| 1 | Sentinel node navigation surgery in gastric cancer: Current status显示文摘The theory behind using sentinel node mapping and biopsy in gastric cancer surgery, the so-called sentinel node navigation surgery, is to limit the extent of surgi-cal tissue dissection around the affected organ and subsequently the accompanied morbidity. However, ob-stacles on the clinical correspondence of sentinel node navigation surgery in everyday practice have occasion-ally alleviated researchers' interest on the topic. Only recently with the widespread use of minimally invasive surgical techniques, i.e., laparoscopic gastric cancer resections, surgical community's interest on the topic have been unavoidably reflated. Double tracer methods appear superior compared to single tracer techniques. Ongoing research is now focused on the invention of new lymph node detection methods utilizing sophisti-cated technology such as infrared ray endoscopy, flo-rescence imaging and near-infrared technology. Despite its notable limitations, hematoxylin/eosin is still the mainstay staining for assessing the metastatic status of an identified lymph node. An intra-operatively verified metastatic sentinel lymph node will dictate the need for further conventional lymph node dissection. Thus, laparoscopic resection of the gastric primary tumor combined with the appropriate lymph node dissection as determined by the process of sentinel lymph node status characterization represents an option for early gastric cancer. Patients with T3 or more advanced dis-ease should still be managed conventionally with resec-tion plus standard lymph node dissection. | Dimitrios Symeonidis George Koukoulis Konstantinos Tepetes | 2014 | World Journal of Gastrointestinal Surgery2014，6，6： | 9 |
| 2 | colorectal 癌症阶段特征上的 antiplatelet 治疗的影响显示文摘 AIM:To evaluate whether antiplatelet medication leads to an earlier stage colorectal cancer(CRC) diagnosis.METHODS:From January 2002 until March 2010,patients that presented to our institution with the initial diagnosis of CRC and were submitted to an open curative CRC resection or a palliative procedure were retrospectively reviewed.Exclusion criteria were the use of antithrombotic medication,i.e.,coumarins,and appendiceal malignancies.Data acquired from medical files included age,gender,past medical history,antithrombotic treatment received prior to endoscopic diagnosis,preoperative imaging staging,location of the tumor,surgical and final histopathological report.Patients that did not receive any antithrombotic medication prior to the endoscopic diagnosis comprised the control group of the study,while patients that were on antiplatelet medication comprised the antiplatelet group.Primary end point was a comparison of CRC stage in the two groups of the study.CRC presenting symptoms and the incidence of each cancer stage in the two groups were also evaluated.RESULTS:A total of 387 patients with the diagnosis of CRC were submitted to our department for further surgical treatment.Ninety-eight patients(25.32%),with a median age of 71 years(range 52-91 years),were included in the antiplatelet group,while 289(74.67%) patients,with a median age of 67 years(range 4190 years),were not in any thrombosis prophylaxis medication(control group).Thirty-one patients were treated with some kind of palliative procedure,either endoscopic,such as endoscopic stent placement,or surgical,such as de-compressive colostomy or deviation.Coronary disease(77.55%-76 patients),stroke recurrence prevention(14.28%-14 patients) and peripheral arterial disease(8.16%-8 patients) were the indications for the administration of antiplatelet treatment(aspirin,clopidogrel,ticlopidine or dipyridamole) in the antiplatelet group.All patients on aspirin treatment received a dosage of 100 mg/d,while the minimum prophylactic dosages were also used for the rest of the antiplatelet drugs.Investigation of an iron deficiency anemia(147 patients),per rectum blood loss(84 patients),bowel obstruction and/or perforation(81 patients),bowel habits alterations(32 patients),nonspecific symptoms,such as weight loss,intermittent abdominal pain and fatigue,(22 patients) or population screening(21 patients) were the indications for the endoscopic investigation in both groups.Bleeding,either chronic presenting as anemia or acute was significantly higher(P = 0.002) for the antiplatelet arm of the study(71 patients-72.4% of the antiplatelet group vs 160 patients-55.3% of the control group).The mean tumor,node and metastasis stage was 2.57 ± 0.96 for the control group,2.27 ± 0.93 for the antiplatelet group(P = 0.007) and 2.19 ± 0.92 for the subgroup of patients taking aspirin(P = 0.003).The incidence of advanced disease(stage Ⅳ) was lower for the antiplatelet group of the study(P = 0.033).CONCLUSION:The adverse effect of bleeding that is justifiably attached to this drug category seems to have a favorable impact on the staging characteristics of CRC. | Dimitrios Symeonidis Georgios Koukoulis Grigorios Christodoulidis Ioannis Mamaloudis Ioannis Chatzinikolaou Konstantinos Tepetes | 2012 | World Journal of Gastrointestinal Endoscopy2012，4，9： | 3 |
| 3 | Effects of albumin/glutaraldehyde glue on healing of colonic anastomosis in rats显示文摘AIM To evaluate the effect of local surgical adhesive glue(albumin/glutaraldehyde-Bioglue) on the healing of colonic anastomoses in rats.METHODS Forty Albino-Wistar male rats were randomly divided into two groups, with two subgroups of ten animals each. In the control group, an end-to-end colonic anastomosis was performed after segmental resection. In the Bioglue group, the anastomosis was protected with extraluminar application of adhesive glue containing albumin and glutaraldehyde. Half of the rats were sacrificed on the fourth and the rest on the eighth postoperative day. Anastomoses were resected and macroscopically examined. Bursting pressures were calculated and histological features were graded. Other parameters of healing, such as hydroxyproline and collagenase concentrations, were evaluated. The experimental data were summarized and computed from the results of a one-way ANOVA. Fisher's exact test was applied to compare percentages. RESULTS Bursting pressures, adhesion formation, inflammatory cell infiltration, and collagen deposition were significantly higher on the fourth postoperative day in the albumin/glutaraldehyde group than in the control group. Furthermore, albumin/glutaraldehyde significantly increased adhesion formation, inflammatory cell infiltration, neoangiogenesis, and collagen deposition on the eighth postoperative day. There was no difference in fibroblast activity or hydroxyproline and collagenase concentrations. CONCLUSION Albumin/glutaraldehyde, when applied on colonic anastomoses, promotes their healing in rats. Therefore, the application of protective local agents in colonic anastomoses leads to better outcomes. | Kalliopi Despoudi Ioannis Mantzoros Orestis Ioannidis Aggeliki Cheva Nikolaos Antoniou Dimitrios Konstantaras Savvas Symeonidis Manousos George Pramateftakis Efstathios Kotidis Stamatis Angelopoulos Konstantinos Tsalis | 2017 | World Journal of Gastroenterology2017，23，31： | 0 |
| 4 | Platelet rich plasma effectiveness in bowel anastomoses:A systematic review显示文摘BACKGROUND Anastomotic leak constitutes a major problem in abdominal surgery.Technical insufficiency,topical or systemic factors contribute to disrupted healing of the performed bowel anastomosis and result in anastomosis leakage,with detrimental effects on patient postoperative outcomes.Despite the investigation of several factors and the invention of protective materials,the ideal agent to prevent anastomotic leaks is yet to be determined.AIM To study the effect of platelet rich plasma(PRP)on the healing of bowel anastomoses.METHODS A systematic literature search was performed in PubMed,EMBASE,and Scopus databases to identify studies investigating the effect of PRP application on bowel anastomosis.RESULTS Eighteen studies were eligible with a total population of 712 animals including rats(14 studies),rabbits(2 studies)and pigs(2 studies).No postoperative complications were reported following PRP application.Fourteen out of 18 studies reported a statistically significant higher anastomosis bursting pressure in PRP groups compared to control either in healthy animals or animal models with underlying condition or intervention,such as intraperitoneal chemotherapy or peritonitis.Similar results were reported by ten studies in terms of tissue hydroxyproline levels.One study reported significant increase in collagen deposition in PRP groups.PRP application resulted in significantly decreased inflammatory cell infiltration in the presence of peritonitis or intraperitoneal chemotherapy(6 studies).CONCLUSION The application of PRP is associated with improved bowel anastomosis outcomes,especially in animal models having an underlying condition affecting the normal healing process.PRP application seems to augment the normal healing process under these circumstances.However,further studies are needed to investigate the potential role of PRP on bowel anastomosis healing,especially in clinical settings. | Georgios Geropoulos Kyriakos Psarras Dimitrios Giannis Eirini Chrysovalantou Martzivanou Maria Papaioannou Christos Dimitrios Kakos Efstathios Theodoros Pavlidis Nikolaos Symeonidis Georgios Koliakos Theodoros Efstathios Pavlidis | 2021 | World Journal of Gastrointestinal Surgery2021，13，12： | 0 |
| 5 | Isoperistaltic vs antiperistaltic anastomosis after right hemicolectomy:A comprehensive review显示文摘To optimize the efficiency of ileocolic anastomosis following right hemicolectomy,several variations of the surgical technique have been tested.These include performing the anastomosis intra-or extracorporeally or performing a stapled or hand-sewn anastomosis.Among the least studied is the configuration of the two stumps(i.e.,isoperistaltic or antiperistaltic)in the case of a side-to-side anastomosis.The purpose of the present study is to compare the isoperistaltic and antiperistaltic side-to-side anastomotic configuration after right hemicolectomy by reviewing the relevant literature.High-quality literature is scarce,with only three studies directly comparing the two alternatives,and no study has revealed any significant differences in the incidence of anastomosis-related complications such as leakage,stenosis,or bleeding.However,there may be a trend towards an earlier recovery of intestinal function following antiperistaltic anastomosis.Finally,existing data do not identify a certain anastomotic configuration(i.e.,isoperistaltic or antiperistaltic)as superior over the other.Thus,the most appropriate approach is to master both anastomotic techniques and select between the two configurations based on each individual case scenario. | Dimitrios Symeonidis Kostas-Sotirios Karakantas Labrini Kissa Athina A Samara Effrosyni Bompou Konstantinos Tepetes Georgios Tzovaras | 2023 | World Journal of Clinical Cases2023，11，8： | 0 |
