Simultaneous thoracoscopic approach in a patient with long-standing persistent atrial fibrillation and primary lung cancer: the first described case

Abstract Cardiac rhythm disorders are common in many patients with cancer. The management of synchronous long-standing persistent atrial fibrillation and pulmonary lesions remains a serious surgical dilemma due to the lack of clinical data and surgical guidelines. To the best of our knowledge, this is the first described case of simultaneous thoracoscopic pulmonary segmentectomy and left atrial posterior wall and pulmonary vein isolation combined with left atrial appendage resection in a patient with early-stage primary lung cancer and long-standing persistent atrial fibrillation.

Primary Pulmonary Chordoid Meningioma

Primary pulmonary meningioma is a rare disease, and chordoid meningioma is an uncommon variant of meningioma in the central nervous system (CNS) with a high recurrence rate. We report a case of primary pulmonary chordoid meningioma that presented as a solitary pulmonary nodule (SPN). The SPN was resected by thoracoscopic wedge resection and was revealed to have characteristics of chordoid meningioma. After confirming the absence of a meningioma in the CNS by brain imaging, the nodule was diagnosed as a primary pulmonary chordoid meningioma. The patient remained disease-free after 26 months postoperatively. To our knowledge, this is the third case of primary pulmonary chordoid meningioma to be reported.

Lobectomy in octogenarians with clinical stage Ⅰ non-small cell lung cancer-ten years of experience in a single center / 中华胸心血管外科杂志

Objective As the population ages,clinicians are increasingly confronted with octogenarians with early-staged non-small cell lung cancer(NSCLC).We reviewed the outcomes of octogenarians who underwent lobectomy for clinical stagc Ⅰ NSCLC,to determine whether there was a benefit to the VATS approach in this group,and to analysis the risk factors of complication and survival.Methods We conducted a retrospective single-institution review of patients age 80 years or greater who underwent lobectomy for NSCLC from January 2006 to December 2016.Clinical outcomes including complication rate and survival rate were analyzed.Results 162 octogenarians underwent lobectomy:98 VATS and 64 through open thoracotomy.Compared with thoracotomy,VATS patients had fewer complications (14.3 ％ vs.28.1％,P =0.03),shorter length of tube duration [(3.5 ± 1.5) days vs.(4.9 ± 2.0) days,P =0.04],and shorter length of stay [(5.5 ± 2.1) days vs.(7.8 ± 3.5) days,P =0.04].For patients with pathologic stage Ⅰ disease,the 5-year overall survival was 64.5％,for stage Ⅱ was 38.1％,and for stage Ⅲ was 20.1％.The 5-year overall survival rates of pathological stage Ⅰ and stage Ⅱ,Ⅲ are of significant differences(P =0.001).In a multivariate logistic regression analysis,the approach of thoracotomy emerged as an independent predictor of complication (OR =1.94,95％ CI 1.214-5.135,P =0.03).In a multivariate COX regression analysis,pathological stage(OR =2.01,95％C1 1.453-5.865,P=0.03) and ASA(OR =1.81,95％CI 1.188-4.015,P =0.04) are independent predictors of over survival.Conclusion Octogenarians with NSCLC can undergo resection with low mortality and survival among stage Ⅰ patients,which is comparable with the general lung cancer population.The VATS approach reduces morbidity in this age demographic,resulting in shorter length of tube duration and shorter stay,while the approach of thoracotomy is an independent predictor of complication.Our study also demonstrated that pathological stage and ASA are independent predictors of overall survival rate.

Retrospective study on evaluatoi n of video-assisted thoracoscopic lobectomy of mediastinal lymph nodes / 实用肿瘤学杂志

Objective The aim of this study is to evaluate whether video -assisted thoracoscopic surgi-cal( VATS) lobectomy is as effective as open thoracotomy lobectomy for complete dissection of the mediastinal lymph node(MLN).Methods Patients with clinical stage N0 lung cancer who underwent lobectomy between January 2008 and June 2013were retrospectively evaluated based on the LN station resected and lobectomy proce -dure used,and a resection ratio was calculated .Nodal stage and the proportion of patients ,from whom at least three MLNs and station 7were dissected and compared by lobectomy type .Results Of the 201 patients enrolled in the study,84 and 117 underwent VATS and open thoracotomy lobectomies ,respectively.The mean number of LNs dissected at station 3a was similar in the two groups (1.34 ±2.58 vs.1.52 ±1.78;P>0.05),but the re-section ratio differed(39%sv .63%;P 0.05).There were no differences in the number of LNs dissected or resection ratio between the two groups for stations 4 L,5 L6, L,7 L, and9 L for the left-sided approaches .Only station 8L showed significant differences between the VATS and open thoracotomy groups in the number of LNs dissected (0.12 ±0.44 vs.0.46 ±0.71;P0.05). The Kaplan-Meier 5-year survival was also similar between the two groups (log-rank test,P>0.05).Con-clusion VATS lobectomy is as effective as open thoracotomy lobectomy for the dissection of MLNs .Thus,VATS lobotomy resection will continue to be offered as the best choice for patients with clinical stage N0.

The safety of 66 two-incision VATS in treating clinical early staged lung cancer / 实用肿瘤学杂志

Objective Two-incision video-assisted thoracic surger relieved post operative pain when compared with open thoractomy ,while it is rarely reported worldwide ,most thoracic surgeons think it is hard to finish the complicated operation and it is not safe .We compared the safety between open and two -incision VATS.Methods Bwteen Febrary 2009 to December 2011 ,a total of 334 cases with clinical early -staged lung cancer of open thoracotomy were performed ,66 cases were completely performed with 2-incision VATS,17 cases were transferred to open thoracotomy defined as two -incision VATS assisted thoracotomy .We compared and ana-lyzed open thoracotomy with two -incision VATS in operating time ,and pre,post and total period of hospitaliza-tion,postoperative chest tube removal time ,postoperative complications .Results Operating time in the left lower lobe of both traditional open thoracotomy and two -incision VATS was 162.5 ±6.5 and 185.8 ±12.8 minutes re-spectively(P=0.1228),there was no statistical significance for the remaining parts of the lobectomy ,the operat-ing time of open thoracotomy was shorter than two -incision VATS.The overall complication and perioperative mortality rate of open thoracotomy and two -incision VATS were 10.2% and 15.0%(P=0.238),and 2.0%and 0.0%(P=1.000)respectively,there was no statistical significance.Conclusion The lobectomy and lymph node dissections for 2-incision VATS in treating clinical stage I lung cancer is feasible and safe .
