ABSTRACT

<p><b>OBJECTIVE</b>To identify the predictive factors for differentiating pancreatic ductal adenocarcinoma (PDAC) from other neoplastic solid pancreatic lesions and assess the accuracy of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) for diagnosis of PDAC.</p><p><b>METHODS</b>We retrospectively analyzed the clinical data of patients referred for EUS-FNA evaluation of pancreatic lesions in the Digestive Endoscopic Center of Nanfang Hospital between January, 2009 and May, 2016. The cases with unknown diagnosis, missing data, repeated punctures, cystic lesions and benign lesions were excluded from the analysis. The positivity rates of EUS-FNA were compared between patients with PDAC and those with non-PDAC lesions, and the sensitivity, specificity, positive predictive value, negative predictive value and accuracy of EUS-FNA were assessed in the diagnosis of PDAC. Univariate and multivariate logistic regression analyses were used to identify the factors for differentiating PDAC from non-PDAC lesions based on the demographic characteristics, clinical presentations, laboratory data, and endoscopic ultrasonography imaging features of the patients.</p><p><b>RESULTS</b>Among the 75 patients with solid neoplastic pancreatic lesions, 54 (72.0%) were found to have PDAC and 21 (28.0%) had non-PDAC lesions. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of EUS-FNA for the diagnosis of PDAC were 77.8%, 100.0%, 100.0%, 63.6% and 84.0%, respectively. No significant difference was found in the positivity rate of EUS-FNA between patients with PDAC and those with non-PDAC lesions (77.8% 76.2%, > 0.05). Multivariate regression analysis identified abdominal pain (=5.163, 95%: 1.093-24.389, =0.038), lesion size (=0.926, 95%: 0.877-0.978, =0.006), characteristics of the solid lesions (=7.105, 95%: 1.440-35.043, =0.016), and evidence of metastases (=6.165, 95%: 1.332-28.533, =0.020) as the independent factors for predicting PDAC.</p><p><b>CONCLUSIONS</b>The pretest characteristics including abdominal pain, evidence of metastases, and lesion size and lesion characteristics defined by endoscopic ultrasonography findings can reliably predict a diagnosis of PDAC. EUS-FNA has a high sensitivity and a high specificity for the diagnosis of PDAC.</p>

ABSTRACT

Objective To investigate the diagnostic value of endoscopic ultrasound-guided fine needle aspiration ( EUS-FNA) on malignant lesions in gastrointestinal adjacent tissue, and further to analyze the risk factors influencing positive rate of EUS-FNA. Methods The clinical data of 171 patients undergoing EUS-FNA from January 2009 to May 2016 were collected. The lesion location, size and characteristics, the number of needle passes, puncture suction negative pressure, size of puncture needle, and years of operator experience in EUS were retrospectively analyzed. Results The overall sensitivity, specificity, and accuracy of EUS-FNA in the diagnosis of malignant lesions were 78. 3% ( 83/106) , 100. 0% ( 65/65) , and 86. 5%( 148/171) , respectively. The univariable logistic regression analysis demonstrated that the risk factors of EUS-FNA were lesion location, lesion characteristics, and lesion size. In multivariate analysis, larger lesion size ( OR=1. 029, 95%CI: 1. 011-1. 047, P=0. 001) and lesion characteristics of solid ( OR=5. 098, 95%CI:1. 324-19. 633, P=0. 018) were independent factors affecting the positive rate of EUS-FNA. Among 171 cases performed by EUS-FNA, the incidence of postoperative complications was 1. 75% ( 3/171 ) included 2 cases of fever and 1 case of acute pancreatitis, which were improved after conservative treatment. Conclusion EUS-FNA is a safe and effective method of cytological and histological diagnosis with high accuracy and sensitivity, importantly in distinguish malignancy from benign lesion in gastrointestinal adjacenttissue. Positive rate of diagnosis on malignant lesions by EUS-FNA is positively correlated with lesion size, and EUS-FNA positive rate of solid malignant lesions is significantly higher than that of cystic lesions.

ABSTRACT

Gastrointestinal stromal tumors (GISTs) are common mesenchymal neoplasms in the gastrointestinal tract.The results of computed tomography play important roles in the diagnosis,treatment planning and follow up of GISTs. From August 2007 to January 2012,28 patients with GISTs were admitted to the Henan Provincial People's Hospital. Sixteen tumors showed extra-luminal growth,4 showed intra-luminal growth,7 involved both intra- and extra-luminal growth,and 1 showed extra-gastrointestinal growth.After administration of contrast media,9 tumors demonstrated homogeneous enhancement,18 showed heterogeneous enhancement and 1 showed non-obvious enhancement.The enhancement of tumors in arterial and venous phase was 20 Hu higher than that in plain scan.Angiogenesis was displayed in 6 tumors,and feeding arteries were observed in 3 tumors.

ABSTRACT

Objective To study the characteristics of heterotopic pancreas (HP) in upper gastrointestinal tract (UGIT) under endoscopy and endoscopic sonography ( EUS), and its endoscopic managements. Methods Data of 67 patients with pathologically confirmed HP in our hospital from March 2004 to November 2009, including clinical and endoscopic manifestations and sequelae after endoscopic resection,were retrospectively studied. Results Heterotopic pancreas were most commonly found as a single lesion in gastric antrum (62/67, 92. 5% ) and in gastric angle and duodenum as well, which were characterized by protrusion, with intact mucous membrane and centrally umbilicated. Of the 67 patients, 59 underwent EUS before endoscopic resection. Findings were heterogeneous and mixed echogenic lesions with indistinct borders involving both the second and third layers of the gastrointestinal wall, sometimes even involving the first and fourth layers. Most lesions (n =60) were removed by endoscopic mucosal resection (EMR), with basal residues in 25 cases, in which fourth layer involvement was observed in 23 cases (92. 0% ). Delayed bleeding occurred in 1 case at 3rd day after the procedure, and no other complications were observed. Complete removal was achieved in 8 cases ( including one receiving EMR previously ) with endoscopic submucosal dissection (ESD) , and there was no such severe complications as perforation. Postoperative pathological examinations revealed that the consistent rate of preoperative diagnosis with EUS was 91.5% (54/59). Conclusion Endoscopy combined with EUS is critical in diagnosis of HP in UGIT. EMR, especially with cap assistance, is the best method for those without involvement of muscularis propria, while ESD or endoscopic surveillance is a better alternative for those with 4th layer involvement.

ABSTRACT

Objective To evaluate the endoscopic features and treatment of gastrointestinal carciholds. Methods Data of 44 patients diagnosed as gastrointestinal carcinoid from 2002 to 2009, including clinical manifestation, endoscopic findings, treatment and follow-up, were analyzed retrospectively. Results Most common presentations were abdominal pain and changes in bowel habits, while some patients (n = 7 ) did not have any symptoms. Most lesions were elevated submucosal ones with normal mucosal pit pattern of type Ⅰ . Larger lesions appeared as polyps with mucosal pit pattern of type Ⅲ and 1 malignant carcinoid as type Ⅴ. Endoscopic ultrasonography were performed in 29 patients and all lesions were presented as submucosal hypoechoic masses with distinct borders. Endoscopic fulguration with high frequency current was applied in 12 patients and endoscopic mucosal resection (EMR) in 32. One patient with malignant carcinoid accepted multiple EMRs and died from lung and liver metastasis 6 months after last procedure. No recurrence was observed in other 43 patients during the follow-up visit of 3 months to 5 years. Conclusion Gastrointestinal carcinoid is lack of specific symptoms, and the diagnosis is made by endoscopic and pathologic findings.

ABSTRACT

Objective To investigate the feasibility of achieving consistent image quality with dose reduction technology in lumber spine MSCT examination with Z-axis automatic tube current modulation (ATCM). Methods Forty-eight patients diagnosed as lumber intervertebral disc protrution scanned twice by MSCT before and after interventional operations with the same coverage from third lumbar vertebra to first sacral vertebra. The first scan (FM) was with fixed tube current of 320 mAs. The follow-up scan was with ATCM with noise index (NI) of 12.0 HU. At the levels of L3-4, L4-5 and 15-S1, image quality, image noise and radiation dose were measured and analyzed. Image quality and radiation dose were compared by paired t-test and the image noise was compared by ANOVA test. Results The dosage of the ATCM had a 31.3% reduction compared with FM, the average DLP was(187.9±66.4)mGy·cm and(273.4±45.4) mGy·cm respectively, where t = 8.205, P < 0.05. The average noise and their deviations for the FM group were (9.8±2.4) HU,(9.9±2.4) HU, and (11.5±3.2) HU at level of L3-4, L4-5, 15-S1, respectively. With ATCM, the average noise was(12.0±0.8) HU, (11.7±0.6) HU, and (11.7±1.4) HU, respectively. There was statistical difference between the two groups (F = 23.31, P < 0.05). The image quality scores for the FM group were (4.7±0.3), (4.5±0.2), (4.5±0.2) and showed no statistical difference to ATCM group (4.6±0.3), (4.5±0.2), (4.5±0.2) at level of L3-4, L4-5, L5-S1, respectively, where t = 1.000, P > 0.050 Conclusion ATCM technique with the noise index setting at 12.0 HU can achieved a 31.3% dose reduction while keep the consistent image quality for lumbar spine MSCT study.

ABSTRACT

Objective To evaluate the clinical application value of multi-slice helical CT volumetric (VH) scanning in lumber spine. Methods One thousand of patients with back and leg pain who underwent CT examinations were selected as subjects. We simulated the traditional protocol of single-slice(SS) discrete scanning for L3/4, L4/5, and LS/S1 intervertebral discs. The VH scanning mode was performed with 120 kV, 210 mAs,pitch of 1.5 and coverage of 97. 5 mm. The simulated SS scanning mode was performed with 120 kV, 240 mAs and coverage of 45.0 mm. The diagnostic outcomes and the radiation doses were compared between the two scanning modes. Two groups doctors observed ten terms, including the osseous spinal stenosis,narrowed intervertebral space and so on in two scanning modes respectively. Then consistency analysis of the data was carried out. Results The VH scanning mode showed far more features than the SS mode. The detection rates of the VH mode in the osseous spinal stenosis, narrowed intervertebral space,herniated nucleus pulposus, narrowed lateral recess, vertebral lesion, hypertrophy of L5 transverse process,abnormal direction of facet, facet degeneration, lumbar spondyloschisis, and paraspinal soft tissue were 11.8% (n =118), 38. 5% (n =385), 9. 3% (n =93), 46. 8% (n =468), 31.4% (n =314), 5.7% (n =57), 25.4% (n = 254), 49. 7% (n = 497), 9.9% (n = 99), and 0. 6% (n = 6) respectively, while the detection rates of the SS mode in ten terms were 5.6% (n = 56), 0, 0. 6% (n = 6), 27. 9% (n = 279),22.4% (n =224), 1.2% (n = 12), 16.7% (n = 167), 37.2% (n =372), 0.5% (n =5), and 0.2%(n = 2) respectively. The difference between the two groups had statistically significance (average P <0.05), except the paraspinal soft tissue abnormal (P > 0.05). The detection rates of the VH mode were higher than the SS mode in the osseous spinal stenosis, narrowed intervertebral space, herniated nucleus pulposus, lumbar spondyloschisis, being 6.2% (n = 62) , 38. 5% (n = 385) , 8.7% (n = 87), and 9.4%(n =94), respectively. In addition, VH mode only partially showed the articular facets, narrowed lateral recess, hypertrophy of L.5 transverse process, and paraspinal soft tissue. We could not acquire the imaging slices paralleling to intervertebral discs in SS mode in 467 patients (46.7%) with lumbosacral angle greater than 35°. The radiation dose of VH mode (164.9 mGy/em) was slightly higher than SS mode (147.0 mGy/cm) Conclusion MSCT VH scanning mode can significantly improve the diagnostic rate of lumbar spine diseases compared with SS mode, and was not restricted by the lumbosacral angle with slightly increasing radiation dosage.

ABSTRACT

Objective This study was to investigate the relation of nitric oxide synthase with cell proliferation and apoptosis in hepatocellular carcinoma (HCC). Methods The expression and localization of inducible nitric oxide synthase (iNOS) and PCNA in 21 patients with HCC were studied by immunohistochemistry. Apoptotic cell in tissue section was detected by TUNEL (terminal deoxynucleotidyl transferase [TdT] mediated desoxyuridinetriphosphate [dUTP] nick end labeling). Results The iNOS protein was markedly expressed in the liver tissue of hepatic cirrhosis or chronic liver hepatitis, which was close to tumor edge. Meanwhile it was weakly or undetectable in the liver tissue localized beyond 1.5 cm from the tumor edge. The iNOS protein was markedly expressed at the invasive tumor edge and HCC cells that invased into stroma, but it was weakly or undetectable at the most tumor core. The expression of iNOS was correlated with the proliferative activity of cells, and the number of apoptotic cells was correlated to the number of PCNA positive cells ( P

ABSTRACT

AIM: To observe the effects of Egr-1 gene knockout on the expression of inflammatory-related factors in pancreatic tissue in a mouse acute pancreatitis model.METHODS: The experimental pancreatitis was induced by high-dose of cearulein in wildtype mice and Egr-1 knockout mice.The pancreatitis indexes,such as serum amylase,pancreata edema,and myeloperoxidase(MPO) levels in pancreata and lungs were recorded.The mRNA levels of tissue factor(TF),plasminogen activator inhibitor(PAI-1),monocyte chemoattractant protein(MCP-1),Gro-1,IL-6 and ICAM-1 were measured by quantitative PCR.RESULTS: Contrary to wildtype mice,typical pancreatitis was not induced by high-dose cearulein in the Egr-1 knockout mice,not only markedly reduced edema in pancreata and lungs,but decreased MPO levels in lungs as well were found.Furthermore,the mRNA of TF,PAI,MCAP,ICAM-1 and IL-6 in pancreata were significantly decreased in Egr-1 knockout mice.CONCLUSION: The severity of pancreatitis and lung damage is ameliorated in Egr-1 knockout mice stimulated by high-dosage of cearulein,which was probably mediated by decreasing expression of inflammatory-related factors in pancreata,such as TF,PAI,MCP-1,ICAM-1 and IL-6.
