Proposal of a new visual analogue scale to describe the extent of lymphadenectomy in right-sided colectomy for cancer-a prospective observational study.
Background: Lymphadenectomy in right-sided colon cancer lacks standardized reporting. The aim was to develop a visual analogue scale (VAS) based on mesenteric vessels to describe the extent of lymphadenectomy.
Methods: We included patients undergoing surgery for right-sided colon cancer from January 2021 to September 2024. Data were collected via a web-based database. Immediately after surgery, surgeons recorded the VAS score, vascular visualization, and specimen quality.
Results: Data from 155 patients were analyzed. Median age was 74 (IQR: 68-80), with 53% female. The median VAS score was 8.2 (IQR: 7.8-8.9). The superior mesenteric vein (SMV) was visualized in 84% of cases, with a median VAS score of 8.4 (IQR: 8.0-9.2) for visualized and 7.0 (IQR: 6.8-7.5) for non-visualized (p < 0.001). The gastrocolic trunk of Henle (GTH) was visualized in 51%, with a median VAS score of 8.7 (IQR: 8.3-9.7) for visualized and 7.9 (IQR: 7.3-8.0) for non-visualized (p < 0.001). Specimen quality was Type 0 (best) in 54% (VAS score 8.6, IQR: 8.2-9.5), Type I in 37% (VAS score 7.9, IQR: 7.3-8.0), and Type II in 6% (VAS score 6.9, IQR: 6.5-7.9; p < 0.001). A positive correlation between VAS score and lymph node count was found (r = 0.43, p < 0.001).
Conclusions: The VAS score is a reliable and feasible method to describe lymphadenectomy in right-sided colon cancer. Unlike categorical classifications, the VAS score is based on anatomical landmarks and does not depend on consensus definitions. It reflects the visualization of vascular structures and correlates with specimen quality and lymph node yield.

期刊介绍：
Techniques in Coloproctology is an international journal fully devoted to diagnostic and operative procedures carried out in the management of colorectal diseases. Imaging, clinical physiology, laparoscopy, open abdominal surgery and proctoperineology are the main topics covered by the journal. Reviews, original articles, technical notes and short communications with many detailed illustrations render this publication indispensable for coloproctologists and related specialists. Both surgeons and gastroenterologists are represented on the distinguished Editorial Board, together with pathologists, radiologists and basic scientists from all over the world. The journal is strongly recommended to those who wish to be updated on recent developments in the field, and improve the standards of their work.
Manuscripts submitted for publication must contain a statement to the effect that all human studies have been reviewed by the appropriate ethics committee and have therefore been performed in accordance with the ethical standards laid down in an appropriate version of the 1965 Declaration of Helsinki. It should also be stated clearly in the text that all persons gave their informed consent prior to their inclusion in the study. Details that might disclose the identity of the subjects under study should be omitted. Reports of animal experiments must state that the Principles of Laboratory Animal Care (NIH publication no. 86-23 revised 1985) were followed as were applicable national laws (e.g. the current version of the German Law on the Protection of Animals). The Editor-in-Chief reserves the right to reject manuscripts that do not comply with the above-mentioned requirements. Authors will be held responsible for false statements or for failure to fulfill such requirements.
