Mesocolic plane surgery with central vascular ligation produces an oncologically superior specimen following colon cancer resection and appears to be related to optimal outcomes. We aimed to assess whether a regional educational programme in optimal mesocolic surgery led to an improvement in the quality of specimens.
Following an educational programme in the Capital and Zealand areas of Denmark, 686 cases of primary colon cancer resected across six hospitals were assessed by grading the plane of surgery and undertaking tissue morphometry. These were compared to 263 specimens resected prior to the educational programme.
Across the region, the mesocolic plane rate improved from 58% to 77% (P < 0.001). One hospital had previously implemented optimal surgery as standard prior to the educational programme and continued to produce a high rate of mesocolic plane specimens (68%) with a greater distance between the tumour and the high tie (median for all fresh cases: 113 vs 82 mm) and lymph node yield (33 vs 18) compared to the other hospitals. Three of the other hospitals showed a significant improvement in the plane of surgical resection.
A multidisciplinary regional educational programme in optimal mesocolic surgery improved the oncological quality of colon cancer specimens as assessed by mesocolic planes; however, there was no significant effect on the amount of tissue resected centrally. Surgeons who attempt central vascular ligation continue to produce more radical specimens suggesting that such educational programmes alone are not sufficient to increase the amount of tissue resected around the tumour.
结肠癌切除术后,中血管结扎的系膜平面外科手术可产生具有更高肿瘤学优势的标本,且似乎与更优的结果相关。我们旨在评估在中肠系膜外科手术方面的区域性教育计划是否可改善标本质量。
在丹麦首都地区和西兰地区实施教育计划后,评估了 6 家医院的 686 例原发性结肠癌切除病例,通过对手术平面分级和进行组织形态计量学来评估。将这些结果与教育计划之前切除的 263 个标本进行比较。
在整个地区,中肠系膜平面率从 58%提高到 77%(P<0.001)。有 1 家医院在教育计划之前已将优化手术作为标准,继续产生高比例的中肠系膜平面标本(68%),肿瘤与高位结扎之间的距离更大(所有新鲜病例的中位数:113 比 82mm),且淋巴结产量更高(33 比 18),与其他医院相比。其他 3 家医院的手术切除平面有显著改善。
在优化的中肠系膜外科手术方面,多学科区域性教育计划提高了结肠癌标本的肿瘤学质量,可通过中肠系膜平面评估;然而,对中央组织切除量没有显著影响。尝试中央血管结扎的外科医生继续产生更激进的标本,这表明仅此类教育计划不足以增加肿瘤周围的组织切除量。
