Transareolar Single-Port Needlescopic Thoracic Sympathectomy Under Intravenous Anesthesia Without Intubation: A Randomized Controlled Trial

Patient-reported outcomes of laryngeal mask anesthesia in thoracoscopic pulmonary wedge resection: A randomized controlled study

BACKGROUND

To assess the effectiveness and safety of laryngeal mask anesthesia (LMA) in thoracoscopic pulmonary wedge resection based on patient-reported outcomes (PROs).

METHODS

This randomized controlled trial included 107 patients who underwent thoracoscopic pulmonary wedge resection between June 2017 and December 2021 for pulmonary nodule or pulmonary bullae. In one group, LMA was applied for general anesthesia, and in the other group, endotracheal intubation (ETT) was used.

RESULTS

A total of 107 patients were included in the study. The symptom assessment based on PROs showed that the incidence of pharyngodynia, trachyphonia, and cough were lower in the LMA group, while the postoperative gastrointestinal reaction did not significantly differ between the two groups. The pain score and global satisfaction score were significantly better in the LMA group. The satisfaction degree of anesthesia and the surgical field did not significantly differ between the two groups. The anesthesia recovery time, indwelling days of chest catheter, and postoperative hospital stay of the LMA group were all shorter, while the operation time, intraoperative blood loss and lowest intraoperative oxygen saturation did not significantly differ between the two groups. The highest intraoperative partial pressure of CO₂ was significantly higher in the LMA group. The artery blood gas analysis after the operation did not significantly differ between the two groups.

CONCLUSION

Compared with ETT, the application of LMA may demonstrate promising advantages in airway management for thoracoscopic pulmonary wedge resection.

The Anesthesiologist's Perspective Regarding Non-intubated Thoracic Surgery: A Scoping Review

Non-intubated thoracic surgery (NITS) is a growing practice, alongside minimally invasive thoracic surgery. To date, only a consensus of experts provided opinions on NITS leaving a number of questions unresolved. We then conducted a scoping review to clarify the state of the art regarding NITS. The systematic review of all randomized and non-randomized clinical trials dealing with NITS, based on Pubmed, EMBASE, and Scopus, retrieved 665 articles. After the exclusion of ineligible studies, 53 were assessed examining: study type, Country of origin, surgical procedure, age, body mass index, American Society of Anesthesiologist's physical status, airway management device, conversion to orotracheal intubation and pulmonary complications rates and length of hospital stay. It emerged that NITS is a procedure performed predominantly in Asia, and certain European Countries. In China, NITS is more frequently performed for parenchymal resection surgery, whereas in Europe, it is mainly employed for pleural pathologies. The most commonly used device for airway management is the laryngeal mask. The conversion rate to orotracheal intubation is a~3%. The results of the scoping review seem to suggest that NITS procedures are becoming increasingly popular, but its role needs to be better defined. Further randomized clinical trials are needed to better define the role of the clinical variables possibly impacting on the technique effectiveness.

A comparison of non-intubated video-assisted thoracic surgery with spontaneous ventilation and intubated video-assisted thoracic surgery: a meta-analysis based on 14 randomized controlled trials

Background

Video-assisted thoracic surgery (VATS) generally involves endotracheal intubation under general anesthesia. However, inevitably, this may cause intubation-related complications and prolong the postoperative recovery process. Gradually, non-intubated video-assisted thoracic surgery (NIVATS) is increasingly being utilized. However, its safety and efficacy remain controversial.

Methods

Randomized controlled trials (RCTs) published up to August 2020 were selected from the Cochrane Library, Web of Science, PubMed, Embase, and ClinicalTrials.gov databases and included in this study according to the inclusion criteria. Two reviewers screened these RCTs and independently extracted the relevant data. After assessing the risk of bias in these RCTs, a meta-analysis was performed using Review Manager 5.3. Pooled data were meta-analyzed using a random-effects model.

Results

Meta-analysis data demonstrated that the mean difference (MD) in the length of hospital stay between non-intubated patients and intubated patients was −1.41 days, with a 95% confidence interval (CI) of −2.47 to −0.34 (P=0.01). The visual analogue scale (VAS) score between the two groups showed a MD of −0.34 (95% CI: −0.58 to −0.10; P=0.006). Patients who underwent NIVATS presented with lower rates of overall complications [odds ratio (OR) 0.41; 95% CI: 0.25 to 0.67; P=0.0004], air leak (OR 0.45; 95% CI: 0.24 to 0.87; P=0.02), pharyngeal discomfort (OR 0.08; 95% CI: 0.04 to 0.17; P<0.00001), hoarseness (OR 0.06; 95% CI: 0.02 to 0.21; P<0.00001), and gastrointestinal reactions (OR 0.23; 95% CI: 0.10 to 0.53; P=0.0005) compared to intubated patients. The anesthesia satisfaction scores in the NIVATS group were significantly higher than those of the VATS group (MD 0.50; 95% CI: 0.12 to 0.88; P=0.009). However, there were no statistically significant differences in the length of operation time (MD 0.90 hours; 95% CI: −0.23 to 2.03; P=0.12) and surgical field satisfaction (1 point) (OR 0.73; 95% CI: 0.34 to 1.59; P=0.43) between the two groups.

Conclusions

NIVATS is a safe and feasible form of intervention that can reduce the postoperative pain and complications of various systems and shorten hospital stay duration without prolonging the operation time.

Transareolar single-port endoscopic thoracic sympathectomy with a flexible endoscope for primary palmar hyperhidrosis: a prospective randomized controlled trial

Background

Transareolar single-port endoscopic thoracic sympathectomy (ETS) with a flexible endoscope has rarely been reported. This study assessed the performance of this novel minimally invasive technique for primary palmar hyperhidrosis (PPH).

Methods

From January 2019 to September 2019, 118 males with severe PPH requiring single-port and bilateral ETS were randomly allocated to undergo transareolar ETS using a flexible endoscope (group A, n=58) or transaxillary ETS using a 5 mm thoracoscope (group B, n=60).

Results

Both groups had similar patient characteristics. All procedures were performed successfully, with no mortality or conversion to open surgery. All patients had dry and warm palms immediately after surgery. Compared with group B, group A had a significantly shorter median incision length [5.1 (5.0–5.2) vs. 10.9 (10.8–11.9) mm; P<0.001], and significantly lower median postoperative pain score [1 (1.0–2.0) vs. 3 (3.0–4.0); P<0.001]. There were no differences between the two groups in operative time, palmar temperature increase, and transient postoperative sweating. After complete follow-up, group A had a significantly higher median cosmetic score than group B [4.0 (3.0–4.0) vs. 3.0 (3.0–3.0); P<0.001]. There were no differences between the two groups regarding symptom resolution, compensatory hyperhidrosis, and satisfaction score. No patient reported residual pain or symptom recurrence.

Conclusions

Transareolar single-port ETS with a flexible endoscope is safe, effective, and minimally invasive with a small incision, minimal pain, and excellent cosmetic results. This novel procedure is suitable for routine treatment of PPH in males.

Contralateral spontaneous rupture of the esophagus following severe emesis after non-intubated pulmonary wedge resection

Background

Non-intubated thoracoscopic lung surgery has been reported to be technically feasible and safe. Spontaneous rupture of the esophagus, also known as Boerhaave’s syndrome (BS), is rare after chest surgery.

Case presentation

A 60-year-old female non-smoker underwent non-intubated uniportal thoracoscopic wedge resection for a pulmonary nodule. Ultrasound-guided serratus anterior plane block was utilized for postoperative analgesia. However, the patient suffered from severe emesis, chest pain and dyspnea 6 h after the surgery. Emergency chest x-ray revealed right-sided hydropneumothorax. BS was diagnosed by chest tube drainage and computed tomography. Besides antibiotics and tube feeding, a naso-leakage drainage tube was inserted into the right thorax for pleural evacuation. Finally, the esophagus was healed 40d after the conservative treatment.

Conclusions

Perioperative antiemetic therapy is an indispensable item of fast-track surgery. Moreover, BS should be kept in mind when the patients complain of chest distress following emesis after thoracic surgery.

Single-Instrument Thoracic and Abdominal Surgery in Children: Minimizing Minimally Invasive Surgery

Introduction: The use of single-port surgery is widely accepted in pediatric surgery, but the majority of reports are on its use for appendectomy or inguinal hernia repair using multiple instruments. The aim of this report is to demonstrate that both thoracic and abdominal single-instrument procedures are feasible and safe in children. Materials and Methods: The following cases were managed in our department for the past 12 months. Two types of telescopes (10- and 5-mm) with inbuilt working channels were used in all cases. Results: The 10-mm endoscope with a 6-mm inbuilt channel was used to partially reduce and then exteriorize an intussusception secondary to Meckel's diverticulum in a 9-year-old boy, to reduce a left ovarian torsion in a 8 year-old girl, and to perform a thoracoscopic exploration and lung decortication in a 16 year-old girl with empyema. A 5-mm endoscope with a 3-mm working channel was used to perform bilateral 2-level thoracic sympathotomy in a 13-year-old girl with palmar primary hyperhidrosis. There were no perioperative complications and follow-up was uneventful in all patients. Conclusion: Minimally invasive surgery is well established at present. Thoracic and abdominal single-port single-instrument procedures are safe and effective in children. This is a unique report on single-port single-instrument use in four completely different procedures and the first to describe its usage for thoracoscopic sympathotomy in children. Increasing technology development, allied to surgeons' skills, is crucial to worldwide adoption of this surgical modality.

Management Strategies Of Palmar Hyperhidrosis: Challenges And Solutions

Palmar hyperhidrosis is a potentially disabling condition for which management remains a therapeutic challenge. Given the significant impact on quality of life, various treatment options are available, ranging from topical agents and medical devices to systemic therapies and surgical interventions. Nonsurgical approaches, i.e. topical antiperspirants, botulinum toxin injections, iontophoresis, and systemic agents, are all supported by the current literature. Patients with mild-to-moderate disease can often benefit from topical therapies only. As disease severity progresses, systemic oral medication, such as anticholinergic drugs, usually becomes necessary. Last-line surgical approaches (sympathetic denervation) should be reserved for severe refractory cases. Recently, therapeutic strategies have been evolving with several new agents emerging as promising alternatives in clinical trials. In practice, however, each modality comes with its own benefits and risks. An individual therapeutic ladder is generally recommended, taking into account disease severity, benefit-to-risk profile, treatment cost, patient preference, and clinician expertise. This review will provide an update on current and emerging concepts of management for excessive hand sweating to help clinicians optimize therapeutic decision-making.

Non-intubated video-assisted thoracoscopic surgery vs. intubated video-assisted thoracoscopic surgery for thoracic disease: a systematic review and meta-analysis of 1,684 cases

Background

Non-intubated video-assisted thoracoscopic surgery (NIVATS) has been increasingly used in lobectomy, bullectomy, wedge resection, lung volume reduction, sympathectomy and talc pleurodesis, which may reduce postoperative complications. However, the benefits of non-intubated and intubated methods of VATS remain controversial.

Methods

We comprehensively searched PubMed, Web of Science, Embase and the Cochrane Library, and performed a systematic review to assess the two techniques. Random and fixed-effects meta-analytical models were used based on the low between-study heterogeneity. Study quality, publication bias, and heterogeneity were assessed.

Results

Compared to intubated methods, NIVATS had a lower postoperative complications rate [odds ratio (OR): 0.63; 95% confidence interval (CI), 0.46-0.86; P<0.01], shorter global in-operating time [weighted mean difference (WMD): -35.96 min; 95% CI, -48.00 to -23.91; P<0.01], shorter hospital stay (WMD: -1.35 days; 95% CI, -1.72 to -0.98; P<0.01), shorter anesthesia time (WMD: -7.29 min; 95% CI, -13.30 to -1.29; P<0.01), shorter chest-tube placement time (WMD: -1.04 days; 95% CI, -1.75 to -0.33; P<0.01), less chest pain (WMD: -1.31; 95% CI, -2.45 to -0.17; P<0.05) and lower perioperative mortality rate (OR: 0.13; 95% CI, 0.02-0.99; P=0.05).

Conclusions

NIVATS is a safe, efficient and feasible technique for thoracic surgery and may be a better alternative procedure owing to its advantage in reducing postoperative complications rate, hospital stay, and chest pain.

Raynaud's phenomenon: Current concepts

Raynaud's phenomenon (RP) is a transient, acral, vasospastic phenomenon that manifests with characteristic color changes. This vasospasm, classically triggered by cold temperatures, may also be driven by shifts in temperature, climate, or emotional state. Primary RP (PRP) is a common condition without severe sequelae. Secondary RP (SRP), which may be driven by vascular, autoimmune, hematologic, or endocrine etiologies, can result in digital ulceration, irreversible ischemia and necrosis, and secondary infection. This review delineates the clinical manifestations of both primary and secondary RP, as well as the current understanding of RP epidemiology and pathogenesis. Proper examination, including nailfold capillary microscopy, and laboratory workup for secondary causes of RP are also discussed. The traditional armamentarium of therapies used for RP, as well as newer medical and surgical options, is also summarized with particular regard to the clinical evidence for their efficacy.
