Transthoracic hernia after harvesting a costal and latissimus dorsi flap.

Ribs are one of the most widely used grafts in craniofacial surgery. Harvesting a costochondral graft is easy and safe. The main complications are related to pneumothorax and chest-wall deformity in children. A complication is described in a patient who underwent an orbito-zygomatic reconstruction with two contiguous ribs and a latissimus dorsi free flap, and who subsequently developed a transthoracic hernia that required reconstruction with polypropylene mesh.

Intraoperative ultrasound during thoracoscopic procedures for solitary pulmonary nodules.

BACKGROUND: Traditional nonoperative diagnostic approaches to the solitary pulmonary nodule (bronchoscopy and percutaneous needle biopsy) can be inconclusive. Video-assisted thoracic surgery (VATS) provides a minimally invasive way to diagnose and treat these nodules. We evaluated the use of a dedicated intraoperative ultrasound probe as an aid in localization of small pulmonary nodules during VATS. METHODS: An intraoperative ultrasound examination during a thoracoscopic procedure was performed on 18 patients to localize deep pulmonary nodules less than 20 mm in diameter without a definitive diagnosis by preoperative imaging techniques. RESULTS: In the 18 patients, all nodules were successfully identified by intraoperative ultrasound. A definitive pathologic diagnosis was obtained from thoracoscopic biopsy or resection. The final diagnoses were primary lung cancer in 5 patients, metastatic lesions in 4 patients, hamartoma or chondroma in 4, granuloma in 3, and interstitial fibrosis in 2 patients. CONCLUSIONS: In our experience, intraoperative ultrasound can safely and effectively localize invisible or nonpalpable pulmonary nodules at the time of thoracoscopy. This may help surgeons perform minimally invasive lung resections with clear surgical margins.

Intraoperative ultrasonography (IOUS) during laparoscopic cholecystectomy.

BACKGROUND: The purpose of this study was to evaluate the usefulness of intraoperative ultrasonography (IOUS), a new method of imaging the biliary tree and related structures, during laparoscopic cholecystectomy. METHOD: An IOUS probe (Aloka, Tokyo, Japan) with a 7.5-MHz linear-array transducer was used during cholecystectomy in 124 patients with symptomatic cholelithiasis (45 men, 79 women; mean age, 48 +/- 14 years). RESULTS: The examination of the common bile duct (CBD) was excellent in 117 patients but unsatisfactory in 7 cases (5.6%) at the level of the head of the pancreas. In 5 patients, IOUS showed unsuspected choledocholithiasis: a subsequent intraoperational cholangiogram confirmed this. In five cases IOUS was able to help the surgeon to localize a Calot area obscured by inflammation. Postoperatively, one patient had an injury of the cystic duct stump: a nasobiliary tube resolved the bile leakage after 7 days. Another patient was submitted to postoperative endoscopic retrograde cholangiopancreatography (ERCP) for a choledocholithiasis recognized by a trans-cystic-tube cholangiography: the stone was suspected but not demonstrated either by laparoscopic IOUS or by intraoperative cholangiography. During the follow-up period, one patient had an episode of acute pancreatitis. ERCP showed a small stone wedged in the sphincter of Oddi. CONCLUSIONS: IOUS may be a real alternative to cholangiography during laparoscopic cholecystectomy since it is safer and offers a complete examination of the biliary tree. It has some disadvantages which can solved by additional experience.
