Exploration of the medial border for laparoscopic D3 lymph node dissection in right hemi-colon cancer: a systematic review and meta-analysis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: The optimal medial boundary for lymph node dissection during laparoscopic radical right hemicolectomy for colorectal cancer remains uncertain. We investigated whether the superior mesenteric artery (SMA) or superior mesenteric vein (SMV) should serve as the medial border for D3 lymph node dissection in right hemicolon cancer. Methods: We systematically searched the Cochrane Library, EMBASE, CNKI, VIP, Wanfang, ClinicalTrials.gov, and SinoMed databases through March 2024. Studies comparing SMA- and SMV-based medial borders were included according to predefined criteria. Outcomes analyzed included intraoperative parameters, postoperative recovery, lymph node yield, complications, and survival. Results: Compared with the SMV group, the SMA group had more lymph nodes cleared ( Discussion: Using the SMA's left border for laparoscopic D3 dissection is safe and feasible, providing higher lymph node yield without increasing major complications. However, this greater yield did not translate into improved short-term survival. The long-term prognostic effect of the SMA approach requires further investigation.
