Tips and tricks in video-assisted thoracoscopic surgery lobectomy.

In 2012, open procedures represented 63% of the total number of lobectomies performed in our unit; in 2015, video-assisted thoracoscopic surgery (VATS) lobectomy numbers increased up to 66% of the total number of lobectomies performed. When carrying out the procedures, we followed the guidelines presented by the International VATS Lobectomy Consensus Group regarding indications, contraindications, preoperative investigations and conversions. In view of 280 VATS major lung resections from May 2012 to May 2016, we describe some tips and tricks that can be useful in this surgical technique, from general principles to single operative procedures.

Comparison Between Electronic and Traditional Chest Drainage Systems: A Multicenter Randomized Study.

BACKGROUND: Air leak is the major factor that influences the permanence of the chest tube and the in-hospital length of stay (LOS) among patients undergoing lung resections. The aim of this study was to determine whether the use of digital chest drain systems, compared with traditional ones, reduced the duration of chest drainage and postoperative in-hospital LOS in patients undergoing video-assisted thoracoscopic (VATS) lobectomy. METHODS: The study was a prospective, randomized, multicenter trial. Patients undergoing VATS lobectomy were randomized in 2 groups, receiving a digital drain system or a traditional one and managed accordingly to the protocol. RESULTS: Among 503 patients who fulfilled inclusion criteria and were randomized, 38 dropped out after randomization. Finally, 465 patients were analyzed, of whom 204 used the digital device and 261 the traditional one. In the digital group, there was a significantly shorter median chest tube duration of 3 postoperative days (interquartile range [IQR], 2-4 days) vs 4 postoperative days (IQR, 3-4 days; P = .001) and postoperative in-hospital LOS of 4 days (IQR, 3-6 days) vs 5 days (IQR, 4-6 days; P = .035). Analysis of predictors for increased duration of air leaks showed a relationship with male sex (P = .039), forced expiratory volume in 1 second percentage (P = .004), forced vital capacity percentage (P = .03), and presence of air leaks at the end of surgery (P = .001). CONCLUSIONS: In patients undergoing VATS lobectomy, the use of a digital drainage system allows an earlier removal of the chest drain compared with the traditional system, leading to a shorter in-hospital LOS.

The Overweight Paradox: Impact of Body Mass Index on Patients Undergoing VATS Lobectomy or Segmentectomy.

The aim of this study was to assess the impact of BMI on perioperative outcomes in patients undergoing VATS lobectomy or segmentectomy. Data from 5088 patients undergoing VATS lobectomy or segmentectomy, included in the VATS Group Italian Registry, were collected. BMI (kg/m2) was categorized according to the WHO classes: underweight, normal, overweight, obese. The effects of BMI on outcomes (complications, 30-days mortality, DFS and OS) were evaluated with a linear regression model, and with a logistic regression model for binary endpoints. In overweight and obese patients, operative time increased with BMI value. Operating room time increased by 5.54 minutes (S.E. = 1.57) in overweight patients, and 33.12 minutes (S.E. = 10.26) in obese patients (P < 0.001). Compared to the other BMI classes, overweight patients were at the lowest risk of pulmonary, acute cardiac, surgical, major, and overall postoperative complications. In the overweight range, a BMI increase from 25 to 29.9 did not significantly affect the length of stay, nor the risk of any complications, except for renal complications (OR: 1.55; 95% CI: 1.07-2.24; P = 0.03), and it reduced the risk of prolonged air leak (OR: 0.8; 95% CI: 0.71-0.90; P < 0.001). 30-days mortality is higher in the underweight group compared to the others. We did not find any significant difference in DFS and OS. According to our results, obesity increases operating room time for VATS major lung resection. Overweight patients are at the lowest risk of pulmonary, acute cardiac, surgical, major, and overall postoperative complications following VATS resections. The risk of most postoperative complications progressively increases as the BMI deviates from the point at the lowest risk, towards both extremes of BMI values. Thirty days mortality is higher in the underweight group, with no differences in DFS and OS.

Factors Associated with Early Discharge after Thoracoscopic Lobectomy: Results from the Italian VATS Group Registry.

Objective. There are limited data for estimating the risk of early discharge following thoracoscopic lobectomy. The objective was to identify the factors associated with a short length of stay and verify the influence of these variables in uncomplicated patients. Methods. We reviewed all lobectomies reported to the Italian VATS Group between January 2014 and January 2020. Patients and perioperative characteristics were divided into two subgroups based on whether or not they met the target duration of stay (≤ or >4 days). The association between preoperative and intraoperative variables and postoperative length of stay (LOS) ≤4 days was assessed using a stepwise multivariable logistic regression analysis to identify factors independently associated with LOS and factors related to LOS in uncomplicated cases. Results. Among 10,240 cases who underwent thoracoscopic lobectomy, 37.6% had a hospital stay ≤4 days. Variables associated with LOS included age, hospital surgical volume, Diffusion Lung CO % (81 [69−94] vs. 85 [73−98]), Forced Expiratory Volume (FEV1) % (92 [79−106] vs. 96 [82−109]), operative time (180 [141−230] vs. 160 [125−195]), uniportal approach (571 [9%] vs. 713 [18.5%]), bioenergy sealer use, and pain control through intercostal block or opioids (p < 0.001). Except for FEV1 and blood loss, all other factors emerged significantly associated with LOS when the analysis was limited to uncomplicated patients. Conclusions. Demographic, clinical, and surgical variables are associated with early discharge after thoracoscopic lobectomy. This study indicates that these characteristics are associated with early discharge. This result can be used in association with clinical judgment to identify appropriate patients for fast-track protocols.

Bubbles-in-the-chamber vs digital screen in chest drainage: A blind analysis of compared postoperative air leaks evaluation.

BACKGROUND: Chest drainage systems are affected by intra and inter-observer variability and poor sensibility in detecting minimal or apparent air leaks. OBJECTIVES: Overcome intra and inter-observer variability in detecting air leaks. METHODS: After surgery, a single apical chest tube was connected to the Drentech™ PalmEVO device and air leaks were checked twice a day by observation of both bubbles-in-the-chamber and digital data. RESULTS: On a total of 624 observations, disagreement between digital and traditional systems was recorded in 60(9.6%) cases. In 25(21.4%) patients, a disagreement was recorded. Overall, the digital evaluation influenced clinical management in 13(52%). In 10(40%) patients with temporary discordant features, the presence of high pleural fluid output led to a progressive final concordance. CONCLUSIONS: Disagreement between traditional and digital systems in checking air leaks is not negligible. Digital systems could give advantages in making an objective assessment of air leaks, standardizing the timing of chest tube removal.

Multicenter randomized controlled trial comparing digital and traditional chest drain in a VATS pulmonary lobectomy cohort: interim analysis.

BACKGROUND: The usefulness of digital chest drain is still debated. We are carrying out a study to determine if the use of a digital system compared with a traditional system reduces the duration of chest drainage. To evaluate safety, benefit, or futility of this trial we planned the current interim analysis. METHODS: An interim analysis on preliminary data from ongoing investigator-initiated, multicenter, interventional, prospective randomized trial. Original protocol number: (NCT03536130). The interim main endpoint was overall complications; secondary endpoints were the concordance between the two primary endpoints of the RCT (chest tube duration and length of hospital stay). We planned the interim analysis when half of the patients have been randomised and completed the study. Data were described using mean and standard deviation or absolute frequencies and percentage. T-test for unpaired samples, Chi-square test, Poisson regression and absolute standardized mean difference (ASMD) were used. P-value < 0.05 was considered significant. RESULTS: From April 2017 to November 2018, out of 317 patients enrolled by 3 centers, 231 fulfilled inclusion criteria and were randomized. Twenty-two of them dropped out after randomization. Finally, 209 patients were analyzed: among them 94 used the digital device and 115 the traditional one. The overall postoperative complications were 35 (16.8%) including prolonged air leak (1.9%). Mean chest tube duration was 3.6 days (SD = 1.8), with no differences between two groups (p = 0.203). The overall difference between hospital stay and chest tube duration was 1.4 days (SD = 1.4). Air leak at first postoperative day detected by digital and traditional devices predicted increasing in tube duration of 1.6 day (CI 95% 0.8-2.5, p < 0.001) and 2.0 days (CI 95% 1.0-3.1, p < 0.001), respectively. CONCLUSIONS: This interim analysis supported the authors' will to continue with the enrollment and to analyze data once the estimated sample size will be reached. TRIAL REGISTRATION: Trial registration number NCT03536130 , Registered 24 May 2018 - Retrospectively registered.

Recommendations from the Italian intersociety consensus on Perioperative Anesthesa Care in Thoracic surgery (PACTS) part 2: intraoperative and postoperative care.

INTRODUCTION: Anesthetic care in patients undergoing thoracic surgery presents specific challenges that require a multidisciplinary approach to management. There remains a need for standardized, evidence-based, continuously updated guidelines for perioperative care in these patients. METHODS: A multidisciplinary expert group, the Perioperative Anesthesia in Thoracic Surgery (PACTS) group, was established to develop recommendations for anesthesia practice in patients undergoing elective lung resection for lung cancer. The project addressed three key areas: preoperative patient assessment and preparation, intraoperative management (surgical and anesthesiologic care), and postoperative care and discharge. A series of clinical questions was developed, and literature searches were performed to inform discussions around these areas, leading to the development of 69 recommendations. The quality of evidence and strength of recommendations were graded using the United States Preventive Services Task Force criteria. RESULTS: Recommendations for intraoperative care focus on airway management, and monitoring of vital signs, hemodynamics, blood gases, neuromuscular blockade, and depth of anesthesia. Recommendations for postoperative care focus on the provision of multimodal analgesia, intensive care unit (ICU) care, and specific measures such as chest drainage, mobilization, noninvasive ventilation, and atrial fibrillation prophylaxis. CONCLUSIONS: These recommendations should help clinicians to improve intraoperative and postoperative management, and thereby achieve better postoperative outcomes in thoracic surgery patients. Further refinement of the recommendations can be anticipated as the literature continues to evolve.

Recommendations from the Italian intersociety consensus on Perioperative Anesthesia Care in Thoracic surgery (PACTS) part 1: preadmission and preoperative care.

INTRODUCTION: Anesthetic care in patients undergoing thoracic surgery presents specific challenges that necessitate standardized, multidisciplionary, and continuously updated guidelines for perioperative care. METHODS: A multidisciplinary expert group, the Perioperative Anesthesia in Thoracic Surgery (PACTS) group, comprising 24 members from 19 Italian centers, was established to develop recommendations for anesthesia practice in patients undergoing thoracic surgery (specifically lung resection for cancer). The project focused on preoperative patient assessment and preparation, intraoperative management (surgical and anesthesiologic care), and postoperative care and discharge. A series of clinical questions was developed, and PubMed and Embase literature searches were performed to inform discussions around these areas, leading to the development of 69 recommendations. The quality of evidence and strength of recommendations were graded using the United States Preventative Services Task Force criteria. RESULTS: Recommendations for preoperative care focus on risk assessment, patient preparation (prehabilitation), and the choice of procedure (open thoracotomy vs. video-assisted thoracic surgery). CONCLUSIONS: These recommendations should help pulmonologists to improve preoperative management in thoracic surgery patients. Further refinement of the recommendations can be anticipated as the literature continues to evolve.

Modified transmanubrial osteomuscular sparing approach for resection of T1 vertebral tumor.

We report a technical modification of the classic transmanubrial osteomuscular sparing approach described by Grünenwald and Spaggiari for the treatment of a T1 vertebral tumor. The goal of the surgical treatment for spinal tumors of the cervico-thoracic area is to excise the vertebral tumor, reconstruct the spinal column, and place an internal fixation device to achieve immediate stabilization. The procedure was necessary for treating a patient who presented with an invasion of T1 vertebral body by multiple myeloma with initial neurological symptoms of epidural spinal cord compression. This approach requires a multidisciplinary team, essentially composed by the thoracic surgeon, who performs the anatomical dissection of the cervico-thoracic area, and the neurosurgeon, who performs the vertebrectomy and placement of a titanium prosthesis (Harm's cage). The operation was successful; the follow-up 6 months after the surgical procedure is normal.

Tracheal laceration after laser ablation of nodular goitre.

A tracheal perforation was discovered after Nd-YAG laser thermal ablation (LTA) of a thyroid nodule. The LTA is a relatively new method of treatment of thyroid nodules, which consists of delivering laser energy into the thyroid by means of two optical fibres. The patient presented with a multinodular goitre and initially refused surgery, then underwent an LTA of a thyroid nodule. Fifty days after the procedure she started to have symptoms related to a tracheal stenosis and, after tracheoscopy, a tracheal perforation was diagnosed and she underwent a total thyroidectomy plus tracheal repair. The results of the histological examination revealed a goitre with a focal area of papillary carcinoma. This particular complication is likely the first of its kind to be described after the LTA of a thyroid nodule.

Transmanubrial osteomuscular sparing approach: different indications.

The surgery of the cervico-thoracic inlet is a challenge for the thoracic surgeon. Several authors have described different approaches - with different degrees of invasiveness - to this anatomical area. We used the transmanubrial osteomuscular sparing approach described by Grünenwald and Spaggiari for six patients with five different indications: 1) left anterior Pancoast tumor; 2) glomus tumor originating from the inferior trunk (C8-T1 roots) of the right brachial plexus; 3) T1 vertebral tumor; 4) right internal jugular chain, Pirogoff confluence and subclavian artery metastatic lymph nodes from thyroid carcinoma; 5) chondrosarcoma of the first left rib. The results have been satisfactory from a surgical point of view, considering that the approach gave a good exposure of the operative field (especially at the cervical level), without cosmetic problems or functional limitations. In our experience, the transmanubrial osteomuscular sparing approach is a valid technique for the treatment of several kinds of tumors of the cervico-thoracic inlet, giving a good exposure of the operative field. In the case of anterior Pancoast tumors, the upper lobectomy may necessitate a further axillary thoracotomy, when fissural adherences are present.
