A Standardized Minimal Opioid Prescription Post-Thoracic Surgery Provides Adequate Pain Control.

BACKGROUND: Given the national opioid crisis, postoperative analgesia at discharge must be thoughtfully prescribed. Data specifically related to thoracic procedures remain scarce. This study assessed adequacy of pain control with standardized and limited opioids after thoracic procedures. METHODS: A standardized prescription comprised 15 hydromorphone tabs, 7 days of acetaminophen, and 3 days of ibuprofen was provided on discharge to elective thoracic surgery patients. On the first postoperative visit, patients completed a questionnaire regarding the number of hydromorphones used, use of additional opioids, pain-related limitation to function, and adequacy of pain control. RESULTS: A total of 122 patients undergoing thoracic surgery procedures were surveyed. Twelve underwent open procedures and were excluded. An additional 6 patients who used opioids chronically preoperatively were also excluded. The remaining 104 patients were included in the study. Median age was 66 years (age range, 17-90 years) and median length of stay was 2 days (range, 1-15 days). Seventeen (16%) patients used all prescribed hydromorphone and 56 (54%) used none, 18 (17%) asked for additional or other opioid, and 14 (13%) felt that their pain significantly limited their function. Nine (9%) felt that that their pain was inadequately controlled. CONCLUSIONS: Pain after thoracic procedures, especially video-assisted thoracoscopic surgery, is adequately controlled with minimal opioid doses (combined with adjuncts), with less than 1 in 5 patients requiring additional prescriptions and very few patients complaining of pain that significantly limited their function. This study shows that a standardized limited opioid prescription is safe, is adequate, and can easily be implemented for the majority of thoracic surgery patients.

Video-assisted thoracoscopic resection of a giant esophageal schwannoma: A case report.

INTRODUCTION AND IMPORTANCE: Intrathoracic schwannomas are rare and difficult to diagnose. However, they are the most common type of neurogenic tumor in the chest. Most patients are incidentally diagnosed or develop symptoms from mass effect, such as chest pain, dysphagia or dyspnea. Larger tumors have been resected using open approaches, while smaller ones are often excised with minimally invasive approaches. CASE PRESENTATION: A 60-year-old woman with a prior Roux-en-Y gastric bypass and a history of dysphagia, decreased appetite, and weight loss was referred for evaluation. CT chest revealed an 8 cm soft tissue mass centered in the distal esophagus. Gastroscopy showed the tumor to be 8 cm as well, with 2 cm of normal esophagus prior to the gastric pouch. A right-sided video-assisted thoracoscopic (VATS) approach for enucleation was successfully completed with primary esophageal repair for an 8.0 × 5.5 × 6.5 cm schwannoma. CLINICAL DISCUSSION: Surgical resection for schwannomas is often indicated due to symptoms from mass effect (Moro et al., 2017). There are reports of VATS and robotic-assisted thoracic surgery approaches for small tumors. These techniques are appealing due to shorter length of stays and less post-operative pain. None have been described for lesions larger than 6 cm. CONCLUSION: Minimally invasive approaches such as VATS for large schwannomas are technically feasible and safe to perform without the need for a thoracotomy.

Hypertension in pregnancy: An unresectable mediastinal pheochromocytoma.

Hypertension is a relatively common occurrence during pregnancy, which usually has a benign course with an excellent prognosis. However, physicians caring for pregnant women should have a high index of suspicion for underlying medical conditions that could lead to a more perilous outcome. Herein, we present the case of a pregnant woman who was found to have uncontrollable hypertension late in her pregnancy, secondary to a mediastinal pheochromocytoma, which was deemed unresectable at the time of exploration after her delivery.

Self-Reported Outcomes in Individuals Aged 65 and Older Admitted for Treatment to an Acute Care Surgical Service: A 6-Month Prospective Cohort Study.

OBJECTIVES: To examine health-related quality of life (HRQL) and cognitive and functional status before and after emergency surgical care in elderly adults. DESIGN: Six-month prospective cohort study. SETTING: Acute care and emergency surgery service at a single, academic tertiary care center, Edmonton, Alberta, Canada. PARTICIPANTS: Admitted individuals aged 65 and older (mean age 77.8 ± 7.9, 52% female) or their surrogates. MEASUREMENTS: Abbreviated Mental Test Score-4 (AMTS), Barthel Index, Vulnerable Elders Survey (VES-13), and EuroQol-5 Dimensional Scale (EQ-5D) completed by participants or their surrogates within 24 hours of admission to the hospital and 6 months after discharge. Paired t-tests and McNemar tests were used to assess the difference between baseline and 6 months. RESULTS: One hundred fifty-five consecutive individuals (including 16 surrogates) were enrolled. Sixteen (10%) died within 6 months of discharge, and 116 (75%, including 18 surrogates) completed a follow-up assessment 6 months after discharge. Cognitive status improved substantially over 6 months, with 72 (52%) of participants having AMTS scores showing cognitive impairment at baseline and four (4%) having AMTS scores showing cognitive impairment at 6 months (P < .001). There was no statistically significant change from baseline on the Barthel Index, VES-13, or EQ-5D. CONCLUSION: There was significant cognitive improvement in older adults after surgical hospitalization. HRQL improved back to age-matched population norms. These results suggest that elderly adults admitted for emergency surgery have good cognitive, functional, and HRQL outcomes.

Non-small cell lung cancer detection using microRNA expression profiling of bronchoalveolar lavage fluid and sputum.

AIM: To assess if miRNA expression profiling of bronchoalveolar lavage (BAL) fluid and sputum could be used to detect early-stage non-small cell lung cancer (NSCLC). MATERIALS AND METHODS: Hierarchical cluster analysis was performed on the expression levels of 5 miRNAs (miR-21, miR-143, miR-155, miR-210, and miR-372) which were quantified using RNA reverse transcription and quantitative real-time polymerase chain reaction in sputum and BAL samples from NSCLC cases and cancer-free controls. RESULTS: Cluster analysis of the miRNA expression levels in BAL samples from 21 NSCLC cases and sputum samples from 10 cancer-free controls yielded a diagnostic sensitivity of 85.7% and specificity of 100%. Cluster analysis of sputum samples from the same patients yielded a diagnostic sensitivity of 67.8% and specificity of 90%. CONCLUSION: miRNA expression profiling of sputum and BAL fluids represent a potential means to detect early-stage NSCLC.

A Systematic Review and Meta-Analysis of Open vs. Laparoscopic Resection of Gastric Gastrointestinal Stromal Tumors.

Gastric gastrointestinal stromal tumors (GISTs) are the most common sarcoma of the gastrointestinal tract, and surgical resection is the primary treatment of early disease. Limited data exist concerning laparoscopic resections of these neoplasms. This systematic review was designed to evaluate the literature comparing laparoscopic and open surgical resection of gastric GISTs and to assess the effectiveness and safety of this minimally invasive technique. We performed a systematic search of MEDLINE, the Cochrane Library, PubMed, Embase, Scopus, Web of Science, Google Scholar, the clinical trials database and ProQuest Dissertations and Theses as well as the past 3 years of conference abstracts from the Society of American Gastrointestinal and Endoscopic Surgeons Annual Meetings. Studies comparing the open and the laparoscopic approaches to the resection of gastric GISTs were included in this systematic review. Two reviewers independently performed the screen of titles and abstracts, the full manuscript review, the data extraction and the risk of bias assessment. A quantitative analysis was performed. Of the 189 studies identified, seven studies were included. The laparoscopic approach was associated with a significantly lower length of hospital stay (3.82 days (2.14 - 5.49)). There was no observed difference in operative time, adverse events, estimated blood loss, overall survival and recurrence rates. This study supports that laparoscopic resection is safe and effective for gastric GISTs and is associated with a significantly lower length of hospital stay. Further trials are needed for cost analysis and to rigorously assess oncologic outcomes.

A systematic review and meta-analysis to assess patient-reported outcomes after lung cancer surgery.

The main objective of this review was to systematically review, assess, and report on the studies that have assessed health related quality of life (HRQOL) after VATS and thoracotomy for resection of lung cancer. We performed a systematic review of six databases. The Downs and Black tool was used to assess the risk of bias. Five studies were included. In general, patients undergoing VATS have a better HRQOL when compared to thoracotomy; however, there was a high risk of bias in the included studies. The consistent use of a lung cancer specific questionnaire for measuring HRQOL after surgery is encouraged.

Quality of life and long-term outcomes of octo- and nonagenarians following acute care surgery: a cross sectional study.

BACKGROUND: While advanced age is often associated with poorer surgical outcomes, long-term age-related health status following acute care surgery is unknown. The objective of our study was to assess post-operative cognitive impairment, functional status, and quality of life in elderly patients who underwent emergency surgery. METHODS: We identified 159 octo- and nonagenarians who underwent emergency surgery between 2008 and 2010 at a single tertiary hospital. Patients were grouped into three cohorts: 1, 2, and 3 years post-operative. We conducted a survey in 2011, with octo- and nonagenarians regarding the impact of emergency surgical procedures. Consenting participants responded to four survey questionnaires: (1) Abbreviated Mental Test Score-4, (2) Barthel Index, (3) Vulnerable Elders Survey, and (4) EuroQol-5 Dimensional Scale. RESULTS: Of the 159 octo- and nonagenarians, 88 (55.3%) patients were alive at the time of survey conduction, and 55 (62.5%) of the surviving patients consented to participate. At 1, 2, and 3 years post-surgery, mortality rates were 38.5%, 44.7%, and 50.0%, respectively. More patients had cognitive impairments at 3 years (33.3%) than at 1 (9.5%) and 2 years (9.1%) post-operatively. No statistical difference in the ability to carry out activities of daily living or functional decline with increasing time post-operatively. However, patients perceived a significant health decline with the greater time that passed following surgery. CONCLUSIONS: Our study showed that half of the patients over the age of 80 are surviving up to 3 years post-operatively. While post-operative functional status appears to be stable across the 3 cohorts of patients, perceived health status declines over time. Understanding the long-term post-operative impact on cognitive impairment, functional status, and quality of life in elderly patients who undergo acute care surgery allows health care professionals to predict their patients' likely post-operative needs.

Sputum microRNA profiling: a novel approach for the early detection of non-small cell lung cancer.

PURPOSE: MicroRNAs (miRNAs) post-transcriptionally regulate hundreds of gene targets involved in tumorigenesis thereby controlling vital biological processes, including cellular proliferation, differentiation and apoptosis. MiRNA profiling is an emerging tool for the potential early detection of a variety of malignancies. This study was conducyed to assess the feasibility and methodological robustness of quantifying sputum miRNAs, employing quantitative real-time polymerase chain reaction (RT-qPCR) and cluster analysis on an optimized miRNA profile as a novel approach for the early detection of non-small cell lung cancer (NSCLC). METHODS: The relative expressions of 11 miRNAs in sputum (miR-21, miR-145, miR-155, miR-205, miR-210, miR-92, miR-17-5p, miR-143, miR-182, miR-372, and let-7a) in addition to U6 were retrospectively assessed in four NSCLC-positive and four negative controls. Subsequently, a set of five miRNAs (miR-21, miR-143, miR-155, miR-210, miR-372) was selected because of degree of relatedness observed in the cluster analysis and tested in the same sputum sample set. The five optimized miRNAs accurately clustered these eight retrospective patients into NSCLC positive cases and negative controls. The five miRNA panel was then prospectively quantified in the sputum of 30 study patients (24 NSCLC cases and six negative controls) in a double-blind fashion to validate a five miRNA panel using hierarchical cluster analysis. RESULTS: The optimized five miRNA panel detected NSCLC (83.3% sensitivity and 100% specificity) in 30 prospectively accrued study patients. CONCLUSION: Sputum miRNA profiling using cluster analysis is a promising approach for the early detection of non-small cell lung cancer. Further investigation using this approach is warranted.

Diaphragmatic plication offers functional improvement in dyspnoea and better pulmonary function with low morbidity.

A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was as follows: In adults with unilateral diaphragmatic paralysis, does diaphragmatic plication offer functional improvement in dyspnoea, better pulmonary function tests (PFTs) and return to activity? A total of 126 papers were found using the reported search, of which 13 represented the best evidence to answer the clinical question. The authors, date and country of publication, patient group studied, surgical approach, study type, relevant outcomes and results of these articles are tabulated. Those articles reporting improvement in PFTs following plication, documented this benefit in the following parameters: mean forced vital capacity (range 17-40%), forced expiratory volume at 1 sec (range 21-27%), functional residual capacity (range 20-21%) and total lung capacity (range 16-19%). The percentage of postoperative improvement in shortness of breath as measured by a dyspnoea score was reported to be between 90 and 96% in the thoracotomy group and 100% in the Video Assisted Thoracoscopic Surgery (VATS) group, the dyspnoea score that was used in all the studies was a visual analogue scale between 0 and 10 where 0 is no dyspnoea and 10 is the worst dyspnoea a patient can have. One of the studies reported postoperative normalization in ventilation perfusion scan (VQ) scan parameters when compared with the preoperative mismatch. Complication rate was similar between the two groups, while the mortality rate was 4% in the thoracotomy group and 0% in the VATS group. The total number of patients included in all the studies combined was 161. All reports included in this review are observational studies (one cohort study and the remainder being case series); therefore, the risk of selection, information and publication biases are high and conclusions should be implemented with caution. We conclude that diaphragmatic plication can improve the functional status, shortness of breath and PFTs of patients with unilateral diaphragm paralysis. Patients undergoing a VATS approach appear to have more advantages in objective and subjective measures (including PFTs, dyspnoea score, length of hospital stay and postoperative complications). Further research with high-quality study designs is advised, focussing mainly on the long-term benefits and assessment of health-related quality of life.

Surgisis mesh for tracheal reconstruction.

Esophagectomy is a commonly performed procedure that has a high morbidity rate. Postesophagectomy anastomotic leaks are not uncommon; however fistulas to the airways remain a rare and often catastrophic complication. Although most fistulas occur from a direct communication between a failed anastomosis and an adjacent airway, other risk factors have been identified, such as tracheal ischemia from extensive mediastinal dissection, intraoperative tracheal injuries, and cuff necrosis from prolonged intubation. Despite advancements in the management of sepsis, leaks and fistulas are still associated with a high mortality rate and continue to challenge esophageal surgeons.

A method of assessing reasons for conversion during video-assisted thoracoscopic lobectomy.

Conversion rates during video-assisted thoracoscopic lobectomy are reported, but no previous publications have classified the cause of conversion. The aim of the study was to develop a quality assessment tool [vascular, anatomy, lymph node, technical (VALT) 'Open'] to evaluate reasons and nature of conversion during the development of a video-assisted thoracoscopic lobectomy program. Between 2006 and 2008, 237 patients with a median age of 65 years underwent video-assisted thoracoscopic lobectomy primarily for lung. The number of video-assisted thoracoscopic lobectomy cases over open cases has increased over the period. Conversion rate has dropped from 15% (2006) to 11% (2008). A total of 32 cases required conversion. The VALT 'Open' classification for reason to convert and nature of conversion was used. The average length of stay was shorter for non-converted cases. No uncontrolled conversions where the patient was unstable were required, and in the 14 cases converted following some difficulty, such as pulmonary artery injury. A pattern to the learning curve became predictable. The quality assessment tool used (VALT 'Open') will allow cause of conversion and nature of conversion to be tracked and audited during the development of a video-assisted thoracoscopic surgery lobectomy program.
