1Comprehensive and innovative techniques for livertransplantation in rats: A surgical guide显示文摘AIM: To investigate our learning curves of orthotopic liver transplantation (OLT) in rats and the most important factor for successful surgery. METHODS: We describe the surgical procedures for our rat OLT model, and determined the operator learning curves. The various factors that contributed to successful surgery were determined. The most important surgical factors were evaluated between successful and unsuccessful surgeries.RESULTS: Learning curve data indicated that 50 cases were required for operator training to start a study. Operative time, blood loss, warm ischemic time, anhepatic phase, unstable systemic hemodynamic state, and body temperature after surgery significantly affected surgery success by univariate analysis, while the anhepatic phase was the most critical factor for success by multivariate analysis. CONCLUSION: OLT in rats is the only liver transplantation model that provides clinically relevant and reliable results. Shortened anhepatic phase is key to success in this model.Tomohide Hori Justin H Nguyen Yasuhiro Ogura Toshiyuki Hata Shintaro Yagi Ann-Marie T Baine Norifumi Ohashi Christopher B Eckman Aimee R Herdt Hiroto Egawa Yasutsugu Takada Fumitaka Oike Seisuke Saka-moto Mureo Kasahara Kohei Ogawa Koichiro Hata Taku Iida Yukihide Yonekawa Lena Sibulesky Kagemasa Kuribayashi Takuma Kato Kanako Saito Mie Torii Naruhiko Sahara Naoko Kamo Tomoko Sahara Motohiko Yasutomi Shinji Uemoto 2010World Journal of Gastroenterology2010,16,25:14
2Clinical outcomes following salvage Gamma Knife radiosurgery for recurrent glioblastoma显示文摘Glioblastoma multiforme(GBM) is the most common malignant primary brain tumor with a survival prognosis of 14-16 mo for the highest functioning patients. Despite aggressive, multimodal upfront therapies, the majority of GBMs will recur in approximately six months. Salvage therapy options for recurrent GBM(r GBM) are an area of intense research. This study compares recent survival and quality of life outcomes following Gamma Knife radiosurgery(GKRS) salvage therapy. Following a Pub Med search for studies usingGKRS as salvage therapy for malignant gliomas, nine articles from 2005 to July 2013 were identified which evaluated rG BM treatment. In this review, we compare overall survival following diagnosis, overall survival following salvage treatment, progression-free survival, time to recurrence, local tumor control, and adverse radiation effects. This report discusses results for rG BM patient populations alone, not for mixed populations with other tumor histology grades. All nine studies reported median overall survival rates(from diagnosis, range:16.7-33.2 mo; from salvage, range:9-17.9 mo). Three studies identified median progression-free survival(range:4.6-14.9 mo). Two showed median time to recurrence of GBM. Two discussed local tumor control. Six studies reported adverse radiation effects(range:0%-46% of patients). The greatest survival advantages were seen in patients who received GKRS salvage along with other treatments, like resection or bevacizumab, suggesting that appropriately tailored multimodal therapy should be considered with each rG BM patient. However, there needs to be a randomized clinical trial to test GKRS for rG BM before the possibility of selection bias can be dismissed.Erik W Larson Halloran E Peterson Wayne T Lamoreaux Alexander R MacKay Robert K Fairbanks Jason A Call Jonathan D Carlson Benjamin C Ling John J Demakas Barton S Cooke Christopher M Lee 2014World Journal of Clinical Oncology2014,5,2:5
3Strong prognostic value of nodal and bone marrow micro-involvement in patients with pancreatic ductal carcinoma receiving no adjuvant chemotherapy显示文摘AIM: To study the prognostic value of adjuvant chemo-therapy in patients with pancreatic, ductal adenocar-cinoma.METHODS: Lymph nodes from 106 patients with resectable pancreatic ductal adenocarcinoma were systematically sampled. A total of 318 lymph nodes classified histopathologically as tumor-free were examined using sensitive immunohistochemical assays. Forty-three (41%) of the 106 patients were staged as pT1/2, 63 (59%) as pT3/4, 51 (48%) as pN0, and 55 (52%) as pN1. The study population included 59 (56%) patients exhibiting G1/2, and 47 (44%) patients with G3 tumors. Patients received no adjuvant chemo- or radiation therapy and were followed up for a median of 12 (range: 3.5 to 139) mo.RESULTS: Immunostaining with Ber-EP4 revealed nodal microinvolvement in lymph nodes classified as “tumor free” by conventional histopathology in 73 (69%) out of the 106 patients. Twenty-nine (57%)of 51 patients staged histopathologically as pN0 had nodal microinvolvement. The five-year survival probability for pN0-patients was 54% for those without nodal microinvolvement and 0% for those with nodal microinvolvement. Cox-regression modeling revealed the independent prognostic effect of nodal microinvolvement on recurrence-free (relative risk 2.92, P = 0.005) and overall (relative risk 2.49, P = 0.009) survival.CONCLUSION: The study reveals strong and independent prognostic significance of nodal microinvolvement in patients with pancreatic ductal adenocarcinoma who have received no adjuvant therapy. The addition of immunohistochemical findings to histopathology reports may help to improve risk stratification of patients with pancreatic cancer.Emre F Yekebas Dean Bogoevski Michael Bubenheim Bjrn-Christian Link Jussuf T Kaifi Robin Wachowiak Oliver Mann Asad Kutup Guellue Cataldegirmen Lars Wolfram Andreas Erbersdobler Christoph Klein Klaus Pantel Jakob R Izbicki 2006World Journal of Gastroenterology2006,12,40:3
4Laparoscopic esophagomyotomy for achalasia in children:Areview显示文摘Esophageal achalasia in children is rare but ultimately requires endoscopic or surgical treatment. Historically, Heller esophagomyotomy has been recommended as the treatment of choice. The refinement of minimally invasive techniques has shifted the trend of treatment toward laparoscopic Heller myotomy(LHM) in adults and children with achalasia. A review of the available literature on LHM performed in patients < 18 years of age was conducted. The pediatric LHM experience is limited to one multiinstitutional and several single-institutional retrospective studies. Available data suggest that LHM is safe and effective. There is a paucity of evidence on the need for and superiority of concurrent antireflux procedures. In addition, a more complete portrayal of complications and long-term(> 5 years) outcomes is needed. Due to the infrequency of achalasia in children, these characteristics are unlikely to be defined without collaboration between multiple pediatric surgery centers. The introduction of peroral endoscopic myotomy and single-incision techniques, continue the trend of innovative approaches that may eventually become the standard of care.T Kumar Pandian Nimesh D Naik Aodhnait S Fahy Arman Arghami David R Farley Michael B Ishitani Christopher R Moir 2016World Journal of Gastrointestinal Endoscopy2016,8,2:2
