RESUMO
INTRODUCTION: Spontaneous pneumothorax is a common thoracic surgical problem. To prevent recurrence, surgical options include blebectomy, mechanical or chemical pleurodesis, pleurectomy, or a combination of these operations. Pleurectomy is associated with lower recurrence rates but may be technically challenging via video-assisted thoracoscopic surgery. We report the first series of robotic-assisted pleurectomy (RAP) for spontaneous pneumothorax. METHODS: A retrospective, single-center analysis was conducted on consecutive patients undergoing RAP for spontaneous pneumothorax from 2017 to 2023. Patients with prior surgery on the same side for pneumothorax were excluded. Demographics, comorbidities, functional status, intraoperative and perioperative variables were collected. 30-d readmission, 30-d mortality, and recurrence were recorded. RESULTS: Thirty-six patients underwent RAP during the study period with a median follow-up of 36 mo. Patients had a median age of 41.5 (interquartile range [IQR] 21.5-68) y and were mostly male (80.6%) and past smokers (44.4%) with 66.6% having a primary spontaneous pneumothorax. The median time to chest tube removal was 3 d (IQR 2-3) and the median length of stay was two days (IQR 2-4). Complications occurred in seven patients with the majority (85.7%) having a grade 2 Clavien-Dindo classification score. There was no 30-d mortality or recurrence. CONCLUSIONS: Robotic-assisted pleurectomy for spontaneous pneumothorax is a safe and effective operation that can be used to prevent future recurrence.

The activity of cullin-RING type ubiquitination E3 ligases is regulated by neddylation, a process analogous to ubiquitination that culminates in covalent attachment of the ubiquitin-like protein Nedd8 to cullins. As a component of the E3 for neddylation, SCCRO/DCUN1D1 plays a key regulatory role in neddylation and, consequently, cullin-RING ligase activity. The essential contribution of SCCRO to neddylation is to promote nuclear translocation of the cullin-ROC1 complex. The presence of a myristoyl sequence in SCCRO3, one of four SCCRO paralogues present in humans that localizes to the membrane, raises questions about its function in neddylation. We found that although SCCRO3 binds to CAND1, cullins, and ROC1, it does not efficiently bind to Ubc12, promote cullin neddylation, or conform to the reaction processivity paradigms, suggesting that SCCRO3 does not have E3 activity. Expression of SCCRO3 inhibits SCCRO-promoted neddylation by sequestering cullins to the membrane, thereby blocking its nuclear translocation. Moreover, SCCRO3 inhibits SCCRO transforming activity. The inhibitory effects of SCCRO3 on SCCRO-promoted neddylation and transformation require both an intact myristoyl sequence and PONY domain, confirming that membrane localization and binding to cullins are required for in vivo functions. Taken together, our findings suggest that SCCRO3 functions as a tumor suppressor by antagonizing the neddylation activity of SCCRO.

Minimally invasive thoracic surgery has advanced the treatment of lung cancer since its introduction in the 1990s. Video-assisted thoracoscopic surgery (VATS) and robotic-assisted thoracic surgery (RATS) offer the advantage of smaller incisions without compromising patient outcomes. These techniques have been shown to be safe and effective in standard pulmonary resections (lobectomy and sub-lobar resection) and in complex pulmonary resections (sleeve resection and pneumonectomy). Furthermore, several studies show these techniques enhance patient outcomes from early recovery to improved quality of life (QoL) and excellent oncologic results. The rise of RATS has yielded further operative benefits compared to thoracoscopic surgery. The wristed instruments, neutralization of tremor, dexterity, and magnification allow for more precise and delicate dissection of tissues and vessels. This review summarizes of the advancements in minimally invasive thoracic surgery and the positive impact on patient outcomes.
RESUMO
BACKGROUND: Segmentectomy is increasingly performed for non-small cell lung cancer. However, comparative outcomes data among open, robotic-assisted, and video-assisted thoracoscopic approaches are limited. METHODS: A retrospective cohort study of non-small cell lung cancer segmentectomy cases (2013-2021) from the Society of Thoracic Surgeons General Thoracic Surgery Database was performed. Baseline characteristics were balanced using inverse probability of treatment weighting and compared by operative approach. Volume trends, outcomes, and nodal upstaging were assessed. RESULTS: Of 9927 patients who underwent segmentectomy, 84.8% underwent minimally invasive surgery, with robotic-assisted thoracoscopic surgery becoming the most common approach in 2019. Open segmentectomy is more likely to be performed at low-volume centers (P < .0001), whereas robotic-assisted thoracoscopic surgery is more likely to be performed at high-volume centers (P < .0001). Video-assisted thoracoscopic surgery had a higher open conversion rate than robotic-assisted thoracoscopic surgery (odds ratio, 11.8; CI, 7.01-21.6; P < .001). Minimally invasive surgery had less 30-day morbidity compared with open segmentectomy (video-assisted thoracoscopic surgery odds ratio, 0.71; 95% CI, 0.55-0.94; P = .013; robotic-assisted thoracoscopic surgery odds ratio, 0.59; CI, 0.43-0.81; P = .001). The number of nodes and stations harvested were highest for robotic-assisted thoracoscopic surgery; however, N1 upstaging was more likely in open compared with robotic-assisted thoracoscopic surgery (odds ratio, 0.63; CI, 0.45-0.89; P < .007) and video-assisted thoracoscopic surgery (odds ratio, 0.61; CI, 0.46-0.83; P = .001). CONCLUSIONS: Segmentectomy volume has increased considerably, with robotic-assisted thoracoscopic surgery becoming the most common approach. Minimally invasive surgery has less major morbidity compared with open segmentectomy, with no difference between video-assisted thoracoscopic surgery and robotic-assisted thoracoscopic surgery. However, risk of open conversion is higher with video-assisted thoracoscopic surgery. Robotic-assisted thoracoscopic surgery had increased nodal harvest, whereas hilar nodal upstaging was highest with thoracotomy. This study reveals significant differences in outcomes exist between segmentectomy operative approach; the impact of approach on survival merits further investigation.
RESUMO
BACKGROUND: The aim of this study was to determine the predictive value of the preoperative three-dimensional reconstructed volume (3D volumetry) for outcomes of laparoscopic splenectomy. The impact of splenomegaly on the feasibility of laparoscopic splenectomy is still debated. We hypothesized that splenic volumetry may accurately estimate splenic volume preoperatively and be used by surgeons to select patients for laparoscopic splenectomy. METHODS: We performed a retrospective review of 88 patients seen at a tertiary referral center undergoing laparoscopic or open splenectomy between 2001 and 2010. Patients included in the study underwent elective splenectomy without associated procedures and had preoperative imaging available at our institution. We evaluated clinical, demographic characteristics and perioperative imaging as predictors of outcome. Study endpoints included conversion to open splenectomy, operating time, estimated blood loss (EBL), length of stay (LOS), postoperative complications, and mortality. RESULTS: In all, 53 procedures were started laparoscopically. Among them, 7 (13.2 %) were converted to open splenectomy and 7 (13.2 %) to hand-assisted laparoscopic splenectomy. The conversion group was matched with 35 patients who underwent open splenectomy to determine differences in outcomes between these groups. There were no conversions in spleens measuring <1100 cc, whereas spleens of 1100 to 2700 cc had a conversion rate of 41 %. Spleen volume >2700 cc was associated with an 87.5 % conversion rate. Spleen 3D volumetry >2700 cc was the only independent predictor of surgical conversion on multivariate analysis (odds ratio 38.0, confidence interval 4.02-358.75, p = 0.001). Patients who underwent open splenectomy had shorter operating times (160.3 vs. 253.0 min, p = 0.001) than those converted from laparoscopic to open splenectomy. CONCLUSIONS: A 3D reconstructed splenic volume of >2700 cc is a predictor of conversion from laparoscopic to open splenectomy. For spleens measuring <2700 cc, laparoscopic splenectomy may be performed by experienced surgeons with low to moderate rates of conversion. For spleens with a 3D reconstructed volume >2700 cc, laparoscopic splenectomy is associated with high rates of conversion to open surgery.

OBJECTIVES: Plavix (clopidogrel) is a potent antiplatelet agent used to prevent thrombosis in a variety of clinical settings. The perioperative management of thoracic surgery patients who are on clopidogrel at the time of surgery is not well defined. We conducted this review to examine the perioperative management and outcomes of patients undergoing general thoracic surgical procedures. METHODS: From January 2005 to January 2010, 165 patients on clopidogrel underwent 182 operative procedures. Three management strategies were identified: Group I: clopidogrel continued through surgery (n = 17), Group II: clopidogrel discontinued with a bridging agent (n = 44) and Group III clopidogrel discontinued without a bridging agent (n = 121). Propensity score matched cohorts (17 clopidogrel continued; 34 clopidogrel discontinued) were constructed based on age, clopidogrel indication, American Society of Anesthesiology status, and procedure and used to compare the impact of clopidogrel management on postoperative bleeding and cardiovascular morbidity. RESULTS: Unmatched analysis revealed a significantly higher rate of transfusion in the group of patients who continued on clopidogrel throughout the perioperative period, compared with patients who had clopidogrel discontinued. Although there were more cardiovascular events in Groups II and III, there were no significant differences between groups in postoperative mortality, myocardial infarction, stroke, or reoperation for bleeding. In propensity matched patients only the rate of postoperative transfusions was significantly higher in patients continued on clopidogrel compared with patients whose clopidogrel was discontinued (35.3 vs. 2.9%), p < 0.004. CONCLUSIONS: In selected patients, some thoracic surgical procedures can be performed safely on clopidogrel but are associated with higher rates of postoperative transfusion.

The robotic platform can be viewed as an advanced thoracoscopic instrument and can be utilized for any pathology amenable to thoracoscopic surgery. This ultimately comes down to surgeon comfort, but many have demonstrated the robotic approach to be useful in benign and malignant mediastinal disease in all compartments with at least equivalent-if not superior-outcomes compared to sternotomy for many metrics. There are various robotic approaches to the same compartments (such as with thymectomy), and no one robotic approach has proven superior to another. Here we describe our robotic approach to common mediastinal pathology.

BACKGROUND: Prolonged air leak (PAL) (>5 days) after robotic-assisted pulmonary lobectomy is a significant complication. This study aimed to determine patient- and surgeon-related factors that can predict PAL after robotic lobectomy for lung cancer. METHODS: This study was a retrospective review of a single-center experience of robotic-assisted lobectomy for lung cancer. Perioperative variables, including surgeon case experience, patient demographics, diffusion capacity of lung for carbon monoxide, forced expiratory volume in 1 second, body mass index, and smoking status were evaluated. RESULTS: A total of 305 robotic-assisted lobectomies performed by 4 surgeons met inclusion criteria from June 2016 to February 2019. The 30-day postoperative mortality was 1.2%. PAL developed in 27 of 305 (8.8%) patients. Surgeons' robotic experience was grouped by 10-case increments. When adjusted for age and sex, the odds for PAL decreased by 15% for every 10 robotic lobectomies the surgeons performed (odds ratio [OR], 0.85; 95% CI, 0.74-0.99; P = .0384). Logistic regression models showed a linear transition curve at the 50th case. Female sex (OR, 2.62; 95% CI, 1.03-6.69; P = .0314) and younger age (OR, 0.61; 95% CI, 0.41-0.91; P = .0184) were statistically significant risk factors for PAL. Cumulative sum analysis similarly showed a strong association between experience and PAL. Preoperative diffusing capacity of lung for carbon monoxide, forced expiratory volume in 1 second, body mass index, and smoking status were not statistically significant predictive factors. CONCLUSIONS: These results show that surgeon robotic case experience is associated with the rate of postoperative PAL: as the number of robotic lobectomies increases, the rate of PAL significantly decreases. It is imperative to emphasize that a learning curve exists for this approach that directly affects patient outcomes.

BACKGROUND: Conversion to thoracotomy during minimally invasive lobectomy for lung cancer is occasionally necessary. Differences between video-assisted thoracoscopic surgery (VATS) and robotic-assisted thoracoscopic surgery (RATS) lobectomy conversion have not been described. METHODS: We queried The Society of Thoracic Surgeons General Thoracic Surgery Database from January 1, 2015 to December 31, 2018. Patients with prior thoracic operations and metastatic disease were excluded. Univariable comparisons with χ2 and Kruskal-Wallis tests and multivariable logistic regression modeling were performed. RESULTS: There were 27,695 minimally invasive lobectomies from 269 centers. Conversion to thoracotomy occurred in 11.0% of VATS and 6.0% of RATS (P < .001). Conversion was associated with increased mortality (P < .001), major complications (P < .001), and intraoperative (P < .001) and postoperative (P < .001) blood transfusions. Conversion from RATS occurred emergently (P < .001) and for vascular injury (P < .001) more frequently than from VATS, but there was no difference in overall major complications or mortality. Mortality after conversion was 3.1% for RATS and 2.2% for VATS (P = .24). Clinical cancer stage II or III (P < .001), preoperative chemotherapy (P = .003), forced expiratory volume in 1 second (P = .006), body mass index (P < .001), and left-sided resection (P = .0002) independently predicted VATS conversion. For RATS clinical stage III (P = .037), left-sided resection (P = .041), and forced expiratory volume in 1 second (P = .002) predicted conversion. Lower volume centers had increased rates of conversion (P < .001) in both groups. CONCLUSIONS: Conversion from minimally invasive to open lobectomy is associated with increased morbidity and mortality. Conversion occurs more frequently during VATS compared with RATS, albeit less often emergently, and with similar rates of overall mortality and major complications. Predictors, urgency, and reasons for conversion differ between RATS and VATS lobectomy and may assist in patient selection.

OBJECTIVES: Approximately 15% of stage I lung adenocarcinomas will recur despite adequate surgical therapy. Adjuvant therapy may benefit specific high-risk subsets; however, it is unclear which patients are sufficiently predisposed to recurrence to warrant intensified therapy. MATERIALS AND METHODS: 517 AJCC 8th edition stage I/0 lung adenocarcinomas ≤ 4 cm total size were graded (WHO-2015 and WHO-2021) and compared to stage subgroupings using 7-year recurrence free (RFS), disease specific (DSS), and overall survival (OS). Low malignant potential (LMP) adenocarcinoma was assigned as previously defined. Univariate/multivariate analysis was performed to assess risk factors associated with aggressive behavior. RESULTS: Vascular invasion was the most significant histologic feature on multivariate analysis for both RFS (HR = 4.68, p < 0.001) and DSS (HR = 3.67, p = 0.001) and nearly reached significance for OS (HR = 1.47, p = 0.060). Angioinvasive adenocarcinomas comprised 26 % of the cohort and exhibited a 7-year 64 % RFS, 73 % DSS, and 50 % OS; in contrast to 20 % WHO-2015-G3 (7-year 71 % RFS, 79 % DSS, & 54 % OS), 44 % WHO-2021-G3 (7-year 79 % RFS, 85 % DSS, & 56 % OS), and 21 % stage IB (7-year 72 % RFS, 79 % DSS, and 50 % OS) adenocarcinomas. The majority (>50 %) of overall mortality was disease specific for angioinvasive adenocarcinoma whereas ≤25 % of overall mortality was disease specific for the remaining tumors. Angioinvasive adenocarcinomas were proportionally more common among those still smoking at diagnosis (49 %), male sex (49 %), and black race (16 %) than other subtypes. CONCLUSION: Patients with AJCC 8th ed. stage I angioinvasive lung adenocarcinomas are at high-risk of cancer-specific mortality and should be considered for clinical trials evaluating benefit of adjuvant therapy.

CONTEXT: Heterotopic pancreatic adenocarcinoma is a rare finding at laparotomy. Herein we present the case of a patient with malignant transformation of a heterotopic pancreas located in the fourth portion of the duodenum. CASE REPORT: A 79-year-old woman was admitted to the surgery service with complaints of early satiety and abdominal fullness progressively worsening over the previous two years. A computed tomography scan of the abdomen and an upper endoscopy revealed an obstructing mass in the fourth portion of the duodenum, biopsies were negative for carcinoma. A segmentectomy of the third and fourth portions of the duodenum was performed. Post-operative histology revealed malignant transformation of a heterotopic pancreas. The patient had an unremarkable postoperative recovery and was discharged home. CONCLUSION: In evaluation of patients with distal duodenal masses, we report that heterotopic pancreatic neoplasms should be considered in the differential diagnosis.

OBJECTIVE: Lung cancer screening with low-dose chest computed tomography improves survival. However, concerns about overdiagnosis and unnecessary interventions persist. We reviewed our lung cancer screening program to determine the rate of surgery and invasive procedures for nonmalignant disease. METHODS: We reviewed all patients undergoing lung cancer screening from January 2012 to June 2017 with follow-up through January 2019. Patients with suspicious findings (Lung CT Screening Reporting and Data System 4) were referred for further evaluation. RESULTS: Of 3280 patients screened, 345 (10.5%) had Lung CT Screening Reporting and Data System 4 findings. A total of 311 patients had complete follow-up, of whom 93 (29.9%) were diagnosed with lung cancer. Eighty-three patients underwent lung surgery (2.5% of screened patients). Forty patients underwent lobectomy (48.2%), 3 patients (3.6%) underwent bilobectomy, and 40 patients (48.2%) underwent sublobar resection. Fourteen patients underwent surgery for benign disease (0.43% of screened patients). Fifty-four patients, 5 with benign disease, had at least 1 invasive diagnostic procedure but never underwent surgery. The incidence of any invasive intervention for nonmalignant disease was 0.95% (31/3280 patients). There were no postprocedural deaths within 60 days. Twenty-five patients (0.76%) underwent stereotactic body radiation therapy; 19 patients (76%) had presumed lung cancer without pretreatment pathologic confirmation. CONCLUSIONS: Surgical resection for benign disease occurred in 0.43% of patients undergoing lung cancer screening. The combined incidence of any invasive diagnostic or therapeutic intervention, including surgical resection, for benign disease was only 0.95%. Periprocedural complications were rare. These results indicate that concern over unnecessary interventions is overstated and should not hinder adoption of lung cancer screening. A multidisciplinary team approach, including thoracic surgeons, is critical to maintain an appropriate rate of interventions in lung cancer screening.

Lung cancer screening has improved mortality among high-risk smokers but has coincidentally detected a fraction of nonprogressive adenocarcinoma historically classified as bronchoalveolar carcinoma (BAC). In the National Lung Screening Trial (NLST) the majority of BAC-comprising 29% of computed tomography-detected stage I lung adenocarcinoma-were considered overdiagnosis after extended follow-up comparison with the control arm. In the current classification, adenocarcinoma in situ and minimally invasive adenocarcinoma have replaced BAC but together comprise only â¼5% of stage I lung adenocarcinoma. Lepidic and subsets of papillary and acinar adenocarcinoma also infrequently recur. We, therefore, propose criteria for low malignant potential (LMP) adenocarcinoma among nonmucinous adenocarcinoma measuring ≤3 cm in total, exhibiting ≥15% lepidic growth, and lacking nonpredominant high-grade patterns (≥10% cribriform, ≥5% micropapillary, ≥5% solid), >1 mitosis per 2 mm2, angiolymphatic or visceral pleural invasion, spread through air spaces or necrosis. We tested these criteria in a multi-institutional cohort of 328 invasive stage I (eighth edition) and in situ adenocarcinomas and observed 16% LMP and 7% adenocarcinoma in situ/minimally invasive adenocarcinoma which together (23%) approximated the frequency of overdiagnosed stage I BAC in the NLST. The LMP group had 100% disease-specific survival. The proposed LMP criteria, incorporating multiple histologic parameters, may be a clinically useful "low-grade" prognostic group. Validation of these criteria in additional retrospective cohorts and prospective screen-detected cohorts should be considered.

BACKGROUND: With increased time and quality pressures, it may be more difficult for residents in cardiothoracic surgery residency programs to get independent operative experience. That may lead residents to inaccurately report their role as "surgeon" to meet American Board of Thoracic Surgery (ABTS) case requirements. METHODS: The 2013 In-Training Examination surveyed 312 cardiothoracic surgery residents and was used to contrast residents in traditional 2-year and 3-year cardiothoracic surgery residencies (traditional, n = 216) with those in 6-year integrated or 3+4-year programs (integrated, n = 96). RESULTS: Traditional program residents reported a higher percentage of cases that met the ABTS criteria of surgeon than did integrated program residents (p = 0.05) but were less likely to meet requirements if all cases were logged accurately (p = 0.03). The majority of residents in each program believed that their case log accurately reflected their experience as "surgeon." Residents who tended to log cases incorrectly had lower self-reported 2012 In-Training Examination percentiles, were less likely to meet case requirements if logged properly, and felt less prepared for board examinations and eventual practice compared with residents who logged cases correctly (all p < 0.001). Residents who believed they would not meet case requirements if logged correctly cited limited surgical opportunities, poor case diversity, and a compromised training environment but not the 80-hour work week, excessive simulation, or disproportionate number of complex cases as causes. CONCLUSIONS: Overall cardiothoracic surgery residents appear to be satisfied with their training. There were specific subsets of trainees in both traditional and Integrated programs that are misrepresenting their role on cases because they otherwise may not meet the requirements.

BACKGROUND: The impact of factors influencing career choice by cardiothoracic surgery (CTS) trainees remains poorly defined in the modern era. We sought to examine the associations between CTS trainee characteristics and future career aspirations. METHODS: The 2012 Thoracic Surgery In-Training Examination survey results were used to categorize responders according to career interest: congenital, adult cardiac, mixed cardiac/thoracic, and general thoracic surgery. Univariate and multivariable analyses were used to identify and analyze characteristics associated with career interest categories. RESULTS: With a 100% response rate, 300 responses from trainees in programs accredited by the Accreditation Council for Graduate Medical Education were included in the analysis. Multinomial logistic regression identified three factors associated with career choice in CTS: level of training (p < 0.001), type of training pathway (p < 0.001), and primary motivating factor to pursue CTS (p = 0.002). Trainees interested in general thoracic surgery were more likely to commit to CTS during their senior years of general surgery training and were more likely to enroll in 2-year or 3-year traditional fellowships, whereas individuals pursuing adult or congenital cardiac surgery were more likely to commit earlier during training and were more commonly interested in 6-year integrated or joint training pathways. Moreover, trainees interested in general thoracic surgery were predominantly influenced by early mentorship (p = 0.025 vs adult cardiac), and trainees interested in adult cardiac surgery were more likely to be influenced by types of operations (p = 0.047 vs general thoracic). CONCLUSIONS: Career choice in CTS appears strongly associated with level of training, exposure to mentors, and training paradigm. These results demonstrate the importance of maintaining all four currently approved training pathways to retain balance and diversity in future CTS practices.

BACKGROUND: During the past decade, cardiothoracic surgery (CTS) education has undergone tremendous change with the advent of new technologies and the implementation of integrated programs, to name a few. The goal of this study was to assess how residents' career paths, training, and perceptions changed during this period. METHODS: The 2006 to 2014 surveys accompanying the Thoracic Surgery Residents Association/Thoracic Surgery Directors' Association in-training examination taken by CTS residents were analyzed, along with a 2003 survey of graduating CTS residents. Of 2,563 residents surveyed, 2,434 (95%) responded. RESULTS: During the decade, fewer residents were interested in mixed adult cardiac/thoracic practice (20% in 2014 vs 52% in 2003, p = 0.004), more planned on additional training (10% in 2003 vs 41% to 47% from 2011 to 2014), and the frequent use of simulation increased from 1% in 2009 to 24% in 2012 (p < 0.001). More residents recommended CTS to potential trainees (79% in 2014 vs 65% in 2010, p = 0.007). Job offers increased from a low of 12% in 2008 with three or more offers to 34% in 2014. Debt increased from 0% with more than $200,000 in 2003 to 40% in 2013 (p < 0.001). Compared with residents in traditional programs, more integrated residents in 2014 were interested in adult cardiac surgery (53% vs 31%) and congenital surgery (22% vs 7%), fewer were interested in general thoracic surgery (5% vs 31%, p < 0.001), and more planned on additional training (66% vs 36%, p < 0.001). CONCLUSIONS: With the evolution in CTS over the last decade, residents' training and career paths have changed substantially, with increased specialization and simulation accompanied by increased resident satisfaction and an improved job market.

OBJECTIVE: Failure of anastomotic healing is a rare but serious complication of laryngotracheal resection. Treatment options include reoperation, tracheostomy, or T-tube placement. Hyperbaric oxygen therapy (HBOT) is the delivery of 100% O2 at pressures greater than 1 atm, and has been shown to enhance wound healing after tracheal resection in animal models. To date, there have been no reports describing its usefulness in humans after tracheal resection. METHODS: Five consecutive patients with varying degrees of failed anastomotic healing, from necrotic cartilage to partial separation identified by bronchoscopy were treated with HBOT. HBOT was administered for 90 minutes via a hyperbaric chamber pressurized to 2 atm with 100% oxygen. Patients were treated with daily or twice daily HBOT. Four of 5 patients had buttressing of the anastomosis by strap muscle at the initial surgery. RESULTS: All patients had evidence of anastomotic healing on bronchoscopy. None of the patients in this series required tracheostomy, T-tube, or reoperation after initiation of HBOT. On average it took 9.6 days for healing to occur (5-14 days). The size of the anastomotic defect ranged between 3 and 13 mm. One patient required bilateral tympanostomy tubes for inner ear discomfort and experienced blurry vision as complications of HBOT. One patient developed tracheal stenosis from granulation tissue that required bronchoscopic debridement. CONCLUSIONS: In select patients with anastomotic complications after tracheal resection, HBOT may aid in healing and avoid tracheostomy. Future investigations are necessary to further define the benefits of HBOT in the management of airway anastomotic complications.
