SARS-CoV-2 identified by transmission electron microscopy in lymphoproliferative and ischaemic intestinal lesions of COVID-19 patients with acute abdominal pain: two case reports.

Background: SARS-CoV-2 may produce intestinal symptoms that are generally mild, with a small percentage of patients developing more severe symptoms. The involvement of SARS-CoV-2 in the physiopathology of bowel damage is poorly known. Transmission electron microscopy (TEM) is a useful tool that provides an understanding of SARS-CoV-2 invasiveness, replication and dissemination in body cells but information outside the respiratory tract is very limited.

[Results after laparoscopic liver resection: an appropriate option in malignant disease].

Introduction: The laparoscopic approach is not yet widely used in liver surgery, but has proven to be safe and feasible in selected patients even in malignant disease. The experience and results of a hepato-pancreato-biliary (HPB) surgery unit in the treatment of malignant liver disease by laparoscopic approach is presented.

Material And Methods: Between February 2002 and May 2011, 71 laparoscopic liver resections were performed, 43 for malignant disease (only patients with more than one year of follow-up were included).
