1 case was converted to open surgery to localize the lesion, 3 required intraoperative colonoscopy and 1 had posi tive margins on final pathology. Conclusion:To improve surgical planning, we recommend the practice of endo scopic tattooing of all colon lesions at a location just distal to the lesion using multiple injections to cover the circumference of the bowel wall.Contexte : Comme il n'est pas toujours possible de voir ou de palper les petites tumeurs du côlon durant la laparoscopie, le siège de la lésion doit être localisé avant la chirurgie. Le but de cette étude était d'évaluer l'efficacité de la recommandation actuelle, qui consiste à tatouer les lésions au cours de l'endoscopie, avant les colec tomies laparoscopiques.Méthodes : Nous avons recensé tous les patients consécutifs ayant subi une résection laparoscopique non urgente d'une lésion du côlon dans un même établissement de soins tertiaires entre 2013 et 2015 afin d'analyser leurs dossiers.Résultats : En tout, 224 patients ont subi la résection laparoscopique d'une lésion bénigne ou maligne du côlon durant la période visée. Tous les patients ont passé une coloscopie totale avant la chirurgie. Le tatouage endoscopique de la lésion a été effec tué pour 148 patients (66 %). La plupart des lésions ont été tatouées au point distal, mais 15 % l'ont été soit au point proximal, soit au point proximal et au point distal, soit sans précision quant à l'emplacement. La localisation par tatouage était exacte dans 69 % des cas. Les lésions tatouées n'étaient pas visibles durant la chirurgie dans 21,5 % des cas; 2 cas ont été convertis en chirurgies effractives afin qu'on puisse repérer la lésion. L'inexactitude de la localisation endoscopique a entraîné la modification du plan chirurgical dans 16 % des chirurgies. Dans le groupe non tatoué, 1 cas a été converti ...
