Objective: To demonstrate a diagnostic challenge of sclerosing mesenteritis initially considered as liposarcoma.
Clinical Presentation and Intervention
Clinical Presentation and Intervention: A 45-years old man was admitted with a painful abdominal mass. Abdominal computed tomography demonstrated a well-demarcated tumor in left hemiabdomen, with a large fat component and areas of soft tissue attenuation suggestive for liposarcoma. Intraoperative finding showed a tumor arising from the greater omentum. The tumor was removed and histopathology confirmed pseudotumorous type of sclerosing mesenteritis with dominant mesenteric lipodystrophy.
Conclusion:The pseudotumorous type of sclerosing mesenteritis should be considered in differential diagnosis of the mesenteric tumors .

The Saint’s triad was recognized when association between hiatal hernia, colonic diverticular disease, and gallstones have been proven to appear more often than just by pure chance alone. Methodology A systematic review of the literature was performed using MEDLINE (PubMed search), EMBASE, and the Cochrane databases, and it included papers published from 1948 until 2014. Results The data obtained by search are presented to analyze the theory of herniosis. Connective tissue disorder is being recognized as a cornerstone beneath the Saint’s triad, and the facts backing up this stand point are now systematically displayed to readers. Special emphasis is given on review of current literature reports on origin of hiatal hernia and its influence on everyday surgical perceptive. Conclusion Saint’s triad, once the most cited example of Hickam’s dictum is now being put to trial with the theory of herniosis, proving a sharper edge to Ockham razor stand point. It is upon the reader, from the arguments given, to choose which principle will prevail, in further thinking about this particular problem.
[Show abstract][Hide abstract] ABSTRACT: The aim of this study is to estimate the incidence and clinical impact of lymph node micrometastases in hypopharyngeal squamous cell cancer (HSCC).
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. Based on standard histological examination, 17 patients met N0 and 8 patients met N1 criteria and were further evaluated for the presence of micrometastases and isolated tumour cells (ITC). Following immunohistochemical analysis, the patients were grouped according to the presence of micrometastases and ITCs.
In the pN0 group, cytokeratin-positive cells were detected in five patients, and they were marked as N0/CK+. Among these five patients, two were found to harbour micrometastases and ITCs, whilst in three, only ITCs were found. Two patients (11.75 %) were upstaged to pN1. The patients marked as N0/CK+ had a statistically significant worse overall survival rates than pN0 patients with tissue samples read as negative for cytokeratin immunostaining (p = 0.019, p < 0.05). In the pN1 group, cytokeratin-positive cells were detected in two patients, with one patient showing micrometastases and ITC, and the other showing ITC only. One patient was upstaged to pN2.
Patients with lymph node micrometastases and ITC had worse overall survival rates, which may indicate that more aggressive post-operative treatment regimens should be considered for these HSCC patients.

[Show abstract][Hide abstract] ABSTRACT: 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).
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 3.0, GE), and color parametric maps of the blood flow (BF), blood volume (BV), mean transit time (MTT), and permeability surface area product (PS) were displayed. All patients were operated and histopathological analysis of the resected esophagus considered the gold standard for pathologic complete response (pCR).
BFpost-NACRT, BVpost-NACRT, and PSpost-NACRT were significantly lower, and MTTpost-NACRT significantly higher in the pCR group. Mean (±SD), or median perfusion parameter values in the pCRs (11 patients) vs non-pCRs (16 patients) were: BFpost-NACRT- 21.4±5.0 vs 86.0±29 ml/min/100 g (p<0.001), BVpost-NACRT- 1.3 vs 3.9 ml/100 g (p<0.001), MTTpost-NACRT- 5.5 vs 3.7 s (p=0.018), and PSpost-NACRT- 5.9 vs 9.8 ml/min/100 g (p=0.006). ROC analysis revealed that BFpost- NACRT (AUC=1.000), BVpost-NACRT (AUC=0.932), MTTpost-NACRT (AUC=0.801), and PSpost-NACRT (AUC=0.844) could predict the pCR (p<0.01), while maximal esophageal wall thickness could not (AUC=0.676, p=0.126). If we set a cut-off value of BFpost-NACRT<30.0 ml/min/100 g, pCR was predicted with sensitivity and specificity of 100%.
CT perfusion imaging enables accurate prediction of pCR of esophageal carcinoma to neoadjuvant chemoradiotherapy.

[Show abstract][Hide abstract] ABSTRACT: 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.
The aim of the study was to point out the importance of such treatment.
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. There were two functional and six nonfunctional tumours. Pain in the upper part of the abdomen in seven, mild loss in weight in two, strong heartburn in two, obstructive jaundice in three, diarrhoea in one, sudden massive bleeding from gastric varicosities due to prehepatic portal hypertension caused by pancreatic head tumour in one, and bruise in one patient were registered preoperatively. US and CT in all, angiography in one, octreoscan in two and PET scan in one patient were performed. Whipple's procedure was performed in six and distal pancreatectomy in two patients, as well as systemic lymphadenectomy in all and excision of liver secondary tumours in two patients. In the patient with massive gastric bleeding a total gastrectomy was performed first, followed by Whipple's procedure a month later.
R0 resection was achieved in all patients. Lymph nodes metastases were found in six patients. Six patients were given chemotherapy. One patient died 3 years after surgery, seven are still alive, on average 2.5 years. A local recurrence after distal pancreatectomy that occurred 5 years after surgery was successfully reresected and the patient is on peptide-receptor radiotherapy. In other six patients there were no local recurence or distant metastases.
With aggressive surgery and chemotherapy fair results can be achieved in well differentiated endocrine carcinomas of the pancreas.

[Show abstract][Hide abstract] ABSTRACT: 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. We also partially resected the aberrant right subclavian artery with reimplantation in the right common carotid artery. To our knowledge, this is the first report of pharyngolaryngoesophagectomy with transposition of an aberrant right subclavian artery.
[Show abstract][Hide abstract] ABSTRACT: 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.
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. The patients were 7 and 8 years old, with body weight 34 and 23.5 kg, respectively. Protocol was based on the stimulation of haematopoetic system with erythropoietin, iron therapy and preoperative autologous blood donation (PABD). In the first patient, with a history of previous retrosternal bypass esophagocoloplasty and extraction of necrotic colonic graft, delayed reconstruction--transhiatal subtotal esophagectomy and gastric pull-up with cervical anastomosis were performed. In the second patient, repeated ineffective dilatations of esophageal stricture were reason for retrosternal left colon interposiotion and exclusion of native esophagus.
No adverse events were attributed to preoperative blood donation period. No allogenic blood products were used during perioperative period. Both patients had uneventful postoperative course.
In specialized institutions for esophageal surgery, PABD with administration of erythropoietin and iron therapy, enable bloodless esophageal replacement, even in children.

[Show abstract][Hide abstract] ABSTRACT: 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. Minimally invasive esophagectomy (MIE) could offer both minimally invasive approach and proper mediastinal lymph node dissection. Minimally invasive esophagectomy is safe and adequate, but time consuming and technically demanding procedure. It is procedure reserved for the surgeons experienced in open esophagectomy for cancer, and specially trained in advanced minimally invasive procedures. Even in that case, learning curve is steep.

[Show abstract][Hide abstract] ABSTRACT: 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.
A prospective cohort study of 64 patients hospitalized with recorded IHI at the University Hospital for Digestive Surgery, Clinical Center of Serbia in the period between January and July 2011. The subjects were divided into two groups: patients with IHI in whom multiresistant Acinetobacter spp. was isolated from the biological material samples, and those with IHI without the presence of Acinetobacter spp.
Univariate data analysis indicated presence of statistically significant difference in distribution of certain types of surgeries (esophageal, pancreatic and hepatobiliary) among the two groups of subjects, distribution of CVC placement, application of mechanical ventilation and nasogastric tube placement, length of stay in ICU, lethal outcomes and administration of third generation cephalosporins. The results of multivariate analysis indicated that length of hospitalization in ICU (> 7 days), CVC, mechanical ventilation, esophageal, pancreatic and hepatobiliary surgeries as well as administration of third generation cephalosporins are independent risk factors for colonization and infection of patients with Acinetobacter spp.
Colonized or infected patients with Acinetobacter spp. play a major role in contamination of hands of the medical staff in the course of care and treatment, while inadequate hand hygiene of the staff leads to cross transmission of the causative organism to infection-free patients. Selective antibiotic pressure, particularly administration of quinolones and broad-spectrum cephalosporins, favor onset of multiresistant species of Acinetobacter spp., and therefore appropriate prophylaxis and treatment represent basic preventive measures against the onset and spreading of the causative organisms.

[Show abstract][Hide abstract] ABSTRACT: 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).
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. After the operative treatment patients underwent detailed follow-up in regular intervals up to 3 years.
Preoperative evaluation marked higher incidence of hiatal hernia and pathologic gastroesophageal reflux (GER) among the patients with ZD then in normal population. According to the preoperative evaluation and size of diverticula, as well as due to the intraopertive findings, a variety of surgical procedures were performed, including myotomy alone (n = 2), diverticulopexy and myotomy (n = 36) and diverticulectomy and myotomy (n = 14). Regardless of the operative treatment no salivary cervical fistulas were observed. Late and early postoperative results revealed low incidence in postoperative transitory dysphagia or regurgitation. Conclusion: The results of this study show that the open surgical procedures are safe and effective in the treatment of ZD. Cricopharyngeal myotomy remains the essential focus of treatment, while the choice of resecting or suspending the diverticulum is brought upon its size. Complete preoperative investigation must be conducted in ZD patients, and the role of pathologic GER must be taken into account when we discuss the origin of this disorder.

[Show abstract][Hide abstract] ABSTRACT: Aim of this paper is to report a 40 years experience in performing colon interposition for pharyngoesophageal caustic injury.
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. In most of the patients (89.1%) an extrapleural retrosternal by-pass colon interposition was performed, while in the remaining 10.9% a colon interposition with esophagectomy had to be done. Long-term follow-up results were obtained in the period between one and up to 30 years.
Early postoperative complications occurred in 16.8% of patients, among which anastomotic leakage was the most common. Overall intrahospital mortality rate was 6%, while late postoperative complications were present in 14.4% of patients. Long-term follow-up was obtained in 84.2% of patients, with excellent functional results being present in 86.7% of them.
Colon graft is an excellent esophageal substitute for patients with pharyngoesophageal corrosive strictures, and used by experienced surgical team it provides low postoperative morbidity as well as mortality rate, and a long time good and functional quality of life.

[Show abstract][Hide abstract] ABSTRACT: 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. However, in clinical situations with profound bleeding and haemorrhagic shock, these therapeutic approaches may fail. CASE OUTLINE We report a 24-year old female patient with previously undetected acquired platelet dysfunction, who underwent reconstructive surgical intervention. On the 20(th) postoperative day, acetylsalicylic acid was introduced due to reactive thrombocytosis (platelet count 1480x10(9)/L) with daily dose of 100 mg tablets. On the 12(th) day of the acetylsalicylic acid treatment, massive gastrointestinal bleeding with haemorrhagic shock suddenly occurred. Attempts to control massive haemorrhage by resuscitation, blood products and haemostatics (desmopressin, tranexamic acid) failed. Two bolus doses of recombinant activated factor VII (rFVIIa) (100 mu g/kg and 60 mu g/kg respectively) in 90 minutes interval were given. Bleeding was successfully controlled with no requirements for further haemoproducts and haemostatic remedies treatment. CONCLUSION This case demonstrates that the use of rFVIIa may be a specific treatment option in patients suffering from severe gastrointestinal bleeding associated with acetylsalicylic acid treatment.

[Show abstract][Hide abstract] ABSTRACT: 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. They have also been reported in viscera, most notably in the gastrointestinal tract.
A case of gastric multicentric glomangioma is described in an 18-year-old male who presented with chronic continuous abdominal pain over a 4-6 month period. Preoperative diagnosis, operative findings, histology, and immunohistochemistry of the tumor are discussed in detail.
Case reports of this rare tumor are important because of the paucity of studies noted in the gastro-intestinal literature as a result of poor identification prior to the advent of modern immunohistochemistry. The significance of accurately diagnosing a gastrointestinal glomangioma is crucial for appropriate treatment.

[Show abstract][Hide abstract] ABSTRACT: 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. Neck magnetic resonance imaging (MRI) showed a wide cervical mass circumferentially encompassing the lumen of the cervical esophagus. Biopsies taken with multiple forceps during flexible and rigid esophagoscopy were nondiagnostic. Finally, external esophageal wall biopsies taken during neck exploration provided information that helped us establish the diagnosis. Pathohistological findings confirmed non-Hodgkin's lymphoma of the diffuse large B-cell type. The patient was treated with combined immunochemotherapy, consisting of rituximab plus cyclophosphamide, vincristine, adriablastin, and prednisone (CHOP), followed by irradiation. A complete response was achieved, and 3 years after diagnosis and treatment the patient was disease-free.
[Show abstract][Hide abstract] ABSTRACT: 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. In this group of patients, mortality rate is between 6-10%, which in the USA counts 10-20000 patients per year.
The purpose of this review is to update the current knowledge of the use of different therapeutic strategies in patients with NSAID induced upper gastrointestinal bleeding.
Proton pump inhibitors (PPI) therapy is effective as a prevention of NSAID induced acidopeptic lesions, and also represents the first and best therapeutic option for the treatment of complications, such as upper gastrointestinal bleeding. In the last three decades use of early flexibile (diagnostic and therapeutic) endoscopy, agressive acidosupression (PPIs), and surgical treatment in restrictive indications, resulted in decreasing of the mortality rates from 25-35% to 6-10%. When PPIs and flexible endoscopy are not sufficient in the control of upper gastrointestinal bleeding, use of systemic hemostatic drugs could be taken into consideration.
Multidisciplinary approach, precise diagnostic and therapeutic critearia would probably result in better outcome of patients with active upper gastrointestinal bleeding.

[Show abstract][Hide abstract] ABSTRACT: 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 0.3-6.7%. Dieulafoy's lesion is most commonly located in the proximal stomach (75% of cases). Lesion typically occur within 6 to 10 cm of the esophagogastric junction, generally along the lesser curvature of the stomach. Similar lesions have been identified in the esophagus, duodenal bulb, jejunum, ileum, colorectum, anal canal, even in bronchus. Detection and identification of the Dieulafoy's lesion as the source of bleeding can often be difficult, especially because most present with massive bleeding. Because of intermittent nature of bleeding, initial endoscopy is diagnostic in 60% of the cases, so repeated endoscopies are often necessary. If the lesion can be endoscopically documented, attempts should be made to achieve hemostasis using one or a combination of several endoscopic modalities. Success has been reported with multipolar electrocoagulation, heater probe, noncontact laser photocoagulation, injection sclerotherapy, endoscopic hemoclipping and band ligation. Surgery is reserved for lesions that cannot be controlled by endoscopic techniques. When localized, a wide wedge resection of entire area traversed by the large submucosal artery is recomended because rebleeding has been described after simple coagulation and ligation.

[Show abstract][Hide abstract] ABSTRACT: 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. In women IDA is most common in reproductive period because of menstrual and pregnancy iron losses. IDA affects roughly 10-30% of all pregnancies and, among others morbidities, may contribute of developing postpartum depression. Among other adult patient, chronic occult gastrointestinal bleeding is the leading cause of IDA. Approximately, one third of patients with anemia have iron deficiency and up to two thirds of patients with IDA have serious gastrointestinal lesions detected with esophagogastroduodenoscopy and colonoscopy, including 10-15% with malignancy. However, in practice not all anemic patients undergo appropriate diagnostic tests to detect iron deficiency. Furthermore, a substantial proportion of patients with IDA do not undergo endoscopic evaluation. The approach to its investigation and subsequent therapy depends upon a comprehensive understanding of iron metabolism and heme synthesis. Once diagnosis of iron deficiency or IDA is established, evaluation for the cause of anemia must be appropriate performed and treatment must include corrective replenishment of body stores.
