Background: Gastric cancer (GC) treatment is largely determined by tumor stage. Despite improvements in the mode of treatment of various types of advanced disease, staging is still evolving. The role of tumor deposits (TDs) in staging remains debated. The purpose of this research is to investigate the relationship between TDs and prognosis in GC.Methods: A total of 3098 patients were considered eligible for prognostic analysis (2706 patients in the TDs-negative group and 392 patients in the TDs-positive group). A one-to-one propensity score-matching analysis was performed using a logistic regression mode and the following covariates: age, gender, tumor location, size, differentiation, perineural invasion, lymphovascular invasion, pTNM stage, type of gastrectomy, and the number of lymph nodes retrieved between TDs-negative and TDs-positive group, then 323 patients in each group were analyzed. Univariate and multivariate analyses of prognostic factors were conducted accordingly. The predictive ability of different staging system incorporating TDs was evaluated.Results: TDs were present in 14.5% cases and almost all of the patients (99%) suffered from advanced GC. Multivariate analysis showed that pN stage, chemotherapy, and TDs were the independent prognostic factors. The TDs-positive group showed a lower rate of 5-year disease-free survival compared with the TDs-negative group in all patients, stage II, and stage III patients (p = 0.001, 0.029, and 0.003, respectively). The 5-year disease-free survival for patients with TDs and without TDs was 27.6% and 34.4%, respectively.Conclusions: Our research shows that TDs are closely associated with prognosis in GC. TDs should be incorporated into the TNM staging system, which could then accurately improve the staging reliability and prognostic assessment. [ABSTRACT FROM AUTHOR]

Background: The possibility of lymph node metastasis (LNM) is critical to the assessment of the indication for endoscopic submucosal dissection. Thus, the aim of this study is to identify the risk factors for LNM and construct a risk-scoring model for patients with early gastric cancer to guide treatment.Methods: A retrospective examination of reports and studies carried out January 2000 and December 2014 was conducted. A risk-scoring model for predicting LNM was developed based on the data thus collected. In addition, the model is subject to verification and validation by three institutions.Results: Of the 1029 patients, 228 patients (22%) had LNM. Multivariate analysis showed that female, depressed type, undifferentiated type, submucosa, tumor size, and lymphovascular invasion were significantly associated with LNM. An 11-point risk-scoring model was used to predict LNM risk. An area under the receiver operating characteristic (AUROC) of the risk-scoring model was plotted using the development set and the AUROC of the model [0.76 (95% CI 0.73-0.80)] to predict LNM risk. After internal and external validation, the AUROC curve for predicting LNM was 0.77 (95% CI 0.68-0.86), 0.82 (95% CI 0.72-0.91), and 0.82 (95% CI 0.70-0.94), respectively.Conclusions: A risk-scoring model for predicting LNM was developed and validated. It could help with personalized care for patients with EGC. [ABSTRACT FROM AUTHOR]

Abstract: Anastomotic leakage of pancreaticojejunostomy is a common problem and a significant cause of morbidity and mortality after pancreatic resection. An appropriate technique to minimize pancreatic leakage is very important. Recently we have performed a safe and simple mesh-reinforced pancreaticojejunostomy, by which a strip of polypropylene mesh is wrapped around the pancreatic stump in order to secure the end-to-end pancreaticojejunal anastomosis. No leakage developed in all 10 patients who received this procedure. [Copyright &y& Elsevier]

Abstract: Postoperative ascites is a rare and serious complication of laparoscopic procedures. Urinary tract injury, bowel injury, and lymph duct injury are the common causes; however, in some patients no definitive cause can be identified after an extensive diagnostic work-up. We present a case of postoperative ascites of unknown origin. The patient recovered with general treatments. We presume that diffuse peritoneal injury may have been caused by unidentified substances in our patient. [Copyright &y& Elsevier]
