Management of Gastric Leak after Sleeve Gastrectomy: A 13-year Experience in a Tertiary Referral Center.

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
introductionThe main complication of sleeve gastrectomy remains fistula formation. Studies have mainly focused on the endoscopic management of fistulas, and surgery is reserved for cases of hemodynamic instability or treatment failure. The aim of this study was to evaluate the management of gastric leak after sleeve gastrectomy.
methodsWe retrospectively analyzed the characteristics, treatments, and outcomes of patients managed for gastric leaks after sleeve gastrectomy in our center. Healing was defined as resumed oral intake without inflammatory syndrome or the presence of drainage material.
resultsFrom 2009 to 2022, 43 patients were managed in our center for gastric leak after sleeve gastrectomy. Among them, 21 patients were referred from other centers. In 86% of cases, the gastric leak developed within the first 15 days. It was located at the proximal staple line in 84% of cases. Associated stenosis or twisting was observed in 18% of cases. Surgical treatment alone was used in 32% of patients, while 59% received combined management. Only 3 patients (6.8%) were managed exclusively by endoscopy. The overall healing rate was 91%, with a median healing time of 89 days.
conclusionThe management of gastric leaks after sleeve gastrectomy depends on their location and clinical presentation and should not be limited to a solely endoscopic or surgical approach. Our study demonstrates that surgical intervention alone may be sufficient in 30% of cases. However, for most patients, a multidisciplinary approach in a referral center is recommended.
