Abstract
Background: Numerous procedures for reconstruction after total gastrectomy have been proposed in order to achieve the lowest postoperative morbidity. Roux-en-Y esojejunostomy is widely accepted as a standard reconstruction technique due to its simplicity and its satisfactory nutritional outcomes. The construction of a gastric pouch and the maintenance of the duodenal transit have been proposed to ameliorate the quality of life of patients with gastric cancer. The aim of this study is to assess the quality of life of patients with different types of reconstruction after total gastrectomy. Material and Method: A systematic literature search was performed in PubMed, Science Direct, Wiley Online, Springer Link, up to December 1, 2019. Only original articles published in English were included. Quality of life was measured using different instruments. Postoperative aspects of reflux oesophagitis, dumping syndrome, food intake and weight status were evaluated. Results: 15 studies were included in this research. Three techniques for restoring the digestive tract continuity were compared: Roux-en-Y eso-jejunostomy, jejunal interposition and gastric pouch construction. The statistical results of the included studies were evaluated in terms of quality of life or weight status. Conclusions: The length of the alimentary limb for prophylaxis of eso-jejunal reflux should be at least 50 cm, but not more than 60 cm for the prevention of malabsorption. The quality of life was significantly better in patients with gastric pouch. Maintaining the duodenal transit does not seem to bring any benefit in quality of life or weight status, even if this is a physiological way.

Abstract
Nasogastric tubes (NGTs) are important for feeding, stenting and decompression after gastrointestinal surgeries, particularly in the upper gastrointestinal tract. Resistance in the removal of a NGT is a rare surgical complication and may be due to a knot in the tube or a stitch anchoring the tube to an anastomosis. We report a 41-year-old male patient who was admitted to the King Faisal Specialist Hospital & Research Center, Riyadh, Saudi Arabia, in 2015 with stomach cancer. He underwent a radical total gastrectomy with a Roux-en-Y oesophagojejunostomy. One week after the surgery, removal of the NGT was attempted; however, this was very difficult and the proximal end of the tube was cut off as a temporary measure. Six weeks later, an upper gastrointestinal tract endoscopy revealed that the distal end of the NGT had been accidentally stitched to the Roux-en-Y oesophagojejunostomy. The stitch was removed and the rest of the NGT was successfully extracted using a snare.

Abstract
BACKGROUND ECCO essential requirements for quality cancer care (ERQCC) are checklists and explanations of organisation and actions that are necessary to give high-quality care to patients who have a specific type of cancer. They are written by European experts representing all disciplines involved in cancer care. ERQCC papers give oncology teams, patients, policymakers and managers an overview of the elements needed in any healthcare system to provide high quality of care throughout the patient journey. References are made to clinical guidelines and other resources where appropriate, and the focus is on care in Europe. OESOPHAGEAL AND GASTRIC ESSENTIAL REQUIREMENTS FOR QUALITY CARE CONCLUSION Taken together, the information presented in this paper provides a comprehensive description of the essential requirements for establishing a high-quality OG cancer service. The ERQCC expert group is aware that it is not possible to propose a 'one size fits all' system for all countries, but urges that access to multidisciplinary units or centres must be guaranteed for all those with OG cancer.

Immunotherapy in Advanced Gastric Cancer: An Overview of the Emerging Strategies.
Magalhães, H, Fontes-Sousa, M, Machado, M
Canadian journal of gastroenterology & hepatology. 2018;:2732408
Abstract
Gastric cancer (GC) remains a public health problem, being the fifth most common cancer worldwide. In the western countries, the majority of patients present with advanced disease. Additionally, 65 to 75% of patients treated with curative intent will relapse and develop systemic disease. In metastatic disease, systemic treatment still represents the state of the art, with less than a year of median overall survival. The new molecular classification of GC was published in 2014, identifying four distinct major subtypes of gastric cancer, and has encouraged the investigation of new and more personalized treatment strategies. This paper will review the current evidence of immunotherapy in advanced gastric cancer.

Abstract
BACKGROUND Survival rates after a total gastrectomy with adequate lymphadenectomy are improving, leading to a shift in outcomes of interest from survival to postoperative outcomes and symptoms. In this systematic review, we investigate gastrointestinal symptoms that occur after a gastrectomy in relation to exocrine pancreatic insufficiency and the effect of pancreatic exocrine enzyme supplementation on these symptoms. METHODS Online databases PubMed, Embase, and Cochrane Library were systematically searched in accordance with the PRISMA guidelines. Studies that researched gastrointestinal symptoms, exocrine pancreatic function, and enzyme supplementation were identified and assessed. RESULTS The search resulted in a total of 1,023 articles after exclusion of duplicates. After performing a thorough assessment, 4 studies were included for systematic review. Exocrine pancreatic insufficiency was investigated by 2 studies; the results showed a significant decrease of total exocrine pancreatic function of up to 76%. The other 2 studies investigated the effect of pancreatic enzyme supplementation and found minor improvement in fecal consistency and a decrease in high-degree steatorrhea. No differences in individual symptom scores were reported. CONCLUSION Gastrointestinal symptoms such as steatorrhea, bloating, and dumping syndrome may be related to exocrine pancreatic function, initiated by total gastrectomy. Treatment with pancreatic enzymes had a minor positive effect on patients. It should be noted that these studies were of a small sample size and low quality. New and larger RCTs are necessary to either prove or disprove the benefit of pancreatic enzyme replacement therapy in the treatment of the gastrointestinal symptoms after total gastrectomy.

Hepatectomy for liver metastases from gastric cancer: a systematic review.
Liao, YY, Peng, NF, Long, D, Yu, PC, Zhang, S, Zhong, JH, Li, LQ
BMC surgery. 2017;(1):14
Abstract
BACKGROUND Official guidelines recommend palliative treatments for patients with liver metastases from gastric cancer. However, many case series reported that hepatectomy for such cases is safe and effective. This systematic review compares the overall survival between hepatectomy and palliative therapy in patients with liver metastases from gastric cancer. METHODS Two independent reviewers performed a systematic search of literature in EMBASE and PubMed, updated until 26 October 2016. The Newcastle-Ottawa score for cohort studies was used for quality assessment of included studies. RESULTS A total of eight cohort studies involving 196 patients in the hepatectomy arm and 481 in the palliative arm were included. Median overall survival of patients in the two arms was 23.7 (range, 13.0 to 48.0) and 7.6 (range, 5.5 to 15.2), respectively. Median rates of overall survival of the two arms were 69, 40, 33 and 27, 8, 4% at 1, 2, and 3 years, respectively. Comparing with palliative therapy, hepatectomy was associated with significantly lower mortality at 1 year (odds ratio 0.17, P < 0.001) and 2 years (odds ratio 0.15, P < 0.001). Among the patients who underwent hepatectomy, Asian cohorts showed higher median rates of overall survival than Western cohorts at 1 year (76 vs. 60%), 2 years (47 vs. 30%) and 3 years (39 vs. 23%). CONCLUSIONS Hepatectomy in the management of liver metastases from gastric cancer can be considered effective. In the elective setting, hepatectomy provides a potential alternative to palliative therapy.

Abstract
OBJECTIVE To examine and quantify the potential dose-response relationship between green tea intake and the risk of gastric cancer. DESIGN We searched PubMed, EMBASE, Web of Science, CBM, CNKI and VIP up to December 2015 without language restrictions. SETTING A systematic review and dose-response meta-analysis of observational studies. SUBJECTS Five cohort studies and eight case-control studies. RESULTS Compared with the lowest level of green tea intake, the pooled relative risk (95 % CI) of gastric cancer was 1·05 (0·90, 1·21, I 2=20·3 %) for the cohort studies and the pooled OR (95 % CI) was 0·84 (0·74, 0·95, I 2=48·3 %) for the case-control studies. The pooled relative risk of gastric cancer was 0·79 (0·63, 0·97, I 2=63·8 %) for intake of 6 cups green tea/d, 0·59 (0·42, 0·82, I 2=1·0 %) for 25 years of green tea intake and 7·60 (1·67, 34·60, I 2=86·5 %) for drinking very hot green tea. CONCLUSIONS Drinking green tea has a certain preventive effect on reducing the risk of gastric cancer, particularly for long-term and high-dose consumption. Drinking too high-temperature green tea may increase the risk of gastric cancer, but it is still unclear whether high-temperature green tea is a risk factor for gastric cancer. Further studies should be performed to obtain more detailed results, including other gastric cancer risk factors such as smoking and alcohol consumption and the dose of the effective components in green tea, to provide more reliable evidence-based medical references for the relationship between green tea and gastric cancer.

Abstract
Sarcopenia is a complex syndrome characterized by progressive and generalized loss of skeletal muscle mass and strength. Malignancy is a major determinant of sarcopenia, and gastric cancer (GC) is among the most common causes of this phenomenon. As sarcopenia is a well-recognized poor prognostic feature in GC and has been associated with worse tolerance of surgical and medical treatments, members of the multidisciplinary team should be aware of the clinical relevance, pathogenic mechanisms, and potential treatments for this syndrome. The importance of sarcopenia is often underestimated in everyday practice and clinical trials, particularly among elderly or fragile patients. As treatment options are improving in all disease stages, deeper knowledge and greater attention to the metabolic balance in GC patients could further increase the benefit of novel therapeutic strategies and dramatically impact on quality of life. In this review, we describe the role of sarcopenia in different phases of GC progression. Our aim is to provide oncologists and surgeons dealing with GC patients with a useful tool for comprehensive assessment and timely management of this potentially life-threatening condition.

Absorption, metabolism and protective role of fruits and vegetables polyphenols against gastric cancer.
Metere, A, Giacomelli, L
European review for medical and pharmacological sciences. 2017;(24):5850-5858
Abstract
Growing evidence links free radicals to the aging processes, degenerative diseases and cancer, underlying the important role played by some antioxidants, as polyphenols, present in fruits and vegetables, which seem able to counteract the toxic effects induced by oxidative stress. The gastrointestinal tract is continuously exposed to oxidant and antioxidant substances and, in particular in this district, the food rich in antioxidants could exert a protective effect against the risk of cancer. Polyphenols have a direct protective effect on the gastrointestinal tract, detoxifying the Reactive Oxygen Species (ROS) and Reactive Nitrogen Species (RNS), preserving antioxidant proteins and complexing metals. Although polyphenols are a class of antioxidant largely represented in vegetables and fruits, we are still uncertain whether the beneficial effects of a diet rich in plant products, are mainly due to these compounds. Our knowledge does not allow to be sure about which antioxidants are capable of having therapeutic effects, through which mechanism, the exact therapeutic dose or how long they have to be taken to have a significant protective effect. In this review we take into account the most common antioxidants, usually found in the diet and the processes regulating their absorption, metabolism and excretion, in order to elucidate the mechanism that could be responsible for the protection against cancer.
