| 1 | EUS mini probes in diagnosis of cystic dystrophy of duodenal wall in heterotopic pancreas:A case report显示文摘Cystic dystrophy of the duodenal wall is a rare condition characterized by the development of cysts in heterotopic pancreatic tissue localized in the duodenal wall. A 38-year-old man was admitted to the hospital for abdominal pain and vomiting after food intake. The diagnosis of acute pancreatitis was initially suspected. Abdominal ultrasound examination revealed thickening of the second portion of duodenal wall within which, small cysts (diameter, less than 1 cm) were present in the vicinity of pancreatic head.The head of pancreas appeared enlarged (63 mm×42 mm)and hypoechoic. Upper endoscopy and barium X-ray series were performed revealing a severe circumferential deformation, as well as 4 cm long stenosis of the second portion of the duodenum. CT examination revealed multiple cysts located in an enlarged, thickened duodenal wall with moderate to strong post-contrast enhancement. We suspected that patient had cystic dystrophy of duodenal wall developed in the heterotopic pancreas and diagnosis was confirmed by endoscopic ultrasound (EUS). Endoscopi cutrasound (EUS) revealed drcular stenosis from the duodenal bulb onwards. A twenty megaHertz mini-probe examination further showed diffuse (intramural) infiltration of duodenal wall limited to the submucosa and muscularis propria of the second portion of duodenum with multiple microcysts within the thickened mucosa and submucosa, a. Patient was successfully surgically treated and pancreatoduodenectomy was performed. The pathological examination confirmed a diagnosis of cystic dystrophy of a heterotopic pancreas.Endoscopic ultrasonography features allow preoperative diagnosis of cystic dystrophy of a heterotopic pancreas in duodenal wall, with inb'alumina120 MHz mini probe sonography being more efficient in cases of luminal stenosis. | Ivan Jovanovic Srbislav Knezevic Miodrag Krstic Marjan Micev | 2004 | World Journal of Gastroenterology2004，10，17： | 8 |
| 2 | Cystic lymphangioma of the pancreas显示文摘Lymphangioma of the pancreas is an extremely rare benign tumour of lymphatic origin,with fewer than 60 published cases. Histologically,it is polycystic,with the cysts separated by thin septa and lined with endothelial cells. Though congenital,it can affect all age groups,and occurs more frequently in females. Patients usually present with epigastric pain and an associated palpable mass. Complete excision is curative,even though,depending on the tumour location,surgery may be simple or involve extensive pancreatic resection and anastomoses. The authors present a 49-year-old woman in whom a polycystic septated mass,35 mm x 35 mm in size,was discovered by ultrasonography (US) in the body of the pancreas during investigations for epigastric pain and nausea. At surgery,a well circumscribed polycystic tumor was completely excised,with preservation of the pancreatic duct. The postoperative recovery was uneventful. Histology confirmed a microcystic lymphangioma of the pancreas. Immunohistochemistry showed cystic endothelial cells reactivity to factor Ⅷ -RA (++),CD31 (+++) and CD34 (-). Postoperatively,abdominal pain disappeared and the patient remained symptomfree for 12 mo until now. Although extremely rare,lymphangioma of the pancreas should be taken into consideration as a differential diagnosis of a pancreatic cystic lesion,especially in women. | Radoje B Colovic Nikica M Grubor Marjan T Micev Henry Dushan E Atkinson Vitomir I Rankovic Mihajlo M Jagodic | 2008 | World Journal of Gastroenterology2008，14，44： | 6 |
| 3 | Primary retroperitoneal mucinous cystadenoma:A case report显示文摘Primary retroperitoneal mucinous cystic tumors are extremely rare.These tumors can be classified as a primary retroperitoneal mucinous cystadenoma with or without borderline malignancy or primary retroperitoneal mucinous cystadenocarcinoma.The most common of these is primary retroperitoneal mucinous cystadenoma,which almost always occurs in female patients;only ten cases have been reported in males.The most common clinical findings for this tumor type include nonspecific abdominal pain and a palpable abdominal mass.A definitive diagnosis is usually obtained from histopathology after surgical excision.Here,we report the case of a 60-year-old female patient who complained of abdominal pain that had been present for 3 mo and presented with a palpable abdominal mass.Multidetector computed tomography scanning revealed a large,unilocular cystic mass in the left retroperitoneal space.Surgical intervention was performed and the tumor was completely removed.Histopathologic examination confirmed that the tumor was a primary retroperitoneal mucinous cystadenoma.Two years after surgery,the patient remains disease free. | Srbislav Knezevic Igor Ignjatovic Snezana Lukic Slavko Matic Vladimir Dugalic Djordje Knezevic Marjan Micev Sanja Dragasevic | 2015 | World Journal of Gastroenterology2015，21，17： | 3 |
| 4 | Perigastric extraskeletal Ewing's sarcoma: A case report显示文摘Ewing's sarcoma (ES) is a neoplasm of undifferentiated small round cells, which occurs in the bones and deep soft tissues of children and adolescents. We present a rare case of a 44-year-old woman with gastric ES presenting with epigastric pain and weight loss. Ultrasound and computed tomography scans indicated a solid/cystic mass in the pancreatic tail. At laparotomy, the tumor was found attached to the posterior surface of the stomach, completely free from the pancreas, with no lymphadenopathy or local metastases. The polynodal, partly pseudocystic, dark-red soft tumor was excised. Histopathology revealed an anaplastic small-round-cell tumor with strong membranous CD99 immunoexpression. Additionally, there was patchy immunostaining for S-100 protein, vimentin, protein gene product (PGP) 9.5 and neuron-specifi c enolase, and weak focal CD117 cytoplasmic immunoreactivity. The patient had no adjuvant chemotherapy; her postoperative recovery was uneventful, and she remains symptom-free, and without any sign of recurrence at 20 mo. To the best of our knowledge, this is only the third ever case of gastric ES. | Radoje B Colovic Nikica M Grubor Marjan T Micev Slavko V Matic Henry Dushan Edward Atkinson Stojan M Latincic | 2009 | World Journal of Gastroenterology2009，15，2： | 2 |

| 6 | Two synchronous somatostatinomas of the duodenum and pancreatic head in one patient显示文摘Somatostatinomas are extremely rare neuroendocrine tumors of the gastrointestinal tract,f irst described in the pancreas in 1977 and in the duodenum in 1979.They may be functional and cause somatostatinoma or inhibi-tory syndrome,but more frequently are non-functioning pancreatic endocrine tumors that produce somatostatin alone.They are usually single,malignant,large lesions,frequently associated with metastases,and generally with poor prognosis.We present the unique case of a 57-year-old woman with two synchronous non-function-ing somatostatinomas,one solid duodenal lesion and one cystic lesion within the head of the pancreas,that were successfully resected with a pylorus-preserving Whipple's procedure.No secondaries were found in the liver,or in any of the removed regional lymph nodes.The patient had an uneventful recovery,and remains well and symptom-free at 18 mo postoperatively.This is an extremely rare case of a patient with two synchro-nous somatostatinomas of the duodenum and the pancreas.The condition is discussed with reference to the literature. | Radoje B olovi Slavko V Mati Marjan T Micev Nikica M Grubor Henry Dushan Atkinson Stojan M Latini | 2009 | World Journal of Gastroenterology2009，15，46： | 1 |
| 7 | Abdominal neurenteric cyst显示文摘Neurenteric cysts are extremely rare congenital anomalies,often presenting in the first 5 years of life,and are caused by an incomplete separation of the notochord from the foregut during the third week of embryogenesis. They are frequently accompanied with spinal or gastrointestinal abnormalities,but the latter may be absent in adults. Although usually located in the thorax,neurenteric cysts may be found along the entire spine. We present a 24-year-old woman admitted for epigastric pain,nausea,vomiting,low grade fever and leucocytosis. She underwent cystgastrostomy for a loculated cyst of the distal pancreas at the age of 4 years,which recurred when she was at the age of 11 years. Ultrasound and computer tomograghy(CT) scan revealed a 16 cm × 15 cm cystic mass in the body and tail of pancreas,with a 6-7 mm thickened wall. Laboratory data and chest X-ray were normal and spinal radiographs did not show any structural abnormalities. The patient underwent a complete cyst excision,and after an uneventful recovery,remained symptom-free without recurrence during the 5-year follow-up. The cyst was found to contain 1200 mL of pale viscous fluid. It was covered by a primitive single-layered cuboidal epithelium,along with specialized antral glandular parenchyma and hypoplastic primitive gastric mucosa. Focal glandular groups resemblingthose of the body of the stomach were also seen. In addition,ciliary respiratory epithelium,foci of squamous metaplasia and mucinous glands were present. The wall of the cyst contained a muscular layer,neuroglial tissue with plexogenic nerve fascicles,Paccini corpuscle-like structures,hyperplastic neuroganglionar elements and occasional psammomatous bodies,as well as fibroblast-like areas of surrounding stroma. Cartilagenous tissue was not found in any part of the cyst. Immunohistochemistry confirmed the presence of neurogenic elements marked by S-100,GFAP,NF and NSE. The gastric epithelium showed mostly CK7 and EMA immunoexpression,and the respiratory epithelium revealed a CK8 and CK18 immunoprofile without CK 10/13 positive elements,though neither CEA or AFP positive cells were found. To our knowledge,this is the first reported case of an abdominally located neurenteric cyst with no associated spinal anomalies. | Radoje olovi Marjan Micev Miodrag Jovanovi Slavko Mati Nikica Grubor Henry Dushan E Atkinson | 2008 | World Journal of Gastroenterology2008，14，23： | 1 |

| 9 | Gastrin and antral G cells in course of Helicobacter pylori eradication: Six months follow up study显示文摘AIM: To assess long-term effects of Helicobacter pylori (H pylori) eradication on antral G cell morphology and function in patients with and without duodenal ulcer (DU).METHODS: Consecutive dyspeptic patients referred to the endoscopy entered the study. Out of 39 H pylori positive patients, 8 had DU (H pylori+DU) and 31 gastritis (H pylori +G). Control groups consisted of 11 uninfected dyspeptic patients (CG1) and 7 healthy volunteers (CG2). Basal plasma gastrin (PGL), antral tissue gastrin concentrations (ATGC), immunohistochemical and electron microscopic characteristics of G cells were determined, prior to and 6 mo after therapy.RESULTS: We demonstrated elevated PGL in infected patients compared to uninfected controls prior to therapy.Elevated PGL were registered in all H pylori+patients (H pylori +DU: 106.78±22.72 pg/mL, H pylori+G: 74.95±15.63,CG1: 68.59±17.97, CG2:39.24±5.59 pg/mL, P<0.01).Successful eradication (e) therapy in H pylori+patients lead to significant decrease in PGL (H pylori+DU: 59.93±9.40and H pylori+Ge: 42.36±10.28 pg/mL, P<0.001). ATGC at the beginning of the study were similar in infected and uninfected patients and eradication therapy lead to significant decrease in ATGC in H pylori+gastritis, but not in DU patients. In the H pylori+DU patients, the mean number of antral G cells was significantly lower in comparison with all other groups (P<0.01), but after successful eradication was close to normal values found in controls. By contrast, G cell number and volume density were significantly decreased (P<0.01) in H pylori+Ge group after successful eradication therapy (294±32 and 0.31±0.02,respectively), in comparison to values before eradication (416±40 and 0.48±0.09). No significant change of the G cell/total endocrine cell ratio was observed during the 6 mo of follow up in any of the groups. A reversible increase in G cell secretory function was seen in all infected individuals, demonstrated by a more prominent secretory apparatus. However, differences between DU and gastritis group were identified.CONCLUSION: H pylori infection induces antral G cell hyperfunction resulting in increased gastrin synthesis and secretion. After eradication therapy complete morphological and functional recovery is observed in patients with gastritis. In the DU patients some other factors unrelated to the H pylori infection influence antral G cell morphology and function. | Aleksandra Sokic-Milutinovic Vera Todorovic Tomica Milosavljevic Marjan Micev Neda Drndarevic Olivera Mitrovic | 2005 | World Journal of Gastroenterology2005，11，27： | 1 |
| 10 | Metastatic melanoma to the common bile duct causing obstructive jaundice:A case report显示文摘Metastatic melanoma to the common bile duct is very rare with only 18 cases reported so far. We report a 46 year old women who, 18 mo after excision of a skin melanoma, developped a painless progressive obstructive jaundice. At operation a melanoma within the distal third of the common bile duct was found. There were no other secondaries within the abdomen. The common bile duct, including the tumor, was resected and anastomosed with Roux-en-Y jejunal limb. The patient survived 31 mo without any sign of local recurrence and was submitted to three other operations for axillar and brain secondaries, from which she finally died. Radical resection of metastatic melanoma to the common bile duct may result in lifelong relief of obstructive jaundice. It is safe and relatively easy to perform. In other cases, a less aggressive approach, stenting or bypass procedures, should be adopted. | Radoje B Colovic Nikica M Grubor Miodrag D Jovanovic Marjan T Micev Natasa R Colovic | 2007 | World Journal of Gastroenterology2007，13，5： | 1 |
| 11 | Perineural invasion as a prognostic factor in patients with stage Ⅰ-Ⅲ rectal cancer –5-year follow up显示文摘BACKGROUND Rectal cancer(RC)is one of the most common diagnosed cancers,and one of the major causes of cancer-related death nowadays.Majority of the current guidelines rely on TNM classification regarding therapy regiments,however recent studies suggest that additional histopathological findings could affect the disease course.AIM To determine whether perineural invasion alone or in combination with lymphovascular invasion have an effect on 5-years overall survival(OS)of RC patients.METHODS A prospective study included newly diagnosed stage I-III RC patients treated and followed at the Digestive Surgery Clinic,Clinical Center of Serbia,between the years of 2014–2016.All patients had their diagnosis histologically confirmed in accordance with both TMN and Dukes classification.In addition,the patient’s demographics,surgical details,postoperative pathological details,differentiation degree and their correlation with OS was investigated.RESULTS Of 245 included patients with stage Ⅰ-Ⅲ RC,lymphovascular invasion(LVI)was identified in 92 patients(38%),whereas perineural invasion(PNI)was present in 46 patients(19%).Using Kaplan-Meier analysis for overall survival rate,we have found that both LVI and PNI were associated with lower survival rates(P<0.01).Moreover when Cox multiple regression model was used,LVI,PNI,older age,male gender were predictors of poor prognosis(HR=5.49;95%CI:2.889-10.429;P<0.05).CONCLUSION LVI and PNI were significant factors predicting worse prognosis in early and intermediate RC patients,hence more aggressive therapy should be reserved for these patients after curative resection. | Milica Stojkovic Lalosevic Tamara Milovanovic Marjan Micev Mirjana Stojkovic Sanja Dragasevic Milos Stulic Ivan Rankovic Vladimir Dugalic Zoran Krivokapic Aleksandra Pavlovic Markovic | 2020 | World Journal of Gastrointestinal Oncology2020，12，5： | 1 |
| 12 | Tuberculous lymphadenitis as a cause of obstructive jaundice:A case report and literature review显示文摘Obstructive jaundice secondary to tuberculosis (TB) is extremely rare. It can be caused by TB enlargement of the head of the pancreas, TB lymphadenitis, TB stricture of the biliary tree, or a TB mass of the retroperitoneum. A 29-year-old man with no previous history of TB presented with abdominal pain, obstructive jaundice, malaise and weight loss. Ultrasonography (US), computer tomography (CT) scan and endoscopic retrograde cholangiopancreatography (ERCP) were suggestive of a stenosis of the distal common bile duct (CBD) caused by a mass in the posterior head of the pancreas. Tumor markers, CEA and CA19-9 were within normal limits. At operation, an enlarged, centrally caseous lymph node of the posterior head of the pancreas was found, causing inflammatory stenosis and a fistula with the distal CBD. The lymph node was removed and the bile duct resected and anastomosed with the Roux-en Y jejunal limb. Histology and PCR based-assay confirmed tuberculous lymphadenitis. After an uneventful postoperative recovery, the patient was treated with anti-tuberculous medication and remained well 2.5 years later. Though obstructive jaundice secondary to tuberculous lymphadenitis is rare, abdominal TB should be considered as a differential diagnosis in immunocompromised patients and in TB endemic areas. Any stenosis or fistulation into the CBD should also be taken into consideration, and biliary bypass surgery be performed to both relieve jaundice and prevent further stricture. | Radoje Colovic Nikica Grubor Rada Jesic Marjan Micev Tanja Jovanovic Natasa Colovic Henry Dushan Atkinson | 2008 | World Journal of Gastroenterology2008，14，19： | 1 |
| 13 | Gallbladder villous adenoma in a patient with acromegaly:A case report显示文摘Villous adenomas are benign epithelial lesions with malignant potential that can occur in any part of the gastrointestinal tract. We present a case of a middle age woman with acromegaly who was investigated for nonspecifi c gastrointestinal complaints. Ultrasonography and subsequent endosonography diagnosed a large (4.5 cm), hyperechoic, sessile polyp with numerous pedicles. An open cholecystectomy was performed and revealed a villous adenoma with several foci of carcinoma in situ. Detailed investigations showed no other tumors of the gastrointestinal tract. After fi ve years of follow-up, the patient reports no complaints, and the results of laboratory testing and imaging studies are within the normal range. | Miodrag Krstic Tamara Alempijevic Bojan Stimec Marjan Micev Miroslav Milicevic Dragan Micic Goran Jankovic | 2007 | World Journal of Gastroenterology2007，13，22： | 0 |
