Early and Late Trocar-Site Outcomes After Laparoscopic Sleeve Gastrectomy Using a Standardized Fascial Closure Technique: a Prospective Observational Study.
Observational study in Obesity surgery, 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
backgroundTrocar-site complications after laparoscopic metabolic bariatric surgery are uncommon but may result in clinically relevant morbidity. Standardized fascial closure of trocar sites, particularly in patients with obesity, has been proposed as a strategy to minimize early and late postoperative complications.
objectiveTo describe early and late clinically assessed trocar-site outcomes following laparoscopic sleeve gastrectomy in a consecutive cohort managed with a standardized 12-mm fascial closure protocol.
methodsA prospective observational study was conducted. Consecutive adult patients undergoing laparoscopic sleeve gastrectomy between February 2023 and August 2024 were enrolled. Fascial closure of the 12-mm trocar site was performed using a standardized institutional technique. Clinical follow-up was conducted at 6, 12, and 18 months. Early outcomes included trocar-site pain, infection, seroma, hematoma, and bleeding. Late outcomes included chronic pain, trocar-site hernia, and neuralgia. Descriptive statistical analyses were performed.
resultsA total of 125 patients were enrolled, of whom 118 completed the 18-month follow-up and were included in the analysis. Mean age was 42.4 ± 11.9 years, and mean body mass index was 38.6 ± 5.3 kg/m². Early postoperative complications were infrequent. Trocar-site pain was reported in four patients (3.4%) and was predominantly mild in severity. No cases of infection, seroma, hematoma, or bleeding were observed. During follow-up, no clinically detected late trocar-site complications, including trocar-site hernia, chronic pain, or neuralgia, were identified.
conclusionIn this prospective single-center observational cohort, clinically assessed early trocar-site events were infrequent, and no clinically detected late trocar-site events were observed through 18 months of follow-up. These findings are descriptive and hypothesis-generating; comparative studies are required to determine whether standardized closure techniques or specific devices confer benefit over alternative strategies.
