Pancreatic trauma: The role of computed tomography for guiding therapeutic approach.

Aim: To evaluate the role of computed tomography (CT) for diagnosing traumatic injuries of the pancreas and guiding the therapeutic approach.

Methods: CT exams of 6740 patients admitted to our Emergency Department between May 2005 and January 2013 for abdominal trauma were retrospectively evaluated. Patients were identified through a search of our electronic archive system by using such terms as "pancreatic injury", "pancreatic contusion", "pancreatic laceration", "peri-pancreatic fluid", "pancreatic active bleeding".

Idiopathic adult colo-colonic intussusception: Case report and review of the literature.

Introduction: Acute colonic intussusception occurring in the absence of organic cause is uncommon in adults.

Presentation Of Case: We report acute colonic intussusception in a 46-year-old female; clinical evidence of a palpable mass, abdominal pain and bloody mucoid stools appeared a few hours after hospital admission. Multislice CT-scan confirmed the clinical diagnosis and surgical exploration revealed right colonic obstruction caused by intussusception of the cecum into the ascending colon.

Splenic localization of the peritoneal mesothelioma: case report and literature revue.

Peritoneal mesothelioma is a rare form of malignant mesothelioma, making up <30% of diagnosed mesothelioma cases. Because of a lack of specific symptoms (abdominal pain, abdominal swelling), normally it is diagnosed in advanced stages, sometimes in a surgical emergency (intestinal obstruction, severe ascites) and occasionally during image procedures or laparoscopy which can show a mass developing from peritoneal mesothelium surfaces, or an accumulation of small irregularities that may be tumors or plaques. The reported case refers to a particular localization of a peritoneal mesothelioma, the spleen, discovered only after a splenectomy, due to the clinical and radiological suspect of a rupture.

Case report of a primary multiloculate muscular cystic hydatidosis.

Hydatidosis is a zoonosis caused by the ingestion of Echinococcus granulosus eggs, released though the feces, from infected dogs to humans. Primary localization is mostly hepatic and/or pulmonary, whereas muscular involvement is very rare, even more so in muscular striated tissue. This is the report of a case of a primary intramuscular hydatid cyst in a 79-year-old woman who presented with a 3-year history of a painful lump in her proximal medial left thigh.

Massive gastrointestinal bleeding due to splenotic nodule of the gastric wall. A case report.

Splenosis results from autotransplantation of splenic tissue after traumatic splenic rupture or surgery. Usually asymptomatic, splenosis is an incidental finding at surgery, unrelated to the splenosis, for intestinal obstruction or suspected appendicitis or gynaecological pathology. This article describes a unique case of massive gastrointestinal bleeding caused by deep invasion of a splenotic nodule into the gastric wall.

[Acute appendicitis: is this common pathology still of interest?].

Despite the indisputable progress of technology (laboratory analyses, scintigraphy, ultrasonography, computed tomography), the diagnosis of acute appendicitis often remains uncertain, with a rate of useless appendectomies amounting to almost 20% of cases. The ideal diagnostic test has yet to be discovered and, in any case, clinical observation remains the cornerstone of any decision-making algorithm. Thus, acute appendicitis continues to offer food for thought in relation to the aetiology of the condition, which is still unknown, the primacy of the clinical diagnosis, and the learning of the surgical skills required.

Small bowel obstruction due to intramural hematoma during anticoagulant therapy. With regard to two cases treated conservatively.

Hemorrhage following prolonged oral anticoagulant administrations is a well recognized hazard of therapy, and hemorrhagic complications are said to occur in 10-30% of patients. Following the presentation of the cases, the authors examine the current literature concerning the problems with anticoagulants, and recommend models of diagnosis and treatment of complications by bowel obstruction. Authors report on two cases of small bowel obstruction due to intramural hematoma during anticoagulant therapy.

Pathobiology of cholesterol gallstone disease: from equilibrium ternary phase diagram to agents preventing cholesterol crystallization and stone formation.

The primum movens in cholesterol gallstone formation is hypersecretion of hepatic cholesterol, chronic surpersaturation of bile with cholesterol and rapid precipitation of cholesterol crystals in the gallbladder from cholesterol-enriched vesicles. Associated events include biochemical defects (increased biliary mucin, and increased proportions of hydrophobic bile salts in the intestine and gallbladder), motility defects (gallbladder smooth muscle hypocontractility in vitro and gallbladder stasis in vivo, sluggish intestinal transit), and an abnormal genetic background. The study of physical-chemical factors and pathways leading to cholesterol crystallization in bile has clinical relevance and the task can be carried out in different ways.
