Incidental Gastrointestinal Stromal Tumors (GIST) During Laparoscopic Sleeve Gastrectomy Procedures: a Retrospective Study.

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
purposeGastrointestinal stromal tumors (GIST) are the most frequently occurring form of mesenchymal tumors in the gastrointestinal tract. Laparoscopic sleeve gastrectomy (LSG) is a commonly performed bariatric operation in which a portion of the gastric body and fundus is removed and sent for pathological examination. Increasingly, bariatric surgeons have incidentally identified neoplasms in the excised portion of the stomach. The aim of this study is to explore the incidence of GIST in obese patients undergoing LSG. MATERIAL AND
methodsThis is a single-center, single-surgeon retrospective case series which included 305 obese patients who underwent LSG. All excised stomach specimens were sent for pathologic analysis.. In the case of pathologically verified GIST (n = 6; 1.97%), detailed analysis was performed.
resultsIn 305 LSG procedures, six cases of GIST (1.97%) were identified. The tumors were measured between 1 and 7 mm and were all low grade with negative resection margins. The mean BMI was 46.38 ± 3.94 kg/m
conclusionThe incidental rate of GIST in the excised portion of the stomach in our 305 obese patients who underwent LSG is 6/305 (1.97%). This adds relevant data to the overall goal of determining whether obesity is a risk factor for GIST. Radical surgical resection of these tumors with adequate disease-free margins performed on a low-grade malignancy serves as a definitive oncological treatment, especially when there is an intact pseudocapsule.
