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

backgroundTo compare perioperative and short-term oncologic outcomes of laparoscopic pancreaticoduodenectomy (LPD) to open pancreaticoduodenectomy (OPD) using data from large-scale retrospective cohorts and randomized controlled trials (RCTs) in the last 10 years.

methodsA meta-analysis to assess the safety and feasibility of LDP and OPD registered with PROSPERO: (CRD42020218080) was performed according to the PRISMA guidelines. Studies comparing LPD with OPD published between January 2010 and October 2020 were included; only clinical studies reporting more than 30 cases for each operation were included. Two authors performed data extraction and quality assessment independently. The primary endpoint was operative times, blood loss, and 90 days mortality. Secondary endpoints included reoperation, length of hospital stay (LOS), morbidity, Clavien-Dindo ≥3 complications, postoperative pancreatic fistula (POPF), blood transfusion, delayed gastric emptying (DGE), postpancreatectomy hemorrhage (PPH), and oncologic outcomes (R0-resection, lymph node dissection).

resultsOverall, the final analysis included 15 retrospective cohorts and 3 RCTs comprising 12,495 patients (2,037 and 10,458 patients underwent LPD and OPD). It seems OPD has more lymph nodes harvested but no significant differences [weighted mean difference (WMD): 1.08; 95% confidence interval (CI): 0.02 to 2.14; P=0.05]. Nevertheless, compared with OPD, LPD was associated with a higher R0 resection rate [odds ratio (OR): 1.26; 95% CI: 1.10-1.44; P=0.0008] and longer operative time (WMD: 89.80 min; 95% CI: 63.75-115.84; P<0.00001), patients might benefit from lower rate of wound infection (OR: 0.36; 95% CI: 0.33-0.59; P<0.0001), much less blood loss (WMD: -212.25 mL; 95% CI: -286.15 to -138.14; P<0.00001) and lower blood transfusion rate (OR: 0.58; 95% CI: 0.43-0.77; P=0.0002) and shorter LOS (WMD: -1.63 day; 95% CI: -2.73 to -0.51; P=0.004). No significant differences in 90-day mortality, overall morbidity, Clavien-Dindo ≥3 complications, reoperation, POPF, DGE and PPH between LPD and OPD.

conclusionsOur study suggests that after learning curve, LPD is a safe and feasible alternative to OPD as it provides similar perioperative and acceptable oncological outcomes when compared with OPD.
