RESUMO
A 39-year-old woman with a history of Crohn's disease presents at the Emergency Room for a 2-hour long colicky abdominal pain with bloating, vomiting and no gas passing. She refers an accidental ingestion of a foreign body three weeks ago, a dental post and crown (she is currently using an invisible orthodontic technique). Her Crohn's disease affects the terminal ileum, and was diagnosed 8 years before, she has been suffering mild to no symptoms for the last years, but due to evidence of biochemical, endoscopic and ultrasonographic activity she is on Ustekinumab 90mg subcutaneously every 4 weeks, after Infliximab and Adalimumab loss of response. An abdominal x-ray reveals bowel dilation and hydro-aerial levels, as well as a radiopaque element in the pelvis consistent with the dental post and crown. CT-scan confirms the bowel obstruction, ileal stenosis is found. Intestinal ultrasound is performed at our centre finding a long ileal stenosis, 33 cm, thickened wall 5.6mm, destructuring of the layer pattern, hyperemia (modified Limberg score 3), ileoileal fistula with no collection associated, and a prestenotic dilation of 40mm. The dental foreign body is found, non-impacted, in the prestenotic dilated loop. Even though an initial course of intraneous steroids is ordered, due to previous medical history of a persistent active Crohn's disease with loss of response to three advanced therapies, as well as the very low probability of progression of the foreign body along with the risk of permanent impaction or perforation, surgery is indicated. Ileocecal resection with extraction of the foreign body is performed uneventfully.
RESUMO
A 58-year-old, otherwise healthy male presented to the Emergency Room due to a 24-hour-long bloody diarrhea and constitutional syndrome. Colonoscopy confirmed the presence of a colonic neoplasia. A CT scan revealed an irregular surface and poorly delimited hypodensity of liver segment 5, next to the neoplasia, with malignant infiltration being impossible to rule out.

Tuberous sclerosis complex (TSC) is a rare disease which is characterized by widespread of a variety of benign tumors in multiple organs. Renal angiomyolipomas (AMLs) are the primary cause of morbidity in TSC due to anemia, renal failure or spontaneous bleeding. In contrast, the hepatic involvement is unusual and it is infrequently described in literature.

INTRODUCTION: the characteristics, screening, and survival of hepatocellular carcinoma (HCC) for patients without cirrhosis have not been fully studied. METHODS: A retrospective cohort study was performed in non-cirrhotic patients with histological HCC, between January 2004 and October 2018. Their characteristics, treatment, follow-up and overall survival were described. RESULTS: 25 of the 332 patients with HCC met the inclusion criteria (7.5%), 76% were males and the median age was 69.9 years. The main etiology of liver disease was the hepatitis B virus (HBV) (32%), followed by non-alcoholic steatohepatitis (NASH) (20%). Liver fibrosis was mild (0-1) in 44% of cases. The nodule was diagnosed by ultrasonography in 32% of cases, 60% were found incidentally and 8% due to clinical symptoms. The Barcelona Clinic Liver Cancer (BCLC) staging was 0 in 4% of cases, A in 88%, B in 4% and C in 4%. The main initial treatment was surgical resection (76%) and 8% refused to be treated. Percutaneous ethanol injection, chemoembolization, sorafenib and palliative care were each performed in 4% of cases. There were some complications in 21% of patients treated with surgery, half of them were severe. The median follow-up was 22.2 (2.9-150.6) months and 56% were in remission and the median overall survival was 57.4 ± 29.8 months. The overall cumulative survival at 1, 3 and 5 years was 84%, 61.6% and 47.9%, respectively. CONCLUSION: 7.5% of HCC presented without cirrhosis and almost half of patients had mild fibrosis. HBV was the main cause of HCC, followed by NASH. The most frequent BCLC stage at diagnosis was early stage and surgery was the most common treatment. Overall cumulative survival at 5 years was almost 50%.

BACKGROUND: the training program of the gastroenterology specialty that is mandatory for resident physicians, obliges them to be proficient in diagnostic and therapeutic digestive ultrasound tools. METHODOLOGY: the Asociación Española de Ecografía Digestiva (AEED) performed a survey of the 93 Departments of Gastroenterology with training programs for resident physicians in gastroenterology, in order to assess the exact situation of training in digestive ultrasound in Spain. RESULTS: only 31 of the 93 (33%) Departments of Gastroenterology were able to provide training in Digestive Ultrasound. Moreover, 33% (48 out of 148) of the residents in gastroenterology did not receive specific training in digestive ultrasound. Whereas, 31% (46 out of 148) had received some specific training, but with ample room for improvement. These deficiencies were spread throughout the Spanish regions (Autonomous Communities) in an uneven manner, with almost half totally lacking gastroenterology departments that were capable of providing digestive ultrasound training. CONCLUSIONS: there is a significant deficit of gastroenterology departments capable of providing training in digestive ultrasound to residents, causing a significant training inequality. Until this situation can be reversed, the AEED has designed a training project in digestive ultrasound aimed at providing adequate training to all residents in gastroenterology as required.

INTRODUCTION: A high percentage of older patients with early-stage hepatocellular carcinoma (HCC) are potential candidates for percutaneous ablation. MATERIAL AND METHODS: We prospectively assessed data from patients older than 70 years with HCC. We determined their demographic and clinical characteristics, the treatment provided and the response, complications and survival among those treated with radiofrequency ablation (RFA) and/or percutaneous ethanol injection (PEI). RESULTS: Of 194 patients with HCC, 84 were older than 70 years (43.3%). The mean age was 76.8 ± 4.5 years. Seventy-five percent were male and 91.7% had cirrhosis. Cancer was initially identified by a surveillance program in 61.9%. According to the Barcelona Clinic Liver Cancer staging system, 60.7% were classified as having early stage cancer (0-A), 19% as stage B, 12% as stage C, and 8.3% as stage D. Potentially curative initial treatment was provided in 38.2% (surgical resection in 4.8%, PEI in 22.6%, RFA in 4.8%, PEI+RFA in 6%), transarterial chemoembolization in 20.2%, and sorafenib in 3.6%. Twenty-five percent of patients were not treatment candidates and 13% refused the recommended treatment. The median follow-up after percutaneous ablation was 23 months (IQR 14.2-40.6). The mean number of sessions was 3.5 ± 2.2 for PEI and 1.8 ± 1.6 for RFA. The complications rate per session was 4%. Remission was achieved in 35.7%. The overall median survival was 45.7 months (95% CI 20.8-70.6). CONCLUSIONS: Almost half of the patients with HCC in our sample were elderly and more than half were diagnosed at an early stage. Percutaneous ablation was performed in one-third of the sample, achieving remission in 37.5%. There were few complications. Therefore, these patients should be assessed for percutaneous ablation.

UNLABELLED: Hepatocellular carcinoma (HCC) is the most frequent cause of mortality in patients with liver cirrhosis. There are no prospective series from a single tertiary hospital in Spain. MATERIAL AND METHODS: We performed a prospective study of patients with HCC in our center. Clinical and epidemiological characteristics, diagnostic method, staging according to the Barcelona Clinic Liver Cancer (BCLC) system and treatment were analyzed. RESULTS: A total of 136 patients were included (80.9% men). The mean age was 66.62 ± 11.68 years and 91.2% were cirrhotic. Hepatitis C virus (HCV) was the leading cause of liver disease (38.97%). The suspected diagnosis was established by a surveillance program in 63.2%. Noninvasive American Association criteria for the Study of Liver Diseases (AASLD) were the main diagnostic method (73.5%). According to the BCLC, 58.1% were in the early stage (0-A), 21.3% in stage B, 12.5% in stage C and 8.1% in stage D. Early stage patients had followed a surveillance program more frequently than those with non-early stages (79.75% versus 44.35%, p <0.001). Potentially curative initial treatment was used in 45.58%, the most common treatment being percutaneous ethanol injection (23.13%). CONCLUSIONS: Most patients with HCC in our hospital have cirrhosis, the most frequent cause being HCV. HCC surveillance in at-risk patients could increase diagnosis of HCC at an early stage. We achieved an early diagnosis in more than half of cases. The most common initial treatment was percutaneous therapy.

UNLABELLED: The aim of this study was to evaluate the utility of endoscopic ultrasonography in the etiological diagnosis of patients initially diagnosed with acute idiopathic pancreatitis and to determine the clinical and laboratory factors related to the results of this technique. MATERIAL AND METHODS: We studied 73 patients initially diagnosed with acute idiopathic pancreatitis and referred to our service for biliopancreatic endoscopic ultrasonography. A positive result was considered to be identification of at least one possible cause of pancreatitis, excluding patients in whom the only echoendoscopic finding was chronic pancreatitis. The clinical characteristics and clinical course of these patients were compared with the results of the technique. RESULTS: Endoscopic ultrasonography diagnosed at least one possible cause of acute pancreatitis in 32 patients (44%). The most frequent diagnoses were cholelithiasis (16%) and biliary sludge (20%). The diagnostic yield of endoscopic ultrasonography was lower in patients with prior cholecystectomy (16% vs. 49%; p=0.037) while a positive result was more likely in patients with elevated glutamyl oxaloacetic transaminase (GOT) or glutamyl pyruvic transaminase (GPT) levels at diagnosis of acute pancreatitis (GOT: 68 vs. 31%; p=0.002; GPT: 63 vs. 26%; p=0.001). No differences were found in diagnostic yield according to whether endoscopic ultrasonography was performed during the first episode of pancreatitis (48%) or in recurrent episodes (37%) (p=0.40). Over a mean follow-up period of 28 months, recurrence of new episodes of pancreatitis was significantly lower in patients with an etiological diagnosis (3 vs. 22%; p=0.02). CONCLUSIONS: Endoscopic ultrasonography is a useful technique in the etiological diagnosis of acute pancreatitis of unknown origin, especially in patients with elevated transaminase levels and/or without cholecystectomy. This technique should be used in the first episode of acute idiopathic pancreatitis.

OBJECTIVE: To assess the value of contrast-enhanced ultrasound in the detection of arterial hypervascularity as a diagnostic criterion of hepatocellular carcinoma (HCC) in patients with focal lesions and liver disease. PATIENTS AND METHODS: This prospective study included patients with chronic liver disease and focal liver lesions on ultrasound (US) examination. SonoVue was used as contrast agent. We employed a US imaging technique with contrast-specific software operating at a low mechanical index (< 0.14) (Hitachi EUB 6500). The contrast enhancement pattern was analyzed during the arterial phase and classified as diffuse (homogeneous or heterogeneous), peripheral, adjacent parenchyma-like enhancement, and absent. The diagnostic procedure was completed by combined study with computed tomography, magnetic resonance imaging, histologic data and clinical features. RESULTS: A total of 23 nodules in 22 patients were included in the study (one patient had two different US lesions). The final diagnosis was hepatocellular carcinoma (HCC) in 12 patients, benign lesions in nine, metastases in one and cholangiocarcinoma in one. In the 10 patients with diffuse contrast enhancement, the lesion was malignant and in the eight patients with diffuse homogeneous enhancement, the lesion was a HCC. Seventy-five percent of the patients with HCC had a diffuse enhancement pattern during the arterial phase. This pattern involved malignancy with 71.4% sensitivity, 100% specificity, 100% positive predictive value, 69.2% negative predictive value, and 82.6% accuracy. The diffuse homogeneous pattern involved HCC with 66.7% sensitivity, 100% specificity, 100% positive predictive value, 73.3% negative predictive value and 82.6% accuracy. CONCLUSIONS: Contrast-enhanced US with SonoVue allows the vascularity of focal liver lesions to be assessed. In our study, 75% of patients with HCC showed arterial hypervascularity. A diffuse homogeneous enhancement pattern during the arterial phase was highly specific to HCC. In cirrhotic patients, this arterial pattern could avoid the need for further investigations, although clinical staging should be completed with another diagnostic test.

Pancreatic metastases represent 2% of pancreatic tumors. The neoplasms most frequently metastasizing to the pancreas are breast, lung, melanoma and kidney tumors. We present the cases of two patients with pancreatic metastases from renal carcinoma diagnosed 4 and 8 years after the diagnosis and surgical treatment of the primary renal tumor. In both patients, endoscopic ultrasound was useful in the detection and characterization of these pancreatic lesions and allowed fine-needle aspiration for cytological study to be performed.

INTRODUCTION: Most patients with uninvestigated dyspepsia are diagnosed with functional dyspepsia. Various types of Helicobacter pylori gastritis have been described, each of which is associated with a distinct natural history of the infection (i.e. a different risk of ulcer or gastric cancer). OBJECTIVE: To determine the clinical and pathological characteristics of patients with uninvestigated dyspepsia in our area and the prevalence of the distinct types of H. pylori gastritis among patients with functional dyspepsia. MATERIAL AND METHODS: Ninety-eight patients (47 men and 51 women, mean age 35.8+/-13 years) with uninvestigated dyspepsia were included in this study. All the patients completed the Dyspepsia-Related Health Scale and all patients underwent gastroscopy with biopsy and the C13-urea breath test. RESULTS: Fourteen patients had organic causes of dyspepsia and 78 had functional dyspepsia. Fifty-one patients with functional dyspepsia (65%) had H. pylori infection; of these, 27 had pangastritis, 21 had antrum-predominant gastritis, 2 had multifocal atrophic gastritis and 1 had normal gastric mucosa. Among uninfected patients, 2 had multifocal atrophic gastritis. CONCLUSIONS: The prevalence of functional dyspepsia in this series was 85%. Twenty-seven percent of patients with functional dyspepsia had a combination of H. pylori infection and antrum-predominant gastritis, the type of gastritis predisposing to duodenal ulcer. Only 5% of the patients had multifocal atrophic gastritis, which is associated with a high risk of gastric cancer.
