OBJECTIVE: Lung biopsies are sometimes performed in mechanically ventilated patients with acute hypoxemic respiratory failure (AHRF) of unknown etiology to guide patient management. While surgical lung biopsies (SLB) offer high diagnostic rates, they may also cause significant complications. Transbronchial forceps lung biopsies (TBLB) are less invasive but often produce non-contributive specimens. Transbronchial lung cryobiopsies (TBLC) yield specimens of potentially better quality than TBLB, but due to their novel implementation in the intensive care unit (ICU), their accuracy and safety are still unclear.
OBJECTIVE: Our main objective was to evaluate the risk of adverse events in patients with AHRF following the three biopsy techniques. Our secondary objectives were to assess the diagnostic yield and associated modifications of patient management of each technique.
METHODS: We conducted a retrospective cohort study comparing TBLC, TBLB, and SLB in mechanically ventilated patients with AHRF.
METHODS: The primary outcome was the proportion of patients with at least one complication, and secondary outcomes included complication rates, diagnostic yields, treatment modifications, and mortality.
RESULTS: Of the 26 patients who underwent lung biopsies from 2018 to 2022, all TBLC and SLB patients and 60% of TBLB patients had at least one complication. TBLC patients had higher unadjusted numbers of total and severe complications, but also worse Sequential Organ Failure Assessment scores and P/F ratios. A total of 25 biopsies (25/26, 96%) provided histopathological diagnoses, 88% (22/25) of which contributed to patient management. ICU mortality was high for all modalities (63% for TBLC, 60% for TBLB and 50% for SLB).
CONCLUSIONS: All biopsy methods had high diagnostic yields and the great majority contributed to patient management; however, complication rates were elevated. Further research is needed to determine which patients may benefit from lung biopsies and to determine the best biopsy modality.

BACKGROUND: Video-assisted thoracoscopic surgery (VATS) often induces significant postoperative pain, potentially leading to chronic pain and decreased quality of life. This study aimed to evaluate the acetaminophen/ibuprofen combination effectiveness in reducing analgesic requirements and pain intensity in patients undergoing VATS.
METHODS: This is a double-blinded randomized controlled trial.
METHODS: Adult patients scheduled for elective VATS for lung resection were randomized to receive either intravenous acetaminophen and ibuprofen (intervention group) or 100 mL normal saline (control group). Treatments were administered post-anesthesia induction and every 6 h for three cycles. The primary outcome was total analgesic consumption at 24 h postoperatively. Secondary outcomes were cumulative analgesic consumption at 2 and 48 h; analgesic-related side effects at 2, 24, and 48 h; quality of recovery at 24 h and 48 h postoperatively; pain intensity at rest and during coughing; and rescue analgesics use. Chronic postsurgical pain (CPSP) was assessed through telephone interviews 3 months postoperatively.
RESULTS: The study included 96 participants. The intervention group showed significantly lower analgesic consumption at 24 h and 48 h postoperatively (24 h: median difference: - 100 µg equivalent intravenous fentanyl [95% confidence interval (CI) - 200 to - 5 μg], P = 0.037; 48 h: median difference: - 140 μg [95% CI - 320 to - 20 μg], P = 0.035). Compared to the controls, the intervention group exhibited a significantly lower quality of recovery 24 h post-surgery, with no significant difference at 48 h. All pain scores except for coughing at 48 h post-surgery were significantly lower in the intervention group compared to the controls. No significant differences were observed between the groups in postoperative nausea and vomiting occurrence, hospital stay length, and CPSP.
CONCLUSIONS: Perioperative administration of acetaminophen/ibuprofen significantly decreased analgesic needs in patients undergoing VATS, providing an effective postoperative pain management strategy, and potentially minimizing the need for stronger analgesics.

BACKGROUND: Regional block, such as thoracic epidural analgesia (TEA), thoracic paravertebral block (TPVB), or serratus anterior plane block (SAPB) has been recommended to reduce postoperative opioid use in recent guidelines, but the optimal options for intraoperative opioid minimization remain unclear. The aim of this study was to evaluate the intraoperative opioids-sparing effects of three regional blocks (TEA, TPVB, and SAPB) in patients undergoing video-assisted thoracoscopic surgery (VATs).
METHODS: This was a retrospective study of the adults undergoing VATs at a tertiary medical center between January 2020 and February 2022. According to the type of regional block used, patients were classified into 4 groups: GA group (general anesthesia without any regional block), TEA group (general anesthesia combined with TEA), TPVB group (general anesthesia combined with TPVB), and SAPB group (general anesthesia combined with SAPB). Cases were matched with a 1:1:1:1 ratio for analysis by age, sex, ASA physical status, and operation duration. The primary outcome was the total intraoperative opioid consumption standardized to Oral Morphine Equivalents (OME). Multivariable linear regression was used to estimate the association of the three regional blocks with the OME.
RESULTS: A total of 2159 cases met the eligibility criteria. After matching, 168 cases (42 in each group) were included in analysis. Compared with GA without any reginal block, the use of TEA, TPVB, and SAPB reduced the median of intraoperative OME by 78.45 mg (95% confidence interval [CI], -141.34 to -15.56; P = 0.014), 94.92 mg (95% CI, -154.48 to -35.36; P = 0.020), and 11.47 mg (95% CI, -72.07 to 49.14; P = 0.711), respectively.
CONCLUSIONS: The use of TEA or TPVB was associated with an intraoperative opioid-sparing effect in adults undergoing VATs, whereas the intraoperative opioid-sparing effect of SAPB was not yet clear.

Background: Video-assisted thoracoscopic surgery is a widely recommended treatment for empyema in advanced stages. However, only a few studies have evaluated prognostic factors among patients with empyema who underwent video-assisted thoracoscopic surgery. Furthermore, no studies have evaluated predictors of direct discharge home. Patients and Methods: This multicenter retrospective cohort study included 161 patients with empyema who underwent video-assisted thoracoscopic surgery in five acute-care hospitals. The primary outcome was the probability of direct discharge home. The secondary outcome was the length of hospital stay after surgery. We broadly assessed pre-operative factors and performed univariable logistic regression for the direct discharge home and univariable gamma regression for the length of hospital stay after surgery. Results: Of the 161 included patients, 74.5% were directly discharged home. Age (>70 years; -24.3%); altered mental status (-33.4%); blood urea nitrogen (>22.4 mg/dL; -19.4%); and pleural pH (<7.2; -17.6%) were associated with high probabilities of not being directly discharged home. Fever (15.2%) and albumin (> 2.7 g/dL; 20.2%) were associated with high probabilities of being directly discharged home. The median length of stay after surgery was 19 days. Age (>70 years; 6.2 days); altered mental status (5.6 days); purulence (2.7 days); pleural thickness (>2 cm; 5.1 days); bronchial fistula (14.6 days); albumin (>2.7 g/dL; 3.1 days); and C-reactive protein (>20 mg/dL; 3.6 days) were associated with a longer post-operation hospital stay. Conclusions: Physicians should consider using these prognostic factors to predict non-direct discharge to the home for patients with empyema.

BACKGROUND: Postoperative nausea and vomiting (PONV) is a common complication after general anaesthesia and is associated with morbidity and prolonged length of stay. Growing evidence suggest that opioid-free general anaesthesia (OFA) may reduce PONV in various surgical settings. We aim to evaluate the efficacy of OFA on the incidence of PONV compared with opioid-based anaesthesia among adults undergoing thoracoscopic surgery.
METHODS: This is a prospective, single-centre, randomised controlled trial comparing OFA and opioid-based anaesthesia for thoracoscopic surgery. A total of 168 adults will be randomised with a 1:1 ratio to receive either opioid-free anaesthesia or opioid-based anaesthesia. The primary outcome will be the incidence of PONV within 24 h after operation. The secondary outcomes will include the severity of PONV, quality of recovery, pain at rest, 6-min walking test, and health-related quality of life after operation.
CONCLUSIONS: The benefit-risk of OFA for patients after operation is contradictory in previous studies, so further study is required. This trial will focus on the effect of OFA on the incidence of PONV in patients undergoing thoracoscopic surgery. This trial adopts uniformed PONV and perioperative pain management, standardised randomised and blind, clear-cut inclusion and exclusion criteria, and standardised scales to assess the severity of PONV after surgery, the quality of postoperative recovery, and the health status at 6 months. The findings of this study will help to provide references to promote early recovery of patients after lung surgery.
BACKGROUND: ClinicalTrials.gov NCT05411159. Registered on 9 June 2022.

The use of a sealing device during video-assisted liver transection has gained a lot of popularity due to its advantages in operative and patient outcomes. However, it has some technical problems including tissue debris sticking to the instrument, excessive smoke production, and loss of pneumoperitoneum from suction. Herein, we describe a novel \'Waterfall\' technique that uses continuous irrigation of saline directly on the transection plane. This technique washes away tissue particles and smoke, clears the operative view, and improves the effectiveness of tissue sealing.

UNASSIGNED: Video-assisted thoracoscopic surgery (VATS) and robotic-assisted thoracoscopic surgery (RATS) are two viable options in patients undergoing lobectomy for non-small cell lung cancer (NSCLC); however, the debate on which one is superior is unceasing.
UNASSIGNED: PubMed and Scopus databases were queried for studies including patients who underwent either VATS or RATS lobectomy. This meta-analysis is in accordance with the recommendations of the PRISMA statement. Individual patient data on overall survival (OS) and disease-free survival (DFS) were extracted from Kaplan-Meier curves. One- and two-stage survival analyses, and random-effects meta-analyses were conducted.
UNASSIGNED: Ten studies met our eligibility criteria, incorporating 1,231 and 814 patients in the VATS and RATS groups, respectively. Patients who underwent VATS had similar OS compared with those who underwent RATS [hazard ratio (HR): 1.05, 95% confidence interval (CI): 0.88-1.27, P=0.538] during a weighted median follow-up of 51.7 months, and this was validated by the two-stage meta-analysis (HR: 1.27, 95% CI: 0.85-1.90, P=0.24, I2=68.50%). Regarding DFS, the two groups also displayed equivalent outcomes (HR: 1.07, 95% CI: 0.92-1.25, P=0.371) and this was once again validated by the two-stage meta-analysis (HR: 1.05, 95% CI: 0.85-1.30, P=0.67, I2=28.27%). Both RATS and VATS had similar postoperative complication rates, prolonged air leak, conversion to thoracotomy and operative times. RATS was found to be superior to VATS in terms of length of hospital stay and number of lymph nodes dissected.
UNASSIGNED: In patients undergoing lobectomy for NSCLC, VATS and RATS have equivalent overall and DFS at a median follow-up of 51.7 months.

UNASSIGNED: The Quality of Recovery-15 (QoR-15) questionnaire provides a multifaceted assessment of postoperative recovery, and the resulting score is recommended as an endpoint in clinical studies focused on postoperative pain. We aimed to investigate the correlation between the QoR-15 score and postoperative pain intensity in surgical patients.
UNASSIGNED: Adult patients who underwent video-assisted thoracoscopic surgery (VATS) for lung cancer resection and were enrolled in a prospective registry or in a previous prospective study were included in this study. Baseline and perioperative data, including the results of assessment using the Korean version of the QoR-15 (QoR-15K) questionnaire at 48 hours postoperatively, were collected from the database. Correlations between the QoR-15K total score, questionnaire dimensions, and postoperative pain intensity at 48 hours postoperatively were determined using the Spearman correlation coefficient (ρ).
UNASSIGNED: We analyzed a total of 137 eligible patients. Significant negative correlations were noted between the QoR-15K total score and pain intensity at rest (ρ = -0.45, 95% confidence interval [CI]: -0.57 - -0.31, P < 0.001) and during coughing (ρ = -0.55, 95% CI: -0.65 - -0.42, P < 0.001) at 48 hours postoperatively. The pain dimension and pain intensity at 48 hours postoperatively showed significant correlations with physical comfort, emotional state, and physical independence dimensions. Multivariable logistic regression revealed a significant negative association between the pain score at 24 hours postoperatively and good or excellent postoperative recovery.
UNASSIGNED: The results support the impact of postoperative pain on the overall postoperative quality of recovery in patients who underwent VATS for lung cancer resection. Moreover, the QoR-15K score may be considered as a primary endpoint in clinical studies on postoperative pain control.

UNASSIGNED: To explore the factors affecting the intraoperative conversion of video-assisted thoracoscopic surgery (VATS) to thoracotomy in patients with lung cancer.
UNASSIGNED: The clinical data of 80 patients with lung cancer in The Fourth Hospital of Hebei Medical University from May 2019 to December 2021 were retrospectively analyzed. The patients who were treated with VATS alone were included into thoracoscopy group (n= 40), and those who were intraoperatively converted from VATS to thoracotomy were included into conversion group (n= 40). The medical record data were collected, the influencing factors of intraoperative conversion from VATS to thoracotomy were analyzed, and the surgical indexes and postoperative complications were compared between the two groups.
UNASSIGNED: Multivariate regression model showed that tumor in the upper lobe, central lung cancer, history of pulmonary tuberculosis, pleural adhesion ≥ Grade-4 and maximum tumor diameter ≥ 35 mm were risk factors for patients with lung cancer undergoing conversion from VATS to thoracotomy (p< 0.05). In the conversion group, the surgical duration and hospital stay were longer, the intraoperative bleeding volume and thoracic drainage volume were larger, and the total incidence of postoperative complications was higher than those in the thoracoscopy group (p< 0.05).
UNASSIGNED: Conversion from VATS to thoracotomy may increase the risk of complications in patients with lung cancer. Tumor in the upper lobe, central lung cancer, history of pulmonary tuberculosis, high degree of pleural adhesion and large tumor diameter are risk factors for conversion from VATS to thoracotomy.
