Preoperative hepatic artery embolization before distal pancreatectomy plus celiac axis resection does not improve surgical results: A Spanish multicentre study.

BACKGROUND: Distal pancreatectomy with celiac axis resection (DP-CAR) is a surgical procedure with high morbidity and mortality performed in patients with locally advanced pancreatic cancer. Preoperative embolization of hepatic artery (PHAE) has been postulated as a technical option to increase resection rate. OBJECTIVE: comparison of morbidity and mortality at 90 days, operative time, hospital stay and survival between patients that performed DP-CAR with and without PHAE. METHODS: Observational retrospective multicentre study. INCLUSION CRITERIA: patient operated in Spanish centers with DP-CAR for pancreatic cancer from April 2004 until 23 June 2018. Preoperative (PHAE, neodjuvant treatment), intraoperative (operative time and blood loss) and postoperative data (morbidity, hospital stay, R0 and survival) were studied. Complications were measured with Clavien classification at 90 days. Specific pancreatic complications were measured using ISGPS classifications. Data were analyzed using R version 3.1.3 (http://www.r-project.org). Level of significance was set at 0.05. RESULTS: 41 patients were studied. 26 patients were not embolized (NO-PHAE group) and 15 patients received PHAE. Preoperative BMI and percentage of neoadjuvant chemotherapy were the only preoperative variables different between both groups. The operative time in the PHAE group was shorter (343 min) than in the non-PHAE group (411 min) (p < 0.06). Major morbidity (Clavien > IIIa) and mortality at 90 days were higher in the PHAE group than in the non-PHAE group (60% vs 23% and 26.6% vs 11.6% respectively) (p < 0.004). No statistical difference in overall survival was observed between both groups (p = 0.14). CONCLUSION: In our study PHAE is not related with less postoperative morbidity. Even more, major morbidity (Clavien III-IV) and mortality was higher in PHAE group.

Liver Transplantation: Analysis of Preservation Solutions in the Andalusian Registry.

BACKGROUND: The initial objective of this study is to analyze the impact on survival of the preservation solution used. Secondarily, the influence of donor age, underlying pathology, and graft ischemia time is investigated. METHODS: A multicenter retrospective analytical observational study has been carried out. A population of 1822 liver transplant recipients is studied in 4 Andalusian hospitals between 1995 and 2014. Survival of the patient and graft is analyzed by groups based on the conservation solution used, the age of the donor, the pathology indicated for transplant and the ischemia time, and the relationship between the variables through a bivariate study. A descriptive and predictive multivariate analysis of the variables was performed. RESULTS: Comparison of the graft and patient survival functions for each preservation solution did not differ significantly. The bivariate analysis shows a significantly higher utilization of Celsior and histidine-tryptophan-ketoglutarate solution in graft loss. The comparison between donor age groups showed significant differences in favor of donor grafts younger than 50 years. In the multivariate analysis of patient and graft survival, the donor age obtained a hazard ratio of 1.008 (P < .005) with donors older than 47.6 and 47.5 years, respectively. CONCLUSIONS: Survival analysis between pathology groups found significant differences, not obtaining predictive power for patient or graft survival in the multivariate study. No significant differences were found in survival according to ischemia time, but there was a relationship between early graft loss and longer mean cold ischemia times up to 18 hours.

[Surgical treatment of liver metastases from breast cancer]. / Tratamiento quirúrgico de las metástasis hepáticas de cáncer de mama.

INTRODUCTION: A small number of patients with breast cancer develop liver metastases (LM) as the sole site of regional dissemination. In these patients, surgical resection seems to be the best therapeutic option. We present our experience of LM from breast cancer and discuss the indications for resection. MATERIAL AND METHODS: Between July 2003 and March 2005, we performed five hepatectomies for LM from breast cancer. The mean age was 51 years (range: 38-66). Patients received diverse combinations of chemotherapy, hormone therapy and radiotherapy after mastectomy. The disease-free interval between mastectomy and diagnosis of LM was 61 months (range: 36-80). The number of LM was 1.83 (range: 1-6) with a median of one LM. The mean size was 4.1 cm (range: 1.5-6). RESULTS: Surgery consisted of segmentectomy (three patients), bisegmentectomy (one patient), right hepatectomy associated with isolated metasectomies of the left lobe and hilar lymphadenectomy (one patient). Operative mortality was 0%. Morbidity was 20% (one patient). The mean length of hospital stay was 8 days. The mean length of follow-up was 11.4 months (range: 3-21). The mean survival was 11.4 months (range: 3-21). Disease-free survival was 9.6 months (range: 3-21). Two patients have had recurrence (one local and one regional). CONCLUSIONS: Given its characteristics, LM from breast cancer is an infrequent indication for liver resection and should be performed whenever technically feasible, whenever R0 resection can be achieved, and when there is low operative risk. Postoperative survival is better with resection than with any other therapeutic modality, even though the period of disease-free survival is short.
