Association between perioperative cholesterol level and analgesia after video-assisted thoracoscopic surgery / 대한마취과학회지

BACKGROUND: Cholesterol plays an important role in the action of opioid analgesics, but its association with postoperative pain has not been clarified. Our study examined the association of pre- and postoperative total serum cholesterol (TSC), and change between the pre- and postoperative TSC levels with postoperative pain outcomes in patients with non-small cell lung cancer (NSCLC) who underwent video-assisted thoracoscopic surgery (VATS) lobectomy. METHODS: We retrospectively reviewed medical records of patients with NSCLC who underwent VATS lobectomy at the Seoul National University Bundang Hospital in South Korea. We sought to determine the association between preoperative TSC, TSC on postoperative day (POD) 0–1, and pre- and postoperative changes in TSC by comparing numeric rating scale (NRS) scores on POD 0, 1, and 2 and total morphine equivalent consumption on POD 0–2. Multivariate linear regression analyses were used, and P 0.05). In addition, the changes in TSC, preoperative TSC, and postoperative TSC were not associated with postoperative NRS pain score on POD 0, 1, and 2 (P > 0.05). CONCLUSIONS: Our results indicated that no significant association was observed between pre- and postoperative TSC level and postoperative pain outcome after VATS lobectomy of the lung.

Main Bronchial Reconstruction with Sparing of Pulmonary Parenchyma for Benign Diseases

Main bronchial reconstruction is anatomically suitable for benign main bronchial stenosis. But, it has been hardly recommended for operative mortality and morbidity. This study was aimed at providing validity and the proper clinical information of bronchoplasty for benign main bronchial stenosis by reviewing the results we obtained over the last ten years for main bronchial reconstruction operations. We retrospectively reviewed admission and office records. Twenty eight consecutive patients who underwent main bronchoplasty were included. Enrolled patients underwent main bronchial reconstruction for benign disease (tuberculosis in 21, trauma in 4, endobronchial mass in 3). Concomitant procedures with main stem bronchoplasty were performed in 19 patients. There were no incidences of postoperative mortality and significant morbidity. There were 2 cases of retained secretions, and these problems were resolved by bronchoscopy or intubation. All of the patients are still alive without obstructive airway problem. Bronchoplasty should be considered as one of the primary treatment modalities, if it is anatomically feasible.

Esophageal Squamous Cell Carcinoma Recurring as a Solitary Renal Mass / Journal of the Korean Cancer Association, 대한암학회지

Herein, a case of solitary, unilateral renal metastasis in a patient with curatively resected thoracic esophageal carcinoma, who achieved a pathological complete remission after neoadjuvant concurrent chemoradiotherapy, is reported. The kidney is the 4th or 5th most common visceral metastasis site of a primary esophageal carcinoma. More than 50% of renal metastases typically show bilateral involvement. Solitary, unilateral renal metastasis is extremely rare. Renal metastases from a primary esophageal carcinoma are usually latent and its diagnosis is very unusual in a live patient. The solitary renal metastasis in this case was not accompanied by metastases to other sites. The value of a nephrectomy in solitary renal metastasis of esophageal cancer is not known due to the rarity of such cases. A nephrectomy could be justified in limited situations, such as with uncertainty of histological diagnosis, severe life-threatening hematuria, which cannot be controlled by embolization, or solitary renal metastasis with a long disease-free interval.

Surgical Resection of Solitary Fibrous Tumors of the Pleura / 대한흉부외과학회지

BACKGROUND: Solitary fibrous tumors of the pleura (SFTP) is one of rare neoplasms that originated from submesothelial mesenchyme. Clinical course or extent of surgical resection is not well known. MATERIAL ANDMETHOD: We retrospectively reviewed all the clinical records of the patients who had undergone surgical resection of benign and malignant SFTP. RESULT: Twenty two (male : female 14 : 8) patients were enrolled and mean age was 50.2 (range 25~83). Number of symptomatic patients at the time of diagnosis was 13 (59%) and the most common symptom was dyspnea. Operative approach was carried out through thoracotomy (n=14) or video-assisted thoracic surgery (n=8). Mass excision was performed in 12 cases and en bloc resection including adjacent structure in 10 cases. In all cases complete resection was performed. There was no operative mortality. Malignant SFTP were 11 cases and benign SFTP 11 cases. Local recurrences (n=2) or distant metastasis (n=6) occurred only in malignant SFTP. CONCLUSION: Number of symptomatic patients, en bloc resection, and recurrence was more in malignant SFTP. Although complete surgical resection is known as treatment of choice for SFTP, further study should be performed about systemic therapeutic modalities pre- or postoperatively to control recurrence and metastasis.

Mucous Gland Adenoma Presenting as a Peripheral Lung Mass: A Brief Case Report

Mucous gland adenoma (MGA) of the lung is an uncommon, benign tumor that histologically resembles the mucus-secreting component of the tracheobronchial gland. The majority arises within the main, lobar or segmental bronchi. MGA presenting as a peripheral lung mass is extremely rare. We herein report a case of MGA that uniquely arose from the peripheral territory of the superior segmental bronchus of the left lower lobe in a 73-year-old male. Chest computed tomography showed a 13 mm-sized, subpleural nodule, which was easily enucleated by video-assisted thoracotomy. The mass was round and gray-tan in color with mucoid material. The tumor was composed of cysts, tubules, and glands lined by bland columnar, cuboidal or flattened, mucus secreting cells.
