Gastric cancer remains a significant health problem worldwide and surgery is currently the only potentially curative treatment option. Gastric cancer surgery is generally considered to be high risk ...surgery and fiveyear survival rates are poor,therefore a continuous strive to improve outcomes for these patients is warranted. Fortunately,in the last decades several potential advances have been introduced that intervene at various stages of the treatment process. This review provides an overview of methods implemented in pre-,intra- and postoperative stage of gastric cancer surgery to improve outcome. Better preoperative risk assessment using comorbidity index(e.g.,Charlson comorbidity index),assessment of nutritional status(e.g.,short nutritional assessment questionnaire,nutritional risk screening- 2002) and frailty assessment(Groningen frailty indicator,Edmonton frail scale,Hopkins frailty) was introduced. Also preoperative optimization of patients using prehabilitation has future potential.Implementation of fast-track or enhanced recovery after surgery programs is showing promising results,although future studies have to determine what the exact optimal strategy is.Introduction of laparoscopic surgery has shown improvement of results as well as optimization of lymph node dissection.Hyperthermic intraperitoneal chemotherapy has not shown to be beneficial in peritoneal metastatic disease thus far.Advances in postoperative care include optimal timing of oral diet,which has been shown to reduce hospital stay.In general,hospital volume,i.e.,centralization,and clinical audits might further improve the outcome in gastric cancer surgery.In conclusion,progress has been made in improving the surgical treatment of gastric cancer.However,gastric cancer treatment is high risk surgery and many areas for future research remain.
For gastric cancer patients, surgical resection with en-bloc lymphadenectomy is the cornerstone of curative treatment. Open gastrectomy has long been the preferred surgical approach worldwide. ...However, this procedure is associated with considerable morbidity. Several meta-analyses have shown an advantage in short-term outcomes of laparoscopic gastrectomy compared to open procedures, with similar oncologic outcomes. However, it remains unclear whether the results of these Asian studies can be extrapolated to the Western population. In this trial from the Netherlands, patients with resectable gastric cancer will be randomized to laparoscopic or open gastrectomy.
The study is a non-blinded, multicenter, prospectively randomized controlled superiority trial. Patients (≥18 years) with histologically proven, surgically resectable (cT1-4a, N0-3b, M0) gastric adenocarcinoma and European Clinical Oncology Group performance status 0, 1 or 2 are eligible to participate in the study after obtaining informed consent. Patients (n = 210) will be included in one of the ten participating Dutch centers and are randomized to either laparoscopic or open gastrectomy. The primary outcome is postoperative hospital stay (days). Secondary outcome parameters include postoperative morbidity and mortality, oncologic outcomes, readmissions, quality of life and cost-effectiveness.
In this randomized controlled trial laparoscopic and open gastrectomy are compared in patients with resectable gastric cancer. It is expected that laparoscopic gastrectomy will result in a faster recovery of the patient and a shorter hospital stay. Secondly, it is expected that laparoscopic gastrectomy will be associated with a lower postoperative morbidity, less readmissions, higher cost-effectiveness, better postoperative quality of life, but with similar mortality and oncologic outcomes, compared to open gastrectomy. The study started on 1 December 2014. Inclusion and follow-up will take 3 and 5 years respectively. Short-term results will be analyzed and published after discharge of the last randomized patient.

Postoperative ileus (POI) is a well-known complication of abdominal surgery and is considered to be caused by a local inflammation in the gut. Previously it has been shown that both local and ...systemic inflammation can be reduced by stimulation of the autonomic nervous system via lipid rich nutrition. Stimulation of the autonomic nervous system releases acetylcholine from efferent vagal nerve endings that binds to nicotinic receptors located on the inflammatory cells leading to a decrease of pro-inflammatory mediators. Besides administration of nutrition there are other ways of stimulating the autonomic nervous system such as gum chewing.
This prospective, placebo-controlled randomized trial will include 120 patients undergoing colorectal surgery which are randomized for gum chewing preoperatively and in the direct postoperative phase or a placebo. Postoperative ileus will be assessed both clinically by time to first flatus and time to first defecation and by determination of gastric motility using ultrasound to measure dimensions of the antrum. Furthermore the inflammatory response is quantified by analyzing pro-inflammatory mediators. Finally, markers of gut barrier integrity will be measured as well as occurrence of postoperative complications.
We hypothesize that chewing gum preoperatively and in the direct postoperative phase in patients undergoing colorectal surgery dampens local and systematic inflammation, via activation of the autonomic nervous system. Down-regulation of the inflammatory cascade via stimulation of the vagus nerve will ameleriote POI and enhance postoperative recovery.

Complications can be classified using the most-severe Clavien-Dindo-Classification (CDC) per patient or the total complication burden per patient expressed in the Comprehensive Complication Index ...(CCI). This study determined the additional value of CCI to CDC in examining the impact of complications after gastric cancer surgery.
The CCI and CDC were determined in the multicenter randomized LOGICA-trial comparing laparoscopic versus open D2-gastrectomy for cancer (cT1-4aN0-3M0). Differences in median CCI between laparoscopic and open gastrectomy were compared for overall postoperative complications and cardiovascular, gastrointestinal, infectious, pulmonary, and other complications. CCI and CDC were correlated to hospitalization, ICU-stay and reoperations using Spearman's rho-test and compared with standard Fisher's z-transformation.
Between 2015 and 2018, 211 patients underwent laparoscopic (n = 106) or open (n = 105) D2-gastrectomy, and 157 (74%) received neoadjuvant chemotherapy. Median CCI was comparable between laparoscopic versus open gastrectomy regarding overall complications (CCI 0 IQR 0-23.5 versus 0 IQR 0-22.6; p = 0.755) and subgroups of complications (p > 0.05). Both CCI and CDC showed moderate positive correlations for hospitalization (r
= 0.646 versus r
= 0.628; p = 0.001, difference clinically irrelevant), and reoperations (r
= 0.590 versus r
= 0.599; p = 0.070), and weak correlations for ICU-stay (r
= 0.446 versus r
= 0.440; p = 0.189).
The CCI is a composite scoring system based on the CDC and reflects a subjective interpretation of complication burden from the perspectives of both physicians and patients, following abdominal surgery other than gastrectomy. Implementing CCI showed no clinically relevant benefit and caused additional workload compared to CDC for assessing complication burden. Therefore, using the CCI alongside the CDC after gastric cancer surgery is not recommended.
Double-lumen tubes (DLT) and endobronchial blockers (EB) are used for one-lung ventilation in thoracic surgery. More complications are seen when using DLT when compared to EB, while major ...complications are rarely seen.

Quality of gastric cancer surgery is crucial for favorable prognosis. Generally, prospective trials lack quality control measures. This study assessed surgical quality and a novel D2-lymphadenectomy ...photo-scoring in the LOGICA-trial.
The multicenter LOGICA-trial randomized laparoscopic versus open total/distal D2-gastrectomy for resectable gastric cancer (cT1-4aN0-3M0) in 10 Dutch hospitals. During the trial, two reviewers prospectively analyzed intraoperative photographs of dissected nodal stations for quality control, and provided centers weekly feedback on their D2-lymphadenectomy, as continuous quality-enhancing incentive. After the trial, these photographs were reanalyzed to develop a photo-scoring for future trials, rating the D2-lymphadenectomy dissection quality (optimal-good-suboptimal-unevaluable). Interobserver variability was calculated (weighted kappa). Regression analyses related the photo-scoring to nodal yield, recurrence and 5-years survival.
Between 2015 and 2018, 212 patients underwent total/distal D2-gastrectomy (n = 122/n = 90), and 158 (75%) received neoadjuvant chemotherapy. R0-resection rate was 95%. Rate of ≥15 retrieved lymph nodes was 95%. Moderate agreement was obtained in stations 8 + 9 (κ = 0.522), 11p/11d (κ = 0.446) and 12a (κ = 0.441). Consensus was reached for discordant cases (30%). Stations 8 + 9, 11p/11d and 12a were rated ‘optimal’ in 76%, 63% and 68%. Laparoscopic photographs could be rated better than open (2% versus 12% ‘unevaluable’; 73% versus 50% ‘optimal’; p = 0.042). The photo-scoring did not show associations with nodal yield (p = 0.214), recurrence (p = 0.406) and survival (p = 0.988).
High radicality and nodal yield demonstrated good quality of D2-gastrectomy. The prospective quality control probably contributed to this. The photo-scoring did not show good performance, but can be refined. Laparoscopic D2-gastrectomy was better suited for standardized surgical photo-evaluation than open surgery.
The aim of this study is to provide data on long term results of gastric cancer surgery and in particular the D1 gastric resection.
In the period 1992-2004, 235 male and female patients with a median ...age of 69 and 70 years respectively, were included with a stage I through IV gastric carcinoma, of which 37% was stage IV disease. Whenever possible a gastric resection was performed. In case of obstructive tumour growth palliation was provided by means of a gastro-enterostomy.
Gastrectomy with curative intent was achieved in 50%, palliative resection in 22%, palliative surgery (gastro-enterostomy) in 10% and in 18% irresectability led to surgical exploration only. Patients in the curative intent group demonstrated a 47% survival after 5 years and up to 34% after 10 years. However metastases where seen in 32% of the patients after gastrectomy with curative intent. After palliative resection one year survival was 57%, whereas 19% survived more than 3 years. Overall postoperative morbidity and mortality rates were 40% and 13% respectively.
Long term survival after surgery for gastric cancer is poor and is improved by early detection and radical resection. However, palliative resection showed improved survival compared to gastro-enterostomy alone or no resection at all which may be an effect of adjuvant therapy.

The association between nutritional depletion and the increased susceptibility for infectious diseases has been recognized for a long time. The complexity of the immune system, however, makes it ...difficult to unravel the underlying mechanisms. It appears that depletion adversely affects virtually all components of the immune system. This review provides an overview over the specific requirements of substrates by immune cells and the effects of nutritional depletion on various components of the immune response, with special attention to gut‐associated lymphoid tissue. The literature concerning effects of dietary interventions with specific nutrients on the immune response is also discussed. Finally, we offer a hypothesis with regard to the improvement of composition of “trauma” nutrition solutions.
