1 · What the graph read from it

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.

2 · The registry

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

backgroundSingle-port surgery offers improved cosmesis but is technically demanding. The da Vinci™ SP (DVSP) system aims to overcome these challenges; however, rigorous data on the comparison between the DVSP system and the standard multi-port da Vinci™ Xi system (DVXi) are scarce. This study aimed to compare the short-term outcomes of the DVSP with those of the DVXi for robotic distal gastrectomy after adjusting for patient selection bias.

methodsWe retrospectively reviewed 311 patients undergoing robotic distal gastrectomy for gastric cancer between March 2023 and December 2024 at two institutions. Based on patient demographics and tumor characteristics, a 1:1 propensity score matching analysis was performed to mitigate bias. After matching, 36 patients in the DVSP group were compared with 36 patients in the DVXi group. Perioperative outcomes, pathological findings, and postoperative complications were analyzed.

resultsThe DVSP group had significantly shorter median operative time (329 vs. 414 min, p < 0.001) and console time (261 vs. 332 min, p < 0.001). A significantly higher number of lymph nodes were retrieved in the DVSP group (mean 46 vs. 32, p = 0.04). The median postoperative stay exhibited a trend toward being shorter in the DVSP group (11 vs. 12 days, p = 0.08). No conversions to open or multi-port surgery occurred. The incidence of postoperative complications (Clavien-Dindo grade ≥ II) was comparable between the groups (8.3% vs. 16.7%, p = 0.48).

conclusionsIn this study, single-port gastrectomy using the DVSP system was safe and feasible in the short-term outcomes compared with multi-port gastrectomy using the DVXi system.
