Sclerosing Mesenteritis Presenting as a Pseudotumor of the Greater Omentum.

Objective: The aim was to demonstrate a diagnostic challenge of sclerosing mesenteritis initially considered as liposarcoma.

Clinical Presentation And Intervention: A 45-year-old man was admitted with a painful abdominal mass. Abdominal computed tomography demonstrated a well- demarcated tumor in his left hemiabdomen, with a large fat component and areas of soft tissue attenuation suggestive of liposarcoma.

Micrometastasis of hypopharyngeal cancer.

Purpose: The aim of this study is to estimate the incidence and clinical impact of lymph node micrometastases in hypopharyngeal squamous cell cancer (HSCC).

Materials And Methods: In this retrospective study, we enrolled 58 patients who have undergone surgery for HSCC (between January 2004 and January 2011). Pharyngolaryngectomy and oesophagectomy with selective bilateral neck dissection was performed in all patients.

Does the computed tomography perfusion imaging improve the diagnostic accuracy in the response evaluation of esophageal carcinoma to the neoadjuvant chemoradiotherapy? Preliminary study.

Purpose: To estimate whether the computed tomography (CT) perfusion imaging could be useful to predict the pathological complete response (pCR) of esophageal cancer to the neoadjuvant chemoradiotherapy (NACRT).

Methods: Twenty-seven patients with the advanced squamous cell esophageal carcinoma, who were treated with concomitant CRT (CIS/5-FU/LV and 45-50 Gy total radiation dose), were re-evaluated using CT examination, which included the low-dose CT perfusion study. CT perfusion series were analysed using the deconvolution-based CT perfusion software (Perfusion 3.

Bloodless esophageal replacement in children with corrosive esophageal strictures--report of two cases.

Background: Esophageal replacement is major procedure with high risk for perioperative allogeneic blood transfusion (ABT), especially in pediatric patients due to nutritive deficiency, anemia, small body weight and blood volume. Autologous blood policy is particularly important in female children.

Methods: We present treatment strategy with the aim of avoiding ABT, that have been applied in two female pediatric patients with caustic stricture of thoracic esophagus.

[Well differentiated endocrine carcinomas of the pancreas].

Introduction: For the difference from poorly differentiated, well differentiated endocrine carcinomas of the pancreas are the tumours in whom with aggressive surgery and chemotherapy fair results can be achieved.

Objective: The aim of the study was to point out the importance of such treatment.

Methods: Over a 6-year period eight patients (seven female and one male) of average age 51 years (ranging from 23 to 71 years) were operated on for well differentiated endocrine carcinoma: six of the head and two of the tail of the pancreas.

Pharyngolaryngoesophagectomy in a patient with an aberrant right subclavian artery: report of a case.

We report a case of carcinoma of the hypopharynx and cervical esophagus in a patient with an aberrant right subclavian artery. Barium esophagography, endoscopy, and computed tomography showed a resectable tumor in the hypopharynx and cervical esophagus, coexistent with an aberrant right subclavian artery. We performed pharyngolaryngoesophagectomy with bilateral neck dissection and gastric pull-up through cervical, right thoracic, and abdominal incisions.

Acinetobacter spp. colonization and infection risk factors in surgical patients.

Introduction: The results of numerous studies carried out over the last two decades have increasingly important cause of intrahospital infections (IHI). The aim of the study was to determine potential differences in distribution of individual risk factors between the group of patients in whom multiresistant Acinetobacter spp. was isolated and the group of patients in whom it was not.

Minimally invasive esophagectomy in the treatment of esophageal cancer.

In the Western countries, the incidence of esophaeal carcinoma is 3-6 cases per 100,000 persons. g Despite tremendous success of other therapeutic options, surgical treatment still represents the best therapeutic option whenever possible. For the long period, debate has centered on which of the a vailable surgical procedures is superior-transhiatal or transthoracic esophagectomy.

[The use of recombinant activated factor VII in the treatment of gastrointestinal bleeding following acetylsalicylic acid therapy in a surgical patient].

Introduction: Gastrointestinal bleeding is the most important complication associated with acetylsalicylic acid therapy. Patients with preexisting haemostatic disorders are at the higher risk and may experience life-threatening hemorrhagic syndrome. Platelet transfusions and desmopressin administration commonly successfully arrest bleeding.

Surgical experience of the national institution in the treatment of Zenker's diverticula.

Aim: To review the 8-year experience of the Department of Esophagogastric Surgery, First Surgical University Hospital in Belgrade in the surgical management of Zenker's diverticula (ZD).

Methods: Between January 2000 and January 2009, 52 patients underwent surgical procedure for the treatment of ZD. Complete preoperative workup including the symptom evaluation and large variety of structural and functional diagnostic procedures were conducted before the surgery.

Colon interposition for pharyngoesophageal postcorrosive strictures.

Background/aim: Aim of this paper is to report a 40 years experience in performing colon interposition for pharyngoesophageal caustic injury.

Methodology: In the period between 1965 and 2005, 83 colon interpositions were performed due to the pharyngeal and high esopahageal injuries. Patients were classified according to the uppermost level of stricture in 3 groups: supraglotic, hypopharyngeal and esophageal ostium.

[Treatment of gastrointestinal hemorrhage manifestation induced by nonsteroidal anti-inflammatory agents]].

Introduction: The risk of upper gastrointestinal tract bleeding in the patients taking NSAID estimates 1% per year. Bleeding stops spontaneously in approximately 80% of all cases. Persistent and repeated bleeding (expecialy during the initial hospitalization) still represent the serious clinical problem.

Primary esophageal diffuse large B-cell lymphoma: report of a case.

Primary esophageal lymphoma is very rare, with fewer than 25 cases documented in the English-language literature. We report a case of primary diffuse large B-cell lymphoma of the esophagus in a 42-year-old woman. Barium esophagogram revealed almost complete esophageal obstruction at the level of the cervical esophagus, and flexible endoscopy showed a circumferential submucosal tumor covered with intact mucosa.

Gastric multicentric glomangioma: a case report of this rare cause of abdominal pain.

Background: A glomus tumor is a rare neoplasm derived from glomus cells, specialized cells that surround small blood vessels which are important in regulating peripheral blood flow. Glomangiomas are a subset of glomus tumors. They are usually localized in the skin and subcutaneous tissue.

[Systemic hemostatic drugs].

Understanding the haemostatic changes is crucial in developing strategies for the management of haemorrhage syndroma. In recent years, the revised model of coagulation ("cell based" model) provided a much more authentic description of the coagulation process. Pharmacological intervention, especially desmopresin, antifibrinolytics (synthetics and nature) and increasingly recombinant activated factor VII are being used in prevention and therapeutically to control bleeding of variety etiologies.

[Upper gastrointestinal bleeding as a surgical complication of primary gastric lymphoma].

Primary gastric lymphomas are of the extranodal non-Hodgkin type. The gastrointestinal tract is the most common site of extranodal non-Hodgkin lymphomas and accounts 30-45% of all extranodal lymphomas. Gastrointestinal lymphomas occurs in the stomach in 55-70% of cases.

[Dieulafoy's lesion: rare cause of massive upper gastrointestinal bleeding].

Dieulafoy's lesion is an unusual and potentially life-threatening cause of massive, recurrent gastrointestinal bleeding. Its reported incidence as a source of upper gastrointestinal bleeding ranges from 0.3-6.

[Less frequent causes of upper gastrointestinal bleeding].

Upper gastrointestinal (GI) bleeding represents emergency which despites modern advances in treatment still carry substantial mortality. Mortality remained relatively constant in the last 50 years at approximately 12%. Peptic ulcers remain the most common cause of upper GI bleeding and account approximately 50% of all cases.

[Gastrointestinal stromal tumors (GIST) of the stomach as a cause of upper gastrointestinal bleeding].

Gastrointestinal stromal tumors (GIST) is the most common mesenchymal tumor of the gastrointestinal tract. GIST is currently defined as a gastrointestinal tract mesenchymal tumor containing spindle cells (less commonly epitheloid cells or rarely both) and showing CD 117 (c-kit protein) positivity in more than 95% of cases. Although they may arise throughout the gut, the commonest site are stomach (60-70%), small intestine (20-30%), colorectum (5%) and esophagus (up to 5%).

[Iron deficiency anemia and its importance in gastroenterology clinical practise].

Iron deficiency anemia (IDA) is a universal problem involving individuals of all ages and both sexes and is a common cause of referral to medical departments. This anemia is one of the most common types of anemia. IDA impairs growth and intellectual development in children and adolescent.
