Robot-assisted resection of oesophageal leiomyoma: a single-centre retrospective analysis of 57 cases.

Abstract

Backgrounds: Oesophageal leiomyoma is the most common benign tumour of the oesophagus, and complete tumour enucleation is the preferred treatment. The aim of this study is to evaluate the clinical application and technical advantages of Robotic-assisted Thoracoscopic Surgery (RATS) during the resection of oesophageal leiomyoma.

Methods: A retrospective study was conducted on patients who underwent robotic surgery for oesophageal diseases at our hospital from September 2017 to December 2023. Demographic statistics and clinical pathological characteristics, intraoperative and postoperative outcomes, immune histopathological staining, tumour pathology diagnosis and follow-up were analyzed.

Results: A total of 57 patients were enrolled in the study, including 42 males and 15 females with an average age of 49 years All patients received surgical treatment, with 54 patients undergoing robot-assisted resection of oesophageal tumour, one patient undergoing conversion to thoracotomy, and two patients undergoing exploratory surgery. The mean surgical time was 130 minutes, and the mean blood loss was 50 mL. Of the 55 patients who underwent tumour resection, 54 were pathologically diagnosed as oesophageal leiomyoma and one as atypical leiomyoma. Only one patient developed pulmonary infection after surgery, and there was no perioperative mortality. The average postoperative hospital stay was 9 days. All patients were followed up for a median time of 16 months (range: 1 to 70 months), and there was no recurrence or long-term complications after surgery.

Conclusion: Robot-assisted resection of oesophageal leiomyoma is safe and feasible, and can provide ideal short-and medium-term results.
