World J Gastrointest Endosc 2022; 14:77-84. [PMID: 35316982 PMCID: PMC8908326 DOI: 10.4253/wjge.v14.i2.77] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/20/2021] [Revised: 07/31/2021] [Accepted: 01/14/2022] [Indexed: 02/06/2023] Open
Abstract
Exposed endoscopic full-thickness resection (EFTR), with or without laparoscopic assistance, is an emergent natural orifice transluminal endoscopic surgery technique with promising safety and efficacy for the management of gastrointestinal submucosal tumors (SMTs) arising from the muscularis propria (MP), especially of the gastric wall. To date, evidence concerning duodenal exposed EFTR is lacking, mainly due to both the technical difficulty involved because of the special duodenal anatomy and concerns about safety and effectiveness of transmural wall defect closure. However, given the non-negligible morbidity and mortality associated with duodenal surgery, the recent availability of dedicated endoscopic tools for tissue-approximation capable to realize full-thickness defect closure could help in promoting the adoption of this endosurgical technique among referral centers. The aim of our study was to review the current evidence concerning exposed EFTR with or without laparoscopic assistance for the treatment of MP-arising duodenal SMTs.

Abstract
The present study was performed to evaluate the therapeutic safety and feasibility of purse-string sutures with nylon loops and metal clips under single-channel endoscopy to repair gastrointestinal wall defects that had previously developed during endoscopic full-thickness resection (EFR). A multicenter prospective cohort study of 42 patients who had developed defects of the gastrointestinal wall during EFR was conducted from April 2012 to October 2016. All lesions were endoscopically repaired with either a single-channel gastroscope (research group, n=18) or double-channel gastroscope (control group, n=24). The patients' clinical features, purse-string suturing times and complication rates were analyzed. There was no significant difference in the perforation rate between the research and control groups. There were also no significant differences in the purse-string suturing time (research vs. control group, 10.5 vs. 14.6 min, respectively; P=0.214), specimen size or complication rate (subcutaneous emphysema) between the two groups. No recurrences were observed during the follow-up period. The current data suggest that application of purse-string sutures with nylon loops and metal clips for repair of EFR-induced gastrointestinal wall defects may be safely and feasibly applied under single-channel gastroscopy as well as under double-channel gastroscopy.

Abstract
BACKGROUND Definitive chemoradiotherapy (CRT) is a reasonable approach for patients with locally advanced esophageal cancer who are not surgical candidates. This study was performed to investigate whether endosonography (EUS) assessment of tumor area response is a useful prognostic marker in patients with squamous cell carcinoma (SCC) of the esophagus who receive definitive CRT. METHODS A total of 33 patients who received definitive CRT for locally advanced esophageal SCC were enrolled. The maximal transverse cross-sectional area of the tumor was measured before and after definitive therapy. EUS response was defined as a ≥50% reduction of the tumor area after definitive CRT. RESULTS Based on EUS evaluation, there were 20 nonresponders (60.6%) and 13 responders (39.4%). The median progression-free survival (PFS) was significantly longer in EUS responders than EUS nonresponders (p = 0.005). However, there was no statistical significance in overall survival according to EUS response (p = 0.120). During multivariate analysis, EUS response to definitive CRT was the only significant factor associated with PFS (p = 0.045), whereas EUS response to definitive CRT was not associated with overall survival (p = 0.221). CONCLUSIONS A reduction of the maximal cross-sectional tumor area measured by EUS correlates with a superior prognosis in patients with locally advanced SCC of the esophagus after definitive CRT.

Abstract
The proton pumpvinhibitor, lansoprazole, is reported to have acid secretion inhibiting effect as well as anti-inflammatory effects such as inhibition of cytokine secretion from inflammatory cells. Clinically, excellent efficacy of lansoprazole is reported for not only gastric ulcer but also gastroesophageal reflux disease (GERD). Since GERD is categorized endoscopically into erosive esophagitis and non-erosive reflux disease, it is important to make accurate assessment of any improvement in the inflammatory process when using endoscopic ultrasonography (EUS) capable of visualizing the submucosal structure. We report here our experience in assessing the effect of treatment with lansoprazole on esophageal wall structure using EUS in patients with GERD. At baseline (before treatment), EUS showed abnormalities in the mucosa, submucosa and muscularis propria caused by inflammation, thickening of the entire esophageal wall and changes in the contractile properties of esophageal smooth muscles reflecting the effects of inflammation on the entire wall of the lower esophagus in reflux esophagitis regardless of whether it is erosive or endoscopically-negative. Treatment with lansoprazole resulted in normalization of esophageal wall structure and improvement of motility, suggesting that lansoprazole improves not only mucosal inflammation but also submucosal inflammation in GERD.

Abstract
Type of lymphoma and stage of disease are the two decisive prognostic factors and therapeutic determinants. For the locoregional staging, i.e. assessment of the gastric wall infiltration and perigastric lymphonodular involvement, endoscopic ultrasound (EUS) is highly useful. EUS has, therefore, to be integrated into the standard staging procedure of gastric lymphoma, although its impact on initial treatment decisions might be limited in the individual case. A benefit from the use of miniechoendoscopes, EUS elastography and EUS-guided biopsies has not yet been proven in gastric lymphoma. EUS also confers an important prognostic value regarding treatment responses to Helicobacter pylori eradication. On the contrary, EUS cannot be recommended as a regular part of follow-up investigations considering its limited value in predicting the response of the lymphoma to radiation or chemotherapy.

Abstract
This review, based on the Hennepin County Medical Center experience and review of the literature, vastly covers the up-to-date role of endoscopic ultrasonography (EUS) and EUS-guided fine-needle aspiration (FNA) in evaluating tumorous lesions of the gastrointestinal tract and adjacent organs. Emphasis is given to the tumoral and nodal staging of esophageal, pulmonary, and pancreatic cancer. This review also discusses technical, pathological, and gastroenterologic aspects and the role of the pathologist and endosonographer in the evaluation of these lesions, as well as the corresponding FNA cytology and differential diagnosis.

Radiother Oncol 2006; 78:236-44. [PMID: 16545878 DOI: 10.1016/j.radonc.2006.01.009] [Citation(s) in RCA: 125] [Impact Index Per Article: 6.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2005] [Revised: 01/16/2006] [Accepted: 01/31/2006] [Indexed: 10/24/2022]
Abstract
BACKGROUND AND PURPOSE Numerous trials have shown that pathological complete response (pCR) following preoperative chemoradiotherapy (CRT) and surgery for oesophageal cancer is associated with improved survival. However, different radiotherapy doses and fractionations and chemotherapy drugs, doses and scheduling were used, which may account for the differences in observed pCR and survival rates. A dose-response relationship may exist between radiotherapy and chemotherapy dose and pCR. PATIENTS AND METHODS Trials using a single radiotherapy and chemotherapy regimen (5FU, cisplatin or mitomycin C-based) and providing information on patient numbers, age, resection and pCR rates were eligible. The endpoint used was pCR and the covariates analysed were prescribed radiotherapy dose, radiotherapy dosexdose per fraction, radiotherapy treatment time, prescribed chemotherapy (5FU, cisplatin and mitomycin C) dose and median age of patients within the trial. The model used was a multivariate logistic regression. RESULTS Twenty-six trials were included (1335 patients) in which 311 patients (24%) achieved pCR. The probability of pCR improved with increasing dose of radiotherapy (P=0.006), 5FU (P=0.003) and cisplatin (P=0.018). Increasing radiotherapy treatment time (P=0.035) and increasing median age (P=0.019) reduced the probability of pCR. The estimated alpha/beta ratio of oesophageal cancer was 4.9 Gy (95% confidence interval (CI) 1.5-17 Gy) and the estimated radiotherapy dose lost per day was 0.59 Gy (95% CI 0.18-0.99 Gy). One gram per square metre of 5FU was estimated to be equivalent to 1.9 Gy (95% CI 0.8-5.2 Gy) of radiation and 100mg/m2 of cisplatin was estimated to be equivalent to 7.2 Gy (95% CI 2.1-28 Gy). Mitomycin C dose did not appear to influence pCR rates (P=0.60). CONCLUSIONS There was evidence of a dose-response relationship between increasing protocol prescribed radiotherapy, 5FU and cisplatin dose and pCR. Additional significant factors were radiotherapy treatment time and median age of patients within the trial.

Abstract
BACKGROUND Endoscopic ultrasonography(EUS) allows high-resolution demonstration of the entire gut wall. The aim of the study was to clarify the usefulness of the EUS in differential diagnosis of upper gastro-intestinal subepithelail lesions(SEL). METHODS From September 1998- March 2005, EUS was performed in 1600 patients. Among them, in 206pts (13%), this examination was carried out due to previous upper endoscopy, which revealed the suspicion to SEL or extraluminal compression. We studied the location, the size, echo pattern and originating layer of SEL. The results were compared with CT, angiography and operation with histology when possible. All EUS examinations were performed using Olympus GIF-130 videoecho-endoscope with 7,5/12MHz switchable radial probe. RESULTS EUS accuracy in separating intramural masses from extraluminal compression was 96%(44/46). Among 160 pts with true SEL, in 95(59.3%), EUS revealed the existence of a stromal tumor arising from muscularis propria (92) or muscularis mucosae (3). The size of the tumor varied from 5-75mm; depth: 8-40mm. 33 patients were operated on. In 14/16(87%), the EUS diagnosis of benign stromal tumor was confirmed on operation. In 18/19(95%), EUS correctly disclosed the malignant tumor. EUS accuracy in predicting malignancy was 91.5%(32/35). Findings suggestive for malignancy were: size 40mm; inhomogenicity with microcysts and irregular outer margin. In 12 pts, EUS revealed lypoma. Abberant pancreas was correctly diagnosed in all 22pts. In 16 persons, EUS disclosed submucosal cysts: 6 of them were operated on and EUS diagnosis was confirmed in all. In 10 patients EUS visualized varices. The finding was confirmed on angiography. CONCLUSION The EUS appears to be very effective in differential diagnosis of SEL in upper gastro-intestinal tract. Tumour size greater than 40mm, inhomomogenous echo pattern and irregular outer margin are very suggestive for malignancy.

Abstract
BACKGROUND Preoperative localization of pancreatic neuroendocrine tumours (NET) is usually very difficult. Noninvasive, imaging tests, such as abdominal ultrasound, CT or MRI are not sensitive enough as well as selective angiography. The aim of the study was to clarify the usefulness of the EUS in preoperative localization of the pancreatic NET. METHODS From September 1998 March 2005, EUS was performed in 1600 patients. Among them, in 10 (0.7%), this examination was carried out due to previous biochemical tests, which diagnosed the pancreatic NET. We studied the location, the size and echo-pattern of the neoplasm. The results were compared with operation and histology or EUS- FNA guided pancreatic biopsy in 9/10 patients. All EUS examinations were performed using Olympus GIF-130 videoecho-endoscope with 7,5 /12MHz switchable radial probe. RESULTS EUS correctly localized the pancreatic NET in 7/8 cases, (sensitivity:87.5%). In 2 patients, EUS accurately exclouded pancreatic NET. There were no false positive findings (specificity 100%). Six tumours were benign (75%), and two were malign (25%). We localized 6 insulinomas and single pancreatic carcinoid tumour. The median tumour size detected by EUS was 21mm. CONCLUSION EUS is highly accurate in preoperative localization of the pancreatic NET-s and We confirmed it in our study. EUS presents the method of choice for preoperative localization of the pancreatic NET.

Abstract
BACKGROUND Grade of malignancy and stage of disease are the decisive prognostic factors and therapeutic determinants in primary gastric lymphoma. It is supposed that EUS allows determination of depth of tumor infiltration and perigastric lymph node involvement, thus defining stages I1, I2, and II1. This multicenter study evaluated the accuracy of EUS in the staging of gastric lymphoma. METHODS Data from preoperative EUS procedures performed at 34 centers were compared with the histopathologic stage of resection specimens in 80 patients with newly diagnosed primary gastric lymphoma. Ten patients with stage II2 were excluded from analysis because EUS is inappropriate for the evaluation of nonregional lymph node involvement. RESULTS EUS correctly classified the lymphoma in 37 of 70 patients (53%). Sensitivity of EUS was as follows: stage I1, 67% (95% CI [38%, 88%]; p = 0.01); stage I2, 83% (95% CI [52%, 98%]; p = 0.01); and stage II1, 71% (95% CI [49%, 87%]; p = 0.02). CONCLUSION The accuracy of EUS in the local staging of gastric lymphoma has to be improved if nonsurgical treatment strategies based on the grade of malignancy and stage of the disease are to be used. Because most of the participating centers performed EUS in relatively few patients, no conclusion could be drawn with respect to accuracy in relation to EUS experience available at each center or technical considerations with respect to the types of instruments used.

Abstract
BACKGROUND Endoscopic ultrasound (EUS) is the standard modality in local preoperative staging of gastric cancers and is reputedly able to detect ascites. However, the association between ascites detected by EUS and local tumor staging, peritoneal carcinomatosis, or survival after surgery is not well documented. GOALS To assess the accuracy, sensitivity, and specificity of EUS in the preoperative staging and detection of ascites in gastric cancers. We also try to correlate ascites with histologic staging, tumor differentiation, and survival rate of gastric carcinoma after surgery. STUDY The retrospective analysis was made in 57 consecutive patients with histologically confirmed gastric adenocarcinomas that underwent EUS before surgery. The accuracy of EUS was compared with the final surgical-pathologic findings. We estimated the prognostic usefulness by analyzing the clinicopathologic features of gastric adenocarcinomas and following up their survival rates. RESULTS The overall T staging was 88% accurate by EUS. The accuracy for T staging was as follows: T1, 100%; T2, 33%; T3, 93%; and T4, 100%. About 50% of T2 cases were overstaged. The overall accuracy, sensitivity, and specificity of detecting lymph node metastasis by EUS were 79%, 79%, and 80%, respectively. One of the seven T1 cancers had regional lymph node metastasis, and it was missed by EUS, although the T classification was precisely staged based on finding submucosal invasion. A total of 22 patients (39%) had ascites detected by EUS; both the sensitivity and specificity of EUS in demonstrating ascites were 100% in our study. Ascites was significantly correlated with the depth of tumor invasion ( = 0.036), lymph node metastasis ( = 0.008), and poor cellular differentiation ( = 0.007), but it was not significantly correlated with macroscopic peritoneal carcinomatosis. The survival rate after surgical treatment was poor in those with gastric cancers with lymph node metastasis, ascites, or poorly differentiated tumors ( < 0.05). However, multivariate analysis showed that lymph node metastasis was the only significant prognostic predictor ( = 0.004). CONCLUSIONS Endoscopic ultrasound is a valuable diagnostic tool in the local staging of gastric cancers and demonstration of ascites. Although the surgical treatment of gastric cancers with lymph node metastasis, ascites, or poor differentiation had poorer survival rate, only lymph node metastasis was proved to be a significant prognostic predictor in multivariate analysis.

Abstract
The results of treatment for oesophageal carcinoma remain poor and few patients are curable by surgery alone. The use of chemoradiotherapy (CRT) given as a definitive treatment or in combination with surgery may improve locoregional control and survival, when compared with radiotherapy or surgery alone. Using the keywords "chemoradiotherapy" and "radiochemotherapy", a Medline-based literature review (1980-2001) was performed. Additional literature was obtained from original papers and published meeting abstracts. Two-year survival rates of 28-72% in squamous cell carcinoma and 14-29% in adenocarcinoma from definitive CRT were reported. This is comparable to results achievable by surgery alone. The use of preoperative CRT followed by surgery may further improve survival, but current data are insufficient to justify this approach within routine clinical practice. Acute treatment-related toxicity is increased with CRT. In selected patients with localised unresectable oesophageal cancer, definitive CRT is recommended. There are uncertainties about the role of routine surgery following CRT in patients with resectable disease. For the future, the pretreatment staging of patients needs to be improved and standardised, the optimal CRT regimen needs to be defined and the role of predictive markers for CRT response needs to be developed.

Abstract
BACKGROUND This study assesses the cost savings associated with using endoscopic ultrasound (EUS) before endoscopic retrograde cholangiopancreatography (ERCP) for evaluating patients with suspected obstructive jaundice. METHODS One hundred forty-seven patients with obstructive jaundice of unknown or possibly neoplastic origin had EUS as their first endoscopic procedure. With knowledge of the final diagnosis and actual management for each patient, their probable evaluation and outcomes and their additional costs were reassessed assuming that ERCP would have been performed as the first endoscopic procedure. Also calculated were the additional costs incurred if EUS were unavailable for use after ERCP and had to be replaced by computed tomography or other procedures. RESULTS The final diagnoses in these patients included malignancies (65%), choledocholithiasis or cholecystitis (18%), "medical jaundice" (11%), and miscellaneous benign conditions (6%). Fifty-four percent had EUS-guided fine-needle aspiration but only 53% required ERCP after EUS. An EUS-first approach saved an estimated $1007 to $1313/patient, but the cost was $2200 more if EUS was unavailable for use after ERCP. Significant savings persisted through sensitivity analysis. CONCLUSIONS Performing EUS with EUS-guided fine-needle aspiration as the first endoscopic procedure in patients suspected to have obstructive jaundice can obviate the need for about 50% of ERCPs, helps direct subsequent therapeutic ERCP, and can substantially reduce costs in these patients.

BACKGROUND Oesophageal cancer carries a poor prognosis. The 5-year survival rate following resection ranges from 10 to 35 per cent. Recent evidence suggests that the addition of non-surgical treatments to surgery may improve resection rates, reduce the risk of recurrence and improve survival. This review examines the role of preoperative chemoradiotherapy (CRT) in oesophageal cancer. METHODS A Medline-based literature review (1980-2000) was performed using the key words 'neoadjuvant or preoperative' and 'chemoradiotherapy or radiochemotherapy'. Additional literature was obtained from original papers and published meeting abstracts. RESULTS Forty-six non-randomized and six randomized trials of preoperative CRT were found. Resection rates, pathological complete response (pCR), treatment-related mortality rates and relapse patterns are documented. Improved 5-year survival rates approaching 60 per cent may be achieved following pCR. Three of the six randomized trials show a benefit in either overall survival or disease-free survival compared with surgery alone. Treatment-related toxicity can be significant. CONCLUSION Preoperative CRT may improve survival. Emerging evidence suggests that CRT alone can achieve similar survival rates to surgery alone. New imaging modalities may help to select which patients require surgery. Larger randomized trials of preoperative CRT or chemotherapy are needed to define optimal regimens and produce higher pCR rates with acceptable toxicity.

Abstract
BACKGROUND Endoscopic ultrasound (EUS) was used to evaluate cirrhotic patients with and without prior variceal hemorrhage. The findings were compared with those of EUS in noncirrhotic control subjects to determine EUS features indicative of cirrhosis and of a risk for variceal hemorrhage. METHODS Patients with cirrhosis undergoing indicated endoscopic screening for varices or surveillance after endoscopic therapy for variceal hemorrhage were studied and compared with healthy noncirrhotic control patients undergoing EUS for benign conditions. RESULTS Sixty-six cirrhotic patients (31 with prior hemorrhage) and 32 control patients were studied. Nonhemorrhage cirrhotic patients had more severe liver disease by Child's class (p = 0.02) and less beta-adrenergic blocker usage (p < 0.0001). Paraesophageal varices were detected in 97% of cirrhotic patients and 3% of control patients (p < 0.001) and were a more sensitive predictor of cirrhosis than varices at endoscopy (74%, p < 0.0001). Azygos vein and thoracic duct diameters, and gastric mucosa and submucosa thickness were greater for cirrhotic than control patients (p < 0.001). More hemorrhage patients had large (5 mm or greater) paraesophageal varices (odds ratio 3.1: 95% CI [1.1, 8.3]; p < 0.05) and paragastric varices (odds ratio 3.7: 95% CI [1.3, 10.2]; p = 0.01). Paraesophageal varix size correlated with ascites (p = 0.03) and, for nonhemorrhage patients, with Child's class (p < 0.01). CONCLUSIONS Paraesophageal and paragastric varices correlate with the presence and severity of liver disease and portal hypertension. These data support the hypothesis that large paraesophageal and paragastric varices (5 mm or greater) may be risk factors for variceal hemorrhage, an observation that merits further prospective study. Cirrhosis causes dilation of the azygos vein and thoracic duct and thickening of gastric mucosa and submucosa.

Abstract
BACKGROUND Endoscopic ultrasonography (EUS) is a standard procedure in the preoperative staging of patients with gastric carcinomas. Herein we present our experience with EUS and discuss the results and their implications for surgical therapy. METHODS A total of 116 patients with histologically confirmed gastric adenocarcinoma were referred to EUS and classified prospectively by the TNM system. The results of the preoperative endosonographic staging were compared with the definitive histopathological results after the operation. RESULTS The overall accuracy of EUS for determination of the T stage was 78%. The accuracy for the T1 and T2 stages was 80% and 63%, respectively. With 20% and 30%, there was a relatively high rate of overstaging in these cases. The accuracy for T3 and T4 tumors was 95% and 83%, respectively. The accuracy of EUS for determination of the N stage was 77%, with a sensitivity of 91% and a specificity of 84%. Resectability was predicted correctly with a sensitivity of 94% and a specificity of 83%. CONCLUSIONS Generally accepted standards for the therapy of advanced gastric carcinomas do not exist. In cases where the therapeutic strategy is surgical exploration, no preoperative staging is necessary. In cases with differentiated treatment strategies, the accuracy of EUS is not sufficient for the selection of patients for endoscopic resection. Its accuracy for submucosal cancer invasion and for the detection of lymph node metastases needs to be further enhanced. If only multimodal therapy is considered, EUS staging seems to be absolutely mandatory. Patients classified preoperatively as T1 to T3 can be operated on primarily with sufficient security. In patients where radical resection of the tumor seems doubtful, we recommend that a diagnostic laparoscopy be performed to confirm the diagnosis.

Abstract
A patient with suspected esophageal carcinoma represents a challenge to the treating physicians. Most patients present with an advanced stage of disease, and in the majority of cases only palliative treatment can be offered. Various treatment modalities are available, which are applied according to the TNM stage of the disease and the performance status of the patient. A precise histological diagnosis and highly accurate tumor staging of a patient with esophageal carcinoma is a prerequisite for the selection of the most suitable treatment option. Endoscopic ultrasound (EUS) has emerged as the most accurate diagnostic modality for locoregional staging. Problems in identifying early tumor stages or tumor strictures can be generally overcome by using miniprobe sonography (MPS). EUS/fine-needle aspiration biopsy (FNA) technology provides a valuable means of identifying suspicious locoregional lymph nodes. Patients with a proximal tumor (trachea bifurcation) should undergo bronchoscopy to rule out infiltration of the tracheobronchial system. Ultrasound (US), computed tomography (CT), and possibly magnetic resonance imaging (MRI) are the diagnostic tools of choice for extended tumor staging. After excluding extended tumor stage and severe concomitant diseases, diagnostic laparoscopy with intra-abdominal ultrasound should be performed in patients with adenocarcinoma of the esophagus prior to esophagectomy. Intra-abdominal metastases which can be missed preoperatively in some cases have to be ruled out in order to avoid unnecessary surgery.

Abstract
OBJECTIVE Endoscopic ultrasonographic (EUS) changes in gastroesophageal reflux disease (GERD) after treatment with proton pump inhibitor have been poorly evaluated. We conducted a randomized, double-blind 12-wk clinical trial to compare the EUS effects of lansoprazole to histamine H2-receptor antagonist therapy in GERD. METHODS Seventeen patients with reflux-related symptoms received 40 mg of famotidine for 6 wk or 30 mg of lansoprazole for 6 wk followed by 40 mg of famotidine or 30 mg of lansoprazole for another 6 wk, respectively. Patients underwent EUS before and at 6 and 12 wk after treatment. RESULTS Before treatment, a variable degree of wall thickening was noted on EUS in the lower esophagus, compared with 20 normal subjects. After 6 wk of therapy, esophageal wall was significantly thicker in the famotidine group compared with the lansoprazole group (p<0.01). Surprisingly, thickening of esophageal wall and abnormal architecture were also detected in endoscopically negative reflux disease. Lansoprazole was superior to famotidine in reducing the thickness of esophageal wall. CONCLUSIONS EUS was very useful for evaluation of submucosal injury in patients with GERD. EUS showed that a 6-wk course of lansoprazole therapy reduced thickening of esophageal wall, which was resistant to histamine H2-receptor antagonist therapy. Our results also suggest that inflammatory damage to the submucosal and muscle layers of the lower esophagus is the underlying mechanism of heartburn and associated symptoms in patients with endoscopically negative reflux disease.

Abstract
For patients with gastro-esophageal cancer ultrasonography (EUS) is superior to any other imaging modality in the assessment of local tumor infiltration and local lymph nodes status. EUS is especially important in the preoperative staging of patients with esophageal cancer and patients with proximal gastric cancer. Here it allows for the identification of those patients with advanced disease who are unlikely to benefit from surgery and in whom a conservative palliative treatment is indicated. In advanced gastric cancer the clinical implications of EUS less clear. Still preoperative EUS is indicated in every patient with cancer of the proximal stomach to assess tumor infiltration in the esophagus. Relatively new is the use of EUS in staging early cancers in order to select patients for local endoscopic treatment. High-frequency miniprobes are the instruments of choice for imaging these lesions. Strict criteria should be applied in the selection of patients for local endoscopic treatment of early gastro-esophageal cancers. EUS guided fine needle aspiration (EUS-FNA) is currently only indicated in patients with esophageal cancer and suspicious celiac lymph nodes. It may become more important if new treatment protocols demand more objective and reliable assessment of lymph node status.

Abstract
OBJECTIVE gastroenteropancreatic (GEP) neuroendocrine tumors, suspected on clinical basis, are often difficult to localize. We report our experience with endoscopic ultrasonography (EUS) in the preoperative localization of pancreatic endocrine tumors (PETs), compared to other imaging modalities, and in staging and following up carcinoid tumors (CTs) of the gastrointestinal (GI) wall. METHODS 50 patients (20 males; mean age 54 years), 39 with suspected PETs and 11 with GI CTs underwent EUS (Olympus GF-UM2 or GF-UM3). EUS data could be compared with resected specimens in 25 out of the 39 PETs and five out of the 11 CTs. RESULTS in the PETs group 42 tumors (35<20 mm) were removed: 23 in the pancreas, eight in the duodenum, and 11 in the lymph nodes. EUS correctly localized 20 out of the 23 (87%) pancreatic tumors, included 11 out of the 12 (91.6%) insulinomas, three out of the eight (37.5%) duodenal gastrinomas, and ten out of the 11 (90.9%) metastatic lymph nodes. Furthermore EUS accurately evaluated the depth of parietal invasion of CTs in three out of four patients (75%) (two after and one prior to endoscopic resection). In three patients EUS was confirmed as normal on resected specimens (two pancreas and one stomach). In the PETs group, a correct localization was obtained by ultrasonography (US) only in 17.4% of cases, by computed tomography (CT) in 30.4%, by magnetic resonance imaging (MRI) in 25%, by angiography in 26.6%, and by somatostatin receptor scintigraphy in 15.4%. CONCLUSION EUS must be considered the first-intention method in localizing PETs and is helpful in decision making and management of GEP endocrine tumors.

Abstract
Endoscopy plays an important role in the diagnosis and treatment of acute and chronic pancreatitis as well as pancreatic cancer. Sphincterotomy and stone removal in biliary pancreatitis, stone extraction and drainage in chronic pancreatitis, and stent implantation in pancreatic cancer are the predominant procedures. With endoscopy, minimal invasive techniques are at hand to solve urgent and long term problems.

Abstract
BACKGROUND: Endosonography (ES) is an important tool for staging malignant esophageal cancer with the TNM staging classification. ES is a safe procedure and an accurate method of staging tumor invasion (T) and lymph node involvement (N). METHODS: The author reviewed the literature on the comparative roles of computed tomography and ES as complementary staging procedures. RESULTS: Advantages of ES in staging esophageal cancer include the ability to accurately determine the layer depth of mural infiltration and to detect metastatic involvement of regional lymph nodes. Its disadvantages include its inability to identify distant metastases, to differentiate inflammation from malignant infiltration of wall layers or in lymph nodes, and to examine beyond obstructing tumors unless esophageal dilation is performed. A recent review indicates the accuracy for T staging to be 84% and N staging to be 77%. CONCLUSIONS: ES is a valuable tool in staging esophageal cancer and should be used in combination with computed tomography for highest accuracy.
