RESUMEN
There are no internationally recognized criteria available to determine preparedness for hospital discharge after esophagectomy. This study aims to achieve international consensus using Delphi methodology. The expert panel consisted of 40 esophageal surgeons spanning 16 countries and 4 continents. During a 3-round, web-based Delphi process, experts voted for discharge criteria using 5-point Likert scales. Data were analyzed using descriptive statistics. Consensus was reached if agreement was ≥75% in round 3. Consensus was achieved for the following basic criteria: nutritional requirements are met by oral intake of at least liquids with optional supplementary nutrition via jejunal feeding tube. The patient should have passed flatus and does not require oxygen during mobilization or at rest. Central venous catheters should be removed. Adequate analgesia at rest and during mobilization is achieved using both oral opioid and non-opioid analgesics. All vital signs should be normal unless abnormal preoperatively. Inflammatory parameters should be trending down and close to normal (leucocyte count ≤12G/l and C-reactive protein ≤80 mg/dl). This multinational Delphi survey represents the first expert-led process for consensus criteria to determine 'fit-for-discharge' status after esophagectomy. Results of this Delphi survey may be applied to clinical outcomes research as an objective measure of short-term recovery. Furthermore, standardized endpoints identified through this process may be used in clinical practice to guide decisions regarding patient discharge and may help to reduce the risk of premature discharge or prolonged admission.

Delayed gastric conduit emptying (DGCE) after esophagectomy for cancer is associated with adverse outcomes and troubling symptoms. Widely accepted diagnostic criteria and a symptom grading tool for DGCE are missing. This hampers the interpretation and comparison of studies. A modified Delphi process, using repeated web-based questionnaires, combined with live interim group discussions was conducted by 33 experts within the field, from Europe, North America, and Asia. DGCE was divided into early DGCE if present within 14 days of surgery and late if present later than 14 days after surgery. The final criteria for early DGCE, accepted by 25 of 27 (93%) experts, were as follows: >500 mL diurnal nasogastric tube output measured on the morning of postoperative day 5 or later or >100% increased gastric tube width on frontal chest x-ray projection together with the presence of an air-fluid level. The final criteria for late DGCE accepted by 89% of the experts were as follows: the patient should have 'quite a bit' or 'very much' of at least two of the following symptoms; early satiety/fullness, vomiting, nausea, regurgitation or inability to meet caloric need by oral intake and delayed contrast passage on upper gastrointestinal water-soluble contrast radiogram or on timed barium swallow. A symptom grading tool for late DGCE was constructed grading each symptom as: 'not at all', 'a little', 'quite a bit', or 'very much', generating 0, 1, 2, or 3 points, respectively. For the five symptoms retained in the diagnostic criteria for late DGCE, the minimum score would be 0, and the maximum score would be 15. The final symptom grading tool for late DGCE was accepted by 27 of 31 (87%) experts. For the first time, diagnostic criteria for early and late DGCE and a symptom grading tool for late DGCE are available, based on an international expert consensus process.

Esophageal cancer and its treatment can cause serious morbidity/toxicity. These effects on health-related quality of life (HRQOL) can be measured using disease-specific scales such as FACT-E, generic scales such as EQ-5D-3L, or through symptoms. In a two-year cross-sectional study, we compared HRQOL across esophageal cancer patients treated in an ambulatory clinic and across multiple disease states, among patients with all stages of esophageal cancer. Consenting patients completed FACT-E, EQ-5D, a visual analog scale, and patient reported (PR)-ECOG. Symptom complexes were constructed from FACT-E domains. Responses were categorized by disease state: pre-, during, and post-treatment, surveillance, progression, and palliative chemotherapy. Spearman correlation and multivariable linear regression characterized these associations. In total, 199 patients completed 317 questionnaires. Mean FACT-E and subscale scores dropped from baseline through treatment and recovered during post-treatment surveillance (P < 0.001); EQ-5D health utility scores (HUS) displayed a similar pattern but with smaller differences (P = 0.07), and with evidence of ceiling effect. Among patients with stage II/III esophageal cancer, mean EQ-5D HUS varied across disease states (P < 0.001), along with FACT-E and subscales (P < 0.001). Among patients with advanced disease, there was no significant difference between baseline and on-treatment total scores, but improved esophageal cancer-specific scales were noted (P = 0.003). Strong correlation was observed between EQ-5D and FACT-E (R = 0.73), along with physical and functional subscales. In addition, the association between FACT-E and EQ-5D HUS was maintained in a multivariable model (P < 0.001). We interpret these results to suggest that in a real-world clinic setting, FACT-E, EQ-5D HUS, and symptoms were strongly correlated. Most HRQOL and symptom parameters suggested that patients had worse HRQOL and symptoms during curative therapy, but recovered well afterwards. In contrast, palliative chemotherapy had a neutral to positive impact on HRQOL/symptoms when compared to their baseline pre-treatment state.

BACKGROUND: Practice guidelines from the National Comprehensive Cancer Network and the American Society of Clinical Oncology recommend pathologic mediastinal staging and surgical resection for patients with clinically node-negative T1/T2 small cell lung cancer (SCLC), but the extent to which surgery is used is unknown. We sought to assess trends and practice patterns in the use of surgery for SCLC. METHODS: T1 or T2N0M0 SCLC cases were identified in the National Cancer Database (NCDB), 2004-2013. Characteristics of patients undergoing resection were analyzed. Hierarchical logistic regression was used to identify individual and hospital-level predictors of receipt of surgery, adjusting for clinical, demographic and facility characteristics. Trends in resection rates were analyzed over the study period. FINDINGS: 9740 patients were identified with clinical T1 or T2 N0M0 SCLC. Of these, 2210 underwent surgery (22.7%), with 1421 (64.3%) undergoing lobectomy, 739 (33.4%) sublobar resections and 50 (2.3%) pneumonectomies. After adjustment, Medicaid patients were less likely to receive surgery (OR0.65 95% CI 0.48-0.89, p=0.006), as were those with T2 tumors (OR0.25 CI0.22-0.29, p<0.0001). Academic facilities were more likely to resect eligible patients (OR 1.90 CI1.45-2.49, p<0.0001). Between 2004 and 2013, resection rates more than doubled from 9.1% to 21.7%. Overall, 68.7% of patients were not offered surgery despite having no identifiable contraindication. In patients not receiving surgery, only 7% underwent pathologic mediastinal staging. INTERPRETATION: Rates of resection are increasing, but two thirds of potentially eligible patients fail to undergo surgery. Further study is required to address the lack of concordance between guidelines and practice.

BACKGROUND: The role of surgery in small cell lung cancer (SCLC) is controversial. Survival outcomes for resection of stage I-IIIA SCLC compared to chemotherapy-based non-surgical treatment (NST) were examined using propensity matching. METHODS: 29,994 clinical stage I-IIIA SCLC patients, including 2,619 undergoing surgery, were identified in the National Cancer Database. Stage-specific propensity scores for receipt of surgery were created. Resected patients were matched 1:1 to those undergoing NST. Overall survival (OS) was assessed using Kaplan-Meier and multivariable Cox models. A separate match was performed comparing Stage I/II patients aged <85 with a Charlson score of 0 who underwent lobectomy with adjuvant chemotherapy (and radiotherapy if node positive) to those treated with multiagent chemotherapy and concurrent chest radiotherapy (CRT) of at least 40 gray. RESULTS: 2,089 patients were matched, and cohorts were well balanced. Surgery was associated with longer survival for Stage I (median OS 38.6 months vs. 22.9 months, HR 0.62 95%CI 0.57-0.69, p<0.0001), but survival differences were attenuated for Stage II (median OS 23.4 months vs. 20.7 months, HR 0.84 95%CI 0.70-1.01, p=0.06) and IIIA (median OS 21.7 vs. 16.0 months, HR 0.71 95%CI 0.60-0.83, p <0.0001). In analyses by T and N stage, longer OS was observed in resected patients with stage T3/T4 N0 (median OS 33.0 vs. 16.8 months, p=0.008) and node positivity(N1+ 24.4 vs. 18.3 months p=0.03; N2+ 20.1 vs. 14.6 months p=0.007). In the subgroup analysis, 507 stage I/II patients receiving lobectomy and adjuvant chemotherapy were matched to patients receiving concurrent CRT. In this cohort, lobectomy with adjuvant chemotherapy was associated with significantly longer survival (median OS 48.6 vs. 28.7 months, p<0.0001). CONCLUSIONS: Surgical resection is associated with significantly longer survival for early SCLC. New randomized trials should assess trimodality therapy in stages I/II, and in node negative disease.

Gastroesophageal reflux disease (GERD) may lead to Barrett's esophagus (BE). Previously, a large genome-wide association study found two germline markers to be associated with BE, FOXF1 rs9936833 (C allele) and MHC rs9257809 (A allele). This study evaluated whether these two polymorphisms are associated with gastroesphageal acid reflux as measured by 24-hour pH testing. Patients with acid reflux symptoms referred for esophageal manometry and 24-hour pH monitoring at University Health Network (Toronto, ON) were enrolled. DNA extracted from blood was genotyped using a Taqman Polymerase Chain Reaction (PCR) assay. DeMeester scores of ≥14.7 or prior evidence of reflux esophagitis on endoscopy defined individuals with esophageal acid reflux. Logistic regression analysis, adjusted for clinical risk factors, was used to calculate odds ratios with 95% confidence intervals for each polymorphism in relation to the presence of acid reflux. Of 182 patients, the median age was 50 years and 62% were female; 95 (52%) met the definition of GERD. In the multivariable analysis, both FOXF1 rs9936833 (OR = 1.82; 95%CI: 1.12-2.96; P = 0.02) and MHC rs9257809 (OR = 9.36; 95%CI: 2.92-29.99; P < 0.001) remained significantly associated with presence of acid reflux. When both polymorphisms were placed in the same model, the adjusted ORs were 2.10 (95%CI: 1.24-3.53; P = 0.005) and 10.95 (95%CI: 3.32-36.09; P < 0.001), respectively. The association for risk allele C in FOXF1 rs9936833 and risk allele A in MHC rs9257809 with the presence of acid reflux suggests a potential pathophysiologic mechanism for the role of genetic influences in BE development.

We report data-simple descriptions of patient characteristics, cancer categories, and non-risk-adjusted survival-for patients with pathologically staged cancer of the esophagus and esophagogastric junction after resection or ablation with no preoperative therapy from the Worldwide Esophageal Cancer Collaboration (WECC). Thirty-three institutions from six continents submitted de-identified data using standard definitions: demographics, comorbidities, clinical cancer categories, and all-cause mortality from first management decision. Of 13,300 patients, 5,631 had squamous cell carcinoma, 7,558 adenocarcinoma, 85 adenosquamous carcinoma, and 26 undifferentiated carcinoma. Patients were older (62 years) men (80%) with normal body mass index (51%), little weight loss (1.8 kg), 0-2 ECOG performance status (83%), and a history of smoking (70%). Cancers were pT1 (24%), pT2 (15%), pT3 (50%), pN0 (52%), pM0 (93%), and pG2-G3 (78%); most involved distal esophagus (71%). Non-risk-adjusted survival for both squamous cell carcinoma and adenocarcinoma was monotonic and distinctive across pTNM. Survival was more distinctive for adenocarcinoma than squamous cell carcinoma when pT was ordered by pN. Survival for pTis-1 adenocarcinoma was better than for squamous cell carcinoma, although monotonic and distinctive for both. WECC pathologic staging data is improved over that of the 7th edition, with more patients studied and patient and cancer variables collected. These data will be the basis for the 8th edition cancer staging manuals following risk adjustment for patient, cancer, and treatment characteristics, and should direct 9th edition data collection. However, the role of pure pathologic staging as the principal point of reference for esophageal cancer staging is waning.

To address uncertainty of whether clinical stage groupings (cTNM) for esophageal cancer share prognostic implications with pathologic groupings after esophagectomy alone (pTNM), we report data-simple descriptions of patient characteristics, cancer categories, and non-risk-adjusted survival-for clinically staged patients from the Worldwide Esophageal Cancer Collaboration (WECC). Thirty-three institutions from six continents submitted data using variables with standard definitions: demographics, comorbidities, clinical cancer categories, and all-cause mortality from first management decision. Of 22,123 clinically staged patients, 8,156 had squamous cell carcinoma, 13,814 adenocarcinoma, 116 adenosquamous carcinoma, and 37 undifferentiated carcinoma. Patients were older (62 years) men (80%) with normal body mass index (18.5-25 mg/kg2 , 47%), little weight loss (2.4 ± 7.8 kg), 0-1 ECOG performance status (67%), and history of smoking (67%). Cancers were cT1 (12%), cT2 (22%), cT3 (56%), cN0 (44%), cM0 (95%), and cG2-G3 (89%); most involved the distal esophagus (73%). Non-risk-adjusted survival for squamous cell carcinoma was not distinctive for early cT or cN; for adenocarcinoma, it was distinctive for early versus advanced cT and for cN0 versus cN+. Patients with early cancers had worse survival and those with advanced cancers better survival than expected from equivalent pathologic categories based on prior WECC pathologic data. Thus, clinical and pathologic categories do not share prognostic implications. This makes clinically based treatment decisions difficult and pre-treatment prognostication inaccurate. These data will be the basis for the 8th edition cancer staging manuals following risk adjustment for patient characteristics, cancer categories, and treatment characteristics and should direct 9th edition data collection.

To address uncertainty of whether pathologic stage groupings after neoadjuvant therapy (ypTNM) for esophageal cancer share prognostic implications with pathologic groupings after esophagectomy alone (pTNM), we report data-simple descriptions of patient characteristics, cancer categories, and non-risk-adjusted survival-for pathologically staged cancers after neoadjuvant therapy from the Worldwide Esophageal Cancer Collaboration (WECC). Thirty-three institutions from six continents submitted data using variables with standard definitions: demographics, comorbidities, clinical cancer categories, and all-cause mortality from first management decision. Of 7,773 pathologically staged neoadjuvant patients, 2,045 had squamous cell carcinoma, 5,686 adenocarcinoma, 31 adenosquamous carcinoma, and 11 undifferentiated carcinoma. Patients were older (61 years) men (83%) with normal (40%) or overweight (35%) body mass index, 0-1 Eastern Cooperative Oncology Group performance status (96%), and a history of smoking (69%). Cancers were ypT0 (20%), ypT1 (13%), ypT2 (18%), ypT3 (44%), ypN0 (55%), ypM0 (94%), and G2-G3 (72%); most involved the distal esophagus (80%). Non-risk-adjusted survival for yp categories was unequally depressed, more for earlier categories than later, compared with equivalent categories from prior WECC data for esophagectomy-alone patients. Thus, survival of patients with ypT0-2N0M0 cancers was intermediate and similar regardless of ypT; survival for ypN+ cancers was poor. Because prognoses for ypTNM and pTNM categories are dissimilar, prognostication should be based on separate ypTNM categories and groupings. These data will be the basis for the 8th edition cancer staging manuals following risk adjustment for patient, cancer, and treatment characteristics and should direct 9th edition data collection.

This prospective population-based study was designed to evaluate treatment choices in patients with new manometrically diagnosed achalasia and their outcomes. Patients referred to the esophageal function laboratory were enrolled after a new manometric diagnosis of achalasia. Patients completed an initial achalasia symptom score validated questionnaire on their symptom severity, duration, treatment pre-diagnosis and Medical Outcomes Study 36-item Short-Form (SF-36) survey. Treatment decisions were made by the referring physician and the patient. Follow-up questionnaires were completed every 3 months for 1 year. Patients who chose not to undergo treatment at 1-year follow-up completed another questionnaire after 5 years. Between January 2004 and January 2005, 83 of 124 eligible patients were enrolled. Heller myotomy was performed on 31 patients, three patients received botulinum toxin injections, and 25 patients received 29 pneumatic balloon dilatations. Twenty-four patients chose to receive no treatment. Following treatment, patients treated with surgery, dilatation and botulinum toxin had an average improvement in achalasia symptom score of 23 +/- 12.2, 17 +/- 10.9, and 9 +/- 14, respectively. Patients receiving no treatment had worsening symptoms with a symptom score change of -3.5 +/- 11.4. Surgery and dilatation resulted in significant improvement (P < 0.01) relative to no treatment. In univariate logistic regression, symptom severity score (odds ratio [OR] 1.04, 95% confidence interval [CI] 1.00 to 1.08), sphincter tone (OR 1.04, 95% CI 1.00 to 1.09), difficulty swallowing liquids (OR 3.21, 95% 1.15 to 8.99), waking from sleep (OR 2.75, 95% 1.00 to 7.61), and weight loss (OR 5.99, 95% CI 1.93 to 18.58) were all significant in predicting that patients would select treatment. In the multivariate analysis, older age (OR 1.05, 95% CI 1.01 to 1.09) and weight loss (OR 3.91, 95% CI 1.02 to 15.2) were statistically significant for undergoing treatment. At 5 years, five (21%) of those who had initially declined treatment at 1 year ultimately chose a treatment. Patients who finally chose Heller myotomy had lower mental component dimension scores on the SF-36 at 1 year than those who did not. This study shows that almost one third of patients with manometrically diagnosed achalasia choose not to undergo treatment within 1 year of their diagnosis. Patients who are more symptomatic appear to be more likely to undergo treatment by univariate analysis. In multivariate analysis, increasing age and weight loss are predictive of those who will undergo treatment, with weight loss having the greatest influence. Patients who choose not to undergo treatment make lifestyle changes to maintain their quality of life, and only a minority of them ultimately undergo treatment.

INTRODUCTION: In non-small-cell lung cancer (nsclc), invasive mediastinal staging is typically used to guide treatment decision-making. Here, we present clinical practice guideline recommendations for invasive mediastinal staging in nsclc patients who have been staged T1-4, N0-3, with no distant metastases. METHODS: Draft recommendations were formulated based on the best available evidence gathered by a systematic review and a consensus of expert opinion. The draft recommendations underwent an internal review by clinical and methodology experts, and an external review by clinical practitioners through a survey assessing the clinical relevance and overall quality of the guideline. Feedback from the internal and external reviews was integrated into the clinical practice guideline. RESULTS: In general, most clinical experts agreed with the guideline, approving it for methodologic rigour. More than 80% of the surveyed practitioners gave it a high quality rating. The expert reviewers also provided written comments, with some of the suggested changes being incorporated into the final version of the guideline. CONCLUSIONS: In the clinical practice guideline, invasive mediastinal staging of nsclc is recommended in all cases except those involving patients with normal-sized lymph nodes, negative combine positron-emission tomography and computed tomography, and peripheral clinical stage 1A tumour. When performing mediastinoscopy, 5 nodal stations (2R/L, 4R/L, and 7) should routinely be examined.
RESUMEN
BACKGROUND: In patients with apparently operable non-small cell lung cancer (NSCLC), clinicians often omit investigation for M disease in asymptomatic patients. Previous investigations have not specified in detail what is meant by "symptomatic," and this could differ between surgeons. We have investigated the extent to which surgeons' criteria differ for presence of symptoms. METHODS: Participating surgeons from seven centers, enrolled patients they judged "asymptomatic" in a randomized trial of investigational strategies for NSCLC. Patients completed a structured questionnaire describing symptoms of the central nervous system (CNS). In 685 patients, we documented CNS symptom recurrence after resectional surgery over 1 year of follow-up. RESULTS: Two centers enrolled only patients without even the mildest symptoms. Three centers took an intermediate approach, occasionally classifying patients with mild symptoms as "asymptomatic" and thus enrolling them in the trial. Two centers classified an appreciable number of patients with minimal symptoms, and occasionally with more than minimal symptoms, as "asymptomatic." Patients with even mild CNS symptoms were more likely to subsequently present with CNS metastases. CONCLUSIONS: Thoracic surgeons differ in their ideas of what may constitute the symptoms of M disease. Patients with structured questionnaire results that suggest symptoms of CNS disease are more likely to have CNS symptom recurrence after resectional surgery.

Patients with SCLC should have a complete history and physical examination with particular attention paid to symptoms and signs of extensive disease and paraneoplastic syndromes. Hematology and biochemistry should be obtained at the initial assessment. A chest radiograph will usually have been performed prior to diagnosis. Further imaging should then be done to determine if the patient has limited or extensive disease. In the nonprotocol setting, extensive radiologic investigations are not required once a site of metastatic disease has been identified. If symptoms or signs are present to indicate a site of extensive disease, then this should direct the next test. In the absence of any specific findings then either bone scan or abdominal imaging with either US or CT scanning may be done based on the roughly equal likelihood of metastatic disease in liver or bone. Because a bone scan is less expensive, it is often the next test selected. If the bone scan is negative, abdominal imaging should then be performed, followed by brain CT scan. If these investigations are negative, the next study should be a thoracic CT scan. Bone marrow examination is probably unnecessary in the nonprotocol setting unless serum LDH levels are elevated. In the setting of a clinical trial, complete staging should be done and even more precise staging using the TNM system should be considered based on the improved survival of patients with proven stage I disease. Using more precise staging will allow accurate comparisons of clinical trials and eliminate or minimize the question of patient selection. Surgical staging with mediastinoscopy may come to have a role in accurately determining stage I or II disease.

This retrospective study of 100 consecutive patients with inhalation injury documents that adult respiratory distress syndrome (ARDS) and pneumonia are common complications. Pulmonary complications cause or directly contribute to death in 77% of patients with combined inhalation and cutaneous burn injury. Additionally, the high fluid requirements of these patients worsens their pulmonary injury and is associated with adverse outcome. Independent factors predictive of death include ARDS and expected fluid requirements as well as age and percentage of total body surface area burned. An abnormal chest roentgenogram in the first 48 hours after injury is also associated with death. The development of ARDS is predicted by the actual volume of fluid resuscitation, despite normal pulmonary wedge pressure or normal central venous pressure reflecting increased microvascular permeability. These findings indicate a need for reevaluation of fluid resuscitation of patients with inhalation injury.

STUDY DESIGN: This study reports the experience with four patients regarding a modified anterior approach to the cervicothoracic junction. OBJECTIVES: This technique was evaluated with respect to extent of exposure, ease of technique, and postoperative morbidity. SUMMARY OF BACKGROUND DATA: Previously reported anterior approaches to the cervicothoracic junction have described either full sternotomy resection of the left sternoclavicular junction or osteotomy of the clavicle. A simplified approach was chosen using a partial sternotomy, which has not been described previously for approaches to the spine. METHODS: Four patients with metastatic disease, in the region of the cervicothoracic junction, required decompression and stabilization for palliation of symptoms. An anterior approach was required for decompression. A standard cervical approach was combined with a partial median sternotomy and transverse osteotomy through the synostosis between the manubrium and body of the sternum. In three patients, the left innominate vein was divided. Decompression and anterior stabilization were followed by posterior stabilization at an interval of 4 to 7 days. RESULTS: This procedure was simple to perform, requiring little additional operative time for opening or closure. It provided excellent exposure from C3-T4. There was no associated morbidity related to the division of the manubrium or innominate vein. CONCLUSION: Partial sternotomy combined with a standard cervical incision provides excellent exposure to the cervicothoracic junction from C3-T4. It is technically simple to perform and avoids the risk of injury to subclavian vessels inherent in resection of the clavicle or sternoclavicular junction. There is no additional morbidity associated with this approach.

We have studied 159 patients 80 years of age or older who have had isolated coronary artery bypass grafting (CABG) since 1977. Eighty-seven percent have had surgery since 1984. Two thirds of the patients were male, and the mean age was 82 years. Most patients (97%) were in New York Heart Association (NYHA) functional class III or IV, 89% had unstable/postinfarction angina pectoris, and 67% had rest pain. Almost half (47%) required preoperative admission to the coronary care unit, 6% required preoperative use of an intra-aortic balloon pump, and 20% were operated on emergently. Significant left main coronary artery disease (greater than or equal to 50% stenosis) was present in 41%. Ten patients (6.3%) died within 30 days of surgery, with seven more patients dying during the same hospital admission or soon after transfer to another institution. This resulted in an overall hospital mortality of 10.7%. The median hospital stay was 10 days. On univariate analysis, the significant predictors of hospital mortality were NYHA IV, angina at rest, preoperative admission to the coronary care unit, emergency operation, ejection fraction less than 0.50, and the presence of mitral regurgitation. On multivariate analysis, ejection fraction less than 0.50 was the only significant risk factor (p less than 0.01). Of hospital survivors, 98% have been followed for a mean of 29 months. The estimated 5-year survival (+/- SEM) of all patients was 71 +/- 4.5%, and for hospital survivors, 80 +/- 4.5%. The most important predictor of adverse survival was an ejection fraction less than 0.50. Seventy-nine percent are angina-free, and 89% are in NYHA classes I and II. The majority of patients felt that they were improved by surgery. We conclude that CABG in patients 80 years or older, although associated with increased operative risk, gives excellent relief of symptoms and good 5-year survival. Patients should not be denied CABG because of age alone.

Twenty-five consecutive patients with either persistent or recurrent symptomatic primary hyperparathyroidism after 36 prior operations were prospectively studied to compare the usefulness of intraoperative measurement of urinary cyclic adenosine monophosphate (UcAMP) levels with standard surgical procedures to predict outcome during tedious parathyroid reoperations. The criterion based on UcAMP to predict successful outcome was a 50% decline in intraoperative UcAMP levels from the median baseline level after removal of abnormal parathyroid tissue. Standard surgical criteria were resection of four abnormal glands for hyperplasia and resection of one abnormal gland and biopsy examination of one normal gland for adenoma. In 15 patients (60%) surgery was terminated on the basis of UcAMP criterion. In one patient elevated UcAMP levels never changed and correctly predicted unsuccessful surgery. In nine patients surgery was terminated on the basis of surgical criteria, and each of these patients had a successful outcome. Operative UcAMP levels dropped after the completion of the procedure in six of these latter nine patients. Three patients did not show a significant decrease in UcAMP levels despite successful surgery, and one patient displayed an early false-positive decrease in UcAMP level. The intraoperative UcAMP criterion accurately predicted outcome in 21 of 25 patients (84%). Sensitivity of the UcAMP criterion was 87% and specificity was 50%. The results indicate that by either method a reliable prediction of the outcome of reoperative parathyroid surgery may be made. Intraoperative determination of UcAMP levels will allow successful termination of the reoperation in some patients before operative identification of adequate parathyroid tissue necessary to confidently establish the pathologic diagnosis.

Of 1136 patients admitted consecutively to two medical-surgical intensive care units, 100 were found to have multiorgan failure, defined as failure of more than two organ systems. The average duration of stay in the intensive care units was 13.4 days. The overall death rate was 78% compared with 12.8% for patients without multiorgan failure. The most common initiating illnesses or insults were sepsis, surgery, accidental trauma and cardiogenic shock. Of potential risk factors studied, shock, sepsis, surgery, pre-existing organ disease and age over 65 years were the most common. Although sepsis occurred before or during the course of multiorgan failure in 78 patients, in only 34 was sepsis judged to be the prime insult leading to multiorgan failure. Surgery during the course of multiorgan failure had neither an adverse nor beneficial effect on outcome. The mean number of organ systems failing was 4.36 for survivors and 5.03 for nonsurvivors. The most common systems to fail were central nervous, cardiovascular and respiratory.
