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

backgroundThe choice of surgical strategy for patients with proximal gastric cancer is controversial. The purpose of this study was to assess the feasibility, safety, and surgical and functional outcomes of laparoscopy-assisted proximal gastrectomy (LAPG) and laparoscopy-assisted total gastrectomy (LATG).

methodsBetween June 2003 and December 2009, 131 patients with proximal gastric cancer underwent LAPG (n = 50) or LATG (n = 81) at Seoul National University Bundang Hospital. We reviewed their medical and surgical records from our prospectively collected gastric cancer database. The clinicopathologic characteristics and short-term, long-term, and functional outcomes were compared between the 2 groups.

resultsThere were no significant differences in demographics, T-stage, N-stage, or survival between the 2 groups. The LAPG group had a shorter operative time and lower estimated blood loss than the LATG group. The early complication rates after the LAPG and LATG procedures were 24.0 and 17.3%, respectively (p = 0.349). The incidence of reflux symptoms was significantly higher in the LAPG group (32.0 vs. 3.7%, p < 0.001). The parameters that reflected nutritional status were similar in the 2 groups.

conclusionLAPG is a feasible and acceptable method for treating proximal early gastric cancer in terms of surgical and oncologic safety. However, esophagogastrostomy after LAPG was associated with an increased risk of reflux symptoms. Antireflux procedures should be considered to prevent reflux symptoms after LAPG.
