Management of malignant struma ovarii: is aggressive therapy justified? Case report and literature review.

Background: Struma ovarii (SO) is a rare ovarian teratoma containing predominantly thyroid tissue. In rare situations SO may develop malignancy. Most cases of malignant struma ovarii (MSO) are diagnosed after surgical removal, based on histopathological examination.

Gastrointestinal Stromal Tumors - Diagnosis and Surgical Treatment.

Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumors of the gastrointestinal tract, previously classified as leiomyomas, leiomyosarcomas, leiomyoblastomas or schwannomas. They are now recognized as a distinct entity with origin in the mesodermal interstitial cell of Cajal, cells that express the c-KIT protein (tirozine kinase receptor). The definitive diagnosis is established by immunohistochemistry, more than 95% of GISTs being positive for CD117.

The surgical treatment for Crohn's disease.

Introduction: Crohn's disease is a chronic idiopathic medical and surgical disease, in which the transmural intestinal inflammatory process frequently leads to complications such as strictures or fistulae. The disease is considered to be the result of an imbalance between the proinflammatory mediators and the anti-inflammatory ones; it can be localized on any segment of the gastrointestinal tract, but it especially affects the terminal ileum. The purpose of the study is to assess Crohn's disease from the point of view of the complications requiring surgical treatment, the manner in which they are solved, as well as the postoperative evolution.

[Unique duodenal hamartomatous polyp--case report].

Duodenal tumors are very rare tumors, with the lower incidence among the tumors of the small bowel, whose frequence is less than 5 % of all digestive tumors. In most of the cases these tumors remain asymptomatic, sometimes the entire life. When they become symptomatic, their first manifestation is the loss of digested blood (melena), secondary anemia and obstructive symptomatology.

[Gastrointestinal stromal tumor with primary hepatic unique location--clinical case].

The gastrointestinal stromal tumors are mesenchymal tumors whose primary extradigestive location is very rare (less than 10% primary liver localization). We present a clinical case of primary hepatic location of GIST in a 28 year-old patient. The discovery of this tumor is a chance, the patient presenting for non-specific dyspeptic syndrome and epigastralgia.

Colorectal cancer and the 7th revision of the TNM staging system: review of changes and suggestions for uniform pathologic reporting.

Colorectal cancer (CRC) is a neoplastic disease with a continuously growing incidence in Romania and throughout the world. Although the surgery remains the first line treatment for most of the cases, newly discovered targeted molecular therapies - effective for some patients, but with various side effects and significant financial burden for the national health systems - requires not only stratification of patients in prognostic groups but also evaluation of some non-anatomic factors with major impact on the prognosis and therapeutic strategy. The AJCC/UICC TNM staging system, in his 7th revision, effective for cases diagnosed on or after January 1, 2010, responds to these needs.

[Consideration regarding 20 antireflux laparoscopic operations for hiatal hernia].

Aim: To evaluate the clinical, therapeutical and evolutive aspects of the patients with hiatal hernia with laparoscopical approach.

Materials And Methods: Retrospective analysis of 20 patients diagnosed with hiatal hernia and operated, laparoscopical, between 13.01.

[Dedifferentiated liposarcoma of the omentum].

The authors present the case of a 56 years old patient, from the surgery department, with the diagnostic: "Tumoral abdominal mass". Ultrasound investigation and CT-scan suspicioned a malignant omental tumor. Intraoperator, we found a tumor with macroscopic malignant features (sarcomatous like), greow in omentum; the large border of the stomach being fixed but not invaded by it; the dorsal parietal peritoneum of the right lumba and the little omentum were involved, too.

[Gastric stromal tumor treated by laparoscopic surgery].

Unlabelled: The authors describe a 59 years old female patient, with a gastrointestinal stromal tumor located on the posterior wall of the gastric funds, who was treated successfully by laparoscopic wedge resection (with clear resection margins), through an anteriorly placed gastrotomy, thus allowing an endoscopic linear cutter Endo GIA, to excise the tumor with a cuff of normal gastric tissue. The anterior gastrotomy was performed with Ultra-Shears. Delivery of the tumor through the gastrotomy is essential for success.

[Cortico-suprarenal carcinoma].

The authors show the case of a 69 years old male with a large corticosuprarenalian tumor that was detected on an random abdominal echographic examination. The patient was operated in the General Surgery Department. of Prof.
