Hybrid NOTES transgastric cholecystectomy with reliable gastric closure: an animal survival 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
backgroundSecure transluminal closure remains the most fundamental barrier to safe translation of transgastric natural orifice transluminal endoscopic surgery (NOTES) procedures to humans. Obtaining optimal critical view of safety (CVS) is a prerequisite to performing cholecystectomy avoiding common bile duct injury.
objectives(1) To evaluate feasibility and safety of hybrid transgastric NOTES cholecystectomy. (2) To evaluate feasibility and reliability of gastrotomy closure using a novel Over-The-Scope-Clip (OTSC; Ovesco) in survival porcine experiments.
methodsLaparoscopic access to the abdominal cavity was obtained by two 2-mm and one umbilical optical trocar(s). Gastric access was created by balloon dilatation of a needle knife puncture up to 18 mm. Exposure of CVS was obtained and evaluated by aid of a 2-mm device. Subsequently the cystic duct and artery were clipped endoscopically. After laparoscopic dissection the specimen was extracted via the stomach. The gastrotomy was closed endoscopically using the OTSC. Necropsy was performed after 10 days with inspection of gastrotomy and peritoneal cavity for complications. Experiments were planned in 3 acute and 16 survival pigs. Main outcome parameters were documented exposure of CVS, successful cholecystectomy and closure, uncomplicated survival and histology-confirmed full-thickness closure.
resultsIn all 16 survival experiments CVS was obtained satisfactorily and hybrid cholecystectomy was successfully performed [100%; 95% confidence interval (CI): 81-100%]. Transgastric closure was endoscopically successful in all experiments in mean time of 7 min [standard deviation (SD) 3 min]. At necropsy 10 days after surgery there were no signs of (infectious) complications. Histology confirmed full-thickness healing with 100% success (95% CI: 81-100%).
conclusionHybrid transgastric NOTES cholecystectomy is feasible, safe and results in optimal CVS. Use of OTSC for gastrotomy closure is feasible, reliable and results in histology-proven full-thickness closure in survival porcine experiments.
