Laparoscopic Minor Liver Resections for Hepatocellular Carcinoma in the Posterosuperior Segments Using the Rubber Band Technique.
Article in World journal of surgery, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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
backgroundAlthough laparoscopic minor liver resections (LLR) of posterosuperior (PS) segments are technically challenging, several expert centers are increasingly performing this procedure. In the present study, we introduced novel techniques, including the rubber band traction method and positional changes, and compared surgical outcomes of LLR for hepatocellular carcinoma (HCC) located in PS segments with open minor liver resection (OLR).
methodsFrom January 2008 to August 2019, 113 patients underwent laparoscopic (n = 55) or open (n = 58) minor liver resections for single small HCCs (<5 cm) located in PS segments. Propensity score matching in a 1:1 ratio was conducted to minimize preoperative selection bias, and surgical outcomes were compared between the two groups.
resultsThere was no intraoperative mortality or reoperation in either group. One conversion to open surgery was necessary due to severe post-operative adhesions. The matched LLR group compared to OLR had significantly shorter operative time (215.16 vs. 251.41 min, P = 0.025), lesser blood loss (218.11 vs. 358.92 mL, P = 0.046), lower complication rate (8.1% vs. 29.7%, P = 0.018), and shorter hospital stay (7.03 vs. 11.78 days, P = 0.001). Intraoperative transfusion, R0 resection, resection margin, 5-year disease-free survival and 5-year overall survival were comparable.
conclusionOur standardized LLR provided improved short-term outcomes and similar long-term outcomes, when compared with OLR. With advanced techniques and accumulated surgical experience, LLR can be the first option for HCC in PS segments at expert centers.
