Background
S
urvival after curative gastrectomy for gastric cancer varies depending on region. The 5-year survival rates in Western trials reach 36–47 % compared with 40–60 % in Japanese studies. We analyzed the outcomes of Asian and non-Asian patients at a single Australian institution.
Methods
We analyzed a prospectively kept database of patients following gastric resection between 1994 and 2010 at a tertiary Australian hospital. Overall survival was the primary endpoint.
Results
A total of 160 patients underwent a R0 gastrectomy with curative intent, of whom 26 (16 %) were of Asian descent. Asian patients had a significantly younger age at diagnosis (60 ± 16 vs. 70 ± 11,
p
< 0.05) and longer overall survival (log-rank
p
= 0.018). Poor prognostic factors common to both groups included increased tumor length, higher T-score, higher LN ratio, poor tumor differentiation, and the presence of perineural or perivascular invasion. Multivariate analysis showed that non-Asian patients, higher T-score, higher N-score, and perivascular involvement were all independent predictors of poorer outcome.
Conclusions
This study shows superior overall survival in Asian patients despite similar clinicopathological and treatment data. The younger age at diagnosis in Asian patients may suggest a different disease process between ethnicities. Targeted therapies based on population-specific tumor biology may potentially be beneficial.

Identification of low muscle mass becomes increasingly relevant due to its prognostic value in cancer patients. In clinical practice, mid-upper arm muscle circumference (MAMC) and bioelectrical impedance analysis (BIA) are often used to assess muscle mass. For muscle-mass assessment, computed tomography (CT) is considered as reference standard. We investigated concordance between CT, BIA, and MAMC, diagnostic accuracy of MAMC, and BIA to detect low muscle mass and their relation with the clinical outcome malnutrition provided with the Patient-Generated Subjective Global Assessment Short Form (PG-SGA SF). This cross-sectional study included adult patients with advanced esophageal and gastrointestinal cancer. BIA, MAMC, and PG-SGA-SF were performed. Routine CT-scans were used to quantify psoas muscle index (PMI) and skeletal muscle area. Good concordance was found between CTPMI and both BIAFFMI (fat free mass index) (ICC 0.73), and BIAASMI (appendicular skeletal muscle index) (ICC 0.69) but not with MAMC (ICC 0.37). BIAFFMI (94%), BIAASMI (86%), and MAMC (86%) showed high specificity but low sensitivity. PG-SGA-SF modestly correlated with all muscle-mass measures (ranging from −0.17 to −0.43). Of all patients with low muscle mass, 62% were also classified with a PG-SGA-SF score of ≥4 points. Although CT remains the first choice, since both BIA and MAMC are easy to perform by dieticians, they have the potential to be used to detect low muscle mass in clinical practice.

Intestinal preservation for transplantation is accompanied by hypoperfusion with long periods of ischemia with total blood cessation and absolute withdrawal of oxygen leading to structural damage. The application of intraluminal oxygen has been successfully tested in small-animal series during storage and transport of the organ but have been so far clinically unrelatable. In this study, we tested whether a simple and clinically approachable method of intraluminal oxygen application could prevent ischemic damage in a large animal model, during warm ischemia time. We utilised a local no-flow ischemia model of the small intestine in pigs. A low-flow and high-pressure intraluminal oxygen deliverance system was applied in 6 pigs and 6 pigs served as a control group. Mucosal histopathology, hypoxia and barrier markers were evaluated after two hours of no-flow conditions, in both treatment and sham groups, and in healthy tissue. Macro- and microscopically, the luminal oxygen delivered treatment group showed preserved small bowel’s appearance, viability, and mucosal integrity. A gradual deterioration of histopathology and barrier markers and increase in hypoxia-inducible factor 1-α expression towards the sites most distant from the oxygen application was observed. Intraluminal low-flow, high oxygen delivery can preserve the intestinal mucosa during total ischemia of the small intestine. This finding can be incorporated in methods to overcome small bowel ischemia and improve intestinal preservation for transplantation.

Outcome after cholecystectomy in the elderly
2019
Cholecystectomy is considered the standard treatment for acute cholecystitis and symptomatic gallstones. An increasing number of frail elderly patients are being referred for this surgical treatment. A better understanding of surgical outcome in the elderly is needed to improve quality of care.
A retrospective analysis of 565 patients who underwent cholecystectomy was performed. Focus of the analyses was on postoperative complications and its predictors.
The study population was divided in two cohorts; aged <70. More complications were found in patients aged ≥70 years. More elderly patients were admitted to the intensive care, respectively 4.0% and 14.1% (P = 0.045). Hospital mortality was 6% in patients aged ≥70 years vs 0.6% in patients <70.
In elderly patients, the complication and mortality rate following cholecystectomy is higher than previously reported. For high-risk patients aged ≥70 with cholecystitis, alternative therapies should be considered as a bridge to surgery or definite treatment.
•Cholecystectomy in elderly patients is associated with a higher complication rate (CCI).•Complications were accompanied by a significantly longer HLOS and a higher ICU admittance rate in the elderly.•More pre-operative factors than age alone are predictors for postoperative complications.

Endoscopic or surgical step-up approach for infected necrotising pancreatitis: a multicentre randomised trial
2018
Infected necrotising pancreatitis is a potentially lethal disease and an indication for invasive intervention. The surgical step-up approach is the standard treatment. A promising alternative is the endoscopic step-up approach. We compared both approaches to see whether the endoscopic step-up approach was superior to the surgical step-up approach in terms of clinical and economic outcomes.
In this multicentre, randomised, superiority trial, we recruited adult patients with infected necrotising pancreatitis and an indication for invasive intervention from 19 hospitals in the Netherlands. Patients were randomly assigned to either the endoscopic or the surgical step-up approach. The endoscopic approach consisted of endoscopic ultrasound-guided transluminal drainage followed, if necessary, by endoscopic necrosectomy. The surgical approach consisted of percutaneous catheter drainage followed, if necessary, by video-assisted retroperitoneal debridement. The primary endpoint was a composite of major complications or death during 6-month follow-up. Analyses were by intention to treat. This trial is registered with the ISRCTN registry, number ISRCTN09186711.
Between Sept 20, 2011, and Jan 29, 2015, we screened 418 patients with pancreatic or extrapancreatic necrosis, of which 98 patients were enrolled and randomly assigned to the endoscopic step-up approach (n=51) or the surgical step-up approach (n=47). The primary endpoint occurred in 22 (43%) of 51 patients in the endoscopy group and in 21 (45%) of 47 patients in the surgery group (risk ratio [RR] 0·97, 95% CI 0·62–1·51; p=0·88). Mortality did not differ between groups (nine [18%] patients in the endoscopy group vs six [13%] patients in the surgery group; RR 1·38, 95% CI 0·53–3·59, p=0·50), nor did any of the major complications included in the primary endpoint.
In patients with infected necrotising pancreatitis, the endoscopic step-up approach was not superior to the surgical step-up approach in reducing major complications or death. The rate of pancreatic fistulas and length of hospital stay were lower in the endoscopy group. The outcome of this trial will probably result in a shift to the endoscopic step-up approach as treatment preference.

BackgroundTime of diagnosis (TOD) of benign esophageal perforation is regarded as an important risk factor for clinical outcome, although convincing evidence is lacking. The aim of this study is to assess whether time between onset of perforation and diagnosis is associated with clinical outcome in patients with iatrogenic esophageal perforation (IEP) and Boerhaave’s syndrome (BS).MethodsWe searched MEDLINE, Embase and Cochrane library through June 2018 to identify studies. Authors were invited to share individual patient data and a meta-analysis was performed (PROSPERO: CRD42018093473). Patients were subdivided in early (≤ 24 h) and late (> 24 h) TOD and compared with mixed effects multivariable analysis while adjusting age, gender, location of perforation, initial treatment and center. Primary outcome was overall mortality. Secondary outcomes were length of hospital stay, re-interventions and ICU admission.ResultsOur meta-analysis included IPD of 25 studies including 576 patients with IEP and 384 with BS. In IEP, early TOD was not associated with overall mortality (8% vs. 13%, OR 2.1, 95% CI 0.8–5.1), but was associated with a 23% decrease in ICU admissions (46% vs. 69%, OR 3.0, 95% CI 1.2–7.2), a 22% decrease in re-interventions (23% vs. 45%, OR 2.8, 95% CI 1.2–6.7) and a 36% decrease in length of hospital stay (14 vs. 22 days, p < 0.001), compared with late TOD. In BS, no associations between TOD and outcomes were found. When combining IEP and BS, early TOD was associated with a 6% decrease in overall mortality (10% vs. 16%, OR 2.1, 95% CI 1.1–3.9), a 19% decrease in re-interventions (26% vs. 45%, OR 1.9, 95% CI 1.1–3.2) and a 35% decrease in mean length of hospital stay (16 vs. 22 days, p = 0.001), compared with late TOD.ConclusionsThis individual patient data meta-analysis confirms the general opinion that an early (≤ 24 h) compared to a late diagnosis (> 24 h) in benign esophageal perforations, particularly in IEP, is associated with improved clinical outcome.

Background
The optimal extent of lymph node dissection (LND) and the anatomic boundaries per lymph node station (LNS) during minimally invasive esophagectomy (MIE) for esophageal cancer remain a topic of debate. This study investigated the opinion of Dutch esophageal cancer surgeons on their routine LND extent and anatomic boundaries per LNS during MIE.
Methods
In April 2023, an English web-based cross-sectional survey was conducted. In each of the 15 Dutch hospitals performing MIE, two MIE surgeons were asked to participate. The routine LND extent (quantity, specific LNS) for distal esophageal adenocarcinoma, (dis)agreement with the TIGER definition, and anatomic boundaries for each LNS in six directions were queried.
Results
The survey was completed by 24 Dutch MIE surgeons (80% response rate). Consensus on the routine LND extent ( ≥ 85% of the participating surgeons) included the left and right paracardial, left gastric artery, celiac trunk, proximal splenic artery, common hepatic artery, subcarinal middle mediastinal paraoesophageal, lower mediastinal paraoesophageal, pulmonary ligament, and upper mediastinal paraoesophageal LNSs. Other LNSs were not widely considered routine. Although, certain anatomic boundaries were consistent among the surgeons, the majority varied, even when they agreed on the TIGER definition.
Conclusion
Significant variations in surgical practice among Dutch esophageal surgeons regarding their routine extent of LND and anatomic boundaries of LNSs during MIE were demonstrated. Variation may have an impact on clinical outcomes, hampering uniform treatment strategies and hindering comparison of performance assessments. This study highlighted the need for an international follow-up study toward one uniform defined LND during MIE for esophageal cancer.

Postponed or immediate drainage of infected necrotizing pancreatitis (POINTER trial): study protocol for a randomized controlled trial
2019
Background
Infected necrosis complicates 10% of all acute pancreatitis episodes and is associated with 15–20% mortality. The current standard treatment for infected necrotizing pancreatitis is the step-up approach (catheter drainage, followed, if necessary, by minimally invasive necrosectomy). Catheter drainage is preferably postponed until the stage of walled-off necrosis, which usually takes 4 weeks. This delay stems from the time when open necrosectomy was the standard. It is unclear whether such delay is needed for catheter drainage or whether earlier intervention could actually be beneficial in the current step-up approach. The POINTER trial investigates if immediate catheter drainage in patients with infected necrotizing pancreatitis is superior to the current practice of postponed intervention.
Methods
POINTER is a randomized controlled multicenter superiority trial. All patients with necrotizing pancreatitis are screened for eligibility. In total, 104 adult patients with (suspected) infected necrotizing pancreatitis will be randomized to immediate (within 24 h) catheter drainage or current standard care involving postponed catheter drainage. Necrosectomy, if necessary, is preferably postponed until the stage of walled-off necrosis, in both treatment arms. The primary outcome is the Comprehensive Complication Index (CCI), which covers all complications between randomization and 6-month follow up. Secondary outcomes include mortality, complications, number of (repeat) interventions, hospital and intensive care unit (ICU) lengths of stay, quality-adjusted life years (QALYs) and direct and indirect costs. Standard follow-up is at 3 and 6 months after randomization.
Discussion
The POINTER trial investigates if immediate catheter drainage in infected necrotizing pancreatitis reduces the composite endpoint of complications, as compared with the current standard treatment strategy involving delay of intervention until the stage of walled-off necrosis.

Objective. We aimed to gain consensus on HCPs’ perspectives on self-management support information needs of patients with esophageal cancer during the preoperative phase. Methods. Based on the literature, observations of clinical consultations, and hospital patient information leaflets, a survey was created. HCPs were surveyed twice about their opinion on importance of information, from “not essential” to “absolutely essential,” using Delphi methods. Topics were included in the second round if predetermined criteria were met. To be included in the final list, topics had to meet criteria for consensus and stability. Results. 64 information items and 6 sources of support were identified. Survey response rates were 59% (68 out of 116, first round) and 75% thereafter. The final list included 33 topics, including logistical information, expectations for future health condition, complications, follow-up care, nutrition during treatment, and nutrition during recovery as topics with 100% agreement. Consensus on the source of support was reached for face-to-face contact, written information, information video, and a case manager. Conclusion. This study provides a list of important topics, from the perspectives of HCPs, to guide the systematic provision of education to support EC patients’ self-management during the preoperative phase. Additionally, the most preferred sources of support were face-to-face contact and a case manager.
