Background: Surgical correction needs to be considered when diaphragm eventration leads to impaired ventilation and respiratory muscle fatigue. Plication to sufficiently tense the diaphragm by VATS is not as easy to achieve as plication by open surgery. We used pneumatic compression with carbon dioxide (CO2) gas in thoracoscopic diaphragmatic plication and evaluated feasibility and efficacy. Methods: Eleven patients underwent thoracoscopic diaphragmatic plication between January 2008 and December 2013 in Pusan National University Hospital. Medical records were retrospectively reviewed, and compared between the group using CO2 gas and group without using CO2 gas, for operative time, plication technique, duration of hospital stay, postoperative chest tube drainage, pulmonary spirometry, dyspnea score pre- and postoperation, and postoperative recurrence. Results: The improvement of forced expiratory volume at 1 second in the group using CO2 gas and the group not using CO2 gas was 22.46±11.27 and 21.08±5.39 (p=0.84). The improvement of forced vital capacity 3 months after surgery was 16.74±10.18 (with CO2) and 15.6±0.89 (without CO2) (p=0.03). During follow-up (17±17 months), there was no dehiscence in plication site and relapse. No complications or hospital mortalities occurred. Conclusion: Thoracoscopic plication under single lung ventilation using CO2 insufflation could be an effective, safe option to flatten the diaphragm.

With advancement of the technique of video-assisted thoracic surgery (VATS), some surgeons have made great efforts to reduce the number of incisions in the conventional three- or four-port approach. Several studies on cases treated by single-incision VATS and their short-term outcomes were reported. Here, we present our experience with single-incision VATS for the treatment of benign mediastinal diseases.
Endoscopic Intraluminal Drainage: An Alternative Treatment for Phlegmonous Esophagitis
김종원,안효영,김광하,김영대,이호석,조정수 대한흉부외과학회 2019 Journal of Chest Surgery (J Chest Surg) Vol.52 No.3
Phlegmonous esophagitis must be treated aggressively; therefore, appropriate antibiotic therapy and drainage are critical. Although a conventional surgical approach has been used previously, internal drainage could be another treatment option in light of advances in endoscopic techniques. We report 2 cases in which patients suffering from phlegmonous esophagitis were successfully treated with endoscopic intraluminal drainage and antibiotics.

Here, we report the rare case of a 13-year-old girl with a congenital diaphragmatic her- nia (also known as Bochdalek hernia), which was revealed to be an extralobar pulmonary sequestration that was treated using laparoscopic and video-assisted thoracic surgery se- questrectomy and repair of the diaphragm defect after detection of a supradiaphragmatic mass connected with the retroperitoneum. The patient showed no postoperative compli- cations at a 1-month follow-up examination.
Location of Ruptured Bullae in Secondary Spontaneous Pneumothorax

Background: The surgical treatment of secondary spontaneous pneumothorax (SSP) can be complicated by fragile lung parenchyma. The preoperative prediction of air leakage could help prevent intraoperative lung injury during manipulation of the lung. Common sites of bulla development and ruptured bullae were investigated based on computed tomography (CT) and intraoperative findings. Methods: The study enrolled 208 patients with SSP who underwent air leak control through video-assisted thoracoscopic surgery (VATS). We retrospectively reviewed the sites of bulla development on preoperative CT and the rupture sites during VATS. Results: Of the 135 cases of right-sided SSP, the most common rupture site was the apical segment (31.9%), followed by the azygoesophageal recess (27.4%). Of the 75 cases on the left side, the most common rupture site was the apical segment (24.0%), followed by the anterior basal segment (17.3%). Conclusion: The azygoesophageal recess and parenchyma along the cardiac border were common sites of bulla development and rupture. Studies of respiratory lung motion to measure the pleural pressure at the lung surface could help to determine the relationship between cardiogenic and diaphragmatic movement and bulla formation or rupture.

Pancreaticopleural fistula (PPF) is a rare complication in patients with pancreatitis. Its symptoms are similar to those of empyema or pleural effusion; therefore, it is important to consider PPF in the differential diagnosis. Herein, we describe the diagnosis and treatment of PPF in a patient presenting with unusual empyema and delayed hemoptysis.
