Enhanced recovery after surgery in elderly patients with non-small cell lung cancer who underwent video-assisted thoracic surgery

BACKGROUND This study was designed to investigate the clinical outcomes of enhanced recovery after surgery(ERAS)in the perioperative period in elderly patients with nonsmall cell lung cancer(NSCLC).AIM To investigate the potential enhancement of video-assisted thoracic surgery(VATS)in postoperative recovery in elderly patients with NSCLC.METHODS We retrospectively analysed the clinical data of 85 elderly NSCLC patients who underwent ERAS(the ERAS group)and 327 elderly NSCLC patients who received routine care(the control group)after VATS at the Department of Thoracic Surgery of Peking University Shenzhen Hospital between May 2015 and April 2017.After propensity score matching of baseline data,we analysed the postoperative stay,total hospital expenses,postoperative 48-h pain score,and postoperative complication rate for the 2 groups of patients who underwent lobectomy or sublobar resection.RESULTS After propensity score matching,ERAS significantly reduced the postoperative hospital stay(6.96±4.16 vs 8.48±4.18 d,P=0.001)and total hospital expenses(48875.27±18437.5 vs 55497.64±21168.63 CNY,P=0.014)and improved the satisfaction score(79.8±7.55 vs 77.35±7.72,P=0.029)relative to those for routine care.No significant between-group difference was observed in postoperative 48-h pain score(4.68±1.69 vs 5.28±2.1,P=0.090)or postoperative complication rate(21.2%vs 27.1%,P=0.371).Subgroup analysis showed that ERAS significantly reduced the postoperative hospital stay and total hospital expenses and increased the satisfaction score of patients who underwent lobectomy but not of patients who underwent sublobar resection.CONCLUSION ERAS effectively reduced the postoperative hospital stay and total hospital expenses and improved the satisfaction score in the perioperative period for elderly NSCLC patients who underwent lobectomy but not for patients who underwent sublobar resection.

Gastroparesis after video-assisted thoracic surgery:A case report

BACKGROUND Video-assisted thoracic surgery(VATS)lobectomy is a common treatment for patients with early-stage lung cancer.Some patients can experience slight gastrointestinal discomfort after lobectomy for a moment.Gastroparesis is a gastrointestinal disorder that can be severe;it is associated with an increased risk of aspiration pneumonia and impaired postoperative recovery.Here,we report a rare case of gastroparesis after VATS lobectomy.CASE SUMMARY A 61-year-old man underwent VATS right lower lobectomy uneventfully but had an obstruction of the upper digestive tract 2 d after surgery.Acute gastroparesis was diagnosed after emergency computed tomography and oral iohexol X-ray imaging.After gastrointestinal decompression and administration of prokinetic drugs,the patient’s gastrointestinal symptoms improved.Since perioperative medication was applied according to the recommended dose and there was no evidence of electrolyte imbalance,intraoperative periesophageal vagal nerve injury was the most likely underlying cause of gastroparesis.CONCLUSION Although gastroparesis is a rare perioperative complication following VATS,clinicians should be on the alert when patients complain about gastrointestinal discomfort.When surgeons resect paraesophageal lymph nodes with electrocautery,excessive ambient heat and compression of paraesophageal hematoma might induce vagal nerve dysfunction.

Video-assisted thoracic surgery―the past, present status and the future

Video-assisted thoracic surgery (VATS) has developed very rapidly in these two decades, and has replaced conven-tional open thoracotomy as a standard procedure for some simple thoracic operations as well as an option or a complementary procedure for some other more complex operations. In this paper we will review its development history, the present status and the future perspectives.

Application of video-assisted thoracic surgery in the standard operation for thoracic tumors

Objective： To evaluate the short-term outcomes of video-assisted thoracic surgery （VATS） for thoracic tumors. Methods： The data of 1,790 consecutive patients were retrospectively reviewed. These patients underwent VATS pulmonary resections, VATS esophagectomies, and VATS resections of mediastinal tumors or biopsies at the Cancer Institute ＆ Hospital, Chinese Academy of Medical Sciences between January 2009 and January 2012. Results： There were 33 patients converted to open thoracotomy （OT, 1.84%）. The overall morbidity and mortality rate was 2.79% （50/1790） and 0.28% （5/1790）, respectively. The overall hospitalization and chest tube duration were shorter in the VATS lobectomy group （n=949） than in the open thoracotomy （OT） lobectomy group （n=753）. There were no significant differences in morbidity rate, mortality rate and operation time between the two groups. In the esophageal cancer patients, no significant difference was found in the number of nodal dissection, chest tube duration, morbidity rate, mortality rate, and hospital length of stay between the VATS esophagectomy group （n=8 1） and open esophagectomy group （n=81）. However, the operation time was longer in the VATS esophagectomy group. In the thymoma patients, there was no significant difference in the chest tube duration, morbidity rate, mortality rate, and hospital length of stay between the VATS thymectomy group （n=41） and open thymectomy group （n=41）. However, the operation time was longer in the VATS group. The median tumor size in the VATS thymectomy group was comparable with that in the OT group. Conclusions： In early-stage （Ⅰ/Ⅱ） non-small cell lung cancer patients who underwent lobectomies, VATS is comparable with the OT approach with similar short-term outcomes. In patients with resectable esophageal cancer, VATS esophagectomy is comparable with OT esophagectomy with similar morbidity and mortality. VATS thymectomy for Masaoka stage I and II thymoma is feasible and safe, and tumor size is not contraindicated. Longer follow-ups are needed to determine the oncologic equivalency of VATS lobectomy, esophagectomy, and thymectomy for thymoma vs. OT.

Effect of Nalmefene on Delayed Neurocognitive Recovery in Elderly Patients Undergoing Video-assisted Thoracic Surgery with One Lung Ventilation

The intravenous use of nalmefene has been found to exert neuroprotective effect in patients with severe traumatic brain injury and acute cerebral infarction;nonetheless,it is unknown whether nalmefene alleviates delayed neurocognitive recovery.Our purpose of the current research was to clarify the impact of nalmefene on delayed neurocognitive recovery in aged patients experiencing video-assisted thoracic surgery(VATS)with intraoperative use of one lung ventilation(OLV).The present study involved 120 paticents undergoing selective VATS,randomized to accept low-dose nalmefene(N1 group,n=40),high-dose nalmefene(N2 group,1n=40)or equal volume of physiologic saline(control group,1=40).A battery of neuropsychological tests were used to estimate cognitive function I day before surgery(o)and 10 days after surgery or before discharge(t).Regional cerebral oxygen saturation(rSO2)was detected 5 min before induction(t),5 min after induction(1),15 and 60 min after onset of OLV(62 and 13),and 15 min after termination of OLV(4).The plasma values of interleukin(IL)-1β,IL-6,tumor necrosis factor(TNF)-a1 and adiponectin(ADP)were also detected prior to induction of anesthesia(T0),1 h,2 h and 6 h after surgery(TI,T2,T3).On 1,delayed neurocognitive recovery occurred in 5/40(12.5%)patients of NI group,in 5/40(12.5%)patients of N2 group and in 13/40(32.5%)patients of control group(P<0.05).There were no statistical differences in rSO2 among three groups at different time points.At Tl,T2 and T3,IL-1β,IL-6 and TNF-a values significantly increased and ADP value significantly decreased(P<0.05)in control group.In contrast,at TI,T2 and T3,IL-1β,IL-6 and TNF-a values decreased and ADP value decreased less in N1 and N2 groups(P<0.05).At TI,T2 and T3,IL-1β,IL-6 and TNF-a concentrations presented a trend of N2 group<N1 group<control group and ADP presented a trend of N2 group>Nl group>control group(P<0.05).The result of our present research supports the hypothesis that the perioperative intravenous treatment with nalmefene to VATS with OLV ameliorates postoperative cognitive function and decreases the incidence of delayed neurocognitive recovery,most likely by suppression of inflammatory responses.

Nonintubated video-assisted thoracic surgery under epidural anesthesia—Encouraging early results encourage randomized trials

Nonintubated video-assisted thoracic surgery （VATS） that is also defined awake VATS entails thoracoscopic procedures performed by regional anesthesia in spontaneously ventilating,mildly sedated or fully awake patients.

Partial removal of the pulmonary artery in video-assisted thoracic surgery for non-small cell lung cancer

Lobectomy with partial removal of the pulmonary artery in video-assisted thoracic surgery （VATS） currently remains a challenge for thoracic surgeons. We were interested in introducing pulmonary vessel blocking techniques in open thoracic surgery into video-assisted thoracic surgery （VATS） procedures. In this study, we reported a surgical technique simultaneously blocking the pulmonary artery and the pulmonary vein for partial removal of the pulmonary artery under VATS. Seven patients with non-small-cell lung cancer （NSCLC） received lobectomy with partial removal of the pulmonary artery using the technique between December 2007 and March 2012. Briefly, rather than using a small clamp on the distal pulmonary artery to the area of invading cancer, we replaced a vascular clamp with a ribbon and Hem-o-lock clip to block the preserved pulmonary veins so as to prevent back bleeding and yield a better view for surgeons. The mean occlusion time of the pulmonary artery and pulmonary veins were 44.0±10.0 and 41.3±9.7 minutes, respectively. The mean repair time of the pulmonary artery was 25.3±13.7 minutes. No complications occurred. No patients showed abnormal blood flow through the reconstructed vessel. There were no local recurrences on the pulmonary artery. In conclusion, the technique for blocking the pulmonary artery and veins is feasible and safe in VATS and reduces the risk of abrupt intraoperative bleeding and the chance of converting to open thoracotomy, and extends the indications of VATS lobectomy.

A comparative study of the therapeutic effect in two protocols: video-assisted thoracic surgery combined with laparoscopy versus right open transthoracic esophagectomy for esophageal cancer management

Objective: The aim was to evaluate the best intra-thoracoscopic surgery technique between video-assisted thoracic surgery (VATS) combined with laparoscopy and right open transthoracic esophagectomy, in patients with esophageal cancer. Methods: From November 2006 to May 2008, 221 patients with esophageal cancer were enrolled in this study, prospective randomized in two groups. 111 patients were performed the VATS technique (Experimental group), whereas in the other 110 patients esophagectomy was adopted by thoracotomy (Control group). Results: The time consuming of Experimental group was 272.3 min in average with a standard deviation(std) of 57.9, and it was 218.7 min in average with std of 91.0 in the control group (P=0.000). The operative blood loss was 219.7±194.4 mL in the Experimental group, compared with 590.0±324.4 mL in the control group, with significant difference (P=0.000). Postoperative hospital stay of Experimental group was 9.6±1.7d, and it was 11.4±2.3d in the control group (P=0.000). There was no-delayed union of incision in the Experimental group, but 6.36% in the control group (P=0.007). The disorder of gastric emptying occurred 0.9% in the Experimental group, whereas 6.4% in the Control group. There was no significant difference in survival curves and rates (P=0.555). Conclusion: There were several advantages of VATS technique, such as reduced hemorrhage, better recovery, few complications, and great number of lymph node dissection, although there was no significant difference in long-term survival rate. Thus the VATS combined with laparoscopy technique was worthy of generalization in esophageal surgery with good prospects.

Case Report:Pulmonary actinomycosis:a case undergoing resection through video-assisted thoracic surgery (VATS)

Actinomycosis is an uncommon disease, which is usually manifested as cervicofacial infection; related to poor oral hygiene or compromised immune function. Pulmonary actinomycosis is rare, but its diagnosis is changing due to its variable presentation; the similarity in appearance to other intrapulmonary diseases. Here we report an 80-year-old man with a solitary pulmonary nodule over the left upper lobe. Pulmonary neoplasm was highly suspected in this patient; thus resection of the mass was undertaken through video-assisted thoracic surgery (VATS). Histopathological examination demonstrated this patient had an Actinomyeces infection. While the application of VATS in patients with pulmonary actinomycosis has rarely been reported in literature, we conclude that VATS is valuable for the diagnosis; treatment of patients with undetermined pulmonary nodule(s).

Application of Video-Assisted Thoracic Surgery in the Standard Operation for Lung Tumors

OBJECTIVE To evaluate the indication and short-term outcomes of video assisted thoracic surgery （VATS） for lung tumors. METHODS Data of 306 consecutive patients undergoing VATS pulmonary resection between January 2009 and August 2010 in Cancer Institute ＆ Hospital, Chinese Academy of Medical Sciences were retrospectively reviewed. RESULTS There were 7 patients who underwent open thoracotomy, accounting for 2.29% （7/306）. The overall morbidity rate of complications and the mortality rate induced by VATS was 1.63% （5/306） and 0.33% （1/306）, respectively. There were no significant differences in morbidity and mortality rate between the patients receiving the VATS and the patients receiving the OT. The overall hospitalization, postoperative length of stay （LOS） and chest tube duration in the VATS lobectomy group （n = 167） were shorter than those in the open thoracotomy （OT）, but the operative time in the VATS group was longer than that in the OT group （n = 124）. There were no significant differences in the number of station of lymph nodal dissection （LND） and number of LND in pathological stage I between VATS group and OT group, but significant differences were found in the number of station of LND and the number of LND in pathological stage II and stage IIIA between the 2 groups. Compared with those who underwent OT wedge resection （n = 72）, the patients who underwent VATS wedge resection （n = 108） had shorter operative time, chest tube duration and hospital LOS, and there were no significant differences in morbidity of the complications and mortality between the 2 groups. CONCLUSION VATS lobectomy can be performed for patients with clinical stage I lung cancer （with tumor diameter smaller than 5 cm, without hilar and mediastinal lymph node enlargement）. VATS lobectomy is superior to OT lobectomy in short-term outcomes, although further studies exploring long-term outcomes through longer follow-up is needed to determine the oncologic equivalency between the VATS and the open lobectomy. VATS is also superior to OT in pulmonary wedge resection.

Video-Assisted Thoracic Surgery as a Less-Invasive Management for Acute Hemothorax in Blunt Trauma

Purpose: We report our experience of Video-assisted thoracic surgery (VATS) to treat acute blunt traumatic hemothorax using mini-thoracotomy. Methods: We designed a prospective study to determine if VATS with mini-thoracotomy benefits for patients with blunt traumatic hemothorax compared with conventional repair through full thoracotomy. Twenty-five patients underwent emergency operation for acute hemothorax from 2000. Five patients with less than 5% probability of survival (PS) were excluded, leaving 20 as the subjects. Results: Ten patients underwent conventional thoracotomy (conventional group) and the other 10 patients underwent VATS with mini-thoracotomy (VATS group). There was no difference between conventional group and VATS group in injury severity score (29.1 and 27.0) or PS (81.2% and 80.7%). Hospital mortality rates were 10% in conventional group and 0% in VATS group (N.S). Total amounts of intra-operative bleeding and post-operative transfusion until day 7 were 735 ml and 19.3 units in conventional group and 303 ml and 9.2 units in VATS group respectively (N.S). The length of ICU stay was 9.7 days in conventional group and 5.9 days in VATS group (N.S). Conclusion: VATS with mini-thoracotomy can be alternative for patients with blunt traumatic hemothorax in most emergency operations.

Effect of endobronchial blocker tube in the pulmonary carcinoma with video-assisted thoracic surgery

Objective:The aim of this study was to observe the effect of endobronchial blocker tube in the pulmonary carcinoma with video-assisted thoracic surgery.Methods:Forty patients of pulmonary carcinoma with video-assisted thoracic surgery were randomly assigned into two groups with twenty cases each:endobronchial blocker tube group(group 1) and double-lumen endobronchial tube group(group 2).After anesthesia was induced,in group 1,single lumen tube was intubated at first,and then endobronchial blocker tube intubated to left or right primary bronchus under the guidance of fiber-optic bronchoscope according to operational necessary,injected 2-4 mL air to blocker balloon and blocker one lateral primary bronchus for one-lung ventilation necessarily;while in group 2,the position of double-lumen endobronchial tube was confirmed with fiber-optic bronchoscope after intubation.Blood samples were collected before anesthesia induction,double lumen ventilation,at the one-lung ventilation of 5 min,30 min,60 min,120 min and 180 min,SBP,DBP,HR,SpO2,partial pressure of end tidal carbon dioxide(PetCO2),pH,PaO2,PaCO2,PaO2/FiO2 were recorded.Results:Forty cases' intubations were all successful.There were no differences in SBP,DBP,HR,SpO2,PetCO2,pH,PaCO2 between two groups in different points(P > 0.05).Paw in group 1 was lower than group 2,PaO2 and PaO2/FiO2 in group 1 was higher than group 2 in the one lung ventilation of 5 min,30 min,60 min,120 min and 180 min.Conclusion:The endobronchial blocker tube can meet the request of video-assisted thoracic surgery,with the special advantages of simple insertion,lower airway and better oxygenation.Endobronchial blocker tube offer a new way for one-lung ventilation in the pulmonary carcinoma with video-assisted thoracic surgery.

Video-assisted thoracoscopic surgery in thoracic oncology

Objective： The purpose of this study was to summarize and discuss the application of video-assisted thoracoscopic surgery （VATS） in the treatment of 58 chest cancers. Methods： The clinical data of 58 patients with thoracic tumor were analyzed retrospectively in treatment with VATS from July 2005 to June 2007. The surgery treatments included pulmonary wedge resection, enucleation of esophageal leiomyoma, bronchogenic cyst excision, mediastinal cyst excision, etc. Results： All patients were treated with VATS. Three patients of those with lung cancer underwent open-chest Iobectomy resection. All patients had no death and few complications, and all discharged. Conclusion： VATS has advantages of less trauma, suffering light, quick recovery and small postoperative complications and has a great advantage in the treatment of chest benign tumors. But in the treatment of chest malignant tumors we should strictly control indications.

Video-Assisted Thoracic Surgery for Residual Aneurysm after Total Arch Replacement

Background: Residual aneurysms after graft replacement are rare, but they can be detrimental if they are saccular and large. The etiology of residual aneurysms remains unknown, and their management is controversial. One treatment option is late open surgical conversion;however, postoperative respiratory complications resulting from the dissection of pleural adhesions, which is frequently necessary with this approach, are often unavoidable. Case presentation: Herein, we report a case of open surgical repair of a residual distal aortic arch aneurysm that occurred after total arch replacement and thoracic endovascular aortic repair. Contrast-enhanced magnetic resonance imaging was not possible in this case due to the patient’s severe renal dysfunction;however, contrast-enhanced computed tomography using minimal contrast did not detect remarkable leakage through the graft or stent graft into the aneurysm. Late open surgical conversion using video-assisted thoracic surgery was performed by thoracic surgeons, and the adhesion between the aortic wall and the lung was safely and effectively dissected. Because there was no significant pulsation or evidence of feeding arteries in the aortic wall, the aortic wall was opened carefully. No bleeding or backflow from any branch arteries into the aneurysm was noted, so the aortic wall was ligated with continuous sutures. The patient recovered without experiencing any major complications. Conclusions: This case report demonstrates that video-assisted thoracic surgery is safe and effective for late open conversion in cases of residual aneurysm;furthermore, this case suggests that video-assisted thoracic surgery may be particularly beneficial for the dissection of adhesions between the aortic wall and lung in these cases.

Evolving thoracic surgery: from open surgery to single port thoracoscopic surgery and future robotic

Thoracic Surgery is a continuous evolving specialty. In the past, thoracic surgeons had to make large incisions in order to operate any pathology inside the chest. This often meant big, painful and ugly scars and long recovery times after surgery. But he history of thoracic surgery changed since the begining of video-assisted thoracoscoDic surgery （VATg3

Uniportal Video-Assisted Thoracoscopic Surgery and Outcomes for Recurrent Primary Spontaneous Pneumothorax: Single-Institution Experience

Introduction: Primary spontaneous pneumothorax is relatively common condition in young adults. Uniportal video-assisted thoracoscopic surgery (uniportal VATS) has been accepted as a less invasive technique for the treatment of primary spontaneous pneumothorax. Strong evidence suggests that Uniportal VATS procedures are technically feasible and safe with excellent outcomes comparable to conventional VATS approach. Objectives: This article aims to discuss our experience with uniportal thoracoscopic approach as a valuable option in patients with recurrent spontaneous pneumothorax. Study Design: A retrospective study analysis between January 2014 and December 2016. Materials and Methods: From January 2014 to December 2016, 22 consecutive patients with unilateral recurrent spontaneous pneumothorax were to undergo uniportal video-assisted thoracic surgery (uniportal VATS). Their chronic residual postoperative pain, hospital stay and recurrence rate were analyzed. Results: Twenty-two patients with unilateral recurrent spontaneous pneumothorax were included;all received uniportal video-assisted thoracic surgery (uniportal VATS) and mechanical pleurodesis. Conclusions: We conclude that uniportal video-assisted thoracic surgery (uniportal VATS) demonstrated benefits to patients with primary spontaneous pneumothorax a safe, effective and also faster recovery, and decreased postoperative pain and short hospital stay.

The Application of Specific Nursing in Perioperative Patients of Thoracic Surgery and Postoperative Recovery and Improvement of Patients’ Negative Emotions

Objective: To study the application of specific nursing in perioperative patients of thoracic surgery and postoperative recovery and improvement of patients’ negative emotions. Patients and Methods: A total of 88 patients in the thoracic surgery operating room of our hospital were selected and divided into group A (specific nursing, n = 44) and group B (routine nursing, n = 44). The anxiety and depression status of the two groups were assessed by the Self-rating Anxiety Scale (SAS) and the Self-rating Depression Scale (SDS). The relevant respiratory parameters after surgery, including total lung capacity, maximum respiration flow-rate, tidal volume, and vital capacity were observed. The extubation time, ICU hospitalization time, and VAS scores of postoperative pain were compared, with a score of 10 being full. The higher the score, the higher the pain. The in-cidence of postoperative wound infection, pulmonary infection, respiratory tract infection and the satisfaction with the operation were compared. Sf-36 scale was used to score the physical function, life function, psychological function and quality of life of the patients in the two groups. Results: The surgical effect of group A was significantly higher than that of group B (all p < 0.05). The total lung capacity, maximum respiration flow-rate, tidal volume and vital capacity of group A were significantly higher than those of group B (all p < 0.05). The extubation time and hospitalization time of group A were significantly higher than those of group B (all p < 0.05). VAS score of group A was significantly lower than that of group B (all p < 0.05). The infection rate of group A was significantly lower than that in group B (all p < 0.05). Conclusion: Specific nursing has higher application value than routine nursing, which is worth further promotion in clinic.

Video-assisted Thoracoscopic Surgery for the Treatment of Mediastinal Lymph Node Tuberculous Abscesses

The mediastinal lymph node tuberculous abscesses（MLNTAs） are secondary to mediastinal tuberculous lymphadenitis. Surgical excision is often required when cold abscesses form. This study was aimed to examine video-assisted thoracoscopic surgery（VATS） for the treatment of MLNTA. Clinical data of 16 MLNTA patients who were treated in our hospital between December 1, 2013 and December 1, 2015 were retrospectively analyzed. All of the patients underwent the radical debridement and drainage of abscesses, and intrathoracic lesions were removed by VATS. They were also administered the intensified anti-tuberculosis treatment（ATT）, and engaged in normal physical activity and follow-up for 3 to 6 months. The results showed that VATS was successfully attempted in all of the 16 MLNTA patients and they all had good recovery. Two patients developed complications after surgery, with one patient developing recurrent laryngeal nerve injury, and the other reporting poor wound healing. It was concluded that VATS is easy to perform, and safe, and has high rates of success and relatively few side-effects when used to treat MLNTA.

Quality of Sleep at the Ward after Cardiothoracic Surgery

Objective: Sleeping problems are among the issues most mentioned by patients after cardiothoracic surgery. These problems can have a negative effect on duration of the hospital stay and recovery. In the ward of our cardiothoracic surgery department, a study was initiated to assess the quality of sleep after cardiothoracic surgery. The primary objective was to investigate the effect of cardiothoracic surgery on the quality of sleep. The secondary objective was to investigate the quality of sleep. Correlations with perioperative factors and related issues such as the type of surgery and medication were sought. Methods: A consecutive prospective cohort study was initiated (N = 72). The study used validated questionnaires to assess sleep: the Pittsburgh Sleep Quality Index (PSQI), the Epworth Sleepiness Scale (ESS), the Verran Snyder-Halpern Sleep Scale (VSH) and the Factors Influencing Sleep Quality (FISQ). Results: The PSQI showed that the quality of sleep one month after surgery was inferior to the quality of sleep before surgery (p-value: 0.03). The efficiency of sleep (time spent in bed) was higher after surgery then before surgery (p-value: 0.01). The VSH showed increased impaired sleep on the third night after surgery. The most disruptive factors were not being comfortable in a hospital bed, pain and the noise of medical devices. Conclusions: The quality of sleep after cardiothoracic surgery is worse when compared with the preoperative situation. The chief influencing factors are discomfort in bed, pain and disturbance from medical devices. The use of pain medication does not improve the quality of sleep.
