[Acute myopericarditis following laparoscopic treatment of gastroesophageal reflux].

A 32-year-old patient experienced a postoperative acute myopericarditis following laparoscopic surgery for gastro-oesophageal reflux (Toupet's fundoplication). His medical history was unremarkable, apart from controlled arterial hypertension. Peroperative circulation was stable, except a short hypertensive episode at CO2 insufflation, controlled with nicardipine. A myopericarditis occurred at the fourth postoperative hour, with apical and inferior hypokinesia at ventriculography, ST-segment elevation with unremarkable coronary arteriography. The patient was discharged at day seven, with a NSAIDs treatment. Echocardiography three and nine months later postoperatively, showed an apical akinesia and persistence of the ST-segment modification, without clinical symptoms. Complications of laparoscopic fundoplication is either specific to surgery (gastro-oesophageal injury, diaphragmatic injury, mediastinitis, stenosis) or secondary to pneumoperitoneum (pneumothorax, carbon dioxide embolism). In this case, following an apparently uncomplicated laparoscopy and, except a direct cardiac trauma from a laparoscopic instrument, either coronary artery spasm, or pneumopericardium with CO2, or delayed gas embolism, or preoperative "silent" myopericarditis could be the potential cause of this cardiac complication.
