Prognosis of triple-negative breast cancer associated with pregnancy: A propensity score-matched analysis from the French CALG (Cancer Associé à la Grossesse) network

IntroductionTriple-negative (TN) breast cancer represents one third of pregnancy-associated breast cancers (PABC). The aims of the current study were to describe oncological and obstetrical outcomes of patients with TN-PABC and to compare their prognosis with TN-non-PABC patients using a propensity score.Materials and methodsBetween January 2005 and December 2020, data of patients with histologically proven TN-PABC were collected and compared with data of TN-non-PABC patients under the age of 46 years diagnosed during the same period using a propensity score (PS).ResultsAfter PS matching (tumor size and lymph node involvement),there were 59 patients in each group. The median follow-up was 14 months (IQR 4.8–40.1) for the TN-PABC group and 60 months (IQR 30.7–101.4) for the TN-non-PABC group. Eight recurrences occurred in the TN-PABC group and 10 in the TN-non-PABC group (adjusted OR (AOR) = 0.60 (0.21–1.60), HR (Cox adjusted model- AHR) = 1.25 (0.53–2.94)). Two patients died in the TN-PABC group, and six in the TN-non-PABC group with an AOR = 0.23 (0.03–1.01) and an AHR = 0.58 (0.12–2.69). All the patients diagnosed during the second (n = 17) and third trimesters (n = 28) continued their pregnancies, with a median term at delivery of 38 WG (IQR 36–39). All patients gave birth to healthy newborns.ConclusionAlthough the TN subtype is associated with poor prognosis in pregnant patients due to advanced stage at diagnosis and high lymph node involvement, our PS-matched case-control study showed that pregnancy per se does not worsen the prognosis in terms of recurrence-free and overall survival.     

Hirschsprung-associated inflammatory bowel disease: A multicenter study from the APSA Hirschsprung disease interest group

Background/PurposeA small number of Hirschsprung disease (HD) patients develop inflammatory bowel disease (IBD)-like symptoms after pullthrough surgery. The etiology and pathophysiology of Hirschsprung-associated IBD (HD-IBD) remains unknown. This study aims to further characterize HD-IBD, to identify potential risk factors and to evaluate response to treatment in a large group of patients.MethodsRetrospective study of patients diagnosed with IBD after pullthrough surgery between 2000 and 2021 at 17 institutions. Data regarding clinical presentation and course of HD and IBD were reviewed. Effectiveness of medical therapy for IBD was recorded using a Likert scale.ResultsThere were 55 patients (78% male). 50% (n = 28) had long segment disease. Hirschsprung-associated enterocolitis (HAEC) was reported in 68% (n = 36). Ten patients (18%) had Trisomy 21. IBD was diagnosed after age 5 in 63% (n = 34). IBD presentation consisted of colonic or small bowel inflammation resembling IBD in 69% (n = 38), unexplained or persistent fistula in 18% (n = 10) and unexplained HAEC >5 years old or unresponsive to standard treatment in 13% (n = 7). Biological agents were the most effective (80%) medications. A third of patients required a surgical procedure for IBD.ConclusionMore than half of the patients were diagnosed with HD-IBD after 5 years old. Long segment disease, HAEC after pull through operation and trisomy 21 may represent risk factors for this condition. Investigation for possible IBD should be considered in children with unexplained fistulae, HAEC beyond the age of 5 or unresponsive to standard therapy, and symptoms suggestive of IBD. Biological agents were the most effective medical treatment.Level of EvidenceLevel 4     

Single-center comparison of outcomes between laparoscopic appendectomy and transumbilical laparoscopic assisted appendectomy

PurposeAppendectomy is the most common pediatric emergency surgery performed to date. This study compared outcomes between laparoscopic appendectomy (LA) and transumbilical laparoscopic assisted appendectomy (TULAA) for 1154 uncomplicated patients across 5 years at a single institution. Primary outcomes include length of stay (LOS), post-operative complications, pain score, and operating room (OR) time.MethodsDemographic and clinical data was collected for 1154 eligible patients treated for uncomplicated appendicitis between August 2014–October 2019, with 830 patients in the LA group, and 324 in the TULAA group. Mixed effects modeling procedure using logistic and linear regression examined the effect of surgery type on the four primary outcomes after adjustment for potential clustering effect of surgeon and confounding factors.ResultsOf 1154 patients, 62.7% were male, and mean (SD) age was 10.9 (3.6) years. Median [IQR] LOS was 28.0 h [22.0, 36.0], mean (SD) OR time was 29.0 (10.0) minutes, and median [IQR] pain at maximum level was 5.5 (2.7). The complication rate overall was <5.0% and did not differ between TULAA and LA groups (p > 0.05). OR time was reduced by an average of 5.2 min in the TULAA group (p < 0.001), pain did not differ between groups overall (p > 0.05), and patients were more likely to be discharged within 24 h in patients who underwent TULAA (OR = 5.3 [1.6, 17.4], p = 0.007).ConclusionRetrospective analysis of 1154 pediatric appendectomies, found no difference in complications between single- and three-incision laparoscopic procedures (TULAA vs. LA). Findings suggest TULAA is a safe procedure for acute appendicitis in pediatrics.Level of EvidenceIV.     

Open hemiarch versus clamped ascending aorta replacement for aortopathy during initial bicuspid aortic valve replacement

BackgroundThere is controversy regarding the extent of aortic resection necessary in patients with aortopathy related to bicuspid aortic valve disease. To address this issue, we reviewed our experience in patients undergoing ascending aorta replacement during bicuspid aortic valve replacement.MethodsWe reviewed 702 patients who underwent ascending aorta replacement at the time of initial nonemergent native bicuspid aortic valve replacement at our institution between January 2000 and June 2017. Treatment cohorts included an open hemiarch replacement group (n = 225; 32%) and a clamped ascending aorta replacement group (n = 477; 68%).ResultsMedian patient age was 60 years (interquartile range [IQR], 51-67 years), female sex was present in 113 patients (16%), ejection fraction was 62% (IQR, 56%-66%), and aortic arch diameter was 33 mm (IQR, 29-36 mm). Cardiopulmonary bypass time was longer in the hemiarch replacement group (188 minutes vs 97 minutes; P < .001). Procedure-related complications (36%) and mortality (<1%) were similar in the 2 groups; however, the hemiarch group had an increased odds of blood transfusion (odds ratio, 1.62; 95% confidence interval [CI], 1.15-2.28; P = .006). The median duration of follow-up was 6.0 years (95% CI, 5.3-6.8 years). Overall survival was 94 ± 1% at 5 years and 80 ± 2% at 10 years. Multivariable analysis demonstrated similar survival in the 2 groups (hazard ratio, 0.83; 95% CI, 0.51-1.33; P = .439). No repeat aortic arch operations were done for aortopathy over the duration of clinical follow-up.ConclusionsCompared with patients in the clamped ascending aorta replacement group, patients in the hemi-arch replacement group had longer cardiopulmonary bypass and aortic cross-clamp times, along with an increased risk of blood transfusion, but similar freedom from repeat aortic arch operation and survival. We identified no advantage of performing hemiarch replacement in the absence of aortic arch dilation.     

Management of Primary Spontaneous Pneumothorax in Children: A Single Institution Protocol Analysis

BackgroundThe Midwest Pediatric Surgery Consortium (MWPSC) suggested a simple aspiration of primary spontaneous pneumothorax (PSP) protocol, failing which, Video-Assisted Thoracoscopic Surgery (VATS) should be considered. We describe our outcomes using this suggested protocol.MethodsA single institution retrospective analysis was conducted on patients between 12 and 18 years who were diagnosed with PSP from 2016 to 2021. Initial management involved aspiration alone with a ≤12 F percutaneous thoracostomy tube followed by clamping of the tube and chest radiograph at 6 h. Success was defined as ≤2 cm distance between chest wall and lung at the apex and no air leak when the clamp was released. VATS followed if aspiration failed.ResultsFifty-nine patients were included. Median age was 16.8 years (IQR 15.9, 17.3). Aspiration was successful in 33% (20), while 66% (39) required VATS. The median LOS with successful aspiration was 20.4 h (IQR 16.8, 34.8), while median LOS after VATS was 3.1 days (IQR 2.6, 4). In comparison, in the MWPSC study, the mean LOS for those managed with a chest tube after failed aspiration was 6.0 days (±5.5). Recurrence after successful aspiration was 45% (n = 9), while recurrence after VATS was 25% (n = 10). Median time to recurrence after successful aspiration was sooner than that of the VATS group [16.6 days (IQR 5.4, 19.2) vs. 389.5 days (IQR 94.1, 907.0) p = 0.01].ConclusionSimple aspiration is safe and effective initial management for children with PSP, although most will require VATS. However, early VATS reduces length of stay and morbidity.Level of evidenceIV. Retrospective study.     

Twenty-year outcomes of minimally invasive direct coronary artery bypass surgery: The Leipzig experience

ObjectiveMinimally invasive direct coronary artery bypass (MIDCAB) surgery involving left anterior descending coronary artery grafting with the left internal thoracic artery through a left anterior small thoracotomy is being routinely performed in some specified centers for patients with isolated complex left anterior descending coronary artery disease, but very few reports regarding long-term outcomes exist in literature. Our study was aimed at assessing and analyzing the early and long-term outcomes of a large cohort of patients who underwent MIDCAB procedures and identifying the effects of changing trends in patient characteristics on early mortality.MethodsA total of 2667 patients, who underwent MIDCAB procedures between 1996 and 2018, were divided into 3 groups on the basis of the year of surgery: group A, 1996-2003 (n = 1333); group B, 2004-2010 (n = 627) and group C, 2011-2018 (n = 707). Groupwise characteristics and early postoperative outcomes were compared. Long-term survival for all patients was analyzed and predictors for late mortality were identified using Cox proportional hazards methods.ResultsThe mean age was 64.5 ± 10.9 years and 691 (25.9%) patients were female. Group C patients (log EuroSCORE I = 4.9 ± 6.9) were older with more cardiac risk factors and comorbidities than groups A (log EuroSCORE I = 3.1 ± 4.5) and B (log EuroSCORE I = 3.5 ± 4.7). Overall and groupwise in-hospital mortality was 0.9%, 1.0%, 0.6%, and 1.0% (P = .7), respectively. Overall 10-, 15-, and 20-year survival estimates for all patients were 77.7 ± 0.9%, 66.1 ± 1.2%, and 55.6 ± 1.6%, respectively.ConclusionsMIDCAB can be safely performed with very good early and long-term outcomes. In-hospital mortality remained constant over the 22-year period of the study despite worsening demographic profile of patients.     

Impact of left ventricular ejection fraction on the outcomes of open repair of descending thoracic and thoracoabdominal aneurysms

ObjectiveTo discern the impact of depressed left ventricular ejection fraction (LVEF) on the outcomes of open descending thoracic aneurysm (DTA) and thoracoabdominal aneurysms (TAAA) repair.MethodsRestricted cubic spline analysis was used to identify a threshold of LVEF, which corresponded to an increase in operative mortality and major adverse events (MAE: operative death, myocardial infarction, stroke, spinal cord injury, need for tracheostomy or dialysis). Logistic and Cox regression were performed to identify independent predictors of MAE, operative mortality, and survival.ResultsDTA/TAAA repair was performed in 833 patients between 1997 and 2018. Restricted cubic spline analysis showed that patients with LVEF <40% (n = 66) had an increased risk of MAE (odds ratio [OR], 2.17; 95% confidence interval [CI], 1.22-3.87; P < .01) and operative mortality (OR, 2.72; 95% CI, 1.21-6.12; P = .02) compared with the group with LVEF ≥40% (n = 767). The group with LVEF <40% had a worse preoperative profile (eg, coronary revascularization, 48.5% vs 17.3% [P < .01]; valvular disease, 82.8% vs 49.39% [P < .01]; renal insufficiency, 45.5% vs 26.1% [P < .01]; respiratory insufficiency, 36.4% vs 21.2% [P = .01]) and worse long-term survival (35.5% vs 44.7% at 10 years; P = .01). Nonetheless, on multivariate regression, depressed LVEF was not an independent predictor of operative mortality, MAE, or survival.ConclusionsLVEF is not an independent predictor of adverse events in surgery for DTA.     

Results of staged repair of aortic disease in patients with Marfan syndrome

ObjectiveWe present our open surgical strategies for staged replacement of the thoracic and thoracoabdominal aorta in patients with Marfan syndrome.MethodsBetween October 1999 and December 2017, 82 patients with Marfan syndrome underwent 118 aortic repairs. We divided the aorta into 4 segments for categorization: (1) the aortic root, (2) aortic arch, (3) descending thoracic, and (4) abdominal aorta. Procedures were categorized according to the types of surgery. Staged repair was defined as a subsequent operation on a different segment of the aorta after initial repair (n = 111, 94.1%), and reoperation was defined as an operation on the same segment (n = 7, 5.9%).ResultsThe mean age at initial operation was 41.7 ± 14.9 years. Staged repairs included aortic root replacement (n = 42, 36%), total arch replacement (n = 11, 9.3%), combined aortic root and total arch replacement (n = 13, 11%), descending aorta replacement (n = 4, 3.4%), thoracoabdominal aortic repair (n = 36, 31%), and extensive arch-descending or thoracoabdominal repair (n = 5, 4.2%). Four patients received 3 staged repairs. Operative mortality was 0.8% (1/118). Stroke occurred in 1.7% (2/118), and spinal cord injury occurred in 1.7% (2/117). Overall survival was 95.8 ± 2.4% at 10-years. Twenty-four patients underwent replacement of the whole aorta after 2.5 ± 3.8 years following initial repair.ConclusionsOur strategies for staged replacement of the thoracic and thoracoabdominal aorta in patients with Marfan syndrome resulted in excellent early- and long-term outcomes.     

Long-term outcomes of rigid ring versus De Vega annuloplasty for functional tricuspid regurgitation: A propensity score-matching analysis

ObjectiveThis study was conducted to compare the outcomes of rigid ring versus De Vega annuloplasty for the treatment of functional tricuspid regurgitation (TR).MethodsFrom 2003 to 2017, De Vega annuloplasty (group D) was used in 231 patients, and rigid ring annuloplasty (group R) was used in 204 patients for the treatment of functional TR during left-sided valve surgery. A propensity score-matching analysis was used to pair group D (n = 109) with group R (n = 109). The primary outcomes were long-term overall survival and cardiac death, and the secondary outcomes were tricuspid valve-related events and TR recurrence (TR moderate or severe). The follow-up data were complete in 99.6% (447 out of 449) of the patients with a follow-up duration of 102 months.ResultsThere were no differences in the overall survival and cardiac death between the propensity score-matched groups (P = .793 and P = .175, respectively) up to 14 years after surgery. Tricuspid valve-related events, including cardiac death, permanent pacemaker implantation, thromboembolism, bleeding and tricuspid valve reoperation were also similar between the 2 matched groups during the follow-up (P > .999). However, cumulative incidence of TR recurrence was significantly higher in group R than in group D (P = .007). Multivariate analysis indicated the annuloplasty method (De Vega) and preoperative TR grade as risk factors for late TR recurrence.ConclusionsIn functional TR, annuloplasty methods did not influence long-term overall survival, cardiac mortality, and tricuspid valve-related events. However, rigid ring annuloplasty showed less late TR recurrence. Rigid ring annuloplasty can be considered for the treatment of functional TR in terms of its better durability.     

Mortality after tricuspid valve procedures: A 27-year,single-center experience

ObjectiveTo assess mortality after tricuspid valve (TV) surgery in a large single-center patient cohort.MethodsData from 392 TV procedures performed between 1989 and 2015 in 388 adult patients were retrospectively reviewed. The patients were divided into groups according to the type of concomitant procedure, ie, coronary artery bypass grafting (CABG) (TV + CABG group; n = 87), other valve surgery (TV + valve group; n = 240), or an isolated TV procedure with or without another minor procedure (isolated TV group; n = 65), and the era of the operation, ie, 1989-2005 (n = 173) or 2006-2015 (n = 219). Control groups of patients who underwent other valve procedures and/or CABG during the same time periods were used for comparison.ResultsDuring the most recent era, the annual number of TV procedures increased 2.4-fold, mainly for TV + valve procedures (2.8-fold). Within the TV + valve group, a larger proportion of patients had mild-to-moderate tricuspid regurgitation (grade ≤2) compared with the first-time period (P = .001). The TV + CABG group had significantly greater mortality than both the other groups during both time periods, whereas isolated TV procedure had the lowest mortality rates with the exception of the TV + valve group during the most recent era (P = .41). Survival for patients undergoing TV + valve procedures has improved significantly during the last decade (P = .001) and was comparable with that for other valve operations during this period.ConclusionsIn the last decade, TV repair has been performed more frequently and at lower grades of tricuspid regurgitation compared with previously, and mortality after TV procedures has decreased.     

Successful Treatment of Fibro-Adipose Vascular Anomaly with Sirolimus

BackgroundThe purpose of this study was to present our initial experience in using sirolimus therapy to treat fibro-adipose vascular anomaly (FAVA).MethodsWe retrospectively reviewed the medical records of eight patients with FAVA who were treated with sirolimus at our hospital between July 2017 and October 2020.ResultsSix girls (75%) and two boys (25%) were included in the cohort; the average age was 8 years (range, 1–13 years). Vascular tumors developed mainly on the extremities, including the forearm (n = 2; 25.0%), calf (n = 4; 50.0%), and thigh (n = 2; 25.0%). The predominant symptoms included swelling of the lesion (n = 8; 100%), pain (n = 7; 87.5%), contracture (n = 3; 37.5%), and phlebectasia (n = 3; 37.5%). Magnetic resonance imaging was the primary method used for FAVA diagnosis, and all patients underwent enhanced MRI. All lesions were heterogeneous with hyperintense T1 signals. The fat-suppressed T2-weighted images also revealed heterogeneous hyperintense masses, thus indicating fibrofatty infiltration. All eight patients received a sirolimus treatment regimen after FAVA diagnosis. One patient underwent tumor resection but experienced recurrence, whereas the other six patients underwent biopsy. Histological examination revealed that the lesions consisted of fibrofatty tissue with abnormal venous channels and anomalous lymphatic vascular components. Sirolimus softened the masses and caused tumor shrinkage within 5.25 ± 2.6 weeks (range, 2–10 weeks) after treatment initiation. The tumors also involuted rapidly and became stable within 7.75 ± 2.25 months after treatment initiation (range, 6–12 months). All seven patients experiencing pain reported relief within 3.8 ± 1.8 weeks (range, 2–7 weeks) after initiation of sirolimus therapy. Sirolimus alleviated but did not fully resolve the contracture in three patients. Remarkably, five patients exhibited a complete response, and three patients exhibited a partial response. At the time of the last follow-up, three patients had begun to gradually taper off sirolimus after 24 months of treatment and maintained a low blood sirolimus concentration. No serious adverse effects were observed during treatment.ConclusionFAVA is a complex vascular malformation that appears to respond well to sirolimus treatment. Thus, sirolimus may be an effective and safe treatment for FAVA.Level of evidenceLEVEL IV.     

Preoperative tendon retraction,not smoking,is a risk factor for failure with continuity after rotator cuff repair

BackgroundSmoking is a poor prognostic factor for healing after rotator cuff repair and is associated with inferior results. We hypothesized that smokers would have higher recurrent tear rates and more postoperative myotendinous junction (MTJ) retraction in healed repairs than nonsmokers three months postoperatively.MethodsRotator cuff repairs (RCRs) were retrospectively reviewed over a 2-year period. Patients underwent magnetic resonance imaging (MRI) within 6 months prior to surgery and again at 3 months postoperatively. Seventy-nine patients were included and stratified by smokers versus nonsmokers. Baseline patient demographics, tear characteristics, and surgical factors were collected. Preoperative and postoperative MRIs were assessed to quantify the MTJ position and to establish the recurrent tear rate.ResultsFor the total cohort (nonsmokers, n = 56; smokers, n = 23), significant differences in age, race, and traumatic onset of injury existed between groups. There were no significant differences in recurrent tear between smokers (26%) and nonsmokers (27%), but nonsmokers were more satisfied. For patients with healed RCRs (nonsmokers, n = 41; smokers, n = 17), there were significant differences in race. On univariate analysis, nonsmokers had a significantly more lateral MTJ postoperatively (P = 0.05). On multivariable regression analysis, medialized postoperative MTJ position in healed cuffs was driven only by greater preoperative rotator cuff retraction preoperatively. There were no significant differences in MTJ position based on smoking status for patients with healed RCRs.ConclusionSmoking does not appear to be an independent risk factor for postoperative MTJ retraction in healed RCRs, also known as failure in continuity. Preoperative tear size and retraction play the biggest roles in predicting postoperative MTJ position, regardless of smoking status. There are no significant differences in patient-reported outcomes for patients with healed RCRs, but nonsmokers had more satisfaction following RCR in the total cohort.Level of EvidenceLevel III; Retrospective cohort study; Diagnostic study     

Are racial differences in hospital mortality after coronary artery bypass graft surgery real? A risk-adjusted meta-analysis

BackgroundDespite several reports, there are still conflicting data on the influence of ethnicity on mortality rates associated with coronary artery bypass grafting (CABG). We aimed to get further insights into the effect of race on mortality following CABG by performing a risk adjusted meta-analysis.MethodsRelevant studies were searched on PubMed, Embase, BioMed Central, and the Cochrane Central register. Pairwise meta-analysis was used to estimate the relative risk of hospital death of black, Hispanic, and Asian patients using white patients as reference. Risk adjusted meta-analytic estimates were obtained using generic inverse variance methods with random effect model.ResultsA total of 28 studies were selected for analysis. A total of 21 studies reported on hospital mortality in black (n = 222,892) versus white (n = 3,884,043) patients, 7 studies reported on Hispanic (n = 91,256) versus white (n = 1,458,524) and 9 studies reported on Asian (n = 27,820) versus white (n = 1,081,642). When compared with white patients, adjusted risk of hospital death was significantly greater for black patients (adjusted odds ratio [OR], 1.25; 95% confidence interval [CI], 1.13-1.39; P < .001), and not statistically different for Asian (OR, 1.33; 95% CI, 0.99-1.77; P = .05) and Hispanic patients (adjusted OR, 1.08; 95% CI, 0.94-1.23; P = .26). Meta-regression showed a significant trend toward lower mortality rates in most recent series in both black (P = .02) and white (P = .0007) and Asian (P = .01) but not for Hispanic (P = .41). However, as mortality rates were lower across the different races, the relative disadvantage between the study groups persisted, which may explain the lack of interaction between study period and race effect on mortality for black (adjusted P = .09), Asian (adjusted P = .63), and Hispanic (adjusted P = .97) patients.ConclusionsThe present meta-analysis showed that despite progress is being made in lowering in-hospital mortality rates among the major racial/ethnic groups, ethnical disparities in hospital mortality after CABG remain.     

Surgical outcomes of acute type A aortic dissection in patients undergoing cardiopulmonary resuscitation

ObjectivesThe surgical indications for acute type A aortic dissection (AAAD) in patients in cardiopulmonary arrest remain controversial. Outcomes of AAAD for patients who underwent cardiopulmonary resuscitation (CPR) were evaluated.MethodsBetween 2004 and 2018, of the 519 patients who underwent AAAD repair, 34 (6.6%) required CPR before or on starting AAAD repair. The patients were divided into 2 groups, survivors (n = 13) and nonsurvivors (n = 21), to compare the early operative outcomes, including mortality and neurological events.ResultsThe major cause of cardiovascular collapse requiring CPR was aortic rupture/cardiac tamponade (n = 21 [61.8%]), followed by coronary malperfusion (n = 12 [35.3%]) and acute aortic valve regurgitation (n = 3 [8.8%]). There were 3 (23.1%) patients in the survivors group and 11 (52.4%) in the nonsurvivors group who required ongoing CPR at the beginning of AAAD repair (P = .039). Of these patients, 1 survivor and 6 nonsurvivors could not achieve return of spontaneous circulation after pericardiotomy (P = .045). Although the duration from onset or arrival to the operating room was similar (P = .35 and P = .49, respectively), overall duration of CPR was shorter in survivors (10 minutes [range, 7.5-16 minutes] vs 16.5 minutes [range, 15-20 minutes]; P = .044). All survivors without any neurological deficits showed return of spontaneous circulation after pericardiotomy. Multivariate regression modeling showed that CPR duration >15 minutes was a significant risk factor for in-hospital mortality (P = .0040).ConclusionsCPR duration beyond 15 minutes may be a contraindication for AAAD repair. Moreover, we should reconsider surgery for patients who cannot achieve return of spontaneous circulation after pericardiotomy.     

Safety and feasibility of esophagectomy following combined immunotherapy and chemoradiotherapy for esophageal cancer

ObjectivesWe sought to determine the safety and feasibility of esophagectomy after neoadjuvant immunotherapy and chemoradiotherapy in clinical trial patients with locally advanced esophageal cancer.MethodsWe retrospectively identified patients who were treated with neoadjuvant immunotherapy and chemoradiotherapy (n = 25) or chemoradiotherapy alone (n = 143) at our institution between 2017 and 2020. The primary end point was risk of 30-day major complications (Clavien-Dindo classification system grade ≥ 3), which was assessed between groups using a multivariable log-binomial regression model to obtain adjusted relative risk ratios. Secondary end points were interval to surgery, 30-day readmission rate, and 30-day mortality.ResultsAll included patients successfully completed neoadjuvant therapy and underwent esophagectomy with negative margins. Age, sex, performance status, clinical stage, histologic subtype, procedure type, and operative approach were similar between groups. Neoadjuvant immunotherapy was not associated with a statistically significantly increased risk of developing a major pulmonary (relative risk, 1.43; 95% confidence interval, 0.53-3.84; P = .5), anastomotic (relative risk, 1.34; 95% confidence interval, 0.45-3.94; P = .6), or other complication (relative risk, 1.29; 95% confidence interval, 0.26-6.28; P = .8). Median (interquartile range) interval to surgery was 54 days (47-61 days) in the immune checkpoint inhibitor group versus 53 days (47-66 days) in the control group (P = .6). Minimally invasive approaches were successful in 72% of cases, with only 1 conversion. Thirty-day mortality and readmission rates were 0% and 17%, respectively, in the immune checkpoint inhibitor group and 1.4% and 13%, respectively, in the control group.ConclusionsOn the basis of our preliminary experience, esophagectomy appears to be safe and feasible following combined neoadjuvant immunotherapy and standard chemoradiotherapy for locally advanced esophageal cancer.     

Chest Wall Reconstruction in Pediatric Patients with Chest Wall Tumors: A Systematic Review

BackgroundResection of pediatric chest wall tumors can result in large defects requiring reconstruction for function and cosmesis. Multiple reconstructive methods have been described. We performed a systematic review of the literature to describe commonly used approaches and outcomes.MethodsA systematic literature search was performed for English-language publications describing chest wall tumor resection and reconstruction using implantable materials in patients ≤21 years, excluding soft tissue resection only, sternal resection, and reconstruction by primary repair or muscle flaps alone. Data were collected on diagnoses, reconstructive method, and outcomes. Rigid chest wall reconstruction was compared to mesh reconstruction.ResultsThere were 55 articles with 188 patients included. The median age was 12 years. Most tumors were malignant (n = 172, 91.5%), most commonly Ewing's sarcoma (n = 65, 34.6%), followed by unspecified sarcomas (n = 34, 18.1%), Askin's tumor (n = 16, 8.5%; a subset of Ewing's sarcoma) and osteosarcoma (n = 16, 8.5%). A median of 3 ribs were resected (range 1–12). Non-rigid meshes were most common (n = 138, 73.4%), followed by rigid prostheses (n = 50, 26.6%). There were 19 post-operative complications (16.8%) and 22.2% of patients developed scoliosis. There were no significant differences in complications (20.5% rigid vs. 10.6% non-rigid, p = 0.18) or scoliosis (22.7% vs. 14.0%, p = 0.23) by reconstruction method, but complications after rigid reconstruction were more likely to require surgery (90.0% vs. 53.9%, p = 0.09). The median follow-up duration was 24 months.ConclusionsIn this review of the literature, there were no significant differences in overall post-operative complications or scoliosis development by reconstruction method, yet complications after rigid reconstruction were more likely to require surgical intervention.Level of evidenceLevel IV.     

Ministernotomy compared with right anterior minithoracotomy for aortic valve surgery

ObjectivesMinisternotomy and right anterior minithoracotomy are the 2 main techniques applied for minimally invasive aortic valve replacement. The goal of this study is to compare early and long-term outcomes of both techniques.MethodsThe data of 2419 patients undergoing isolated minimally invasive aortic valve replacement between 1999 and 2019 were prospectively collected. Retrospectively, patients were divided into the ministernotomy group (n = 1352) and the minithoracotomy group (n = 1067).ResultsAfter propensity score matching, 986 patients remained in each group. Operation time and rate of conversion to full sternotomy were significantly higher in the minithoracotomy group than in the ministernotomy group (184.6 ± 45.2 vs 241.3 ± 68.6, relative risk, 2.54, P = .005 and .09 vs .23, relative risk, 1.45, P = .013, respectively). The 30-day mortality, excluding cardiac death, was lower in the ministernotomy group than in the minithoracotomy group (0.012 vs 0.028, relative risk, 1.41, P = .011, respectively); the intensive care unit length of stay (12.4 vs 16.5, relative risk, 1.62, P = .037, respectively) and hospital length of stay (5.4 vs 8.7, relative risk, 1.74 P = .028, respectively) were significantly longer in the minithoracotomy group. The minithoracotomy surgical approach was the strongest independent predictor of early mortality (odds ratio, 4.24 [1.67-7.35], P = .002). The actuarial survival by Kaplan–Meier analysis at 1, 3, 5, 10, and 20 years was significantly better in the ministernotomy group than in the minithoracotomy group (P = .0001). Actuarial freedom from reoperation at 5 years was 97.3% ± 4.4% in the ministernotomy group versus 95.8% ± 5.2% in the minithoracotomy group (P = .087).ConclusionsMinimally invasive aortic valve replacement using ministernotomy is associated with reduced operative time, intensive care unit stay, hospital length of stay, and postoperative morbidities and incisional pain, and improves early and long-term mortality.     

Contemporary treatment of keloids: A 10-year institutional experience with medical management,surgical excision,and radiation therapy

IntroductionWe evaluate a single center’s, decade-long experience utilizing 3 approaches to keloid treatment: corticosteroid medical management (MM), surgical excision (SE), and surgical excision + radiation therapy (SE + RT).Study designPatients undergoing keloid treatment were identified (2008–2017). Outcomes were symptomatology/cosmesis for MM, and recurrence and complications for SE and SE + RT. Logistic regression was used to determine factors associated with recurrence and complications.Results284 keloids (95 MM, 94 SE, 95 S E + RT) corresponded to patients with a median age of 39.1 (IQR: 26.1–53), 68.1% Black, and followed-up for 15.4 months (IQR: 5.6–30.7). For MM, 84.6% and 72.5% reported improvement in cosmesis and symptoms, respectively. SE and SE + RT recurrence were 37.2 and 37.9%, respectively. In adjusted analyses, higher radiation doses were associated with decreased recurrence whereas male gender (OR 3.3) and postoperative steroids (OR 9.5) were associated with increased recurrence (p < 0.01). There were more complications in the SE + RT group.ConclusionsMM resulted in at least some improvement. Recurrence rates after SE and SE + RT were similar. Female sex is protective, race does not affect outcomes.     

Asymptomatic degenerative mitral regurgitation repair: Validating guidelines for early intervention

IntroductionMitral repair for asymptomatic (New York Heart Association [NYHA] class I) degenerative mitral regurgitation (MR) is supported by the guidelines, but is not performed often. We sought to determine outcomes for asymptomatic patients when compared with those with symptoms.MethodsBetween 2004 and 2018, 1027 patients underwent mitral replacement (22) or repair with or without other cardiac surgery (1005), the latter being grouped by NYHA class: I (n = 470; 47%), II (n = 408; 40%), or III/IV (n = 127; 13%). Statistical analyses included propensity score matching and weighting, and multistate models.ResultsThe proportion of patients designated as NYHA class I undergoing surgery increased steadily during this period (P < .001). Overall, 30-day mortality was 0.4%, and zero for patients designated NYHA class I. Unadjusted 10-year survival was significantly greater in patients designated NYHA class I compared with II and III/IV (P < .001). Freedom from reoperation at 10 years was 99.8% overall, and 100% for patients designated NYHA class I. In patients designated as NYHA class I, predischarge and 10-year moderate MR were 0.7% and 20.1%, whereas more than moderate was zero and 0.6%. Preoperative ejection fraction less than 60% was associated with late mortality (P = .025). After covariate-adjustments, freedom from MR and tricuspid regurgitation were not statistically significantly different by NYHA class. However, overall survival was significantly worse in patients with NYHA class III/IV, compared with class II.ConclusionsMitral repair in asymptomatic patients is safe and durable. Careful monitoring until class II symptoms is appropriate. However, repair before ejection fraction decreases below 60% is important for late overall survival.
