Summary
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.

Purpose
To determine the accuracy of final judgements of doctors at the emergency department (ED) and radiologists to differentiate between complicated and uncomplicated acute appendicitis, because ...these have different treatment options.
Methods
This prospective, multicenter study included adult patients with imaging-confirmed acute appendicitis, operated with intention to appendectomy. Both doctors at ED and radiologists assessed appendicitis severity as a final judgement of “uncomplicated” or “complicated” appendicitis. Doctors at ED integrated clinical, laboratory, and imaging findings. Radiologists relied solely on imaging findings. Outcomes were accuracy of these judgements for diagnosis of complicated appendicitis compared to the reference standard by an adjudication committee.
Results
After imaging, 1070 patients with confirmed acute appendicitis were included. Doctors at ED accurately labelled 656 of 701 (93.6%) patients with true uncomplicated appendicitis as uncomplicated, and 163 of 369 (44.2%) patients with true complicated appendicitis were labelled as complicated. Sensitivity, specificity, and positive and negative predictive values (PPV and NPV) for complicated appendicitis were 44.2%, 93.6%, and 78.4% and 76.1%, respectively. Comparable accuracy was found for the radiologist’s assessment in 941 patients, with true positive rates of 92.2% (581 of 630 patients) for uncomplicated appendicitis and 46.6% (145 of 311 patients) for complicated appendicitis.
Conclusion
More than half of all patients with true complicated appendicitis is incorrectly classified as uncomplicated appendicitis according to the judgements of doctors at ED, integrating clinical, laboratory, and imaging results, and of radiologists assessing diagnostic imaging. These judgements are thereby not sufficiently reliable in ruling out complicated appendicitis.
Background
Survival after oesophagectomy for cancer seems to be improving. This study aimed to identify the most important contributors to this change.
Methods
Patients who underwent oesophagectomy ...from 1999 to 2010 were extracted from the Netherlands Cancer Registry. Four time periods were compared: 1999–2001 (period 1), 2002–2004 (period 2), 2005–2007 (period 3) and 2008–2010 (period 4). Hospital type, tumour location, tumour type, tumour differentiation, neoadjuvant therapy, operation type, (y)pT category, involvement of surgical resection margins, number of removed lymph nodes and number of involved lymph nodes were investigated in relation to trends in survival using multivariable analysis.
Results
A total of 4382 patients were identified. Two‐year overall survival rates improved from 49·3 per cent in period 1 to 58·4, 56·2 and 61·0 per cent in periods 2, 3 and 4 respectively (P < 0·001). Multivariable survival analysis revealed that the improvement in survival between periods 3 and 4 was related to the introduction of neoadjuvant therapy. The improvement in survival between periods 1 and 2 could not be explained completely by the factors studied. The number of examined lymph nodes increased, especially between periods 2 and 3, but this increase was not associated with the improvement in survival.
Conclusion
The observed increase in long‐term survival after surgery for oesophageal cancer between 1999 and 2010 in the Netherlands is difficult to explain fully, although the recent increase seems to be partly attributable to the introduction of neoadjuvant therapy.
Main source of improvement seems to be neoadjuvant therapy
Abstract
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.

Substantial variation in the use of (neo) adjuvant treatment in patients with gastric cancer exists. The aim of this study was to identify underlying (organizational and process) factors associated ...with the use of perioperative therapy.
Patients with resectable gastric cancer who underwent surgery between 2012 and 2014 were selected from the Dutch Upper gastrointestinal Cancer Audit (DUCA). The proportion of perioperatively treated patients was defined per hospital. Five hospitals with the lowest percentage (LP group) and 5 hospitals with the highest percentage (HP group) of perioperative therapy were identified. In the selected hospitals additional information was obtained from patients' medical records using a structured list with predefined variables.
In total, 429 patients (231 in LP group, 198 in HP group) from 9 different hospitals were included. Perioperative therapy was given in 16.0% of patients in the LP group compared to 40.4% in the HP group. In the LP group, patients were enrolled in a clinical trial less frequently (10.8% versus 26.8%, P<.001), and a higher percentage grade III-IV toxicity was observed during neoadjuvant treatment (25.7% versus 46.3%, P=.007). Multivariable analysis showed that, besides known casemix factors, consultation with ≥3 upper GI specialists prior to treatment decision was positively associated with initiating perioperative therapy (OR 2.08, 95% CI 1.19–3.66).
Results of this study confirm considerable hospital variation in the use of perioperative therapy in patients with gastric cancer. Besides known casemix factors, use of perioperative therapy was associated with the level of involvement of multidisciplinary care.
Abstract
Aim
The aim this study was to investigate possible differences in outcomes between Ivor-Lewis (IL) versus McKeown esophagectomy (MK) in a population based cohort.
Background
It is unknown ...whether IL or MK should be preferred in patients with potentially curable locoregionally oesophageal or gastro-oesophageal junction (GEJ) cancer.
Methods
Oesophageal and GEJ cancer patients without distant metastases who underwent a transthoracic oesophagectomy between 2015 and 2017 were selected from the Netherlands Cancer Registry. Patient and tumour characteristics, and treatment outcomes were analysed and compared between IL and MK after propensity score matching (PSM). Patients were matched based on sex, age, tumour morphology and topography, comorbidities, neoadjuvant treatment, cT and cN stage, ASA-score and hospital volume. Postoperative complications and survival were compared between both groups using Chi-Square and multivariable Cox regression analyses. In the multivariable Cox regression analyses we corrected for infectious complications (wound complications and pneumonia) and anastomotic leakage to investigate its effect on survival.
Results
Off all 1764 included patients (1201 IL patients and 563 MK patients), 948 patients remained after matching. Significantly more lymph nodes were yielded after IL compared to MK (P=0.02). Surgical radicality did not differ between both groups (P=0.25). The complication rate was significantly lower in the IL group regarding anastomotic leakage (17% vs. 28%, P<0.0007) and recurrent laryngeal nerve palsy (2% vs. 6%, P<0.001). Cardiac complications were seen more frequently in patients who underwent IL (17% vs. 11%, P<0.02). No differences were observed in 30 day and 90 day mortality. Kaplan-Meier showed a better survival for IL (63%) compared to MK (58%) (log-rank p=0.07). When correcting for anastomotic leakage and infectious complications the difference in survival remained (HR=0.84, 95% CI 0.69 – 1.03). Similar results regarding postoperative complications and survival were observed in the unmatched cohort.
Conclusion
Patients who underwent an IL have better outcomes in terms of anastomotic leakage and recurrent laryngeal nerve palsy rate and overall survival compared to MK. The difference in survival appears not to be related to the differences in infectious complications. Based on these results, IL appears to be the treatment of choice in patients in whom both oncological resections are appropriate.

Objectives: The report describes the strategic design, steps to full implementation and outcomes achieved by the Western Australian Data Linkage System (WADLS), instigated in 1995 to link up to 40 ...years of data from over 30 collections for an historical population of 3.7 million. Staged development has seen its expansion, initially from a linkage key to local health data sets, to encompass links to national and local health and welfare data sets, genealogical links and spatial references for mapping applications. Applications: The WADLS has supported over 400 studies with over 250 journal publications and 35 graduate research degrees. Applications have occurred in health services utilisation and outcomes, aetiologic research, disease surveillance and needs analysis, and in methodologic research. Benefits: Longitudinal studies have become cheaper and more complete; deletion of duplicate records and correction of data artifacts have enhanced the quality of information assets; data linkage has conserved patient privacy; community machinery necessary for organised responses to health and social problems has been exercised; and the commercial return on research infrastructure investment has exceeded 1000%. Most importantly, there have been unbiased contributions to medical knowledge and identifiable advances in population health arising from the research.
