A multidisciplinary analysis of 8-mm port-site hernias in 2,337 robotic ports and the realities of its risk factors.
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
backgroundPort-site hernia (PSH) at 8-mm robotic trocar sites is considered uncommon, and routine fascial closure is generally not recommended. However, clinically significant PSH continues to occur, and its underlying mechanisms remain incompletely understood. This study aimed to evaluate the incidence and risk factors of 8-mm PSH after robotic-assisted surgery and to explore practical preventive strategies.
methodsWe retrospectively analyzed 816 patients who underwent robotic-assisted surgery across the gastrointestinal, hepatobiliary-pancreatic, urological, and gynecological specialties between January 2020 and December 2024. A total of 2337 8-mm ports were included, all of which were left without fascial closure. Patient characteristics, port locations, drain placement and size, operative times, and perioperative factors were evaluated in patients who developed PSH.
resultsThe median BMI of the overall cohort was 22.9 kg/m
conclusionsEight-millimeter PSH is a rare but potentially preventable complication of robotic-assisted surgery. The risk appears to be concentrated in non-obese patients with lateral abdominal wall ports, particularly when these sites are used for drain placement. Intraoperative digital assessment of the fascial defect using the "pinky test" may facilitate selective fascial closure of high-risk port sites and help reduce the occurrence of this complication.
