Study summary

During patient follow up the investigators noticed the occasional occurence of a lung herniation after uniportal Video assisted thoracoscopic surgery (VATS). Most of These patients were asymptomatic and didn't require any kind of treatment. To analyse the incidence of postoperative lung herniation after uniportal and the presence of symptoms the investigators decided to review every postoperative CT scan from January 2016 until March 2019 to radiologically identify postoperative lung herniations. Afterwards the investigators will contact the respective patient to ask for a follow-up physical examination and symptom evaluation (after consent was signed).
