    Background: Distal pancreatectomy with celiac axis resection (DP-CAR) is a treatment option for selected patients with pancreatic cancer involving the celiac axis. A recent multicenter European study reported a 90-day mortality rate of 16%, highlighting the importance of patient selection. The authors constructed a risk score to predict 90-day mortality and assessed oncologic outcomes. Methods: This multicenter retrospective cohort study investigated patients undergoing DP-CAR at 20 European centers from 12 countries (model design 2000-2016) and three very-high-volume international centers in the United States and Japan (model validation 2004-2017). The area under receiver operator curve (AUC) and calibration plots were used for validation of the 90-day mortality risk model. Secondary outcomes included resection margin status, adjuvant therapy, and survival. Results: For 191 DP-CAR patients, the 90-day mortality rate was 5.5% (95 confidence interval [CI], 2.2-11%) at 5 high-volume (1 DP-CAR/year) and 18% (95 CI, 9-30%) at 18 low-volume DP-CAR centers (P=0.015). A risk score with age, sex, body mass index (BMI), American Society of Anesthesiologists (ASA) score, multivisceral resection, open versus minimally invasive surgery, and low- versus high-volume center performed well in both the design and validation cohorts (AUC, 0.79 vs 0.74; P=0.642). For 174 patients with pancreatic ductal adenocarcinoma, the R0 resection rate was 60%, neoadjuvant and adjuvant therapies were applied for respectively 69% and 67% of the patients, and the median overall survival period was 19months (95 CI, 15-25months). Conclusions: When performed for selected patients at high-volume centers, DP-CAR is associated with acceptable 90-day mortality and overall survival. The authors propose a 90-day mortality risk score to improve patient selection and outcomes, with DP-CAR volume as the dominant predictor

    Open versus laparoscopically-assisted oesophagectomy for cancer: a multicentre randomised controlled phase III trial - the MIRO trial

    <p>Abstract</p> <p>Background</p> <p>Open transthoracic oesophagectomy is the standard treatment for infracarinal resectable oesophageal carcinomas, although it is associated with high mortality and morbidity rates of 2 to 10% and 30 to 50%, respectively, for both the abdominal and thoracic approaches. The worldwide popularity of laparoscopic techniques is based on promising results, including lower postoperative morbidity rates, which are related to the reduced postoperative trauma. We hypothesise that the laparoscopic abdominal approach (laparoscopic gastric mobilisation) in oesophageal cancer surgery will decrease the major postoperative complication rate due to the reduced surgical trauma.</p> <p>Methods/Design</p> <p>The MIRO trial is an open, controlled, prospective, randomised multicentre phase III trial. Patients in study arm A will receive laparoscopic-assisted oesophagectomy, i.e., a transthoracic oesophagectomy with two-field lymphadenectomy and laparoscopic gastric mobilisation. Patients in study arm B will receive the same procedure, but with the conventional open abdominal approach. The primary objective of the study is to evaluate the major postoperative 30-day morbidity. Secondary objectives are to assess the overall 30-day morbidity, 30-day mortality, 30-day pulmonary morbidity, disease-free survival, overall survival as well as quality of life and to perform medico-economic analysis. A total of 200 patients will be enrolled, and two safety analyses will be performed using 25 and 50 patients included in arm A.</p> <p>Discussion</p> <p>Postoperative morbidity remains high after oesophageal cancer surgery, especially due to major pulmonary complications, which are responsible for 50% of the postoperative deaths. This study represents the first randomised controlled phase III trial to evaluate the benefits of the minimally invasive approach with respect to the postoperative course and oncological outcomes in oesophageal cancer surgery.</p> <p>Trial Registration</p> <p><a href="http://www.clinicaltrials.gov/ct2/show/NCT00937456">NCT00937456</a> (ClinicalTrials.gov)</p

    Outcomes After Distal Pancreatectomy with Celiac Axis Resection for Pancreatic Cancer: A Pan-European Retrospective Cohort Study

    BACKGROUND: Western multicenter studies on distal pancreatectomy with celiac axis resection (DP-CAR), also known as the Appleby procedure, for locally advanced pancreatic cancer are lacking. We aimed to study overall survival, morbidity, mortality and the impact of preoperative hepatic artery embolization (PHAE). METHODS: Retrospective cohort study within the European-African Hepato-Pancreato-Biliary-Association, on DP-CAR between 1-1-2000 and 6-1-2016. Primary endpoint was overall survival. Secondary endpoints were radicality (R0-resection), 90-day mortality, major morbidity, and pancreatic fistulae (grade B/C). RESULTS: We included 68 patients from 20 hospitals in 12 countries. Postoperatively, 53% of patients had R0-resection, 25% major morbidity, 21% an ISGPS grade B/C pancreatic fistula, and 16% mortality. In total, 82% received (neo-)adjuvant chemotherapy and median overall survival in 62 patients with pancreatic ductal adenocarcinoma patients was 18 months (CI 10-37). We observed no impact of PHAE on ischemic complications. CONCLUSIONS: DP-CAR combined with chemotherapy for locally advanced pancreatic cancer is associated with acceptable overall survival. The 90-day mortality is too high and should be reduced. Future studies should investigate to what extent increasing surgical volume or better patient selection can improve outcomes

    L'hypertension portale (HTP) peut ĂȘtre responsable de complications vasculaires et hĂ©modynamiques dans le territoire splĂ©nique [splĂ©nomĂ©galie, hypersplĂ©nisme, anĂ©vrysme de l'artĂšre splĂ©nique, syndrome de l'artĂšre splĂ©nique, shunt splĂ©no-rĂ©nal (SSR)] qui peuvent justifier une prise en charge spĂ©cifique au cdurs d'une transplantation hĂ©patique (TH). Le but de ce travail Ă©tait (i) d'Ă©valuer diffĂ©rentes stratĂ©gies de dĂ©connexion des SSR [splĂ©nectomie (SP), ligature de la veine rĂ©nale gauche (LVR) et anastomose rĂ©no porte (ARP)] permettant d'assurer une revascularisation porte optimale du greffon hĂ©patique au cours d'une TH et (ii) d'Ă©valuer les rĂ©sultats de la splĂ©nectomie (quelle que soit son indication) en TH. Deux sĂ©ries rĂ©trospectives sont rapportĂ©es: 1/ De 1994 Ă  2012, 48 SP (dont 22 pour SSR) et 7 LVR pour SSR ont Ă©tĂ© rĂ©alisĂ©es Ă  la Croix-Rousse (Lyon). Les donnĂ©es peropĂ©ratoires d'un groupe de 709 patients transplantĂ©s mais sans SP pendant la mĂȘme pĂ©riode Ă©taient comparĂ©es au groupe avec SP (n=48). Les rĂ©sultats postopĂ©ratoires (TH avec SP) Ă©taient comparĂ©s aux donnĂ©es de la littĂ©rature (TH sans SP) ; 2/ De 1998 Ă  2012, 15 LVR et 17 ARP pour SSR ont Ă©tĂ© rĂ©alisĂ©es Ă  Paul Brousse (Paris). La SP, la LVR et l'ARP Ă©taient d'efficacitĂ© comparable pour la dĂ©connexion des SSR. AprĂšs SP, LVR et ARP, la survie Ă  3 mois et Ă  5 ans Ă©tait respectivement de 96%, 91% et 100o/o et de 83%, 60% et 79% (p=0,01). Les groupes ARP et LVR Ă©taient comparables sauf pour le taux de thrombose porte prĂ©opĂ©ratoire supĂ©rieur dans le groupe ARP (76% vs 27%). Les survies Ă©taient identiques (p=0,1) mais le risque d'insuffisance rĂ©nale temporaire post TH Ă©tait plus important aprĂšs ARP qu'aprĂšs LVR. En cas d'HTP modĂ©rĂ©e, la survie Ă©tait meilleure aprĂšs ARP qu'aprĂšs LVR (p=0,049). Chez les patients splĂ©nectomisĂ©s au cours de la TH, et par rapport aux patients transplantĂ©s sans SP, (i) le taux transfusionnel (+3 PGR), la durĂ©e opĂ©ratoire (+53 minutes) et la survenue d'une thrombose porte postopĂ©ratoire (35%) Ă©taient plus importants, (ii) la thrombopĂ©nie Ă©tait corrigĂ©e significativement plus rapidement, le taux de rejet Ă©tait moins important alors que le taux d'infections (prĂ©coces ou tardives) Ă©taient comparable. La dĂ©connexion des shunts splĂ©no-rĂ©naux associĂ©e Ă  la prise en charge d'une Ă©ventuelle thrombose porte permet d'obtenir des survies comparables Ă  celle des patients transplantĂ©s sans SSR. La SP traite efficacement toutes les complications splĂ©niques de l'HTP et, pour les SSR, reste une alternative possible Ă  l'ARP et Ă  la LVR malgrĂ© une morbiditĂ© pĂ©ri-opĂ©ratoire plus importante. La rĂ©alisation d'une LVR est Ă  discuter uniquement en prĂ©sence d'une HTP sĂ©vĂšre alors que l'ARP permet une excellente survie quel que soit le degrĂ© d'HTP et la permĂ©abilitĂ© de la veine porte avant la THLYON1-BU SantĂ© (693882101) / SudocSudocFranceF
