RESUMO
OBJECTIVES: To evaluate the diagnostic yield of endoscopic ultrasonography in loco-regional staging of gastric cancer in our medium and to determine the impact of this technique on later therapeutic management. MATERIAL AND METHODS: This is a retrospective study carried out on patients histologically diagnosed with gastric adenocarcinoma who had been referred for endoscopic ultrasonographic examination. The technique results were compared with those obtained from surgical samples and/or from exploratory laparoscopy- laparotomy. We compared the initial therapeutic decision based on conventional diagnostic techniques with the final therapeutic management based on the endoscopic ultrasonography results. RESULTS: Forty-six patients with gastric adenocarcinoma were included in the study (a reference exploration was available in 36 cases). Diagnostic precision was 70% in stage T, while in stages T1, T2, T3 y T4 was 100, 38, 82, and 100%, respectively. The sensitivity and specificity to differentiate T1-2 from T3-4 was 94 and 85%, respectively. We could not identify factors associated with obtaining a correct diagnosis in staging T. Diagnostic precision was 72% for stage N (N0: 58%; Nx 88%). The presence of free perigastric fluid was identified in 7 cases; the presence of peritoneal carcinomatosis was later confirmed in 5 of these. The result of endoscopic ultrasonography led to a modification in the subsequent therapeutic management in 13 patients (28%). CONCLUSIONS: Endoscopic ultrasonography is a useful technique for loco-regional staging of gastric adenocarcinoma, which may have important implications in the therapeutic management of these patients.

OBJECTIVE: This study evaluated Helicobacter pylori eradication therapy in terms of symptomatic response in patients with functional dyspepsia. On the other hand, we analyzed the importance of histologic findings as a predictor of treatment response. In particular, we studied whether antral gastritis (which is associated with peptic ulcer) may predict a greater symptomatic response to Helicobacter pylori eradication in functional dyspepsia. PATIENTS AND METHODS: This prospective, randomized, single-center trial included 48 patients with functional dyspepsia and Helicobacter pylori infection (27 women and 21 men, mean age 37 +/- 13.5 years). Twenty-seven patients received a 10-day course of rabeprazole, amoxicillin, and clarithromycin (eradication group), followed by 20 mg of rabeprazole for 3 months. Twenty-one patients received 20 mg of rabeprazole for 3 months (control group). Patients were followed up over a 1-year period. All patients completed the Dyspepsia-Related Health Scale Questionnaire, which studies four dimensions: pain intensity, pain disability, non-pain symptoms, and satisfaction with dyspepsia-related health. RESULTS: There was significant symptomatic improvement (p < 0.002) after 6 and 12 months, which was similar with both treatments. In the multivariate analyses, eradication therapy and less severe symptoms before treatment were the only independent factors. The symptomatic response to Helicobacter pylori eradication after 6 months was significantly greater as compared to control therapy (p = 0.01) in patients with antral gastritis and in the non-pain symptoms dimension of the questionnaire. CONCLUSIONS: Both treatments proved to be clinically beneficial in patients with functional dyspepsia. We observed a tendency to greater symptomatic benefit with Helicobacter pylori eradication therapy when compared to control treatment in patients with functional dyspepsia and in a population with a high prevalence of this infection. There is a tendency to symptomatic benefit with Helicobacter pylori eradication therapy in patients with antral gastritis.

BACKGROUND: Patients with inflammatory bowel disease may suffer one or more extraintestinal manifestations during the course of their condition, these being more frequent in Crohn s disease. The aim of our study was to evaluate the prevalence of extraintestinal manifestations in patients with Crohn s disease in our healthcare area, and to assess the relationship between its presence and diverse clinical-evolutionary variables. MATERIAL AND METHODS: Extraintestinal manifestations in 157 patients diagnosed with Crohn s disease in our center were retrospectively studied. The clinical-evolutionary characteristics of this population were compared with respect to the presence or absence of different extraintestinal manifestations. RESULTS: Seventy-two patients (46%) presented at least with one extraintestinal manifestation. Thirty-one percent were colitis-related manifestations (22% rheumatologic, 13% muco-cutaneous, 4% ophthalmologic), 11% cholelithiasis, 8% nephrolithiasis, 3% thromboembolic illness, and other manifestations were less frequent. Fourteen percent presented with more than one extraintestinal manifestation. Rheumatologic and muco-cutaneous manifestations were significantly more frequent in patients with disease confined to the colon. Cholelithiasis was significantly associated to those over 40 and also to males. Nephrolithiasis was also significantly associated to those over 40, and thromboembolic illness was linked to females. CONCLUSIONS: forty-six percent of patients with Crohn s disease presented at least with one extraintestinal manifestation. Thirty-one percent presented with colitis-related manifestations, rheumatologic and muco-cutaneous manifestations being the most frequent, whereas hepatic manifestations were infrequent. Rheumatologic and muco-cutaneous manifestations were more frequent in patients with disease confined to the colon.

INTRODUCTION: Aneuploidy has been observed in 6-27% of lesions known to be precursors of colorectal cancer, such as adenomas or ulcerative colitis. It has been suggested that aneuploidy may predispose to malignancy in these cases. However, its role in the adenoma-carcinoma sequence has not been definitely established. The objective of this study was to assess the incidence of aneuploidy in colon adenomas, as well as to study its possible role in the adenoma-carcinoma sequence. MATERIAL AND METHODS: The study was performed on a series of 57 large bowel adenomas measuring 10 mm or more, collected from 54 consecutive patients. All specimens were obtained either by endoscopic or by surgical resection. There were 49 adenomas with low-grade dysplasia, two with high-grade dysplasia, two intramucous carcinomas, and four microinvasive carcinomas. A flow cytometric DNA analysis was performed in fresh specimens following Vindelov's method. RESULTS: Aneuploid DNA was detected in five out of 49 low-grade dysplasia adenomas (10%), in all four high-grade dysplasia adenomas or intramucous carcinomas (100%), and in three out of four microinvasive carcinomas (75%). The association between aneuploidy and high-grade dysplasia adenomas, intramucous, or microinvasive carcinoma was statistically significant (p < 0.001). No association was found between aneuploidy and any of the following features: age, gender, clinical symptoms of patients, and size or location of adenomas. CONCLUSIONS: The incidence of aneuploidy in this series was 10% in low-grade dysplasia adenomas, and 87% in high-grade dysplasia adenomas or carcinomas, and this difference was statistically significant. These findings suggest that aneuploidy may play a role in the adenoma-carcinoma sequence.

We report a case of solitary rectal ulcer (SRU) in a patient who had been previously diagnosed of granulomatous appendicitis. Both entities were histologically confirmed. The patient is asymptomatic after appendectomy done one and a half years ago, demonstrating the low recurrence rate of granulomatous appendicitis and the silent course of solitary rectal ulcer in many patients. Both entities may be related.

INTRODUCTION: Infection with the parasite Anisakis simplex is common in Japan and northern European countries. The number of reported cases in Spain has increased since the first description in 1991. The aim of the present study was to evaluate the incidence, clinical patterns, histopathological lesions, treatment, and outcome of Anisakis simplex infection in our environment. MATERIAL AND METHOD: Cases of gastrointestinal anisakiasis diagnosed in our center from December 1999 to January 2002 were studied. Only patients with detection of the parasite in oral endoscopy or the surgical specimen and those with elevated levels of specific IgE to Anisakis simplex, a clinical picture compatible with anisakiasis, or a history of raw fish intake were included. Epidemiological, clinical and laboratory data, as well as diagnostic, histopathologic and therapeutic features, and outcome in these patients were recorded. RESULTS: Twenty-five cases of gastrointestinal anisakiasis were diagnosed during the study period, representing an incidence of 3.87 cases per 100 000 inhabitants/year. All the patients had ingested raw anchovies. Two groups were observed. The first group was composed of 10 patients with a gastric form of the infection, in which the main symptom was epigastralgia (90%). Oral endoscopy was performed in all patients and the parasite was detected in five (50%). The second group was composed of 15 patients with intestinal involvement in which the main manifestations were symptoms mimicking appendicitis (80%). The most frequent finding of laparotomy and/or imaging tests (abdominal ultrasonography, intestinal transit, abdominal CAT) was terminal ileitis (80%). Seven patients underwent surgery: intestinal resection was performed in four with detection of Anisakis simplex in three. Eosinophilic infiltration was found in all surgical specimens. Treatment was symptomatic in most of the patients and outcome was favorable in all. CONCLUSIONS: Infection with Anisakis simplex should be investigated in patients with abdominal pain after intake of raw fish, ileitis of unclear origin, or eosinophilic gastroenteritis.

A case of gaseous gangrene by Clostridium septicum associated with colorectal cancer is presented. The patient evolved rapidly towards septic shock and death. Autopsy showed occult neoplasm and pelvic and retroperitoneal myonecrosis. An exceptional finding was that of myocarditis in which thick gram-positive bacilli were identified. A review of the literature was carried out regarding the pathogenesis and clinical manifestations of this disease. The association of colonic neoplasm and Clostridium septicum may be related with the sensitivity of the cells of this neoplasm to the toxins of the microorganisms. The usefulness of this cytotoxicity is being tested in the therapeutic reduction of tumoral mass. With respect to clinical attitude, all the authors agree on the need for clinical suspicion as to the possible existence of occult colon neoplasm in individuals with septic shock by gaseous gangrene with no obvious entry site. Diagnosis is performed by imaging techniques with barium enema and if this is normal colonoscopy is carried out. Emergency treatment consists in laparotomy with resection of the neoplasm and debridement of the area accompanied by hyperbaric oxygen and antibiotics.

PURPOSE: To evaluate in a prospective multicenter setting the clinical utility of polyurethane stents in the percutaneous management of epiphora. MATERIALS AND METHODS: Patients (N = 163; age range = 22-85 y, mean = 52 y; 29 men, 134 women) with severe epiphora had stents (n = 183) inserted under fluoroscopic guidance in 180 lacrimal systems (unilateral = 146; bilateral = 17) to treat complete (n = 172) or partial (n = 8) obstruction of the nasolacrimal duct or sac. The junction between sac and duct was the most frequent location (n = 102), followed by the sac alone (n = 48), and the duct alone (n = 30). The etiology of the obstruction was idiopathic in 113 cases (63%) and chronic dacryocystitis in 67 (37%). The set designed by Song was used in all patients and the original technique was slightly modified by the authors. All patients were treated on an outpatient basis. Average time of the procedure was 14 minutes (range = 3-70 min). RESULTS: Initial technical success rate of stent placement was 97%. Resolution of epiphora was complete in 175 eyes and partial in five. On follow-up (mean = 450 d; range = 8-730 d), 157 of 183 stents remained patent (85.8%). Of the 24 obstructed, 19 were easily withdrawn and 17 of these patients remained asymptomatic for a mean of 15 months (secondary patency rate = 89.5%). CONCLUSIONS: The procedure is simple and safe. It can be performed on an outpatient basis and the original technique could be improved with some technical modifications. It is well tolerated by patients and may be considered as a valid alternative technique for the resolution of epiphora.

A 40-year-old patient with clinical manifestations of impaired general status, abdominal pain and signs of malabsorption of six months duration was diagnosed as adult celiac disease. Treatment was initiated with a gluten-free diet and there was improvement. Later, in spite of the patient's compliance with dietary treatment, he suffered two episodes of intestinal obstruction. In the first episode the symptomatology remitted with intestinal rest, parenteral feeding and steroids, but clinical manifestations persisted in spite of medical treatment so exploratory laparotomy was realized. On pathological study were found ulcers that affected the mucosa and submucosa, inflammatory infiltrate without granulomas, and partial villous atrophy in the adjacent non-ulcerated mucosa, all compatible with a nongranulomatous ulcerative enteritis. The course was torpid and the patient died in a few months.
