Incidence and management of pleural effusions in patients with Wilms tumor: A Pediatric Surgical Oncology Research Collaborative study.

Wilms tumor (WT) is the most common renal malignancy in children. Children with favorable histology WT achieve survival rates of over 90%. Twelve percent of patients present with metastatic disease, most commonly to the lungs. The presence of a pleural effusion at the time of diagnosis of WT may be noted on staging imaging; however, minimal data exist regarding the significance and prognostic importance of this finding. The objectives of our study are to identify the incidence of pleural effusions in patients with WT, and to determine the potential impact on oncologic outcomes. A multi-institutional retrospective review was performed from January 2009 to December 2019, including children with WT and a pleural effusion on diagnostic imaging treated at Pediatric Surgical Oncology Research Collaborative (PSORC) participating institutions. Of 1259 children with a new WT diagnosis, 94 (7.5%) had a pleural effusion. Patients with a pleural effusion were older than those without (median 4.3 vs 3.5 years; P = .004), and advanced stages were more common (local stage III 85.9% vs 51.9%; P < .0001). Only 14 patients underwent a thoracentesis for fluid evaluation; 3 had cytopathologic evidence of malignant cells. Event-free and overall survival of all children with WT and pleural effusions was 86.2% and 91.5%, respectively. The rate and significance of malignant cells present in pleural fluid is unknown due to low incidence of cytopathologic analysis in our cohort; therefore, the presence of an effusion does not appear to necessitate a change in therapy. Excellent survival can be expected with current stage-specific treatment regimens.

Laparoscopic liver resection for hepatocellular carcinoma presents less respiratory complications compared with open procedure: A propensity score analysis in the elderly.

BACKGROUND: Resection is still the most efficacious treatment to hepatocellular carcinoma (HCC), among which laparoscopic liver resection (LLR) have controversial effects against conventional open procedure (OLR). With a predictable aging tendency of population worldwide, conventional surgical procedures need to be modified to better accommodate elderly patients. Here, we designed a retrospective study based on propensity score analysis, aiming to compare the efficacy of OLR and LLR in patients over 65 years. METHODS: We retrospectively analyzed patients with an age over 65 who underwent liver resection between January 2015 and September 2018. Patients were divided into the LLR group and OLR group. Short-term and long-term outcomes were compared before and after 1:1 propensity score matching. RESULTS: Among 240 enrolled patients, 142 were matched with comparable baseline (71 each group). In the matched cohort, LLR group presented with shorter postoperative hospital stay (median 7 vs 6 days, p = 0.003) and fewer respiratory complications (19.7% vs. 7.0%, p = 0.049), especially pleural effusion (15.5% vs. 2.8%, p = 0.020). Meanwhile, LLR had comparable overall hospital cost (6142 vs. 6243 USD, p = 0.977) compared with OLR. The overall survival (OS) and disease-free survival (DFS) did not differ in the two groups. CONCLUSIONS: Our study showed that laparoscopic liver resection for HCC in the older age groups is associated with shorter postoperative hospital stay and comparable hospital cost compared with open procedure, which could be attributable to less respiratory complications. We recommend that laparoscopy be taken as a priority option for elderly patients with resectable HCC.

Lung ultrasound in the monitoring of COVID-19 infection.

INTRODUCTION: Coronavirus disease 2019 (COVID-19) is a highly contagious illness caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Pneumonia and acute respiratory distress syndrome (ARDS) are the most common severe complications. There is growing evidence regarding the imaging findings of COVID-19 in chest X-rays and computed tomography (CT); however, their availability to clinical staff in this pandemic outbreak might be compromised. At this moment, the role of lung ultrasound (LUS) has yet to be explored. The purpose of this case report is to describe the natural course of the disease in mild infection managed at home. CASE REPORT: We report a 35-year-old man with recently diagnosed COVID-19 infection. Clinical examination was unremarkable. The diagnosis of mild disease was made clinically which was later reaffirmed by LUS after identifying a bilateral small pleural effusion and a thickened pleural line. During follow up, subpleural consolidations appeared before symptoms slightly aggravated (cough, tiredness and fever). The patient's condition improved after adjustment of therapy at home. CONCLUSION: LUS is an excellent tool in the characterisation of COVID-19 infection and is more available than CT or X-ray. We emphasise the utility and the opportunity that LUS presents in some clinical scenarios, like this COVID-19 pandemic, and how it may serve as a monitoring and therapy guide.

Diagnostic Utility and Impact on Clinical Decision Making of Focused Assessment With Sonography for HIV-Associated Tuberculosis in Malawi: A Prospective Cohort Study.

BACKGROUND: The focused assessment with sonography for HIV-associated tuberculosis (TB) (FASH) ultrasound protocol has been increasingly used to help clinicians diagnose TB. We sought to quantify the diagnostic utility of FASH for TB among individuals with HIV in Malawi. METHODS: Between March 2016 and August 2017, 210 adults with HIV who had 2 or more signs and symptoms that were concerning for TB (fever, cough, night sweats, weight loss) were enrolled from a public HIV clinic in Lilongwe, Malawi. The treating clinicians conducted a history, physical exam, FASH protocol, and additional TB evaluation (laboratory diagnostics and chest radiography) on all participants. The clinician made a final treatment decision based on all available information. At the 6-month follow-up visit, we categorized participants based on clinical outcomes and diagnostic tests as having probable/confirmed TB or unlikely TB; association of FASH with probable/confirmed TB was calculated using Fisher's exact tests. The impact of FASH on empiric TB treatment was determined by asking the clinicians prospectively about whether they would start treatment at 2 time points in the baseline visit: (1) after the initial history and physical exam; and (2) after history, physical exam, and FASH protocol. RESULTS: A total of 181 participants underwent final analysis, of whom 56 were categorized as probable/confirmed TB and 125 were categorized as unlikely TB. The FASH protocol was positive in 71% (40/56) of participants with probable/confirmed TB compared to 24% (30/125) of participants with unlikely TB (odds ratio=7.9, 95% confidence interval=3.9,16.1; P<.001). Among those classified as confirmed/probable TB, FASH increased the likelihood of empiric TB treatment before obtaining any other diagnostic studies from 9% (5/56) to 46% (26/56) at the point-of-care. For those classified as unlikely TB, FASH increased the likelihood of empiric treatment from 2% to 4%. CONCLUSION: In the setting of HIV coinfection in Malawi, FASH can be a helpful tool that augments the clinician's ability to make a timely diagnosis of TB.

Assessment of related surgical complications of minimally invasive retropleural approach to the thoraco-lumbar spine. / Evaluación crítica de las complicaciones asociadas al abordaje retropleural mínimamente invasivo en cirugía de columna toracolumbar.

OBJECTIVE: To review the complications associated with the minimally invasive retropleural approach used in the anterior approach to the thoraco-lumbar spine. MATERIAL AND METHOD: We present the MIS surgical technique and the evaluation of data collected prospectively from the initial series of 31 patients undergoing surgery. Pleural opening during the approach, lung complications derived, other surgical complications, time of intervention, intraoperative bleeding, need for transfusion and hospital stay are evaluated. DISCUSSION: The mean age of the patients was 58years, the surgical time 225min, and the bleeding 274ml, with a 13% postoperative transfusion. Intraoperatively, pleural opening was detected in 8 cases, of which none had major pulmonary complications during the postoperative period. There were 3 cases of mild pleural effusion, all patients without pleural opening, and one case of haemopneumothorax due to intercostal vessel bleeding that required reoperation. The percentage of intercostal neuralgia was 3%. The mean hospital stay was 6.7days, and 24 of 31 patients were able to initiate early mobilization on the first postoperative day. CONCLUSIONS: The retropleural approach allows the surgical treatment of pathologies requiring anterior access to the thoraco-lumbar spine, with a low profile of pulmonary complications, and with the advantages of minimally invasive techniques in terms of less bleeding, early recovery and shorter hospital stay. Nevertheless the learning curve is long.

Coronary artery bypass graft readmission rates and risk factors - A retrospective cohort study.

BACKGROUND: Hospital readmissions contribute substantially to the overall healthcare cost. Coronary artery bypass graft (CABG) is of particular interest due to its relatively high short-term readmission rates and mean hospital charges. METHODS: A retrospective review was performed on 2007-2011 data from California, Florida, and New York from the State Inpatient Databases, Healthcare Cost and Utilization Project. All patients ≥18 years of age who underwent isolated CABG and met inclusion/exclusion criteria were included. Insurance status was categorized by Medicaid, Medicare, Private Insurance, Uninsured, and Other. Primary outcomes were unadjusted rates and adjusted odds of readmission at 30- and 90-days. Secondary outcomes included diagnosis at readmission. RESULTS: A total of 177,229 were included in the analyses after assessing for exclusion criteria. Overall 30-day readmission rate was 16.1%; rates were highest within Medicare (18.4%) and Medicaid (20.2%) groups and lowest in the private insurance group (11.7%; p < 0.0001). Similarly, 90-day rates were highest in Medicare (27.3%) and Medicaid (29.8%) groups and lowest in the private insurance group (17.6%), with an overall 90-day rate of 24.0% (p < 0.0001). The most common 30-day readmission diagnoses were atrial fibrillation (26.7%), pleural effusion (22.5%), and wound infection (17.7%). Medicare patients had the highest proportion of readmissions with atrial fibrillation (31.7%) and pleural effusions (23.3%), while Medicaid patients had the highest proportion of readmissions with wound infections (21.8%). Similar results were found at 90 days. Risk factors for readmission included non-private insurance, age, female sex, non-white race, low median household income, non-routine discharge, length of stay, and certain comorbidities and complications. CONCLUSIONS: CABG readmission rates remain high and are associated with insurance status and racial and socioeconomic markers. Further investigation is necessary to better delineate the underlying factors that relate racial and socioeconomic disparities to CABG readmissions. Understanding these factors will be key to improving healthcare outcomes and expenditure.

Pleural drainage using drainage bag for thoracoscopic lobectomy.

Objective This study was designed to compare the effectiveness and convenience of a drainage bag and a chest bottle following thoracoscopic lobectomy. Methods We conducted a test to ensure that the drainage bag was characterized by easy drainage and an antireflux effect. Thereafter, the drainage bag was used in all thoracic operations in our service. To understand the usefulness of the drainage bag, a retrospective cohort study enrolled 30 patients who had a drainage bag after thoracoscopic lobectomy and compared them with 30 similar patients operated on previously who had chest bottles. Variables studied included total drainage volume, duration of drainage, complications, and satisfaction of the care providers. Results There was no significant difference between the chest bottle and drainage bag groups respectively in terms of total drainage (697.5 ± 89.7 vs. 614.1 ± 76.6 mL, p = 0.483) or duration of drainage (4.23 ± 0.38 vs. 4.43 ± 0.38 days, p = 0.713). No device-related complication was observed. After our experience with the drainage bag, we abandoned use of the chest bottle. The drainage bag was more convenient for patients and promoted early ambulation as well improving cost effectiveness. Most care providers preferred to use the drainage bag (p = 0.000). Conclusion The drainage bag is superior to the chest bottle for postoperative drainage.

Assessment of a bedside test for N-terminal pro B-type natriuretic peptide (NT-proBNP) to differentiate cardiac from non-cardiac causes of pleural effusion in cats.

BACKGROUND: Cats with pleural effusion represent common emergencies in small animal practice. The aim of this prospective study was to investigate the diagnostic ability of a point-of-care ELISA (POC-ELISA) for the measurement of N-terminal pro B-type natriuretic peptide (NT-proBNP) to differentiate cardiac from non-cardiac disease in cats with pleural effusion. The sample material for use of this rapid test was either plasma or diluted pleural effusion. Twenty cats with moderate to severe pleural effusion were prospectively recruited. The cats were grouped into two groups, with or without congestive heart failure (CHF; N-CHF), after complete work-up. Blood and effusion were collected in EDTA tubes. Plasma and pleural effusion supernatants were transferred into stabilizer tubes and frozen. POC-ELISA for NT-proBNP was performed with plasma and diluted effusion (1:1). Quantitative NT-proBNP measurement was performed in plasma and diluted and undiluted effusions. RESULTS: Six cats were assigned to the CHF group. Of the 14 cats in the N-CHF group, 6 had concurrent cardiac abnormalities that were not responsible for the effusion. For the detection of CHF, the test displayed respective sensitivities and specificities of 100% and 79% in plasma and 100% and 86% in diluted pleural fluid. Receiver operating characteristic (ROC) analysis for quantitative NT-proBNP measurement of plasma and diluted and undiluted pleural effusions displayed areas under the curve of 0.98, sensitivities of 100% and specificities of 86%. The optimum cut-off was calculated at 399 pmol/l in plasma and 229 pmol/l in the diluted effusion and 467 pmol/l in the undiluted effusion. CONCLUSIONS: POC-ELISA for NT-proBNP in both plasma and diluted pleural effusion was suitable to differentiate cardiac from non-cardiac causes of feline pleural effusion. According to our results, use of pleural effusion is feasible, but dilution of the effusion before measurement seems to improve specificity.

Lung ultrasound as a translational approach for non-invasive assessment of heart failure with reduced or preserved ejection fraction in mice.

AIMS: Heart failure (HF) has become an epidemic and constitutes a major medical, social, and economic problem worldwide. Despite advances in medical treatment, HF prognosis remains poor. The development of efficient therapies is hampered by the lack of appropriate animal models in which HF can be reliably determined, particularly in mice. The development of HF in mice is often assumed based on the presence of cardiac dysfunction, but HF itself is seldom proved. Lung ultrasound (LUS) has become a helpful tool for lung congestion assessment in patients at all stages of HF. We aimed to apply this non-invasive imaging tool to evaluate HF in mouse models of both systolic and diastolic dysfunction. METHODS AND RESULTS: We used LUS to study HF in a mouse model of systolic dysfunction, dilated cardiomyopathy, and in a mouse model of diastolic dysfunction, diabetic cardiomyopathy. LUS proved to be a reliable and reproducible tool to detect pulmonary congestion in mice. The combination of LUS and echocardiography allowed discriminating those mice that develop HF from those that do not, even in the presence of evident cardiac dysfunction. The study showed that LUS can be used to identify the onset of HF decompensation and to evaluate the efficacy of therapies for this syndrome. CONCLUSIONS: This novel approach in mouse models of cardiac disease enables for the first time to adequately diagnose HF non-invasively in mice with preserved or reduced ejection fraction, and will pave the way to a better understanding of HF and to the development of new therapeutic approaches.

Chest radiograph after fluoroscopic guided line placement: No longer necessary.

PURPOSE: Historically, a chest radiograph was obtained after central line placement in the operating room. Recent retrospective studies have questioned the need for this radiograph. The prevailing current practice at our center is to order chest radiograph only for symptomatic patients. This study examines the outcomes of selective chest radiography after fluoroscopic guided central line placement. METHODS: After obtaining institutional review board approval, a single institution retrospective chart review of patients undergoing central venous catheter placement by the pediatric surgery or interventional radiology service between January 2010 and July 2014 was performed. Outcome measures included CXR within 24h of catheter placement, reason for chest radiograph, complication, and complication requiring intervention. RESULTS: In the study population 622 catheters were placed under fluoroscopy. A chest radiograph was performed in 118 (19%) patients within 24h of the line placement with 25 (4%) of these patients being symptomatic in the recovery room. One patient required chest tube for shortness of breath and pleural effusion. Four symptomatic patients (0.6%) were found to have a pneumothorax, none of which required chest tube placement. There were no re-operations because of mal-position of the catheter. In the 504 patients with no postoperative chest x-ray, there were no adverse outcomes. At our institution the current average charge of a chest radiograph is $283, thus we produced savings of $142,632 for the study period without adverse events. CONCLUSION: After placement of central venous catheter under fluoroscopic guidance, a chest radiograph is unlikely to be helpful in an asymptomatic patient.

Assessment of the Impact of Skeletonization on Pleuropulmonary Changes after Bilateral Internal Thoracic Artery Harvest for Coronary Artery Bypass Grafting.

BACKGROUND AND AIMS: Skeletonization has been proposed as a technique to minimize the risk of sternal devascularization during bilateral internal thoracic artery harvest for coronary artery bypass grafting. The impact of this strategy on late radiologic pleuropulmonary changes has not been addressed. MATERIAL AND METHODS: Post-operative chest radiographs from patients (n = 253 per group) undergoing bilateral internal thoracic artery harvest using skeletonized and non-skeletonized techniques were reviewed by blinded radiologists. The primary outcome was the incidence of atelectasis and pleural effusion. Multivariable linear regression models were derived to assess the relationship of radiologic pleuropulmonary outcomes to patients and operative variables. RESULTS AND CONCLUSION: Patients in the skeletonized group were older (p < 0.0001), had a lower preoperative hematocrit (p = 0.014), had higher prevalence of peripheral vascular disease (p = 0.001), were of female gender (p = 0.015), underwent off-pump surgery (p < 0.001), had urgent/emergent status (p = 0.024), and had chronic obstructive pulmonary disease (p = 0.019). There was no difference in the incidence of post-operative complications, ventilation time, or intensive care unit stay. There was no difference in the severity of post-operative atelectasis in both groups. More patients in the non-skeletonized group had a grade 2/3 left pleural effusion on the late post-operative chest X-ray (p = 0.007). The independent effect of skeletonization on the development of a late left pleural effusion was significant (odds ratio = 0.558, 95% confidence interval = 0.359-0.866, p = 0.009). Skeletonization results in a decreased incidence of late post-operative left pleural effusion with no difference in early or late atelectasis. Further studies are warranted to assess the mechanism of these pleuropulmonary changes and the impact of other factors such as pleural violation during surgery.

Reduced pleural drainage, length of stay, and readmissions using a modified Fontan management protocol.

BACKGROUND: Persistent pleural effusions after the Fontan procedure contribute to prolonged hospitalization and increased costs. We report our experience using a modified Wisconsin Fontan protocol to reduce chest tube drainage and hospital length of stay (LOS). METHODS: Single institutional retrospective chart review of 120 consecutive patients (60 before and 60 after initiation of our protocol) undergoing an extracardiac Fontan procedure from January 2004 to February 2007. Protocol influence was assessed by comparing group differences on duration of pleural drainage, requirement for nothing by mouth/total parenteral nutrition, hospital LOS, readmission for pleural effusion, and total hospital costs. RESULTS: Groups were similar in demographic characteristics, single ventricle morphology, preoperative hemodynamic parameters, and operative and immediate postoperative management. Median duration of pleural drainage and hospital LOS was reduced in the post- versus preprotocol groups: 4 days (interquartile range [IQR], 4-5 days) pre versus 6 days (IQR, 5-10 days) (P < .0001) and 6 days (IQR, 5-9 days) versus 8 days (IQR, 6-13 days) (P = .005), respectively. Pleural drainage lasting >1 week was also less common postprotocol: 23 (38%) before versus 7 (12%) after (P = .001). Fewer postprotocol patients required nothing by mouth/total parenteral nutrition to control effusions: 5 pre versus 0 post (P = .06), and fewer readmissions for effusions (14 before vs 7 after [P = .1]). An average total cost savings of 22% and readmissions savings of 29% resulted in nearly $500,000 in institutional savings over the study period. CONCLUSIONS: A modified Fontan protocol resulted in reduced time to chest tube removal, hospital LOS, and chest tube drainage lasting >1 week. There was a strong trend toward avoiding nothing by mouth/total parenteral nutrition to control pleural effusion and lower hospital costs.

Assessment of a panel of tumor markers for the differential diagnosis of benign and malignant effusions by well-based reverse phase protein array.

BACKGROUND: The differential diagnosis of benign and malignant effusion is often hampered by low cell content or insufficiently preserved tumor cells. In this study, we evaluated the combined diagnostic value of six tumor markers measured by well-based reverse-phase protein array (RPPA) for diagnosis of malignant effusion. METHODS: A total of 114 patients (46 with malignant effusions, 32 with probable malignant effusions, and 36 with benign effusions) were enrolled. Expressional levels of MUC1, EMA, Pan-CK, HSP90, TGF-ß and CA125 were determined by well-based RPPA. RESULTS: Median relative expression of MUC1, Pan-CK and EMA were significantly higher in malignant effusion than those in probable malignant or benign (p < 0.001, p = 0.003, p < 0.001, respectively), whereas the level of TGF-ß in malignant effusions were significantly lower than that in the other groups (p = 0.005). For predicting malignancy, EMA presented the best areas under the curve of 0.728 followed by MUC1 of 0.701. The sensitivity of 52.0% for MUC1 and 48.0% for EMA were not better than cytology. However, sensitivity, negative predictive value, and accuracy of the tumor marker panel were better than cytology by 14.7%, 7.5%, and 6.1%, respectively. CONCLUSIONS: Tumor marker panel measured by well-based RPPA showed values in the differential diagnosis between benign and malignant effusions. Further large scale studies need to be performed to evaluate the utility of this panel of markers.

[Pleural effusion cytology of asbestos-associated malignant mesothelioma and lung carcinoma in the diagnosis of occupational diseases by the statutory accident insurance funds]. / Zytopathologische Ergussdiagnostik in der berufsgenossenschaftlichen Begutachtung von Asbest-assoziierten malignen Mesotheliomen und Lungenkarzinomen.

Pleural effusion often represents the first clinical symptom of lung carcinoma and malignant mesothelioma. As pleural punctation is performed quite early in the diagnostic procedure, effusion cytology frequently gives the first evidence about the presence of tumour cells and tumor histogenesis. In this study, we report on seven cases which were evaluated in our institution for the Employers' Liability Insurance Association, based solely on cytology findings.The mean age of the seven patients with a given long-term asbestos exposure during their working life was 81.7 years. On average eight smears per patient were investigated. In addition to routine cytology, immunocytochemistry, DNA image cytometry, AgNOR-analysis and fluorescence in situ hybridization were applied in a case-specific way. The results were interpreted against the clinical and occupational history of the respective patient.Definitive diagnosis could be made in six cases. In three of them, the diagnosis of malignant mesothelioma was made. Two cases were diagnosed as malignant effusion due to metastatic lung cancer. In one case, cells of high-grade Non-Hodgkin's lymphoma (NHL) were diagnosed and a malignant mesothelioma was excluded. In the last case, malignant mesothelioma could not be diagnosed unequivocally by cytology. In all seven cases, our interpretation was accepted by Employers' Liability Insurance Association. The five mesothelioma or lung cancer cases were accepted as asbestos-associated occupational disease, while the NHL case was rejected. In the last case, malignant mesothelioma was diagnosed later by autopsy, and the case was retroactively accepted as occupational disease.Cytology-based tumor diagnosis including adjuvant methods is a useful and reliable approach in cases of asbestos-associated tumours. Acceptance of occupational disease on the basis of cytological diagnoses even by the Employers' Liability Insurance Association helps avoid invasive pleural or lung biopsies in cases with an unequivocally positive effusion cytology of lung cancer or malignant mesothelioma.

Assessment of intraoperative tube thoracostomy after diaphragmatic resection as part of debulking surgery for primary advanced-stage Müllerian cancer.

OBJECTIVE: The present study assessed the use of an intraoperative tube thoracostomy for patients with primary advanced-stage ovarian, fallopian tube, or peritoneal cancer who underwent a diaphragmatic resection as part of debulking surgery and to define which patients are more likely to benefit from an intraoperative tube thoracostomy. METHODS: All consecutive patients with stage IIIC-IV Müllerian cancer who underwent diaphragmatic resection at our institution between April 2008 and March 2013 were retrospectively reviewed. When a full-thickness resection of the diaphragm was performed and the thoracic cavity was opened, a chest tube was routinely placed during surgery. Patient-, disease-, and surgery-related data were collected from the patients' medical records. The data were evaluated with particular attention directed at pleural effusion after diaphragmatic resection. RESULTS: A total of 37 patients were included in this study. No complications associated with the intraoperative tube thoracostomy procedures occurred. An infection of the thoracic cavity occurred in one patient, following the presence of intra-abdominal abscess. The total volume of pleural drainage ranged from 88 to 2826 mL (median, 965 mL). The estimated blood loss, intraoperative blood transfusion, and area of the diaphragmatic opening were significantly associated with the total volume of pleural drainage in univariate analyses. In a multivariate analysis, the estimated blood loss was the only factor to be significantly associated with the total volume of pleural drainage. CONCLUSIONS: A prophylactic tube thoracostomy might be considered if the volume of the estimated blood loss is higher than usual.

Patient, treatment and discharge factors associated with hospital readmission within 30 days after surgical cytoreduction for epithelial ovarian carcinoma.

OBJECTIVE: Hospital readmissions are common, costly and increasingly viewed as adverse events. In gynecologic oncology, data on readmissions are limited. The goal of this study was to examine the patient, treatment and discharge factors associated with unplanned readmission after cytoreductive surgery. METHODS: We identified all patients with stages II-IV ovarian cancer who underwent surgical cytoreduction at our institution between 2003 and 2011. A retrospective chart review was performed, and clinical variables were extracted. Utilizing linear and logistic regression, these clinical variables were correlated with risk of readmission. RESULTS: A total of 460 patients were included in the analysis, with the majority having a stage IIIC high grade serous cancer. Optimal cytoreduction (<1.0 cm residual disease) was obtained in 368 patients (81%), and 233 patients (50%) underwent at least one radical procedure. Perioperative complications were observed in 148 patients (32%). A large proportion of our cohort was discharged to rehabilitation facilities (12%) or with a visiting nurse (38%). Fifty five patients (12%) were readmitted within 30 days. On multivariate logistic regression, reoperation and perioperative cardiopulmonary event were the only factors associated with readmission (OR=3.2, 95% CI=1.7-6.0). Discharge home with ancillary services was not protective against readmission, even when controlling for perioperative complications (OR=1.18, 95% CI=0.53-2.64). CONCLUSIONS: Readmission after surgical cytoreduction affected 12% of our population. Multivariate analyses suggested perioperative complications, particularly reoperation and cardiopulmonary event, placed the patient at the greatest risk. Age, comorbidities, surgical radicality and discharge with visiting nurse services/rehabilitation facility did not affect the likelihood of readmission.

An approach to the assessment and management of the laparoscopic adjustable gastric band patient in the emergency department.

OBJECTIVE: As the number of obese people in Australia continues to increase, laparoscopic adjustable gastric banding (LAGB) surgery will become increasingly common. It is important for practitioners involved in the care of such patients to be able to accurately diagnose, and initially manage, pathology relating to the LAGB. METHODS: A retrospective review of 56 presentations in 41 patients with LAGB, who presented to the ED of a major tertiary hospital, was performed. Note was made of presenting symptoms, investigations undertaken, subsequent diagnosis, and initial and definitive management. RESULTS AND DISCUSSION: The commonest presenting symptoms included abdominal pain, nausea, vomiting and dysphagia. The ultimate diagnosis was food bolus obstruction (18 presentations; 32.1%), port infection (11 presentations; 19.6%), band prolapse (9 presentations; 16.1%), band erosion (2 presentations; 3.6%) and subacute bowel obstruction (1 presentation; 1.8%). Food bolus obstruction was best diagnosed clinically. Plain abdominal X-ray was useful to identify prolapse. Infection was best diagnosed with the combination of clinical picture and wound swab. CT scan was helpful when suspecting a deep source of infection. From these data, two algorithms were developed, which can be used as a clinical aide to help practitioners in diagnosing and treating such complications appropriately. CONCLUSION: It is important that health-care professionals are aware of the common presentations of problems following LAGB and have a basic paradigm for initial care. The present study identifies the presenting picture of various complications that can arise postoperatively, and describes an approach to the assessment and management of the LAGB patient in the ED.

Management of complications following aesthetic procedures can lead to significant additional cost.

Liposuction is one of the most common surgical interventions in aesthetic surgery, technically easy to perform and is also carried out by many non-plastic surgeons. However, this operation can have severe complications, and dealing with them can impose a great financial burden on the tax payer-supported national health-care systems. We report here about a patient, who was hospitalised for complications after a failed office-based liposuction. The ensuing costs of treatment are also discussed.

Efficacy of anterior fissureless technique for right upper lobectomies: a case-matched analysis.

OBJECTIVE: In pulmonary lobectomy, the dissection through the fissure to gain access to the pulmonary artery may increase the risk of postoperative air leak. For several anatomic reasons, this risk is especially high after right upper lobectomies (RULs). The objective of this investigation was to verify the efficacy of an anterior fissureless lobectomy (FL) technique in reducing the incidence and duration of air leak after RUL. METHODS: An observational analysis was performed of 206 consecutive patients (2002-2009) submitted to RUL for non-small-cell lung cancer. Operations were performed through a muscle-sparing lateral thoracotomy. Patients with completely developed fissures were excluded. No sealants or buttressing material were used. For group TR (traditional resection, 146 patients), RUL was performed by traditional intra-fissure dissection of the pulmonary artery; for group FL (60 patients), RUL was carried out by fissureless division of all hilar vascular structures. Several perioperative variables were used in identifying propensity score-matched pairs of patients undergoing traditional and fissureless lobectomies. The matched groups were then compared in terms of incidence of prolonged air leak, air leak duration, operation time, chest tubes duration, hospital stay and costs. RESULTS: Propensity score analysis yielded 58 well-matched pairs of patients operated by traditional or fissureless RUL. Compared to those in the traditional group, patients in group FL had a mean reduction in air leak duration, duration of chest tube and postoperative stay of 1.1, 1.4 and 1.2 days, respectively. This translated into an average hospital cost saving of 569 € per patient. CONCLUSIONS: The use of an anterior fissureless technique during RUL reduced the duration of air leak and hospital costs without increasing the surgical time. Given its simplicity and efficacy, we regard it as a useful tool for implementing fast-tracking policies and cutting hospital costs.

Assessment and management of patients with pleural effusion.

Pleural effusions are a common medical condition with a significant source of morbidity, and there are wide variations in management. Over the past 5 years there has been rapid advancement in the knowledge and treatment of pleural diseases and effusions. This article provides an overview of the anatomy and physiology of the pleural space and pleural membranes, and an update on assessment and management of patients with pleural effusions in line with new developments and related national guidelines.
