[Surgical Therapy of Slipping Rib Syndrome].

We have operated on two cases of slipped ribs syndrome( SRS). Both patients were men in their 40s with a history of right thoracic trauma who were referred to us because of unexplained lower thoracic pain. The left rib was positive for hooking maneuver (lift test), and dynamic ultrasonography showed narrowing of the intercostal space, which led to the diagnosis of SRS. in the first case, the tip of the ninth rib cartilage was excised, and the ninth and tenth rib cartilages were sutured and fixed with No.2 fiber wire in two places with Z sutures. In the second case, the tip of the ninth rib cartilage was excised, the eighth and ninth ribs and the ninth and tenth ribs were fixed with No.2 fiber wire with Z sutures as in the first case, and a 0.7 mm thick poly-L-lactide (PLLA) plate was added between the eighth and tenth rib cartilages. In both cases, the postoperative course was good and the pain disappeared. SRS should be recognized as a disease and surgical treatment should be used as therapy.

[Thoracoscopic Right Upper Lobectomy in a Patient with a Right Aortic Arch:Report of a Case].

It has been reported that the recurrent nerve may not be recognized during mediastinal lymph node dissection in surgery for right upper lobe lung cancer associated with the right aortic arch. In the present case, a 66-year-old man underwent thoracoscopic right upper lobectomy for right upper lobe lung cancer associated with the right aortic arch. The gap between the superior vena cava and descending aortic arch was narrow, and the vagus nerve ran between the superior vena cava and the aorta. The recurrent laryngeal nerve was able to confirm. The vagus nerve ran the hilum of lung back side from arch of azygos vein on the peripheral side. The morphology of the right aortic arch varies from case to case, and if the vagus nerve and recurrent nerve are difficult to identify, the nerve may be hidden by the superior vena cava. If the nerve cannot be recognized, the space between the superior vena cava and the aorta should be dissected and confirmed. In addition, taping the vagus nerve and observing it from the caudal to the cephalic side may be useful for the recurrent nerve that turns to the mediastinum. In this case, magnification of the thoracoscope is extremely useful.
