In my SQL server database I have a field called observaciones_hechos(ntext,null).

  in SQL appear as text

I am creating a view from this database table in ArcMap and for some reason instead seeing the text in the table of content I just see blob 

How can I see the text instead blob in the view? Can I do that?

ntext is a legacy data type that has been deprecated:  ntext, text, and image (Transact-SQL) | Microsoft Docs 

Fixed and variable-length data types for storing large non-Unicode and Unicode character and binary data. Unicode data uses the UNICODE UCS-2 character set.

IMPORTANT!ntext, text, and image data types will be removed in a future version of SQL Server. Avoid using these data types in new development work, and plan to modify applications that currently use them. Use nvarchar(max), varchar(max), and varbinary(max)instead.

ntext isn't listed as supported in ArcGIS:  SQL Server data types supported in ArcGIS—Help | ArcGIS Desktop 

Looking back through documentation, it appears ntext hasn't been supported since ArcGIS 9.2 or 9.3.1.
