Outcomes after hybrid minimally invasive treatment of Boerhaave syndrome: a single-institution experience.

Background: Spontaneous esophageal perforation or Boerhaave syndrome is a life-threatening emergency, associated with significant morbidity and mortality. In this retrospective series we describe our single-center experience with a hybrid minimally invasive treatment approach for the treatment of Boerhaave syndrome. Methods: Clinical data of all patients who presented with spontaneous esophageal rupture between January 2009 and December 2019 were analyzed. All patients underwent esophageal endoscopic stenting to seal the perforation and debridement of the contaminated mediastinal and pleural cavity through video-assisted thoracoscopic surgery (VATS). Primary outcome measure was defined as in-hospital death and 30-day mortality. Results: Twelve patients were included with a median age of 63 years (interquartile range [IQR] 51-74 years) of whom 58% (n = 7) were male. The median Pittsburg perforation severity score was 6.5 (IQR 6-9). Endoscopic reintervention was required in 8 patients (67%), primarily due to stent dislocation. In addition, 5 patients (42%) required re-VATS due to empyema formation. Thirty-day mortality and in-hospital mortality were respectively 17% (n = 2) and 25% (n = 3). Conclusion: Endoscopic stenting in combination with thoracoscopic debridement is an effective and safe minimally invasive hybrid approach for the treatment of Boerhaave syndrome. This is depicted by the relatively low mortality rates, even among patients with high perforation severity scores. The relatively low mortality rates may be attributed to the combined approach of rapidly sealing the defect and decontamination of the thorax. Future studies should aim to corroborate this evidence which is limited by its sample size and retrospective nature.
