Thoracoscopic Direct Suture Closure for a Large Bulla With Severe Adhesion Under Local Anesthesia: A Case Report.

Although the usefulness of thoracoscopic surgery under local anesthesia for pneumothorax has been reported, there are some cases of failure. Therefore, it is important to share the various techniques and potential challenges associated with procedures performed under local anesthesia. A 79-year-old male, under monitoring for a left chronic pneumothorax, was newly diagnosed with a right pneumothorax. Chest computed tomography taken after thoracic drainage showed a poorly expanded right lung with severe adhesions and multiple bullae in the right lung, in addition to identifying a left pneumothorax. Although significant air leakage persisted, general anesthesia was deemed unsuitable, necessitating thoracoscopic surgery under local anesthesia. A fistula of approximately 1 × 1 cm was identified on the bulla wall, which was closed with 4-0 Prolene®sutures (Johnson&Johnson, New Jersey, United States), each reinforced with pledgets and covered with a polyglycolic acid sheet and fibrin glue. The patient was discharged on postoperative day six and no recurrence of pneumothorax was noted after discharge. Direct suture closure of the bulla wall under local anesthesia can be an alternative technique for the treatment of pneumothorax caused by large bulla collapse in patients at high risk for general anesthesia.
