This article has the general objective of estimating the efficiency of urban solid waste management in 940 Brazilian munici-palities through Data Envelopment Analysis(DEA)technique and has specific objectives:(i)to estimate efficiency scores;(ii)to compare the performance between different groups of municipalities;and(ii)to analyze the profile of efficient munici-palities from the perspective of the guidelines of Law 12,305/2010 and socio-economic and environmental *** technique used was DEA with output-oriented and variable scale to return *** results showed higher efficiency scores in the municipalities with populations above 500,000 *** score variation ranged from 0.5(municipalities with populations<10,000 inhabitants)to 0.9(municipalities with more than 500,000 inhabitants).Of the sample set,only 12.34%of the municipalities were considered efficient,and when analyzing the efficient group,it was found that adherence to legislation was not a major factor in achieving efficiency.

It is well known that radical intent surgery is,as of today,the only curative treatment available for perihilar cholangiocarcinoma(pCCA);the standard surgical procedure includes major hepatectomy with caudate lobe resection and extrahepatic bile duct resection(1).A recent paper set the benchmark values for pCCA surgery:in this paper,acceptable benchmark values for morbidity.
