Early chest tube removal regardless of drainage volume after anatomic pulmonary resection: A multicenter, randomized, controlled trial

OBJECTIVES

This study aimed to evaluate the safety and feasibility of early chest tube removal after anatomic pulmonary resection, regardless of the drainage volume.

METHODS

We conducted a multicenter, randomized, controlled, noninferiority trial. Patients with greater than 300 mL drainage volume during postoperative day 1 were randomly assigned to group A (tube removed on postoperative day 2) and group B (tube retained until drainage volume ≤300 mL/24 hours). The primary end point was the frequency of respiratory-related adverse events (grade 2 or higher based on the Clavien-Dindo classification) within 30 days postoperatively.

RESULTS

Between April 2019 and October 2021, 175 patients were assigned to group A (N = 88) or group B (N = 87). One patient in group B who experienced chylothorax was excluded from the study. Respiratory-related adverse events were observed in 10 patients (11.4%) in group A and 12 patients (14.0%) in group B (P = .008). The frequencies of thoracentesis or chest tube reinsertion were not significantly different (8.0% and 9.3% in groups A and B, respectively, P = .752). Additionally, the duration of chest tube placement was significantly shorter in group A than in group B (median, 2 vs 3 days; P < .001). No significant difference between groups A and B was found in postoperative hospital stay (median, 6 vs 7 days, P = .231).

CONCLUSIONS

Early chest tube removal, regardless of drainage volume, was safe and feasible in patients who underwent anatomic pulmonary resection.

Comparisons in analgesic effects between ultrasound-guided erector spinae plane block and surgical intercostal nerve block after video-assisted thoracoscopic surgery: A randomized controlled trial

STUDY OBJECTIVE

This study aimed to compare the analgesic effects of anesthesiologist-administrated erector spinae plane block (ESPB) and surgeon-administrated intercostal nerve block (ICNB) following video-assisted thoracoscopic surgery (VATS).

DESIGN

Randomized, controlled, double-blinded study.

SETTING

Operating room, postoperative recovery room and ward in two centers.

PATIENTS

One hundred patients, ASA I-III and scheduled for elective VATS.

INTERVENTIONS

The anesthesiologist-administrated ESPB under ultrasound guidance or surgeon-administrated ICNB under video-assisted thoracoscopy was randomly provided during VATS. Regular oral non-opioid analgesic combined with intravenous rescue morphine were prescribed for multimodal analgesia after surgery.

MEASUREMENTS

The primary outcomes were the pain score and morphine consumption during 48 h after surgery. Postoperative pain intensity were assessed using the 10-cm visual analogue scale at 1 h, 24 h, and 48 h after surgery. Morphine consumption at these time points was compared between the two study groups. Furthermore, oral weak opioid rescue analgesic was also provided at 24 h after surgery. Postoperative quality of recovery at 24 h was also assessed using the QoR-15 questionnaire, along with duration of chest tube drainage and hospital stay were compared as secondary outcomes.

MAIN RESULTS

Patients in the two study groups had comparable baseline characteristics, and surgical types were also similar. Postoperative VAS changes at 1 h, 24 h, and 48 h after surgery were also comparable between the two study groups. Both groups had low median scores (<4.0) at all time points (all p > 0.05). Patients in the ESPB group required statistically non-significant higher 48-h morphine consumption [3 (0-6) vs. 0 (0-6) mg in the ESPB group and ICNB group respectively; p = 0.135] and lower numbers of oral rescue analgesic (0.4 ± 1.2 vs. 1.0 ± 1.8 in the ESPB group and ICNB group respectively; p = 0.059). Additionally, patients in the two study groups had similar QoR15 scores and lengths of hospital stay.

CONCLUSIONS

Both anesthesiologist-administered ultrasound-guided ESPB and surgeon-administered VATS ICNB were effective analgesic techniques for patients undergoing VATS for tumor resection.

Safety of one 8.5-Fr pigtail catheter for postoperative continuous open gravity drainage after uniportal video-assisted thoracoscopic surgery pneumonectomy

OBJECTIVES

Uniportal video-assisted thoracoscopic surgery pneumonectomy (U-VATS-P) is feasible and safe from a perioperative standpoint. How to choose the proper chest tube and drainage method is important in enhanced recovery after surgery (ERAS) protocols. In this study, we aimed to assess the safety of one 8.5-Fr (1Fr = 0.333 mm) pigtail catheter for postoperative continuous open gravity drainage after U-VATS-P.

METHODS

We retrospectively reviewed a single surgeon's experience with U-VATS-P for lung cancer from May 2016 to September 2022. Patients were managed with one 8.5-Fr pigtail catheter for postoperative continuous open gravity drainage after U-VATS-P. The clinical characteristics and perioperative outcomes of the patients were retrospectively analyzed.

RESULTS

In total, 77 patients had one 8.5-Fr pigtail catheter placed for postoperative continuous open gravity drainage after U-VATS-P for lung cancer. The mean age was 60.9±7.39 (40-76) years; The mean FEV1 was 2.1±0.6 (l/s), and the mean FEV1% was 71.2±22.7. The median operative time was 191.38±59.32 min; the mean operative hemorrhage was 109.46±96.56 ml; the mean duration of postoperative chest tube drainage was 6.80±2.33 days; the mean drainage volumes in the first three days after operation were 186.31±50.97, 321.97±52.03, and 216.44±35.67 ml, respectively; and the mean postoperative hospital stay was 7.90±2.58 days. No patient experienced complications resulting from chest tube malfunction. Ten patients experienced minor complications. One patient with nonlife-threatening empyema and bronchopleural fistula required short rehospitalization for anti-inflammatory therapy and reintubation. Three patients with chylothorax were treated with intravenous nutrition. Four patients had atrial fibrillation that was controlled by antiarrhythmic therapy. Two patients had more thoracic hemorrhagic exudation after the operation, which was found in time and was cured effectively, so they were discharged from the hospital uneventfully after early hemostatic therapy and nutritional support.

CONCLUSIONS

All patients in this study received early postoperative rehabilitation, and the rate of relevant complications was low. We therefore recommend a single 8.5-Fr pigtail catheter for postoperative continuous open gravity drainage as an effective, safe and reliable drainage method for the management of U-VATS-P.

Safety and efficacy of new staple-line reinforcement in lung resection: a prospective study of 48 patients

PURPOSE

To evaluate the safety and efficacy of new staple-line reinforcement (SLR) in pulmonary resection through a prospective study and to compare the results of this study with historical control data in an exploratory study.

METHODS

The subjects of this study were 48 patients who underwent thoracoscopic lobectomy. The primary endpoint was air leakage from the staple line. The secondary endpoints were the location of air leakage, duration of air leakage, and postoperative pulmonary complications.

RESULTS

The incidence of intraoperative air leakage from the staple line was 6.3%. Three patients had prolonged air leakage as a postoperative pulmonary complication. No malfunction was found in patients who underwent SLR with the stapling device. When compared with the historical group, the SLR group had a significantly lower incidence of air leakage from the staple line (6.3% vs. 28.5%, P < 0.001) and significantly shorter indwelling chest drainage time (P = 0.049) and length of hospital stay (P < 0.001).

CONCLUSIONS

The use of SLR in pulmonary resection was safe and effective. When compared with conventional products, SLR could control intraoperative air leakage from the staple line and shorten time needed for indwelling chest drainage and the length of hospital stay.

Rectus sheath block added to parasternal block may improve postoperative pain control and respiratory performance after cardiac surgery: a superiority single-blinded randomized controlled clinical trial

BACKGROUND

The population undergoing cardiac surgery confronts challenges from uncontrolled post-sternotomy pain, with possible adverse effects on outcome. While the parasternal block can improve analgesia, its coverage may be insufficient to cover epigastric area. In this non-blinded randomized controlled study, we evaluated the analgesic and respiratory effect of adding a rectus sheath block to a parasternal block.

METHODS

58 patients undergoing cardiac surgery via median sternotomy were randomly assigned to receive parasternal block with rectus sheath block (experimental) or parasternal block with epigastric exit sites of chest drains receiving surgical infiltration of local anesthetic (control). The primary outcome of this study was pain at rest at extubation. We also assessed pain scores at rest and during respiratory exercises, opiate consumption and respiratory performance during the first 24 hours after extubation.

RESULTS

The median (IQR) maximum pain scores (on a 0-10 Numeric Rate Scale (NRS)) at extubation were 4 (4, 4) in the rectus sheath group and 5 (4, 5) in the control group (difference 1, p value=0.03). Rectus sheath block reduced opioid utilization by 2 mg over 24 hours (IC 95% 0.0 to 2.0; p<0.01), reduced NRS scores at other time points, and improved respiratory performance at 6, 12, and 24 hours after extubation.

CONCLUSION

The addition of a rectus sheath block with a parasternal block improves analgesia for cardiac surgery requiring chest drains emerging in the epigastric area.

Postoperative day 1 discharge following subxiphoid thoracoscopic anatomical lung resection: a single-centre, postoperative enhanced recovery experience

OBJECTIVES

The goal of this study was to assess the safety and quality of recovery (QOR) after discharge on postoperative day (POD) 1 following subxiphoid thoracoscopic anatomical lung resection within an advanced Enhanced Recovery After Surgery (ERAS) program.

METHODS

A retrospective analysis of prospectively collected data was conducted. Characteristics, perioperative and outcome data, compliance with ERAS pathways and a home-transition QOR survey were analysed using a multivariable logistic regression model.

RESULTS

From January 2020 to January 2022, a total of 201 consecutive patients underwent subxiphoid multiportal thoracoscopic anatomical lung resection, comprising 108 lobectomies and 93 sublobar resections (SLRs) (59 complex SLRs and 34 simple SLRs). Among them, 113 patients (56%) were discharged on POD 1, 49% after a lobectomy, 59% after a simple sublobar resection and 68% after a complex sublobar resection. In the multivariable analysis, age > 74 years and duration of the operation were associated with discharge after POD 1, whereas forced expiratory volume in 1 s and complex SLRs were associated with discharge on POD 1. Chest tube removal was achieved on POD 0 in 58 patients (29%), and 138 patients (69%) were free from a chest tube on POD 1. There were 13% with in-hospital morbidity, 10% with 90-day readmission (7% after POD 1 discharge and 14% in patients discharged after POD 1), and 0.5% with 90-day mortality. Patients discharged on POD 1 showed better compliance with the ERAS pathway with early chest tube removal and opioid-free analgesia. The home-transition QOR survey reported a better experience of returning home after discharge on POD 1 and similar pain scores.

CONCLUSIONS

Postoperative day 1 discharge can be safely achieved in appropriately selected patients after subxiphoid thoracoscopic anatomical lung resection, with excellent outcomes and high quality of recovery, supported by early chest tube removal as a determinant ERAS pathway.

Randomized Controlled Trial of Thresholds for Drain Removal After Anatomic Lung Resection

BACKGROUND

The criteria for chest drain removal after lung resections remain vague and rely on personal experience instead of evidence. Because pleural fluid resorption is proportional to body weight, a weight-related approach seems reasonable. We examined the feasibility of a weight-adjusted fluid output threshold concerning postoperative respiratory complications and the occurrence of symptomatic pleural effusion after chest drain removal. Our secondary objectives were the hospital length of stay and pain levels before and after chest drain removal.

METHODS

This was a single-center randomized controlled trial including 337 patients planned for open or thoracoscopic anatomical lung resections. Patients were randomly assigned postoperatively into 2 groups. The chest drain was removed in the study group according to a fluid output threshold calculated by the 5 mL × body weight (in kg)/24 hours formula. In the control group, our previous traditional fluid threshold of 200 mL/24 hours was applied.

RESULTS

No differences were evident regarding the occurrence of pleural effusion and dyspnea at discharge and 30 days postoperatively. In the logistic regression analysis, the surgical modality was a risk factor for other complications, and age was the only variable influencing postoperative dyspnea. Time to chest drain removal was identical in both groups, and time to discharge was shorter after open surgery in the test group.

CONCLUSIONS

No increased postoperative complications occurred with this weight-based formula, and a trend toward earlier discharge after open surgery was observed in the test group.

Feasibility of utilizing mediastinal drains alone following esophageal cancer surgery: a retrospective study

BACKGROUND

It was typically necessary to place a closed thoracic drainage tube for drainage following esophageal cancer surgery. Recently, the extra use of thoracic mediastinal drainage after esophageal cancer surgery had also become more common. However, it had not yet been determined whether mediastinal drains could be used alone following esophageal cancer surgery.

METHODS

A total of 134 patients who underwent esophageal cancer surgery in our department between June 2020 and June 2023 were retrospectively analyzed. Among them, 34 patients received closed thoracic drainage (CTD), 58 patients received closed thoracic drainage combined with mediastinal drainage (CTD-MD), while 42 patients received postoperative mediastinal drainage (MD). The general condition, incidence of postoperative pulmonary complications, postoperative NRS score, and postoperative anastomotic leakage were compared. The Mann-Whitney U tests, Welch's t tests, one-way ANOVA, chi-square tests and Fisher's exact tests were applied.

RESULTS

There was no significant difference in the incidence of postoperative hyperthermia, peak leukocytes, total drainage, hospitalization days and postoperative pulmonary complications between MD group and the other two groups. Interestingly, patients in the MD group experienced significantly lower postoperative pain compared to the other two groups. Additionally, abnormal postoperative drainage fluid could be detected early in this group. Furthermore, there was no significant change in the incidence of postoperative anastomotic leakage and the mortality rate of patients after the occurrence of anastomotic leakage in the MD group compared with the other two groups.

CONCLUSIONS

Using mediastinal drain alone following esophageal cancer surgery was equally safe. Furthermore, it could substantially decrease postoperative pain, potentially replacing the closed thoracic drain in clinical practice.

Effectiveness of Stitch With Pledget to Prevent Prolonged Air Leak in Thoracoscopic Lung Resection

INTRODUCTION

We previously demonstrated the usefulness of combining stitching with covering to seal alveolar air leaks in an animal model. This study aimed to clarify the effectiveness and feasibility of this sealing method in the clinical setting.

METHODS

Data of 493 patients who underwent thoracoscopic anatomical resection between 2013 and 2020 for lung cancer were retrospectively reviewed. Prolonged air leak was defined as chest drain placement lasting 5 d or longer due to air leak. Until July 2017 (early study period), we covered air leaks using mesh. However, for sealing (late study period), we additionally stitched leaks with pledget in patients at high risk of prolonged air leak. The pneumostasis procedure, intraoperative confirmation test of pneumostasis, and chest tube management were uniform during both periods.

RESULTS

The incidence of prolonged air leak was significantly lower in the late than in the early period (3.6% versus 12.5%), whereas pulmonary emphysema was more severe in the late period compared to the early period. Intraoperative failure of sealing air leaks was significantly reduced in the late period than in the early period. In both univariate and propensity score matching analysis, the study period was a significant predictor of prolonged air leak.

CONCLUSIONS

The combination of stitching and covering with mesh may contribute to reducing prolonged air leak incidence in patients undergoing thoracoscopic anatomical lung resection for lung cancer.

Zero-leak prediction during major lung resection aiming for minimal chest drainage duration: a retrospective analysis

BACKGROUND

Early chest tube removal should be considered to enhance recovery after surgery. The current study aimed to provide a predictive algorithm for air leak episodes (ALE) and to create a knowledge base for early chest tube removal.

METHODS

This retrospective study enrolled patients who underwent thoracoscopic anatomical pulmonary resections in our unit. We defined ALE as any airflow ≥ 10 mL/min recorded in the follow-up charts based on the digital thoracic drainage device. Multivariate regression analysis was used to control for preoperative and intraoperative confounding factors. The ALE prediction algorithm was constructed by combining an additive ALE risk-scoring system using the coefficients of the significant predictive factors with the intraoperative water-sealing test.

RESULTS

In 485 consecutive thoracoscopic major pulmonary resections, ALE developed in 209 (43%) patients. Statistically significant ALE-associated preoperative factors included male sex, lower body mass index, radiologically evident emphysema, lobectomy, and upper lobe surgery. Significant ALE-associated intraoperative factors were incomplete fissure and pleural adhesion. The ALE risk scoring demonstrated an average area under the receiver operating characteristic curve of 0.72 in the fivefold cross-validation test. The ALE prediction algorithm correctly predicted ALE-absent patients at a negative predictive value of 80%.

CONCLUSIONS

The algorithm may promote the optimization of the chest tube-dwelling duration by identifying potential ALE-absent patients for accelerated tube removal.

Efficacy of avoiding chest drains after video-assisted thoracoscopic surgery wedge resection: protocol for a randomised controlled trial

INTRODUCTION

The use of routine postoperative chest drains after video-assisted thoracoscopic surgery (VATS) of the lung is a practice based on tradition with the aim of draining fluid and air. However, new evidence suggests that chest drains can be avoided in selected cases. With this randomised controlled trial, we wish to establish the efficacy and safety of avoiding postoperative chest drains compared with routine postoperative chest drains.

METHODS AND ANALYSIS

This is a two-centre randomised controlled trial without allocation concealment, but where randomisation occurs after the end of procedure leaving operative personnel blinded during surgery. The sample size is calculated to show a difference in pain measurements using the Numeric Rating Scale under different circumstances and at different time points to show superiority of the intervention. The trial is pragmatic by design to reflect the daily clinical scenario and with the aim of increasing the external validity of the results.

ETHICS AND DISSEMINATION

Approval by the local ethics committees has been obtained for both sites. The study was registered with ClinicalTrials.gov (NCT05358158) prior to inclusion. The results of the trial will be disseminated by publication in an international journal and presentation at major international thoracic surgical meetings.

ARTICLE SUMMARY

This is a randomised controlled trial estimating the effects of avoiding a chest drain after VATS wedge resection of the lung on pain, total morphine use, quality of life and complications.

Chest drains after open paediatric lung resections: not always required

INTRODUCTION

Chest drains are often a great source of pain and anxiety in paediatric patients. While there is growing evidence to support the selective omission of chest drains after thorascopic lung resection in children, the safety of this practice following open lung resection has yet to be evaluated. Chest drains are not routinely placed at our institution. We therefore aimed to describe our experience of selective chest drain placement in children undergoing open lung resection, and report the safety and complication profile of this practice.

METHODS

Retrospective review of all open lung resections performed at Wellington Regional Hospital, in children < 16 years of age, from June 2009 to June 2022. Clinical, radiological and operative outcomes were identified and analyzed. The cohort was divided into two groups - those that had a chest drain placed intraoperatively, and those that did not.

RESULTS

35 children underwent open lung resection over the study period. The mean operative age was 8.0 ± 5.4 months, with the most common resection being a lobectomy (80%). Eight children (23%) did not have a chest drain placed, whereas the remaining 29 children (77%) had at least one drain placed intraoperatively, with a median drainage time of 3.0 days. Length of stay was significantly shorter in children who did not have a chest drain placed intraoperatively, compared to those that did (2.5 vs. 5.0 days, p = 0.019). There were no significant differences observed in complication or reintervention rates between the two groups. Similarly, there were no significant differences in the incidence of a residual pneumothorax or effusion on the pre-discharge CXR between the groups.

CONCLUSIONS

Chest drains may not always be required following open paediatric lung resection. The selective omission of a chest drain following open lung resection, does not appear to result in a significantly higher rate of complications or reintervention, and is associated with significantly shorter hospital length of stay.

Analyzing robotic surgery impact on recovery quality & emotions

Background

The objective of this study is to investigate the postoperative recovery quality and emotional status of patients with non-small cell lung cancer (NSCLC) who underwent robot-assisted and video-assisted thoracoscopic surgery using the 15-item Quality of Recovery (QoR-15) scale and to analyze the correlation.

Methods

We collected clinical data from 320 patients with NSCLC who underwent lobectomy using either robot-assisted thoracoscopic surgery (RATS) or video-assisted thoracoscopic surgery (VATS) at our center from January 2021 to December 2022. We compared perioperative parameters and followed up after the operation using the QoR-15 scale to objectively assess the quality of postoperative recovery and physical and emotional status.

Results

Apart from a notable distinction in anesthesia time, no significant differences were observed in other general data. Notably, the overall recovery rate for patients in the RATS group surpassed that of the VATS group (P < 0.05). Specifically, the recovery rates in the RATS group were significantly superior to those in the VATS group across nociceptive factors, emotional factors, activities of daily living, physiological factors, and cognitive ability (P < 0.05). Spearman correlation analysis between surgical methods and various indicators of the QoR-15 scale showed significant correlations between surgical methods (P < 0.05).

Conclusion

The QoR-15 scale is a valuable tool for assessing the postoperative recovery quality in lung cancer patients. The RATS plays a significant role in promoting the swift postoperative recovery of patients and demonstrates excellent efficacy, safety, and reliability.

A chest tube after robotic thymectomy is unnecessary

Objective

Chest tubes are frequently placed after thymectomy, without data to support this common practice. We report our experience in eliminating them after robotic thymectomy.

Methods

This is a retrospective database review of patients who underwent robotic thymectomy performed by a single surgeon in which intraoperative chest tube insertion was not planned. Patient characteristics and postoperative outcomes are presented.

Results

Between January 2018 and October 2022, 75 patients underwent robotic thymectomy performed by a single surgeon. Of those, 64 (85.3%) underwent a left-sided thoracic approach. The most common indication for resection was a suspicious anterior mediastinal mass. There were no conversions to an open operation. The median operative time was 72 minutes (range, 38-164 minutes), and the median estimated blood loss was 20 cc (range, 10-60 cc). Ten patients (13.3%) went home on the day of surgery, and all others (86.7%) were discharged on postoperative day 1. A chest tube was placed in 1 patient at time of closure because of a persistent air leak after extensive adhesiolysis from a prior thoracotomy; the tube was removed on the day of surgery after resolution of the air leak. No other patient required chest tube placement intraoperatively, immediately postoperatively, or within 60 days postoperation. Two patients underwent outpatient thoracentesis within 1 month postoperation for effusions. There were no 30- or 90-day mortality and no major morbidities.

Conclusions

A chest tube after robotic thymectomy is not necessary in almost all patients and can be safely omitted. The dogmatic routine practice of chest tube placement should be questioned.

Are chest drains routinely required after thoracic surgery? A drainology study of on-table chest-drain removals

Objectives

Advances in perioperative management for thoracic surgery have accelerated the postoperative recovery of patients by decreasing postoperative pain and the incidence of complications. We aimed to study whether it's safe to remove chest drains on table in selected cases.

Methods

This was a 5-year retrospective analysis of protocolized chest-drain removal on the operating table. The chest drain was removed in patients undergoing sublobar/wedge lung resection and other minor thoracic procedure (pleural biopsy, mediastinal mass biopsy/resection) via a thoracoscopic approach (video-assisted thoracoscopic surgery). Chest drains were removed at the end of the operation if air leak as documented by the digital drain was less than 20 mL/min. Outcome data on postdrain removal pneumothorax, effusion, and need for further intervention were obtained by reviewing the postoperative chest films, all reported by a radiologist.

Results

Between 2016 and 2021, 107 patients underwent drain removal in theater. Mean age (standard deviation) was 58 (17) years and 54 (50.5%) were male. Postdrain removal pneumothorax occurred in 22 patients (21%), pleural effusion in 6 (5.6%), and 21 of 22 postoperative pneumothoraces were managed conservatively without reinsertion of chest drain. As it is our standard policy to leave no pneumothorax in patients undergoing surgical management of primary spontaneous pneumothorax, only 1 such patient (0.9%) had a drain reinserted as a result. The median (interquartile) length of hospital stay was 1 day (1-2), and 14 patients (13%) were discharged on surgery day.

Conclusions

Our results demonstrate that on table chest-drain removal in selected cases is safe and repeatable using a digital drain, challenging the practice of routine drain insertion after thoracic surgery.

Unnecessity of routine chest tube drainage after patent ductus arteriosus ligation in preterm neonates

BACKGROUND

Conventionally, a chest tube drainage is placed following patent ductus arteriosus (PDA) ligation to monitor possible bleeding and drain air or effusion postoperatively. However, the necessity of chest tube drainage after thoracotomy in PDA ligation is controversial. We evaluated the feasibility and safety of omitting chest tube drainage in preterm neonates who underwent PDA ligation via thoracotomy.

METHODS

We retrospectively reviewed the medical records of 56 preterm neonates who underwent surgical ligation of PDA via thoracotomy in the neonatal intensive care unit between January 2014 and March 2022.

RESULTS

The median gestational age was 26.9 (interquartile range [IQR]: 25.9-28.8) weeks and the median body weight at birth was 895 (IQR: 795-1190) g. The median age on the day of surgery was 17.0 (IQR: 10.0-22.0) days and the median body weight on the day of surgery was 1100 (IQR: 958-1410) g. The median operative time was 44.5 (IQR: 35.5-54.0) minutes. There were no intraoperative events or procedure-related deaths. On postoperative chest radiographs, no patients had major complications, such as pneumothorax or hemothorax. Nineteen patients (34%) had minor complications of subcutaneous emphysema around the thoracotomy site. No patients required additional chest tube drainage for postoperative bleeding, pleural effusion, or progressive subcutaneous emphysema. No patients had surgical wound infections. There were seven in-hospital mortalities, which were unrelated to the surgery.

CONCLUSIONS

Omitting chest tube drainage is feasible and safe for the postoperative management of preterm neonates undergoing PDA ligation via thoracotomy.

Achieving opioid-free discharge following robotic thoracic surgery: A single-institution experience

Objectives

Enhanced recovery after thoracic surgery (ERATS) protocols use a combination of analgesics for pain control and have been associated with decreased opioid requirements. We investigated the impact of continual ERATS refinement on the incidence of opioid-free discharge.

Methods

We retrospectively analyzed our prospectively maintained institutional database for elective, opioid-naive robotic thoracoscopic procedures. Demographics, operative outcomes, postoperative opioid dispensed (morphine milligram equivalent), and opioid discharge status were collected. Our primary outcome of interest was factors associated with opioid-free discharge; our secondary objective was to determine the incidence of new persistent opioid users.

Results

In total, 466 patients from our optimized ERATS protocol were included; 309 (66%) were discharged without opioids. However, 34 (11%) of patients discharged without opioids required a prescription postdischarge. Conversely, 7 of 157 patients (11%), never filled their opioid prescriptions given at discharge. Factors associated with opioid-free discharges were nonanatomic resections, mediastinal procedures, minimal pain, and lack of opioid usage on the day of discharge. More importantly, 3.2% of opioid-free discharge patients became new persistent opioid users versus 10.8% of patients filling opioid prescriptions after discharges (P = .0013). Finally, only 2.3% of opioid-naive patients of the entire cohort became chronic opioid users; there was no difference in the incidence of chronic use by opioid discharge status.

Conclusions

Optimized opioid-sparing ERATS protocols are highly effective in reducing opioid prescription on the day of discharge. We observed a very low rate of new persistent or chronic opioid use in our cohort, further highlighting the role ERATS protocols in combating the opioid epidemic.

Drainless robot-assisted minimally invasive oesophagectomy-randomized controlled trial (RESPECT)

BACKGROUND

The purpose of this randomized trial is to evaluate the early removal of postoperative drains after robot-assisted minimally invasive oesophagectomy (RAMIE). Evidence is lacking about feasibility, associated pain, recovery, and morbidity.

METHODS/DESIGN

This is a randomized controlled multicentric trial involving 72 patients undergoing RAMIE. Patients will be allocated into two groups. The "intervention" group consists of 36 patients. In this group, abdominal and chest drains are removed 3 h after the end of surgery in the absence of contraindications. The control group consists of 36 patients with conventional chest drain management. These drains are removed during the further postoperative course according to a standard algorithm. The primary objective is to investigate whether postoperative pain measured by NRS on the second postoperative day can be significantly reduced in the intervention group. Secondary endpoints are the intensity of pain during the first week, analgesic use, number of postoperative chest X-ray and CT scans, interventions, postoperative mobilization (steps per day as measured with an activity tracker), postoperative morbidity and mortality.

DISCUSSION

Until now, there have been no trials investigating different intraoperative chest drain strategies in patients undergoing RAMIE for oesophageal cancer with regard to perioperative complications until discharge. Minimally invasive approaches combined with enhanced recovery after surgery (ERAS) protocols lower morbidity but still include the insertion of chest drains. Reduction and early removal have been proposed after pulmonary surgery but not after RAMIE. The study concept is based on our own experience and the promising current results of the RAMIE procedure. Therefore, the presented randomized controlled trial will provide statistical evidence of the effectiveness and feasibility of the "drainless" RAMIE.

Efficacy and safety of early chest tube removal after selective pulmonary resection with high-output drainage: A systematic review and meta-analysis

BACKGROUND

There is controversy over the drainage threshold for removal of chest tubes in the absence of significant air leakage after selective pulmonary resection.

METHODS

A comprehensive search of online databases (PubMed, Web of Science, Embase, Cochrane Library, Scopus, Ovid, Elsevier, Ebsco, and Wiley) and clinical trial registries (WHO-ICTRP and ClinicalTrials.gov) was performed to investigate the efficacy and safety of early chest tube removal with high-output drainage. Primary outcome (postoperative hospital day) and secondary outcomes (30-day complications, rate of thoracentesis, and chest tube placement) were extracted and synthesized. Subgroup analysis, meta-regression, and sensitivity analysis were used to explore the potential heterogeneity. Study quality was assessed with the Newcastle-Ottawa Scale, and evidence was graded using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) assessment by the online GRADEpro Guideline Development Tool.

RESULTS

Six cohort studies with a total of 1262 patients were included in the final analysis. The postoperative hospital stay in the high-output group was significantly shorter than in the conventional treatment group (weighted mean difference: -1.34 [-2.34 to -0.34] day, P = .009). While there was no significant difference between 2 groups in 30-day complications (relative ratio [RR]: 0.92 [0.77-1.11], P = .38), the rate of thoracentesis (RR: 1.93 [0.63-5.88], P = .25) and the rate of chest tube placement (RR: 1.00 [0.37-2.70], P = .99). According to the sensitivity analysis, the relative impacts of the 2 groups had already stabilized. Subgroup analysis revealed that postoperative hospital stay was modified by Newcastle-Ottawa Scale score. The online GRADEpro Guideline Development Tool presented very low quality of evidence for the available data.

CONCLUSIONS

This meta-analysis revealed that it is feasible and safe to remove a chest tube with high-output drainage after pulmonary resection for selected patients.

Early Water Seal of Chest Tubes Following Video-Assisted Thoracic Surgery Pleurodesis

INTRODUCTION

Early water seal following minimally invasive pulmonary lobectomy has been shown to reduce chest tube duration and postoperative length of stay (LOS). We evaluated chest tube duration and postoperative LOS following a standardized chest tube management protocol change (water seal on postoperative day 1) after video-assisted thoracic surgery (VATS) pleurodesis.

METHODS

We identified adult patients undergoing VATS pleurodesis from August 2013 to December 2021. The chest tube protocol was changed in January 2017 such that patients were placed to water seal on the morning of postoperative day 1. Patients were divided into two groups, before the change (Group 1: August 2013-December 2016) and after (Group 2: January 2017-December 2021). We compared demographics, clinical characteristics, operative details, postoperative chest tube duration and output, and postoperative LOS between the groups. Descriptive statistics and log-transformed multivariable linear regression models were used to identify differences in patient outcomes that were associated with the protocol change.

RESULTS

A total of 488 patients underwent VATS pleurodesis during the study period (Group 1: 329 patients; Group 2: 159 patients). The median age was 61 y (interquartile range [IQR] 49-68), 51% were females, 69% were White, and 29% were Black. For postoperative LOS, Group 1 had an IQR of 3-7 d, while Group 2 had an IQR of 2-6 d (P < 0.001). The multivariable log-transformed linear regression models demonstrated that the practice change was associated with reduced chest tube duration (0.77 times the chest tube duration before the change; P < 0.001) and reduced LOS (0.81 times the LOS before the change; P = 0.006). There was an associated reduction in patients needing to return to the operating room (P = 0.048) and needing postoperative extended ventilatory support (P = 0.035).

CONCLUSIONS

Development of a standardized protocol to water seal chest tubes on postoperative day 1 following VATS pleurodesis is associated with reduced chest tube duration and LOS without an increase in postoperative complication rates.

Use of rocuronium and sugammadex for video-assisted thoracoscopic surgery is associated with reduced duration of chest tube drainage: a propensity score-matched analysis

BACKGROUND

We investigated the influence of different neuromuscular blocking agents and reversal agents during anaesthesia on early removal of chest tube drainage after video-assisted thoracoscopic surgery (VATS).

METHODS

This retrospective single-centre study included patients who underwent VATS after tracheal intubation under general anaesthesia. Patients received either cisatracurium and neostigmine (n=547) or rocuronium and sugammadex (n=151). Quantitative neuromuscular monitoring was used and one chest tube (size 24 Fr) was inserted. To reduce potential bias, 140 patients from each group were matched by propensity score for sex, age, body mass index and indication for VATS. Primary outcome was duration of chest tube drainage after surgery.

RESULTS

Use of rocuronium and sugammadex was associated with a shorter duration of chest tube drainage (2 [1-2] vs 2 [1-3] days; P=0.049) and a 63% reduction in delayed chest tube removal (odds ratio 0.37; 95% confidence interval [CI]: 0.20-0.67; P=0.005). This group also had a lower incidence of postoperative atelectasis (P=0.047) and consolidation (P=0.008). Each 1 h increase in the duration of anaesthesia was associated with a 1.57-fold increase in the delayed removal of the chest tube (95% CI: 1.25-1.96; P=0.005).

CONCLUSIONS

During general anaesthesia for VATS, compared with cisatracurium and neostigmine, use of rocuronium and sugammadex was associated with a significant decrease in the incidence of postoperative delayed removal of the chest tube, atelectasis, and pulmonary consolidation.

Chest Tube Management: Past, Present, and Future Directions for Developing Evidence-Based Best Practices

In the field of modern cardiothoracic surgery, chest drainage has become ubiquitous and yet characterized by a wide variation in practice. Meanwhile, the evolution of chest drain technology has created gaps in knowledge that represent opportunities for new research to support the development of best practices in chest drain management. The chest drain is an indispensable tool in the recovery of the cardiac surgery patient. However, decisions about chest drain management-including those about type, material, number, maintenance of patency, and the timing of removal-are largely driven by tradition due to a scarcity of quality evidence. This narrative review surveys the available evidence regarding chest-drain management practices with the objective of highlighting scientific gaps, unmet needs, and opportunities for further research.

A novel drainage strategy using chest tube plus pleural catheter in uniportal upper lobectomy: A randomized controlled trial

BACKGROUND

In this study we explored whether one pleural catheter plus single chest tube drainage could achieve a noninferior drainage effect when compared with the traditional two chest tubes in uniportal video-assisted thoracoscopic surgery (VATS) for an upper pulmonary lobectomy.

METHODS

Patients that underwent an upper pulmonary lobectomy from January to November 2020 were enrolled in this single-center, randomized, open-label, noninferiority trial. Prior to closure, patients were randomized to an intervention group who received an improved drainage strategy involving one pleural catheter with one chest tube (24 Fr), while traditional double chest tube drainage was applied for the control group.

RESULTS

A total of 390 patients entered the study, although 190 were excluded for changing nonuniportal surgical approaches or opting for nonlobectomy resections. Finally, 200 patients were randomized (100 in the intervention group and 100 in the control group). The baseline demographic and clinical characteristics were comparable between the groups. The incidence of pneumothorax in the intervention and control groups was similar on postoperative Day 1 (noninferiority, 10% vs. 13%, p = 0.658). In addition, there were no significant differences in secondary outcomes such as incidence of pneumothorax by Day 30, postoperative chest tube/pleural catheter removal time, amount of drainage on Day 1, total amount of drainage after operation, or postoperative hospitalization. A significantly lower pain score was observed in the intervention group (3.33 ± 0.68 vs. 3.68 ± 0.94, p = 0.003).

CONCLUSIONS

The new strategy is noninferior to double chest tube drainage after an upper pulmonary lobectomy offers superior pain control, and is recommended for an upper lobectomy by uniportal VATS.

Multimodal Pain Management Protocol to Decrease Opioid Use and to Improve Pain Control After Thoracic Surgery

BACKGROUND

Opioid addiction continues to be a devastating problem in our communities, and up to 40% of patients begin their addiction with legally prescribed opioids after injury or surgical procedure. An opioid-free multimodal pain regimen was developed with the goal of decreasing opioid exposure while maintaining adequate pain control.

METHODS

A retrospective single-institution study was conducted of 313 consecutive patients undergoing minimally invasive lobectomy before (n = 211) and after (n = 102) implementation of an opioid-free protocol from 2016 to 2020. Data analysis was conducted on preoperative characteristics, postoperative opioid use at set time points (postoperative day 0, postoperative days 1 to 7, and total stay), pain scores, discharge with opioid prescription, and postoperative outcomes.

RESULTS

Patients on the opioid-free protocol had significantly lower average total morphine milligram equivalents at all time points. In addition, 56% of patients in the opioid-free group received no oral opioids at all, and 91% did not receive a patient-controlled analgesia pump. Average pain scores were significantly lower in the opioid-free protocol patients along with percentage of time spent with pain scores <3 and <6. With implementation of the protocol, 62% of patients are discharged without an opioid prescription compared with only 7% previously.

CONCLUSIONS

Implementation of an opioid-free protocol led to a significant decrease in the use of postoperative opioids at all time points while improving overall management of pain. In addition, most patients are discharged with no home opioid prescription, decreasing a potential source of community opioid spread.

Making a Painless Drain: Proof of Concept

Chest tubes account for a large proportion of postoperative pain after cardiothoracic operations. The objective of this study was to develop a novel, cost-effective, easy-to-use, lidocaine-eluting coating to reduce pain associated with postoperative chest tubes. A lidocaine-eluting hydrogel was developed by dispersing lidocaine-loaded nanoparticles in an aqueous solution containing gelatin (5%). Glutaraldehyde (1%) was added to crosslink the gelatin into a hydrogel. The hydrogel was dehydrated, resulting in a thin, stable polymer. Sterile lidocaine hydrogel-coated silicone discs and control discs were prepared and surgically implanted in the subcutaneous space of C57B6 mice. Using von Frey filaments, mice underwent preoperative baseline pain testing, followed by pain testing on post-procedure day 1 and 3. On post-procedure day 1, mice implanted with control discs demonstrated no change in pain tolerance compared to baseline, while mice implanted with 20 mg and 80 mg lidocaine-loaded discs demonstrated a 2.4-fold (P = 0.36) and 4.7-fold (P = 0.01) increase in pain tolerance, respectively. On post-procedure day 3, mice implanted with control discs demonstrated a 0.7-fold decrease in pain tolerance compared to baseline, while mice implanted with 20 mg and 80 mg lidocaine-loaded discs demonstrated a 1.8-fold (P = 0.88) and 8.4-fold (P = 0.02) increase in pain tolerance, respectively. Our results demonstrate successful development of a lidocaine-eluting chest tube with hydrogel coating, leading to improved pain tolerance in vivo. The concept of a drug-eluting drain coating has significant importance due to its potential universal application in a variety of drain types and insertion locations.

Management von Thoraxdrainagen nach elektiven, thorakoskopischen, anatomischen Lungenresektionen an thoraxchirurgischen Zentren in Deutschland . Eine Umfrage über die Deutsche Gesellschaft für Thoraxchirurgie (DGT)

Einleitung Die zunehmende Adaptation minimalinvasiver Techniken sowie der Prinzipien der „Enhanced Recovery After Surgery“ (ERAS) in der Thoraxchirurgie haben zu einer deutlichen Reduktion des perioperativen Risikos nach anatomischen Lungenresektionen geführt. Die persistierende postoperative Luftleckage bleibt allerdings weiterhin eine der Hauptkomplikationen. Ziel dieser Umfrage war es, das Management von Thoraxdrainagen sowie die klinische Praxis der Behandlung persistierender Luftleckagen nach elektiven, thorakoskopischen, anatomischen Lungenresektionen in Deutschland zu analysieren.

Methodik Wir führten über die Deutsche Gesellschaft für Thoraxchirurgie (DGT) eine Online-Umfrage unter thoraxchirurgischen Zentren (n = 160) in Deutschland durch. Die Ergebnisse wurden getrennt nach High-Volume- und Low-Volume-Zentren ausgewertet.

Ergebnisse Die Rücklaufquote betrug 35,6%. Die Mehrheit der Kliniken verwendet als Standard eine einzelne Thoraxdrainage (24 Ch), die an ein digitales Thoraxdrainagesystem unter Sog angeschlossen wird. Eine postoperative Luftleckage wird von 42,1% der Kliniken nach dem 7. postoperativen Tag behandelt. Die Luftleckage wird von der Mehrheit entweder durch eine Reduktion des Sogs oder durch andere konservative Maßnahmen behandelt. Es zeigte sich kein signifikanter Unterschied im Drainagemanagement zwischen High-Volume- und Low-Volume-Zentren.

Schlussfolgerung Die Krankenhausverweildauer nach einer unkomplizierten Lobektomie beträgt heute im Regelfall nur wenige Tage, wobei die untere Grenzverweildauer bei 2 Tagen liegt. Dennoch definieren über 80% der deutschen Zentren eine Luftleckage erst dann als prolongiert, wenn sie nach dem 5. postoperativen Tag besteht; 65% behandeln sie auch erst dann. Die Studienlage hierzu ist nicht richtungsweisend. Weitere prospektive klinische Studien sind nötig, um die Behandlung der häufigsten Komplikation nach Lungenresektionen zu verbessern.

Spontaneous ventilation anesthesia combined with uniportal and tubeless thoracoscopic sympathectomy in selected patients with primary palmar hyperhidrosis

Background

To assess the feasibility and safety of tubeless video-assisted thoracoscopic sympathectomy (VATS) with a single 5 mm port under nonintubated, intravenous anesthesia with spontaneous ventilation in selected patients with primary palmar hyperhidrosis (PPH).

Methods

Adults (aged between 18 and 60 years) with moderate or severe PPH symptoms were enrolled. Demographic information and clinical data were obtained from 172 consecutive patients undergoing thoracoscopic surgery for PPH from March 2014 to December 2020. The primary outcomes were the rate of complications, including death, and the intraoperative conversion rate to 3-port VATS. The secondary outcomes were the conversion rate to intubated anesthesia during the operation and the surgical duration and pain score of postoperative day 0.

Results

In total, 172 patients were included with 88 males and 84 females. The median age was was 25 years (IQR:21–30 years). No mortalities or major morbidities occurred in any patient. The overall median surgical duration was 53 min (IQR:37–72 min). The median length of postoperative hospital stay was one day (IQR:one–one day). The median pain score of POD0 was 2 (IQR:2–2). Intraoperative conversion to 3-port VATS followed by drainage tube insertion occurred in one (0.6%) patient due to extensive pleural adhesions. No patients required conversion to intubated anesthesia during surgery. No postoperative mechanical ventilation was noted in any patient.

Conclusions

For selected patients with PPH, tubeless VATS with a single 5 mm port using spontaneous ventilation anesthesia can be considered a feasible and safe operation. The surgical wound is extremely small and the operation time is shorter than the conventional technique.

Trial registration This study was in conformity with the Declaration of Helsinki, and was approved by the National Ethics Committee of the University of the Hong Kong-Shenzhen Hospital (Approval number: [2020]70). We registered the study in the Chinese Clinical Trial Registry (Registration number: ChiCTR2100049063) in 2021.Informed consent was collected from all the participants of this study.

A propensity sore-matched study: Applying a modified chest tube drainage strategy in rapid rehabilitation following uni-portal thoracoscopic pulmonary wedge resection

PURPOSE

This study aimed to compare the value of a modified chest tube drainage strategy to a traditional drainage strategy in single-port thoracoscopic pulmonary wedge resection.

METHODS

From January 2019 to July 2021, we collected clinical data on 405 patients who underwent single-port thoracoscopic pulmonary wedge resection in the No.1 Department of Thoracic Surgery at Fujian Medical University Union Hospital, with 121 (29.9%) cases in the modified drainage strategy group and 284 (70.1%) cases in the traditional drainage strategy group. The propensity score matching method (Match Ratio = 1:1) was used to reduce differences in clinical characteristics between the two groups.

RESULTS

Following 1:1 propensity score matching, 120 matched pairs (240 patients) were included in the study. There was no significant difference in general clinical characteristics between the two groups. There was no statistical difference in intraoperative factors except for operative times (71.42 ± 22.98 min vs. 86.80 ± 36.75 min, p < 0.001). In terms of postoperative factors, there were significant differences in postoperative chest tube duration (0.00 ± 0.00 h vs. 32.68 ± 18.51 h, p < 0.001), total drainage volume (143.03 ± 118.33 ml vs. 187.73 ± 140.82 ml, p = 0.008), postoperative hospital stay (2.61 ± 0.70 days vs. 3.27 ± 1.88 days, p < 0.001), number of additional pain relief (0.14 ± 0.40 vs. 0.42 ± 0.74, p < 0.001), facial pain score (2.7 ± 1.8 vs. 3.6 ± 2.7, p = 0.005) and adverse events (p = 0.046). Furthermore, there was a statistical difference between the two groups regarding CTCAE grade-1 complication, but no statistical difference in CTCAE grade-2 complication.

CONCLUSIONS

A modified drainage strategy in single-port thoracoscopic pulmonary wedge resection is safe and feasible, allowing for less postoperative rehabilitation time, pain relief, reduced postoperative pleural effusion, and reduced clinical workload.

Regional Analgesia in Video-Assisted Thoracic Surgery: A Bayesian Network Meta-Analysis

Background

A variety of regional analgesia methods are used during video-assisted thoracic surgery (VATS). Our network meta-analysis (NMA) sought to evaluate the advantages of various methods of localized postoperative pain management in VATS patients.

Methods

PubMed, the Cochrane Library, and EMBASE were searched from their date of inception to May 2021 for randomized controlled trials (RCTs) comparing two or more types of locoregional analgesia in adults using any standardized clinical criteria. This was done using Bayesian NMA.

Results

A total of 3,563 studies were initially identified, and 16 RCTs with a total of 1,144 participants were ultimately included. These studies, which spanned the years 2014 to 2021 and included data from eight different countries, presented new information. There were a variety of regional analgesia techniques used, and in terms of analgesic effect, thoracic epidural anesthesia (TEA) [SMD (standard mean difference) = 1.12, CrI (Credible interval): (-0.08 to -2.33)], thoracic paravertebral block (TPVB) (SMD = 0.67, CrI: (-0.25 to 1.60) and erector spinae plane block (ESPB) (SMD = 0.34, CrI: (-0.5 to 1.17) were better than other regional analgesia methods.

Conclusion

Overall, these findings show that TEA, TPVB and ESPB may be effective forms of regional analgesia in VATS. This research could be a valuable resource for future efforts regarding the use of thoracic regional analgesia and enhanced recovery after surgery.

Comparison between intrathecal morphine and intravenous patient control analgesia for pain control after video-assisted thoracoscopic surgery: A pilot randomized controlled study

Background

Video-assisted thoracoscopic surgery (VATS) is a minimally invasive procedure, but patients may still experience intense pain, especially during the early postoperative period. Intrathecal morphine (ITM) is an effective pain control method that involves a simple maneuver and has a low risk of complications. This study aimed to study the effectiveness of ITM for pain control in patients who undergo VATS.

Materials and methods

A randomized controlled study was conducted who were in ASA classes 1–3, aged over 18 years, and scheduled for elective VATS. Patients were randomized into two groups: the ITM group (n = 19) received a single shot of 0.2 mg ITM before general anesthesia; and the control group (n = 19) received general anesthesia only. For 48 hours after surgery, other than intravenous patient-controlled analgesia (IVPCA) morphine, patients received no sedatives or opioid medications except for 500 mg acetaminophen four times daily orally. Postoperative pain scores and IVPCA morphine used, side effects, sedation at specific time-points, i.e., 1, 6, 12, 24, and 48-hours and overall treatment satisfaction scores were assessed.

Results

Postoperative pain scores (median [IQR]) in ITM group were significantly lower than control group (repeated-measure ANOVA, p = 0.006) and differed at the first (7 [2, 7] vs 8 [6, 9], p = 0.007) and sixth hours (3 [2, 5] vs 5 [5, 7], p = 0.002). The cumulative dose of post-operative morphine (median [IQR]) in ITM group was also lower (6 [3, 20] vs 19 [14, 28], p = 0.006). The incidence of pruritus was significantly higher in ITM group (68.42% vs. 26.32%, p = 0.009). No significant differences in nausea and vomiting, sedation scores, and satisfaction scores were observed between the two groups.

Conclusion

ITM could reduce pain scores and opioid consumption after VATS compared to IVPCA-opioids. However, pain scores and opioid consumption still remained high. No difference in patient satisfaction was detected.

Recommendations of the Society of Thoracic Surgery and the Section of Cardiothoracic and Vascular Surgery of the Spanish Society of Anesthesia, Resuscitation and Pain Therapy, for patients undergoing lung surgery included in an intensified recovery program

In recent years, multidisciplinary programs have been implemented that include different actions during the pre, intra and postoperative period, aimed at reducing perioperative stress and therefore improving the results of patients undergoing surgical interventions. Initially, these programs were developed for colorectal surgery and from there they have been extended to other surgeries. Thoracic surgery, considered highly complex, like other surgeries with a high postoperative morbidity and mortality rate, may be one of the specialties that most benefit from the implementation of these programs. This review presents the recommendations made by different specialties involved in the perioperative care of patients who require resection of a lung tumor. Meta-analyzes, systematic reviews, randomized and non-randomized controlled studies, and retrospective studies conducted in patients undergoing this type of intervention have been taken into account in preparing the recommendations presented in this guide. The GRADE scale has been used to classify the recommendations, assessing on the one hand the level of evidence published on each specific aspect and, on the other hand, the strength of the recommendation with which the authors propose its application. The recommendations considered most important for this type of surgery are those that refer to pre-habilitation, minimization of surgical aggression, excellence in the management of perioperative pain and postoperative care aimed at providing rapid postoperative rehabilitation.

Enhanced Recovery Pathway in Lung Resection Surgery: Program Establishment and Results of a Cohort Study Encompassing 1243 Consecutive Patients

Simple Summary

Enhanced Recovery Pathways (ERP) have been scarcely assessed in lung cancer surgery. We performed a two-step audit for our experience: the first dealing with our initial experience focusing on patients undergoing segmentectomies and lobectomies, the second including all subsequent consecutive patients undergoing all kind of lung resections for NSCLC. The first step aimed at auditing results of ERP on occurrence of postoperative complications and at assessing which ERP components were associated with improved short-term outcomes. We also audited late results by assessing long-term survival of patients in the first step of our study. The second step aimed at auditing on large-scale short-term results of the ERP in a real-life setting. In total, 166 patients were included in the first period. No postoperative death occurred. The overall adverse events rate was 30%. In multivariate analyzes, the only element associated with reduced adverse postoperative events was chest tube withdrawal within POD2. The 1-, 3- and 5-year survival rates were 97%, 86.1%, and 76.3%, respectively. In the second period, 1077 patients were included; 11 patients died during the postoperative period. The overall postoperative adverse event rate was 30.3%. Thoracoscore independently predicted postoperative death, the occurrence of complications (all-kind, minor, major, or respiratory ones). We conclude that compliance to ERP procedures and early chest tube removal are associated with reduced postoperative events in patients with lung resection surgery. Thoracoscore is a useful tool in predicting mortality and postoperative adverse events.

Abstract

Introduction: In spite of increasing diffusion, Enhanced Recovery Pathways (ERP) have been scarcely assessed in large scale programs of lung cancer surgery. The aim of this study was auditing our practice. Methods: A two-step audit program was established: the first dealing with our initial ERP experience in patients undergoing non-extended anatomical segmentectomies and lobectomies, the second including all consecutive patients undergoing all kind of lung resections for NSCLC. The first step aimed at auditing results of ERP on occurrence of postoperative complications and at assessing which ERP components are associated with improved short-term outcomes. We also audited late results by assessing long-term survival of patients in the first step of our study. The second step aimed at auditing on large-scale short-term results of the ERP in a real-life setting. Results: Over a one-year period, 166 patients were included. The median number of ERP procedures per patient was three (IQR 3–4). No postoperative death occurred. The overall adverse events rate was 30%. In multivariate analyzes, the only element associated with reduced adverse postoperative events was chest tube withdrawal within POD2 (OR = 0.21, 95% CI (0.10–0.46)). The 1-, 3-, and 5-year survival rates were 97%, 86.1%, and 76.3%, respectively. In the second period, 1077 patients were included in our ERP; 11 patients died during the postoperative period or within 30 days of operation (1.02%). The overall postoperative adverse event rate was 30.3%, major complication occurring in 134 (12.4%), and minor ones in 192 (17.8%). Respiratory complications occurred in 64 (5.9%). Thoracoscore independently predicted postoperative death, the occurrence of complications (all-kind, minor, major, or respiratory ones). Conclusions: Compliance to ERP procedures and early chest tube removal are associated with reduced postoperative events in patients with lung resection surgery. In a large setting scale, ERP can be applied with satisfactory results in terms of mortality and morbidity. Thoracoscore is a useful tool in predicting mortality and postoperative adverse events.

[The role of the intensive care unit after thoracic surgery]

Lung (bronchial) cancer is the leading cause of cancer-related death in Western countries today. Thoracic surgery represents a major therapeutic strategy and the various advances made in recent years have made it possible to develop less and less invasive techniques. That said, the postoperative period may be lengthy, post-surgical approaches need to be more precisely codified, and it matters that the different interventions involved be supported by sound scientific evidence. To date, however, there exists no evidence that preventive postoperative admission to intensive care is beneficial for patients having undergone lung resection surgery without immediate complications. A stratification of the risk of complications taking into consideration the patient's general state of health (e.g., nutritional status, degree of autonomy, etc.), comorbidities and type of surgery could be a useful predictive tool regarding the need for postoperative intensive care. However, serious post-operative complications remain relatively frequent and post-operative management of these intensive care patients is liable to become complex and long-lasting. In the aftermath of the validation of "enhanced recovery after surgery" (ERAS) in thoracic surgery, new protocols are needed to optimize management of patients having undergone pulmonary resection. This article focuses on the main postoperative complications and more broadly on intensive care patient management following thoracic surgery.

Safety and feasibility study of uniportal video-assisted thoracoscopic pulmonary wedge resection without postoperative chest tube drainage: a retrospective propensity score-matched study

OBJECTIVES

The aim of this study was to assess the impact of postoperative chest tube drainage (CTD) on safety and postoperative recovery by comparing patients with pulmonary nodule undergoing uniportal video-assisted thoracoscopic pulmonary wedge resection with and without postoperative CTD.

METHODS

We retrospectively analysed the data of patients who underwent video-assisted thoracoscopic pulmonary wedge resection for pulmonary nodule at our hospital between 2018 and 2022. In cases where a 12-Fr chest tube was used following the procedure, the tube was not usually removed until the day after surgery. Therefore, the eligible patients were categorized into the drainage tube or the no-drainage tube group according to the use of postoperative CTD. Propensity score matching at a ratio of 1:1 was performed using clinicopathologic and demographic variables. The highest postoperative pain score, postoperative complication rate, postoperative length of stay and hospitalization costs were compared between the 2 groups.

RESULTS

A total of 275 eligible patients, including 150 and 125 patients in the drainage tube and no-drainage tube groups, respectively, were included in the study. After propensity score matching, there were 102 patients in each group. The postoperative complication rate during hospitalization and at 1 week and 1 month after discharge were not significantly different between the 2 groups (P > 0.05 for all). The highest postoperative pain score was significantly lower in the no-drainage tube group than in the drainage tube group [2.02 (standard deviation: 0.81) days vs 2.31 (standard deviation: 0.76) days, P = 0.008]. The postoperative length of stay was significantly shorter in the no-drainage tube group than in the drainage tube group {3.00 [interquartile ranges (IQRs): 2.00-4.00] days vs 2.00 (IQRs: 1.00-3.00) days, P < 0.001}. Similarly, the total hospitalization costs were significantly lower in the no-drainage tube group than in the drainage tube group [33283.74 (IQRs: 27098.61-46718.56) yuan vs 26598.67 (IQRs: 22965.14-29933.67) yuan, P < 0.001].

CONCLUSIONS

Omission of postoperative CTD was safe and feasible in patients with pulmonary nodule undergoing wedge resection. The no-postoperative-drainage policy can substantially shorten the length of hospital stay and reduce the postoperative pain and hospitalization costs without increasing the risk of postoperative complications.

Is there an ideal position and size of chest drain following anatomical lung resection?

BACKGROUND

Chest drains are placed after surgery to enable lung re-expansion. However, there remains little guidance on optimal placement. This study aims to identify the ideal size and position for chest drain insertion with regards to post-operative outcomes.

METHODS

383 patients undergoing lobectomy in 1-year had their chest drain size and x-ray position noted (1 (apical), 2 (mid-zone) or 3 (basal)). Primary outcome was residual air space on immediate post-operative x-ray. Secondary outcomes were length of drain in situ (<72 versus ≥72 h), persisting pleural effusion, surgical emphysema, post-operative pneumonia (POP), and length of hospital stay (<5 versus ≥5 days). Fisher's exact analysis for the primary outcome and binary logistic regression analysis for all outcomes were used. Results presented as odds ratios (OR±95%CI).

RESULTS

Univariate analysis for residual air space showed increased risk in area 2 (OR = 1.61, p = 0.041) and 3 (OR = 2.59, p = 0.0043) compared with area 1. Multivariate analysis for residual air space showed increased risk in area 2 (OR = 2.39, p < 0.001) and 3 (OR = 2.86, p < 0.001) compared with area 1. Drain size had no impact on residual air space in univariate or multivariate analysis. Multivariate analysis showed area 2 drains remained in situ for >72 h (OR = 1.49, p = 0.017), had persisting effusions (OR = 2.03, p = 0.004) and POP (OR = 2.10, p = 0.023) compared with area 1. This risk is magnified further for drains in area 3. Drains ≥28F had reduced risk of surgical emphysema (OR = 0.23, p = 0.027) in multivariate analysis.

CONCLUSION

A ≥28F, apical chest drain reduces the risk of post-operative complications, allowing early removal and discharge.

Single-port VATS combined with non-indwelling drain in ERAS: a retrospective study

Background

We investigated single-port video-assisted thoracoscopic surgery (VATS) combined with a postoperative non-indwelling drain in enhanced recovery after surgery (ERAS).

Methods

The clinical data of 127 patients who underwent double- and single-port VATS from January 2018 to December 2019 were analyzed retrospectively. The groups constituted 71 cases undergoing double-port and 56 cases undergoing single-port VATS (30 cases in the indwelling drain group and 26 cases in the non-indwelling drain group). The incidence of postoperative complications, pain scores, and postoperative hospital stay were compared between the two groups.

Results

Compared with the double-port group, the single-port group had shorter postoperative hospital stays and lower pain scores on the first and third postoperative days (P < 0.05). Pain scores on the first and third days were lower in the single-port non-indwelling drain group than in the single-port indwelling drain group (P < 0.05), and the postoperative hospitalization time was significantly shorter in the single-port group (P < 0.05). However, there was no significant difference between the two groups for operation time, incidence of complications, and pain scores 1 month after operation (P > 0.05).

Conclusions

The combination of single-port VATS with a non-indwelling drain can relieve postoperative pain, help patients recover quickly, and is in accordance with ERAS.

Pulmonary function after segmentectomy versus lobectomy in patients with early-stage non-small-cell lung cancer: a meta-analysis

Objective

Segmentectomy is widely performed for early-stage lung cancer. However, the effects of segmentectomy versus lobectomy on pulmonary function remain unclear. We performed a meta-analysis with the aim of comparing segmentectomy and lobectomy in terms of preservation of pulmonary function in patients with early-stage non-small-cell lung cancer (NSCLC).

Methods

We conducted a literature search of PubMed using the terms ‘pulmonary function’ AND ‘segmentectomy’ AND ‘lobectomy’. The primary outcomes of interest were the forced expiratory volume in 1 second (FEV1), FEV1 as percent of predicted (%FEV1), change in FEV1 (Δ%FEV1), and the ratio of postoperative to preoperative FEV1.

Results

Thirteen studies comprising 2027 patients met the inclusion and exclusion criteria and were included for analysis, including 787 patients in the segmentectomy group and 1240 patients in the lobectomy group. Patients in the segmentectomy group showed significantly better preservation of FEV1 and %FEV1 compared with the lobectomy group. The reduction in FEV1 after surgery was significantly less in the segmentectomy group compared with the lobectomy group, and Δ%FEV1 was significantly higher in the segmentectomy group than in the lobectomy group.

Conclusion

Segmentectomy results in better preservation of pulmonary function compared with lobectomy in patients with early-stage NSCLC.

Drainless Thoracoscopic Lobectomy for Lung Cancer

OBJECTIVES: Drainless video-assisted thoracoscopic (VATS) wedge resection has been demonstrated as feasible in treating various lung diseases. However, it remains unknown whether this surgical technique can be effectively applied to lobectomy. In the current study, we evaluated the perioperative outcome of drainless, minimally invasive lobectomy in patients with lung cancer. METHODS: A total of 26 lung cancer patients who received surgery-performed pulmonary lobectomy were enrolled. The perioperative outcomes were analyzed based on a propensity score matching a comparison with those who had chest drainage. RESULTS: No major surgical morbidity and mortality was noted during the perioperative period. The mean of postoperative hospital stay was 5.08 ± 2.48 days. There was no significant difference in postoperative hospital stay between the two groups of patients. However, the presence of significant postoperative pain (VAS score > 30) on the first day after surgery was less in the drainless group (34.6% vs. 3.8%; p = 0.005). CONCLUSIONS: Our results demonstrated that drainless, minimally invasive lobectomy for selected lung cancer patients is feasible. Further evaluation of its impact on short- and long-term surgical outcomes is required in the future.

AAAPT Diagnostic Criteria for Acute Thoracic Surgery Pain

Patients undergoing thoracic surgery experience particular challenges for acute pain management. Availability of standardized diagnostic criteria for identification of acute pain after thoracotomy and video assisted thoracic surgery (VATS) would provide a foundation for evidence-based management and facilitate future research. The Analgesic, Anesthetic, and Addiction Clinical Trial Translations, Innovations, Opportunities, and Networks (ACTTION) public-private partnership with the United States Food and Drug Administration, the American Pain Society (APS), and the American Academy of Pain Medicine (AAPM) formed the ACTTION-APS-AAPM Pain Taxonomy (AAAPT) initiative to address absence of acute pain diagnostic criteria. A multidisciplinary working group of pain experts was invited to develop diagnostic criteria for acute thoracotomy and VATS pain. The working group used available studies and expert opinion to characterize acute pain after thoracotomy and VATS using the 5-dimension taxonomical structure proposed by AAAPT (i.e., core diagnostic criteria, common features, modulating factors, impact/functional consequences, and putative mechanisms). The resulting diagnostic criteria will serve as the starting point for subsequent empirically validated criteria. PERSPECTIVE ITEM: This article characterizes acute pain after thoracotomy and VATS using the 5-dimension taxonomical structure proposed by AAAPT (ie, core diagnostic criteria, common features, modulating factors, impact and/or functional consequences, and putative mechanisms).

Recommendations of the Society of Thoracic Surgery and the Section of Cardiothoracic and Vascular Surgery of the Spanish Society of Anesthesia, Resuscitation and Pain Therapy, for patients undergoing lung surgery included in an intensified recovery program

In recent years, multidisciplinary programs have been implemented that include different actions during the pre, intra and postoperative period, aimed at reducing perioperative stress and therefore improving the results of patients undergoing surgical interventions. Initially, these programs were developed for colorectal surgery and from there they have been extended to other surgeries. Thoracic surgery, considered highly complex, like other surgeries with a high postoperative morbidity and mortality rate, may be one of the specialties that most benefit from the implementation of these programs. This review presents the recommendations made by different specialties involved in the perioperative care of patients who require resection of a lung tumor. Meta-analyses, systematic reviews, randomized and non-randomized controlled studies, and retrospective studies conducted in patients undergoing this type of intervention have been taken into account in preparing the recommendations presented in this guide. The GRADE scale has been used to classify the recommendations, assessing on the one hand the level of evidence published on each specific aspect and, on the other hand, the strength of the recommendation with which the authors propose its application. The recommendations considered most important for this type of surgery are those that refer to pre-habilitation, minimization of surgical aggression, excellence in the management of perioperative pain and postoperative care aimed at providing rapid postoperative rehabilitation.

[Thoracic Surgery Without Chest Tube: The Current Situation in Germany]

BACKGROUND

Over the last decades, several techniques have been implemented to reduce the invasiveness of thoracic surgery. Omitting chest tubes can lead to less postoperative pain and a shorter length of hospital stay. This study examines the extent to which German surgeons use the tubeless technique and what experience they have had with it.

MATERIALS AND METHODS

We conducted a nationwide survey, supported by the German Society of Thoracic Surgery (DGT). A digital questionnaire was sent to all leading thoracic surgeons with DGT membership between July and September 2020.

RESULTS

63 of 161 surgeons (39%) returned the questionnaires. The tubeless technique was used in 1.9% of thoracic surgery procedures performed last year. 59% of hospitals have implemented the technique; 24% of them also performed lung resections that way. The majority of respondents (79%) believe that the tubeless technique causes less postoperative pain; 16% see no advantage. Pleural effusion was ranked as the most important contraindication (76%). All participating surgeons agree that the absence of an air fistula is a prerequisite for performing lung resections using the tubeless technique - commonly checked by an underwater leak test (73%), and/or with a digital drainage system (53%), partially under pressure controlled ventilated lungs. Almost half of the respondents (46%) have not observed any complications using the tubeless technique.

CONCLUSION

Most German thoracic surgeons consider the tubeless technique safe and advantageous over the conventional technique. However, the case load is low and only 59% of the surgeons surveyed have experience with this technique. Randomised clinical trials concerning selection criteria and the procedural pathway may help increase the use.

"Tubeless" esophagectomy: Less is more

The esophageal cancer surgery is a complex procedure with elevated rates of both morbidity and mortality, which is why, in order to achieve adequate results, it should be performed in high volume centers, where complete multidisciplinary support is available and recent clinical guidelines are applied. We describe the initial experience and the technique of "tubeless" esophagectomy where esophageal resection and mediastinal lymphadenectomy are performed and no drains nor tubes of any kind are placed, with the aim to decrease the level of surgical aggression, enhance the postoperative comfort and accelerate the patient́s recovery.

Low suction on digital drainage devices promptly improves post-operative air leaks following lung resection operations: a retrospective study

BACKGROUND

We investigated the most effective suction pressure for preventing or promptly improving postoperative air leaks on digital drainage devices after lung resection.

METHODS

We retrospectively analyzed the postoperative data of 242 patients who were monitored with a digital drainage system after pulmonary resection in our institution between December 2017 and June 2020. We divided the patients into three groups according to the suction pressure used: A (low-pressure suction group: - 5 cm H₂O), B (intermediate-pressure group: - 10 cm H₂O), and C (high-pressure suction group: - 20 cm H₂O). We evaluated the duration of air leaks, timing of chest tube replacement, the amount of postoperative air leak, volume of fluid drained before chest tube removal, and the total number of air leaks during drainage.

RESULTS

In total, 217 patients were included in this study. The duration of air leaks gradually decreased with significant difference between the groups, the highest decrease in A, the lowest decrease in C (P = 0.019). Timing of chest tube replacement, on the other hand, did not significantly differ between the three groups (P = 0.126). The number of postoperative air leaks just after surgery did not significantly differ between the three groups (P = 0.175), but the number of air leaks on postoperative day 1 were fewest in group A, then B, and greatest in group C (P = 0.033). The maximum amount of air leaks during drainage was lowest in A, then B, and highest in C (P = 0.036). Volume of fluid drained before chest tube removal did not significantly differ between the three groups (P = 0.986).

CONCLUSION

Low-pressure suction after pulmonary resection seems to avoid or promptly improve postoperative air leaks in digital drainage devices after lung resection.

TRIAL REGISTRATION

This is a single-institution, retrospective analysis-based study of data from an electronic database. Study protocol was approved by the Akashi Medical Center Institutional Research Ethics Board (approval number: 2020-9).

[Study on the Application of A New Type of Anhydrous Thoracic Negative Pressure Drainage Device in Patients after Thoracic Surgery]

BACKGROUND

After general thoracic surgery, a chest tube is usually placed for closed drainage to expel gas accumulation in the thoracic cavity and fluid accumulation to promote lung re-expansion. It can also be observed whether there is active bleeding after the operation and whether there is a pulmonary leak. The conventional drainage of the chest cavity is connected with a water-sealed drainage bottle, and the patient condition is judged by observing the drainage situation and the fluctuation of the water column, which is a very classic method. However, the water-sealed bottle has the disadvantages of being easy to overturn and inconvenient to carry, which is not conducive to the early activities of patients. Under the concept of accelerated rehabilitation, our center applied a new type of anhydrous thorax negative pressure drainage device and achieved good results. The purpose of this study was to observe the effect of a new type of anhydrous thoracic negative pressure drainage device in patients after thoracic surgery.

METHODS

Retrospective analysis of patients who underwent lung surgery in the First Affiliated Hospital of Zhejiang University Medical College from January 2018 to December 2019, patients were divided into two groups. One group of patients used a traditional closed-chest drainage water-sealed bottle as a control group, and the other group used a new type of anhydrous negative-pressure drainage bottle as an experimental group. Patients' gender, age, hypertension, diabetes, smoking history, surgical incisions and surgical methods, and the length of hospital stay and postoperative hospital stay were calculated.

RESULTS

There were no statistical differences in age, gender, comorbidities (hypertension, diabetes, smoking history), scope of surgery, and duration of surgery between the two groups of patients, but there were statistical differences in surgical incisions between the two groups of patients (P=0.01). We found that patients using the new waterless negative pressure drainage device were shorter than patients with water negative pressure drainage device in terms of postoperative hospital stay and total hospitalization time, and the difference was statistically significant (P=0.02, P=0.04).

CONCLUSIONS

The new type of anhydrous thoracic negative pressure drainage device has a good effect on the rapid recovery and advancement after thoracic surgery.

The Early Perioperative Outcomes of Subxiphoid Approach Versus Lateral Intercostal Approach Thoracoscopic Thymectomy for Thymic Tumors: A Meta-Analysis

Objectives: To systematically evaluate the early perioperative outcomes regarding the safety and efficacy of subxiphoid thoracoscopic thymectomy (STT) versus lateral intercostal thoracoscopic thymectomy (LITT) for patients with thymic tumors. Methods: A thorough literature search of the following online databases was performed: Web of Science, PubMed, Embase, Cochrane Library, Google Scholar, and ClinicalTrials.gov. Original research articles published before December 30, 2020, that compared STT with LITT were included. Meta-analysis was performed for early perioperative outcomes, including blood loss, pain score, duration of hospital stay, operative time, chest tube drainage time, and incidence of postoperative complications. Results: Six studies that included 604 patients were finally selected for our analysis, with 296 cases of STT and 308 cases of LITT. Our results showed that compared with LITT, STT was associated with less blood loss (standardized mean difference = -0.81, 95% confidence interval [CI] = -1.49 to -0.14, P = .02), a lower pain score (weighted mean difference [WMD] = -2.55, 95% CI = -3.52 to -1.59; P < .00001), and a shorter hospital stay (WMD = -1.37, 95% CI = -2.37 to -0.36; P = .008), whereas there were no significant differences with regard to the operative time (WMD = -10.04, 95% CI = -22.29 to 2.21, P = .11), chest tube drainage time (WMD = -0.58, 95% CI = -1.17 to 0.02, P = .06), and the incidence of postoperative complications (odds ratio = 0.75, 95% CI = 0.39 to 1.44, P = .38). Conclusions: The current analysis suggests that STT is superior to LITT with respect to the early perioperative outcomes, and STT is a safe and effective surgical method for patients with thymic tumors.

Efficacy and safety of omitting chest drains after video-assisted thoracoscopic surgery: a systematic review and meta-analysis

BACKGROUND

The aim of this systematic review and meta-analysis was to determine the efficacy and safety of omitting chest drains compared to routine chest drain placement after video-assisted thoracoscopic surgery (VATS).

METHODS

Five bibliographic databases, ClinicalTrials.gov and PROSPERO were comprehensively searched from inception to July 29, 2020 (no language restrictions). Postoperative outcomes were extracted and synthesized complying with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Risk of bias (RoB) including non-reporting bias, heterogeneity, and sensitivity were assessed. Subgroup analyses were performed based on study design.

RESULTS

Of 7,166 identified studies, 10 studies [four randomized controlled trials (RCTs) and six non-RCTs] with 1,079 patients were included. There were 561 patients in the no chest drain group (NCD) and 518 patients in the standard chest drain group (CD). In pairwise analysis the NCD group had significant shorter length of stay (LOS) [weighted mean difference (WMD) -1.53 days, P<0.001], less postoperative pain scores (WMD -1.09, P=0.002), but higher risk of drain insertion or thoracocentesis [risk radio (RR) 3.02, P=0.040]. There were no significant differences on the incidence of minor pneumothorax (RR 1.77, P=0.128), minor pleural effusion (RR 1.88, P=0.219), minor subcutaneous emphysema (RR 1.37, P=0.427) or pneumonia (RR 0.53, P=0.549). No mortality was observed in either group during the observation period (in-hospital or 30-day mortality).

CONCLUSIONS

Omitting chest drains in selected patients after VATS seems effective leading to enhanced recovery with shorter length of postoperative stay and less pain but with a higher risk of drain insertion or thoracocentesis. However, a major part of the evidence comes from observational studies with high RoB. Further RCTs are needed to improve the current evidence.

Guidelines on enhanced recovery after pulmonary lobectomy

OBJECTIVE

To establish recommendations for optimisation of the management of patients undergoing pulmonary lobectomy, particularly Enhanced Recovery After Surgery (ERAS).

DESIGN

A consensus committee of 13 experts from the French Society of Anaesthesia and Intensive Care Medicine (Soci,t, franOaise d'anesth,sie et de r,animation, SFAR) and the French Society of Thoracic and Cardiovascular Surgery (Soci,t, franOaise de chirurgie thoracique et cardiovasculaire, SFCTCV) was convened. A formal conflict-of-interest policy was developed at the onset of the process and enforced throughout. The entire guidelines process was conducted independently of any industry funding. The authors were advised to follow the principles of the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system to guide assessment of quality of evidence.

METHODS

Five domains were defined: 1) patient pathway and patient information; 2) preoperative management and rehabilitation; 3) anaesthesia and analgesia for lobectomy; 4) surgical strategy for lobectomy; and 5) enhanced recovery after surgery. For each domain, the objective of the recommendations was to address a number of questions formulated according to the PICO model (Population, Intervention, Comparison, Outcome). An extensive literature search on these questions was carried out and analysed using the GRADE® methodology. Recommendations were formulated according to the GRADE® methodology, and were then voted by all experts according to the GRADE grid method.

RESULTS

The SFAR/SFCTCV guideline panel provided 32 recommendations on the management of patients undergoing pulmonary lobectomy. After two voting rounds and several amendments, a strong consensus was reached for 31 of the 32 recommendations and a moderate consensus was reached for the last recommendation. Seven of these recommendations present a high level of evidence (GRADE 1+), 23 have a moderate level of evidence (18 GRADE 2+ and 5 GRADE 2-), and 2 correspond to expert opinions. Finally, no recommendation was provided for 2 of the questions.

CONCLUSIONS

A strong consensus was expressed by the experts to provide recommendations to optimise the whole perioperative management of patients undergoing pulmonary lobectomy.
