Association between the valveless Airseal
Article in Surgical endoscopy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThe AirSeal
methodsWe retrospectively analyzed 142 consecutive patients who underwent MIPD between May 2021 and January 2026. Patients were divided into an ASIS group and a standard insufflation system (StIS) group. In both groups, pneumoperitoneum pressure was maintained at 10 mmHg. The primary outcome was VTE, including deep vein thrombosis (DVT) and pulmonary embolism (PE), occurring within 14 days after surgery.
resultsAmong 142 patients, 48 underwent MIPD with ASIS and 94 with StIS. VTE occurred in 12 patients (8.5%) and was significantly more frequent in the ASIS group (16.7% vs. 4.3%, p = 0.012). VTE tended to occur earlier in the ASIS group (median 2.5 vs. 7 days, p = 0.064). Five patients in the ASIS group developed PE including four symptomatic cases, whereas all VTE events in the StIS group were asymptomatic. Multivariable analysis identified ASIS use (odds ratio [OR] 5.67, 95% confidence interval [CI] 1.26-33.2) and open conversion (OR 6.42, 95% CI 1.59-26.6) as independent risk factors for VTE.
conclusionsASIS use at a pneumoperitoneum pressure of 10 mmHg was independently associated with an increased risk of early postoperative VTE after MIPD. Further investigation of lower-pressure or intermittent desufflation strategies is warranted.
