A six-week inspiratory muscle training and aerobic exercise improves respiratory muscle strength and exercise capacity in lung cancer patients after video-assisted thoracoscopic surgery: A randomized controlled trial.

OBJECTIVE: To compare the postoperative outcomes of inspiratory muscle training and aerobic exercise, along with standard care, on lung cancer patients undergoing video-assisted thoracoscopic surgery (VATS). DESIGN: A parallel-group, single-blind randomized clinical trial. SETTING: Thoracic surgery ward and outpatient clinic in a teaching hospital. SUBJECTS: Overall 63 patients underwent VATS were randomly assigned to a triaging (TG, n = 32) or control group (CG, n = 31). A total of 54 patients (TG, n = 26; CG, n = 28) completed the study. INTERVENTION: TG: six-week threshold inspiratory muscle training and aerobic exercise. CG: standard care. MAIN MEASURES: Maximum inspiratory pressure (PImax), maximum expiratory pressure (PEmax) lung expansion volume, and 6-min walking test (6MWT) were performed on the day of chest tube removal (baseline), and 2, 6, and 12 weeks postoperatively. RESULTS: The TG showed significant improvement in PImax at week 6 (71.6 ± 34.9 vs. 94.3 ± 32.8 cmH2O, P = 0.018), PEmax at week 2 (70.9 ± 24.3 vs. 90.9 ± 28.2 cmH2O, P = 0.015) and week 12 (76.1 ± 20.2 vs. 98.6 ± 35.3 cmH2O, P = 0.012), the lung expansion volume at week 2 (1080 ± 433 vs 1457 ± 624 mL, P = 0.02) and week 12 (1200 ± 387 vs 1885 ± 678 mL, P < 0.001), in addition to the 6MWT at week 2 (332 ± 78 vs 412 ± 74 m, P = 0.002), week 6 (360 ± 70 vs 419 ± 60 m, P = 0.007) and week 12 (360 ± 58 vs 402 ± 65 m, P = 0.036). CONCLUSION: A six weeks of inspiratory muscle training and aerobic exercise had improved respiratory muscle strength and aerobic exercise postoperatively in lung cancer patients after VATS as early as 2 weeks.

Four Hours Postoperative Mobilization is Feasible After Thoracoscopic Anatomical Pulmonary Resection.

BACKGROUND: We aimed to analyze the feasibility and risk factors associated with early mobilization (EM) within 4 h after thoracoscopic lobectomy and segmentectomy. METHODS: This study retrospectively evaluated 214 consecutive patients who underwent thoracoscopic anatomical pulmonary resection using our EM protocol between October 2017 and February 2019. We compared the correlations of the patients' characteristics including the total number of drugs and perioperative parameters such as air leak, and orthostatic hypotension (OH) between the EM (E group) and failed EM (F group) groups. Second, we evaluated risk factors for OH, which often causes critical complications. RESULTS: A total of 198 patients (92.5%: E group) completed the EM protocol, whereas 16 patients did not (7.5%: F group). The primary causes of failure were severe pain, air leak, postoperative nausea and vomiting, and OH (n = 1, 3, 8, and 4). Upon univariate analysis, air leakage, OH, and non-hypertension were identified as risk factors for failed EM (all p <0.05). EM was associated with a shortened chest tube drainage period (p <0.01). Thirty patients (14%) experienced OH, and 20% of them failed EM. A total number of drugs ≥5 (p = 0.015) was an independent risk factor for OH. Operative and anesthetic variables were not associated with EM or OH. CONCLUSIONS: The EM protocol was safe and useful for tubeless management. Surgeons should be advised to actively prevent air leak. Our EM protocol achieved a low frequency of OH in mobilization. Due to its versatility, our mobilization protocol may be promising, especially in patients without severe comorbidities. Clinical registration number: The study protocol was approved by the Review Board of Aichi Cancer Center (approval number: 2020-1-067).

Two-Week Multimodal Prehabilitation Program Improves Perioperative Functional Capability in Patients Undergoing Thoracoscopic Lobectomy for Lung Cancer: A Randomized Controlled Trial.

BACKGROUND: Patients with lung cancer often experience reduced functional capacity and quality of life after surgery. The current study investigated the impact of a short-term, home-based, multimodal prehabilitation program on perioperative functional capacity in patients undergoing video-assisted thoracoscopic surgery (VATS) lobectomy for nonsmall cell lung cancer (NSCLC). METHODS: A randomized controlled trial was conducted with 73 patients. Patients in the prehabilitation group (n = 37) received a 2-week multimodal intervention program before surgery, including aerobic and resistance exercises, respiratory training, nutrition counseling with whey protein supplementation, and psychological guidance. Patients in the control group (n = 36) received the usual clinical care. The assessors were blinded to the patient allocation. The primary outcome was perioperative functional capacity measured as the 6-minute walk distance (6MWD), which was assessed at 1 day before and 30 days after surgery. A linear mixed-effects model was built to analyze the perioperative 6MWD. Other outcomes included lung function, disability and psychometric evaluations, length of stay (LOS), short-term recovery quality, postoperative complications, and mortality. RESULTS: The median duration of prehabilitation was 15 days. The average 6MWD was 60.9 m higher perioperatively in the prehabilitation group compared to the control group (95% confidence interval [CI], 32.4-89.5; P < .001). There were no differences in lung function, disability and psychological assessment, LOS, short-term recovery quality, postoperative complications, and mortality, except for forced vital capacity (FVC; 0.35 L higher in the prehabilitation group, 95% CI, 0.05-0.66; P = .021). CONCLUSIONS: A 2-week, home-based, multimodal prehabilitation program could produce clinically relevant improvements in perioperative functional capacity in patients undergoing VATS lobectomy for lung cancer.

[Fast-track rehabilitation after anatomical lung resection: prospective single-center non-randomized trial]. / Prospektivnoe odnotsentrovoe nerandomizirovannoe issledovanie uskorennoi reabilitatsii patsientov posle anatomicheskikh rezektsii legkikh.

AIM: To present the results of fast track rehabilitation after anatomical lung resection. MATERIAL AND METHODS: Single-center prospective non-randomized trial has included patients for the period December 2014 - December 2016. Conventional protocol was applied in 124 patients, 58 patients after atypical lung resections or pneumonectomy were excluded from the study. Thus, there were 66 patients aged 61 (51; 67) years. Men/women ratio was 37:29. Lobectomy (n=55) and segmentectomy (n=11) were performed for lung cancer, metastatic injury and various inflammatory diseases in 53 (80.3%), 8 (12.1%) and 5 (7.6 %) cases, respectively. ASA risk score was II (16), III (46), IV (4). Video-assisted/open procedures ratio was 42 (63.6%) / 24 (36.4%). RESULTS: 30-day postoperative morbidity was 7.6% (5 out of 66 patients, 95% CI 3.3- 16.5). Pleural drainage tube was removed within the 1st postoperative day in 49 (74.2%) out of 66 patients. Prolonged insufficient aerostasis was observed in 3 patients followed by effective conservative treatment. Overall mortality was 3% (n=2, 95% CI 0.8- 10.4) due to pulmonary embolism and sudden cardiac death. Median of postoperative hospital-stay was 7 (6; 9) days without significant differences between groups of lobectomy and segmentectomy (p>0.05). CONCLUSION: Fast track rehabilitation protocol in thoracic surgery is safe and effective. Further studies are needed to justify early rehabilitation in high risk patients.

Thoracic enhanced recovery with ambulation after surgery: a 6-year experience.

OBJECTIVES: Our institution implemented a protocol known as thoracic enhanced recovery with ambulation after surgery (T-ERAS) in thoracic operations. The objective was early ambulation starting in the postoperative ambulatory care unit. METHODS: Video-assisted thoracoscopic surgery lobectomy patients are placed on a chair in the preoperative area and then walked to the operating room. Postoperatively, patients are placed on a chair as soon as possible. Our target ambulation goal was 250 feet within 1 h of extubation. Patients then walk to their hospital room. T-ERAS adoption and outcomes were compared to a pre-T-ERAS period, in addition to the comparing early and late T-ERAS cohorts. RESULTS: Over 6 years, 304 patients on T-ERAS underwent a planned video-assisted thoracoscopic surgery lobectomy. Median age was 67 years (range 41-87 years). The target goal was achieved in 187 of 304 (61.5%) patients and 277 of 304 (91.1%) patients ambulated 250 feet at any time in the postoperative ambulatory care unit. The T-ERAS period had a median length of stay of 1 day vs 2 days in the pre-T-ERAS period (P < 0.001). There were low rates of pneumonia (2/304, 0.7%), atrial fibrillation (12/304, 4.0%) and no postoperative mortalities for T-ERAS. The target goal was achieved at a greater rate in the late (92/132, 72.0%) versus early (28/75, 37%) T-ERAS cohort. The mean time to ambulation was reduced in the late cohort (46-81 min). CONCLUSIONS: Early postoperative ambulation was feasible and considered key in achieving low morbidity after video-assisted thoracoscopic surgery lobectomy. Adoption of T-ERAS improved over time. Further studies will help define adoptability at other sites and validate impact on improving outcomes.

Preoperative exercise training prevents functional decline after lung resection surgery: a randomized, single-blind controlled trial.

OBJECTIVES: To investigate the effects of a preoperative pulmonary rehabilitation programme in patients with lung cancer undergoing video-assisted thoracic surgery. DESIGN: Randomized, single-blind controlled trial. SETTING: Teaching hospital. SUBJECTS: Patients with suspected or confirmed lung cancer undergoing video-assisted thoracic surgery. INTERVENTION: Participants were randomized to either a prehabilitation group or a control group. Participants in the prehabilitation group underwent a combination of moderate endurance and resistance training plus breathing exercises three to five times per week. MAIN MEASURES: The primary outcome of the study was exercise capacity. Secondary outcomes were muscle strength (Senior Fitness Test), health-related quality of life (Short-Form 36) and the postoperative outcomes. Patients were evaluated at baseline (before randomization), presurgery (only the prehabilitation group), after surgery and three months post-operatively. RESULTS: A total of 40 patients were randomized and 22 finished the study (10 in the prehabilitation group and 12 in the control group). Three patients were lost to follow-up at three months. After the training, there was a statistically significant improvement in exercise tolerance (+397 seconds, p = 0.0001), the physical summary component of the SF-36 (+4.4 points, p = 0.008) and muscle strength ( p < 0.01). There were no significant differences between groups after surgery. However, three months postoperatively, significant differences were found in the mean change of exercise capacity ( p = 0.005), physical summary component ( p = 0.001) and upper and lower body strength ( p = 0.045 and p = 0.002). CONCLUSIONS: A pulmonary rehabilitation programme before video-assisted thoracic surgery seems to improve patients' preoperative condition and may prevent functional decline after surgery. Clinical Registration Number: NCT01963923 (Registration date 10/10/2013).

[Evolution of pain during respiratory rehabilitation after major lung resection]. / Évolution de la douleur en soins de suites et rééducation après résection pulmonaire majeure.

INTRODUCTION: Lung resection for cancer is the cause of significant postoperative pain. The aim of this study was to determine whether pulmonary rehabilitation could induce a resurgence of pain. METHODS: In 2014 and 2015, pulmonary rehabilitation was offered to all patients referred to our institution after lung resection for cancer. Patients were assessed at entry and departure for nociceptive pain, neuropathic pain (DN4), for quality of life using questionnaire EORTC QlQ-C30 and for anxiety and depression (HAD questionnaire). Pain was studied before and after the sessions of cycloergometer, gym and massages. RESULTS: During the period, 99 patients were admitted to our institution following lung resection for cancer. Medians changed during pulmonary rehabilitation from 3 to 1 for nociceptive pain (p<0.001), 3 to 3 for DN4 (NS), 50 to 67 for the quality of life score (p<0.001), 7 to 5 for the anxiety (p<0.001) and 5 to 3 for depression (p<0.0001). Pain remained stable during the sessions of cycloergometer and gym, and decreased during massage. Patients undergoing thoracotomy or video-assisted thoracic surgery evolved identically. CONCLUSION: Postoperative pulmonary rehabilitation after lung resection for cancer was not harmful. It was associated with a decrease in nociceptive pain and was without effect on neuropathic pain.

Nuss procedure for pectus excavatum in adults: long-term results in a prospective observational study.

OBJECTIVES: Since the end of the 1990s, the management of pectus excavatum has undergone major changes. The Nuss procedure (pectus bar) has been the method of choice for patients with pectus excavatum at Bern University Hospital for over a decade. The current study will describe our experiences, with a particular focus on long-term results in adults. METHODS: The prospective observational study began in autumn 2002. The Haller index was used to quantify pectus excavatum severity. Pulmonary function tests and cardiac examinations were performed preoperatively, and a standardized management for surgical techniques and for the pre- and postoperative treatments including long-term follow-up at 3, 12 and 36 months after surgery was developed. Quality of life and satisfaction with the cosmetic result after the Nuss procedure were evaluated. RESULTS: Better or much better quality of life after the Nuss procedure was observed: n = 108 (88.4%) at 3 months, n = 97 (89.0%) at 12 months and n = 87 (92.5%) at 36 months. Pain intensity decreased in the follow-up [pain score visual analogue scale (VAS) at 3 months: median 1 (0-7), 12 months: median 1 (0-4), 36 months: median 0.8 (0-5)]. After long-term observation, over 90% of patients described their quality of life after the operation as being better or much better. Satisfaction with the cosmetic results of the operation was also very high, with >90% of patients being satisfied. Only a very small group of patients suffered from pain in the long-term follow-up. Complications were rare (14.7%) and could be treated in most cases without reoperation. CONCLUSION: Our results demonstrate that the Nuss procedure is safe and can be performed with excellent results in adults, both in the short term and in the long term. The improved quality of life and patients' satisfaction with cosmetic results remained high in the long-term follow-up, 10 years after the surgical procedure.

[Outpatient thoracoscopic resection of lung nodules within a fast-track recovery program]. / Résection thoracoscopique ambulatoire de nodules pulmonaires dans le cadre de la réhabilitation précoce.

INTRODUCTION: The objectives of outpatient surgery are to reduce the risks related to the hospitalization, to improve the postoperative recovery and to optimize contact with family physicians. The objective of this work is to present the first unit of outpatient pulmonary surgery and to report the results of the resections of pulmonary nodules in outpatient surgery in the setting of early discharge. METHODS: The indications for the resection of nodules were discussed in a multidisciplinary thoracic oncology meeting. The patients underwent resection of one or more lung nodules by thoracoscopy after verification that they met the anaesthetic and surgical criteria for ambulatory surgery. We analyzed the characteristics of the population, the duration of surgery, the type of resection, the time of the chest drain removal and the postoperative follow-up. RESULTS: Between November 2013 and December 2014, 51 patients underwent sub-lobar pulmonary resections. Among them 7 patients (4 men and 3 women), with an average age of 57.6 years (39-64) and histories of malignant tumor, underwent 7 atypical resections and two segmentectomies in outpatient surgery (3 patients had two resections). The average operating time was 53.75min (30-90). The chest drain was removed before the third hour in 8 cases and on the third day in one case. The average tumor diameter was 10.375mm (6-23). The histology revealed a metastasis of colorectal carcinoma in 4 cases, a metastasis of a renal carcinoma in 1 case, an in situ adenocarcinoma in 1 case and a benign tumor in 3 cases. Neither recurrence nor complication was observed during an average follow-up of 6 months. CONCLUSION: Thanks to a protocol of early mobilisation and discharge included in a well established clinical care pathway, thoracoscopic resection of lung nodules is feasible, with safety in properly selected and prepared patients in outpatient surgery.

Fast-track video-assisted thoracoscopic surgery: future challenges.

OBJECTIVES: To provide a short overview of fast-track video-assisted thoracoscopic surgery (VATS) and to identify areas requiring further research. DESIGN: A literature search was made using key words including: fast-track, enhanced recovery, video-assisted thoracoscopic surgery, robot-assisted thoracoscopic surgery (RATS), robotic, thoracotomy, single-incision, uniportal, natural orifice transluminal endoscopic surgery (NOTES), chest tube, air-leak, digital drainage, pain management, analgesia, perioperative management, anaesthesia and non-intubated. References from articles were screened for further articles. Using abstracts, areas of interest for developing a fast-track protocol were selected. RESULTS: The minimally invasive approach can be divided into several surgical methods that need further research to establish superiority. The role of intubation has to be further examined as well as the role of chest drains. Multimodal analgesic treatment including preoperative methylprednisolone seems promising and requires further research. CONCLUSIONS: The fast-track data from other procedures may support future development and improvement of fast-track VATS.

Fast-track rehabilitation for lung cancer lobectomy: a five-year experience.

OBJECTIVE: Fast-track rehabilitation is a group of simple measures that reduces morbidity, postoperative complication and accelerates postoperative rehabilitation reducing hospital stay. It can be applied to lung cancer lobectomy. Fast-track rehabilitation cornerstones are: minimally invasive surgical techniques using video-assisted and muscle sparring incisions, normovolemia, normothermia, good oxygenation, euglicemia, no unnecessary antibiotics, epidural patient-controlled analgesia, systemic opiods-free analgesia, early ambulation and oral feeding. Our objective is to describe a five-year experience with fast-track rehabilitation for lung cancer lobectomy. PATIENTS AND METHODS: A retrospective non-controlled study including 109 consecutive patients submitted to fast-track rehabilitation in the postoperative care of lung cancer lobectomy was performed. Only collaborative patients who could receive double-lumen intubation, epidural catheters with patient-controlled analgesia, who had Karnofsky index of 100, previous normal feeding and ambulation, absence of morbid obesity, diabetes or asthma, were eligible. Postoperative oral feeding and aggressive ambulation started as soon as possible. RESULTS: Immediate postoperative extubation even in the operation room was possible in 107 patients and oral feeding and ambulation were possible before the first hour in 101 patients. Six patients could not receive early oral feeding or ambulate due to hypnosis secondary to preoperative long effect benzodiazepines. Two patients could not ambulate immediately due to epidural catheter misplacement with important postoperative pain. Ninety-nine discharges occurred at the second postoperative day, four of them with a chest tube connected to a Heimlich valve due to air leak. No complication of early feeding and ambulation was observed. Postoperative hypnosis due to long duration benzodiazepines or pain does not allow early oral feeding or ambulation. Avoiding long duration preoperative benzodiazepines, immediate postoperative extubation, regional thoracic PCA and early oral feeding and ambulation were related to a lesser frequency of complication and a shorter hospital stay. CONCLUSION: Fast-track rehabilitation for lung cancer lobectomies can be safely performed in a selected group of patients if a motivated multidisciplinary group of professionals is available and seems to reduce postoperative complication and hospital stay.

Side effects, complications and outcome of thoracoscopic sympathectomy for palmar and axillary hyperhidrosis in 406 patients.

BACKGROUND: Thoracic sympathectomy (TS) is the treatment of choice for severe primary hyperhidrosis. However, complications, side effects and satisfaction have not been well defined. OBJECTIVE: To analyze the complications, side effects, satisfaction degree and quality of life of patients after TS for primary upper limb hyperhidrosis. METHODS: One-year follow-up after 406 consecutive TS for primary upper limb hyperhidrosis. RESULTS: Bilateral TS was completed in all patients. Complications arose in 23 cases (5.6%), with pneumothorax being the most frequent. The success rate after discharge, 6 and 12 months was respectively, 100%, 98.1% and 96.5% for palmo-axillary hyperhidrosis; 100%, 99.3% and 97.8% for isolated palmar hyperhidrosis and 100%, 85.7% and 71.4% for isolated axillary hyperhidrosis. No persistence of hyperhidrosis was observed. Global recurrence was 3.7% (28.5% axillary hyperhidrosis group). Compensatory sweating (CS) appeared in 55% and was not related to the extension of the TS. Being female was a predisposing factor of CS (p<0.004). Excessive dryness appeared at 9% and was associated with extensive TS (P<0.001). Plantar hyperhidrosis improved at 33.6%, worsened at 10% and remained stable during the follow-up. Satisfaction degree decreased with the passage of time and was associated with recurrence. Quality of life was excellent at discharge, 6 and 12 month in 100%, 100% and 97%, respectively. CONCLUSIONS: Pneumothorax is the most frequent complication of TS. CS is the main and undesirable side effect, appears with the passage of time, and is not related to the extension of TS. Being female is the only predictor factor of suffering CS. Plantar hyperhidrosis improves initially, although tends to reappear. Excessive dryness appears in extensive TS and does not improve over time. Postoperative satisfaction degree is high but decreases over time owing to the appearance of recurrence. Effectiveness and the absence of CS determine an excellent quality of life. Six percent of the patients regret the surgery because of severe CS. Informing patients of possible side effects before TS is essential.

Postoperative pain detracts from early health status improvement seen after video-assisted thoracoscopic lung volume reduction surgery.

OBJECTIVES: To assess the impact of lung volume reduction surgery (LVRS) on postoperative pain. METHODS: Fifty-two patients, 34 male/18 female, median age 59 (46-70) years, underwent unilateral video-assisted thoracoscopic (VAT) LVRS. FEV(1), TLC, RV and RV/TLC ratio were assessed preoperatively and at 3, 6, 12 and 24 months post surgery. At the same time interval health status was assessed by Euroquol and SF 36 questionnaires. RESULTS: Significant improvements in health status, as assessed by SF 36, persisted from 3 months to 1 year. However, in the pain domain there was a worsening of the mean score from 74 preoperatively to 64 at 3 months, 68 at 6 months, 73 at 12 months and 65 at 24 months. The improvements in Euroquol score were not statistically significant. However, they became significant for at least 2 years postoperatively, when those patients who had a worsening pain score postoperatively were excluded. While the percentage of patients with a worsening of pain scores measured with SF 36 remained between 40 and 45% even 2 years after LVRS, when using Euroquol this percentage did decrease from 30% at 3 months to 14% at 2 years. There was no significant correlation between the change of scores and length of operation, hospital stay or air leak. It was also not statistically significant whether these patients had an extra procedure (redo thoracotomy or insertion of extra drain postoperatively). There were some significant correlations between changes in hyperinflation and changes in pain scores but this was not consistent for Euroquol and SF 36. CONCLUSION: Postoperative pain detracts from global improvement in health status after LVRS even after unilateral VATS. There may be an influence of alterations in chest mechanics after surgery on the development of pain.

The impact of thoracic surgical access on early shoulder function: video-assisted thoracic surgery versus posterolateral thoracotomy.

OBJECTIVE: Whether video-assisted thoracic surgery (VATS) is associated with less shoulder dysfunction when compared with posterolateral thoracotomy (PLT) remains unclear. We therefore conducted this prospective study to assess the shoulder function in patients following major lung resection using either the VATS or PLT approach. METHODS: Twenty-nine consecutive patients were prospectively recruited into the study. Eighteen patients underwent major lung resection through VATS (VATS group) and 11 patients through PLT (open group). Shoulder function was measured preoperatively, and postoperatively at 1 week, 1 month and at 3 months. All assessments were done by two experienced physiotherapists using the American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form. RESULTS: Shoulder strength was significantly better preserved in the VATS group at 1 week after surgery when compared with the PLT group (92 versus 81% of preoperative value; P=0.024). VATS patients also had better range of motion especially with respect to external rotation at 1 week (98 versus 91%; P=0.015) and forward elevation at 1 month (98 versus 93%; P=0.024) and 3 months after surgery (100 versus 96%; P=0.021). Analgesic requirement was significantly less in the VATS group postoperatively at 1 week (P=0.009) and 1 month (P=0.004). CONCLUSIONS: VATS major lung resection is associated with significantly less shoulder dysfunction and pain medication requirement in the early postoperative period when compared to the PLT approach.
