Esophageal perforation due to soft coagulation heat injury after right lower lobectomy: A case report.

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
introductionSoft coagulation is a hemostatic system of electrosurgical units that automatically regulates its output to avoid carbonization or incision. This system is widely used in invasive procedures, including thoracic surgery. Few reports exist on the harmful effects of these devices. Herein, we encountered a case of an esophagopleural fistula caused by soft coagulation. PRESENTATION OF CASE: A 74-year-old man with a history of bladder cancer was diagnosed with a tumor in the right lower lung lobe 2.5 cm in diameter. A thoracoscopic right lower lobectomy with lymph node dissection was performed. During surgery, hemostasis using soft coagulation was performed on the right wall of the lower esophagus. Eight days after surgery, thoracoscopic empyema curettage and drainage were performed. Three days after the second surgery, an esophageal fistula was identified. Suturing for the esophageal fistula and omentoplasty were performed. Suture failure occurred and an esophagobronchial fistula developed after the third surgery, which was reduced by drainage, antibiotics, and enteral nutrition. The fistula was finally addressed by fibrin glue filling in its cavity. DISCUSSION: Soft coagulation helps manage hemostasis and contributes to safe surgery. However, it may cause severe complications owing to the unpredictable spread of heat denaturation. It is suspected that delayed esophageal perforation was caused by an unnoticed heat injury to the deeper layer of the esophageal wall.
conclusionThere have been no reports of esophagus injury caused by soft coagulation exept for our experience. Although soft coagulation is a useful device owing to its excellent hemostatic capacity, the spread of heat denaturation may cause unpredictable tissue damage. Extra caution should be observed when using this device for hemostasis.
