A case series: uniportal VATS excision of pericardial cysts in symptomatic patients

Abstract

Background Pericardial cysts are infrequent lesions. Most of these are asymptomatic and incidental findings during investigations for unrelated conditions. When they are symptomatic, they demonstrate most of the time a benign clinical course. Yet, treatment is sometimes necessary. Besides a (temporary) treatment as percutaneous aspiration, there is surgery as a definite treatment. The aim of the paper is to motivate the safety and efficacy of uniportal video assisted thoracoscopy (UVATS) for the excision of (giant) pericardial cysts and describe their (peri-)operative technique. Methods In this retrospective, single center-based case series, we report all cases with a pericardial cyst who underwent a surgical excision by uniportal VATS (UVATS) between March 2022 and April 2023. Detailed patient characteristics, operation details, hospital length of stay and follow-up data were collected. Results A total of 4 patients underwent excision of a pericardial cyst by UVATS. The follow-up ranged from 10 to 20 months. The mean diameter of the pericardial cyst was 124 mm. Median procedure time was 94 min. No per- and postoperative complications occurred. The median length of postoperative hospital stay was 2 days. All patients showed a clinically relevant improvement of the pre-operative symptoms. Conclusions Uniportal VATS excision for pericardial cysts is a safe and effective surgical procedure with good outcomes on symptom relief. Though, future comparative studies are urged to elucidate its value among other treatment options.
