Delayed iatrogenic diaphragmatic hernia after thoracoscopic lobectomy.

Postoperative iatrogenic diaphragmatic hernia after thoracoscopic lobectomy is extremely rare. We present a 55-year-old female patient who developed an iatrogenic diaphragmatic hernia with gastric perforation several months after VATS (video-assisted thoracic surgery) left upper lobectomy with systematic lymphadenectomy. During the readmission, urgent laparotomy was performed.

Left lower sleeve lobectomy and systematic lymph node dissection by complete video-assisted thoracic surgery.

Sleeve lobectomy for selected cases of central lung cancer has better functional outcomes comparing to pneumonectomy. With improved technology and increased experiences in complete video-assisted thoracic surgery (VATS) lobectomy, complete VATS sleeve lobectomy has been applied in major medical centers recently. A 64-year-old male patient with left lower central lung cancer underwent thoracoscopic sleeve lobectomy and systemic mediastinal lymph node dissection.

Successful resection of a giant subpericardial lipoma with recurrent ventricular arrhythmias.

We report a case of a giant subpericardial lipoma with ventricular arrhythmias. It was resected through a median sternotomy without cardiopulmonary bypass. The tumour was about 21x23x5 cm and weighed 2100 g.

[Diagnosis and surgical treatment of giant intrathoracic solid tumors].

Objective: To summarize the experience in diagnosis and surgical treatment of giant intrathoracic solid tumors.

Methods: The data of surgically treated 36 patients with giant intrathoracic solid tumors were analyzed, including 19 males and 17 females. Complete resection was achieved in 34 cases with superior vena cava angioplasty in 3 cases and ligation of the left anonymous vein in 2 cases.

Coronary artery bypass grafting after pneumonectomy.

When open-heart operations are necessary in patients who have undergone pneumonectomy, the unavoidable shift of mediastinal structures should be carefully considered. Surgical access, revascularization procedures, and the institution of cardiopulmonary bypass can all require approaches that differ from the usual. In particular, no general recommendations exist regarding the management of patients who undergo coronary artery bypass grafting after pneumonectomy.

[Effect on synthesis of nitric oxide in myocardium by local cryoablation].

Objective: To study the effect on synthesis of nitric oxide in myocardium by local cryoablation and to investigate its mechanism.

Methods: Myocardium was cryoablated locally by a probe cooled to -60 degrees C and rewarmed by normal salt solution, nitric oxide and its synthesis enzyme were measured before and after cryoablation. L-arginine or methylene blue was added before and during cryoablation and the effect of these drugs on synthesis of nitric oxide was studied.
