Efficacy and complications of endoscopic thoracoscopic versus laparoscopic radical esophagectomy in esophageal cancer treatment: A retrospective study.

To evaluate the efficacy and postoperative complications of endoscopic thoracoscopic and laparoscopic radical esophagectomy compared to open surgery in esophageal cancer treatment. This retrospective study included 103 esophageal cancer patients admitted from August 2018 to March 2022, divided into observation (endoscopic surgery) and control (open surgery) groups. We compared intraoperative parameters, postoperative outcomes, immune function, and one-year overall survival (OS). Intraoperative bleeding volume, the retention time of chest tube, postoperative fasting time, and hospital stay in the observation group were smaller than those in the control group (P < .05). The differences were not statistically significant (P > .05) when comparing operative time, the number of intraoperative blood transfusion cases, and the rate of operating room extubation in these 2 groups. The differences were not statistically significant when comparing the amount of resected lymph nodes and the positive rate of incisal edge in these 2 groups (P > .05). There was no statistically significant difference in the complication rates such as pneumonia, pleural effusion, pneumothorax, pulmonary embolism, anastomotic fistula, the leakage of thoracic duct, the injury of RLN and arrhythmia in these 2 groups (P > .05). At 7 days postoperatively, the CD4+ and CD4+/CD8+ in the observation group and the control group were smaller than the preoperative ones in their same groups, and they were larger in the observation group than those in the control group (P < .05); There was no statistically significant difference on the CD8+ in the observation group and the control group at 7 days postoperatively compared with the preoperative ones in their same groups (P > .05). The 1-year postoperative OS rate was 81.63% (40/49) in the observation group and 72.22% (39/54) in the control group, and the difference was not statistically significant when comparing the OS rates of these 2 groups (P = .238, HR = 0.622, 95% CI = 0.279-1.385). Endoscopic thoracoscopic and laparoscopic esophagectomy offers less invasive treatment with significant short-term benefits and better preservation of immune function in esophageal cancer patients, making it a safe and effective surgical option.

Thoracoscopic three-port single versus multiple intercostal for radical resection of esophageal cancer: a retrospective analysis.

BACKGROUND: The purpose of this retrospective study was to compare the safety and feasibility of single-intercostal totally minimally invasive Ivor Lewis esophagectomy (MIIE) with those of multiple-intercostal MIIE. METHODS: Between January 2016 and December 2022, clinical data were collected for 528 patients who successfully underwent totally minimally invasive esophagectomy. Among these patients, 294 underwent MIIE, with 200 undergoing the single-intercostal approach and 94 undergoing the multiple-intercostal approach. Propensity score matching (PSM) was applied to the cohort of 294 patients. Subsequently, perioperative outcomes and other pertinent clinical data were analyzed retrospectively. RESULTS: A total of 294 patients were subjected to PSM, and 89 groups of patient data (178 persons in total) were well balanced and included in the follow-up statistics. Compared to the multiple intercostal group, the single intercostal group had a shorter operative time (280 min vs. 310 min; p < 0.05). Moreover, there was no significant difference in the incidence of major perioperative complications (p > 0.05). The total number of lymph nodes sampled (25.30 vs. 27.55, p > 0.05) and recurrent laryngeal nerve lymph nodes sampled on the both sides (p > 0.05) did not significantly differ. The single intercostal group had lower postoperative long-term usage of morphine (0,0-60 vs. 20,20-130; p < 0.01), total temporary addition (10,0-30 vs. 20,20-40; p < 0.01) and temporary usage in the first 3 days after surgery (0,0-15 vs. 10,10-20; p < 0.01) than did the multicostal group.There were no significant differences in age, sex, tumor location or extent of lymphadenectomy or in the clinical factors between the single-intercostal group (p > 0.05). CONCLUSIONS: Both techniques can be used for the treatment of esophageal cancer. Compared to multiple intercostal MIIE, the feasibility of which has been proven internationally, the single intercostal technique can also be applied to patients of different age groups and sexes and with different tumor locations. It can provide surgeons with an additional surgical option.

Comparison of postoperative analgesia by thoracoscopic-guided thoracic paravertebral block and thoracoscopic-guided intercostal nerve block in uniportal video-asssited thoracic surgery: a prospective randomized controlled trial.

BACKGROUND: Thoracoscopic-guided thoracic paravertebral nerve block (TG-TPVB) and thoracoscopic-guided intercostal nerve block (TG-INB) are two postoperative analgesia technology for thoracic surgery. This study aims to compared the analgesic effect of TG-TPVB and TG-INB after uniportal video-asssited thoracic surgery (UniVATS). METHODS: Fifty-eight patients were randomly allocated to the TG-TPVB group and the TG-INB group. The surgical time of nerve block, the visual analog scale (VAS) scores, the consumption of sufentanil and the number of patient-controlled intravenous analgesic (PCIA) presses within 24 h after surgery, the incidence of adverse reactions were compared between the two groups. RESULTS: The VAS scores were significantly lower during rest and coughing at 2, 6, 12, and 24 h in the TG-TPVB group than in the TG-INB group (P < 0.05). The consumption of sufentanil and the number of PCIA presses within 24 h after surgery were significantly lower in the TG-TPVB group than in the TG-INB group (P < 0.001).The surgical time of nerve block was significantly shorter in the TG-TPVB group than in the TG-INB group (P < 0.001). The incidence of bleeding at the puncture point was lower in the TG-TPVB group than that in the TG-INB group (P < 0.05). CONCLUSION: TG-TPVB demonstrated superior acute pain relieve after uniVATS, shorter surgical time and non-inferior adverse effects than TG-INB.

A case report of a bleeding case after removal of chest drain after lung surgery.

RATIONALE: Postoperative bleeding after lobectomy is relatively rare. By analyzing and discussing the case history and management of hemorrhagic shock caused by chest tube removal after lobectomy, we can achieve the purpose of preventing postoperative bleeding after thoracic surgery and reducing postoperative complications, which can help avoid the risk of second surgery, shorten the patient's hospital stay, reduce the cost of medical care, and improve the patient's quality of life. PATIENT CONCERNS: A case of bleeding from tube removal after lobectomy. The bleeding from chest drain removal on the 3rd day after thoracoscopic lobectomy resulted in hemorrhagic shock, which was stopped by thoracoscopic exploration again under active antishock, and there was no recurrence of bleeding after the operation, and the patient was discharged from the hospital after chest drain removal. DIAGNOSES: Enhanced computed tomography of the chest revealed a space-occupying lesion in the middle lobe of the right lung. INTERVENTIONS: Thoracoscopy was performed again on the condition of active anti-shock. OUTCOMES: On the third day after thoracoscopic lobectomy, the patient underwent removal of the chest drain and subsequently experienced hemorrhagic shock. Given the necessity of maintaining anti-shock measures, the patient was subjected to a second thoracoscopic exploration with the objective of halting the hemorrhage. Following this procedure, the patient did not present with any further episodes of bleeding. Subsequently, a new chest drain was placed, and once the drainage flow had diminished to an acceptable level, the chest drain was removed. The patient subsequently made a full recovery and was discharged from the hospital. LESSONS: Even if the safely inserted drain tube is removed, the thoracic surgeon must be aware of possible vascular bleeding.

Talc slurry versus thoracoscopic talc insufflation for malignant pleural effusion: a systematic review and meta-analysis.

OBJECTIVE: Talc pleurodesis is a widely used treatment option for malignant pleural effusion (MPE). However, the optimal form of administration remains controversial. Thus, we performed a systematic review and meta-analysis to assess the effectiveness of talc slurry (TS) in comparison with thoracoscopic talc insufflation/poudrage (TTI) for MPE treatment. METHODS: We searched PubMed, EMBASE, and Cochrane Library databases for studies that compared TS with TTI in patients with MPE. We used a random-effects model with a 95% CI to pool the data. Heterogeneity was assessed with I2 statistics. RESULTS: We included eight studies involving 1,163 patients, 584 of whom (50.21%) underwent TS. Pleurodesis failure rates were similar between the procedures (OR = 1.07; 95% CI: 0.56-2.06; p = 0.83; I2 = 62%); and 68% of patients (95% CI: 0.31-1.47; p = 0.33; I2 = 58%) had postoperative complications, which were lower in patients in the TS group than in the TTI group. In a subgroup analysis considering only randomized clinical trials, the failure rate was significantly lower in the TS treatment group (OR = 0.62; 95% CI: 0.42-0.90; p = 0.01; I2 = 0%). Similarly, dyspnea was less common in the TS group (OR = 0.74; 95% CI: 0.41-1.34; p = 0.32; I2 = 55%). Adverse effects were reported in 86 patients, and no significant difference was seen between the TS and TTI groups: empyema (OR = 1.43; 95% CI: 0.36-5.64; p = 0.86; I2 = 0%), pain (OR = 1.22 (95% CI: 0.67-2.21; p = 0.51; I2 = 38%), and pneumonia (OR = 1.15; 95% CI: 0.30-4.46; p = 0.86; I2 = 27%). CONCLUSIONS: Our findings suggest that TS is an effective treatment for MPE, with no significant increase in adverse events. Results suggest equivalent efficacy and safety for both procedures.

Effects of starting one lung ventilation and applying individualized PEEP right after patients are placed in lateral decubitus position on intraoperative oxygenation for patients undergoing thoracoscopic pulmonary lobectomy: study protocol for a randomized controlled trial.

BACKGROUND: For patients receiving one lung ventilation in thoracic surgery, numerous studies have proved the superiority of lung protective ventilation of low tidal volume combined with recruitment maneuvers (RM) and individualized PEEP. However, RM may lead to overinflation which aggravates lung injury and intrapulmonary shunt. According to CT results, atelectasis usually forms in gravity dependent lung regions, regardless of body position. So, during anesthesia induction in supine position, atelectasis usually forms in the dorsal parts of lungs, however, when patients are turned into lateral decubitus position, collapsed lung tissue in the dorsal parts would reexpand, while atelectasis would slowly reappear in the lower flank of the lung. We hypothesize that applying sufficient PEEP without RM before the formation of atelectasis in the lower flank of the lung may beas effective to prevent atelectasis and thus improve oxygenation as applying PEEP with RM. METHODS: A total of 84 patients scheduled for elective pulmonary lobe resection necessitating one lung ventilation will be recruited and randomized totwo parallel groups. For all patients, one lung ventilation is initiated the right after patients are turned into lateral decubitus position. For patients in the study group, individualized PEEP titration is started the moment one lung ventilation is started, while patients in the control group will receive a recruitment maneuver followed by individualized PEEP titration after initiation of one lung ventilation. The primary endpoint will be oxygenation index measured at T4. Secondary endpoints will include intrapulmonary shunt, respiratory mechanics, PPCs, and hemodynamic indicators. DISCUSSION: Numerous previous studies compared the effects of individualized PEEP applied alone with that applied in combination with RM on oxygenation index, PPCs, intrapulmonary shunt and respiratory mechanics after atelectasis was formed in patients receiving one lung ventilation during thoracoscopic surgery. In this study, we will apply individualized PEEP before the formation of atelectasis while not performing RM in patients allocated to the study group, and then we're going to observe its effects on the aspects mentioned above. The results of this trial will provide a ventilation strategy that may be conductive to improving intraoperative oxygenation and avoiding the detrimental effects of RM for patients receiving one lung ventilation.

Robot-assisted minimally invasive oesophagectomy versus thoracoscopic approach: multi-institutional study on short-term outcomes.

BACKGROUND: Robot-assisted minimally invasive oesophagectomy and conventional minimally invasive oesophagectomy are superior to open techniques. However, few studies have directly compared the outcomes of the two minimally invasive approaches. METHODS: A retrospective study of patients from six medical centres with oesophageal squamous cell carcinoma who underwent minimally invasive oesophagectomy between 2015 and 2022. Perioperative outcomes were compared after applying inverse probability of treatment weighting. RESULTS: The study included 577 patients (robot-assisted minimally invasive oesophagectomy: 206; conventional minimally invasive oesophagectomy: 371). After applying inverse probability of treatment weighting, robot-assisted minimally invasive oesophagectomy was found to yield a higher number of mediastinal nodes compared with conventional minimally invasive oesophagectomy (14.86 versus 12.66, P = 0.017). Robot-assisted minimally invasive oesophagectomy was notably effective in retrieving upper mediastinal left recurrent laryngeal nerve nodes, averaging 1.97 nodes versus 1.14 nodes harvested by conventional minimally invasive oesophagectomy (P < 0.001). This was coupled by a significant decrease in nerve palsy rates (13.9% versus 22.8%, P = 0.020). A significantly larger percentage of patients in the robot-assisted minimally invasive oesophagectomy group had an uncomplicated postoperative course (51.8% versus 34%, P < 0.001). Robot-assisted minimally invasive oesophagectomy also led to a reduction in pneumonia rates (8.6% versus 15.2%, P = 0.041) and was linked to a shorter length of stay (length of stay; 16.64 versus 21.14 days, P = 0.007). The advantage of robot-assisted minimally invasive oesophagectomy in reducing the length of stay was especially pronounced in patients with a high Charlson co-morbidity index (≥2, mean difference 8.46 days; P = 0.0069) and those who underwent neoadjuvant therapy (mean difference 5.63 days; P < 0.001). CONCLUSION: In oesophageal squamous cell carcinoma, the use of robot-assisted minimally invasive oesophagectomy led to fewer cases of pneumonia and faster recovery compared with conventional minimally invasive oesophagectomy. Additionally, robot-assisted minimally invasive oesophagectomy significantly improved the feasibility and safety of performing lymph node dissection along the recurrent laryngeal nerve.

Single-centre observational study of the safety and efficacy of thoracoscopy under local anaesthesia for the management of thoracic infections.

OBJECTIVES: Thoracoscopy under local anaesthesia is widely performed to diagnose malignancies and infectious diseases. However, few reports have described the use of this procedure for diagnosing and treating intrathoracic infections. This study aimed to evaluate the safety and efficacy of thoracoscopy under local anaesthesia for the management of intrathoracic infections. RESULTS: Data from patients who underwent thoracoscopy procedures performed by chest physicians under local anaesthesia at our hospital between January 2018 and December 2023 were retrospectively reviewed. We analysed their demographic factors, reasons for the examinations, diseases targeted, examination lengths, anaesthetic methods used, diagnostic and treatment success rates, as well as any adverse events. Thirty patients were included. Of these, 12 (40%) had thoracoscopies to diagnose infections, and 18 (60%) had them to treat pyothorax. In terms of diagnosing pleurisy, the causative microorganism of origin was identified via thoracoscopy in only three of 12 (25.0%) patients. For diagnosing pyothorax, the causative microorganism was identified in 7 of 18 (38.9%) patients. Methicillin-resistant Staphylococcus aureus was the most common causative microorganism identified. The treatment success rates were very high, ranging between 94.4 and 100%, whereas the identification rate of the causative microorganisms behind infections was low, ranging between 25.0 and 38.9%. The most frequent adverse events included perioperative hypoxaemia and pain. There were two (6.7%) serious adverse events of grade ≥ 3, but none resulted in death. CONCLUSIONS: The efficacy of managing intrathoracic infections through thoracoscopy under local anaesthesia is commendable. Nonetheless, the diagnostic accuracy of the procedure, regarding the precise identification of the causative microorganisms responsible for intrathoracic infections, persists at a notably low level, presenting a substantial clinical hurdle.

Diagnostic yields and safety of thoracoscopic cryobiopsies in Japan: A single-center retrospective observational study.

BACKGROUND: Thoracoscopy is useful for diagnosing unexplained pleural effusions. A sufficient specimen volume is often difficult to obtain using forceps biopsies (FBs) but can be obtained with pleural cryobiopsies (CBs). This study aimed to assess the utility and safety of CB during thoracoscopy in the Japanese population. METHODS: Patients who underwent thoracoscopic CBs at the Japanese Red Cross Medical Center between January 2017 and August 2023 were included in the study. Data were retrospectively analyzed, including clinical data, thoracoscopic findings, specimen size, diagnostic yield, and complications. The number of collected specimens and the freezing time were left to the discretion of the attending physician. RESULTS: Twenty-six patients underwent thoracoscopic CB. Specimens obtained by CB were larger than those obtained by FB. Primary lung cancer was the most common cause of pleural effusion, followed by malignant pleural mesothelioma. CB contributed to the diagnosis in 24 of 26 cases (92.3%) and FB contributed to the diagnosis in 11 of 18 cases (61.1%). Severe fibrosis could be diagnosed in all 3 cases by CB, but not by FB. The common complications of CB included bleeding at the biopsy site and atelectasis, but no severe complications occurred. CONCLUSIONS: The utility and safety of thoracoscopic CB for diagnosing pleural effusions in Japan were verified. The diagnostic yield, specimen size, and safety profile of CB support the diagnostic utility of this method.

Thoracic Musculoskeletal Deformities Following Surgical Treatment of Esophageal Atresia - Thoracoscopic Versus Open Approach: A Retrospective Two Centers Cohort Study.

INTRODUCTION: Thoracic musculoskeletal deformities are significant complications following open correction of esophageal atresia (EA) during long-term follow-up. We aimed to compare the frequency and severity of thoracic musculoskeletal deformities after open and thoracoscopic repair of EA. We hypothesized that fewer deformities would occur following the less invasive thoracoscopic approach. METHODS: This retrospective study analyzed patients treated at two pediatric surgery departments in Poland between 2005 and 2021. The patient groups differed in surgical approach, operative techniques, indications for multi-staged surgery, and postoperative complications. The study encompassed all types of EA/TEF. The first group comprised 68 patients who underwent thoracoscopic esophageal atresia repair (Wroclaw), while the second group involved 44 patients who underwent open repair (Warsaw). Clinical data were retrospectively reviewed, with results considered significant at p < 0.05. RESULTS: The median age at examination was 6 years in the thoracoscopy group and 5.5 years in the thoracotomy group. In the thoracoscopy group, 53 out of 68 patients (77.9%) and in the thoracotomy group - 35 out of 44 patients (79.5%) were treated in one stage. The incidence of thoracic musculoskeletal deformities was significantly lower in the thoracoscopy group (1.5%) compared to the thoracotomy group (34.1%, p < 0.001). Scoliosis occurred significantly more often after thoracotomy (13.6% vs 1.5%, p = 0.016). There was no rib fusion (0% vs 37.1%, p < 0.001) and no scoliosis of =>20° (0% vs 6.8%, p = 0.058) after thoracoscopy. The coincidence of rib fusion and scoliosis was significant (9.1%, p = 0.022) for the open approach. In the thoracotomy group, multi-staged surgery and more frequent reoperations due to major complications were significantly associated with an increased occurrence of deformities. None of the patients after thoracoscopic multi-stage or complicated EA/TEF repair developed scoliosis. CONCLUSIONS: The frequency and severity of thoracic musculoskeletal deformities were significantly lower after the thoracoscopic approach. Thoracoscopy may be a more advantageous and preferred surgical approach for the EA/TEF treatment, although further randomized, controlled studies are necessary. Post-thoracotomy scoliosis may progress to a severity requiring surgery.

Protecting the non-operative lobe/s of the operative lung can reduce the pneumonia incidence after thoracoscopic lobectomy: a randomised controlled trial.

Lung isolation usually refers to the isolation of the operative from the non-operative lung without isolating the non-operative lobe(s) of the operative lung. We aimed to evaluate whether protecting the non-operative lobe of the operative lung using a double-bronchial blocker (DBB) with continuous positive airway pressure (CPAP) could reduce the incidence of postoperative pneumonia. Eighty patients were randomly divided into two groups (n = 40 each): the DBB with CPAP (Group DBB) and routine bronchial blocker (Group BB) groups. In Group DBB, a 7-Fr BB was placed in the middle bronchus of the right lung for right lung surgery and in the inferior lobar bronchus of the left lung for left lung surgery. Further, a 9-Fr BB was placed in the main bronchus of the operative lung. In Group BB, routine BB placement was performed on the main bronchus on the surgical side. The primary endpoint was the postoperative pneumonia incidence. Compared with Group BB, Group DBB had a significantly lower postoperative pneumonia incidence in the operative (27.5% vs 5%, P = 0.013) and non-operative lung (40% vs 15%) on postoperative day 1. Compared with routine BB use for thoracoscopic lobectomy, using the DBB technique to isolate the operative lobe from the non-operative lobe(s) of the operative lung and providing CPAP to the non-operative lobe(s) through a BB can reduce the incidence of postoperative pneumonia in the operative and non-operative lungs.

Network evolution of core symptoms after lung cancer thoracoscopic surgery:A dynamic network analysis.

OBJECTIVES: To investigate relationships between various symptoms occurring 1-2 and 5-6 days following days after thoracoscopic surgery, to identify core symptoms, and to monitor changes in core symptoms over time following lung cancer thoracoscopic surgery. METHODS: We evaluated symptoms using the Anderson Symptom Scale (Chinese version) and the Lung Cancer-Specific Symptoms Template in 214 lung cancer patients hospitalized in the Department of Thoracic Surgery of a provincial hospital in Jiangsu Province from March 2023 to September 2023. Data was collected at 1-2 days and 5-6 days postoperatively. Symptom networks were constructed for each time point, and centrality indicators were analyzed to identify core symptoms while controlling for influencing factors. RESULTS: According to the network analysis, fatigue (rs = 26.00、rc = 0.05、rb = 1.02) had the highest strength, closeness, and betweenness in the symptom network 1-2 days after lung cancer surgery. At 5-6 days after surgery, shortness of breath (rs = 27.00) emerged as the symptom with the highest strength, fatigue (rc = 0.04) had the highest closeness, and cough (rb = 1.08) ranked highest in betweenness within the symptom network. CONCLUSION: Fatigue stands out as the most core symptom in the network 1-2 days after lung cancer surgery. Shortness of breath, fatigue and cough are the most core symptoms in the symptom network 5-6 days after surgery. Therefore, clinical staff can improve the postoperative symptom experience of lung cancer patients by developing symptom management programmes tailored to these core symptoms.

Chest Wall Dermatitis Patterns Following Thoracoscopic Intercostal Nerve Cryoablation for Surgical Correction of Pectus Excavatum.

BACKGROUND: Intercostal nerve cryoablation (INC) has been shown to reduce postoperative pain and length of stay following surgical correction of pectus excavatum (SCOPE). Some patients have developed chest wall dermatological symptoms after INC that can be mistaken for metal allergy or infection. The purpose of this study is to report the symptoms, severity, incidence, and treatment of post-cryoablation dermatitis. METHODS: A retrospective single institution review was performed for patients who underwent SCOPE with and without INC between June 2016 and March 2023 to assess for incidence of postoperative dermatological findings. Characteristics associated with these findings were evaluated. RESULTS: During study period, 383 patients underwent SCOPE, 165 (43.1%) without INC and 218 (56.9%) with. Twenty-three (10.6%) patients who received INC developed exanthems characteristic of post-cryoablation dermatitis with two distinct phenotypes identified. No patients who underwent SCOPE without INC developed similar manifestations. Early dermatitis, characterized by a painless, erythematous, and blanching rash across the anterior thorax, was observed in 16 patients, presenting on median postoperative day 6.0 [IQR 6.0-8.5], with median time to resolution of 23.0 [IQR 12-71.0] days after symptom onset. Late dermatitis, characterized by hyperpigmentation spanning the anterior thorax, was observed in 7 patients, presenting on median postoperative day 129.0 [IQR 84.5-240.0], with median time to resolution of 114.0 [IQR 48.0-314.3] days. CONCLUSION: This is the first report of dermatological manifestations following SCOPE with INC, a phenomenon of unknown etiology and no known long-term sequela. In our experience, it is self-resolving and lacks systemic symptoms suggesting observation alone is sufficient for resolution. LEVEL OF EVIDENCE: IV.

Evaluating the safety of intraprocedural chest tube removal during medical thoracoscopy.

BACKGROUND: Medical Thoracoscopy (MT) is a diagnostic procedure during which after accessing the pleural space the patient's negative-pressure inspiratory efforts draw atmospheric air into the pleural cavity, which creates a space to work in. At the end of the procedure this air must be evacuated via a chest tube, which is typically removed in the post-anesthesia care unit (PACU). We hypothesized that its removal intra-operatively is safe and may lead to lesser post-operative pain in comparison to its removal in the PACU. METHODS: A retrospective review was conducted of all the MT with intraprocedural chest tube removal done between 2019 to 2023 in adult patients in a single center in New York, NY by interventional pulmonology. RESULTS: A total of 100 MT cases were identified in which the chest tube was removed intra-operatively. Seventy-seven percent of cases were performed as outpatient and all these patients were discharged on the same day. Post procedure ex-vacuo pneumothorax was present in 42% of cases. Sixty-five percent of cases had some post-procedure subcutaneous emphysema, none reported any complaint of this being painful, and no intervention was needed to relieve the air. Seventy-three percent required no additional analgesia in PACU. Of the 27% that required any form of analgesia, 59% required no additional analgesia beyond the first 24 h. CONCLUSIONS: Intraprocedural CT removal for MT is safe and may decrease utilization of additional analgesia post procedure. Further prospective studies are necessary to validate these conclusions.

Effects of nonintubated thoracoscopic surgery on postoperative neurocognitive function: a randomized controlled trial.

OBJECTIVES: Postoperative neurocognitive disorder following thoracoscopic surgery with general anaesthesia may be linked to reduced intraoperative cerebral oxygenation and perioperative inflammation, which can potentially be exacerbated by mechanical ventilation. However, nonintubated thoracoscopic surgery, which utilizes regional anaesthesia and maintains spontaneous breathing, provides a unique model for studying the potential benefits of avoiding mechanical ventilation. This approach allows investigation into the impact on perioperative neurocognitive profiles, inflammatory responses and intraoperative cerebral oxygen levels. METHODS: In total, 110 patients undergoing thoracoscopic surgery were randomly equally assigned to the intubated group and the nonintubated group. Regional cerebral oxygenation was monitored during surgery. Serum neuroinflammatory biomarkers, including interleukin-6 and glial fibrillary acidic protein, were measured at baseline (before surgery) and 24 h after surgery. Postoperative complication severity was compared using the Comprehensive Complication Index. The primary outcome was perioperative changes in neurocognitive test score, which was assessed at baseline, 24 h and 6 months after surgery. RESULTS: Patients in the nonintubated group had higher neurocognitive test scores at 24 h (69.9 ± 10.5 vs 65.3 ± 11.8; P = 0.03) and 6 months (70.6 ± 6.7 vs 65.4 ± 8.1; P < 0.01) after surgery and significantly higher regional cerebral oxygenation over time during one-lung ventilation (P = 0.03). Patients in the intubated group revealed a significantly higher postoperative serum interleukin-6 level (group by time interaction, P = 0.04) and a trend towards a significantly higher serum glial fibrillary acidic protein level (group by time interaction, P = 0.11). Furthermore, patients in the nonintubated group had a significantly lower Comprehensive Complication Index (9.0 ± 8.2 vs 6.1 ± 7.1; P < 0.05). CONCLUSIONS: Nonintubated thoracoscopic surgery was associated with improved postoperative neurocognitive recovery, more stable intraoperative cerebral oxygenation, ameliorated perioperative inflammation and attenuated postoperative complication severity.

Effectiveness of acupuncture for postoperative gastrointestinal recovery in patients undergoing thoracoscopic surgery: a prospective randomized controlled study.

BACKGROUND: Postoperative gastrointestinal dysfunction (PGD) is one of the most common complications among patients who have undergone thoracic surgery. Acupuncture has long been used in traditional Chinese medicine to treat gastrointestinal diseases and has shown benefit as an alternative therapy for the management of digestive ailments. This study aimed to explore the therapeutic effectiveness of acupuncture as a means to aid postoperative recovery of gastrointestinal function in patients undergoing thoracoscopic surgery. METHODS: In total, 112 patients aged 18-70 years undergoing thoracoscopic surgery between 15 June 2022 and 30 August 2022 were randomized into two groups. Patients in the acupuncture group (AG) first received acupuncture treatment 4 h after surgery, and treatment was repeated at 24 and 48 h. Patients in the control group (CG) did not receive any acupuncture treatment. Both groups received the same anesthetic protocol. Ultrasound-guided thoracic paravertebral block (TPVB) was performed in the paravertebral spaces between T4 and T5 with administration of 20 mL of 0.33% ropivacaine. All patients received patient-controlled intravenous analgesia (PCIA) after surgery. RESULTS: Median time to first flatus [interquartile range] in the AG was significantly less than in the CG (23.25 [18.13, 29.75] vs 30.75 [24.13, 45.38] h, p < 0.001). Time to first fluid intake after surgery was significantly less in the AG, as compared with the CG (4 [3, 7] vs 6.5 [4.13, 10.75] h, p = 0.003). Static pain, measured by visual analog scale (VAS) score, was significantly different on the third day after surgery (p = 0.018). Dynamic pain VAS scores were lower in the AG versus CG on the first three postoperative days (p = 0.014, 0.003 and 0.041, respectively). CONCLUSION: Addition of acupuncture appeared to improve recovery of postoperative gastrointestinal function and alleviate posteoperative pain in patients undergoing thoracoscopic surgery. Acupuncture may represent a feasible strategy for the prevention of PGD occurrence. TRIAL REGISTRATION NUMBER: ChiCTR2200060888 (Chinese Clinical Trial Registry).

The Role of Multilevel Intercostal Nerve Block in Local Anesthetic Thoracoscopy.

BACKGROUND: Intercostal nerve block (ICNB) has long been used in thoracic surgery. Local anesthetic thoracoscopy (LAT) is performed under conscious sedation with local anesthesia at the port insertion site. This alone, however, does not anesthetize the parietal pleura from where biopsies are taken and patients can experience pain. OBJECTIVES: To compare LAT with multilevel ICNB versus standard care to determine whether it reduces pain during and post-LAT, its effect on analgesia use, the hospital length of stay (LOS), and related complications. METHODS: Prospective analysis of patients undergoing LAT between January and June 2021. In the ICNB group, levobupivacaine/xylocaine is administered at the angle of the rib immediately before LAT (up to 5 rib spaces). Visual Analog Score for pain (0 to 100 mm) was measured at 1 and 2 hours post-LAT and daily including analgesia use. RESULTS: Twenty patients (10 ICNB vs. 10 standard care group). The mean age is 68 years with 70% males. Visual Analog Score for pain in the ICNB group reduced by 55 mm at 1 and 2 hours post-LAT and 45 mm at day 1 ( P <0.05) (minimal clinically important difference >16 mm]. Median LOS was reduced by 50% in the ICNB group ( P <0.05). Paracetamol use reduced by 56% ( P <0.05). CONCLUSION: ICNB not only significantly reduces postprocedure pain but also reduces LOS.
