The safety and efficacy of additional chest tube placement in patients with prolonged air leaks after pulmonary resection: a propensity score-matched analysis.

This study evaluates the symptomatic management of prolonged pleural air leaks following pulmonary resection, assesses the efficacy and safety of chest tube placement, and introduces experiences with high-positioned chest tube insertion. We retrospectively reviewed 84 patients with prolonged pleural air leaks after lung surgery at Ningbo No.2 Hospital from January 2022 to December 2023. These patients were divided into a conservative treatment group (Group A, n = 64) and a chest tube placement group (Group B, n = 20). The propensity score matching method was applied to balance confounders between the two groups, resulting in 12 matched pairs. The study compared the time to chest tube removal, average hospital stays time, postoperative drainage volume, and facial visual analog pain score between the two groups. The average hospital stays and chest tube removal time of patients in group B were significantly lower than those of patients in group A (8.00 ± 1.12 vs. 9.75 ± 1.60 days, P = 0.003, 6.92 ± 1.08 vs. 8.58 ± 1.67 days, P = 0.005, respectively). However, the mean facial visual analog pain score in group B was higher than that in group A (1.58 ± 0.58 vs. 1.00 ± 0.01, P = 0.020). There were no significant differences between the two groups in terms of postoperative drainage volume. For patients with prolonged air leaks, additional chest tube placement postoperatively significantly reduces both hospitals stay duration and chest tube indwelling time compared to conservative treatment. This method may be a potential treatment measure for prolonged air leak in selected patients.

Features of diagnosis and treatment of a polytrauma victim with predominant closed chest trauma with lung and diaphragm rupture. Clinical case

The article describes a clinical case and presents clinical signs of traumatic rupture of the diaphragm and lung on the background of a wave‑like course of the postoperative period. Open diaphragmatic injuries are more common than closed ones. In this case, the closed chest and abdominal trauma was sustained as a result of a road traffic accident. The injury was combined and severe, with signs of traumatic shock. The location of the diaphragmatic injury was on the right side, which is less common. The severe condition of the patient with respiratory failure (respiratory rate over 30 per minute) was an indication for artificial lung ventilation, which made it impossible to take complaints and anamnesis. The individual spatial topography of the diaphragm depends on the size and location of the abdominal organs, body structure, and depends on the line of examination. The movement of internal organs into the pleural cavity indicates a diaphragmatic rupture, but in this case, the extrahepatic location of the diaphragmatic defect was covered by the liver, the lower lobe of the right lung, and adhesions, which led to the cover­up of the diaphragmatic defect. Increased abdominal size due to polytrauma and mechanical ventilation in case of closed chest and abdominal trauma; increased air discharge through pleural drainage during video laparoscopy or increased abdominal size during video thoracoscopy; clamping of the pleural drainage with a spiral computed tomography of the chest and abdominal organs allows detecting pneumoperitoneum and pneumothorax, which indicates the presence of a defect in the diaphragm and lung. The use of video thoracoscopy, video laparoscopy, and spiral computed tomography does not always provide complete information about the existing damage to the diaphragm, so dynamic observation with control radiological examinations is preferred.

Comparable bleeding and inflammation outcomes between heparin-coated and uncoated minimal invasive extracorporeal circuits in isolated coronary artery bypass surgery - A double-blinded randomized control trial.

Minimally invasive extracorporeal circulation has been shown to be non-inferior or even superior to conventional cardiopulmonary bypass circuits in isolated coronary artery bypass grafting, but there is little evidence whether the addition of a heparin-coated circuit can further reduce the inflammatory response and amount of bleeding in these patients. A single-center randomized control trial enrolled 49 adult patients scheduled to undergo isolated coronary artery bypass grafting with minimally invasive extracorporeal circulation (MiECC) between January 2015 and December 2018. Patients were randomized 1:1 to either the heparin-coated circuit group, or the uncoated (control) circuit group. The primary outcome was chest tube output 18h after weaning from MiECC, and secondary outcomes included inflammatory (TNF-α, IL-6, IL-8, IL-10) and complement (C3a, C4d, C5a, sC5b-9) biomarkers, platelet count and function (D2D, TAT, SDC1, PF4), number of transfused blood products, and 30-day survival. Patients were randomized to undergo myocardial revascularization using heparin-coated circuits (n = 25), and to the uncoated MiECC circuit (n = 24), with comparable baseline demographics. No significant difference was observed in chest tube output and for all secondary outcomes. IL-6 and IL-8 were increased from baseline at 18h after weaning (effect size 0.29 and 0.05, respectively) and sC5b-9 was lower (effect size 0.11) in the heparin-coated than in the uncoated MiECC, although not significantly different. Compared with an uncoated MiECC circuit, heparin-coated MiECC circuit was not associated with a reduction in postoperative bleeding, transfusion, inflammation, complement activation, and platelet biomarkers, following isolated coronary artery bypass grafting.

Air under pressure: a case report on tension pneumomediastinum arising from traumatic injury

Abstract Background Tension pneumomediastinum (TPM) is a rare but critical condition characterized by the accumulation of air in the mediastinum, leading to increased intrathoracic pressure and cardiovascular compromise. This case report is novel due to the rarity of TPM arising from blunt chest trauma and the necessity for emergent surgical intervention after initial conservative management failed. Case presentation A 63-year-old male presented with severe chest pain and dyspnea following a high-impact motor vehicle collision. Initial assessment revealed tachypnea, tachycardia, and hypotension, along with extensive subcutaneous emphysema over the chest and neck. Imaging confirmed pneumomediastinum and bilateral pneumothoraxes, consistent with TPM. Despite initial management with high-flow oxygen and bilateral chest tube insertion, the patient’s condition deteriorated, necessitating emergent mediastinal decompression via an anterior subxiphoid incision. This intervention resulted in immediate hemodynamic improvement. Conclusions This case underscores the importance of recognizing TPM in patients with chest trauma and highlights the need for prompt surgical intervention in cases of hemodynamic instability. Early and accurate diagnosis and timely surgical management are crucial for improving patient outcomes in TPM.

12227 The Battle Between Central And Nephrogenic Diabetes Insipidus

Abstract Disclosure: A.A. Luzuriaga Chavez: None. J.P. Hidalgo: None. A. Rao: None. N. Patel: None. Diabetes insipidus (DI) is a rare disorder characterized by excessive polyuria and polydipsia. The two main types include central diabetes insipidus (CDI), which results from antidiuretic hormone (ADH) deficiency and nephrogenic diabetes insipidus (NDI), defined by ADH resistance in the renal tubules. It can be challenging to distinguish between different types of DI in a critically ill patient. A 68-year-old female with a past medical history of hypertension, bipolar disorder came to the ER for complaints of chills and shortness of breath. She was transferred to the intensive care unit (ICU) for septic shock secondary to pneumonia and left pleural effusion. A chest tube was placed with improvement in her breathing and she was transferred out of the ICU. Four days later, the patient developed altered mental status, fevers and ICU was reconsulted due to concern for meningitis. A lumbar puncture was done with negative results but the brain MRI revealed ischemic sites involving both medial parietal cortices extending into both occipital poles, consistent with acute ischemia. Furthermore, the patient developed an increased urine output of 200ml per hour with a negative balance of 2.7L, increased sodium of 150, serum osmolality of 313 and urine osmolality of 196. The patient received desmopressin 1 mcg q 6 hrs with the persistence of hypernatremia. Upon further questioning, the patient had been on lithium therapy in the past for bipolar disorder. Amiloride 2.5mg BID was added to the treatment regimen. The patient’s hypernatremia and urine output improved and she was discharged on both amiloride and desmopressin to follow up for dose adjustments as needed. DI has a prevalence of 1 in 25000. Acquired CDI secondary to lesions in the hypophysis or hypothalamus highlights the major role of the central nervous system in regulating water homeostasis. This case report describes CDI developing after a stroke. Ischemia can cause hypoperfusion of osmoreceptors in the hypothalamus and posterior pituitary. Lithium can be frequently associated with NDI, usually seen in 20 to 40% of patients. Different mechanisms of action include lithium interference in renal collecting tubules by increasing cAMP in response to ADH and down-regulation of aquaporin-2 expression, which is accepted to be reversible with the cessation of the therapy. However, long-term treatment with lithium likely results in permanent NDI. Our patient had a history of lithium therapy which contributed to the development of symptoms of NDI and responded to a combination of desmopressin and amiloride. The successful therapy enforces the diagnosis of both a central and a peripheral pathology. Central and nephrogenic DI, despite stemming from distinct underlying causes, may concurrently manifest in critically ill patients. This case report emphasizes the need for physicians to evaluate for multiple causes of DI in a patient with water disturbances. Presentation: 6/1/2024

Real-world study on the application of enhanced recovery after surgery protocol in video-assisted thoracoscopic day surgery for pulmonary nodule resection

ObjectiveThis study aims to evaluate the real-world effectiveness of applying different levels of Enhanced Recovery After Surgery (ERAS) guidelines to video-assisted thoracic day surgery (VATS). The goal is to determine the optimal degree of ERAS protocols and management requirements to improve postoperative recovery outcomes.MethodsIt was designed as a single-centre, prospective pragmatic randomized controlled trial (PRCT), including patients who underwent VATS at the Day Surgery Center of West China Hospital, between January 2021 and November 2022. Patients were divided into Group A and Group B through convenience sampling to implement different levels of ERAS management protocols. Data collection included the baseline characteristics (gender, age, marital status, education level, BMI, PONV risk score, ASA classification), surgery-related indicators (type of surgery, pathological results, hospitalization costs, duration of surgery, intraoperative blood loss, intraoperative rehydration volume), postoperative recovery indicators (postoperative chest tube duration time, time to first postoperative ambulation and urination, postoperative complications, follow-up condition), pain-related indicators (pain threshold score, pain score at 6 h postoperatively, bedtime, and predischarge), psychological state indicators (anxiety level), Athens Insomnia Scale (AIS) scores, and social support scores. Propensity score matching (PSM) was utilized and statistical analyses were conducted using R version 4.4.1. Comparisons of categorical variables were performed using the χ² test, while comparisons of continuous variables were conducted using ANOVA or the Kruskal-Wallis rank-sum test. A significance level of α = 0.05 was set for statistical tests.ResultA total of 340 patients were included, with 187 in Group A and 153 in Group B. After propensity score matching (PSM), there were 142 patients in Group A and 105 in Group B, with no significant baseline differences. Group A had a significantly higher proportion of chest tube removals within 24 h postoperatively (P < 0.001) and earlier mobilization (P < 0.001). Despite a higher pain threshold in Group A (P = 0.016), their postoperative pain scores were not higher than those in Group B. Additionally, Group A had a lower incidence of postoperative complications.ConclusionThe more comprehensive ERAS protocol significantly improved postoperative recovery, confirming its value in day-case VATS and supporting its clinical adoption. However, the study has limitations; future research should focus on standardizing ERAS protocols and expanding their application to a broader patient population to validate these findings further.Trail RegistrationThis study underwent review by the Ethics Committee of West China Hospital of Sichuan University under No. 2020 (1001). It has been officially registered with the China Clinical Trial Registry, TRN: ChiCTR2100051372 and registration date is Sept. 22, 2021.

Real-world effectiveness and safety of handheld ultrasound in pleural procedures.

The use of ultrasound for pleural procedures is associated with a decreased risk of complications. Handheld ultrasounds allow for easier evaluation of the pleural space. Limited data exists for the use of such devices for pleural procedures. The primary objective of our study was to assess the effectiveness and safety of handheld ultrasound for pleural procedures. We performed a prospective observational study, including all consecutive patients who underwent pleural procedures using the handheld ultrasound between September 2021 and November 2023. A total of 332 pleural procedures were attempted with handheld ultrasound, of which 329 pleural procedures (99.1%) were successfully performed. The median volume of fluid drained was 500 (interquartile range: 300-800). Thoracentesis was performed in 127 patients (38.5%), tube thoracostomy in 179 patients (54.4%), and medical thoracoscopy in 23 patients (7.0%). Exudative pleural effusions were found in 264 patients (80.0%), of which 152 (46.2%) were determined to be due to infectious etiologies. A total of 4 (1.2%) patients had a complication due to the procedure. 2 patients (0.6%) had a pneumothorax, while 2 patients (0.6%) developed a hemothorax. A total of 101 patients had either low platelets (<50×109/L) or use of anti-platelet or anti-coagulant drugs. 128 patients (38.8%) were on positive pressure support during the pleural procedure. Our study shows that handheld ultrasounds are effective and safe for pleural procedures, including cases with septated pleural effusions and patients on anti-platelet or anti-coagulant drugs.

Clinical challenges and management of late presenting congenital diaphragmatic hernia mimicking tension pneumothorax in a child: a case report and review of literatures

BackgroundCongenital diaphragmatic hernia(CDH) is a rare congenital anomaly characterized by herniation of abdominal contents into thoracic cavity through a defect in diaphragm. While commonly diagnosed prenatally or in neonatal period, late-presenting CDH can occur and may mimic other thoracic emergencies such as tension pneumothorax, complicating diagnosis and management.Case presentationA two-year old male black child from Ethiopia presented to the emergency department with sudden onset of acute respiratory distress. Initial clinical assessment and chest radiography suggested a diagnosis of tension pneumothorax due to the presence of significant mediastinal shift and apparent pleural air. Despite insertion of chest tube, the child’s condition did not improve, raising suspicion of alternative diagnosis. Careful observation of initial chest x-ray and subsequent chest ultrasound revealed a left sided congenital diaphragmatic hernia with herniation of stomach and intestine into thoracic cavity compressing the left lung and causing mediastinal shift. After the diagnosis of CDH was confirmed, the child was stabilized and emergent surgical repair performed. Postoperative recovery was uneventful, and the child was discharged with no significant long-term complications.ConclusionThis case underscores the importance of considering CDH in the differential diagnosis of acute respiratory distress in a child. It highlights the diagnostic challenges and potential risks of emergency interventions based on initial misdiagnosis. Even if x -ray looks like typical of tension pneumothorax, it showed giant cystic air filled structure pushing the mediastinal structure to contralateral side with loss of left diaphragmatic outline which raised suspicion of congenital cystic lung mass or congenital diaphragmatic hernia. Advanced imaging and high index of suspicion are crucial for accurate diagnosis and timely management, ultimately improving patient outcomes. Consideration of alternative diagnosis when our initial intervention with insertion of chest tube fail to provide symptom improvement in suspected pneumothorax should raise suspicion of congenital diaphragmatic hernia like in our case.

Re-Expansion Pulmonary Edema Post-Pneumothorax

Vacuum pulmonary edema is a rare yet potentially serious complication, associated with a mortality rate of 15 to 20%. It typically arises as an uncommon consequence of draining a pneumothorax or pleural effusion, presenting with symptoms such as cough, chest pain, and hypoxemia. In severe cases, it can lead to shock and even death, with symptoms generally appearing within 24 hours following thoracentesis. Management is primarily supportive, involving treatments that range from oxygen supplementation to both non-invasive and invasive ventilation techniques. Preventive measures include using low negative pressure (&lt; −20 cm H2O) during suction in thoracentesis and avoiding excessive pleural fluid drainage if the patient experiences chest discomfort. We present a case of a patient who developed vacuum pulmonary edema subsequent to the drainage of a pneumothorax.

The efficacy of loco-regional ropivacaine analgesia via intercostal catheters after lung resection: a randomized, double-blind, placebo-controlled, superiority study.

Postoperative pain remains a burden for patients after minimally invasive anatomic lung resection. Current guidelines recommend the intraoperative placement of intercostal catheters to promote faster recovery. This trial aimed to determine the analgesic efficacy of continuous loco-regional ropivacaine application via intercostal catheter and establish this method as a possible standard of care. Between December 2021 and October 2023, patients were randomly assigned to receive ropivacaine 0.2% or a placebo through an intercostal catheter with a flow rate of 6-8 ml/h for 72 h after surgery. Patients were undergoing anatomic VATS lung resection under general anaesthesia for confirmed or suspected stage I lung cancer (UICC, 8th edition). The sample size was calculated to assess a difference in numerical rating scale associated with pain reduction of 1.5 points. Fourteen patients were included in the ropivacaine group, whereas the placebo group comprised 18 participants. Patient characteristics and preoperative pain scores were similar in both groups. There was no statistically significant difference in postoperative pain scores and morphine consumption between the 2 groups. The mean numerical rating scale when coughing during the first 24 h postoperatively was 4.9 (SD: 2.2) in the ropivacaine group and 4.3 (SD: 2.4); P = 0.47 in the placebo group. We were unable to determine any effect of administered ropivacaine on the postoperative pulmonary function (FEV1, PEF). Our preliminary results suggest that continuous loco-regional ropivacaine administration via surgically placed intercostal catheter has no positive effect on postoperative pain scores or morphine requirements.

A novel case of simultaneous tracheal stenting and endobronchial valve (EBV) deployment for tracheal stenosis and persistent air leak guided by an endobronchial collateral ventilation assessment system and digital chest drain in malignant esophageal carcinoma.

Persistent air leak may complicate malignant disease of the thorax, causing significant morbidity and mortality. A 51-year-old male with a 30-pack-year history of smoking was diagnosed with metastatic esophageal carcinoma with invasion into the right upper lobe of the lung. He developed a large right hydropneumothorax complicated by empyema leading to persistent air leak despite the insertion of two chest drains. Computed Tomography imaging with 3-dimensional reconstruction showed severe tracheal compression from the enlarging esophageal tumour as well as bronchopleural fistulas in the right upper lobe. Rigid bronchoscopy with metallic tracheal stenting was performed. This was followed by localization and quantification of air leak with an endobronchial collateral ventilation assessment system and a digital chest drain to guide endobronchial valve placement, in a single operative procedure. This novel combination of interventional bronchoscopy techniques enabled successful transition to an ambulatory chest drain and subsequent hospital discharge.

A retrospective analysis of simultaneous bilateral uniportal thoracoscopic surgeries for multiple primary bilateral pulmonary nodules

BackgroundThere are no standard treatment options for bilateral multiple pulmonary nodules requiring resection. This study aimed to summarize the experience of simultaneous bilateral uniportal video-assisted thoracoscopic surgery for the treatment of bilateral multiple primary pulmonary nodules.MethodsThe clinical data of 65 cases of simultaneous bilateral uniportal thoracoscopic surgery for bilateral multiple primary pulmonary nodules treated were retrospectively analyzed. These cases were treated within The Ninth Medical Center of PLA General Hospital between January 2018 and November 2020. Parameters related to the surgery, perioperative aspects, surgical techniques, pathology results, and postoperative complications were examined.ResultsAll surgeries were conducted through uniportal video-assisted thoracoscopic surgery, with no instances of intraoperative conversion to thoracotomy. Fifty-three patients further underwent CT-guided Hookwire localization for the localization of pulmonary nodules. A total of 189 nodules were resected using multiple surgical procedures, with a malignancy rate of 86.2%. The average operation time was 226 ± 77.4 min, the average thoracic drainage duration was 3.1 ± 1.5 days, the average 24 h pleural drainage was 385.9 ± 157.4 mL, the average postoperative hospital stay was 8.6 ± 2.4 days, and the average blood loss was 77.2 ± 33.8 mL. Post-surgery, all patients were transferred to the ward safely within 12 h. 15.38% of patients have prolonged drainage time, and 12.31% of patients experience complications such as lung infection, arrhythmia, and venous thrombosis.ConclusionThe selected cases undergoing simultaneous bilateral uniportal video-assisted thoracoscopic surgery for the management of bilateral multiple primary pulmonary nodules demonstrated favorable outcomes. Our observations indicate the safety and feasibility of this procedure, providing an individualized and precise treatment approach for affected patients.

Recommended recumbency to avoid insertional complications during small-bore wire-guided thoracostomy tube placement in cats—a cadaver study

BackgroundSmall-bore wire-guided thoracostomy tubes (SBWGTT) are commonly used in cats to manage pleural disease and generally have a low complication rate. Our study aimed to explore the correlation between recumbency of cats, placement method, and the occurrence of insertional complications to identify risk factors during SBWGTT placement.In this experimental cadaveric study, SBWGTT placement using a modified Seldinger technique was conducted in 24 feline cadavers. Cats, euthanized for reasons unrelated to the study, were randomly assigned to pleural effusion (EFF; n = 12) and pneumothorax (PNEU; n = 12) groups. Each cadaver was intubated and ventilated with a peak inspiratory pressure (PIP) of 10 mmHg, and sterile saline or air was instilled into the thorax over a 5 mm thoracoscopic trocar in the fourth intercostal space (ICS). Instillation was stopped when the lateral thoracic wall to lung distance (TWLD) reached 10 to 12 mm, measured with ultrasound in the favorable position. Sternal recumbency was the favorable position for the EFF group, and lateral recumbency for the PNEU group. Following the placement of the first SBWGTT in each group, the cadavers were positioned unfavorably (lateral recumbency for EFF group, sternal recumbency for PNEU group), and a second drain was introduced contralaterally. A bilateral 8th ICS thoracotomy was then performed to visually assess intrathoracic structures and drain integrity.A binary logistic regression mixed model was conducted to determine interaction between the induced condition and body position.ResultsA total of 48 SBWGTTs were placed, with complications observed in 33.3% (8/24) of cases. Five of these were major complications consisting of lung lacerations. Complications were more common in the unfavorable position, accounting for 75% of cases, although this result was not statistically significant. The odds of complication rates were > 70% in the unfavorable position and decreased with an increase in TWLD (< 30%).ConclusionComplications associated with SBWGTT placement are influenced by recumbency, although the data did not reach statistical significance. Placing cats in lateral recumbency for pneumothorax treatment and sternal recumbency for pleural effusion treatment may reduce insertional complications.

Assessment of intercostal nerve block analgesia and local anesthetic infiltration for thoracoscopic pulmonary bullae resection: a comparative study

ObjectiveThe purpose of this study was to compare the analgesic effects of intercostal nerve block (ICNB) and local anesthetic infiltration (LAI) on postoperative pain and recovery following thoracoscopic resection of pulmonary bullae.MethodsA total of 160 patients undergoing thoracoscopic pulmonary bullae resection were randomly assigned to receive either ICNB (n = 80) or LAI (n = 80). An experienced anesthesiologist administered ultrasound guided ICNB at the T4 and T7 levels with 5 mL of 0.375% ropivacaine hydrochloride for the ICNB group. Instead, the LAI group received 10 mL of the same concentration of ropivacaine hydrochloride at the same concentration used for ICNB for infiltration anesthesia at the incision sites. Out of the initial cohort, 146 patients completed the study (ICNB group, n = 71; LAI group, n = 75). The collected data included preoperative clinical characteristics, visual analog scale (VAS) scores for pain at various time points post-surgery (6, 12, 24, 48, and 72 h). Additionally, the Quality of Recovery-15 (QoR-15) questionnaire was administered 24 h after surgery, and sleep quality was evaluated using the Pittsburgh Sleep Quality Index (PSQI).ResultsNo significant differences were found in drainage volume, use of additional analgesics, duration of chest tube placement, or hospital stay between the two groups. However, the ICNB group had significantly lower VAS scores and QoR-15 scores 24 h postoperatively (p < 0.05), indicating better pain management and recovery. The ICNB group also reported better sleep quality, as reflected by lower PSQI scores.ConclusionICNB provides superior analgesia compared to LAI after thoracoscopic resection of pulmonary bullae, significantly improving postoperative recovery.

Perioperative Outcomes Related to Thoracic and Lumbar Spine Exposure During Vertebral Body Tethering for Adolescent Idiopathic Scoliosis: A Large, Single-Institution Retrospective Review

BackgroundVertebral body tethering (VBT) is a novel non-fusion technique for the management of scoliosis. Despite growing popularity, data concerning complications and thoracic surgery-related outcomes are lacking. MethodsA single-institution retrospective review was conducted of patients who underwent VBT with video-assisted thoracic surgical exposure from 1/1/2015-3/1/2022. Data obtained included demographics, comorbidities, hospital course, and outcomes. Results106 patients (81% female) were identified with a mean age at surgery of 12.7±1.5 (range 9-16). Most patients underwent single curve tethering (n=93, 87.7%) with a mean number of vertebral bodies tethered of 8.0 (range 5-13). The mean operative time was 236±96 minutes (range 129-661) minutes with an estimated blood loss of 165±143 mL (range 20-750) and no patients required allogeneic blood transfusion. The extent of tethering was significantly associated with increased operative time, fluids received, and chest tube output. Excluding instrument-related complications, the complication rate was 13.2%, mostly occurring within the first 30 days after surgery and pleural effusion being the most common event. Two patients experienced a postoperative hemothorax requiring reoperation. No patients experienced sequelae of spinal cord ischemia secondary to the division of intercostal and/or lumbar vessels during surgical exposure and no deaths occurred. ConclusionVBT is a seemingly safe alternative to spinal fusion in skeletally immature adolescents, however, there are notable complications of this procedure related to thoracic exposure. Our experience indicates clinically significant pulmonary complications are uncommon and the extent of vertebral body exposure/tethering was strongly associated with operative duration, fluids, and chest tube output. Levels of EvidenceThis original article represents a treatment study of Level IV evidence.

Combined antegrade and retrograde dilation (CARD) for management of complete esophageal obstruction: Multicenter case series.

Background and study aims Complete esophageal obstruction (CEO) is a rare complication of radiation therapy for esophageal or head and neck cancers and can be challenging to manage endoscopically. A rendezvous approach by combined anterograde and retrograde endoscopic dilation (CARD) can be used to re-establish luminal integrity in such cases. Our study aimed to review our experience with patients with CEOs managed by CARD. Patients and methods Six patients who had CARD for CEO were reviewed. The primary outcomes were immediate technical and clinical success of CARD. Secondary outcomes were adverse events (AEs) associated with the procedure and continued dependency on the percutaneous endoscopic gastrostomy (PEG)-or jejunostomy tube. Results The mean age was 59 years (range 38-83). Five patients had CEO secondary to neoadjuvant chemoradiotherapy for esophageal cancer, and one patient had complete obstruction secondary to neck trauma. CARD was technically successful in five patients (86%). Two patients had AEs. One had pneumomediastinum requiring no intervention, while the other had bilateral pneumothorax requiring chest tube placement. The median follow-up duration of repeated dilations to maintain liminal patency was 20 months. Four patients had improvement in dysphagia, tolerating oral intake, and mouth secretions after the procedure, with a mean functional oral intake scale (FOIS) score > 3 and an overall success rate of 83%. Conclusions The CARD approach to re-establish esophageal luminal patency in CEO is a safer alternative to high-risk blind antegrade dilation or an invasive surgical approach. It is usually technically feasible with improved swallowing ability in most patients.

The Impact of a Residual Atrial Communication in Patients Undergoing Complete Repair for Tetralogy of Fallot: A Propensity Score Matched Analysis

Surgeons may leave a residual atrial-level communication during complete repair of Tetralogy of Fallot (TOF) in anticipation of restrictive right ventricle physiology or as routine practice. We investigated the impact of closing the interatrial communication at the time of definitive TOF repair. We retrospectively reviewed TOF patients who underwent definitive repair at <12 months of age between June 2000 and January 2023. Propensity score matching identified 82 patients with a patent interatrial communication and 50 with no interatrial communication on postoperative echocardiography (as-treated analysis). The primary endpoint was maximum vasoactive-inotropic score (VIS) as a surrogate for low cardiac output syndrome. A total of 132 patients (median age: 3.5[IQR,1.8-5.8] months) were matched. There was no difference in maximum VIS (patent interatrial communication: 5.0[IQR, 4.8-9.0] vs. no interatrial communication: 6.0[IQR, 5.0-8.0], P=0.78). Additionally, duration of inotrope therapy (3.0[IQR, 2.0-4.0] vs 3.0[IQR, 1.3-4.0] days, P=0.57), peak lactate (2.2[IQR, 1.9-3.0] vs. 2.3[IQR, 1.9-3.2] mmol/L, P=0.58), time to lactate clearance (0.2[IQR, 0.0-0.3] vs. 0.1[IQR, 0.0-0.3] days, P=0.57), chest tube duration (4.0[IQR,3.0-6.0] vs 4.0[IQR, 3.0-5.0] days, P=0.23), and length of intensive care stay (5.0[IQR, 3.0-7.0] vs. 5.0[IQR, 3.0-7.0] days, P=0.71) were similar. Median follow-up was 5.5[IQR, 2.7-9.9] years. Among patients with a residual communication, patency rates were 93.6% and 53.7% at discharge and latest follow-up, respectively, with most having bidirectional shunting across the defect. Closure of the atrial-level communication during complete TOF repair does not significantly impact the immediate postoperative course or mid-term outcomes. Further investigation is warranted to better understand how patency influences long-term outcomes.

Dedicated Chest Wall Injury Program quality review: How to create and incorporate a quality and safety program for surgical stabilization of rib fractures.

Adoption of surgical stabilization of rib fractures (SSRF) in chest trauma necessitates outcomes reviews and process improvement (PI). As volume and complexity increase, such vigilance is imperative. Over 10 years, our center has developed a dedicated PI program based on our trauma PI program. Here, we outline the components of this program, aiming to share best practices and potentially improve SSRF patient outcomes. Over 10 years, our dedicated SSRF PI process has evolved to include bimonthly reviews on case and quality metrics. In 2022, all patients at our single high-volume Level 1 trauma center with flail chest segments were identified, and a PI chart review was conducted. Data collected included management approach (operative vs. nonoperative), postoperative complications, mortality, patient demographics, trauma specific variables (Injury Severity Score, etc.), and rib fracture details. Operative data collected included number of ribs plated, system used, and complication rates for each surgeon and plating system used. Of 82 patients identified, 88% underwent SSRF. Among these, 49% experienced one or more postoperative complications, not all directly related to SSRF procedures. Mortality rate for SSRF patients was 15%, predominantly in those with Injury Severity Score of >25 and mean age of 58 years. Patients who had trauma activations and required emergency department chest tube placement had higher complications. The mean number of ribs stabilized was four. Complications occurred more frequently with posterior fractures. Outcomes were collated and analyzed at SSRF Outcomes Committee. The utilization of SSRF underscores the need for a rigorous quality review process to enhance patient safety and SSRF-specific outcomes. Our program developed over time from and was implemented in fashion similar to the trauma PI processes. The resulting quality initiative has fostered center-specific PI projects and programmatic advancements. Economic and Value-Base Evaluations; Level IV.
