1皮肤神经鞘粘液瘤显示文摘皮肤神经鞘粘液瘤是近年来提出的较少见的良性软组织肿瘤。为了探讨该病的病变特点,我们报告18例并进行组织病理学、免疫组织化学观察及临床随访。结果示本病主要见于青少年,皮损常位于上肢和面部。组织病理学为一位于真皮和皮下的多结节状粘液性病变,丰富的粘液背景上分布梭形和星形的肿瘤细胞,似神经的环层小体。绝大部分病例S100蛋白为强阳性,支持其为神经鞘起源。有随访结果者无一复发。我们认为本病是一具有特征性病理变化的皮肤神经源性肿瘤,在一系列的命名中,我们认为以神经鞘粘液瘤为佳,能较准确地概括其主要病理变化。该病呈良性经过,局部手术切除即可获较好的治疗效果。范钦和 Alen P.W. 1996中华皮肤科杂志1996,29,4:14
2Endoclips vs large or small-volume epinephrine in peptic ulcer recurrent bleeding显示文摘AIM:To compare the recurrent bleeding after endoscopic injection of different epinephrine volumes with hemoclips in patients with bleeding peptic ulcer.METHODS:Between January 2005 and December 2009,150 patients with gastric or duodenal bleeding ulcer with major stigmata of hemorrhage and nonbleeding visible vessel in an ulcer bed(Forrest Ⅱa) were included in the study.Patients were randomized to receive a small-volume epinephrine group(15 to 25 mL injection group;Group 1,n = 50),a large-volume epinephrine group(30 to 40 mL injection group;Group 2,n = 50) and a hemoclip group(Group 3,n = 50).The rate of recurrent bleeding,as the primary outcome,was compared between the groups of patients included in the study.Secondary outcomes compared between the groups were primary hemostasis rate,permanent hemostasis,need for emergency surgery,30 d mortality,bleeding-related deaths,length of hospital stay and transfusion requirements.RESULTS:Initial hemostasis was obtained in all patients.The rate of early recurrent bleeding was 30%(15/50) in the small-volume epinephrine group(Group 1) and 16%(8/50) in the large-volume epinephrine group(Group 2)(P = 0.09).The rate of recurrent bleeding was 4%(2/50) in the hemoclip group(Group 3);the difference was statistically significant with regard to patients treated with either small-volume or large-volume epinephrine solution(P = 0.0005 and P = 0.045,respectively).Duration of hospital stay was significantly shorter among patients treated with hemoclips than among patients treated with epinephrine whereas there were no differences in transfusion requirement or even 30 d mortality between the groups.CONCLUSION:Endoclip is superior to both small and large volume injection of epinephrine in the prevention of recurrent bleeding in patients with peptic ulcer.Neven Ljubicic Ivan Budimir Alen Biscanin Marko Nikolic Vladimir Supanc Davor Hrabar Tajana Pavic 2012World Journal of Gastroenterology2012,18,18:11
3Scoring systems for peptic ulcer bleeding: which one to use?显示文摘AIM To compare the Glasgow-Blatchford score(GBS), Rockall score(RS) and Baylor bleeding score(BBS) in predicting clinical outcomes and need for interventions in patients with bleeding peptic ulcers. METHODS Between January 2008 and December 2013, 1012consecutive patients admitted with peptic ulcer bleeding(PUB) were prospectively followed. The pre-endoscopic RS, BBS and GBS, as well as the post-endoscopic diagnostic scores(RS and BBS) were calculated for all patients according to their urgent upper endoscopy findings. Area under the receiver-operating characteristics(AUROC) curves were calculated for the prediction of lethal outcome, rebleeding, needs for blood transfusion and/or surgical intervention, and the optimal cutoff values were evaluated.RESULTS PUB accounted for 41.9% of all upper gastrointestinal tract bleeding, 5.2% patients died and 5.4% patients underwent surgery. By comparing the AUROC curves of the aforementioned pre-endoscopic scores, the RS best predicted lethal outcome(AUROC 0.82 vs 0.67 vs0.63, respectively), but the GBS best predicted need for hospital-based intervention or 30-d mortality(AUROC0.84 vs 0.57 vs 0.64), rebleeding(AUROC 0.75 vs 0.61 vs 0.53), need for blood transfusion(AUROC 0.83 vs0.63 vs 0.58) and surgical intervention(0.82 vs 0.63 vs 0.52) The post-endoscopic RS was also better than the post-endoscopic BBS in predicting lethal outcome(AUROC 0.82 vs 0.69, respectively).CONCLUSION The RS is the best predictor of mortality and the GBS is the best predictor of rebleeding, need for blood transfusion and/or surgical intervention in patients with PUB. There is no one 'perfect score' and we suggest that these two tests be used concomitantly.Ivan Budimir Sanja Stojsavljevic Neven Barsic Alen Biscanin Gorana Mirosevic Sven Bohnec Lora Stanka Kirigin Tajana Pavic Neven Ljubicic 2017World Journal of Gastroenterology2017,23,41:6

5Biliary leakage after urgent cholecystectomy: Optimization of endoscopic treatment显示文摘AIM: To investigate the results of endoscopic treatment of postoperative biliary leakage occurring after urgent cholecystectomy with a long-term follow-up.METHODS: This is an observational database study conducted in a tertiary care center. All consecutive patients who underwent endoscopic retrograde cholangiography(ERC) for presumed postoperative biliary leakage after urgent cholecystectomy in the period between April 2008 and April 2013 were considered for this study. Patients with bile duct transection and biliary strictures were excluded. Biliary leakage was suspected in the case of bile appearance from either percutaneous drainage of abdominal collection or abdominal drain placed at the time of cholecystectomy. Procedural and main clinical characteristics of all consecutive patients with postoperative biliary leakage after urgent cholecystectomy, such as indication for cholecystectomy, etiology and type of leakage, ERC findings and post-ERC complications, were collected from our electronic database. All patients in whom the leakage was successfully treated endoscopically were followed-up after they were discharged from the hospital and the main clinical characteristics, laboratory data and common bile duct diameter were electronically recorded. RESULTS: During a five-year period, biliary leakage was recognized in 2.2% of patients who underwent urgent cholecystectomy. The median time from cholecystectomy to ERC was 6 d(interquartile range, 4-11 d). Endoscopic interventions to manage biliary leakage included biliary stent insertion with or without biliary sphincterotomy. In 23(77%) patients after first endoscopic treatment bile flow through existing surgical drain ceased within 11 d following biliary therapeutic endoscopy(median, 4 d; interquartile range, 2-8 d). In those patients repeat ERC was not performed andthe biliary stent was removed on gastroscopy. In seven(23%) patients repeat ERC was done within one to fourth week after their first ERC, depending on the extent of the biliary leakage. In two of those patients common bile duct stone was recognized and removed. Three of those seven patients had more complicated clinical course and they were referred to surgery and were excluded from long-term follow-up. The median interval from endoscopic placement of biliary stent to demonstration of resolution of bile leakage for ERC treated patients was 32 d(interquartile range, 28-43 d). Among the patients included in the follow-up(median 30.5 mo, range 7-59 mo), four patients(14.8%) died of severe underlying comorbid illnesses.CONCLUSION: Our results demonstrate the great efficiency of the endoscopic therapy in the treatment of the patients with biliary leakage after urgent cholecystectomy.Neven Ljubii Alen Bianin Tajana Pavi Marko Nikoli Ivan Budimir August Miji Ana Duzel 2015World Journal of Gastrointestinal Endoscopy2015,7,5:3
6Esophagogastric anastomosis in rats: Improved healing by BPC 157 and L-arginine, aggravated by L-NAME显示文摘AIM To cure typically life-threatening esophagogastric anastomosis in rats, lacking anastomosis healing and sphincter function rescue, in particular. METHODS Because we assume esophagogastric fistulas represent a particular NO-system disability, we attempt to identify the benefits of anti-ulcer stable gastric pentadecapeptide BPC 157, which was in trials for ulcerative colitis and currently for multiple sclerosis, in rats with esophagocutaneous fistulas. Previously, BPC 157 therapies have promoted the healing of intestinal anastomosis and fistulas, and esophagitis and gastric lesions, along with rescued sphincter function. Additionally, BPC 157 particularly interacts with the NOsystem. In the 4 d after esophagogastric anastomosis creation, rats received medication(/kg intraperitoneallyonce daily: BPC 157(10 μg, 10 ng), L-NAME(5 mg), or L-arginine(100 mg) alone and/or combined or BPC 157(10 μg, 10 ng) in drinking water). For rats underwent esophagogastric anastomosis, daily assessment included progressive stomach damage(sum of the longest diameters, mm), esophagitis(scored 0-5), weak anastomosis(m L H2 O before leak), low pressure in esophagus at anastomosis and in the pyloric sphincter(cm H2O), progressive weight loss(g) and mortality. Immediate effect assessed blood vessels disappearance(scored 0-5) at the stomach surface immediately after anastomosis creation. RESULTS BPC 157(all regimens) fully counteracted the perilous disease course from the very beginning(i.e., with the BPC 157 bath, blood vessels remained present at the gastric surface after anastomosis creation) and eliminated mortality. Additionally, BPC 157 treatment in combination with L-NAME nullified any effect of L-NAME that otherwise intensified the regular course. Consistently, with worsening(with L-NAME administration) and amelioration(with L-arginine), either L-arginine amelioration prevails(attenuated esophageal and gastric lesions) or they counteract each other(L-NAME + L-arginine); with the addition of BPC 157(L-NAME + L-arginine + BPC 157), there was a marked beneficial effect. BPC 157 treatment for esophagogastric anastomosis, along with NOS-blocker L-NAME and/or NOS substrate L-arginine, demonstrated an innate NO-system disability(as observed with L-arginine effectiveness). BPC 157 distinctively affected corresponding events: worsening(obtained with L-NAME administration that was counteracted); or amelioration(L-arginine + BPC 157-rats correspond to BPC 157-rats).CONCLUSION Innate NO-system disability for esophagogastric anastomoses, including L-NAME-worsening, suggests that these effects could be corrected by L-arginine and almost completely eliminated by BPC 157 therapy.Zeljko Djakovic Ivka Djakovic Vedran Cesarec Goran Madzarac Tomislav Becejac Goran Zukanovic Domagoj Drmic Lovorka Batelja Anita Zenko Sever Danijela Kolenc Alen Pajtak Nikica Knez Mladen Japjec Kresimir Luetic Dinko Stancic-Rokotov Sven Seiwerth Predrag Sikiric 2016World Journal of Gastroenterology2016,22,41:3
