Impact of Laparoscopic Converted to Open Gastrectomy on Short- and Long-Term Outcomes of Patients with Locally Advanced Gastric Cancer: A Propensity Score-Matched Analysis.
Article in Journal of gastrointestinal surgery : official journal of the Society for Surgery of the Alimentary Tract, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundIt remains unclear whether laparoscopic conversation to open gastrectomy causes higher morbidity and has an adverse effect on the long-term survival outcomes of patients with gastric cancer. This study was designed to evaluate the impact of the conversion on short and long-term outcomes of patients with locally advanced gastric cancer (AGC).
methodsWe retrospectively investigated 871 patients who initially underwent laparoscopic gastrectomy (LG) for pathologically confirmed diagnosis of AGC between February 2009 and April 2018. The patients were grouped as the conversion (CONV) group and completed laparoscopic (LAP) group. The 1:2 propensity score matching was performed to reduce the effect of bias due to the imbalanced baseline features between the two groups. Multivariate analyses were performed to identify risk factors for conversion and poor survival.
resultsAfter propensity-score matching, 168 patients (56 in the CONV group and 112 in the LAP group) were studied. The CONV group was associated with significantly longer operation time (252.4 vs. 216.7 min, P < 0.001) and greater estimated blood loss (234.8 vs. 171.2 ml, P < 0.001) as compared with the LAP group. The time to first flatus (3.8 vs. 3.3 days, P = 0.043), time to start a liquid diet (4.1 vs. 3.5 days, P = 0.021), and postoperative hospital stay (8.7 vs. 7.6 days, P = 0.020) were significantly longer in the CONV group than that in the LAP group. The overall complication rate did not differ significantly between the CONV group and the LAP group (16.1% vs. 12.5%, P = 0.692). Both 5-year overall survival (OS) and 5-year disease-free survival (DFS) did not differ significantly between the CONV group and the LAP group (P = 0.805, P = 0.945, respectively). Multivariate analysis showed that lymphovascular invasion and stage III were independent prognostic factors for poor OS and DFS, whereas conversion was not.
conclusionsThe conversion from laparoscopic to open gastrectomy had no negative impact on morbidity and long-term survival outcomes for patients with locally AGC.
