RESUMO
BACKGROUND: The treatment of symptomatic pseudarthrosis via posterior-only approaches in the setting of neurofibromatosis 1 (NF1) is challenging due to dural ectasias, resulting in erosion of the posterior elements. The purpose of this report is to illustrate a minimally invasive method for performing anterior thoracic fusion for pseudarthrosis in a patient with NF1-associated scoliosis and dysplastic posterior elements. To the best of our knowledge, this is the first documented case of using video-assisted thoracoscopic lateral interbody fusion to treat pseudarthrosis for NF1-associated spinal deformity. CASE DESCRIPTION: The patient underwent video-assisted thoracoscopic anterior spinal fusion via a direct lateral interbody approach with interbody cage placement at T10-T11 and T11-T12, followed by revision of his posterior spinal fusion and instrumentation. The patient had an uneventful postoperative course. At 6 months of follow-up, the patient had complete resolution of his preoperative symptoms and had returned to full-time work with no complaints. At 3 years postoperatively, the patient reported being satisfied with the operation and had continued to work full-time without restrictions. CONCLUSIONS: To the best of our knowledge, this is the first report of pseudarthrosis in the setting of NF1-associated scoliosis treated via minimally invasive anterior thoracic fusion facilitated by video-assisted thoracoscopic surgery. This is a powerful technique that allows for safe access for anterior thoracic fusion in the setting of dysplastic posterior anatomy and poor posterior bone stock.

Importance: Minimally invasive esophagectomy (MIE) is a complex procedure with substantial learning curves. In other complex minimally invasive procedures, suboptimal surgical performance has convincingly been associated with less favorable patient outcomes as assessed by peer review of the surgical procedure. Objective: To develop and validate a procedure-specific competency assessment tool (CAT) for MIE. Design, Setting, and Participants: In this international quality improvement study, a procedure-specific MIE-CAT was developed and validated. The MIE-CAT contains 8 procedural phases, and 4 quality components per phase are scored with a Likert scale ranging from 1 to 4. For evaluation of the MIE-CAT, intraoperative MIE videos performed by a single surgical team in the Esophageal Center East Netherlands were peer reviewed by 18 independent international MIE experts (with more than 120 MIEs performed). Each video was assessed by 2 or 3 blinded experts to evaluate feasibility, content validity, reliability, and construct validity. MIE-CAT version 2 was composed with refined content aimed at improving interrater reliability. A total of 32 full-length MIE videos from patients who underwent MIE between 2011 and 2020 were analyzed. Data were analyzed from January 2021 to January 2023. Exposure: Performance assessment of transthoracic MIE with an intrathoracic anastomosis. Main Outcomes and Measures: Feasibility, content validity, interrater and intrarater reliability, and construct validity, including correlations with both experience of the surgical team and clinical parameters, of the developed MIE-CAT. Results: Experts found the MIE-CAT easy to understand and easy to use to grade surgical performance. The MIE-CAT demonstrated good intrarater reliability (range of intraclass correlation coefficients [ICCs], 0.807 [95% CI, 0.656 to 0.892] for quality component score to 0.898 [95% CI, 0.846 to 0.932] for phase score). Interrater reliability was moderate (range of ICCs, 0.536 [95% CI, -0.220 to 0.994] for total MIE-CAT score to 0.705 [95% CI, 0.473 to 0.846] for quality component score), and most discrepancies originated in the lymphadenectomy phases. Hypothesis testing for construct validity showed more than 75% of hypotheses correct: MIE-CAT performance scores correlated with experience of the surgical team (r = 0.288 to 0.622), blood loss (r = -0.034 to -0.545), operative time (r = -0.309 to -0.611), intraoperative complications (r = -0.052 to -0.319), and severe postoperative complications (r = -0.207 to -0.395). MIE-CAT version 2 increased usability. Interrater reliability improved but remained moderate (range of ICCs, 0.666 to 0.743), and most discrepancies between raters remained in the lymphadenectomy phases. Conclusions and Relevance: The MIE-CAT was developed and its feasibility, content validity, reliability, and construct validity were demonstrated. By providing insight into surgical performance of MIE, the MIE-CAT might be used for clinical, training, and research purposes.

BACKGROUND: Video-based assessment by experts may structurally measure surgical performance using procedure-specific competency assessment tools (CATs). A CAT for minimally invasive esophagectomy (MIE-CAT) was developed and validated previously. However, surgeon's time is scarce and video assessment is time-consuming and labor intensive. This study investigated non-procedure-specific assessment of MIE video clips by MIE experts and crowdsourcing, collective surgical performance evaluation by anonymous and untrained laypeople, to assist procedure-specific expert review. METHODS: Two surgical performance scoring frameworks were used to assess eight MIE videos. First, global performance was assessed with the non-procedure-specific Global Operative Assessment of Laparoscopic Skills (GOALS) of 64 procedural phase-based video clips < 10 min. Each clip was assessed by two MIE experts and > 30 crowd workers. Second, the same experts assessed procedure-specific performance with the MIE-CAT of the corresponding full-length video. Reliability and convergent validity of GOALS for MIE were investigated using hypothesis testing with correlations (experience, blood loss, operative time, and MIE-CAT). RESULTS: Less than 75% of hypothesized correlations between GOALS scores and experience of the surgical team (r < 0.3), blood loss (r = - 0.82 to 0.02), operative time (r = - 0.42 to 0.07), and the MIE-CAT scores (r = - 0.04 to 0.76) were met for both crowd workers and experts. Interestingly, experts' GOALS and MIE-CAT scores correlated strongly (r = 0.40 to 0.79), while crowd workers' GOALS and experts' MIE-CAT scores correlations were weak (r = - 0.04 to 0.49). Expert and crowd worker GOALS scores correlated poorly (ICC ≤ 0.42). CONCLUSION: GOALS assessments by crowd workers lacked convergent validity and showed poor reliability. It is likely that MIE is technically too difficult to assess for laypeople. Convergent validity of GOALS assessments by experts could also not be established. GOALS might not be comprehensive enough to assess detailed MIE performance. However, expert's GOALS and MIE-CAT scores strongly correlated indicating video clip (instead of full-length video) assessments could be useful to shorten assessment time.

BACKGROUND: The harm associated with imaging abnormalities related to lung cancer screening (LCS) is not well documented, especially outside the clinical trial and academic setting. RESEARCH QUESTION: What is the frequency of invasive procedures and complications associated with a community based LCS program, including procedures for false-positive and benign, but clinically important, incidental findings? STUDY DESIGN AND METHODS: We performed a single-center retrospective study of an LCS program at a nonuniversity teaching hospital from 2016 through 2019 to identify invasive procedures prompted by LCS results, including their indication and complications. RESULTS: Among 2,003 LCS participants, 58 patients (2.9%) received a diagnosis of lung cancer and 71 patients (3.5%) received a diagnosis of any malignancy. Invasive procedures were performed 160 times in 103 participants (5.1%), including 1.7% of those without malignancy. Eight invasive procedures (0.4% of participants), including four surgeries (12% of diagnostic lung resections), were performed for false-positive lung nodules. Only 1% of Lung Imaging Reporting and Data System category 4A nodules that proved benign were subject to an invasive procedure. Among those without malignancy, an invasive procedure was performed in eight participants for extrapulmonary false-positive findings (0.4%) and in 19 participants (0.9%) to evaluate incidental findings considered benign but clinically important. Procedures for the latter indication resulted in treatment, change in management, or diagnosis in 79% of individuals. Invasive procedures in those without malignancy resulted in three complications (0.15%). Seventy nonsurgical procedures (6% complication rate) and 48 thoracic surgeries (4% major complication rate) were performed in those with malignancy. INTERPRETATION: The use of invasive procedures to resolve false-positive findings was uncommon in the clinical practice of a nonuniversity LCS program that adhered to a nodule management algorithm and used a multidisciplinary approach. Incidental findings considered benign but clinically important resulted in invasive procedure rates that were similar to those for false-positive findings and frequently had clinical value.

BACKGROUND: Currently, little is known regarding the optimal technique for the abdominal phase of RAMIE. The aim of this study was to investigate the outcome of robot-assisted minimally invasive esophagectomy (RAMIE) in both the abdominal and thoracic phase (full RAMIE) compared to laparoscopy during the abdominal phase (hybrid laparoscopic RAMIE). METHODS: This retrospective propensity-score matched analysis of the International Upper Gastrointestinal International Robotic Association (UGIRA) database included 807 RAMIE procedures with intrathoracic anastomosis between 2017 and 2021 from 23 centers. RESULTS: After propensity-score matching, 296 hybrid laparoscopic RAMIE patients were compared to 296 full RAMIE patients. Both groups were equal regarding intraoperative blood loss (median 200 ml versus 197 ml, p = 0.6967), operational time (mean 430.3 min versus 417.7 min, p = 0.1032), conversion rate during abdominal phase (2.4% versus 1.7%, p = 0.560), radical resection (R0) rate (95.6% versus 96.3%, p = 0.8526) and total lymph node yield (mean 30.4 versus 29.5, p = 0.3834). The hybrid laparoscopic RAMIE group showed higher rates of anastomotic leakage (28.0% versus 16.6%, p = 0.001) and Clavien Dindo grade 3a or higher (45.3% versus 26.0%, p < 0.001). The length of stay on intensive care unit (median 3 days versus 2 days, p = 0.0005) and in-hospital (median 15 days versus 12 days, p < 0.0001) were longer for the hybrid laparoscopic RAMIE group. CONCLUSIONS: Hybrid laparoscopic RAMIE and full RAMIE were oncologically equivalent with a potential decrease of postoperative complications and shorter (intensive care) stay after full RAMIE.

To determine the impact of enhanced recovery after surgery (ERAS) pathway implementation on outcomes and cost of robotic- and video-assisted thoracoscopic (RATS and VATS) lobectomy. Retrospective review of 116 consecutive VATS and RATS lobectomies in the pre-ERAS (Oct 2018-Sep 2019) and ERAS (Oct 2019-Sep 2020) period. Multivariate analysis was used to determine the impact of ERAS and operative approach alone, and in combination, on length of hospital stay (LOS) and overall cost. Operative approach was 49.1% VATS, 50.9% RATS, with 44.8% pre-ERAS, and 55.2% ERAS (median age 68, 65.5% female). ERAS patients had shorter LOS (2.22 vs 3.45 days) and decreased total cost ($15,022 vs $20,155) compared with non-ERAS patients, while RATS was associated with decreased LOS (2.16 vs 4.19 days) and decreased total cost ($14,729 vs $20,484) compared with VATS. The combination of ERAS + RATS showed the shortest LOS and the lowest total cost (1.35 days and $13,588, P < 0.001 vs other combinations). On multivariate analysis, ERAS significantly decreased LOS (P = 0.001) and total cost (P = 0.003) compared with pre-ERAS patients; RATS significantly decreased LOS (P < 0.001) and total cost (P = 0.004) compared with VATS approach. ERAS implementation and robotic approach were independently associated with LOS reduction and cost savings in patients undergoing minimally invasive lobectomy. A combination of ERAS and RATS approach synergistically decreases LOS and overall cost.

BACKGROUND: ERAS guidelines have provided an effective recovery approach for esophagectomy. This study aimed to identify the relationship between the length of hospital stay (LOS) and compliance with clinical benchmarks of an established institutional ERAS program. METHODS: A single-center prospective database of esophageal cancer patients was retrospectively analyzed between January 2016 and January 2020. All patients underwent surgery within a standardized ERAS pathway for esophagectomy. Compliance with individual ERAS benchmarks and postoperative outcomes were evaluated according to patient's LOS; accelerated (≤ 6 days, AR), targeted (7-8 days, TR), and delayed recovery (≥ 9 days, DR). RESULTS: The study included 100 consecutive patients undergoing esophagectomy with a median LOS of 7 (3.8-40.8) days, and a 30-day readmission rate of 12.6%. LOS was not affected by comorbidities, tumor type or stage, neoadjuvant therapy, operative approach or anastomotic leak. Postoperative complications were 49.5%, and 90-day mortality was 3.8%. AR, TR, and DL were achieved by 45%, 31%, and 24% of patients, respectively. Postoperative morbidity differed significantly among groups, impacting LOS (p < 0.001). Overall compliance with ERAS protocol was 82.7% and adherence to specific benchmarks was initially (< 48 h) high, but significantly affected by postoperative complications afterwards. CONCLUSIONS: Adherence to recovery benchmarks in patients undergoing esophagectomy is most commonly impacted by postoperative complications. In esophageal cancer surgery, the adherence to ERAS benchmarks after esophagectomy should be regularly audited. Modification to ERAS protocols to increase application in patients with complications should be considered.

BACKGROUND/AIMS: Transoral incisionless fundoplication (TIF) is an accepted anatomic treatment for gastroesophageal reflux disease in selected patients. In this report, we analyze our institution's programmatic allocation of resources during the safe implementation of TIF as a new procedure. METHODS: A retrospective analysis of all patients who underwent TIF from January 2020 to February 2021 at our institution was performed. The process of initially allocating the operating room (OR) with overnight admission and postoperative esophagram for added safety, and subsequently transitioning TIF to the endoscopy suite (ES) as an outpatient procedure was described. Patient safety and outcomes were evaluated during transition. RESULTS: Thirty patients who underwent TIF were identified. The mean age was 51.2±16.0 years. TIF was performed in an OR in nine patients (30%) and 21 (70%) in the ES. All the OR patients were admitted overnight and had routine EG. In contrast, four (19%) from the ES group required clinically-indicated admission and three (14.2%) required esophagram. The mean procedure duration was significantly lower in the ES group (65.7 min vs. 84 min, p=0.02). CONCLUSION: A stepwise, resource-efficient process was described that allowed safe initiation of TIF as a new technique and its effective transition to a fully outpatient procedure.
RESUMO
Anastomotic leak (AL) is a severe complication after esophagectomy. Clinical presentation of AL is diverse and there is large practice variation regarding treatment of AL. This study aimed to explore different AL treatment strategies and their underlying rationale. This mixed-methods study consisted of an international survey among upper gastro-intestinal (GI) surgeons and focus groups with expert upper GI surgeons. The survey included 10 case vignettes and data sources were integrated after separate analysis. The survey was completed by 188 respondents (completion rate 69%) and 6 focus groups were conducted with 20 international experts. Prevention of mortality was the most important goal of primary treatment. Goals of secondary treatment were to promote tissue healing, return to oral feeding and safe hospital discharge. There was substantial variation in the preferred treatment principles (e.g. drainage or defect closure) and modalities (e.g. stent or endoVAC) within different presentations of AL. Patients with local symptoms were treated by supportive means only or by non-surgical drainage and/or defect closure. Drainage was routinely performed in patients with intrathoracic collections and often combined with defect closure. Patients with conduit necrosis were predominantly treated by resection and reconstruction of the anastomosis or by esophageal diversion. This mixed-methods study shows that overall treatment strategies for AL are determined by vitality of the conduit and presence of intrathoracic collections. There is large variation in preferred treatment principles and modalities. Future research may investigate optimal treatment for specific AL presentations and aim to develop consensus-based treatment guidelines for AL after esophagectomy.

BACKGROUND: Early nasogastric tube (NGT) removal is a component of enhanced recovery after surgery (ERAS) protocol for esophagectomy. The aim of this study is to assess a protocol-driven application of UGI contrast study to facilitate early NGT removal and direct a standardized therapeutic response in patients with evidence for delayed gastric conduit emptying (DGCE). METHODS: All patients undergoing esophagectomy between January 2017 and October 2019 were prospectively enrolled. Esophageal resections were performed through different surgical approaches involving gastric conduit reconstruction. A standardized clinical protocol (SCP) was systematically applied, which targeted a UGI contrast study on POD 2-3 to allow immediate NGT removal or initiate DGCE protocols. RESULTS: This study enrolled 50 patients undergoing open Ivor Lewis (42%), left thoracoabdominal (46%), and three-field procedure (12%) with gastric conduit reconstruction and either upper thoracic (66%) or cervical (34%) anastomosis. Jejunostomy was routinely placed while pyloric procedures were not performed. Patients achieving targeted contrast study (86%) demonstrated significantly earlier NGT removal (p-value 0.010), oral protocol initiation (0.001), and decreased length of hospital stay (6 vs 10 days, 0.024). Four patients (8%) presented with radiology signs of DCGE and underwent protocoled treatment, eventually achieving discharge similar to the overall study population (7 vs 8.5 days). CONCLUSIONS: Protocol-driven UGI contrast study can effectively provide objective data facilitating early NGT removal and discharge. Patients with DGCE can successfully undergo intervention to improve conduit emptying and adhere to ERAS discharge goals.

Opioid therapy has been the mainstay therapy of post-operative pain management in thoracic surgery patients. With the high incidence of chronic pain in thoracic surgery patients and adverse effects of opioids, we examined the safety and efficacy of cryoneurolysis as an adjunct for narcotic-free pain management in robotic-assisted thoracoscopic lobectomies. Ten consecutive patients undergoing robotic-assisted (DaVinci) pulmonary resection and cryoneurolysis were compared to ten patients managed without intraoperative cryoneurolysis. All patients received multimodal pain regimen including paravertebral blocks as per our institutional enhanced recovery pathway. Patients with chronic pain and chronic opioid use were excluded. We compared inpatient and outpatient opioid consumption measured in morphine equivalents (mme), incidence of opioid-free outpatient recovery, and adverse events. The two groups did not differ significantly in terms of baseline demographics. Both inpatient (88.13 vs 26.92 mme) and outpatient (118.5 vs 34.5 mme) use of narcotics were significantly lower in the cryoneurolysis group (p < 0.05) with seven of ten patients receiving cryoneurolysis able to recover without the use of opioids in the outpatient setting, compared to two in the control group. One patient reported post-operative neuralgia in each cryoneurolysis and control group. There were no readmissions in either group and mean length of stay was identical at 1.7 days in control group and 1.1 days in experimental group (p = 0.33). The use of intraoperative intercostal cryoneurolysis may safely reduce the utilization of outpatient opioids in patients undergoing robotic-assisted thoracoscopic surgery. A randomized controlled trial is warranted to validate these findings in a larger cohort of patients.

Esophageal surgery is historically associated with adverse postoperative outcomes. Selected high-volume centers have previously reported the effect on clinical outcomes following the adoption of a standardized clinical pathway (SCP). This meta-analysis aims to evaluate the current literature to document the effect of SCP and enhanced recovery after surgery (ERAS) on esophagectomy outcomes. A literature search was conducted through the main search engines (PubMed, Embase, Medline, and Cochrane database) in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. All eligible comparative studies (randomized control trial, prospective, retrospective, and combined) were identified and assessed based on Methodological Index for Non-Randomized Studies and Jadad quality criteria. Data concerning overall morbidity, early mortality, and length of stay (LOS) were primarily collected and compared. Secondary outcomes included anastomotic leaks, pulmonary complications, and readmission rate. Twenty-six articles (including five randomized controlled trials and six prospective trials) were included in the analysis. Overall study quality was moderate and the included studies utilized a variable approach to SCP. No statistically significant differences were found between groups in terms of overall morbidity, postoperative mortality, anastomotic leak, and readmission rates. Significant improvements included pulmonary complications (odds ratios [OR] 0.66, 95% confidence interval [CI] 0.49-0.94) and hospital LOS (OR -3.68, 95% CI -4.49 to -2.87). Previous reports of SCP within esophagectomy programs have demonstrated clinical improvements in postoperative pulmonary complications and LOS. Given the high heterogeneity historically demonstrated within SCPs, further improvement in outcomes should be expected following the adoption of standardized ERAS guidelines.

OBJECTIVE: This international multicenter study by the Upper GI International Robotic Association aimed to gain insight in current techniques and outcomes of RAMIE worldwide. BACKGROUND: Current evidence for RAMIE originates from single-center studies, which may not be generalizable to the international multicenter experience. METHODS: Twenty centers from Europe, Asia, North-America, and South-America participated from 2016 to 2019. Main endpoints included the surgical techniques, clinical outcomes, and early oncological results of ramie. RESULTS: A total of 856 patients undergoing transthoracic RAMIE were included. Robotic surgery was applied for both the thoracic and abdominal phase (45%), only the thoracic phase (49%), or only the abdominal phase (6%). In most cases, the mediastinal lymphadenectomy included the low paraesophageal nodes (n=815, 95%), subcarinal nodes (n = 774, 90%), and paratracheal nodes (n = 537, 63%). When paratracheal lymphadenectomy was performed during an Ivor Lewis or a McKeown RAMIE procedure, recurrent laryngeal nerve injury occurred in 3% and 11% of patients, respectively. Circular stapled (52%), hand-sewn (30%), and linear stapled (18%) anastomotic techniques were used. In Ivor Lewis RAMIE, robot-assisted hand-sewing showed the highest anastomotic leakage rate (33%), while lower rates were observed with circular stapling (17%) and linear stapling (15%). In McKeown RAMIE, a hand-sewn anastomotic technique showed the highest leakage rate (27%), followed by linear stapling (18%) and circular stapling (6%). CONCLUSION: This study is the first to provide an overview of the current techniques and outcomes of transthoracic RAMIE worldwide. Although these results indicate high quality of the procedure, the optimal approach should be further defined.

BACKGROUND: Paravertebral pain catheters have been shown to be equally effective as epidural pain catheters for postoperative analgesia after thoracic surgery with the possible additional benefit of less hemodynamic effect. However, a methodology for verifying correct paravertebral catheter placement has not been tested or objectively confirmed in previous studies. The aim of the current study was to describe a technique to confirm the correct position of a paravertebral pain catheter using a contrast-enhanced paravertebrogram. METHODS: A retrospective cohort proof of concept study was performed including 10 consecutive patients undergoing elective thoracic surgery with radiographic contrast-enhanced confirmation of intraoperative paravertebral catheter placement (paravertebrogram). RESULTS: The results of the paravertebrograms, which were done in the operating room at the end of the procedure, verified correct paravertebral catheter placement in 10 of 10 patients. The radiographs documented dissemination of local anesthetic within the paravertebral space. CONCLUSION: This proof of concept study demonstrated that a contrast-enhanced paravertebrogram could be used in conjunction with standard postoperative chest radiography to add valuable information for the assessment of paravertebral catheter placement. This technique has the potential to increase the accuracy and efficiency of postoperative analgesia, and to set a quality standard for future studies of paravertebral pain catheters.

Paraesophageal hiatal hernias (PEHs) are most commonly associated with gastrointestinal symptoms; less widely appreciated is their potentially important influence on respiratory function. We hypothesize that surgical repair of PEH will significantly improve not only gastrointestinal symptoms, but also preoperative dyspnea and spirometry scores. A prospective Institutional Review Board-approved database was used to review all patients undergoing PEH repair from 2000 to 2016. Patients with pre- and postoperative pulmonary function tests assessed by spirometry were included. Postoperative changes in spirometry measurements were compared to PEH size as reflected by the percentage of intrathoracic stomach observed on preoperative contrast studies. Patients were stratified according to improvement in forced expiratory volume in 1 second (FEV1). Patients with >12% ('significant') improvement in FEV1 after surgery were compared to the remaining patient population. In total, 299 patients met the inclusion criteria. Symptomatic improvement in respiratory function was noted in all patients after PEH repair. Age, gender, BMI, presenting symptoms, Charlson comorbidity index as well as preoperative comorbidities did not significantly impact the functional outcome. Spirometry results improved in 80% of the patients, 21% of whom showed an improvement of >20% compared to the preoperative level. 'Significant' improvement in respiratory function was seen in 122 of 299 (41%) patients. Patients presenting with moderate and severe preoperative pulmonary obstruction demonstrated 'significant' improvement in FEV1 in 48% and 40% of cases, respectively. Large PEHs, characterized by a percentage of intrathoracic stomach >75%, was strongly associated with 'significant' improvement in FEV1 (P = 0.001). PEHs can impact subjective and objective respiratory status and surgical repair can result in a significant improvement in dyspnea and pulmonary function score that is independent of preoperative pulmonary disease. Gastric herniation of more than 75% was associated with higher possibility for improvement of pulmonary function tests. Patients with persistent and unexplained dyspnea and coexistent PEH should be assessed by an experienced surgeon for consideration of elective repair.

BACKGROUND: The role of sublobar resection in the treatment of pulmonary typical carcinoids is controversial. This study aims to compare long-term outcomes between sublobar and lobar resections in patients with peripheral typical carcinoid. METHODS: We retrospectively compared consecutive patients who underwent curative sublobar resection with patients who underwent lobectomy for cT1-3 N0 M0 peripheral pulmonary typical carcinoid in eight centers between 2000 and 2015. Primary outcomes were rates and patterns of recurrence and overall survival. Cox regression modeling was performed to identify factors influencing overall survival and recurrence. Propensity score analysis was done, and overall survival was compared between the two groups. RESULTS: In all, 177 patients were analyzed, consisting of 74 sublobar resections and 103 lobectomies, with a total of 857 person-years of follow-up. The R1 resection rates were 7% and 1% after sublobar resection and lobectomy, respectively (P = .08). One of 5 patients with sublobar R1 resection had recurrence. Recurrence rate was 0.02 (95% confidence interval [CI]: 0.009 to 0.044) per person-year of follow-up after sublobar resection and 0.008 (95% CI: 0.003 to 0.02) after lobectomy (P = .15). Five-year survival rates were 91.7% (95% CI: 78.5% to 96.9%) and 97.4% (95% CI: 90.1% to 99.4%) after sublobar and lobar resection, respectively (P = .08). Extent of resection was not a predictor of recurrence or survival. Propensity score analysis confirmed a similar survival and freedom from recurrence between the two groups. CONCLUSIONS: Sublobar resection of peripheral cT1-3 N0 M0 pulmonary typical carcinoid was not associated with worse short- or long-term outcomes compared with lobectomy. In select patients, sublobar resection may be considered for treatment of peripheral typical carcinoids if an R0 resection is obtained.

BACKGROUND: Minimal knowledge exists regarding the outcome, prognosis and optimal treatment strategy for patients with pulmonary large cell neuroendocrine carcinomas (LCNEC) due to their rarity. We aimed to identify factors affecting survival and recurrence after resection to inform current treatment strategies. METHODS: We retrospectively reviewed 72 patients who had undergone a curative resection for LCNEC in 8 centers between 2000 and 2015. Univariable and multivariable analyses were performed to identify the factors influencing recurrence, disease-specific survival and overall survival. These included age, gender, previous malignancy, ECOG performance status, symptoms at diagnosis, extent of resection, extent of lymphadenectomy, additional chemo- and/or radiotherapy, tumor location, tumor size, pT, pleural invasion, pN and pStage. RESULTS: Median follow-up was 47 (95%CI 41-79) months; 5-year disease-specific and overall survival rates were 57.6% (95%CI 41.3-70.9) and 47.4% (95%CI 32.3-61.1). There were 22 systemic recurrences and 12 loco-regional recurrences. Tumor size was an independent prognostic factor for systemic recurrence [HR: 1.20 (95%CI 1.01-1.41); p = 0.03] with a threshold value of 3 cm (AUC = 0.71). For tumors ≤3 cm and >3 cm, 5-year freedom from systemic recurrence was 79.2% (95%CI 43.6-93.6) and 38.2% (95%CI 20.6-55.6) (p < 0.001) and 5-year disease-specific survival was 60.7% (95%CI 35.1-78.8) and 54.2% (95%CI 32.6-71.6) (p = 0.31), respectively. CONCLUSIONS: A large proportion of patients with surgically resected LCNEC will develop systemic recurrence after resection. Patients with tumors >3 cm have a significantly higher rate of systemic recurrence suggesting that adjuvant chemotherapy should be considered after complete resection of LCNEC >3 cm, even in the absence of nodal involvement.

BACKGROUND: Postoperative recovery is an important measure in thoracic operations. Personal activity monitors can be used to track progress in the preoperative and postoperative settings. This study investigates associations of preoperative activity, lung resection extent, and operative approach with inpatient and outpatient functional recovery as measured by activity monitors. METHODS: In this prospective observational cohort study, patients undergoing lung resection at a single institution wore activity monitors 30 days before through 30 days after operation (between July 2015 and May 2017). Activity was recorded as steps per day, and each patient served as his or her own baseline. Patients were clustered into three activity level groups. Associations among preoperative and postoperative activity, length of stay (LOS), and operative approach were assessed by using generalized regression models with adjustment for patient demographic and clinical characteristics and operative details. RESULTS: Sixty-six patients comprised the study cohort and were grouped by average preoperative activity: low, 21 patients (31.8%); moderate, 27 patients (40.9%); and high, 18 patients (27.3%). The mean age was 66.1 ± 11.6 years; 32 patients (48.5%) were women. Sex, comorbidity, resection extent, and operative approach did not differ among groups. After adjustment for age, comorbidities, resection extent, operative approach, and complications, higher levels of preoperative activity were independently associated with higher postoperative activity in both inpatient and outpatient settings (ß = 1.11, 95% confidence interval [CI]: 1.00 to 1.22, p = 0.04; ß = 1.18, 95% CI: 1.07 to 1.30, p = 0.001) but not LOS. CONCLUSIONS: LOS is not associated with measures of preoperative or postoperative physical activity after adjustment for several factors. However, the association between preoperative activity and postoperative activity, irrespective of age, operative approach, resection extent, and other factors, offers a potential framework for designing recovery trajectory pathways and intervention development in both postoperative inpatient and outpatient settings.

BACKGROUND: Abnormal esophageal peristalsis diagnosed by high-resolution manometry is frequently found as part of the preoperative evaluation of patients with paraesophageal hernia (PEH). Currently, the clinical relevance of these findings is largely unknown. STUDY DESIGN: From 2013 to 2016, two hundred and twelve patients undergoing PEH repair were prospectively recorded in an IRB-approved database. Preoperative high-resolution manometry was available for reanalysis according to the latest Chicago Classification (version 3.0) in 200 patients. Outcomes in patients with abnormal motility (AM) were compared with patients with normal motility (NM). RESULTS: Abnormal motility was documented in 106 (53%) patients. Abnormal motility was associated with older age (72 vs 69 years) and increased age-adjusted Charlson Comorbidity Index (both, p = 0.04). Compared with preoperative symptoms, postoperative retrosternal pain in AM vs NM patients went from 79% to 5% vs 75% to 2%, regurgitation from 52% to 2% vs 59% to 0%, and dysphagia from 56% to 7% vs 67% to 7%. An esophagogram was performed at a median of 4 months and 3.5 months postoperatively. Postoperative reflux in AM vs NM went from 54% to 21% vs 57% to 16%, and abnormal esophageal motility, visually assessed during the esophagogram, was stable (52% to 56% vs 41% to 48% for AM vs NM, respectively). CONCLUSIONS: Patients found to have AM according to the Chicago classification before surgical repair of PEH demonstrated similar symptomatic improvement compared with patients with NM. Selective motility disorders diagnosed by preoperative high-resolution manometry should not preclude surgical repair of giant PEHs.

OBJECTIVE: Prior studies have reported underuse of-but not variability in-invasive mediastinal staging in the pretreatment evaluation of patients with lung cancer. We sought to compare rates of invasive mediastinal staging for lung cancer across hospitals participating in a regional quality improvement and research collaborative. METHODS: We conducted a retrospective study (2011-2013) of patients undergoing resected lung cancer from the Surgical Clinical Outcomes and Assessment Program in Washington State. Invasive mediastinal staging included mediastinoscopy and/or endobronchial/esophageal ultrasound-guided nodal aspiration. We used a mixed-effects model to mitigate the influence of small sample sizes at any 1 hospital on rates of invasive staging and to adjust for hospital-level differences in the frequency of clinical stage IA disease. RESULTS: A total of 406 patients (mean age, 68 years; 69% clinical stage IA; and 67% lobectomy) underwent resection at 5 hospitals (4 community and 1 academic). Invasive staging occurred in 66% of patients (95% confidence interval [CI], 61%-71%). CI inspection revealed that 2 hospitals performed invasive staging significantly more often than the overall average (94%, [95% CI, 89%-96%] and 84% [95% CI, 78%-88%]), whereas 2 hospitals performed invasive staging significantly less often than overall average (31% [95% CI, 21%-44%] and 17% [95% CI, 7%-36%]). CONCLUSIONS: Rates of invasive mediastinal staging varied significantly across hospitals providing surgical care for patients with lung cancer. Future studies that aim to understand the reasons underlying variability in care may inform quality improvement initiatives or lead to the development of novel staging algorithms.
