Research advances in diagnosis and treatment strategy of solitary pulmonary nodule / 天津医药

The detection rate of solitary pulmonary nodule (SPN) is significantly increased with the widespread application of chest computed tomography (CT) scans. Therefore, there is rising demand and expectation for more accurate diagnostic tests to characterize SPN. The different diagnostic methods currently used in clinical practice have their advantages and disadvantages. This article reviews the literature pertaining to SNP diagnosis and treatment strategy and above mentioned concerns according to Fleischner society, American College of Chest Physicians (ACCP) and National Comprehensive Cancer Network (NCCN) screening guideline.

Application of Habib 4X in hepatic resection / 中华消化外科杂志

Objective To investigate the value of Habib 4X in hepatic resection. Methods The clinical outcome of 21 patients with liver disease who received liver resection at the Tianjin Third Central Hospital from November 2009 to April 2010 were retrospectively evaluated. All the operations were carried out by using Habib 4X. Results All patients received hepatectomy, including right hepatectomy in three patients, left hepatectomy in one patient, multiple segmentectomy in nine patients, single segmentectomy in seven patients and partial liver resection in one patient. All tumors were reseeted completely. The mean operation time was (50±25) minutes and the mean blood loss was(129±117)ml. No patient was transferred to ICU. Three patients were complicated with bile leakage, one with lymphatic leakage and four with pleural effusion, and they were cured by non-surgical treatment. There were no patients with postoperative hemorrhage, incision infection or hepatic failure. No mortality was observed. The mean postoperative hospital stay was(19±14)days. Conclusions Radiofrequency energy was applied along the margins of the tumor to create zones of necrosis before resection with a scalpel, offering hepatobiliary surgeons an additional method for performing liver resections with minimal blood loss, low morbidity and mortality rates. As for malignant tumors, minor or major liver resection assisted by Habib 4X is safe, and it can reduce the chance of positive incisal margin.
