Abstract
Background
Oesophageal leiomyomas are one of the most common benign oesophageal tumours. This retrospective, observational study summarized and compared the clinical outcomes of thoracoscopic enucleation of oesophageal leiomyoma between single-lumen endotracheal intubation with a bronchial blocker and double-lumen endotracheal intubation.
Methods
A total of 36 patients who underwent thoracoscopic enucleation of oesophageal leiomyoma at Peking Union Medical College Hospital between 2014 and 2020 were retrospectively analysed. Fifteen patients received single-lumen endotracheal intubation combined with a right bronchial blocker (SLT-B group), and twenty-one patients received double-lumen endotracheal intubation (DLT group). Clinical data, surgical variables, and postoperative complications were analysed and compared.
Results
The average tumour size in all patients was 4.3 ± 2.0 cm. The average tumour size among symptomatic patients was significantly larger than that among asymptomatic patients (5.1 ± 2.0 cm vs 3.7 ± 1.7 cm, P < 0.05). Patients in the SLT-B group had a significantly larger average tumour size than patients in the DLT group (5.4 ± 2.1 cm vs 3.5 ± 1.4 cm, P < 0.05). The SLT-B group had a significantly shorter operation time and shorter total hospital stay than the DLT group. No mucosal injury, conversion to thoracotomy, or other operative complications occurred in the SLT-B group. In the follow-up, no recurrence, dysphagia, or regurgitation was found in any of the patients.
Conclusions
Compared with traditional double-lumen intubation, artificial pneumothorax-assisted single-lumen endotracheal intubation combined with a bronchial blocker for thoracoscopic oesophageal leiomyoma enucleation can achieve complete removal of larger tumours, with fewer complications and shorter hospital stays.
