Postoperative inflammatory response in patients with gastric cancer submitted to total and partial distal gastrectomy introduction: The removal of the stomach causes an acute inflammatory response. In some cases this response is exaggerated due to complications. The main purpose of this study was to describe the expected inflammatory response to gastrectomy. methods: This is a prospective analysis of consecutive patients submitted to gastrectomy for gastric cancer. For analytical purposes, the cohort was divided in complicated and uncomplicated patients. Uncomplicated patients were further divided in total gastrectomy and partial gastrectomy. The main outcome measure was to compare the inflammatory response of uncomplicated and complicated patients. The secondary outcome measure was to compare the inflammatory response of uncomplicated patients submitted to total and partial gastrectomy along the timeline. results: Preoperative values were similar between groups. At 24 h after gastrectomy, complicated patients showed significantly higher values for D-dimer, CRP and WBC. Further analysis comparing uncomplicated patients showed normal preoperative values and a mild elevation of inflammatory parameters which was similar in both groups of patients. conclusions: The expected systemic inflammatory response to partial or total gastrectomy was mild. Elevations of inflammatory values were shown early by complicated patients, constituting reliable parameters to identify postoperative inflammatory complications.
solid-pseudopapillary tumor of pancreas introduction:The solid-pseudopapillary tumor of pancreas (STP) is a low-grade malignant neoplasm. In Chile, 21 cases have been reported since 2008, most of them treated in Santiago. The present series contributes to the national case-load and has the purpose to describe the experience with this uncommon neoplasm in the IV Region. Patients and methods: From January 2004 to March 2014, a total of 38 benign and malignant pancreatic neoplasms have been informed in the data-base of our Regional Pathology Service. We selected the biopsies informed as STP and 5 cases (13%) were found. The clinical records of these patients were retrospectively reviewed. The results were reported using descriptive statistics with central tendency measures and dispersion. results: Most patients were women with a mean age of 44.8 years. All patients were studied with either abdominal ultrasound; computed tomography or magnetic resonance. In 2 patients the STP was located in the pancreatic tail, and they were submitted to distal pancreatectomy. The other 3 patients had the STP in the pancreatic head and were resolved by pancreatoduodenectomy. All tumors were confirmed by immunohistochemistry. Late follow-up showed malignant behavior in 1 patient while the other 4 patients are currently free of disease. conclusions: The general characteristics of STP in the IV Region are similar to what is currently known. They present a high incidence compared with the habitually published incidence.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
