Gastrointestinal obstruction caused by solidification and coagulation of enteral nutrition: pathogenetic mechanisms and potential risk factors.

Enteral nutrition (EN) is preferred in order to provide nutrition and reduce catabolism in critically ill patients. Recent studies suggest that the use of EN is successful and complications are rare. However, an underestimated mechanical complication of tube feedings seen in critically ill patients is the coagulation and solidification of the EN causing gastrointestinal obstruction.

Novel endoscopic management for pancreatic pseudocyst with fistula to the common bile duct.

Pancreatic pseudocyst formation is a well-known complication of pancreatitis. It represents about 75% of the cystic lesions of the pancreas and might be located within or surrounding the pancreatic tissue. Sixty percent of the occurrences resolve spontaneously and only persistent, symptomatic or complicated cysts need to be treated.

Laparoscopic cyst fenestration in the treatment of polycystic liver disease.

Introduction: The PLD, included in the group of malformative lesions of ductal plate, is characterized by progressive development of multiple parenchymal cysts. Different surgical treatments have been proposed for symptomatic patients with PLD: percutaneus aspiration, fenestration, hepatic resection and liver transplantation. The aim of this report is to outline the treatment of polycystic liver disease with laparoscopic fenestration.

[Post-operative analgesia in case of ano-rectal diseases].

Background: The aim of the study was that to evaluate the post-operative pain in case of ano-rectal diseases wether treated by ketorolac, or buprenorphine or tramadol.

Materials And Methods: The intensity of post-operative pain was evaluated in 60 patients with hemorrhoidal diseases, fistulae, abscesses and anal neoplasms, divided into three homogenous groups and treated with intramuscular ketorolac (Group I), transdermal buprenorphine (Group II) and tramadol in elastomeric pump (Group III).

Results: The average index of the visual analogue scale, as mean to evaluate the intensity of the post-operative pain, was 1,85 in the first group, 1,20 in the second one and 1,40 in the third group.

[Skin neuroendocrine carcinoma metastasis: a case report].

Background: Merkel cell carcinoma (MCC) is a rare and aggressive skin tumour with a highly malignant nature whose appropriate treatment is still debated. The Authors report a case of cutaneous metastasis from neuroendocrine carcinoma and analyse new diagnostic and therapeutic options of neoplasms that occurs in sun-exposed areas.

Methods: The authors present the clinical, immunocytochemical characteristic of primary and secondary skin localization of a neuroendocrine tumor that affected a woman.
