CVS clarifies the relations of the anatomic structures that should be divided, and therefore, it should be ideally and routinely applied in all LCs because of its highly protective role against bile duct injuries.

Liver cystadenomas can be easily misdiagnosed with other hepatic cystic lesions. An aggressive surgical approach is recommended, due to their malignant potential and high recurrence rate after fenestration.

Gastrointestinal stromal tumors (GIST) are uncommon mesenchymal spindle-cell or epithelioid neoplasms, located mainly with higher frequency in the stomach and small bowel. GISTs represent the majority of primary non-epithelial neoplasms of the digestive tract, most frequently expressing the KIT protein a transmembrane tyrosine kinase receptor for stem cell factor. Extra-gastrointestinal stromal tumors tend to present In fewer than 5% of cases; they originate primarily from the mesentery, omentum or peritoneum. Furthermore, these extra-gastrointestinal tumors (EGIST) tend to be more common in patients over the age of 50 years. EGISTs are neoplasms with overlapping immunohistological features, occurring in the abdomen outside the gastrointestinal tract with no connection to the gastric or intestinal wall. We describe here a rare case of EGIST of the lesser omentum and report the clinical, macroscopic, immunohistological and radiological features of an EGIST arising in the lesser omentum of a 63-year old man. Clinical course and the prognostic factors of such lesions will also be discussed. EGISTs in the lesser omentum can grow slowly and remain silent despite a large tumor size. In most cases, a pre-operative diagnosis is not possible, and the patient undergoes a surgical operation for the generic diagnosis of abdominal mass. During the intervention it is important to achieve a complete removal of the mass and to examine every possible adhesion to the gastrointestinal wall.

The incidence of DGE in high-volume centers specialized in pancreatic surgery is well below 20%, thus following the improved rates that have been reported in the last decade regarding mortality and length of hospital stay after pancreatic surgery. DGE mandates a uniform definition and method of evaluation to achieve homogeneity among studies. Standardization of the operative technique, as well as "centralizing" pancreatic resections in high-volume centers, should aid to improve the occurrence of this bothersome postoperative complication.

Introduction: Primary hepatic carcinoid tumours (PHCTs) are extremely rare neuroendocrine neoplasms. Only 58 cases have been reported in the literature and less than 10 cases were functional.
